It is perfect for a casual weeknight dinner or when you want to impress someone without spending hours in the kitchen.

Why You’ll Love This Recipe

• Bold flavor — The buffalo sauce brings a punchy, vinegary heat that gets balanced beautifully by the cool, creamy coleslaw.
• Crunch factor — The seasoned flour crust fries up shatteringly crisp, staying crunchy even after being tossed in the sauce.
• Simple ingredients — Everything comes from a standard grocery list, and most items are probably already sitting in your pantry.
• Restaurant quality at home — This tastes like something from a proper Canadian chicken shop, but you control the ingredients and the heat level.

What Makes This Recipe Special

The magic here comes from the contrast. You have a hot, crispy, spicy chicken breast against a cold, creamy, tangy slaw, all tucked into a soft, slightly sweet brioche bun. The buffalo sauce clings to the craggy crust, and the pickles add a sharp, briny pop that cuts through the richness. It is a classic Canadian fast-food favorite, and honestly, the homemade version tastes even better because you can adjust the heat to your own tolerance.

Ingredients You’ll Need

Every ingredient has a specific job here, so let’s break down what you need into easy categories. The measurements below match the recipe exactly, so no guessing.

For the Buffalo Sauce

• Frank’s RedHot Original Cayenne Pepper Sauce (1/2 cup / 120 ml) — This is the backbone of the sauce. It brings that signature vinegary heat. Frank’s is ideal here, but any cayenne-based hot sauce will work.
• Unsalted butter (1/4 cup / 60 g) — It mellows the heat and gives the sauce a silky, rich texture that clings to the chicken.
• White vinegar (1 tbsp / 15 ml) — Adds a bright, sharp tang that brightens the whole sauce.
• Garlic powder (1/4 tsp) — A subtle savory note that rounds out the flavors without being overpowering.
• Worcestershire sauce (1/4 tsp) — Brings umami depth. That little splash makes the sauce taste more complex.

For the Coleslaw

• Finely shredded green cabbage (2 cups / 150 g) — The base of the slaw. Pre-shredded bags work fine, but shredding your own gives a fresher crunch.
• Shredded carrots (1/4 cup / 30 g) — Adds a touch of sweetness and color.
• Full-fat mayonnaise (1/4 cup / 60 g) — Creaminess. Full fat matters here, because it provides the richness that balances the spicy chicken.
• Apple cider vinegar (1 tbsp / 15 ml) — Gives the slaw a gentle tang without being harsh.
• Sugar (1 tsp) — Just enough to round out the acidity.
• Celery salt (1/4 tsp) — An often-overlooked addition that gives the slaw that classic deli-style flavor.

For the Chicken

• Boneless, skinless chicken breasts (4, about 6 oz / 170 g each) — You are looking for even thickness so they cook uniformly. Pounding them helps.
• Buttermilk (1 cup / 240 ml) — This tenderizes the chicken and helps the flour coating stick. It also adds a subtle tang.
• Kosher salt (1 tsp for the brine + 1 tsp for the flour) — Seasoning at two stages makes a big difference in flavor.
• Black pepper (1/2 tsp) — A little warmth and bite.
• All-purpose flour (1 1/2 cups / 190 g) — The base of the crispy coating.
• Paprika (1 tbsp) — Gives the crust color and a mild, sweet pepper flavor.
• Garlic powder (1 tsp) — Savory depth in the crust.
• Onion powder (1 tsp) — Another layer of savory flavor.
• Cayenne pepper (1/2 tsp) — A little extra kick in the flour. Dial it back if you are heat-sensitive.
• Baking powder (1/2 tsp) — This is the secret to a lighter, airier crust. It creates tiny bubbles in the coating that crisp up beautifully.

For Assembly

• Brioche burger buns (4, toasted) — Their soft sweetness is the perfect foil for the spicy chicken.
• Dill pickle slices — The briny crunch cuts through the heat and richness. Do not skip them.
• Vegetable oil (about 4 cups / 960 ml, for frying) — Neutral oil with a high smoke point. Canola or peanut oil also work well.

Equipment Needed

The right tools make frying safer and easier. Here is what you will want to have on hand.

• Deep-fry thermometer — This takes the guesswork out of oil temperature. If you do not have one, a small piece of bread can test the heat instead.
• Heavy-bottomed pot or Dutch oven — It holds heat steadily and prevents the oil from dropping too much when you add the chicken.
• Meat mallet or rolling pin — Pounding the chicken to an even thickness ensures it cooks through without drying out.
• Wire rack set over a baking sheet — This keeps the fried chicken crispy by allowing air to circulate underneath instead of trapping steam.
• Shallow dishes — You need two: one for the buttermilk soak and one for the seasoned flour.

Instructions to Prepare Mary Brown’s Buffalo Mary

The process flows in stages — sauce first, then slaw, then the chicken. Take your time with the frying step; that is where the magic happens.

