Longhorn Steakhouse Mac and Cheese Recipe

This Longhorn Steakhouse Mac Cheese is a rich, creamy side dish that rivals the restaurant version. It combines a velvety cheese sauce made from sharp cheddar, Monterey Jack, and Parmesan with a crispy, buttery panko topping.

You can have this on the table in 40 minutes, and it is beginner-friendly enough for a weeknight yet impressive for holidays or potlucks. The only tricky part is getting the cheese sauce smooth, but that is easier than it sounds.

Why You’ll Love This Recipe

• Restaurant quality at home — This tastes just like the steakhouse version without the wait or the bill.
• Perfectly creamy sauce — A blend of three cheeses and a simple roux guarantees a smooth, never-grainy texture.
• Crispy topping in minutes — The panko breadcrumb crust browns beautifully under the broiler for that signature crunch.

What Makes This Recipe Special

This dish stands out because of the careful cheese blend and the Dijon mustard trick that keeps the sauce emulsified. Sharp cheddar brings tang, Monterey Jack adds melt, and Parmesan contributes a nutty depth. The result is a mac and cheese that is decadently creamy on the inside with a crisp, golden crust on top — perfect for any occasion.

Ingredients You’ll Need

Here is everything you need to make this copycat recipe. Use fresh ingredients for the best texture and flavor.

For the Pasta

• 8 oz dried elbow macaroni (about 2 cups) — Classic elbows hold the sauce well. Cook them al dente so they stay firm after baking.

For the Cheese Sauce

• 2 tablespoons unsalted butter — Forms the base of the roux for thickening.
• 2 tablespoons all-purpose flour — Cooked with the butter to eliminate raw taste.
• 1 1/2 cups whole milk — Full fat gives the creamiest sauce.
• 1/2 cup heavy cream — Adds richness that milk alone cannot match.
• 1 teaspoon kosher salt — Season the sauce slightly well since the pasta absorbs salt.
• 1/2 teaspoon freshly ground black pepper — Freshly ground adds more depth than pre-ground.
• 1/2 teaspoon garlic powder — A subtle savory note, not overpowering.
• 1/4 teaspoon smoked paprika (optional) — Adds a gentle smokiness that works beautifully.
• 1/4 teaspoon Dijon mustard — This prevents the cheese from turning grainy during melting.
• 6 oz (1 1/2 cups) sharp cheddar cheese, shredded — Grate it fresh from a block; pre-shredded has anti-caking agents that can ruin the sauce.
• 4 oz (1 cup) Monterey Jack cheese, shredded — Melts beautifully for extra creaminess.
• 2 oz (1/2 cup) Parmesan cheese, finely grated — Adds a salty, nutty finish.

For the Topping

• 1/2 cup panko breadcrumbs — Bigger flakes yield a crunchier crust than regular breadcrumbs.
• 1 1/2 tablespoons unsalted butter, melted — Coats the panko for even browning.

Equipment Needed

• Large pot (at least 3-quart) — For cooking pasta and making the sauce. A heavy-bottomed Dutch oven works great.
• 2-quart baking dish (8×8 inch or similar) — Holds the assembled mac and cheese. Glass, ceramic, or metal all work.
• Whisk — Essential for a lump-free roux and smooth sauce.
• Rubber spatula or wooden spoon — Gentle folding prevents breaking the cheese sauce.
• Small bowl — For mixing the panko and melted butter.

Instructions to Prepare Longhorn Steakhouse Mac Cheese

Follow these steps closely for the creamiest, crispiest result. The process moves quickly once the pasta is ready.

• Preheat and cook pasta — Preheat oven to 375°F (190°C). Bring salted water to a boil, cook elbows al dente (1 minute less than package), drain, and set aside. Do not rinse.
• Make the roux — In a large pot over medium heat, melt butter. Add flour and whisk constantly for 1-2 minutes until pale golden and nutty. This removes raw flour taste.
• Add milk and cream — Slowly pour in milk and cream while whisking vigorously to prevent lumps. Reduce heat to medium-low and cook, stirring, until it thickens enough to coat a spoon, about 3-5 minutes.
• Season the base — Stir in salt, pepper, garlic powder, smoked paprika (if using), and Dijon mustard. Taste and adjust salt — it should be slightly strong since pasta absorbs some.
• Melt the cheeses — Remove pot from heat. Add cheddar and Monterey Jack in two batches, stirring gently until fully melted. Then stir in Parmesan until just combined. Do not overmix.
• Combine pasta and sauce — Add cooked elbows to the sauce and fold gently until every piece is coated. Transfer to a baking dish and spread evenly.
• Add topping — Toss panko with melted butter until moistened. Sprinkle evenly over the mac and cheese.
• Bake and serve — Bake on upper rack for 10-14 minutes until bubbling and golden. If topping needs more color, broil 1-2 minutes. Let rest 5 minutes before serving.

Expert Tips for a Standout Longhorn Steakhouse Mac Cheese

• Grate your own cheese — Pre-shredded cheese contains cellulose that prevents smooth melting. Freshly grated cheese guarantees a silky sauce every time.
• Cook pasta 1 minute under — Al dente pasta holds its shape during baking and absorbs sauce without turning mushy.
• Remove pot from heat before adding cheese — High heat causes cheese to separate and turn gritty. The residual heat is enough to melt it smoothly.
• Let the dish rest after baking — That 5-minute rest allows the sauce to set slightly, so servings hold together better and stay creamy.
• Use a heavy-bottomed pot — It distributes heat evenly and prevents the roux or sauce from scorching.
• Do not skip the Dijon mustard — It acts as an emulsifier, keeping the cheese sauce stable and smooth even during reheating.

