Ingredients for baked mac and cheese recipe with egg and milk
Twelve essential ingredients transform ordinary mac and cheese into a breakfast casserole masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lb | Medium or short cut preferred |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, block preferred |
| Extra-Sharp White Cheddar Cheese 🧀 | 1 cup | For deeper flavor punch |
| Large Eggs 🥚 | 4 whole | Room temperature for best binding |
| Whole Milk 🥛 | 1 ½ cups | Full-fat for richest texture |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for even melting |
| All-Purpose Flour 🌾 | ¼ cup | For silky sauce consistency |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste, don't skip |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for brightness |
| Panko Breadcrumbs 🍞 | ½ cup | For extra-crispy topping |
| Garlic Powder 🧄 | ½ tsp | Enhances cheesy depth |
| Mustard Powder 🌶️ | ¼ tsp | Brightens flavor profile |
| Nutritional Yeast 🍃 | 1 tbsp | Optional umami boost |
The cheeses are non-negotiable. Sharp cheddar gives that classic tang, but extra-sharp white cheddar takes it to restaurant-level depth. I always grab the block and shred it myself—pre-shredded gets clumpy and lacks that fresh-from-the-grater texture. For the milk, whole milk is a must—it creates that velvety, luxurious sauce that separates this from basic recipes. The eggs? Room temperature is key—they bind everything together without curdling. Freshly ground black pepper makes all the difference too—pre-ground tastes flat in comparison. Stock up on these staples at Whole Foods or your local specialty grocer for the best quality.
No sharp cheddar? Extra-sharp white cheddar mixed with a little pepper jack works beautifully. Running low on whole milk? Half-and-half gives similar richness, though it'll be slightly lighter. The butter should be cold and cubed—melting it first ruins the sauce's silky texture. For the breadcrumbs, Panko is a must for that perfect crunch, but if you've got Italian breadcrumbs, they'll work too. The garlic powder and mustard powder might seem minor, but they're what elevate this from basic to extraordinary. Penzeys spices are my go-to for these—bright, flavorful, and consistent. Nutritional yeast is optional but adds that savory depth that makes this taste like it came from a high-end brunch spot.
This reheats like a dream—honestly better the next day as flavors meld. Keeps 4-5 days in the fridge, fully wrapped to prevent drying. For make-ahead prep, assemble the casserole a day ahead and refrigerate—just add the breadcrumb topping before baking. Freezes beautifully for up to 3 months if you want to prep for holidays or busy weeks. I always portion mine into individual servings before freezing so I can grab and reheat exactly what I need. The leftovers? Microwave with a splash of milk to restore that creamy texture—game changer.

- Cheese Overload (In a Good Way): Sharp cheddar and extra-sharp white cheddar? That’s not just flavor—it’s a texture party. The sharpness cuts through the richness, and the eggs bind it all into that perfect creamy, slightly crispy bite. (Yes, even my cheese-averse roommate licks the plate.)
- Weeknight to Potluck Hero: Make it for Tuesday dinners or bring it to a picnic—this holds up everywhere. The egg-milk mix keeps it sturdy, and the baked edge? It’s the kind of dish that gets passed around at gatherings because no one wants to stop eating it.
- Budget-Friendly Leftovers: A single batch feeds four, and the leftovers? Even better. The cheese gets deeper in flavor overnight, and reheating it just adds to that melty, comforting magic. Plus, elbow mac and whole milk won’t break the bank—unlike those gourmet recipes that cost more than the groceries.
Step-by-step instructions for baked mac and cheese with egg and milk
This isn't your grandma's mac and cheese—we're making a breakfast-worthy casserole with crispy tops and silky centers.
Cook the Elbow Macaroni to Perfect Al Dente
Bring a large pot of water to a rolling boil and add the 1.5 lb elbow macaroni. I use a 12-quart stockpot because elbow macaroni expands significantly. Cook until 1 minute before the package directions specify for al dente—this ensures it finishes cooking in the oven without becoming mushy.
