Ingredients for baked mac and cheese with ground beef

Pantry staples plus a few key ingredients for that perfect cheesy, meaty one-pan dinner.

The ground beef is where the magic happens—80/20 fat ratio gives you that juicy, flavorful bite. Trader Joe's or Costco usually have the best prices for bulk packs, and you can freeze extras for future meals. Look for bright red color and good marbling when buying. The macaroni? Medium or jumbo elbow stays tender longer than small shapes. I always cook it al dente—it finishes perfectly in the oven. For the cheeses, block cheddar shreds better than pre-shredded (no anti-caking agents), and Parmigiano-Reggiano for the Parmesan adds depth that powdered can't match.

No 80/20 ground beef? 85/15 works but stays drier—just add an extra tablespoon of butter to compensate. Short on Monterey Jack? Extra sharp cheddar gives a similar tang. The beef broth can be swapped for chicken broth in a pinch, but the mustard powder is non-negotiable—it's what gives this sauce that subtle, restaurant-quality depth. For the roux, don't rush the cooking—you want it golden brown, not burnt. And if you're out of panko, regular breadcrumbs toasted in butter work just fine. Fresh garlic is ideal, but garlic powder at half the amount gets you close if you're in a hurry.

This reheats like a dream—best the next day when all the flavors meld. Store leftovers covered in the fridge for up to 5 days, or freeze portions for 3 months. For meal prep, I portion it into individual containers so I can grab and heat just what I need. The breadcrumb topping stays crispy for about 2 days if stored properly, so if you're not baking it right away, skip the topping and add it fresh before serving. The cheese sauce thickens as it cools, so if it looks too thick when reheating, just stir in a splash of milk.

Step-by-step instructions for baked mac and cheese with ground beef

Here's how to make this hearty, one-pan wonder with perfect texture and rich flavor.

Heat a large oven-safe skillet over medium-high heat and add the 1 lb ground beef (80/20). Break it up with a wooden spoon as it cooks, letting the fat render out. You want it to brown nicely—about 5-6 minutes—but not burn. Once browned, transfer the beef to a plate and set aside.

In the same skillet, add ½ cup unsalted butter and let it melt completely. Toss in the 1 whole yellow onion and 4 cloves minced garlic, cooking until the onion is translucent and the garlic is fragrant—about 3-4 minutes. Here's the thing—don't walk away. Garlic burns fast, and you want that sweet, nutty aroma.

Reduce heat to medium and sprinkle in the ½ cup all-purpose flour, whisking constantly for 1-2 minutes until it forms a smooth, pale roux. This is your sauce foundation—don't rush it or you'll get a gritty texture. Slow and steady wins the race.

Gradually pour in the 2 cups whole milk while whisking vigorously to prevent lumps. Let the mixture simmer for 3-4 minutes until it thickens enough to coat the back of a spoon. Now's the time to add the 1.5 tsp kosher salt, ½ tsp ground black pepper, and ½ tsp dried mustard powder, stirring well to combine. This subtle mustard powder adds depth that takes this dish to next-level delicious.

Bring a large pot of salted water to a boil and cook the 12 oz elbow macaroni until al dente—about 1 minute less than package instructions. Drain well and add it directly to the skillet with the cheese sauce. Stir everything together, then reduce heat to low and add the 2 cups sharp cheddar cheese, 1 cup monterey jack cheese, and ½ cup freshly grated parmesan cheese.

Stir constantly until all the cheese melts completely—about 2-3 minutes. You'll see the sauce transform into a luscious, velvety blanket coating every strand of pasta. If it looks too thick, add ¼ cup beef broth to loosen it up. The goal is a sauce that clings beautifully without being gluey.

Preheat your oven to 375°F. Transfer the mac and cheese mixture to a 9x13-inch baking dish (or your oven-safe skillet if large enough). Sprinkle the ¼ cup panko breadcrumbs evenly over the top, pressing down gently to help them adhere. Here's where the magic happens—those breadcrumbs will create a crispy, crunchy topping while the cheese below stays creamy.

Bake uncovered for 20-25 minutes until the top is deep golden brown and bubbly. The edges should be slightly crispy, and the cheese should be melted through. If you're unsure, check at the 20-minute mark—every oven runs hot or cold. The moment it looks perfect is when you pull it out. Let it rest for 5 minutes before serving to let the top set slightly.

Slice into squares and serve immediately. Each bite should deliver tender pasta, rich cheese sauce, and savory beef throughout. The crispy breadcrumb topping adds the perfect textural contrast. For extra decadence, drizzle with a little extra beef broth or serve with a side of steamed green beans to balance the richness.

This dish tastes even better the next day, so don't be surprised if you find yourself sneaking seconds—or thirds. The flavors meld beautifully overnight, making it perfect for meal prep too. Just reheat gently in the oven or microwave until warmed through.

Up North, they love their cheese extra crispy! After baking, sprinkle ¼ cup crushed Ritz crackers mixed with 2 tbsp melted butter on top, then broil for 2-3 minutes until golden. Add ½ cup diced ham to the beef mixture for a salty-sweet contrast.

The cracker topping gives that signature New England crunch while keeping the inside gooey. Perfect for cold winter nights!
