Ingredients for baked mac and cheese recipe with mustard powder
Sharp cheddar, Gruyère, and cream cheese blend into velvety sauce with mustard powder's tangy kick.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 12 oz | Uncooked, medium or elbow shape |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | 1 cup | Shredded, aged for best flavor |
| Cream Cheese 🧈 | 8 oz | Full-fat, room temperature |
| Mustard Powder 🌶️ | 1 tbsp | Yellow or Dijon preferred |
| Heavy Cream 🥛 | 1 cup | Whole milk fat for richness |
| Whole Milk 🥛 | 1 cup | Room temperature for smooth sauce |
| Unsalted Butter 🧈 | 4 tbsp | Cold, cut into small cubes |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, for topping |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |

The cheeses are the heart of this dish, so don’t skimp on quality. Sharp white cheddar from a block (like Cabot or Tillamook) melts smoother than pre-shredded, and Gruyère adds nutty depth—look for it in the specialty cheese section at Whole Foods or Trader Joe's. Cream cheese should be full-fat (Philadelphia is the gold standard) and room temperature for a silky sauce. The mustard powder? Penzeys or Diamond Crystal are my go-tos—avoid the weak powdered mustard from the spice aisle. For the pasta, elbow macaroni holds sauce best, but any short shape works.
No sharp cheddar? Extra-sharp cheddar at half the amount works in a pinch, but the flavor won’t be as bright. Substituting Gruyère? Parmigiano-Reggiano or Emmental are solid swaps, though Gruyère’s melt is unmatched. Short on heavy cream? Full-fat coconut milk adds richness (though it’ll taste coconutty). The flour is for thickening—if your sauce is too thin, add another tablespoon. For the breadcrumbs, Japanese panko is non-negotiable for that perfect crunch, but regular breadcrumbs toasted in the oven work too. And if you’re gluten-free? Use gluten-free pasta and breadcrumbs.
This dish reheats beautifully—cover with foil and bake at 350°F for 15-20 minutes until bubbly. Store leftovers in an airtight container for up to 5 days, or freeze for 3 months. For make-ahead prep, assemble the casserole (unbaked) up to a day ahead—just bake straight from the fridge, adding 10 minutes to the cooking time. The breadcrumb topping can be prepped ahead and stored in the fridge for 3 days, so you’re not scrambling last-minute. Pro tip: Spritz the baked mac and cheese with a little water before serving—it makes the breadcrumbs extra crispy.

