- 1 ½ teaspoons salt: Elevates all the flavors harmoniously.
- 1 teaspoon black pepper: Adds a gentle kick and depth of flavor.
- 1 teaspoon mustard powder: Enhances the cheese’s natural sharpness with a subtle tang.

How to Make Baked Mac and Cheese with Cheez-It Crust Recipe
Step 1: Prepare Your Pasta and Cheese
Start by preheating your oven to 350°F so it’s ready when your mac and cheese comes together. Bring a large pot of salted water to a boil, then add the macaroni noodles and cook them according to the package directions until al dente. Drain and set aside. While the pasta is cooking, shred your sharp cheddar and Swiss cheese. Having everything ready now will make the sauce preparation smooth and seamless.
Step 2: Make the Roux and Seasoned Cheese Sauce
In a large saucepan or Dutch oven over medium heat, melt ¼ cup of the unsalted butter. Once melted, whisk in the ¼ cup of flour to create a roux. This will be the thickening base for your sauce. Stir in the salt, black pepper, mustard powder, and the hot sauce dashes. Let this cook for 1 to 2 minutes—you’ll start to smell those spices blooming and that’s when the flavor foundation gets set.
Step 3: Add Cream and Melt the Cheese
Lower the heat to medium-low and slowly stream in the half and half, whisking continuously to combine it smoothly with your roux mixture. Bring it gently to a boil, then stir in 2 cups of the shredded cheddar cheese and all of the Swiss cheese. Keep stirring until all that cheese melts into a dreamily creamy sauce. This step is where the magic happens—the sauce becomes thick, gooey, and utterly irresistible.
Step 4: Combine Pasta and Cheese Sauce
Take the sauce off the heat and fold in the perfectly cooked macaroni noodles so every piece is coated with cheesy goodness. Then transfer this mixture into a greased 9-inch by 13-inch baking dish, spreading it out evenly. The dish is now ready for its crunchy topping to take it over the edge.
Step 5: Craft the Cheez-It Crust
Place the Cheez-It crackers in a large zipper bag and crush them with a rolling pin or pulse them in a food processor until they’re broken into fine, crumb-like pieces. In a medium bowl, melt the remaining ¼ cup of butter, then combine it with the crushed Cheez-It crackers and the reserved ¼ cup of shredded cheddar cheese. This mixture will be sprinkled generously over the mac and cheese, adding an addictive salty crunch.
Step 6: Bake to Perfection
Sprinkle the buttery Cheez-It crust evenly over the top of your mac and cheese, then place the baking dish into the oven. Bake for 30 minutes, allowing the cheese sauce to bubble and the crust to turn golden brown and crispy. If you love an extra crunch, switch the oven to broil on high for the last 2 minutes, but watch it closely to avoid burning. This final step creates the unforgettable crispy Cheez-It crust that makes this Baked Mac and Cheese with Cheez-It Crust Recipe so unique.
How to Serve Baked Mac and Cheese with Cheez-It Crust Recipe
Garnishes
To elevate this comforting dish even more, sprinkle some freshly chopped parsley or chives on top just before serving. The bright green herbs add a pop of color and a fresh contrast to the rich, cheesy flavors. You can also add a light dusting of smoked paprika or a few extra grinds of black pepper for a little visual flair and subtle spice.
Side Dishes
This mac and cheese shines beautifully as a main course, but it also pairs wonderfully with crisp, refreshing side dishes. Try serving it alongside a simple green salad tossed in a tangy vinaigrette or roasted vegetables like broccoli or Brussels sprouts, as their bitterness perfectly balances the creamy richness. For a heartier meal, crispy baked chicken tenders or grilled sausages complement the dish marvelously.
Creative Ways to Present
If you want to impress guests, consider serving the mac and cheese in individual ramekins or mini cast iron skillets topped with the Cheez-It crust. This adds a rustic and elegant touch. Another fun idea is to transform leftovers into stuffed bell peppers by filling them with reheated mac and cheese and topping with additional crushed Cheez-Its before baking until bubbly and golden.
Make Ahead and Storage
Storing Leftovers
You can store leftover Baked Mac and Cheese with Cheez-It Crust Recipe in an airtight container in the refrigerator for 3 to 4 days. To keep the crust crunchy, try storing it separately from the mac and cheese base, then adding the topping fresh before reheating.
Freezing
This dish freezes well! Prepare it fully but don’t bake it yet, then cover tightly with foil or plastic wrap and freeze for up to 2 months. When ready, bake from frozen at 350°F until heated through and the crust is crisp, adding the broil step at the end if desired.
