Hey there! Let me tell you about my absolute favorite weeknight dinner. When I’m tired, when the weather turns chilly, when I just need something that feels like a warm hug in a dish—I turn to my cheesy beef and macaroni casserole. I’ve been making this for years, tweaking it here and there until it became the perfect cozy meal my whole family begs for.

I remember the first time I threw it together. It was one of those nights where I had ground beef in the fridge, some pasta in the pantry, and not much else. I thought, “What if I just combine everything I love about mac and cheese with everything I love about a good beef casserole?” And oh my goodness, the result was magic. The smell that fills your kitchen as it bakes—that rich, cheesy, beefy aroma—is pure comfort. It’s the kind of meal that makes everyone gather around the table without being called twice.

What I love most about this cheesy beef and macaroni casserole is how forgiving it is. Don’t have exactly the right cheese? Use what you’ve got. Want to sneak in some veggies? Go for it.

Here are my top reasons this cheesy beef and macaroni casserole deserves a spot in your regular rotation:

Ingredients for the Ultimate Cheesy Beef and Macaroni Casserole

Here’s what you’ll need to make this comforting dish. Don’t worry if you don’t have exactly these ingredients—I’ll share some swaps in the variations section!

Main Ingredients

• 1 pound ground beef (I use 85% lean for the best flavor)
• 8 ounces elbow macaroni (about 2 cups dry)
• 2 cups shredded cheddar cheese (divided—save ½ cup for the topping)
• 1 cup shredded mozzarella cheese
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 can (15 ounces) tomato sauce
• 1 cup beef broth
• ½ cup milk (whole or 2% works best)
• 2 tablespoons all-purpose flour
• 2 tablespoons butter

Seasonings

• 1 teaspoon salt (plus more for pasta water)
• ½ teaspoon black pepper
• 1 teaspoon dried oregano
• ½ teaspoon paprika (smoked paprika is amazing if you have it)
• ½ teaspoon garlic powder

A quick note about the cheese: I love the combination of cheddar for sharpness and mozzarella for that wonderful stretch, but you can use any melting cheese you like. Colby Jack, Monterey Jack, or even pepper jack for a little kick would all work beautifully in this cheesy beef and macaroni casserole.

How to Make Your Cheesy Beef and Macaroni Casserole

Ready to get cooking? Let’s walk through this step-by-step. I promise it’s easier than it looks!

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to package directions, but subtract 1-2 minutes from the suggested time. We want it al dente since it will continue cooking in the oven. Drain and set aside.

Step 2: Brown the Beef

While the pasta cooks, heat a large skillet or Dutch oven over medium-high heat. Add the ground beef and break it up with a wooden spoon. Cook until browned, about 5-7 minutes. Use a slotted spoon to transfer the beef to a bowl, leaving about 1 tablespoon of fat in the pan.

Step 3: Build the Sauce

Add the butter to the same pan with the beef fat. Once melted, add the chopped onion and cook until softened, about 3-4 minutes. Add the garlic and cook for another 30 seconds until fragrant. Sprinkle in the flour and stir constantly for about 1 minute—this helps thicken our sauce later.

Slowly pour in the beef broth while stirring to prevent lumps. Then add the milk, tomato sauce, and all seasonings. Bring to a simmer and cook for 3-4 minutes until slightly thickened.

Step 4: Combine Everything

Preheat your oven to 375°F (190°C). Return the cooked beef to the sauce, then stir in the cooked pasta and 1½ cups of the shredded cheddar cheese (reserve the remaining ½ cup for topping) along with all the mozzarella. Stir until everything is beautifully coated and the cheese starts to melt.

Step 5: Bake to Perfection

Transfer the mixture to a 9×13 inch baking dish. Sprinkle the remaining ½ cup cheddar cheese evenly over the top. Bake for 20-25 minutes until bubbly around the edges and golden on top. Let it rest for 5-10 minutes before serving—this helps it set up perfectly.

My pro tip: If you want an extra crispy top, broil for the last 1-2 minutes, but watch it carefully! No one wants burned cheese on their cheesy beef and macaroni casserole.

