Ingredients for baked mac and cheese recipe with dry mustard
Twelve ingredients, one game-changing flavor: dry mustard transforms classic mac and cheese into something extraordinary.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 12 oz | Dry, medium or short elbow |
| Sharp Cheddar Cheese 🧀 | 3 cups | Shredded, aged 2+ years |
| Gruyère Cheese 🧀 | 1 ½ cups | Shredded, French-style |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for sauce |
| All-Purpose Flour 🌾 | ¼ cup | For roux thickening |
| Whole Milk 🥛 | 1 ½ cups | Full-fat for creaminess |
| Dry Mustard Powder 🌶️ | 1 tsp | Key for nutty tang |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Panko Breadcrumbs 🍞 | ¼ cup | For crispy topping |
| Freshly Grated Parmesan 🧀 | ¼ cup | For final garnish |
| Smoked Paprika 🌶️ | ½ tsp | Optional for depth |
The cheeses are where the magic happens. Gruyère adds nutty depth while sharp cheddar delivers that classic tang—don't skimp on quality here. Whole Foods or Wegmans carry excellent pre-shredded options, but block cheese grated fresh melts better. The dry mustard is non-negotiable: Penzeys or McCormick brands work perfectly. For the pasta, elbow macaroni holds its shape best during baking, and Barilla is my go-to brand for consistent texture. If you're feeling adventurous, try cavatappi for extra pockets to hold cheese sauce.
No Gruyère? Parmigiano-Reggiano adds a similar sharpness, though the texture will differ slightly. Pre-shredded cheese? Toss it with 1 tsp cornstarch to prevent clumping. The dry mustard can be swapped for white miso paste (1/2 tsp)—it adds umami depth instead of tang. For a dairy-free version, use nutritional yeast (2 tbsp) plus 1/2 cup cashew cream. The smoked paprika is optional but worth it—Trader Joe's has a great affordable jar that lasts months. If your breadcrumbs get soggy during baking, toast them first**—just 2 minutes in a dry pan until golden.
This bakes best when made fresh, but components can be prepped ahead. Cook the pasta and refrigerate the cheese sauce separately for up to 2 days—reheat gently before baking. For make-ahead baking, assemble the casserole, refrigerate overnight, then bake straight from cold (add 10-15 minutes). Leftovers keep 4-5 days in the fridge, though they're rarely around that long. Freeze portions for up to 3 months—reheat covered with foil to prevent drying. The crispy top? Broil 2 minutes at the end for maximum crunch.

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 crispy breadcrumb topping.
🍳 Step 1: Cook the Elbow Macaroni to Perfect Al Dente
Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Cook until 1 minute before the package instructions for al dente—this ensures it finishes cooking in the oven without becoming mushy. I use a timer for precision, as overcooking leads to gummy pasta.
Before draining, reserve 1 cup of pasta water. This starchy liquid is essential for creating a silky sauce later. Drain the pasta and return it to the pot, shaking gently to break up any clumps. The pasta should be hot when you mix it with the cheese sauce.
🍳 Step 2: Make the Creamy Mustard Sauce
In a separate saucepan, melt 0.75 cup unsalted butter over medium heat until foaming. Whisk in 0.25 cup all-purpose flour and cook for 2 minutes until the mixture turns a pale golden color—this is your roux. Remove from heat immediately to prevent burning.
Gradually whisk in 1.5 cups whole milk, returning the pan to low heat. Stir constantly until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in 3 cups sharp cheddar cheese, 1.5 cups gruyère cheese, 1 tsp dry mustard powder, 1.5 tsp kosher salt, and 0.5 tsp ground black pepper. The mustard powder adds that signature nutty tang that sets this recipe apart.
🥘 Step 3: Combine Pasta and Sauce
Pour the hot cheese sauce over the hot pasta in the pot. Stir vigorously with a wooden spoon or rubber spatula until every strand is fully coated and creamy. The residual heat from the pasta helps melt the cheese completely, creating a smooth, velvety texture. If the sauce is too thick, add 1-2 tablespoons of reserved pasta water to loosen it.
Transfer the macaroni mixture to a 9x9-inch baking dish (or similar size). The dish should be lightly greased with butter or oil to prevent sticking. Spread the mixture evenly, pressing down gently with a spatula to create a smooth, even surface. This ensures even baking and a consistent texture throughout.
🔥 Step 4: Add Topping and Bake to Golden Perfection
In a small bowl, combine 0.25 cup panko breadcrumbs, 0.25 cup freshly grated parmesan, and 0.5 tsp smoked paprika. Sprinkle this mixture evenly over the top of the macaroni, pressing down lightly so it adheres. The panko will create a crispy, crunchy topping that contrasts beautifully with the creamy filling.
Bake at 375°F for 20-25 minutes until the top is golden brown and the edges are bubbling. The cheese should be fully melted, and the breadcrumb topping should be crispy. If the top browns too quickly, tent loosely with foil for the last 5 minutes to prevent burning while still allowing the cheese to melt.
⏰ Step 5: Rest and Serve Warm
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 internal temperature should reach 160°F—this ensures the cheese is fully melted and safe to eat.