Step-by-step instructions for baked mac and cheese with mustard powder
This method delivers a perfectly balanced baked mac and cheese with a subtle mustard kick that elevates every bite.
Cook the Elbow Macaroni to Al Dente Perfection
Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Season generously with 1.5 tsp salt—the water should taste like the sea. Cook until 1 minute before the package directions specify for al dente (usually about 10-11 minutes). This ensures the pasta finishes cooking in the oven without becoming mushy.
Drain the pasta in a colander and immediately rinse under cold water for 10 seconds to stop the cooking process. Shake off any excess water and return the pasta to the pot. Here's the thing—this quick rinse prevents a gummy texture while keeping the pasta from sticking together. Don't skip this step, or your mac and cheese will turn out gluey instead of creamy.
Create the Ultra-Smooth Cheese Sauce
In a large, heavy-bottomed skillet, melt 4 tbsp unsalted butter over medium heat. Once melted, whisk in 2 tbsp all-purpose flour and cook for 1-2 minutes until the mixture forms a light roux and smells nutty. This is your sauce foundation—don't rush this step or the sauce will taste raw.
Gradually whisk in 1 cup heavy cream and 1 cup whole milk, ensuring no lumps form. Stir constantly for 3-4 minutes until the mixture thickens slightly. Remove from heat and add 2 cups sharp white cheddar cheese, 1 cup gruyère cheese, 8 oz cream cheese, 1 tbsp mustard powder, 0.5 tsp garlic powder, 0.5 tsp black pepper, and the cooked macaroni. Mix until the cheese is completely melted and the sauce is smooth—this should take about 5 minutes of gentle stirring.
Combine and Transfer to Baking Dish
Transfer the cheese mixture to a 9x9-inch baking dish, spreading it evenly with a spatula. The dish should be about ¾ full—this gives the mac and cheese room to puff up slightly in the oven. Here's where the mustard powder works its magic: it adds just enough tang to cut through the richness of the cheeses, creating a perfectly balanced flavor profile.
Sprinkle the top with 0.5 cup panko breadcrumbs and 0.25 cup freshly grated parmesan cheese, pressing down gently to ensure they stick. This crispy topping adds texture contrast and prevents the cheese from getting too soft during baking. Preheat your oven to 375°F while you prepare the dish—this ensures even baking from the start.
Bake Until Golden and Bubbly
Place the baking dish in the center rack of your preheated oven and bake for 20-25 minutes. You'll know it's ready when the top is deep golden brown and the edges are bubbling vigorously. The mustard powder will have mellowed into the cheese, adding depth without overpowering the classic flavors.
For the best results, avoid opening the oven door during baking—each time you do, you lose heat and steam, which can lead to a less crispy top. If you're worried about over-browning, tent the dish with aluminum foil after 15 minutes and continue baking until the center is fully heated through.
Rest and Serve for Maximum Creaminess
Remove the mac and cheese from the oven and let it rest for 5-10 minutes before serving. This resting period allows the sauce to thicken slightly and the flavors to meld together. The internal temperature should reach 165°F—use an instant-read thermometer to check if you're unsure.
Serve immediately with a side of steamed broccoli or a simple green salad. Each bite should deliver creamy, melty cheese with a subtle mustard kick that brightens the rich flavors. The crispy panko topping adds a satisfying textural contrast that makes this baked mac and cheese truly exceptional.
Pro Tips For Making Baked Mac And Cheese Recipe With Mustard Powder
- Pre-cook the pasta: Toss the elbow macaroni in a pinch of salted pasta water before draining—it’ll absorb the cheese sauce better later. I used to skip this, and the sauce would always slide off the noodles like it was scared of them.
- Grate the cheeses unevenly: Mix sharp white cheddar and Gruyère with chunks left in—it melts faster and adds texture. I learned this the hard way after making a batch so smooth it tasted like a sad fondue.
- Temper the cream cheese: Warm the cream cheese with a splash of milk or broth first, then mix it into the sauce. Cold lumps are the fastest way to turn your creamy dream into a greasy mess.
- Bake uncovered for 5 minutes: Let the mac and cheese crisp on top under the broiler for the last 5 minutes—no foil needed. I was skeptical until I tried it; now I won’t serve it any other way.
Storing and reheating this dish
Refrigerator Storage
Store your baked mac and cheese in an airtight container for up to 5 days in the fridge. The mustard powder helps preserve freshness by preventing the cheese from turning rubbery.
I like using glass Pyrex containers—they keep flavors intact better than plastic. Always let it cool completely before covering to avoid condensation, which can make the breadcrumbs soggy. 🥫
Freezer-Friendly Tips
Freeze baked mac and cheese for up to 3 months by wrapping it tightly in plastic wrap first, then placing it in a freezer bag with all air removed. The mustard powder actually enhances the freezer experience by preventing the cheese from developing a "freezer burn" taste.
Thaw overnight in the fridge for best texture—microwaving straight from frozen can make it gummy. ❄️
Oven Reheating Method
Preheat your oven to 350°F and cover the mac and cheese with aluminum foil to trap moisture. Bake for 15-20 minutes until bubbly and heated through. The mustard powder adds a nice depth of flavor when reheated, making it taste almost as good as fresh.
If the breadcrumbs lose crispiness, sprinkle fresh panko on top and broil for 1-2 minutes at the end. 🔥
Microwave Hack
For quick reheating, cover the mac and cheese with a damp paper towel and microwave on 50% power for 2-3 minutes, stirring once halfway. The mustard powder helps maintain the sauce's creaminess even after reheating.
If it looks dry, add 1-2 tablespoons of milk and stir well. This method works best for single servings—just be careful not to overheat! ⚡
Make-Ahead Baking
Assemble your mac and cheese dish a day ahead—just skip the baking step. Cover tightly and refrigerate. When ready to bake, preheat the oven to 375°F and add 5-10 minutes to the baking time (it'll need the extra time coming from cold).
The mustard powder's tang becomes even more pronounced after resting, giving your dish extra depth. This is my go-to for busy weeknights! 📅
Crispy Top Revival
If reheated mac and cheese loses its crispy topping, sprinkle fresh panko breadcrumbs mixed with a little butter on top and broil for 2-3 minutes until golden. The mustard powder in the sauce will complement the fresh breadcrumbs beautifully.
For extra flavor, add a pinch of garlic powder or paprika to the breadcrumb mix. 🌟

Frequently asked questions
Why does this recipe use mustard powder instead of Dijon mustard?
The powdered form dissolves completely into the sauce, creating a subtle tang without any grainy texture. Dijon mustard can sometimes leave small specks, while mustard powder blends seamlessly for a smoother finish. Plus, it's shelf-stable and easier to measure precisely.
Can I make this recipe without cream cheese?
Yes, but the texture will be less creamy. Replace the 8 oz cream cheese with an extra ½ cup Gruyère and ¼ cup heavy cream for richness. The mustard powder will still work to balance flavors, though the sauce may be slightly firmer. For a vegan version, use cashew cream instead.
How do I prevent the top from getting soggy?
Press the breadcrumb topping firmly into the cheese before baking, and avoid opening the oven door during the first 15 minutes. For extra insurance, sprinkle an additional ¼ cup panko on top right after removing from the oven and broil for 1-2 minutes. The mustard powder in the sauce helps maintain crispiness by balancing moisture.
What's the best way to add protein to this dish?
Cooked bacon, crispy sausage crumbles, or shredded rotisserie chicken work beautifully. Fold them into the cheese sauce before baking, or sprinkle on top for extra texture. For a vegetarian option, try crispy chickpeas or sautéed mushrooms—the mustard powder's tang complements all these additions perfectly.
Can I use this recipe for a gluten-free version?
Swap regular pasta for gluten-free elbow macaroni and use gluten-free panko breadcrumbs. The mustard powder still enhances flavor without requiring gluten. Just ensure all other ingredients (like cheese) are certified gluten-free. The baking time may need an extra 5 minutes since gluten-free pasta absorbs sauce differently.
