1. Ground Beef Casserole Recipe (Yield: 6 Servings)
Ingredients
- 1 pound uncooked penne
- 1 tablespoon olive oil
- 1 pound lean ground beef
- 1/2 medium onion, chopped
- 1 clove garlic, minced
- 1.5 cups marinara sauce
- Salt & pepper to taste
- 1.5 cups shredded cheddar cheese
Instructions
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a little oil or nonstick spray, then set it aside.
Bring a large pot of salted water to a boil. Add the uncooked penne and cook it until it is just al dente, following the package instructions. This is important because the pasta will continue to soften as it bakes in the oven. Once cooked, drain the pasta and set it aside.
Next, place a large skillet over medium heat and add the olive oil. Once the oil is warm, add the chopped onion and cook for about 3 to 4 minutes, stirring often, until it begins to soften and turn slightly translucent.
Add the minced garlic and stir for about 30 seconds. Garlic cooks quickly, so keep stirring so it doesn’t burn.
Now add the ground beef to the skillet. Break it up with a spoon or spatula and cook until it is browned and no longer pink, usually around 6 to 8 minutes. If your beef releases excess grease, carefully drain most of it off so your casserole doesn’t become oily.
Once the beef is cooked, season it with salt and pepper to taste. Pour in the marinara sauce and stir everything together until the meat mixture is evenly coated. Let the sauce simmer gently for about 2 minutes, just to blend the flavors.
Add the drained penne pasta into the skillet and stir until the pasta is well mixed with the meat sauce. Make sure everything is evenly coated so every bite is flavorful.
Pour the mixture into your prepared baking dish and spread it out evenly. Sprinkle the shredded cheddar cheese all over the top, covering the casserole completely.
Place the dish into the preheated oven and bake for about 18 to 22 minutes, or until the cheese is fully melted and bubbly around the edges.
Once baked, remove the casserole from the oven and let it rest for about 5 to 10 minutes before serving. This helps it set up slightly so it’s easier to scoop and serve.
Serve warm and enjoy a cheesy, hearty dinner that tastes like comfort food at its best.

2. Tips for Perfect Ground Beef Casserole
To make the best ground beef casserole every time, a few small tricks can make a big difference.
First, cook your pasta only until al dente. If you boil it too long, it will turn soft and mushy after baking. Slightly firm pasta gives the casserole a better texture.
Using lean ground beef is also helpful because it keeps the casserole from becoming too greasy. If you use regular ground beef, make sure you drain off the extra fat after browning.
For extra flavor, don’t rush the onion and garlic. Letting the onion soften properly adds sweetness and depth to the meat sauce. Garlic should be added at the end so it stays fragrant instead of bitter.
Cheddar cheese is a classic choice, but shredding it yourself from a block will melt smoother than pre-shredded cheese. Pre-shredded cheese often contains anti-caking agents that affect melting.
Finally, let the casserole rest before serving. It will hold its shape better, and the flavors will settle nicely instead of sliding apart on the plate.
3. Frequently Asked Questions
Can I make ground beef casserole ahead of time?
Yes, this is a great make-ahead meal. You can assemble everything in the baking dish, cover it tightly, and refrigerate it for up to 24 hours. When you’re ready to bake, let it sit at room temperature for about 15 minutes, then bake as directed.
What can I add to make this casserole more filling?
If you want to bulk it up, you can stir in cooked vegetables like mushrooms, zucchini, spinach, or bell peppers. These additions make the casserole heartier without overpowering the flavor.
Can I use a different pasta instead of penne?
Absolutely. Rotini, rigatoni, ziti, or elbow macaroni all work well. The best pasta choices are shapes that hold sauce nicely and don’t fall apart after baking.
How do I keep the casserole from drying out in the oven?
The key is using enough sauce and covering the pasta well before baking. If your marinara sauce is thick, you can add a small splash of water or broth before baking. Also, avoid baking too long, since that can dry out the pasta.
Can I freeze ground beef casserole after baking?
Yes, this casserole freezes very well. Let it cool completely, then wrap it tightly or store it in an airtight container. It will keep in the freezer for up to 2 months. Thaw overnight in the fridge and reheat in the oven until hot and bubbly.
