Ingredients for baked mac and cheese recipe mustard
These cheesy, mustard-kissed ingredients create the ultimate baked mac and cheese magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 12 oz | Uncooked, dry pasta |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for roux |
| All-Purpose Flour 🌾 | ½ cup | For perfect roux texture |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, aged for tang |
| Gruyère Cheese 🧀 | 1 cup | Shredded, nutty flavor |
| Cream Cheese 🧀 | 8 oz | Softened for creaminess |
| Dijon Mustard 🌶️ | 1 ½ tbsp | Sharp, high-quality mustard |
| Whole Milk 🥛 | 1 ½ cups | Warmed for smooth sauce |
| Garlic Cloves 🧄 | 2 cloves | Minced for subtle depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Panko Breadcrumbs 🍞 | ¼ cup | For crispy topping |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For breadcrumb richness |
The cheese blend makes this dish extraordinary. Sharp cheddar delivers that classic tang, while Gruyère adds nutty depth—don't substitute with mild cheddar. For the best texture, shred your own cheese (pre-shredded gets clumpy). Trader Joe's has excellent pre-shredded options if you're short on time, but I always grab blocks to grate fresh. The Dijon mustard? Maille or Colman's are my go-tos—they've got that perfect balance of sharpness without overpowering. And that cream cheese? Full-fat, please—it's what gives this dish that luxurious creaminess we all crave.
No Dijon mustard? Yellow mustard at half the amount works in a pinch, but you'll lose some complexity. Running low on Gruyère? Parmesan adds saltiness while Pepper Jack brings heat. The breadcrumbs can be regular, but panko gives that perfect crispy texture—worth the extra dollar. For the roux, don't rush it—cook that butter and flour until it's golden brown for that nutty flavor that makes everything better. And if you're worried about the mustard being too strong, remember it'll mellow out as it bakes. Trust me on this one.
This mac and cheese tastes even better the next day—honestly, it's the best part. Keeps 4-5 days in the fridge, covered, but I usually eat it all by day two. For leftovers, reheat covered in the oven at 350°F until bubbly. The breadcrumb topping gets extra crispy when reheated—perfect for soaking up any extra sauce. Freezes beautifully for 3 months if you want to make ahead. Just thaw overnight in the fridge before reheating.

Step-by-step instructions for baked mac and cheese with mustard
Here's how to make that perfect pull-apart mac and cheese with sharp mustard heat and gooey perfection.
🍳 Step 1: Cook the Macaroni to Al Dente
Bring a large pot of water to a rolling boil and add 1 teaspoon salt—it should taste like the ocean. Add the 12 oz elbow macaroni and cook until 1 minute before the package instructions say al dente. You want it to finish cooking in the oven so it doesn't get mushy.
I like to test the pasta by tasting a piece—it should be firm but still slightly resistant. Drain it in a colander, but don't rinse it. That surface starch is what helps the cheese sauce cling perfectly to every noodle. Give it a quick shake to break up any clumps, then transfer to a large bowl.
👨🍳 Step 2: Make the Ultimate Mustard-Cheese Sauce
In a separate large skillet, melt the ½ cup unsalted butter over medium heat until it's completely melted and foaming. Whisk in the ½ cup all-purpose flour and cook for 2-3 minutes until it forms a smooth, pale roux—this is your sauce foundation. Don't let it brown or it'll get bitter.
Slowly whisk in the 1½ cups warm whole milk (warmed in the microwave for 30 seconds) and continue whisking until the mixture thickens to a creamy consistency. Reduce heat to low and stir in the 1½ tbsp Dijon mustard, 2 cups sharp cheddar cheese, 1 cup Gruyère cheese, 8 oz cream cheese, 2 minced garlic cloves, ½ tsp black pepper, and remaining ½ tsp salt.
Let the mixture cook for 3-4 minutes until it's completely melted and smooth. Here's the thing—this is where the magic happens. The mustard adds that sharp, tangy kick that cuts through the richness of all that cheese. Taste and adjust seasoning if needed—you want that perfect balance of sharp, salty, and creamy.
🥘 Step 3: Combine and Bake to Golden Perfection
Pour the cheese sauce over the cooked macaroni and stir until every noodle is completely coated and glistening. The mixture should look thick and luxurious—almost like a creamy pasta. Transfer everything to a greased 9x13-inch baking dish and spread it out evenly.
Preheat your oven to 375°F. Here's where the fun part comes in—sprinkle the ¼ cup panko breadcrumbs mixed with 1 tbsp extra-virgin olive oil evenly over the top. The breadcrumbs will create that perfect crispy crust while keeping the inside gooey. Bake uncovered for 20-25 minutes until the top is golden brown and the edges are bubbling.
🔥 Step 4: Broil for Extra Crispiness (Optional but Worth It!)
For that restaurant-quality finish, switch your oven to broil and place the dish on the top rack. Watch it like a hawk—you want the top to get deep golden brown with some spots of toasted breadcrumbs, but not burnt. This usually takes 2-3 minutes. If you're unsure, check it at 2 minutes and adjust accordingly.
