16 Ounce Mac and Cheese Recipe: Extra-Creamy Bake With Crispy Breadcrumbs

A 16-ounce serving of mac and cheese should be extra-creamy, baked to golden perfection with crispy breadcrumbs on top—this is the recipe that finally delivers restaurant-quality results at home.

The secret lies in a proper cheese sauce made with sharp cheddar and Gruyère, cooked low and slow to prevent separation, while the breadcrumb topping adds irresistible texture. I’ve tested countless variations, and this method consistently produces mac and cheese with a velvety sauce that clings to every noodle.

This recipe balances tradition with modern techniques—using a roux for a stable sauce base and baking until the edges are bubbly and crispy. The 16-ounce portion serves one generously or two as a side, making it perfect for meal prep or a comforting weeknight dinner.

No shortcuts here: the cheese is melted thoroughly, the pasta is cooked al dente, and the breadcrumbs toast to a perfect golden brown.

What you’ll end up with is mac and cheese that’s rich, creamy, and crispy all at once—each bite delivers that perfect contrast of textures and flavors. The sauce is thick enough to coat every noodle but still silky smooth, while the breadcrumb topping adds a satisfying crunch.

This is the kind of mac and cheese that disappears faster than you can say “extra cheese.”

Ready to make it? We’ll start with the pasta, then build the sauce from scratch, and finish with the crispy topping. Every step is designed to ensure foolproof results—no lumps, no separation, just pure comfort food perfection.

Ingredients for 16 oz mac and cheese

Sixteen ounces of pure comfort—creamy, crispy, and impossible to resist.

The cheese is non-negotiable here. Sharp cheddar (the kind that makes your eyes water) and Gruyère (for that nutty depth) are the dynamic duo. Grab Kraft 2-year aged if you’re at the grocery store, or Wisconsin Sharp Cheddar from the deli section. For Gruyère, Whittard of Chelsea is worth the splurge, but the pre-shredded stuff from the cheese aisle works in a pinch. Pro tip: shred it yourself—pre-shredded gets clumpy and ruins the sauce texture. The milk and cream? Full-fat only—this is where the creaminess comes from, not shortcuts.

No sharp cheddar? Monterey Jack or Pepper Jack will work, but you’ll lose that tangy bite. Gruyère hard to find? Parmesan at half the amount adds saltiness but not the same nutty flavor. Panko breadcrumbs are a must for that crispy topping—Trader Joe’s or Costco have the best prices. Running low on butter? Olive oil in the roux works, but butter gives that unmistakable richness. The nutritional yeast is optional but adds a cheesy depth that makes this recipe next-level—Bob’s Red Mill is my go-to brand. And yes, you can use dried mustard if fresh isn’t available, but the flavor won’t be as bright.

Make the sauce ahead and refrigerate it—it actually tastes better the next day as the flavors meld. The breadcrumb topping? Toast it in the oven for 3-4 minutes before baking the mac and cheese to get maximum crispiness. Leftovers? 3-4 days in the fridge, but honestly, this disappears so fast you won’t have any. Freeze portions for up to 3 months—just microwave with a splash of milk to revive the creaminess. And for the love of mac and cheese, don’t skip the garlic. It’s the secret ingredient that ties everything together.

Step-by-step instructions for extra-creamy baked mac and cheese

Here’s how to make the richest, creamiest mac and cheese with a golden, crispy breadcrumb topping.

Bring a large pot of water to a rolling boil and add 1.5 teaspoons salt. Add the 4 oz elbow macaroni and cook until al dente—about 1 minute less than the package instructions suggest. You want the pasta to have a slight bite when you taste it.

Drain the pasta in a colander and return it to the pot. Give it a quick shake to break up any clumps, then set it aside. Don’t rinse the pasta—those starchy strands are what help create that ultra-creamy sauce later on. I like to keep the pot warm on the stove while I make the roux.

In a separate large skillet, melt the ½ cup unsalted butter over medium heat until it’s completely liquid but not browned. Add the ½ cup all-purpose flour all at once and whisk vigorously for 2-3 minutes until the mixture turns a light golden color and smells nutty.

This is your roux—the foundation of the sauce. You’ll know it’s ready when it coats the back of a spoon smoothly. Slowly whisk in the 1.5 cups whole milk and ½ cup heavy cream, letting each splash incorporate completely before adding more. The mixture will thicken into a smooth paste—this is your velvety base.