Serve immediately with a side salad or steamed vegetables. The combination of sharp cheddar, nutty gruyère, and that mustard kick creates a depth of flavor that makes this mac and cheese stand out. Each bite delivers creamy, cheesy goodness with a satisfying crunch from the breadcrumb topping.
Pro Tips For Making Baked Mac And Cheese Recipe With Dry Mustard
- Cook pasta until firm: Mac and cheese needs to hold its shape under that heavy cheese sauce—don’t overcook the elbows to mushy. Test at 1 minute before package time, then drain immediately and shock in ice water for 30 seconds. (Yes, it’s annoying, but your future self will notice the difference.)
- Grate cheese aggressively: Sharp cheddar and Gruyère melt differently, so shred them separately and finely—almost like breadcrumbs. The finer the pieces, the smoother the sauce, and the less chance of grainy texture. (I used to skip this and wondered why my mac always looked like it had rocks in it.)
- Temper the roux: Cook the butter-flour mix low and slow until it’s pale golden—about 5 minutes—before adding milk. If it browns, the mustard will taste bitter. Keep the heat at a simmer, not a boil, or you’ll scramble the flour instead of thickening it properly.
- Mix mustard last: Stir in the dry mustard with the cheese, not the roux. Adding it too early can make the sauce curdle, and you’ll end up with a weird, grainy texture. A teaspoon or two is enough—more just makes it taste like a condiment. (I learned this after one very questionable batch.)
Make-ahead tips for this recipe
Prep Ahead Strategy
Cook the pasta and make the cheese sauce separately up to 2 days in advance. Store the cooked macaroni in an airtight container at room temperature, and refrigerate the cheese sauce in a separate container.
When ready to bake, reheat both components gently over low heat until fully melted and creamy. This method preserves texture and prevents a gummy final product. 🍝
Overnight Assembly
Assemble the casserole completely in your baking dish, then refrigerate overnight. When baking, add 10-15 extra minutes to the cook time since it starts cold. This technique actually enhances flavor development as the spices meld during the longer baking process.
The crispy breadcrumb topping will still form beautifully, just with a slightly longer bake. ❄️
Freezer-Friendly Method
For longer storage, assemble the casserole and freeze it in a single layer before baking. Use a 9x9-inch baking dish that fits in your freezer. When ready to bake, thaw overnight in the refrigerator, then bake as directed.
The texture remains creamy, though the breadcrumb topping may need 2-3 extra minutes to crisp up after thawing. 🧊
Reheating Leftovers
Leftovers can be reheated in the oven for the best results. Cover with foil and bake at 350°F for 15-20 minutes until heated through. For a quick microwave option, cover with a damp paper towel and heat in 1-minute intervals on 50% power, stirring between each interval.
Avoid overcooking to prevent a rubbery texture. 🔥
Portion Control
Divide baked mac and cheese into individual quart-sized freezer bags for easy portioning. Flatten the bags to save space and label with the date. When reheating frozen portions, bake at 375°F for 25-30 minutes covered with foil, then uncover for the final 2-3 minutes to crisp the top.
This method maintains the perfect balance of creamy and crispy. 🍽️
Make-Ahead Topping
Prepare the breadcrumb topping separately and store it in a small airtight container. Toast the panko and parmesan mixture ahead of time for extra flavor, then sprinkle it on just before baking.
This keeps the topping crispy and prevents it from absorbing moisture during storage. The dry mustard flavor remains vibrant when stored this way. 🧂

Frequently asked questions
Why does dry mustard make such a difference in baked mac and cheese?
The 1 teaspoon of dry mustard powder adds a subtle, nutty tang that enhances the cheese flavor without overpowering it. It creates depth that transforms basic mac and cheese into something sophisticated—think of it as the secret ingredient that makes the dish taste restaurant-quality. The mustard also helps balance the richness of the cheddar and Gruyère.
Can I substitute dry mustard with another ingredient?
Yes! For a similar tang, try 1/2 teaspoon of white miso paste or 1/4 teaspoon of Dijon mustard (mixed into the sauce). If you prefer a sharper flavor, add 1/4 teaspoon of smoked paprika or a pinch of cayenne. The mustard is optional, but omitting it will make the dish taste more traditional.
How do I fix a watery mac and cheese after baking?
If your baked mac and cheese is too runny, the issue is often undercooked roux or too much milk. For immediate fixes, sprinkle 1 tablespoon of cornstarch mixed with 1 tablespoon cold water over the top and bake for 5-10 minutes more. For next time, ensure your roux cooks to a golden color and use 1.5 cups milk (not more).
What’s the best way to make this vegan?
Replace the butter with vegan butter or olive oil, use unsweetened almond milk instead of whole milk, and swap cheeses for vegan cheddar and nutritional yeast. For the mustard kick, add 1/2 teaspoon white miso paste. The texture will be creamier but still delicious—just ensure your vegan cheese melts well.
Can I broil this for a crispier top?
For a golden, crispy crust, broil for 2-3 minutes at the end of baking. Watch closely to avoid burning—remove from the oven as soon as the top turns golden brown. The broiler adds extra crunch while keeping the inside creamy. Just make sure your breadcrumb topping is fully set before broiling.
