Ingredients for baked mac and cheese recipe with dry mustard
Six ingredients create restaurant-quality mac and cheese with that signature nutty mustard depth.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lbs | Medium or fine elbow shape |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, aged 2+ years |
| Gruyère Cheese 🧀 | 1 cup | Shredded, nutty flavor |
| Cream Cheese 🧈 | 8 oz | Full-fat, room temperature |
| Heavy Cream 🥛 | 1 cup | 36% fat for richness |
| Whole Milk 🥛 | ½ cup | Warm for smooth sauce |
| Dry Mustard Powder 🌶️ | 1 tbsp | Yellow mustard preferred |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Butter 🧈 | 6 tbsp | Unsalted, melted |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Panko Breadcrumbs 🍞 | ¾ cup | Japanese-style for crisp |
| Salt 🧂 | 1 ½ tsp | Kosher salt, adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | ½ tsp | For breadcrumb seasoning |
The Gruyère is non-negotiable here—its nutty complexity pairs perfectly with the sharp cheddar. Grab a wedge from a specialty cheese shop if you can; pre-shredded loses flavor fast. For the mustard, yellow mustard powder gives the best tang without bitterness. Penzeys or bulk spice bins are great sources. The panko breadcrumbs should be Japanese-style—they stay crisp longer than regular breadcrumbs. If you can't find it, toast regular breadcrumbs for 5 minutes to crisp them up yourself.
No Gruyère? Comté or aged Gouda works in a pinch, but the flavor won't be identical. Short on heavy cream? Half-and-half plus extra butter gets you close. The flour is just for thickening—if your sauce is too thin, add another tablespoon. For the breadcrumb topping, add a pinch of smoked paprika if you want extra depth. The garlic powder in the topping is optional but recommended—it ties everything together beautifully.
This keeps 3-4 days in the fridge, though it's best eaten fresh. For make-ahead prep, assemble the dish (without baking) and refrigerate for up to 24 hours. The breadcrumb topping stays crispy for about 20 minutes after baking, so serve immediately. Leftovers reheat best covered at 350°F for 10 minutes—add a splash of milk to prevent drying.

Step-by-step instructions for baked mac and cheese with dry mustard
Here's how to create a rich, nutty mac and cheese with a perfectly crispy breadcrumb crown.
Cook the Elbow Macaroni to Al Dente Perfection
Bring a large pot of water to a rolling boil and add the 1.5 lbs elbow macaroni. Season generously with 1.5 teaspoons salt—the water should taste like seawater. Cook until 1 minute shy of package directions for al dente texture. This slight undercooking prevents mushiness when baked.
Drain the pasta and return it to the pot. Immediately add 2 tablespoons butter and toss to coat. This prevents sticking and adds richness. Keep the pot over low heat while you prepare the cheese sauce—don't let the pasta dry out.
Create the Nutty Cheese Sauce with Mustard Depth
In a large saucepan over medium heat, melt 6 tablespoons butter until foaming. Whisk in 2 tablespoons all-purpose flour and cook for 1-2 minutes until golden. This creates a roux that thickens the sauce beautifully.
Gradually whisk in 1 cup heavy cream and 0.5 cup warm whole milk, ensuring no lumps form. Add the 2 cups sharp cheddar cheese, 1 cup gruyère cheese, and 8 oz cream cheese all at once. Stir constantly until fully melted and smooth. Remove from heat and whisk in 1 tablespoon dry mustard powder and 3 minced garlic cloves. This mustard gives the classic tangy depth that elevates homemade mac and cheese.
Combine Pasta and Sauce for Maximum Flavor
Pour the cheese sauce over the cooked macaroni in the pot. Add 0.5 teaspoon black pepper and toss thoroughly until every strand is coated. The sauce should be thick enough to cling but still slightly loose—this ensures creamy texture after baking. If needed, add 1-2 tablespoons pasta water to loosen.
Transfer the mixture to a 9x13-inch baking dish, spreading it evenly. This size allows for proper browning and crispy edges. Press down gently with a spatula to compact the macaroni—this prevents excessive spreading during baking.
Top with Seasoned Breadcrumbs for Crispy Perfection
In a small bowl, combine 0.75 cup panko breadcrumbs, 0.5 teaspoon garlic powder, and 0.5 teaspoon black pepper. Sprinkle evenly over the macaroni, pressing down lightly to adhere. This creates that coveted crispy crown that contrasts perfectly with the creamy interior.
Bake at 375°F for 25-30 minutes until the top is deep golden brown and bubbly. The edges should be crispy while the center remains creamy. If the top browns too quickly, loosely cover with foil for the last 5 minutes to prevent burning.
Rest and Serve with Perfect Texture
Remove from the oven and let rest for 10 minutes before serving. This resting period allows the sauce to set slightly, preventing a runny texture. The breadcrumb topping should be crispy and golden, while the interior remains creamy and rich with that signature nutty depth from the gruyère and mustard.
Cut into squares and serve immediately. The contrast of crispy topping and velvety cheese will make this your new go-to mac and cheese recipe.
