What is Ultimate Baked Mac and Cheese?

So, what makes Ultimate Baked Mac and Cheese the ultimate? It’s all about balance. We’re talking a creamy, rich cheese sauce that clings to every noodle, topped with a melty, slightly crispy cheese crust that’s straight-up drool-worthy. Unlike the stovetop versions that are all sauce and no structure, this baked version holds its shape beautifully while still staying luscious inside. It’s made with a classic roux-based cheese sauce (don’t worry, we’ll keep it simple), and a combo of cheddar and Monterey Jack for that dreamy melt and flavor blend.

A few little additions—like a pinch of nutmeg and ground mustard—give it a low-key gourmet twist. Serve it on its own or make it the star of your holiday table, this mac and cheese is reliable, foolproof, and always a crowd-pleaser.

Reasons to Try Ultimate Baked Mac and Cheese

Let’s be honest—boxed mac and cheese is fine in a pinch, but once you taste the real deal, there’s no going back. The Ultimate Baked Mac and Cheese is worth it because it gives you that creamy, soul-hugging experience without being overly complicated or time-consuming. It’s weeknight-worthy and holiday-ready. You’ll love how the cheese sauce turns out velvety smooth—no gritty weirdness, no separation—thanks to a few tried-and-true techniques.

Plus, this recipe doesn’t mess around with dry noodles or bland bites. We undercook the pasta slightly and cover it during the first part of baking so it soaks up just the right amount of sauce. Your family, friends, even picky eaters will go in for seconds—maybe thirds. Need another reason? It reheats like a dream. Still not convinced? Pair it with something cozy like this Crock Pot Cheddar Chili Mac and you’re basically winning dinner.

• 1 teaspoon salt

Instructions to Make Ultimate Baked Mac and Cheese

Ready to make the Ultimate Baked Mac and Cheese? This step by step guide walks you through each part of the process so your dish comes out ultra-creamy, never dry, and full of cheesy flavor. No culinary degree required—just a little butter, a big appetite, and a baking dish that’s ready for greatness.

Step 1: Preheat Your Oven and Prepare the Dish

Start this step by setting your oven to 375°F (190°C). While it heats up, lightly grease a 9×13-inch baking dish with a bit of butter or cooking spray. This keeps your mac and cheese from sticking to the sides and makes cleanup easier. If you’re planning a hearty meal night, this casserole pairs perfectly with our Crockpot Cowboy Casserole as a sidekick.

Step 2: Boil the Macaroni Slightly Under Al Dente

In a large pot, bring salted water to a boil and add 1 pound of elbow macaroni. Here’s the key step: cook the pasta for 2 minutes less than what the package recommends for al dente. Why? Because it will finish cooking in the oven and soak up that dreamy cheese sauce without turning into mush. Drain it well and set it aside while you work on the sauce.

Step 3: Make a Smooth Roux Base

In a large saucepan or Dutch oven, melt ½ cup of unsalted butter over medium heat. Once melted, sprinkle in ½ cup of all-purpose flour while whisking constantly. This step creates a roux—a simple but magical combo that thickens your cheese sauce and prevents it from separating later. Cook for about 1–2 minutes until it’s smooth and lightly golden (not browned). Keep whisking! It should smell slightly nutty.

Step 4: Slowly Add the Milk

Once the roux is ready, slowly whisk in 4 cups of whole milk, a little at a time. Don’t dump it in all at once—this step by step addition helps prevent lumps and gives you better control over the sauce’s thickness. Continue whisking for 5–7 minutes until the mixture thickens enough to coat the back of a spoon. This is your foundation for a luxuriously creamy cheese sauce.

Step 5: Season and Add the Cheese

Turn off the heat and stir in your seasoning:

• 1 teaspoon salt
• ½ teaspoon black pepper
• ¼ teaspoon ground mustard (optional, but adds a subtle tang)
• ¼ teaspoon nutmeg (optional, adds warmth and depth)

Next, stir in 3 cups of shredded cheddar cheese and 1 cup of Monterey Jack. Use the residual heat from the sauce to melt the cheese slowly—don’t rush it. Stir gently until it’s fully melted and silky smooth. This step is what makes Ultimate Baked Mac and Cheese shine.