Common Mistakes to Avoid

• Overcooking the pasta — Mushy pasta loses structure in the oven. Cook to al dente for the best texture.
• Skipping the roux cooking time — A raw flour taste ruins the sauce. Cook the roux until it smells nutty and turns pale golden.
• Using pre-shredded cheese — Anti-caking agents prevent smooth melting, leading to a grainy sauce. always shred your own.
• Adding cheese over high heat — High heat causes the proteins in cheese to seize, making the sauce gritty. Always remove the pot from the burner first.
• Overmixing the sauce — Stirring too vigorously at any stage can break the emulsion. Fold gently with a spatula.

Variations & Ways to Customize Longhorn Steakhouse Mac Cheese

• Add cooked bacon — Crumble 4-5 slices of crispy bacon and fold it in with the pasta for a smoky, salty crunch.
• Swap the cheeses — Replace Monterey Jack with Gruyère for a nuttier flavor, or use smoked gouda for extra smokiness.
• Make it spicy — Stir in 1/2 teaspoon of cayenne pepper or a diced jalapeño with the seasonings for heat.
• Add vegetables — Fold in steamed broccoli, roasted cauliflower, or sautéed mushrooms before baking for a heartier dish.
• Use a different pasta shape — Cavatappi, shells, or rotini all work well since their curves hold the sauce nicely.
• Make extra topping — Double the panko-butter mixture for a thicker, crunchier crust if you like a lot of crunch.

What to Serve With Longhorn Steakhouse Mac Cheese

This rich side pairs wonderfully with simple proteins and bright sides. Here are some of my favorite combinations.

• Grilled steak — The classic pairing. A medium-rare ribeye or sirloin balances the creamy pasta perfectly.
• Roasted chicken — Juicy roast chicken with crispy skin cuts through the richness of the cheese sauce.
• Garlic green beans — A bright, crunchy vegetable side adds freshness and color to the plate.
• Caesar salad — The tangy dressing and crisp romaine provide a nice contrast to the creamy mac and cheese.
• Crusty bread — Use it to soak up leftover cheese sauce at the bottom of the dish.
• Red wine — A medium-bodied red like Merlot or Zinfandel complements the cheddar and Parmesan nicely.

Make-Ahead Instructions

• Assemble without topping — Prepare the mac and cheese through step 6, transfer to the baking dish, and let it cool completely. Cover and refrigerate for up to 2 days.
• Freeze before baking — Assemble without breadcrumbs, wrap tightly in plastic wrap then foil, and freeze for up to 2 months. Thaw overnight in the fridge before adding topping and baking.
• Prepare the topping separately — Store the panko-butter mixture in an airtight container in the fridge for up to 3 days. Sprinkle it on just before baking so it stays crisp.
• Bake directly from frozen — If you forgot to thaw, bake covered with foil at 350°F for 20 minutes, then uncover and bake 10 more minutes until bubbly.

Storage and Reheating

Storage

• Airtight container — Transfer leftovers to a container with a tight lid. They will keep in the fridge for up to 4 days.
• Cool first — Let the mac and cheese cool completely before storing to prevent condensation from making the topping soggy.
• Freeze for longer storage — Place in a freezer-safe container, press out excess air, and freeze for up to 2 months. Thaw in the fridge overnight.

Reheating

• Oven method — Reheat in a 350°F (177°C) oven, covered with foil, for 10-15 minutes. Add a splash of milk if the sauce seems dry.
• Microwave method — Place in a microwave-safe dish and heat at 70% power in 30-second bursts, stirring between each, until hot. Add a splash of milk as needed.
• Stovetop method — Reheat in a saucepan over low heat, stirring gently and adding milk a tablespoon at a time to restore creaminess.
• Air fryer method — Reheat at 350°F for 5-7 minutes in a small oven-safe dish. The topping will crisp up again nicely.

Frequently Asked Questions

Can I use pre-shredded cheese for Longhorn Steakhouse Mac Cheese?

I do not recommend it. Pre-shredded cheese has anti-caking agents that prevent smooth melting, leaving a gritty sauce. Grate your own cheddar, Monterey Jack, and Parmesan for the creamiest result.

Can I freeze Longhorn Steakhouse Mac Cheese?

Yes, but for the best texture, assemble the dish without the breadcrumb topping, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge, then add fresh panko topping and bake as directed.

How do I keep the cheese sauce from separating?

Remove the pot from heat before adding cheese, and stir gently. The Dijon mustard in the recipe also helps emulsify the sauce so it stays smooth and glossy.

Can I make this gluten-free?

Yes. Substitute the all-purpose flour with a gluten-free all-purpose blend (one that contains xanthan gum) for the roux. Use gluten-free panko breadcrumbs for the topping.

Why did my breadcrumb topping burn?

If the topping browns too quickly, cover the dish loosely with foil for the first 8 minutes of baking, then remove it for the final few minutes. Also, keep an eye on it during broiling — it only takes 1-2 minutes.

How long does Longhorn Steakhouse Mac Cheese last in the fridge?

Stored in an airtight container, it stays fresh for up to 4 days. The topping will soften over time, but reheating in the oven or air fryer can help crisp it back up.

Final Words

This Longhorn Steakhouse Mac Cheese delivers everything you love about the restaurant version — creamy, cheesy, and topped with a perfect golden crust. It is a side dish that steals the show every time. Give it a try, and you will see why it is a favorite.