Pro Tips For Making Baked Mac And Cheese Recipe With Dry Mustard
- CRANK THE OVEN TO 375°F: I used to bake this at 350°F like every other recipe, but 375°F gets you a golden crust faster without drying out the middle. The mustard needs heat to bloom properly, so don’t skimp—this is where the tang really shines.
- GRATE CHEESE FRESH—NO EXCUSES: Pre-shredded cheese has anti-caking agents that make the sauce grainy. Grab a box of sharp cheddar and Gruyère, grate them yourself, and toss them into the sauce while it’s still hot. The texture difference is night and day.
- DON’T DRAIN THE PASTA: That starchy water is your glue—it helps the cheese sauce cling to the noodles. Cook the elbows in salted water, then transfer them straight to the baking dish with a splash of that liquid. Yes, it’ll look messy at first, but it’s the thing that matters most.
- STIR IN THE MUSTARD LAST: Mix the dry mustard powder into the cream cheese and heavy cream after the sauce is off the heat. If you add it too early, it’ll cook out and lose its sharp kick. A teaspoon is enough—any more, and you’ll regret it.
Storing and reheating this dish
Fridge Storage Tips
Store your baked mac and cheese in an airtight container for up to 4 days in the fridge. The key is letting it cool completely before covering—this prevents condensation that can make the breadcrumb topping soggy.
I use glass containers with snap-on lids because they keep the flavors fresh longer than plastic. 🥫
Freezer Prep Guide
For freezing, assemble the dish (without baking) and refrigerate overnight. This helps the flavors meld. Then bake it fresh when ready, or freeze the baked version for up to 3 months.
Wrap tightly in plastic wrap followed by aluminum foil to prevent freezer burn. When reheating from frozen, add 1-2 tablespoons milk to restore creaminess.
Reheating for Best Texture
For stovetop reheating, cover the mac and cheese with a damp paper towel and warm on low heat for 10-15 minutes. The steam helps restore the crispy topping.
For oven reheating, bake at 350°F for 15-20 minutes covered with foil, then broil for 2-3 minutes to crisp the top again. Microwave reheating works in a pinch but tends to make the breadcrumbs rubbery.
Reviving the Crisp
If the breadcrumb topping loses its crunch after reheating, sprinkle fresh panko breadcrumbs on top and broil for 1-2 minutes until golden. This quick fix adds that satisfying texture contrast.
For extra flavor, mix the breadcrumbs with a pinch of garlic powder before broiling. The mustard flavor remains intact through reheating, so you won't lose that signature tang.
Portioning for Meal Prep
Divide into individual portions before freezing or storing. I like using quart-sized freezer bags for single servings—they're easy to reheat and take up less space. Label each bag with the date to track freshness.
When reheating individual portions, use 30% power in the microwave for 1-2 minutes with a splash of milk to maintain creaminess. 💡
Make-Ahead Baking Hack
Prepare the baked mac and cheese completely (including baking) up to 2 days ahead and refrigerate. When ready to serve, simply reheat in the oven at 350°F for 10 minutes to revive the crispy topping.
This works especially well for large gatherings—just bake once and serve over multiple days. The mustard flavor actually develops more depth when stored, making leftovers taste even better!

Frequently asked questions
Why does this recipe use dry mustard instead of prepared mustard?
Dry mustard powder delivers a more controlled, subtle tang without the sharpness or moisture of prepared mustard. The 1 tablespoon adds just enough depth to complement the cheeses, while avoiding the risk of making the sauce too thin. Prepared mustard could also introduce unwanted moisture that weakens the breadcrumb topping.
Can I substitute Gruyère with another cheese?
Yes! For the nutty depth, try Comté or aged Gouda—they'll work in a pinch. If you want a sharper flavor, swap in Parmesan (use ½ cup instead of the full cup). The mustard still gives that signature tang, but the overall flavor profile will shift slightly. Avoid pre-shredded cheeses—they contain anti-caking agents that make the sauce grainy.
How do I fix a runny mac and cheese after baking?
If your mac and cheese is too loose, sprinkle extra breadcrumbs on top and broil for 2-3 minutes to crisp them. For a thicker sauce, mix 1 tablespoon cornstarch with 1 tablespoon cold water, stir into the sauce, and bake for an additional 5 minutes. The mustard powder helps stabilize the sauce, but sometimes the cream cheese can still make it too soft. Always press the pasta down firmly in the baking dish!
What’s the secret to the perfect crispy breadcrumb topping?
Use Japanese-style panko (not regular breadcrumbs) and press it firmly onto the mac and cheese before baking. Toast the panko in a dry pan for 3-4 minutes before adding it to the dish for extra crunch. The key is baking at 375°F until the top is deep golden brown—don’t skip the 10-minute rest after baking, or the topping will soften.
Can I make this mac and cheese ahead of time?
Assemble the dish (without baking) up to 24 hours ahead and refrigerate. When ready to bake, add 5-10 minutes to the baking time to account for the cold start. For the best texture, bake it fresh the day of serving. If you bake it ahead, store it covered at room temperature for up to 2 hours—the mustard flavor actually intensifies slightly as it sits!
