Nothing screams a comforting home-cooked meal quite like a delicious casserole. This easy ground beef casserole is a family-favorite of ours, and it's sure to be a hit in your house, too!

Pasta noodles are coated in saucy ground beef, topped with cheese, and baked in the oven. It's simple, yet the flavor is anything but.

🥘 Ingredients

You only need a few simple ingredients for this casserole. I always keep ground beef in the freezer so I can make a crowd-pleasing casserole like this one on days I don't have dinner planned.

• Penne Pasta - 1 pound, uncooked pasta.
• Ground Beef - 1 pound of hamburger. I prefer 80/20 ground chuck, but you can use leaner ground beef if you like.
• Onion - 1 cup chopped white or yellow onion, or ½ teaspoon onion powder or ½ tablespoon of dried minced onion (*see note).
• Garlic - ½ teaspoon (about 1 clove) of minced garlic.
• Marinara - 1 ½ cups, or 12 ounces, of marinara sauce.
• Salt & Pepper - ¼ teaspoon of both salt & pepper or more, to taste. Plus, some to salt the pasta water.
• Cheddar Cheese - 1 ½ cups of shredded cheddar cheese (4.5 ounces if there are 3 ounces per cup using a medium grate.)

🔪 How To Make Ground Beef Casserole

Just brown the ground beef, boil the pasta, combine, and bake. To get started, you will need a 9x13 baking dish, a colander, and a skillet.

This casserole will serve 6 but don't worry if you have some leftovers. It is even better the next day.

Cook The Penne Pasta

1. Preheat. Move a rack in your oven to the middle position and preheat your oven to 400°F (204°C). Grease a 9x13 baking dish with non-stick cooking spray.
2. Boil the pasta. Bring a large pot of salted water (*see note) to a boil. Add 1 pound of penne pasta and boil for 10 minutes. It should be just under al dente when you drain the water because the pasta will continue to cook while baking.

Brown the Ground Beef & Mix With Marinara

1. Brown the beef. As the pasta boils, add 1 pound of ground beef and 1 cup of chopped onion (*see note) to a skillet over medium-high heat. Break up the meat as it browns for 10 minutes. A few minutes before the meat is done browning, add ½ a teaspoon of minced garlic. *Spoon out any excess fat as needed.
2. Add marinara. Once the beef is browned, mix in 1 ½ cups of marinara sauce and let it heat until warmed through. Taste the sauce and beef mixture and add ¼ teaspoon of salt & pepper or more as needed.

Assemble the Casserole

1. Combine. Pour the cooked, drained pasta into the baking dish, followed by the marinara and beef mixture. Toss to combine. Sprinkle 1 ½ cups cheddar cheese over the top in an even layer (*see note).
2. Bake and serve. Bake, uncovered, at 400°F (204°C) for 15 minutes or until all of the cheese is gooey and melted (*see note). Serve immediately.

💭 Tips & Notes

• I opted for dried minced onion and added it to the beef after 5 minutes of cooking (it should take 6-8 minutes total to brown ground beef) before draining the excess fat so that it could take on the pan juices to re-hydrate.
• When salting the pasta water, use 1 ½ tablespoons of salt per pound of pasta with 3-4 quarts (12-16 cups) of water. For instance, I use 12 cups of water with 1 ½ tablespoons of salt.
• If you want your casserole extra cheesy, mix in an additional ½ cup of cheese with the pasta and sauce before you top it with the remaining cheese.
• Optionally, you may pop the casserole under the broiler for a few minutes at the end of cooking time to brown the cheese some.
• Storing: Cover the baking dish with plastic wrap or foil and refrigerate for up to 3 days. Leftovers can be frozen in heavy-duty freezer bags or a freezer-safe airtight container for up to 3 months. 
• Reheating: Reheat individual portions in the microwave or the entire casserole in the oven at 350°F (175°C) for 15-20 minutes, or until heated through.