Step 6: Combine Pasta and Cheese Sauce

Gently fold your slightly undercooked macaroni into the cheese sauce. Stir until each noodle is coated in that golden goodness. It should look thick and luscious, not watery. This step by step layering of flavor ensures every bite delivers.

Step 7: Assemble in the Baking Dish

Pour the macaroni and cheese mixture into your prepared baking dish. Then, sprinkle the remaining 1 cup cheddar and 1 cup Monterey Jack over the top. Don’t skip this—it creates that irresistible cheesy crust that turns golden and bubbly in the oven. If you’re feeling bold, you can also toss on some seasoned breadcrumbs for extra crunch, like we do in our Easy Hobo Casserole.

Step 8: Cover and Bake

Cover the baking dish tightly with foil and bake for 20 minutes. This traps steam and keeps your mac from drying out—a must-follow step in this step by step method.

Step 9: Uncover and Brown the Top

Remove the foil and bake for another 10–15 minutes, or until the top is golden and bubbly. This finishing step gives your dish that show-stopping look and texture. If you’re planning a meal for guests, serve this alongside our Chicken Pot Pie Casserole for the ultimate comfort duo.

Step 10: Let It Rest, Then Serve

Once baked, let your mac and cheese rest for 5–10 minutes before digging in. This final step helps the sauce set just enough to serve clean slices while keeping that creamy, gooey magic. Trust us—it’s worth the wait.

What to Serve with Ultimate Baked Mac and Cheese

This dish is basically a meal on its own, but if you’re looking to round it out, go for something that contrasts the richness. A crisp green salad with vinaigrette is always a solid move. Roasted veggies like Brussels sprouts or broccoli balance out the decadence. Want to stick with comfort food? Try it next to Chicken Pot Pie Casserole or Crockpot Cowboy Casserole for the ultimate cozy night in. If you’re making it for the holidays, it fits in perfectly with ham, turkey, or even just a slab of crusty garlic bread. Bonus points if you throw in something sweet like this Texas Chocolate Pecan Pie for dessert.

Key Tips for Making Ultimate Baked Mac and Cheese

1. Undercook the pasta just a smidge—about 2 minutes less than al dente—so it doesn’t get mushy while baking.
2. Don’t skip the roux. It’s what keeps your cheese sauce stable and creamy without curdling or separating.
3. Use fresh cheese, not pre-shredded if you can. Pre-shredded has anti-caking agents that can mess with the texture.
4. Cover it while baking—at least at first. This keeps it from drying out.
5. Rest before serving. Those few minutes after baking help everything settle and make it easier to scoop.
6. Want a little texture? Throw some seasoned breadcrumbs on top for the last 10 minutes. Optional, but yum.

Storage and Reheating Tips for Ultimate Baked Mac and Cheese

Leftovers? Lucky you. Store any extra in an airtight container in the fridge for up to 4 days. When reheating, the trick is keeping it creamy. The microwave works, but add a splash of milk before zapping it, then stir halfway through. If you’ve got more time, reheat it in the oven at 325°F, covered with foil. Again—add a little milk first. Want to freeze it? Totally doable. Freeze in portions for up to 2 months. Thaw overnight in the fridge, then reheat as above. Pro tip: If you plan to freeze it, slightly underbake so it doesn’t get dry when you reheat.

FAQs

Can I make this ahead of time?
Yes! Assemble it fully (without baking), cover, and refrigerate for up to 24 hours. Bake as directed, adding 5–10 extra minutes.

Can I use different cheeses?
Of course. Gruyère, fontina, gouda, or even a sharp provolone work great. Just pick ones that melt well.

Is it okay to skip the nutmeg or mustard?
Totally. But if you’re curious, those tiny amounts actually enhance the cheese flavor. Worth a try!

Can I make it gluten-free?
Yes—use GF pasta and a 1:1 gluten-free flour blend for the roux.

How do I stop the sauce from turning grainy?
Melt cheese off the heat and whisk slowly. Avoid pre-shredded cheese if possible.
