If you love classic mac and cheese but crave more crispy, golden cheesy edges and a rich, gooey interior, fontina sheet pan mac and cheese is the dish for you. By baking this beloved comfort food on a sheet pan, you maximize the surface area, creating plenty of caramelized, crunchy bites. Fontina cheese brings a luxurious melt and subtle nutty flavor that sets this recipe apart. Before you start, be sure you have a large rimmed baking sheet and all your ingredients prepped, as sheet pan mac and cheese comes together quickly once you begin.
What You’ll Need
- 1 pound dried elbow macaroni or small pasta shells
- 4 tablespoons unsalted butter
- 1/4 cup all-purpose flour
- 3 cups whole milk (or 2%, but not skim)
- 1 cup heavy cream (for extra richness; substitute with more milk if desired)
- 8 ounces fontina cheese, grated
- 4 ounces sharp cheddar cheese, grated
- 2 ounces parmesan cheese, grated
- 1 teaspoon Dijon mustard
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon kosher salt (plus more for pasta water)
- 1/4 teaspoon black pepper
- 1/2 cup panko breadcrumbs
- 2 tablespoons olive oil or melted butter (for toasting breadcrumbs)
- Optional: fresh herbs, such as thyme or chives, for garnish
- Large rimmed sheet pan (about 18×13 inches)
- Large pot for boiling pasta
- Medium saucepan for cheese sauce
Step-by-Step
- Preheat the oven. Set your oven to 425°F (218°C) so it’s hot and ready for baking when you assemble the dish.
- Cook the pasta. Bring a large pot of salted water to a boil. Add the macaroni and cook until just shy of al dente, about 1-2 minutes less than package directions. (It will finish cooking in the oven.) Drain and set aside.
- Make the cheese sauce. In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes to remove the raw flour taste, stirring constantly. Slowly whisk in the milk and cream, ensuring no lumps form. Continue whisking until the mixture thickens and bubbles, about 4-6 minutes.
- Add the cheese and seasonings. Remove the saucepan from the heat. Stir in the Dijon mustard, garlic powder, onion powder, salt, and pepper. Add the fontina, cheddar, and half the parmesan cheese, stirring until smooth and fully melted.
- Combine pasta and sauce. In a large bowl, pour the cheese sauce over the drained pasta. Stir gently to coat all the noodles evenly.
- Prepare the sheet pan. Lightly grease your rimmed baking sheet with butter or nonstick spray. Evenly spread the sauced pasta onto the sheet pan, smoothing it into a single layer for maximum crispy edges.
- Make the breadcrumb topping. In a small bowl, toss panko breadcrumbs with olive oil or melted butter and the remaining parmesan cheese. Sprinkle the mixture evenly over the pasta.
- Bake. Place the sheet pan in the oven and bake for 20-25 minutes, or until the cheese is bubbling and the top is deeply golden brown. If you want extra browning, broil for an additional 2-3 minutes, watching carefully.
- Finish and serve. Remove from the oven and let cool for 5 minutes. Garnish with fresh herbs if desired. Cut into squares or scoop with a spatula and serve hot for the best texture.
Common Mistakes
- Overcooking the pasta: Fully cooked pasta can turn mushy after baking. Undercook by 1-2 minutes for the best bite.
- Using pre-shredded cheese: Pre-shredded cheeses contain anti-caking agents that can make the sauce grainy instead of creamy. Grate cheese fresh for best results.
- Skipping the roux: The flour-butter base thickens the sauce and prevents it from separating. Don’t skip this step.
- Piling pasta too thickly on the pan: For maximum crispy edges, spread the pasta in a thin, even layer on the sheet pan.
- Forgetting to season: Cheese sauce needs enough salt and seasoning to avoid blandness, especially since pasta absorbs flavor.
Tips
- Try a cheese blend: Fontina melts beautifully, but combining it with cheddar and parmesan gives more depth and sharpness. For a twist, add gruyère or mozzarella.
- Add-ins: Fold in cooked bacon, sautéed mushrooms, or roasted broccoli for extra flavor and texture.
- Make ahead: Assemble the mac and cheese up to the baking step, cover, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time if baking from cold.
- For gluten-free: Use gluten-free pasta and a 1:1 gluten-free flour blend for the roux. Use gluten-free breadcrumbs for the topping.
- Get even crisping: Rotate the sheet pan halfway through baking to ensure all edges brown evenly, especially if your oven heats unevenly.
- Customize the topping: Mix in smoked paprika, cayenne, or finely chopped herbs with the breadcrumbs for an extra flavor punch.
- Storage: Leftovers keep well in the fridge for up to 3 days. Reheat on a sheet pan in a 350°F oven for best texture, rather than microwaving.
Troubleshooting
- Sauce is grainy or separated: This can happen if the cheese is added to liquid that’s too hot, or if pre-shredded cheese is used. Always add cheese off the heat and stir until just melted. For a smoother sauce, strain it before adding to the pasta.
- Mac and cheese is dry: If the finished dish seems dry, it’s often due to overbaked pasta or not enough sauce. Next time, undercook the pasta more or increase the amount of cheese sauce. Drizzle a little warm milk over leftovers and reheat to restore creaminess.
- No crispy edges: Make sure the pasta is spread in a single, thin layer. Crowding the pan prevents browning. If still not crisp enough, broil for 2-3 minutes at the end, keeping watch to avoid burning.
- Breadcrumbs burn: If your oven runs hot or you broil too long, breadcrumbs may scorch. Cover loosely with foil if browning too quickly, or toast the breadcrumbs separately and add after baking.
- Flavor is bland: Taste the cheese sauce before adding to pasta and adjust salt or mustard as needed. Use sharper cheeses for more pronounced flavor.
Frequently Asked Questions
- Can I use only fontina cheese?
- Yes, but blending with cheddar and parmesan deepens flavor and improves texture. All-fontina mac and cheese will be milder and more gooey.
- What’s the best pasta shape for sheet pan mac and cheese?
- Elbow macaroni is classic, but small shells, cavatappi, or penne also work well. Choose a shape with plenty of nooks for holding sauce.
- Can I double the recipe?
- Yes, but use two sheet pans and rotate them halfway through baking. Overcrowding one pan will prevent crisping.
- Is it possible to make this ahead and freeze?
- You can assemble and freeze before baking. Thaw overnight in the fridge, then bake as directed, adding 10-15 minutes to the time.
- How do I get extra crispy edges?
- Spread the pasta in as thin a layer as possible, and finish with a few minutes under the broiler for maximum crunch.
- What should I serve with sheet pan mac and cheese?
- A simple green salad, roasted vegetables, or grilled chicken pairs well, balancing the richness of the dish.
