Ingredients for baked macaroni and cheese recipe with eggs and milk

Pantry staples plus a few key ingredients create this crispy-topped breakfast casserole that's rich and satisfying.

The sharp cheddar is non-negotiable here—Kraft or Cabot shreds perfectly, but local cheesemongers often have even better options. Grab the medium sharpness for that perfect balance of tang and creaminess. The eggs need to be room temperature, so take them out 30 minutes before cooking. For the macaroni, elbow shapes work best—they hold up better during baking. If you can't find elbow, penne or cavatappi are solid substitutes. The onion and garlic should be finely diced—small pieces ensure even cooking without bitterness.

No sharp cheddar? Gruyère or Monterey Jack work beautifully, though the flavor will differ slightly. Running short on eggs? Replace one with 2 tbsp cornstarch—it adds structure without altering the taste. The milk can be swapped for half-and-half or heavy cream for extra richness, but stick with whole milk for the best texture. If you're making this ahead, pre-shredded cheese is fine, but freshly grated melts more smoothly. The breadcrumbs? Panko is best—regular breadcrumbs get soggy. For extra crunch, toast them lightly in the oven before adding.

This casserole reheats beautifully—350°F for 15-20 minutes restores that crispy top perfectly. Store leftovers covered in the fridge for 4-5 days, or freeze portions for up to 3 months. For meal prep, assemble the dish without baking, then refrigerate overnight before baking in the morning. The flavors meld beautifully overnight, making it even more delicious. To keep the top extra crispy, broil for 2-3 minutes at the end of baking.

Step-by-step instructions for baked macaroni and cheese

Here's how to create a rich, creamy breakfast casserole with a perfectly crispy top.

Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Cook according to package directions until 1 minute before al dente—this ensures it finishes cooking in the oven without becoming mushy. Drain thoroughly in a colander and rinse briefly with cold water to stop the cooking process immediately.

Real talk: Don't overcook the pasta here. You want it firm enough to hold its shape when baked, but still tender. I press a piece between my fingers to test—it should give slightly but not fall apart. Drain completely to prevent a watery casserole.

In a large skillet over medium heat, melt ½ cup unsalted butter until foaming. Add the 1 whole yellow onion and 2 cloves garlic cloves (minced), cooking for 5-6 minutes until softened and fragrant. This aromatic base forms the flavor foundation.

Reduce heat to low and whisk in 2 tbsp all-purpose flour, cooking for 1 minute to remove the raw flour taste. Slowly pour in 2 cups whole milk while whisking constantly to prevent lumps. Bring to a gentle simmer and cook for 3-4 minutes until thickened slightly.

Remove from heat and stir in 2 cups sharp cheddar cheese until completely melted and smooth. The sauce should be velvety with no graininess. If it's too thick, add 1-2 tablespoons milk to reach a pourable consistency. Season with 1.5 tsp salt and ½ tsp black pepper.

In a large mixing bowl, combine the cooked elbow macaroni with the cheese sauce. Stir gently but thoroughly to ensure every noodle is coated. Add 4 whole large eggs (room temperature) and mix until fully incorporated. The batter should be thick but still pourable.

Here's the thing—don't overmix. You want a few streaks of egg visible, as this helps create that signature creamy texture. Transfer the mixture to a greased 9x9-inch baking dish, spreading evenly to the edges. This even distribution ensures consistent baking.

In a small bowl, combine ¼ cup panko breadcrumbs and ¼ cup freshly grated parmesan cheese. Sprinkle this mixture evenly over the top of the casserole, pressing down gently to help it adhere. The panko will create that coveted crispy texture we're after.

Bake in a preheated 375°F oven for 25-30 minutes until the top is deep golden brown and the center reaches 165°F on an instant-read thermometer. You'll know it's ready when the edges pull away slightly from the pan and the top has a satisfying crunch.

Don't skip the rest: Let the casserole sit for 5 minutes before serving. This allows the internal heat to distribute, ensuring every bite is perfectly creamy and hot. The crispy top will soften slightly but still provide that delightful textural contrast.

Make-ahead tips for this recipe

Prep Ahead Strategy

Assemble the entire casserole the night before—just mix the pasta, cheese sauce, and eggs in your baking dish, then refrigerate uncovered. The cold helps the flavors meld beautifully overnight, and the top stays crispier when baked fresh in the morning.

I swear by this method for restaurant-quality results with minimal morning effort. 💫

Freezer-Friendly Assembly

For meal prep, combine all ingredients except the breadcrumb topping in a freezer-safe baking dish. Cover tightly with plastic wrap and freeze for up to 3 months.

When ready to bake, thaw in the fridge overnight, add the breadcrumb mixture, and bake as directed. The texture remains rich and creamy, just like fresh.

Crispy Top Hack

Toast ¼ cup panko breadcrumbs in a dry skillet over medium heat for 2 minutes before mixing with parmesan. The extra toastiness creates an irresistible crunch that holds up perfectly when reheated. I always do this step—it’s a game-changer for leftovers. 🔥

Reheating Secrets

For best results, cover the baked casserole with foil and reheat at 350°F for 15-20 minutes. The foil traps heat to restore that crispy top, while the foil-free final 2 minutes at broil ensures a golden finish. Avoid microwaving—it turns the top soggy every time.

Portion Control

Divide baked casserole into single-serving portions before freezing or refrigerating. Store in airtight containers with parchment paper between layers to prevent sticking. When reheating, bake covered at 375°F for 10-12 minutes—just enough to warm through without drying out.

Make-Ahead Timeline

Here’s my foolproof schedule: Night before, cook pasta, make sauce, and assemble. Morning of, bake at 375°F for 25-30 minutes—perfect for brunch crowds.

For weeknight prep, assemble after work, refrigerate overnight, then bake straight from the fridge (add 5-10 extra minutes to baking time). Timing is everything! ⏰