Reheating
To bring leftovers back to life, reheat in a 350°F oven for about 20 minutes or until bubbly and warmed through. If the topping has softened, briefly broil for 1-2 minutes to restore that crispy Cheez-It crust. Avoid the microwave when possible to keep the texture at its best.
FAQs
Can I use other cheeses instead of cheddar and Swiss?
Absolutely! While sharp cheddar and Swiss create a perfect balance, feel free to experiment with mozzarella, gouda, or even a smoky cheese for a different but delicious twist on the recipe.
Is there a vegetarian version of this recipe?
This recipe is naturally vegetarian as it contains no meat. Just make sure your hot sauce and cheese are vegetarian-friendly if that’s a concern.
How can I make this recipe spicier?
To amp up the heat, add more hot sauce or cayenne pepper to the roux, or sprinkle crushed red pepper flakes on top before baking for an extra kick alongside the Cheez-It crust.
Can I use different pasta shapes?
Yes! While elbow macaroni is classic, other small pasta shapes like shells, cavatappi, or penne work equally well as they all hold the cheese sauce beautifully.
What is the best way to crush Cheez-It crackers?
For the easiest and most even crumb size, using a food processor is ideal. If you don’t have one, placing the crackers in a sealed bag and rolling over them with a rolling pin or the bottom of a heavy pan works great too.

Ingredients
Pasta and Cheese Sauce
- 16 ounces uncooked macaroni noodles
- 8 ounces sharp cheddar cheese, shredded (about 2 ¼ cups)
- 8 ounces swiss cheese, shredded (about 2 ¼ cups)
- ½ cup unsalted butter, divided
- ¼ cup all-purpose flour (or 2 tablespoons cornstarch)
- 1 ½ teaspoons salt
- 1 teaspoon black pepper
- 1 teaspoon mustard powder
- 3–4 dashes hot sauce (or ¼ teaspoon cayenne pepper)
- 3 cups half and half (or whole milk)
Crust
- 2 cups Cheez-It crackers
- ¼ cup unsalted butter (melted)
- ¼ cup shredded sharp cheddar cheese (reserved from above)
Instructions
- Preheat the oven. Set your oven to 350°F (175°C) to get it ready for baking the mac and cheese.
- Cook the macaroni. Bring a large pot of salted water to a boil on the stove, then add the macaroni noodles. Cook according to the package directions until tender but still firm to the bite. Drain the noodles and set them aside.
- Prepare the cheese. While the pasta cooks, shred the sharp cheddar and Swiss cheeses and set them aside separately, reserving part of the cheddar for the topping.
- Make the roux and sauce. Heat a large saucepan or Dutch oven over medium heat. Add ¼ cup of the unsalted butter and let it melt. Whisk in the flour to form a roux, cooking for 1 to 2 minutes while adding salt, black pepper, mustard powder, and hot sauce or cayenne pepper. Slowly add the half and half while whisking continuously to avoid lumps, and bring the mixture to a gentle boil to thicken.
- Incorporate the cheeses. Lower the heat to medium-low and stir in 2 cups of shredded cheddar and all of the Swiss cheese. Keep stirring until the cheeses melt completely and the sauce is smooth and creamy.
- Combine pasta and cheese sauce. Remove the cheese sauce from heat and mix in the drained macaroni noodles until they are fully coated with the creamy sauce.
- Prepare the baking dish. Transfer the cheesy macaroni mixture to a greased 9×13 inch baking dish, spreading it out evenly.
- Make the Cheez-It crust. Crush the Cheez-It crackers by placing them into a large zipper bag and rolling with a rolling pin, or pulse them a few times in a food processor to achieve coarse crumbs.
- Mix the topping. In a medium bowl, melt the remaining ¼ cup of unsalted butter. Combine this melted butter with the crushed Cheez-Its and the reserved ¼ cup shredded cheddar cheese, mixing well.
- Top and bake. Evenly sprinkle the Cheez-It crust mixture over the mac and cheese in the baking dish. Place in the preheated oven and bake for 30 minutes until bubbly and golden on top.
- Optional broil for extra crispiness. If you prefer an extra crispy topping, switch the oven to broil on high for the last 2 minutes of baking—watch carefully to prevent burning.
Notes
- For a lactose-free version, substitute half and half with lactose-free milk and use lactose-free cheese.
- You can substitute Cheez-It crackers with any crunchy cheese crackers if desired.
- For a spicier kick, increase the hot sauce or cayenne pepper slightly, but add carefully to taste.
- Make sure to watch closely during broiling to avoid burning the topping.
- Leftovers keep well refrigerated for up to 3 days and reheat nicely in the oven or microwave.
