Ingredients for 9x9 mac and cheese

Pantry staples that transform into golden, bubbling perfection in one pan—crispy on top, gooey inside.

The cheeses make or break this dish—sharp cheddar for bite and Monterey Jack for creaminess. Grab pre-shredded from the dairy aisle (it's less clumpy), or shred your own from blocks for the best texture. I always buy Kraft sharp cheddar for consistency—it's the golden standard in grocery stores. For the breadcrumbs, Panko from Trader Joe's gives the best crispy topping, but any panko will work. The pasta? Barilla elbow macaroni is my go-to—it holds up perfectly during baking without getting mushy.

No sharp cheddar? Extra sharp cheddar at half the amount works in a pinch. Monterey Jack hard to find? Colby Jack is a decent swap. Heavy cream too rich? Half-and-half or whole milk keeps it creamy without overpowering. The mustard powder is non-negotiable—it cuts through the richness and adds that signature tang. Fresh garlic powder? Toast your own garlic powder for deeper flavor, but store-bought is fine. For the breadcrumb topping, crushed cornflakes add a fun texture twist if you're feeling adventurous.

This reheats like a dream—just cover with foil and bake at 350°F for 10-15 minutes. Keeps 3-4 days in the fridge, 2 months frozen. I always make a double batch because it's that good. The secret to freezing? Portion into squares before freezing—just pop one in the oven when you're ready. The crispy topping stays crispy when reheated properly, and the cheese stays gloriously melty. Trust me, you'll be making this every weeknight.

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

Here's how to create that perfect crispy-topped, gooey masterpiece in your 9x9 pan.

Bring a large pot of water to a rolling boil and salt it generously—it should taste like the ocean. Add the 2 cups elbow macaroni and cook until it's 1 minute before the package directions call for al dente. This slight undercooking prevents mushiness when combined with the cheese sauce later.

Drain the pasta in a colander, but don't rinse it—those starchy strands are what help create that silky sauce. While the pasta cooks, I like to warm the 0.5 cup whole milk in a small saucepan over low heat until it's just steaming. This prevents temperature shock when we combine it with the other ingredients later.

In the same 9x9 baking dish you'll use later, melt the 0.5 cup unsalted butter over medium heat until it's completely liquid. Add the 0.25 cup all-purpose flour and whisk constantly for 1-2 minutes until you have a smooth, thick paste—this is your roux. The reason we do this in the baking dish is to minimize cleanup later.

Gradually whisk in the warmed whole milk and 0.5 cup heavy cream, making sure to scrape up any browned bits from the bottom of the pan. Then add the 1.5 cups sharp cheddar cheese and 1 cup monterey jack cheese, stirring constantly until the cheese melts completely. The sauce should be thick and glossy, coating the back of a spoon. If it's too thick, whisk in 1-2 tablespoons of pasta water later.

Add the drained elbow macaroni to the cheese sauce and gently fold everything together using a rubber spatula. Stir in the 0.5 tsp mustard powder, 0.5 tsp garlic powder, 1.5 tsp salt, and 0.5 tsp black pepper. The mustard powder adds that perfect tangy kick that makes this mac and cheese sing.

Here's the thing—don't overmix. You want the pasta to be coated in the sauce but still have some distinct pieces. The mixture should be thick enough to hold its shape when you spoon it out, but still have that melt-in-your-mouth texture. Taste it now—you'll want to adjust seasoning if needed, adding more salt or pepper as necessary.

In a small bowl, mix together the 0.5 cup panko breadcrumbs and 1 tbsp extra-virgin olive oil until the crumbs are evenly coated. Spread this mixture evenly over the top of the mac and cheese, pressing down gently with the back of a spoon. This creates that magical crispy crust that everyone loves.

Here's a pro tip: I like to make a small well in the center of the breadcrumb mixture. This helps the breadcrumbs crisp up more evenly and prevents them from sinking into the cheese. The oil in the breadcrumbs will create that golden, crunchy topping that contrasts perfectly with the creamy interior.

Transfer the baking dish to a preheated 375°F oven and bake for 20-25 minutes until the top is golden brown and the edges are bubbling. You'll know it's ready when the cheese is melting beautifully and the breadcrumb topping has turned a delicious golden color.

Let the mac and cheese rest for 5-10 minutes before serving—this allows the cheese to set slightly and makes it easier to cut. The contrast between the crispy breadcrumb topping and the creamy, gooey cheese underneath is what makes this dish so irresistible. Serve immediately with a side of steamed broccoli or a simple green salad.
