Ingredients for baked macaroni and cheese recipe with eggs and milk

Six hearty ingredients transform into breakfast magic—creamy, crispy, and ready in under an hour.

The cheese is non-negotiable here. Sharp cheddar gives that perfect tang, but Monterey Jack or Gruyère from the deli counter at Whole Foods adds depth. I always grab the block and grate it myself—pre-shredded gets gummy. For the macaroni, elbow shape is key (medium or small), but any short pasta works in a pinch. The eggs? Room temperature makes all the difference—they bind better and won't curdle. Pro tip: Costco sells them in bulk for meal prep days.

No sharp cheddar? Colby Jack or pepper jack still delivers flavor—just add a pinch more salt. Short on milk? Heavy cream at half the amount makes it richer, but whole milk keeps it light. The butter matters too—European-style (like Plugrá) has more fat, so use it if you're watching calories. For extra crunch, toast the breadcrumbs in a dry pan for 30 seconds before topping. And if you're feeling fancy, swap the onion for leeks or shallots—they add sweetness without overpowering.

This reheats like a dream—3 minutes at 350°F or straight from the fridge. Keeps for 4 days in the fridge, 3 months frozen (portion into single servings first). For meal prep, I always make a double batch—one for breakfast, one for lunch. The leftovers? Even better the next day as the flavors meld. Store in an airtight container with parchment between layers to keep it moist.

Step-by-step instructions for baked macaroni and cheese with eggs and milk

Here's how to create a creamy, cheesy breakfast casserole that's ready in under an hour.

Bring a large pot of water to a rolling boil and add 1.5 pounds of elbow macaroni. Cook according to package instructions until al dente—about 1 minute less than recommended. This ensures the pasta stays firm when baked. Drain immediately and rinse under cold water to stop the cooking process and remove excess starch.

I like to give the pasta a quick shake in the colander to break up any clumps before transferring it to a large mixing bowl. This prevents uneven texture in the final dish. The pasta should be hot but not steaming when you add it to the cheese mixture—this helps create that perfect creamy consistency.

In a separate saucepan, melt 0.5 cup of unsalted butter over medium heat. Add the 1 whole diced yellow onion and 3 minced garlic cloves, cooking for 3-4 minutes until softened and fragrant. Here's the thing—don't let the garlic brown or it'll turn bitter.

Reduce heat to low and whisk in 0.25 cup of all-purpose flour, cooking for 1 minute to remove the raw flour taste. Slowly pour in 1.5 cups of whole milk while whisking constantly to prevent lumps. Add 1.5 teaspoons of kosher salt and 0.5 teaspoon of ground black pepper, then stir in 2 cups of freshly grated sharp cheddar cheese until fully melted and smooth.

Add the cooked macaroni to the cheese sauce and stir until every strand is completely coated. This is where the magic happens—the residual heat from the pasta helps melt any remaining cheese and creates that signature velvety texture. If the mixture seems too thick, add 2-3 tablespoons of milk to loosen it.

Transfer the pasta mixture to a greased 9x13-inch baking dish. I use a rubber spatula to scrape every last bit from the bowl—no one wants dry macaroni in their casserole. The dish should be about ¾ full—this gives the casserole room to puff up slightly during baking.

In a medium bowl, whisk together the 4 whole large eggs until frothy. This helps create a lighter texture in the final dish. Pour the eggs evenly over the macaroni mixture in the baking dish and gently stir to combine. The eggs will start to set slightly, which helps hold everything together during baking.

Sprinkle 0.25 cup of panko breadcrumbs and 0.25 cup of freshly grated parmesan cheese evenly over the top. This creates a delicious crispy crust while adding extra flavor and texture. For best results, press down gently on the breadcrumb mixture to help it adhere to the top layer.

Preheat your oven to 375°F while you assemble the casserole. Bake uncovered for 25-30 minutes until the top is golden brown and the edges are bubbling. The center should still be slightly jiggly—it'll continue cooking after you remove it from the oven.

For the final touch, broil for 1-2 minutes until the top is deeply golden and slightly crispy. Watch it closely to prevent burning. Let the casserole rest for 5 minutes before serving—this allows the eggs to fully set and makes it easier to slice. Cut into squares and enjoy this comforting dish hot from the oven!

Pro cooking tips for great baked macaroni and cheese recipe with eggs and milk

Egg Binding Secrets

Room-temperature eggs are your best friend here—they blend more smoothly into the pasta mixture and prevent curdling. I like to whisk them vigorously for about 30 seconds until slightly frothy, which helps distribute them evenly.

This creates a lighter, more custard-like texture rather than a heavy, eggy center. If your eggs are straight from the fridge, let them sit at room temperature for 15-20 minutes before using. 🥚

Cheese Melting Mastery

Freshly grated cheese makes all the difference—pre-shredded contains anti-caking agents that make the sauce grainy. Use a box grater for sharp cheddar, and stir it into the sauce over low heat until completely melted.

If your cheese separates, whisk in 1 tablespoon of milk at a time until smooth. For extra richness, I sometimes add ¼ cup of cream cheese to the sauce before combining with pasta.

Pasta Prep Pro Tips

Cook your macaroni just shy of al dente—about 1 minute less than package instructions. This prevents mushiness when baked. After draining, rinse with cold water to stop cooking and remove excess starch.

I also recommend shaking the pasta in the colander to break up any clumps before mixing with the cheese sauce. This ensures every bite has that perfect creamy texture. 🍝

Oven Temperature Control

Don't skip preheating your oven—this ensures even cooking and that perfect golden crust. Bake at 375°F for 25-30 minutes, then broil for 1-2 minutes for extra crispiness.

If your top isn't browning enough, try placing the baking dish on the middle rack and increasing oven temp to 400°F for the last 5 minutes. Keep a close eye to avoid burning.

Crust Perfection

The breadcrumb topping should be pressed gently but firmly onto the surface to create that satisfying crunch. For extra flavor, mix the panko with 1 teaspoon of garlic powder or ½ teaspoon of smoked paprika before sprinkling.

I also recommend toasting the breadcrumbs in a dry pan for 30 seconds before adding them to enhance their crunch. This simple step elevates the dish from good to restaurant-quality. 💫

Resting for Success

Never skip the 5-minute rest after baking—this allows the eggs to fully set and makes slicing much easier. The casserole will continue cooking slightly during this time, ensuring the center reaches a safe temperature.

If you're short on time, let it rest for at least 3 minutes, but don't rush it. Patience here prevents a runny center and makes clean slices possible. Trust me, it's worth the wait! ⏰
