Ingredients for 9x9 mac and cheese

Ten essential ingredients transform into the perfect 9x9 mac and cheese with crispy edges and creamy centers.

The cheeses are non-negotiable here. Sharp cheddar provides the bold flavor, while Monterey Jack adds creaminess without overpowering. For the best quality, Whole Foods or specialty cheese shops carry aged cheddar with superior texture. If you're using pre-shredded cheese, avoid the anti-caking agents—they make the sauce grainy. Freshly shredded is always better. The heavy cream and butter should be cold when added to prevent early melting during the two-stage baking process. For the pasta, De Cecco or Barilla brands hold up best during baking without turning mushy.

No sharp cheddar? Pepper Jack or Gruyère work in a pinch, though the flavor profile shifts slightly. Running low on heavy cream? Half-and-half plus extra butter mimics the richness. The mustard adds depth—if you're avoiding tang, skip it entirely. For the breadcrumbs, Japanese panko is ideal, but regular breadcrumbs toasted in the oven work too. The flour is critical for the roux; King Arthur or Bob's Red Mill brands create a smooth sauce. If you're watching calories, you can reduce the butter slightly, but don't skip it entirely—it's what creates that velvety texture. The two-stage baking relies on proper cheese melting, so ensure your cheeses are freshly shredded and room temperature before combining.

This casserole reheats beautifully—just cover with foil and bake at 350°F for 15 minutes. For make-ahead convenience, assemble the dish one day ahead and refrigerate uncovered. The next day, bake as directed for 45-50 minutes to achieve the same crispy top. Store leftovers in an airtight container for up to 5 days, though the texture softens slightly after the first day. For serving, use a serrated knife dipped in hot water to slice cleanly through the crispy crust. The dish freezes well for up to 3 months—thaw overnight in the fridge before reheating.

Step-by-step instructions for 9x9 mac and cheese

Master the perfect balance of crispy top and gooey interior with this foolproof method.

Bring a large pot of water to a rolling boil and add 2 cups elbow macaroni. Season generously with salt—it should taste like the ocean. Cook for 8-9 minutes until the pasta is al dente, with a slight bite remaining. You'll want to drain it just before it's fully tender so it continues cooking in the oven and absorbs the cheese sauce beautifully.

Drain the pasta in a colander, then immediately rinse under cold water for 10 seconds to stop the cooking process. This prevents the pasta from becoming mushy when mixed with the cheese sauce. Use a rubber spatula to transfer the drained pasta to a large mixing bowl—you'll be adding everything to this same bowl, so no need to wash it.

In the same bowl with the cooked pasta, add 2 cups sharp cheddar cheese and 1 cup monterey jack cheese. Use your hands to break up any large cheese clumps and distribute it evenly throughout the pasta. The heat from the pasta will begin melting the cheese immediately, creating a creamy base.

In a separate saucepan, melt 0.5 cup unsalted butter over medium heat. Whisk in 0.25 cup all-purpose flour to form a roux, cooking for 1-2 minutes until it turns a pale golden color. Slowly pour in 0.5 cup whole milk and 0.5 cup heavy cream while whisking continuously to prevent lumps from forming. Bring the mixture to a gentle simmer for 3-4 minutes until it thickens enough to coat the back of a spoon.

Pour the cheese sauce over the pasta and cheese mixture in the bowl. Stir vigorously to combine completely, breaking up any remaining cheese clumps. The sauce should coat every strand of pasta evenly. Add 1 tbsp yellow mustard, 1.5 tsp diamond crystal kosher salt, and 0.5 tsp freshly ground black pepper, mixing well to distribute the seasoning throughout.

Here's where the magic happens: use a wooden spoon to press the mixture against the sides of the bowl, scraping up any cheese that sticks. This ensures every bite gets that perfect cheesy flavor. The mixture should be thick but still pourable—if it's too stiff, add 1-2 tablespoons of milk or cream to loosen it.

Preheat your oven to 350°F. Grease a 9x9-inch baking dish thoroughly with butter or cooking spray—this prevents sticking and makes cleanup a breeze. Transfer the mac and cheese mixture to the prepared dish, spreading it out evenly. The dish should be about ¾ full—don't overfill it.

For that coveted crispy top, sprinkle 0.25 cup panko breadcrumbs evenly over the surface. Press down gently with your fingers to ensure they adhere to the top. Bake for 25-30 minutes until the edges are bubbling and the top is golden brown. If the top browns too quickly, tent loosely with aluminum foil to prevent burning while the center finishes cooking.

Remove the baking dish from the oven and let it rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly, making it easier to cut and preventing a runny mess. The internal temperature should reach 165°F—use an instant-read thermometer to check if you're unsure.

Use a sharp knife to cut into 6 equal squares for serving. Each bite should deliver that perfect combination of crispy, golden-brown top with molten, cheesy interior. The edges should be slightly caramelized, while the center remains rich and gooey. Serve immediately while hot, and enjoy the ultimate comfort food experience.

Essential equipment for perfect results

Baking Dish Essentials

The 9x9-inch baking dish is non-negotiable for this recipe—it ensures even baking and that perfect crispy edge-to-gooey center ratio. I recommend using a ceramic or glass dish (like Pyrex) because they distribute heat evenly and prevent sticking.

Avoid dark-colored metal dishes—they can over-brown the edges while the center stays undercooked. Always grease it thoroughly with butter or baking spray before adding your mac and cheese mixture. 🧈

Mixing Bowl Must-Haves

A large, deep mixing bowl (at least 8-quart capacity) is crucial for combining all ingredients without spills. I love using stainless steel bowls (like OXO Good Grips) because they’re durable and easy to clean.

The bowl should have sloped sides to help scrape up every last bit of cheese sauce—this ensures no dry pasta strands remain. Avoid plastic bowls, as they can’t handle the heat from the pasta and cheese mixture. 🍲

Essential Tools for Sauce

For the cheese sauce, you’ll need a medium saucepan (2-3 quart) and a whisk to create a smooth roux. I prefer copper-bottomed pans (like All-Clad) for even heat distribution, but any heavy-bottomed pan works.

A wooden spoon is perfect for pressing the mixture against the bowl’s sides to incorporate melted cheese. If you’re short on time, an immersion blender can help break up cheese clumps without overworking the sauce. 🥄

Crispy Top Secrets

The panko breadcrumbs topping requires a fine-mesh sieve (like Microplane) to distribute them evenly. Press them down gently with your fingers or the back of a spoon to ensure they stick.

For extra crispiness, toast the panko in a dry pan over medium heat for 2-3 minutes before adding it to the dish. A pizza stone in your oven can also help achieve a crisper, more even crust. 🍞

Temperature Control Tools

An instant-read thermometer (like Thermoworks Thermapen) is the only way to guarantee your mac and cheese reaches 165°F safely. Place it in the center of the dish before baking to monitor progress.

For the broiler step, position your oven rack 4-5 inches from the heat source to avoid burning the top. A heat-resistant spatula (like OXO Good Grips) helps transfer the hot dish safely from oven to table. 🌡️
