Ground Beef Casserole
This cozy, cheesy ground beef casserole is packed with tender pasta, a rich garlic-herb tomato sauce, and a velvety blanket of melted cheese. It is the ultimate fuss-free weeknight dinner that your family will beg for week after week.
- Undercooking the pasta prevents it from turning mushy during the baking process.
- Searing the beef and draining excess fat ensures a rich, concentrated meat sauce without greasiness.
- A blend of sharp cheddar and low-moisture mozzarella creates the ultimate gooey cheese pull.
I remember the rainy Tuesday in October when my oven heating element literally snapped in half with a dramatic purple spark, leaving me with half-cooked pasta and raw ground beef.
It was a disaster.
I had to finish everything in a battered cast-iron skillet on the stovetop, throwing in whatever cheese ends were lingering in the crisper drawer.
Surprisingly, my family devoured it faster than any elaborate Sunday roast I had ever spent hours sweating over. That chaotic night taught me that comfort food doesn't need a pristine kitchen or a fancy plan to be absolutely perfect.
Most ground beef casseroles suffer from a tragic, watery grave because home cooks dump raw ingredients straight into the baking dish. When you bake beef without properly rendering the fat first, the meat boils in its own juices instead of browning, destroying any chance of a rich protein matrix. This brand of cheap pre-packaged beef failed every single test because the excess water content ruined the sauce, a common issue I also solved when perfecting my Cheeseburger French Fry Casserole.
Bear with me here, because the physics of starch gelatinization is fascinating.
If you overcook your pasta before it even hits the oven, it will absorb the sauce like a sponge and turn into baby food. We want to boil the noodles until they are incredibly underdone so they finish cooking in the savory tomato juices.
Trust me on this one.
We are going to build a quick, velvety sauce right in the same pan we browned the beef in, scraping up all those delicious caramelized bits. Press your wooden spoon into the corners of the pan to catch every ounce of flavor. If you want an even richer version, check out our Creamy Ground Beef Casserole.
Ground Beef Casserole
Ingredients
- 1 lb lean ground beef (90/10 blend)
- 8 oz penne pasta
- 1/2 medium yellow onion, finely diced
- 2 cloves garlic, minced
- 1 tsp Diamond Crystal kosher salt
- 1/2 tsp freshly cracked black pepper
- 1 can (15 oz) tomato sauce
- 1 can (14.5 oz) diced tomatoes, undrained
- 1 tsp dried Italian seasoning
- 1.5 cups shredded sharp cheddar cheese, divided
- 1 cup shredded low-moisture mozzarella cheese
Directions
- Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with non-stick spray or a smear of butter.
- Bring a large pot of salted water to a rolling boil. Cook the pasta for 2 minutes less than the package directions for al dente; it should still have a firm bite in the center. Drain and set aside.
- Heat a large skillet over medium-high heat. Add the ground beef and diced onion, breaking the meat up with a wooden spoon, until the beef is browned and the onion is translucent, about 6-8 minutes. Drain any excess grease.
- Stir in the minced garlic, Diamond Crystal kosher salt, black pepper, and Italian seasoning. Cook for 1 minute until fragrant.
- Pour in the tomato sauce and diced tomatoes. Simmer on low heat for 5 minutes, allowing the flavors to meld and the sauce to thicken slightly.
- Remove the skillet from the heat. Stir in the cooked pasta and half of the cheddar cheese until melted and well combined.
- Transfer the mixture to the prepared baking dish. Spread it into an even layer, pressing down gently.
- Top evenly with the remaining cheddar and all of the mozzarella cheese. Bake for 20 minutes until the cheese is melted, bubbly, and golden brown around the edges. Let cool for 5 minutes before serving.
Notes
- I highly recommend using Diamond Crystal Kosher Salt. If you only have standard table salt, cut the measurement in half (use 1/2 teaspoon instead of 1 teaspoon) to avoid an overly salty dish.
- Undercooking the pasta is crucial because of starch gelatinization. The pasta will continue to absorb liquid and cook inside the oven; starting with fully cooked pasta guarantees a mushy, structurally compromised casserole.
- Keep a close eye on the garlic during step 4. Garlic burns in under 30 seconds in a hot pan, which will impart a bitter, metallic taste to your entire sauce matrix.
- After a day in the fridge, the pasta will absorb even more moisture from the sauce. To revive its saucy glory during reheating, splash a tablespoon of water or beef broth over the top before microwaving.
Serving Suggestions
Complete this comforting meal with simple, fresh sides that balance the rich, cheesy layers of the bake.
- Serve with a side of Garlic Bread Grilled Cheese for the ultimate carb-on-carb comfort experience.
- A crisp green salad tossed with a light vinaigrette cuts through the rich, cheesy layers beautifully.
- Roasted broccoli or green beans add a nice, charred crunch to the plate.
- Top with a sprinkle of fresh chopped parsley or basil right before serving for a pop of color and freshness.
Storage and Reheating
Store any leftover casserole in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen overnight as the pasta continues to marry with the garlic and tomato compounds.
It makes the best desk lunch.
To reheat, place a portion in an oven-safe dish, cover with foil to trap the steam, and bake at 350°F for 15 minutes.
If you are in a rush, the microwave works perfectly fine too. Just make sure to cover the plate with a damp paper towel to keep the cheese from turning into a rubbery, dried-out sheet.
Ingredient Substitutes
If you need to make some quick adjustments based on what is currently in your pantry, these simple swaps work beautifully:
- Ground Beef: Swap for ground turkey or sweet Italian sausage for a different flavor profile.
- Penne Pasta: Any short-cut pasta like rotini, cavatappi, or medium shells will work beautifully.
- Cheddar Cheese: Colby Jack or Monterey Jack make excellent, meltable alternatives.
- Diced Tomatoes: Use crushed tomatoes if you prefer a smoother, less chunky sauce texture.
This casserole is the culinary equivalent of a warm hug on a stressful day. It is forgiving, endlessly customizable, and guaranteed to leave everyone at the table completely satisfied. Grab your favorite baking dish and let's get cooking!