• Make the buffalo sauce — In a small saucepan over medium-low heat, combine the hot sauce, butter, vinegar, garlic powder, and Worcestershire sauce. Stir gently until the butter melts and everything comes together. Do not let it boil. Keep it warm while you work.
• Make the coleslaw — Whisk together the mayonnaise, apple cider vinegar, sugar, and celery salt in a medium bowl. Add the cabbage and carrots, toss to coat, then cover and refrigerate. The cold slaw is what makes the sandwich work.
• Pound the chicken — Place each breast between two pieces of plastic wrap and pound to an even 1/2-inch thickness. This guarantees it cooks evenly in the oil.
• Soak in buttermilk — In a shallow dish, combine the buttermilk with 1 teaspoon kosher salt and 1/2 teaspoon black pepper. Add the chicken, turning to coat. Let it sit for at least 10 minutes, or up to 30 if you have the time.
• Prepare the seasoned flour — In a separate shallow dish, whisk together the flour, paprika, garlic powder, onion powder, cayenne, baking powder, and the remaining 1 teaspoon kosher salt.
• Heat the oil — Fill your pot with about 4 cups of vegetable oil and heat over medium-high until it reaches 350°F / 175°C. No thermometer? Drop in a small piece of bread — it should brown in about 60 seconds.
• Dredge the chicken — Pull each breast from the buttermilk, letting the excess drip off. Press it into the seasoned flour, shake off the excess, and set it on a wire rack.
• Fry in batches — Carefully lower 2 pieces into the hot oil. Fry for 6-7 minutes, turning once, until the crust is deep golden brown and the internal temperature reads 165°F / 74°C. Transfer to the wire rack.
• Repeat with the rest — Fry the remaining chicken the same way. Keep the cooked pieces in a warm oven at around 200°F / 95°C if you need to hold them.
• Coat in sauce — Toss each fried breast in the warm buffalo sauce until completely coated. Let the excess drip back into the pan.
• Toast the buns — On a skillet or in a toaster, toast the brioche buns until the cut sides are golden brown.
• Assemble the sandwiches — On each bottom bun, layer a few pickle slices, then the sauced chicken. Add a generous spoonful of coleslaw and top with the other bun half.
• Serve immediately — This sandwich is best the moment it is assembled, while the chicken is still shatteringly crisp.

Expert Tips for a Standout Mary Brown’s Buffalo Mary

These are the small things that go a long way. I have learned a few of these the hard way so you do not have to.

• Pounding prevents dry chicken — An even 1/2-inch thickness means the breast cooks through at the same time the crust turns golden. Uneven chicken usually ends up overcooked on the thin side.
• Buttermilk time matters — Letting the chicken soak for at least 10 minutes tenderizes the meat. The acid in the buttermilk works quickly, and it also helps the flour adhere.
• Shake off excess flour — Press the chicken firmly into the flour, but give it a good shake afterward. Too much flour creates a thick, doughy coating instead of a crisp crust.
• Do not crowd the pot — Frying 2 pieces at a time keeps the oil temperature stable. Crowding drops the temperature, which makes the coating absorb oil and turn greasy.
• Check the internal temperature — Visual cues like golden-brown color are helpful, but a thermometer reading of 165°F / 74°C guarantees safe, fully cooked chicken.
• Sauce the chicken just before serving — Tossing it in the warm sauce too early means the crust softens. Keep the sauce warm, coat right before assembly, and serve fast.
• Use full-fat mayonnaise in the slaw — Low-fat versions are thinner and watery. The full-fat kind holds up against the hot chicken and keeps everything creamy.

Common Mistakes to Avoid

Frying can be intimidating, but most issues come down to a few repeatable mistakes. Here is what to watch out for.

• Skipping the thermometer — Guessing the oil temperature leads to undercooked chicken or burnt crust. The thermometer costs a few dollars and it takes all the guesswork away.
• Overcrowding the pot — Dropping all four pieces at once drops the oil temperature sharply. The coating absorbs more oil, leaving you with greasy, soggy chicken.
• Letting the sauce boil — The buffalo sauce should melt together gently, not come to a rolling boil. Boiling can cause the butter to separate and the sauce to look broken.
• Assembling too early — Build the sandwich only when you are ready to eat. The coleslaw and hot sauce will soften the crispy crust if it sits for more than a few minutes.
• Forgetting to shake off excess buttermilk — A wet breast carries too much liquid into the flour, creating clumps and a patchy crust. Let the excess drip off first.
• Using cold oil — If the oil is below 350°F / 175°C, the breading absorbs grease instead of frying crisp. Always wait for the temperature to come back up between batches.

Variations & Ways to Customize Mary Brown’s Buffalo Mary

This recipe is a great starting point. Here are a few ways to make it your own without overcomplicating things.

