The best part? You can customize it with add-ins like bacon, jalapeños, or extra cheese to suit any taste. Let's get started on creating this breakfast casserole that's anything but ordinary.
Ingredients for baked mac and cheese recipe with egg and milk
Twelve ingredients transform ordinary mac and cheese into a crispy-topped breakfast sensation.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lbs | Dry, medium or jumbo size |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, aged 6 months minimum |
| Large Eggs 🥚 | 4 whole | Room temperature for blending |
| Whole Milk 🥛 | 1 ½ cups | Full-fat for creaminess |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for even melting |
| All-Purpose Flour 🌾 | ¼ cup | For crispy topping texture |
| Breadcrumbs 🍞 | ¼ cup | Panko for extra crunch |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For savory depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked black pepper |
| Bacon (optional) 🥓 | ½ lb | Cooked and crumbled |
| Butter (for baking dish) 🧈 | 1 tbsp | Melted for greasing |
The cheese is everything here—aged sharp cheddar melts perfectly and delivers that signature tang. Whole Foods or Trader Joe's carry excellent pre-shredded options, but if you've got time, shred your own from a block for better texture. Eggs should be room temperature when you mix them in—they blend smoother that way. For the pasta, elbow macaroni is classic, but medium or jumbo sizes hold up better to baking. Cook it al dente—it'll finish in the oven. The milk matters too: whole milk gives you that velvety texture you crave, while reduced-fat versions can make the dish feel dry.
No sharp cheddar? Monterey Jack or Gruyère work in a pinch, though the flavor won't be quite the same. Out of eggs? Sour cream at half the amount adds richness without changing the texture much. The butter in the topping can be swapped for olive oil if you're watching saturated fat. For the crispy crust, I like toasting the breadcrumbs with garlic powder and onion powder first—just 2 minutes in a dry pan makes all the difference. Want to skip the bacon? Try diced jalapeños or sun-dried tomatoes for a different flavor punch. The key is balancing the add-ins so they don't overpower the cheesy base.
This bakes up best in a 9x13-inch baking dish—don't skimp on the size. The butter you melt for greasing? Use it to coat the dish AND the top crust before baking. Leftovers keep 4 days in the fridge, but honestly, it reheats better the second day. For make-ahead magic, assemble the casserole in the dish, cover with foil, and refrigerate overnight. Bake straight from cold—it'll take 10-15 minutes longer but the texture is worth it. Portion into individual ramekins for single-serving crispy mac cups that reheat perfectly.

Step-by-step instructions for baked mac and cheese with egg and milk
Here's how to make this creamy, crisp-topped breakfast casserole that's ready in under an hour.
Cook the Elbow Macaroni Al Dente
Bring a large pot of water to a rolling boil and add 1.5 lbs elbow macaroni. Stir immediately to prevent sticking. Cook for 1 minute less than the package instructions suggest—this ensures the pasta finishes cooking in the oven and doesn't turn mushy. Drain the pasta in a colander and rinse briefly with cold water to stop the cooking process. I like to shake the colander gently to remove excess water, but don't overdo it—the pasta needs moisture to absorb the cheese sauce later.
While the pasta cooks, melt 0.5 cup unsalted butter in a large skillet over medium heat. If using the optional 0.5 lb bacon, add it now and cook until crispy. Drain on paper towels and crumble into small pieces. This bacon adds a smoky depth that makes the whole dish sing. Set aside for later.
Prepare the Creamy Cheese Sauce
In a large mixing bowl, combine the drained elbow macaroni, 2 cups sharp cheddar cheese, 1.5 cups whole milk, 1 tsp garlic powder, 1 tsp onion powder, 1.5 tsp salt, and 0.5 tsp black pepper. Stir well to distribute the cheese evenly—you want every strand of pasta coated in that melty goodness. If the mixture seems too thick, add 1-2 tablespoons of the pasta water to loosen it up. The sauce should be smooth but still cling to the noodles.
In a separate bowl, whisk together the 4 whole large eggs until the yolks and whites are fully combined. This ensures a uniform texture in the final dish. I like to add the eggs last so they don't start cooking prematurely from the heat of the pasta.
Combine and Assemble the Casserole
Preheat your oven to 375°F and grease a 9x13-inch baking dish with 1 tbsp melted butter. This prevents sticking and makes cleanup a breeze. Pour the macaroni mixture into the prepared dish and spread it out evenly. If you added bacon, sprinkle those crispy crumbles over the top now—they'll add texture and flavor in every bite.
Pour the egg mixture evenly over the top of the casserole. The eggs will create that signature creamy texture while also helping to bind everything together. For extra crispiness, I like to sprinkle the 0.25 cup breadcrumbs and 0.25 cup all-purpose flour mixture over the top. This creates a golden, crunchy crust that contrasts perfectly with the creamy interior.
Bake Until Golden and Bubbly
Place the baking dish on the middle rack of your oven and bake for 30-35 minutes. You're looking for a golden brown top that's crispy to the touch, with bubbling edges that indicate the cheese is fully melted. If the top browns too quickly, tent it loosely with aluminum foil to prevent burning while still allowing it to crisp.
About 5 minutes before the baking time is up, turn on your broiler for 2-3 minutes to get that perfect golden crust. Keep an eye on it—broilers can be aggressive, and you want a crispy top, not a burnt one. The internal temperature should reach 160°F when checked with an instant-read thermometer.
Rest and Serve Warm
Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting time allows the cheese to set slightly, making it easier to slice and serve. The dish will be hot, so use oven mitts or a thick towel to handle the baking dish.
Slice into 6 equal portions and serve immediately. The contrast of the crispy, golden top with the creamy, cheesy interior is what makes this dish so special. Pair it with a simple side salad or some crusty bread to soak up any extra cheese sauce. Leftovers keep well in the refrigerator for up to 3 days, and they reheat beautifully in the microwave or oven.