Let the mac and cheese rest for 5-10 minutes before serving. This resting time is crucial—it lets the cheese set slightly so it holds together better when you cut into it. The result should be a perfect pull-apart texture with that crispy, mustard-kissed top and creamy, cheesy goodness underneath.
Pro Tips For Making Baked Mac And Cheese Recipe Mustard
- Cook Pasta Al Dente: Mac and cheese starts with the pasta—don’t overcook it. Pull elbows out when they’re still slightly firm (about 1 minute less than package instructions), then finish cooking in the cheese sauce. I learned this the hard way: mushy pasta ruins everything, even with the best sauce.
- Melt Cheese Slowly: Low and slow is the name of the game. Heat your cheese sauce on medium-low, stirring constantly, or you’ll end up with scrambled cheese instead of a smooth, velvety texture. Gruyère especially burns if you rush it—trust the process.
- Skip the Pre-Shredded Cheese: Pre-shredded cheese has anti-caking agents that make the sauce grainy. Grate your own sharp cheddar and Gruyère—it’s worth the extra 5 minutes. The texture difference is night and day.
- Broil for Crust, Not Burn: When broiling, watch it like a hawk. High heat = fast crust, but it can turn into a sad, rubbery mess. Start with 2-3 minutes, then check—you want golden, not blackened. A quick broil is better than a disaster.
Storing and reheating this recipe
Fridge Storage Secrets
Let your mac and cheese cool completely before transferring to an airtight container—I swear by glass Pyrex with snap-on lids for best results. Store at 40°F or below for up to 4-5 days, though honestly? It disappears faster than that.
The mustard flavor actually deepens overnight, making leftovers even more delicious. Just be sure to press plastic wrap directly on the surface before sealing to prevent that dreaded cheese crust from forming. 💛
Freezer-Friendly Tips
This mac and cheese freezes beautifully for up to 3 months—perfect for lazy weeknights. I recommend quart-sized freezer bags with 1 inch headspace for expansion. Squeeze out all the air and label with the date.
When ready to eat, thaw overnight in the fridge for even reheating. Pro tip: Add a splash of milk when reheating to restore that creamy texture if it looks dry.
Oven Reheating Perfection
For the best texture, cover your mac and cheese with foil and reheat at 350°F until bubbly—usually 15-20 minutes. The broiler finish from earlier? It comes back to life beautifully, giving you that crispy top again.
If you're short on time, the microwave works too: 50% power for 2 minutes, stir, then continue in 30-second bursts until heated through. Just add a splash of milk if it starts looking dry.
Crispy Top Revival
Lost that perfect golden crust? No problem! Sprinkle a little extra panko mixed with butter on top before reheating, then broil for 1-2 minutes until crispy. This works wonders for both oven and microwave reheats.
For extra flavor, add a pinch of smoked paprika or garlic powder to the panko before topping. Trust me, it makes all the difference when you're craving that restaurant-quality texture. ✨
Make-Ahead Magic
Prep this dish completely one day ahead—it's my go-to for busy days. Assemble everything in the baking dish, cover tightly with foil, and refrigerate. Bake straight from the fridge at 375°F for 30-35 minutes (the extra time accounts for the cold start).
The mustard flavor really shines when made ahead, giving you that perfect balance of sharp and creamy every time. Just

Frequently asked questions
Can I use yellow mustard instead of Dijon in this recipe?
You can substitute yellow mustard, but use only 1 tablespoon (half the amount) since it's milder. The Dijon's sharpness enhances the cheese flavors, but yellow mustard will still add a subtle tang. For best results, stick with Dijon if possible—it creates that perfect balance of heat and creaminess.
Why does my baked mac and cheese get watery after baking?
This usually happens when the pasta is overcooked or too much liquid is added. Always cook pasta 1 minute less than package instructions and drain well. If your sauce looks too thin, let it simmer uncovered for 2-3 extra minutes to thicken. The mustard helps balance moisture, but too much liquid can still dilute the cheese.
Can I make this recipe ahead of time?
Assemble the dish completely, cover tightly with foil, and refrigerate for up to 24 hours. Bake straight from the fridge at 375°F for 30-35 minutes. The mustard flavor actually deepens when made ahead, creating even more complex taste. Just add 5 extra minutes to account for the cold start.
What's the best way to reheat leftovers?
For perfect texture, cover with foil and reheat at 350°F for 15-20 minutes until bubbly. For quick reheating, use 50% microwave power for 2 minutes, stir, then continue in 30-second bursts. Add a splash of milk if it looks dry. The crispy topping can be revived by sprinkling extra panko and broiling for 1-2 minutes.
Can I add other vegetables to this recipe?
Yes! Try adding ½ cup diced broccoli or roasted butternut squash to the pasta before baking. For best texture, blanch vegetables first and drain well. The mustard's sharpness pairs beautifully with earthy veggies. Just reduce the cheese by ¼ cup to maintain the perfect balance of flavors.
