Simple Ground Beef Casserole Recipe: Easy and Delicious
Ingredients
Method
- Set your oven to 400 degrees Fahrenheit and place the rack in the center. Lightly coat a 9×13 inch baking dish with cooking spray.
- Bring a large pot of salted water to a boil and cook the penne for about 10 minutes, ensuring it remains slightly firm to avoid mushiness.
- In a skillet, heat the olive oil over medium-high heat, then add the ground beef and chopped onion. Cook for around 10 minutes, breaking the meat apart as it browns. Stir in the minced garlic partway through cooking. Remove some excess fat if necessary.
- Add the marinara sauce to the skillet and heat through. Taste and season with salt and pepper as preferred.
- Drain the cooked pasta and transfer it to the prepared baking dish. Pour the beef sauce over the pasta and gently mix until evenly combined.
- Sprinkle an even layer of shredded cheddar cheese over the casserole. For extra cheesiness, mix in an additional half cup of cheese before topping.
- Bake uncovered for 10 minutes until the cheese melts thoroughly. Optionally, switch to the broiler for a few minutes to get a golden, bubbly cheese crust. Serve hot.

FAQs ( Simple Ground Beef Casserole )
Can I make this casserole ahead of time?
Yes, you can assemble this dish up to 24 hours in advance and store it covered in the refrigerator. Add about 10 extra minutes to the baking time if putting it straight from the fridge into the oven. This makes it perfect for busy weeknight dinners or meal prep.
What type of ground beef works best?
I recommend using 80/20 or 85/15 ground beef for the best flavor and moisture balance. Leaner beef can make the dish dry, while fattier blends may require draining excess grease. Always brown the meat thoroughly and drain before adding to your casserole.
Can I freeze leftovers?
Absolutely! This recipe freezes beautifully for up to 3 months. Cool completely, then wrap tightly in foil or transfer to freezer-safe containers. Thaw overnight in the refrigerator and reheat covered at 350°F until warmed through.
What vegetables can I add to this dish?
Bell peppers, corn, green beans, diced tomatoes, and mushrooms all work wonderfully. Just sauté firmer vegetables like peppers with the beef, or fold in frozen veggies before baking. This is a great way to sneak extra nutrition into dinner.
How do I keep the cheese from getting greasy?
Use freshly shredded cheese instead of pre-shredded, which contains anti-caking agents that can cause separation. Add the cheese during the last 10-15 minutes of baking rather than at the beginning. Let the dish rest for 5 minutes after baking so the cheese can set properly.
