Ingredients for Mac and Cheese Recipe with Eggs and Milk

Pantry staples come together for this creamy, custard-style baked delight.

The cheese is everything here. Cabot or Tillamook sharp cheddar melts beautifully and has that perfect tang. Most supermarkets carry it in blocks—avoid pre-shredded (it has anti-caking agents that mess with the melt). The macaroni should be elbow or cavatappi for maximum sauce cling. I grab mine at Whole Foods when they have sales, but any brand works as long as it’s al dente after boiling.

No sharp cheddar? Gruyère or Monterey Jack work great too (or half and half for complexity). Swap whole milk for 2% in a pinch, but don’t go lower—fat matters here. Out of Dijon? Regular yellow mustard at half the amount does the trick. The Worcestershire is optional but adds depth; Annie’s makes a vegetarian version that’s easy to find.

This bakes up even better the next day. Leftovers keep in the fridge for 4 days—reheat covered with foil to prevent drying. Freeze portions for up to 3 months (thaw overnight before reheating). The breadcrumb topping? Add it fresh for maximum crunch.

Step-by-Step Instructions for Baked Custard-Style Mac and Cheese

Here’s the method I use—simple, tested, and delivers that creamy, comforting texture every time.

Step 1: Cook the Elbow Macaroni Al Dente

Bring a large pot of salted water to a boil. Add the 8 oz Elbow Macaroni and cook for 1 minute less than the package directions. You want it slightly underdone because it’ll finish cooking in the oven. Drain well in a colander and set aside.

I always rinse my pasta with cool water after draining to stop the cooking process completely. This prevents it from turning mushy when baked with the custard. Shake the colander gently to remove excess water—you don’t want a watery sauce.

Step 2: Create the Cheddar-Gruyère Béchamel Base

In a saucepan over medium heat, melt the 3 tbsp Unsalted Butter. Once foaming subsides, whisk in the 3 tbsp All-Purpose Flour to form a roux. Cook for 1-2 minutes until the mixture turns a light golden color and smells nutty.

Gradually whisk in the 2 cups Whole Milk, 1 tsp Dijon Mustard, 1 tsp Worcestershire Sauce, 1 tsp Kosher Salt, 0.5 tsp Freshly Ground Black Pepper, and 0.25 tsp Ground Nutmeg. Continue whisking until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes.

Reduce heat to low and stir in the 2 cups Sharp Cheddar Cheese and 1 cup Gruyère Cheese until fully melted and smooth. The sauce should be thick but pourable. Remove from heat and let cool slightly.

Step 3: Combine Pasta with Egg Custard Mixture

In a large bowl, beat the 2 whole Large Eggs lightly. Slowly whisk about 1 cup of the warm cheese sauce into the eggs to temper them—this prevents the eggs from scrambling when combined with the hot sauce.

Pour the egg mixture back into the remaining cheese sauce, whisking constantly. Add the cooked elbow macaroni and stir until every piece is thoroughly coated. The mixture will look thick and creamy, almost like a batter.

Step 4: Top with Panko and Bake to Golden Perfection

Transfer the macaroni mixture to a greased 9×13-inch baking dish or similar. Sprinkle the 0.5 cup Panko Breadcrumbs evenly over the top. For extra crunch, I like to melt a little extra butter and drizzle it over the breadcrumbs.

Bake in a preheated 375°F oven for 25-30 minutes until the top is golden brown and the edges are bubbling. Let it rest for 5 minutes before serving—the custard needs this time to set properly. The center should be creamy but not runny, with a beautiful golden crust on top.

Common Mistakes When Making This Recipe

Overcooking the Pasta

Cook your elbow macaroni for 1 minute less than the package says. I learned this the hard way in my tiny Boston kitchen—mushy noodles ruin the texture. They’ll finish perfectly in the oven. 💡

Skipping the Tempering Step

Always temper your eggs by slowly whisking in 1 cup of the warm cheese sauce first. Pouring hot sauce directly into eggs causes scrambling. I’ve tested this multiple times—tempering is non-negotiable.

Using Pre-Shredded Cheese

Pre-shredded cheese has anti-caking agents that prevent smooth melting. Stick with Cabot or Tillamook sharp cheddar blocks and shred it yourself. The difference in creaminess is noticeable.

Under-seasoning the Sauce

Don’t skip the 1 tsp salt, 0.5 tsp black pepper, and 1 tsp Dijon mustard. These seasonings elevate the flavor beyond just cheesy. I taste as I go and adjust if needed.

Skipping the Rest Time

Let your mac and cheese rest for 5 minutes after baking. This allows the custard to set properly. Cutting too soon results in a runny center. 🔥

Overfilling the Dish

Use a 9×13-inch baking dish and don’t overfill it. The custard needs room to expand as it bakes. I grease mine lightly with butter to prevent sticking.
