Ground Beef Casserole with Mozzarella Recipe

There’s something so comforting about a bubbling casserole loaded with hearty ground beef and gooey melted cheese that wraps you in warmth. This Ground Beef Casserole with Mozzarella Recipe has been my go-to for busy weeknights when I want something satisfying but fuss-free, and every time it comes out just right—rich, cheesy, and perfectly saucy.

Ingredients You’ll Need

Each ingredient in this Ground Beef Casserole with Mozzarella Recipe plays a specific role, balancing richness, texture, and hearty flavor. I always recommend using high-quality marinara and fresh mozzarella for the best melty goodness.

• Marinara sauce: Go for a quality jarred sauce or homemade if you have it—it forms the flavorful base of the casserole.
• Half and half: Adds creaminess to the sauce without being too heavy; you can also use heavy cream for a richer texture.
• Worcestershire sauce: A secret boost of umami that deepens the meaty flavor beautifully.
• Hot sauce: Just a dash wakes up the sauce without making it spicy—Frank’s is my personal favorite.
• Dried herbs (oregano, basil, parsley): Classic Italian herbs that make the sauce aromatic and fresh-tasting.
• Mustard powder: Adds subtle tang and complexity—don’t skip it!
• Ground beef: Use fresh, lean but not too dry for tender, juicy bites.
• Yellow onion: Adds sweetness and depth when sautéed with the beef.
• Garlic: Essential aromatic that brightens the whole dish.
• Tomato paste: Concentrated tomato flavor to intensify the sauce.
• Beef broth: Used to build layers of savory flavor and help create a luxurious sauce.
• Parmesan cheese: Adds salty, nutty notes—grate fresh if possible.
• Mozzarella cheese: Use low moisture, whole milk, shredded from a block for best melt and flavor.
• Penne pasta: Great for holding onto sauce with its tube shape, but feel free to swap for ziti or rigatoni.

Variations

I love playing around with this Ground Beef Casserole with Mozzarella Recipe, customizing it depending on what’s in my fridge or who’s coming over. Don’t hesitate to make it your own—it’s so forgiving!

• Add veggies: I’ve tossed in diced green bell peppers or sliced mushrooms with the onions for extra flavor and nutrition—always a hit.
• Meat swap: Mixing ground pork, veal, or even Italian sausage with the beef adds complexity. Sometimes I go half beef, half sausage for a slightly spicy kick.
• Spicier twist: If you like heat, add diced Rotel tomatoes or double up on that hot sauce; it gives the casserole a nice zing.
• Cheese variations: Try adding a handful of shredded provolone or swapping half the mozzarella for fontina for a different melty texture.

How to Make Ground Beef Casserole with Mozzarella Recipe

Step 1: Prep the flavorful sauce base

Start by combining the marinara sauce, half and half, Worcestershire, hot sauce, and dried herbs in a bowl and set it aside. I like prepping this sauce first because it lets all the seasonings marry while you’re cooking other parts. It really sets the tone for the whole casserole.

Step 2: Cook the beef mixture

Season the ground beef well with salt and pepper—don’t be shy because seasoning is key here. In a large skillet over medium-high heat, cook the beef, breaking it up as it browns. After about 3 minutes, toss in the diced onion and minced garlic. Keep stirring until the beef is cooked through and the onions are soft, about 5 to 6 minutes more. Drain the excess grease—this keeps the dish from getting greasy and helps the flavors shine.

Step 3: Build the sauce right in the skillet

Stir in the tomato paste and cook it for a minute or two to bring out its deep flavor. Pour in beef broth, then scrape the browned bits off the bottom of the pan using a spatula—this little trick adds so much depth! Let the liquid reduce by about half, around 3 to 4 minutes.

Step 4: Simmer with prepared sauce

Pour the sauce mixture you set aside into the skillet and bring it all to a gentle simmer. Let it bubble uncovered while you start boiling your pasta. I always set a timer to ensure the pasta only cooks until just shy of al dente because it’ll finish cooking in the oven and I don’t want mushy noodles.

Step 5: Combine pasta, cheese, and sauce

Stir the Parmesan and a quarter cup of mozzarella into the sauce for extra cheesy flavor. Drain the pasta and toss it right into the skillet sauce to coat every bit. Then spread the whole mixture into a lightly greased 9 x 13-inch casserole dish and sprinkle the remaining mozzarella on top.

Step 6: Bake and broil to perfection

Bake the casserole uncovered at 375°F for 10 minutes. If you want a beautifully browned top, switch your oven to broil at 450°F for 1 to 2 minutes—but watch it super closely so it doesn’t burn! Once done, let it stand a few minutes before digging in. I like to sprinkle fresh parsley on top for a pop of color and freshness.

How to Serve Ground Beef Casserole with Mozzarella Recipe

Garnishes

I usually sprinkle freshly chopped parsley over the casserole just before serving because it adds a fresh color and brightens the rich flavors. Sometimes I add a little grated Parmesan too if we’re feeling extra cheesy that day!

Side Dishes

This casserole pairs beautifully with a crisp green salad dressed with vinaigrette and some crusty garlic bread with melted cheese—it’s a combo that my family can’t get enough of. Roasted veggies or steamed green beans are also simple, healthy sides that complement the richness.

Creative Ways to Present

For special occasions, I like to serve this casserole in individual ramekins and garnish with a fresh basil leaf or a small dollop of ricotta for an elegant touch. It makes the dish feel homemade yet fancy enough for guests.

Make Ahead and Storage

Storing Leftovers

I store any leftovers in an airtight container in the fridge and they last beautifully for about 3 days. The flavors deepen overnight, which means the next-day casserole is often tastier than freshly baked!

Freezing

This recipe freezes wonderfully—just make sure you cook the pasta slightly less than al dente before assembling. Freeze in a sealed container for up to 3 months. When you’re ready, thaw in the fridge overnight before reheating.

Reheating

To reheat, I cover the casserole with foil and warm it in a 350°F oven for about 15-20 minutes or until heated through. This helps keep the pasta from drying out. If you want the cheese melty again, remove the foil for the last 5 minutes.