Make-ahead tips for this recipe
Overnight Prep Advantage
Assemble the entire casserole in your baking dish the night before—this is my secret for restaurant-quality texture. After mixing the pasta, cheese, and egg mixture, spread it in the dish, cover tightly with plastic wrap, and refrigerate overnight.
The flavors meld beautifully while the eggs firm up slightly, preventing a runny texture when you bake it the next day. 💫
Baking from Cold
When ready to bake, simply pop the chilled casserole into the oven at 375°F with no preheating needed. It'll take 10-15 minutes longer than fresh (about 45-50 minutes total), but the result is worth it—the crust becomes extra crispy while the interior stays perfectly creamy.
I like to add 5 extra minutes to the baking time when starting from cold.
Portioning for Meal Prep
Divide the fully baked mac and cheese into individual ramekins or small baking dishes for perfect single servings. Portion the hot casserole into 6-8 ramekins, sprinkle each with a little extra breadcrumb mixture, and refrigerate.
When reheating, bake at 350°F for 15-20 minutes—they'll develop crispy tops while staying creamy inside. These make great grab-and-go breakfasts!
Freezer-Friendly Method
For longer storage, assemble the casserole in a baking dish, cover tightly with aluminum foil, and freeze for up to 3 months.
When ready to eat, thaw overnight in the fridge, then bake at 375°F for 45-50 minutes (covered with foil for the first 30 minutes, then uncovered for browning). The texture remains creamy, though the crust may be slightly softer after freezing.
Reheating Leftovers
Store leftovers in an airtight container for up to 4 days. For best results, reheat in the oven at 350°F for 15-20 minutes covered with foil to prevent drying.
If using the microwave, cover with a damp paper towel and heat in 1-minute intervals at 50% power, stirring between each interval. The crispy top won't survive microwave reheating, but the creamy interior stays perfect.
Make-Ahead Serving Suggestions
Prep ahead for gatherings by assembling the casserole in a 9x13-inch dish, then refrigerate until ready to bake. For parties, bake it 15 minutes early, cover with foil, and keep warm in a 200°F oven while you finish other dishes.
The crispy top stays intact, and the cheese remains melty. I like to serve with garlic bread or a simple arugula salad to balance the richness. ✨

Frequently asked questions
Why does this recipe use both eggs and milk?
The eggs act as a natural binder, creating that signature creamy texture while helping the casserole hold together during baking. The milk adds richness and prevents the cheese from becoming too thick or grainy. Together, they create a velvety consistency that's much smoother than traditional mac and cheese recipes.
Can I make this recipe without eggs?
Yes, but the texture will be different. Replace the eggs with ½ cup sour cream or Greek yogurt to maintain creaminess. For binding, add 1 tablespoon cornstarch or flour to the cheese sauce. The crust may be slightly less crispy, but it'll still be delicious.
What's the secret to getting a crispy top?
The crispy crust comes from the combination of flour and breadcrumbs on top, plus the broiler at the end. Toast the breadcrumbs with garlic powder first for extra flavor, then sprinkle generously before baking. The final 2-3 minutes under the broiler is key—watch closely to avoid burning!
How do I prevent the mac and cheese from getting watery?
Always cook the pasta 1 minute less than package instructions and drain it well. Use sharp cheddar cheese (it melts better than pre-shredded) and avoid overmixing after adding eggs. If the mixture seems too loose, bake it 5 minutes longer covered with foil before broiling.
Can I use different types of cheese?
For extra richness, try Gruyère or Monterey Jack. For a smoky flavor, add ½ cup smoked gouda. If you want something sharper, pepper jack or white cheddar work well. Just use the same total amount (2 cups) for best results.
