Baked Mac and Cheese Recipe 8x8 Pan: Crispy Top, Melty Streaks, One-Pan Wonder

This baked mac and cheese recipe in an 8x8 pan delivers restaurant-quality comfort food with a crispy golden top and gooey, melty streaks throughout. 💛 The secret lies in the perfect cheese blend and a simple layering technique that ensures every forkful is creamy, cheesy, and satisfying—no fancy equipment required.

I developed this version after years of testing, and it's become my go-to for feeding a crowd without the fuss of individual baking dishes.

The beauty of this recipe is its simplicity: just five core ingredients (plus your choice of add-ins) come together in one 8x8-inch baking dish for a foolproof method that works every time.

The key to achieving that crispy top while keeping the inside lusciously creamy is baking at 375°F for about 30-40 minutes, with a final broil to set the edges just right. I promise, once you try this version, you'll never go back to boxed mac and cheese again.

What sets this apart is the balance of textures—crispy edges that give way to tender, cheesy layers beneath. The cheese sauce is rich but not overly heavy, thanks to a touch of mustard powder for depth and a splash of milk for smoothness.

Whether you're serving it as a side dish or making it the star of the meal, this mac and cheese is guaranteed to disappear faster than you can say "extra cheese."

For extra flavor, consider adding cooked bacon, pulled chicken, or a sprinkle of smoked paprika before baking. The possibilities are endless, but the foundation remains the same: crispy top, melty center, and a dish that feels like a warm hug in every bite. Let's get baking!

Ingredients for baked mac and cheese recipe 8x8 pan

Five core ingredients plus a few pantry staples—this is your all-in-one mac and cheese kit.

The cheeses are non-negotiable for that perfect balance. Sharp cheddar gives the bite, while Monterey Jack keeps it creamy and mild. Trader Joe's has pre-shredded blends that work great, but if you're grating yourself, use a box grater for finer, more even shreds. The Parmesan adds a nice umami punch—don't skip it. For the pasta, Barilla or De Cecco are my go-tos, but any elbow macaroni will do. Just make sure it's dry and not pre-boiled—we're cooking it fresh in the dish.

No sharp cheddar? Extra sharp works too, but cut back slightly on salt. Heavy cream too expensive? Half-and-half or whole milk will work, though the texture might be slightly lighter. The mustard powder is key—it cuts through the richness and adds depth. If you're adding extras like bacon or chicken, cook them first and fold in before baking. The Panko on top is what gives you that crispy crust, so don't skimp. Pro tip: Toast the Panko in a dry pan for 2 minutes before sprinkling for extra crunch.

This dish reheats beautifully—just cover with foil and warm in the oven at 350°F for 15 minutes. It actually tastes better the next day, as the flavors meld even more. Store leftovers in the fridge for up to 5 days, covered tightly. For freezing, portion into individual servings and freeze for up to 3 months. The crispy top gets soggy if reheated too long, so keep an eye on it. I always make a double batch—one for dinner, one for lunches the next week.

Step-by-step instructions for baked mac and cheese in an 8x8 pan

Here's how to make the ultimate baked mac and cheese with that perfect crispy top and gooey center.

Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Cook until 1 minute before the package directions for al dente—you want it to finish cooking in the oven. Drain in a colander and rinse briefly with cool water to stop the cooking process. Shake off any excess water and return the pasta to the pot.

Here's the thing—rinsing too much removes starch that helps bind the sauce. Just a quick rinse is all you need. While the pasta cooks, preheat your oven to 350°F so it's ready when you are. This temperature ensures the mac and cheese bakes through without burning the top.

In a separate saucepan, melt 0.5 cup unsalted butter over medium heat. Once melted, whisk in 0.25 cup all-purpose flour to create a roux. Cook for 1-2 minutes until it turns a light golden color—this is your flavor foundation. Slowly whisk in 1.5 cups whole milk and 1 cup heavy whipping cream, letting each addition cook for 30 seconds before adding more.

Reduce heat to low and stir constantly for 5-7 minutes until the sauce thickens enough to coat the back of a spoon. Now add 2 cups sharp cheddar cheese, 1.5 cups monterey jack cheese, 1 tsp mustard powder, 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder. Stir until completely melted and smooth—this should take about 2-3 minutes over gentle heat.

Pour the hot cheese sauce over the cooked elbow macaroni in the pot. Stir vigorously for 1-2 minutes until every noodle is fully coated. The sauce should look glossy and completely enveloped the pasta. If it's too thick, add 2-3 tablespoons of the pasta water to loosen it to a creamy consistency.

Here's where the magic happens: transfer the macaroni mixture to your greased 8x8-inch baking dish. Spread it out evenly, creating a smooth surface. This even distribution ensures the cheese melts uniformly and the top gets that perfect crispy texture we're after.

In a small bowl, mix together 0.25 cup panko breadcrumbs and 0.25 cup parmesan cheese. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently with a spatula. This creates the crispy crust we all love—don't skip this step if you want that satisfying crunch!

Pop the baking dish into the 350°F oven and bake for 25-30 minutes until the edges are bubbly and the top is deep golden brown. You'll know it's ready when the cheese is fully melted with beautiful streaks and the top has that irresistible crispiness. If it starts to brown too quickly, tent loosely with aluminum foil to prevent burning.

Remove the mac and cheese 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 serve. The internal temperature should reach 165°F—this ensures it's safe to eat while maintaining that perfect creamy texture.

Cut into squares and serve immediately. The contrast between the crispy top and the creamy, cheesy center is what makes this baked mac and cheese truly special. Pair it with a simple green salad or some crusty bread for the ultimate comfort food experience!

Storing and reheating your leftovers

Refrigerator Storage

Let your baked mac and cheese cool completely before transferring it to an airtight container—I swear by Pyrex glass containers with snap-on lids. Store it in the fridge for up to 4 days, but honestly, it tastes even better the next day as the flavors meld together.

The crispy top stays crispier if you press plastic wrap directly on the surface before sealing the container. 💛

Freezer Prep Tips

For long-term storage, portion your mac and cheese into single-serving sizes before freezing. I use quart-size freezer bags because they lay flat and thaw faster than bulky containers. Leave 1 inch of headspace for expansion, and squeeze out excess air to prevent freezer burn.

Label with the date—this dish freezes beautifully for up to 3 months!

Oven Reheating

My favorite method is reheating in the oven at 350°F for 15-20 minutes, covered loosely with aluminum foil. This keeps the crispy top intact while warming the creamy center evenly.

For extra crispiness, broil for 1-2 minutes at the end—just watch it closely to avoid burning. The texture comes back better than microwave reheating, trust me!

Microwave Shortcuts

When you're in a rush, cover the mac and cheese with a damp paper towel before microwaving on 50% power for 2-3 minutes. Stir halfway through, then add 1-2 tablespoons of milk or cream to restore creaminess.

If it looks dry, tent with another damp paper towel and microwave in 30-second bursts until heated through. 🔥

Crispy Top Rescue

If your reheated mac and cheese loses its crispy top, don't worry! Sprinkle 1 tablespoon of breadcrumbs on top and broil for 1-2 minutes until golden. This works like a charm for restoring that satisfying crunch. For extra flavor, add a pinch of smoked paprika or garlic powder before broiling.

Make-Ahead Magic

I always make a double batch—one for dinner, one for lunches the next week. The flavors actually deepen overnight, making it perfect for meal prep. Just store leftovers in the fridge and reheat portions as needed.
