How to Make Baked Mac and Cheese with Cheez-It Crust Recipe
Step 1: Cook the Macaroni
Start by bringing a large pot of salted water to a boil, then add the macaroni noodles. Follow the package directions to cook them just right—al dente is perfect for this recipe so they don’t become mushy after baking. Once cooked, drain the noodles and set them aside to prep the cheese sauce.
Step 2: Prepare the Cheese Sauce
While the pasta is cooking, shred your sharp cheddar and Swiss cheese. In a large saucepan or Dutch oven, melt ¼ cup of unsalted butter over medium heat. Once melted, whisk in ¼ cup of flour to create a roux, cooking gently for 1-2 minutes to remove the raw flour taste.
Step 3: Season and Add the Milk
To the roux, add 1 ½ teaspoons salt, 1 teaspoon black pepper, 1 teaspoon mustard powder, and 3 to 4 dashes of hot sauce. Whisk everything together to blend well and develop flavor. Lower the heat to medium-low and slowly pour in the half and half, whisking constantly to avoid lumps. Bring this mixture to a gentle boil so it thickens into a velvety base.
Step 4: Melt in the Cheese
Stir in 2 cups of shredded cheddar (saving ¼ cup for the topping) along with all the Swiss cheese. Continue stirring to melt the cheeses into a smooth, creamy sauce that clings to every noodle beautifully.
Step 5: Combine Pasta and Sauce
Remove the saucepan from the heat and fold the cooked macaroni noodles into the luscious cheese sauce until every piece is coated. Then transfer everything to a greased 9×13-inch baking dish, spreading it out evenly.
Step 6: Make the Cheez-It Crust
Place the Cheez-It crackers in a large zipper bag and crush them with a rolling pin, or pulse briefly in a food processor until coarse crumbs form. In a medium bowl, melt the remaining ¼ cup of butter and combine it with the crushed crackers along with the reserved cheddar cheese.
Step 7: Top and Bake
Sprinkle the buttery Cheez-It crust mixture evenly over the mac and cheese in your baking dish. Place it in the oven preheated to 350°F and bake for 30 minutes until bubbly and golden brown on top. For an extra crispy finish, switch the oven to broil on high for the last 2 minutes, watching carefully to avoid burning.
How to Serve Baked Mac and Cheese with Cheez-It Crust Recipe

Garnishes
To finish off your Baked Mac and Cheese with Cheez-It Crust Recipe with flair, sprinkle some freshly chopped parsley or green onions over the top. These garnishes add a pop of freshness and color that contrast beautifully with the warm, rich cheese.
Side Dishes
This dish is hearty enough to stand alone but pairs wonderfully with crisp green salads or steamed vegetables like broccoli or green beans, which add a nutritious crunch and balance out all that indulgent cheese.
Creative Ways to Present
For a fun twist, serve the mac and cheese in individual ramekins topped with mini Cheez-It crusts, perfect for gatherings or dinner parties. You can also try mixing in cooked bacon or caramelized onions before baking for extra smoky or sweet flavor accents.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover Baked Mac and Cheese with Cheez-It Crust Recipe tightly with foil or plastic wrap and keep it in the refrigerator. It will stay fresh for up to 3-4 days, making it a convenient and comforting meal later in the week.
Freezing
This dish freezes well! Portion it out into freezer-safe containers before baking for easy grab-and-bake meals. Or freeze the fully baked dish tightly wrapped for up to 2 months. Thaw in the refrigerator before reheating for best texture.
Reheating
Reheat leftovers in the oven at 350°F covered with foil to prevent drying out, removing the foil towards the end to crisp the topping. You can also microwave individual servings, but the crust may lose its crunch so oven reheating is preferred.
FAQs
Can I use different types of cheese for this recipe?
Absolutely! While sharp cheddar and Swiss offer a classic combo, feel free to experiment with cheeses like Gruyère, mozzarella, or Monterey Jack to tailor the flavor to your liking.
What if I don’t have Cheez-It crackers?
You can substitute with other cheese crackers or even seasoned breadcrumbs for a tasty crust, though the unique sharpness of Cheez-Its really makes this recipe stand out.
Is it possible to make this gluten-free?
Yes! Use gluten-free pasta and a gluten-free flour or cornstarch for the roux. Just be sure your Cheez-It substitutes are gluten-free as well for a safe and delicious alternative.
Can I make this recipe vegan?
Traditional baked mac and cheese is tough to veganize exactly, but you can use plant-based cheeses, vegan butter, and milk substitutes to achieve a similar comfort food vibe with a creative twist.
How spicy is the hot sauce in this recipe?
The hot sauce adds just a gentle warmth that balances the richness of the cheese without overwhelming it. You can adjust the amount or omit it altogether if you prefer a milder dish.
