Baked Macaroni and Cheese Recipe with Dry Mustard: Sharp Heat and Silky Stovetop Base

This baked macaroni and cheese recipe with dry mustard delivers the perfect balance of sharp heat and creamy richness. The secret lies in a silky stovetop base where dry mustard adds depth without overpowering the cheese.

I've perfected this technique to ensure every bite is tender, flavorful, and just slightly tangy—a far cry from the overly sweet or bland versions you might find elsewhere.

The dry mustard transforms this dish by cutting through the richness of the cheese sauce, creating a complex flavor profile that lingers on the palate. We start with a proper roux to build a smooth, velvety base before adding the cheese blend, ensuring no lumps or separation.

The baking step then develops a golden, slightly crispy top while keeping the pasta perfectly tender.

What you'll end up with is a dish that's elegant enough for dinner parties but simple enough for a weeknight. The mustard's sharp notes complement the creamy cheese, while the baked crust adds satisfying texture. This recipe serves six comfortably, making it ideal for gatherings or meal prep.

Pair it with roasted vegetables or a simple green salad for a complete meal. The versatility of this baked mac and cheese means it works as a main dish or even as a hearty side. Here's how to make it perfectly every time.

Ingredients for baked macaroni and cheese recipe with dry mustard

Six ingredients transform into a restaurant-quality baked mac and cheese with sharp mustard depth.

The dry mustard is non-negotiable here—Penzeys or Bob's Red Mill brands deliver the best sharpness. For the cheese blend, Kraft Yellow American and sharp cheddar create that iconic tangy-sweet balance. The elbow macaroni holds sauce better than other shapes, so don't substitute. Butter must be cold for a proper roux—European-style butter like Plugrá works best if you want extra richness. Most grocery stores carry all these staples, but specialty shops have better cheese selections.

No dry mustard? Dijon mustard at half the amount works in a pinch, but the flavor won't be identical. Substituting milk? Whole milk is essential—skim or almond milk will make the sauce separate. For the breadcrumb topping, panko plus a pinch of garlic powder adds extra flavor. Cheese getting clumpy? Use a food processor for perfectly shredded cheese. The parsley is optional but adds freshness—skip if you're sensitive to strong flavors.

This reheats beautifully—5 minutes at 350°F restores that creamy texture. Keeps 4-5 days in the fridge, freezes for 3 months if portioned in airtight containers. For meal prep, bake individual ramekins—they reheat perfectly. The breadcrumb topping stays crispy when reheated if you cover it with foil during the last 2 minutes of baking.

Step-by-step instructions for baked macaroni and cheese with dry mustard

Here's how to build a rich, sharp-flavored mac and cheese with a crispy breadcrumb topping.

Bring a large pot of water to a rolling boil and add 1.5 lb elbow macaroni. Add 1.5 tsp kosher salt to the water—it should taste like the ocean. Cook for 11-12 minutes until the pasta is al dente, with a slight bite remaining. You'll finish cooking it in the oven, so don't overcook.

Drain the pasta in a colander and rinse briefly with cold water to stop the cooking process. Shake off any excess water and return the pasta to the pot. This step prevents the sauce from becoming watery when combined later. Keep the pot nearby as you'll need it for the roux.

In the same pot, melt 0.5 cup unsalted butter over medium heat until it foams. Add 0.5 cup all-purpose flour and whisk constantly for 2-3 minutes until the mixture forms a smooth, pale roux. This should look like wet sandpaper—no lumps allowed.

Gradually whisk in 2 cups whole milk, adding it slowly to prevent lumps from forming. Continue whisking until the mixture thickens enough to coat the back of a spoon, about 5-7 minutes. Remove from heat and stir in 2 cups yellow American cheese, 1.5 cups sharp cheddar cheese, 1.5 tsp dry mustard powder, 0.5 tsp black pepper, and 0.5 tsp garlic powder. Stir until completely melted and smooth.

Add the drained elbow macaroni to the cheese sauce and stir gently to coat each strand evenly. The sauce should cling to the pasta without pooling at the bottom. If it's too thick, add 1-2 tablespoons of reserved pasta water to loosen it. This step ensures every bite is creamy and flavorful.

Transfer the macaroni and cheese mixture to a 9x13-inch baking dish, spreading it evenly. The dish should be about ¾ full—this allows room for the breadcrumb topping to crisp without overflowing. Preheat your oven to 375°F while you prepare the topping.

In a small bowl, combine 0.25 cup breadcrumbs, 1 tbsp extra-virgin olive oil, and 0.25 cup chopped fresh parsley. Mix until the breadcrumbs are evenly moistened but not soggy. Sprinkle this mixture evenly over the top of the macaroni and cheese, pressing down gently with a spatula to help it adhere.

Bake uncovered for 20-25 minutes until the top is golden brown and the edges bubble slightly. The cheese should be fully melted and the breadcrumbs should be crispy. If the top browns too quickly, tent loosely with foil to prevent burning while the center finishes cooking.

Remove the baking dish from the oven and let it rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly, making it easier to slice and serve. The dish will be hot, so use oven mitts when handling it.

Cut into squares and serve immediately. The sharp cheddar and dry mustard create a perfect balance of richness and tang, while the crispy breadcrumb topping adds texture. The stovetop base ensures a silky texture without being overly creamy, making each bite satisfying and well-rounded.

Creative variations of these flavors

Spicy Heat Boost

For an extra kick, stir in ½ tsp cayenne pepper or 1 tsp smoked paprika with the dry mustard. I like adding ½ tsp chipotle powder for a smoky depth that pairs beautifully with the sharp cheddar.

If you want to go bold, a pinch of cayenne at the table lets everyone customize their heat. 🌶️

Creamy Potato Twist

Add 1 cup diced Yukon Gold potatoes to the pasta water and cook them until tender. Drain with the pasta, then fold into the cheese sauce. The potatoes absorb the mustard-infused cheese beautifully, adding a comforting, hearty texture. This variation works especially well for larger gatherings.

Vegetable-Packed Version

Stir in 1 cup steamed broccoli florets or ½ cup sautéed mushrooms when combining the pasta and sauce. The vegetables add color and nutrition without overpowering the mustard-cheese flavor. For extra richness, fold in ½ cup cooked bacon bits or crumbled pancetta.

Crispy Top Variations

Swap the breadcrumb topping for crushed Ritz crackers mixed with 2 tbsp melted butter for a buttery crunch. For a cheesy crust, sprinkle ½ cup shredded mozzarella on top before baking. Both options create a satisfying contrast to the creamy interior.

Breakfast Mac and Cheese

Transform this into a breakfast dish by stirring in 2 eggs and ½ cup shredded sharp cheddar after removing it from the oven. The eggs create a custard-like texture that's perfect for brunch. Top with chives or green onions for a fresh finish.

Mustard-Free Adaptation

If you're avoiding mustard, replace the 1.5 tsp dry mustard with 1 tsp white miso paste for umami depth or ½ tsp onion powder for a sweeter note. The miso adds complexity while keeping the dish rich and satisfying. Both alternatives work well without altering the baking process.