Drain the pasta in a colander, but don't rinse it. The starch clinging to the noodles is what helps create that silky sauce later. While it's draining, I like to give it a good shake in the colander to break up any clumps—this prevents a gummy final texture. Transfer the drained macaroni to a large mixing bowl and set it aside.
Create the Silky Cheese Sauce Foundation
In a separate large bowl, whisk together the 1.5 cups sharp cheddar cheese, 1 cup extra-sharp white cheddar cheese, 4 whole large eggs, 1.5 cups whole milk, and 1 tbsp nutritional yeast. The nutritional yeast adds that savory umami depth that makes this dish truly special. Use a whisk or electric mixer on medium speed to combine everything until smooth and fully emulsified.
This is where the magic happens—the combination of sharp and white cheddar creates layers of flavor, while the eggs and milk create that signature creamy texture. If you see any lumps of cheese, don't worry—we'll melt them out in the next step. The mixture should be thick but pourable at this stage.
Build the Ultimate Cheesy Mixture
Add the cooked macaroni to the cheese mixture and gently fold everything together using a rubber spatula. You want to distribute the cheese sauce evenly throughout the noodles without breaking them up too much. Then, in a small bowl, combine the 0.5 cup unsalted butter, 0.25 cup all-purpose flour, 1.5 tsp diamond crystal kosher salt, 0.5 tsp freshly ground black pepper, 0.5 tsp garlic powder, and 0.25 tsp mustard powder. The mustard powder might seem odd, but it brightens the rich cheese flavors beautifully.
Melt the butter-flour mixture in a small saucepan over medium heat, stirring constantly until it forms a smooth, thick paste. This is your roux, and it's what gives the final dish that velvety texture. Pour this hot mixture into the macaroni-cheese bowl and fold everything together until completely combined. The heat from the roux will help melt any remaining cheese lumps.
Assemble and Bake to Crispy Perfection
Transfer the macaroni-cheese mixture to a 9x13-inch baking dish, spreading it out evenly. The dish should be about ¾ full—this gives the casserole room to rise slightly in the oven. Sprinkle the 0.5 cup panko breadcrumbs evenly over the top. The panko will create that coveted crispy crust while adding a subtle toasty flavor.
Bake at 375°F for 25-30 minutes until the top is deep golden brown and the edges are bubbling. Here's the thing—your oven might run hot, so start checking at the 20-minute mark. The casserole is done when the center is still slightly jiggly (it'll firm up as it cools) and the top has that beautiful crispy crust. If it browns too quickly, tent it loosely with aluminum foil.
Rest and Serve with Confidence
Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This resting period is crucial—it allows the cheese to set slightly and the flavors to meld together. The internal temperature should reach 160°F by the time you serve it, ensuring it's safe to eat while maintaining that perfect creamy texture.
Cut into squares and serve immediately. Each bite should deliver that perfect contrast of crispy panko on top and silky, cheesy macaroni underneath. This isn't just mac and cheese—it's a breakfast casserole that's perfect for brunch, a hearty lunch, or even a comforting dinner. The combination of sharp and white cheddar with the umami boost from nutritional yeast makes this dish truly extraordinary.
Pro Tips For Making Baked Mac And Cheese Recipe With Egg And Milk
- Boil Pasta Until Al Dente: Elbow macaroni should still have a tiny bite when it hits the cheese sauce—overcooking turns it mushy, and that’s a crime. Drain it just before it’s fully done, then finish cooking in the oven; it’ll absorb the sauce perfectly without falling apart.
- Grate Cheese Like a Pro: Skip the food processor—it turns cheese into paste. Use a box grater for sharp cheddar and a microplane for extra-sharp white cheddar (it melts smoother and adds that perfect tang). Mix them together in the sauce for layers of flavor.