Delicious Variations for Your Casserole

One of the best things about this recipe is how adaptable it is. Here are some of my favorite twists on the classic cheesy beef and macaroni casserole:

Veggie-Packed Version

Add 1 cup of finely chopped vegetables when you cook the onions. Bell peppers, mushrooms, zucchini, or spinach all work beautifully. If using spinach, stir it in at the very end before baking—it wilts perfectly in the residual heat.

Spicy Kick

Add 1 diced jalapeño (seeds removed if you want less heat) with the onions, or stir in 1 teaspoon of chili powder with the other seasonings. You could also use pepper jack cheese instead of mozzarella for extra spice.

Italian-Inspired

Swap the oregano for Italian seasoning, use Italian sausage instead of ground beef, and add a tablespoon of tomato paste to the sauce. Top with Parmesan cheese instead of extra cheddar before baking.

Lower-Carb Option

Use cauliflower florets instead of pasta! Just steam or roast them until tender-crisp before adding to the sauce. The texture will be different but still delicious.

Remember, cooking should be fun and creative. Don’t be afraid to make this cheesy beef and macaroni casserole your own. Some of my best recipe discoveries have come from “what if I try this?” moments in the kitchen.

Serving and Storing Your Cheesy Beef and Macaroni Casserole

Now for the best part—enjoying your creation! Here’s how to serve and store your cheesy beef and macaroni casserole for maximum deliciousness.

Serving Suggestions

This dish is hearty enough to stand on its own, but I love serving it with:

• A simple green salad with vinaigrette dressing (the acidity cuts through the richness)
• Garlic bread or dinner rolls for soaking up every last bit
• Steamed green beans or roasted broccoli on the side

For portioning, I use a large serving spoon and scoop from one corner to the bottom to get those beautiful layers. The cheesy beef and macaroni casserole holds its shape beautifully when served this way.

Storage Instructions

Let any leftovers cool completely before storing. Transfer to an airtight container and refrigerate for up to 4 days.

To reheat individual portions, microwave for 1-2 minutes until heated through. For larger amounts, cover with foil and bake at 350°F (175°C) for 15-20 minutes. If the top looks dry, sprinkle a little extra cheese or add a tablespoon of milk before reheating.

Freezing Tips

This casserole freezes beautifully! Prepare it up to the baking step, then cover tightly with plastic wrap and foil. Freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator, then bake as directed, adding 5-10 minutes to the cooking time since it will be cold.

A safety note: Always make sure your casserole reaches an internal temperature of 165°F (74°C) when reheating. I keep a little kitchen thermometer handy—it’s one of my most-used tools!

Frequently Asked Questions

Q: Can I use a different type of pasta in this casserole?

Absolutely! While elbow macaroni is traditional, you can use any short pasta that holds sauce well. Shells, rotini, penne, or cavatappi all work beautifully. Just adjust the cooking time according to the package directions, remembering to cook it al dente since it will continue cooking in the oven.

Q: What's the best way to prevent the casserole from becoming dry?

A couple of tips: First, don't overcook the pasta—al dente is key. Second, make sure your sauce has thickened properly before combining everything. If it seems too thick, add a splash more broth or milk. Finally, don't skip the resting time after baking—this allows the casserole to set and the pasta to absorb any extra liquid.

Q: Can I make this cheesy beef and macaroni casserole ahead of time?

Yes, it's perfect for make-ahead meals! Prepare everything up to the baking step, cover tightly, and refrigerate for up to 24 hours. When ready to bake, you may need to add 5-10 minutes to the cooking time since it will be cold. You can also freeze the unbaked casserole for up to 3 months—just thaw in the refrigerator overnight before baking.

Q: What can I use instead of ground beef?

Ground turkey, chicken, or pork all work well. For a vegetarian version, use cooked lentils or a plant-based ground meat substitute. Just adjust the seasoning to match—if using poultry, you might want to add a bit more seasoning since it's milder than beef.

Q: How can I tell when the casserole is done baking?

Look for three signs: The edges should be bubbly, the cheese on top should be melted and lightly golden (not burned), and if you insert a knife into the center, it should come out hot. The internal temperature should reach 165°F (74°C). Remember that it will continue to cook a bit as it rests, so don't overbake it.
