Ingredients for baked mac and cheese recipe with ground mustard
Twelve ingredients transform ordinary mac and cheese into a tangy, restaurant-worthy masterpiece—ground mustard is the game-changer!
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 12 oz | Dry, uncooked, medium or elbow shape |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | 1 cup | Shredded, aged for nutty flavor |
| Heavy Cream 🥛 | 1 cup | Full-fat for best creaminess |
| Whole Milk 🥛 | ½ cup | Warmed for smooth sauce |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for sauce |
| Ground Yellow Mustard 🌶️ | 1 tsp | Key for tangy sophistication |
| All-Purpose Flour 🌾 | ¼ cup | For roux, sifted |
| Garlic Cloves 🧄 | 2 cloves | Minced, for aromatic depth |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground for heat |
| Breadcrumbs 🍞 | ¼ cup | Panko for crispy topping |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For breadcrumb topping |
The cheeses are where the magic happens. Sharp white cheddar delivers that classic tang, while Gruyère adds nutty depth—both should be freshly shredded (pre-shredded gets clumpy). I grab mine from Whole Foods or Wegmans because their cheese counters have the best selection. The mustard? French's yellow is my go-to—it's consistent and affordable, but any good-quality ground mustard works. Pro tip: Toast your breadcrumbs in a dry pan for 2 minutes before adding oil—they'll be crispier. And always use full-fat cream and milk—low-fat versions make the sauce watery.
No Gruyère? Parmesan or sharp cheddar in its place works beautifully. Short on breadcrumbs? Crushed cornflakes or panko are great substitutes. The mustard is non-negotiable for that tangy kick, but if you're avoiding mustard entirely, a pinch of smoked paprika adds a similar depth. For the roux, don't rush it—cook the butter and flour until it's a rich golden color before adding liquids. That's where the flavor really develops. And if you're worried about the dish being too rich, add a splash of chicken or vegetable broth to the sauce to lighten it up.
This reheats like a dream—just cover with foil and bake at 350°F for 15-20 minutes until bubbly. Leftovers keep for 4-5 days in the fridge, but honestly, it's even better the next day once all the flavors meld. For meal prep, portion into individual baking dishes before freezing—3 months in the freezer, no problem. The breadcrumb topping stays crispy if you reheat it covered, then uncover for the last 2 minutes. Double the recipe? Easy—just scale everything up and use a larger baking dish.

Step-by-step instructions for baked mac and cheese with mustard
Here's how to transform simple ingredients into a rich, tangy mac and cheese with a golden crust.
🍳 Step 1: Cook the Elbow Macaroni to Perfect Al Dente
Bring a large pot of water to a rolling boil and add 1 tablespoon salt. Add the 12 oz elbow macaroni and cook until 1 minute before the package instructions say "al dente" - you want it just slightly firm. Drain immediately and return to the pot.
I like to give the pasta a quick rinse under cold water to stop the cooking process. Then I toss it with 1 tablespoon extra-virgin olive oil to prevent sticking. This step is crucial - overcooked pasta turns mushy in the oven, while slightly undercooked pasta finishes perfectly in the cheesy sauce.
👨🍳 Step 2: Build the Mustard-Infused Cheese Sauce
In a separate large skillet, melt ½ cup unsalted butter over medium heat until foaming. Add the 2 cloves minced garlic and cook for 30 seconds until fragrant - you'll smell that delicious garlic aroma. Immediately whisk in the ¼ cup all-purpose flour and cook for 1-2 minutes until it forms a smooth roux.
Slowly pour in the ½ cup warm whole milk and whisk constantly until the mixture thickens. Then add the 1 cup heavy cream, 1 teaspoon ground yellow mustard, ½ teaspoon salt, and ¼ teaspoon black pepper. Stir in 2 cups shredded sharp white cheddar cheese and 1 cup shredded gruyère cheese until completely melted and smooth.
🥘 Step 3: Combine Pasta and Sauce
Pour the cheese sauce over the cooked macaroni and stir vigorously with a wooden spoon for 2-3 minutes until every strand is coated. The sauce should be thick enough to cling to the pasta without being gluey. If it's too thick, add 1-2 tablespoons milk to loosen it.
This is where the magic happens - the mustard adds that sharp tang that cuts through the richness of the cheese. Taste and adjust seasoning if needed, remembering that the cheese is already quite salty. Transfer the mixture to a greased 9x13-inch baking dish and spread it evenly.
🔥 Step 4: Create the Crispy Breadcrumb Topping
In a small bowl, combine the ¼ cup breadcrumbs with 1 tablespoon extra-virgin olive oil and ¼ teaspoon black pepper. Sprinkle this mixture evenly over the top of the macaroni. The breadcrumbs should form a thin, even layer that will crisp up beautifully in the oven.
Here's the thing - don't skip this step! The breadcrumb topping gives you that perfect textural contrast between the creamy mac and cheese and the crispy top. It also prevents the cheese from getting too oily on top.
⏰ Step 5: Bake to Golden Perfection
Preheat your oven to 375°F. Bake the mac and cheese for 20-25 minutes until the top is golden brown and the edges are bubbling. If your oven runs hot, you might need to reduce the temperature to 350°F and bake for 25-30 minutes.