• Extra heat — Add more cayenne to the flour or a spoonful of your favorite hot sauce to the buttermilk brine. A drizzle of hot honey on top works too.
• Milder version — Cut the cayenne entirely and use just half the hot sauce in the buffalo sauce. You will still get flavor without the fire.
• Grilled option — Grilling the chicken instead of frying gives a lighter result. Marinate as directed, then cook over medium-high heat until it hits 165°F / 74°C.
• Crispy chicken tenders — Slice the breasts into strips before brining and frying. The cooking time drops to about 3-4 minutes per batch, and the strips make great appetizers.
• Swapped slaw — Use a pre-shredded slaw mix or swap the cabbage for shredded Brussels sprouts. Both hold up well against the hot sauce.
• Gluten-free adaptation — Swap the all-purpose flour for a 1:1 gluten-free flour blend. The crust will be slightly different but still crisp.

What to Serve With Mary Brown’s Buffalo Mary

This sandwich is a meal on its own, but the right side dishes round everything out. Here are some reliable pairings.

• Seasoned fries — A pile of crispy, salted fries is the classic Canadian chicken shop side. They soak up the extra sauce beautifully.
• Onion rings — Extra crunch that matches the texture of the sandwich. Go with the frozen or homemade ones, either works.
• Dill pickle spears — Keep playing on that briny contrast. Cold, crisp pickles refresh the palate between bites.
• Caesar salad — The creamy, garlicky dressing echoes the richness of the slaw without feeling repetitive.
• Coleslaw, extra batch — Double the slaw recipe and serve a bowl on the side. It is simple, but it works with almost everything.
• Iced tea or ginger ale — Something cold, slightly sweet, and carbonated helps cool the heat. Water works, but it is less fun.

Make-Ahead Instructions

You cannot fully assemble this sandwich in advance — the crispiness would suffer. But some of the components can absolutely be prepped ahead.

• Buffalo sauce can be made 1 week ahead — Store it in an airtight container in the refrigerator. Reheat gently over low heat, stirring until smooth.
• The coleslaw can be prepped 2 days ahead — It holds up fine in the fridge. Give it a stir before serving, and drain any excess liquid that collects at the bottom.
• Flour dredge can be measured in advance — Whisk the dry ingredients together and store in a sealed bag or container. When you are ready to fry, just pour it into a dish.
• Chicken can be brined earlier in the day — Keep it in the buttermilk in the fridge for up to a few hours before frying. That extra time only improves the tenderness.

Storage and Reheating

Fried chicken is best fresh, but leftovers can absolutely be saved. The key is using the right method to bring back that crunch.

Storage

• Assembled sandwiches — Refrigerate in an airtight container for up to 1 day. The bread will soften, so it is better to store components separately if you can.
• Fried chicken pieces — Keep them in an airtight container in the fridge for up to 2 days. Wrap them loosely so the crust does not steam itself soggy.
• Coleslaw separately — Store in a sealed container for up to 2 days. Stir before using and drain any pooling liquid.
• Buffalo sauce — Store in a jar or container for up to 1 week in the fridge. Reheat gently before using.

Reheating

• Oven method — Place chicken on a wire rack over a baking sheet and warm at 375°F / 190°C for 8-10 minutes. This restores most of the crispiness.
• Air fryer method — Heat at 350°F / 175°C for 5-6 minutes until hot and crisp. This is the fastest way to bring the crunch back.
• Stovetop method — For a smaller portion, warm in a skillet over medium heat for 2-3 minutes per side. Keep the oil minimal — just enough to prevent sticking.
• Avoid the microwave — It will turn the coating soft and chewy. If you truly have no other option, a short 30-second blast is better than nothing, but please try the oven or air fryer first.

Frequently Asked Questions

Can I freeze Mary Brown’s Buffalo Mary?

Freezing the fully assembled sandwich is not a good idea — the slaw will get watery and the bun will become mushy. You can freeze the fried, unsauced chicken in an airtight container for up to 2 months, then reheat in the oven or air fryer and coat with fresh sauce.

Can I use chicken thighs instead of breasts?

Yes, boneless skinless thighs work great. They are more forgiving and stay juicy even if you overcook them slightly. The cooking time stays about the same since you are still looking for an internal temperature of 165°F / 74°C.

How long does Mary Brown’s Buffalo Mary last in the fridge?

The fully assembled sandwich is best eaten within a day. Stored separately, the fried chicken lasts up to 2 days in the refrigerator, the coleslaw up to 2 days, and the buffalo sauce up to 1 week.

What is the best oil for deep frying?

Vegetable, canola, or peanut oil are all reliable choices because of their neutral flavor and high smoke point. Olive oil is not ideal here — it has a lower smoke point and a distinct taste that will compete with the seasoning.

Why is my breading falling off the chicken?

Usually it is a moisture problem. Be sure to shake off excess buttermilk before dredging, press the flour firmly onto the chicken, and let it sit on a wire rack for a few minutes before frying. That resting time lets the coating bond to the surface.

Final Words

Making this Mary Brown’s Buffalo Mary at home is easier than you might think, and the payoff is a sandwich that rivals anything from a drive-thru. The crispy crust, the spicy-sweet sauce, the cool slaw — every bite works together. Give it a try, and you will probably find yourself making it again before the week is over.