Reduce heat to low and gradually whisk in the 1.5 cups sharp cheddar cheese and ½ cup gruyère cheese until fully melted and smooth. Stir in the 1 tablespoon yellow mustard, 2 minced garlic cloves, 1.5 teaspoons salt, ½ teaspoon ground black pepper, and 1 tablespoon nutritional yeast for that umami depth.

Here’s where the magic happens: the sauce should be thick enough to coat the back of a spoon but still silky. If it’s too thick, whisk in 1-2 tablespoons of pasta water until it reaches a perfect coating consistency. The nutritional yeast adds a subtle cheesy flavor that takes this dish to the next level.

Add the cooked elbow macaroni to the cheese sauce and stir gently to coat every strand completely. The pasta will absorb some of the sauce, so don’t worry if it looks slightly dry at first—it’ll come together as it bakes. Transfer the mixture to a greased 8×8-inch baking dish and spread it evenly.

This is the moment where all your hard work pays off. The sauce should be glossy and cling beautifully to the pasta. If you see any dry spots, stir in a splash of warm milk to ensure everything is perfectly coated before baking.

In a small bowl, mix the ½ cup panko breadcrumbs with 1 tablespoon extra-virgin olive oil until evenly coated. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently to help it stick.

Bake at 375°F for 15-18 minutes until the top is deep golden brown and the edges are bubbling. The breadcrumbs should be crispy while the cheese underneath remains perfectly creamy. If you’re worried about it browning too quickly, tent the dish with foil for the last 5 minutes of baking.

Remove from the oven and let the mac and cheese rest for 5 minutes before serving. This resting time allows the cheese to set slightly, making it easier to slice and ensuring that first bite is perfectly creamy.

Serve immediately with a side of steamed vegetables or a simple green salad. The contrast between the crispy breadcrumb topping and the ultra-creamy cheese sauce makes this mac and cheese truly unforgettable. The sharp cheddar and nutty gruyère combination creates a flavor profile that’s both comforting and sophisticated.

Dietary considerations for these flavors

Gluten-Free Adaptation

For a gluten-free version, swap the elbow macaroni for gluten-free pasta like Barilla GF Penne or De Cecco GF Fusilli. Cook it al dente as directed, but add 1 extra minute to ensure it’s fully tender.

The roux can be made with gluten-free all-purpose flour like Bob’s Red Mill 1:1, though the texture will be slightly lighter. To compensate, whisk in 1 extra tablespoon of cornstarch with the flour for a thicker, creamier sauce. 🥗

Dairy-Free Options

Skip the butter and cheese entirely and use olive oil for the roux. Replace the cheddar and Gruyère with dairy-free cheeses like Miyoko’s Sharp Cheddar or Violife Smoked Gouda, both of which melt beautifully.

For creaminess, substitute the milk and heavy cream with full-fat coconut milk—it adds richness without dairy. Add 1 teaspoon nutritional yeast to boost umami flavor, as dairy-free cheeses often lack depth. 🌱

Lower-Carb Keto

Transform this into a keto-friendly dish by replacing the pasta with shredded cauliflower or zucchini noodles. Sauté 2 cups cauliflower florets in 1 tbsp butter until tender, then drain well.

Use the same cheese sauce recipe, but reduce the heavy cream to ¼ cup and add 2 tbsp cream cheese for extra creaminess. Top with crushed pork rinds instead of panko for a crispy, gluten-free, low-carb crust. 🥬

Lactose-Free Adjustments

Lactose-free mac and cheese is easier than you think! Use lactose-free butter (like Land O’Lakes Lactose-Free) for the roux, and replace the milk and cream with lactose-free versions (such as Fairlife Lactose-Free).

For the cheese, opt for lactose-free cheddar like Kraft Lactose-Free or Wisconsin Lactose-Free Sharp Cheddar. The sauce will still be creamy and flavorful, with no digestive discomfort. 🧀

Vegetarian Protein Boost

Add plant-based protein by mixing in ½ cup cooked lentils or crumbled tempeh into the cheese sauce. For lentils, simmer ¼ cup dried green lentils in the pasta water until tender, then drain and stir into the sauce.

For tempeh, pan-fry ½ cup crumbled tempeh until crispy, then sprinkle on top before baking. Both options add heartiness without altering the creamy texture. 🌿

Allergen-Friendly Tips

For nut allergies, avoid Gruyère (some brands process in nut facilities) and use Parmesan instead. For soy allergies, check your cheese labels—some brands use soy-based anti-caking agents. Always double-check breadcrumbs for hidden allergens; Trader Joe’s gluten-free breadcrumbs are a safe option.

When in doubt, make your own topping with crushed gluten-free crackers or toasted seeds like sunflower or pumpkin. 🚫
