Mastro’s Mac and Cheese Recipe: Steakhouse-Style Creamy Decadence

This mac and cheese delivers steakhouse-quality results with a creamy texture that clings perfectly to every noodle. I developed this recipe after too many restaurant versions left me wanting more at home.

The secret is a combination of sharp cheddar and Gruyère, melted into a velvety cheese sauce that never separates. A touch of mustard powder enhances the cheesiness without overpowering the dish.

What you get is elbow macaroni coated in a sauce so rich and creamy it feels indulgent. The top develops a golden crust that adds textural contrast to the smooth interior.

This side dish transforms any meal into a special occasion. Here’s how to make it at home with professional results every time.

Ingredients for Mastro’s Mac and Cheese

Steakhouse quality starts with sharp cheddar, Gruyère, and a few pantry staples for that signature creamy sauce.

The cheese is non-negotiable here. Sharp cheddar and Gruyère give that restaurant depth—skip the pre-shredded stuff (it’s coated in anti-caking agents). I grab blocks from Whole Foods or Trader Joe’s and grate them fresh. The Gruyère melts like a dream, while the cheddar brings the tang. For the milk and cream, full-fat only—this isn’t the time for skim.

No Gruyère? Fontina or Monterey Jack work in a pinch, but the flavor won’t be as complex. Mustard powder is key for that cheesy punch—don’t swap it for Dijon. The panko topping can be regular breadcrumbs if that’s what’s in the pantry (just toast them longer). And if you’re feeling fancy, a pinch of nutmeg in the sauce adds warmth.

This mac reheats like a champ—cover with foil and warm at 350°F until bubbly. Keeps for 3-4 days in the fridge, though it’s best fresh. Freeze without the topping for up to 2 months, then add panko and bake straight from frozen.

Step-by-Step Instructions for Steakhouse-Style Mac and Cheese

Here’s how I nail that velvety, restaurant-quality texture every single time.

Step 1: Cook the Elbow Macaroni to Al Dente

Bring a large pot of salted water to a rolling boil. Add the 12 oz Elbow Macaroni and cook for 1 minute less than the package instructions—you want it just shy of al dente. This prevents it from turning mushy when baked later.

Drain the pasta in a colander and immediately rinse under cold water to stop the cooking process. I shake off as much excess water as possible, then let it sit in the colander for 5 minutes to drain completely. A dry surface ensures the sauce clings properly instead of pooling at the bottom.

Step 2: Craft a Silky Cheese Sauce with the Roux

In a heavy saucepan over medium heat, melt 0.5 cup Unsalted Butter. Once foaming subsides, whisk in the 0.25 cup All-Purpose Flour to form a smooth roux. Cook for 1-2 minutes until the mixture turns a pale golden color and smells lightly nutty—this removes the raw flour taste.

Gradually whisk in the 2 cups Whole Milk and 1 cup Heavy Cream, ensuring no lumps form. Stir in the 1 tsp Mustard Powder, 0.5 tsp Garlic Powder, 1 tsp Salt, and 0.5 tsp Black Pepper. Bring to a gentle simmer, then reduce heat to low and cook for 3-4 minutes until the sauce thickens enough to coat the back of a spoon.

Step 3: Incorporate the Cheeses for Maximum Creaminess

Remove the saucepan from heat and stir in the 2 cups Sharp Cheddar Cheese and 1.5 cups Gruyère Cheese until completely melted and smooth. I add the cheeses in two batches to prevent clumping, stirring constantly until each addition is fully incorporated.

Fold the cooked elbow macaroni into the sauce, ensuring every piece is evenly coated. The sauce should be thick but still pourable—if it’s too tight, stir in a splash of warm milk to loosen. This is where the magic happens; the combination of sharp cheddar and gruyère creates that signature steakhouse depth.

Step 4: Top with Panko and Parmesan for a Golden Crust

Transfer the mac and cheese to a lightly greased baking dish. In a small bowl, mix the 0.5 cup Panko Breadcrumbs with the 0.5 cup Parmesan Cheese. Sprinkle this mixture evenly over the top, pressing down lightly to adhere.

Bake at 375°F for 15-20 minutes until the topping is golden brown and the edges are bubbling. For extra browning, broil for 1-2 minutes at the end, but keep a close eye to avoid burning. Let it rest for 5 minutes before serving to allow the sauce to set slightly.

Health Benefits of These Flavors

Calcium Rich Comfort

This dish delivers a serious calcium boost from the sharp cheddar and Gruyère—just 1 cup of this mac provides about 30% of your daily calcium needs. The whole milk and heavy cream add even more of this bone-strengthening mineral. 💪

The elbow macaroni offers complex carbohydrates for sustained energy, while the fats from the cheese and cream help keep you full longer. I find this dish keeps me powered through busy afternoons in my Boston kitchen.

Dairy products are naturally rich in vitamin B12, and this recipe is no exception. The Gruyère and Parmesan contribute significantly to your daily needs, supporting nerve function and red blood cell production.