- Temper the Eggs First: Cold eggs in hot milk? Nope. Whisk them with a splash of warm milk first, then slowly mix into the rest—this keeps the sauce creamy, not scrambled. I learned this the hard way when my first batch looked like a cheese omelet.
- Bake Covered, Then Uncover: Start with foil on tight to melt the cheese evenly, then remove it for the last 5–7 minutes. This gives you a golden top without drying out the edges. (Yes, even if you’re impatient like me—resist peeking!)
Make-ahead tips for this dish
Day-Ahead Prep
Assemble the entire casserole the night before and refrigerate it uncovered—this allows the cheese to firm up slightly, making it easier to slice later. Just before baking, sprinkle the panko breadcrumbs on top and bake as directed.
The flavors actually deepen overnight, giving you an even more complex dish in the morning. 💫
Freezer-Friendly
This mac and cheese freezes beautifully for up to 3 months—perfect for meal prep or holiday gatherings. After assembling but before adding the breadcrumb topping, wrap the baking dish tightly in plastic wrap followed by aluminum foil.
When ready to bake, thaw overnight in the fridge, add the panko topping, and bake as usual. The texture remains creamy and delicious.
Portion Control
For easy reheating, divide the baked casserole into individual 8x8-inch portions before freezing. Store each portion in a separate airtight container with parchment paper between layers to prevent sticking. This way, you can grab exactly what you need without thawing the whole dish.
Just reheat covered in the microwave for 2-3 minutes or in the oven at 350°F for 15 minutes.
Make-Ahead Topping
Pre-mix the breadcrumb topping ingredients—panko, garlic powder, and mustard powder—in a small bowl and store it in an airtight container for up to 1 week.
This saves time on baking day and ensures your topping stays fresh. Sprinkle it on just before baking to maintain that perfect crispy texture. ⏰
Reheating Leftovers
Leftovers reheat best in the oven for that creamy texture. Cover with aluminum foil and warm at 350°F for 10-15 minutes. For microwave reheating, add 1-2 tablespoons of milk or water to restore creaminess—this prevents drying out.
Stir halfway through for even heating. The dish stays delicious for 4-5 days in the fridge.
Holiday Prep
Double the recipe and bake in two 9x13-inch dishes for parties or potlucks. Wrap each dish individually in foil and store in a cool dark place for up to 2 days before serving.
Reheat covered at 325°F for 20 minutes to maintain moisture. This makes an impressive dish that's easy to transport and serve family-style. 💡

Frequently asked questions
Why does this recipe use both eggs and milk?
The eggs and milk work together to create that signature creamy, velvety texture while helping the cheese sauce bind perfectly to the macaroni. The eggs provide structure and richness, while the milk adds smoothness and prevents the dish from becoming too dense. This combination also helps create that coveted crispy crust when baked.
Can I make this dish without panko breadcrumbs?
Yes, but you'll lose that perfect crispy texture. For a similar effect, try crushed cornflakes or toasted breadcrumbs. If you prefer a smoother top, simply omit the breadcrumbs or use a sprinkle of extra cheese. Just know the crust will be softer without them.
How do I prevent the mac and cheese from getting watery?
Never rinse the cooked pasta—those starches are essential for binding the sauce. Also, make sure your baking dish isn't too large (use a 9x13-inch pan). If it looks too wet before baking, let it sit at room temperature for 10 minutes to thicken slightly. The eggs and roux in this recipe help prevent wateriness too.
What's the best way to reheat leftovers?
For creamy perfection, cover with foil and reheat at 350°F for 10-15 minutes. If using a microwave, add 1-2 tablespoons of milk and stir halfway through. Never microwave without liquid—it'll dry out completely. The oven method gives you that restaurant-style texture every time.
Can I add other ingredients like bacon or veggies?
Cook ½ lb bacon until crispy and crumble it into the macaroni, or stir in 1 cup steamed broccoli for extra nutrition. Just
