The Ultimate Baked Mac and Cheese with Three-Cheese Mornay
This baked mac and cheese features a velvety sharp cheddar and gruyère mornay sauce, al dente elbow pasta, and a buttery panko crust that shatters with every bite.
There is no comfort food more essential than a truly great baked mac and cheese. While many recipes rely on a heavy, leaden sauce, this version focuses on a silky mornay made with three distinct cheeses to ensure a balance of sharp flavor and superior meltability.
The secret to this creamy baked macaroni and cheese is the addition of a small amount of American cheese. It acts as a natural emulsifier, keeping the sharp cheddar and nutty gruyère from breaking into an oily mess in the oven. The result is a texture that mimics the best southern baked mac and cheese traditions while maintaining a sophisticated, complex flavor profile.
Finally, we top the dish with a generous layer of buttered panko breadcrumbs. Unlike traditional soft toppings, this crust provides a necessary textural contrast to the tender noodles underneath, giving you that satisfying crunch in every single forkful.
Ingredients
The Pasta
- 1 lb (450g) elbow macaroni
- 1 tbsp kosher salt for pasta water
The Three-Cheese Sauce
- 4 tbsp (56g) unsalted butter
- 1/4 cup (30g) all-purpose flour
- 3 cups (710ml) whole milk, room temperature
- 1 cup (240ml) heavy cream
- 8 oz (225g) extra-sharp yellow cheddar, freshly grated
- 6 oz (170g) gruyère cheese, freshly grated
- 2 oz (55g) high-quality white American cheese, chopped (from the deli counter)
- 1 tsp Dijon mustard
- 1/2 tsp garlic powder
- 1/4 tsp smoked paprika
- 1/4 tsp cayenne pepper (optional)
- Kosher salt and black pepper to taste
The Panko Crust
- 1 cup (60g) panko breadcrumbs
- 2 tbsp (28g) unsalted butter, melted
- 1/4 cup (25g) grated parmesan cheese
- 1/2 tsp dried parsley
Instructions
- 1
Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish with butter.
- 2
Boil the elbow macaroni in a large pot of salted water for 2 minutes less than the package directions for al dente; the pasta will finish cooking in the oven.
- 3
Drain the pasta and set aside, but do not rinse it—the starch helps the cheese sauce cling to the noodles.
- 4
Melt 4 tablespoons of butter in a large saucepan or Dutch oven over medium heat.
- 5
Whisk in the flour and cook for 1-2 minutes until the raw flour smell is gone and the roux is slightly golden.
- 6
Slowly stream in the milk and heavy cream while whisking constantly to prevent lumps; simmer until the sauce is thick enough to coat the back of a spoon.
- 7
Remove the pot from the heat and stir in the Dijon, garlic powder, paprika, and cayenne.
- 8
Add the grated cheddar, gruyère, and American cheese one handful at a time, stirring until the sauce is completely smooth and velvety.
- 9
Fold the cooked macaroni into the cheese sauce until every noodle is submerged, then pour the mixture into the prepared baking dish.
- 10
Toss the panko breadcrumbs with melted butter, parmesan, and parsley in a small bowl and sprinkle evenly over the mac.
- 11
Bake for 20-25 minutes until the sauce is bubbling at the edges and the panko topping is deeply golden brown.
- 12
Let the dish rest for 10 minutes before serving to allow the sauce to set slightly.

Tips
- → Always grate your own cheese from a block. Pre-shredded cheeses are coated in potato starch or cellulose to prevent clumping, which will make your sauce grainy.
- → Do not overcook the pasta during the boiling phase. Aim for a 'bitey' texture so it doesn't turn into mush after 20 minutes in the oven.
- → Room temperature milk and cream incorporate much more easily into the roux, resulting in a smoother mornay sauce.
- → If you prefer a more traditional southern baked mac and cheese experience, stir in a beaten egg to the cooled cheese sauce before adding the pasta for a firmer, custard-like set.
FAQ
Why does my baked mac and cheese turn out dry?
Dryness is usually caused by two things: overcooking the pasta in the water (it absorbs too much sauce later) or not having enough sauce-to-pasta ratio. This recipe uses a high volume of mornay to ensure it stays creamy after baking.
Can I make this recipe ahead of time?
Yes, you can assemble the mac and cheese, let it cool, and refrigerate it. However, do not add the panko topping until you are ready to bake, and add 10-15 minutes to the oven time if baking straight from the fridge.
How do I keep the cheese sauce from breaking?
The addition of American cheese provides sodium citrate, which acts as an emulsifier. Also, ensure you remove the sauce from the heat before adding the shredded cheese so the fats don't separate.
What is the best pasta shape for baked mac?
Elbow macaroni is classic because the hollow tubes trap the sauce, but cavatappi (corkscrew) or pipe rigate are excellent alternatives for holding onto a thick mornay.