I know it's tempting to peek, but resist! Every time you open the oven, you lose heat and steam, which can make the top less crispy. When it's done, let it rest for 5-10 minutes before serving - this gives the layers time to set properly. The result should be creamy, cheesy, tangy perfection with a crispy top that's impossible to resist!
Pro Tips For Making Baked Mac And Cheese Recipe With Ground Mustard
- USE LOW AND SLOW FOR THE CHEESE SAUCE: I learned this the hard way—boiling the cheese sauce on high heat turns it grainy. Keep it at a gentle simmer, stirring constantly, until the cheddar and Gruyère melt completely. The mustard should just warm through, not cook aggressively.
- GRATE THE CHEESE FINE: Big cheese chunks? No thank you. Use a box grater for the cheddar and Gruyère—smaller pieces melt faster and blend smoother into the sauce. (Yes, even if you’re impatient like me.)
- DRAIN THE PASTA WELL: Soggy mac and cheese is a crime. Drain the elbow pasta and give it a good rinse under cold water, then shake it dry in the colander. The extra starch makes the sauce cling, but too much turns it gluey.
- TOAST THE MACARONI: Before mixing, spread the drained pasta on a baking sheet and toast it in a 375°F oven for 5 minutes. It crisps up slightly, adding texture that cuts through the richness of the mustard and cream. (Your future self will thank you.)
Perfect pairings for this recipe
Crispy Sides
Serve this mustard-kissed mac and cheese with garlic-parmesan roasted broccoli—toss 2 lbs broccoli florets with 2 tbsp olive oil, 1 tbsp minced garlic, ¼ cup grated parmesan, and ½ tsp salt.
Roast at 425°F for 15-18 minutes until crispy. The broccoli's peppery bite cuts through the richness beautifully. 🌱
For a heartier option, try crispy sage and onion fritters—sauté 1 diced onion and 4 chopped sage leaves until soft, mix with 1 cup flour, 1 egg, and ½ cup milk, then pan-fry in ¼ inch oil until golden.
The savory crunch balances the creamy mac perfectly.
Protein Pairings
A smoked turkey breast roast (seasoned with ½ tsp smoked paprika and ¼ tsp garlic powder) makes this dish feel like a full meal. Cook the 1.5 lb turkey breast at 325°F for 1.5-2 hours until internal temp hits 165°F.
The smoky notes complement the mustard's tang without overpowering it.
For a lighter option, grilled lemon-herb chicken works wonderfully. Marinate 4 boneless chicken breasts in 3 tbsp olive oil, 1 tbsp lemon juice, 1 tsp dried oregano, and ½ tsp salt for 30 minutes before grilling. The citrus brightens the dish and keeps it fresh.
Unexpected Toppings
Add a crispy fried egg on top right before serving—crack 4 eggs into a hot skillet with 1 tbsp butter, cover until whites set, then flip for a runny yolk. The egg's richness and warmth take this dish to new heights. 🍳
For a vegetarian twist, try toasted pumpkin seeds—toss ½ cup raw pumpkin seeds with 1 tsp olive oil and ¼ tsp salt, then toast in a dry pan for 3-4 minutes until golden. Their nutty crunch adds texture and a subtle earthiness that pairs beautifully with the mustard.
Beverage Pairings
A crisp Chardonnay with hints of lemon and apple (like La Crema Sonoma Coast) cuts through the richness while complementing the mustard's tang. The wine's acidity cleanses your palate between bites—perfect for a cozy dinner. 🍷
For beer lovers, a hoppy pale ale (such as Deschutes Mirror Pond) balances the dish's creaminess with its bitterness. The malt sweetness also enhances the Gruyère's nutty notes, creating a harmonious flavor profile.

Frequently asked questions
Can I use Dijon mustard instead of ground mustard?
Yes, but you'll need to adjust the amount. Use about 1 teaspoon Dijon mustard for every ½ teaspoon ground mustard in the recipe. Dijon has a stronger flavor, so start with less and taste as you go. The ground mustard in this recipe dissolves completely into the sauce, while Dijon might add visible texture if overused.
Why does my baked mac and cheese get watery?
This usually happens from overcooked pasta or too much liquid in the sauce. Cook your macaroni just until al dente (1 minute less than package instructions), and don't over-rinse it. If the sauce seems too thin, let it simmer uncovered for 2-3 minutes to reduce. For extra insurance, stir in 1 tablespoon cornstarch mixed with 1 tablespoon cold water at the end.
Can I make this ahead of time?
This mac and cheese actually tastes better the next day. Assemble it completely (including the breadcrumb topping) and refrigerate for up to 24 hours. When ready to bake, cover with foil and bake at 350°F for 30-40 minutes until heated through. For freezing, bake it first, then let cool completely before wrapping tightly in plastic wrap and foil.
What's the best way to reheat leftovers?
For the crispiest results, cover with foil and reheat at 350°F for 15-20 minutes until bubbly. Then uncover and broil for 1-2 minutes to restore the crispy breadcrumb topping. If using the microwave, cover with a damp paper towel and heat in 30-second intervals until hot, stirring between each interval to prevent drying out.
Can I make this vegetarian?
Yes, and it works beautifully! Just ensure all your cheeses are vegetarian-certified (some whey-based cheeses aren't). For extra richness, add 2 tablespoons nutritional yeast to the sauce - it adds a cheesy flavor and boosts protein. The mustard's tang still shines through while keeping the dish completely plant-based.
