Ingredient Notes and Substitutions
- Ground beef: use ground beef with a little fat in it for flavor
- Onion: preferably yellow for sweetness
- Bell pepper: any color bell pepper works
- Garlic: fresh, of course
- Seasonings: Italian, kosher salt, and freshly ground black pepper
- Tomato sauce: or crushed tomatoes
- Fire-roasted diced tomatoes: I love the extra flavor and color
- Elbow macaroni: use any short pasta shape with this recipe, including rotini, elbow macaroni, farfalle, penne, egg noodles, or cellentani pasta.
- Cheese: cheddar, Monterey Jack, or a Mexican blend cheese works well
How to make Hamburger Casserole
Bring a large pot of lightly salted water to a boil. Cook the elbow macaroni al dente according to package instructions. Drain well in a colander in the sink.
Meanwhile, brown the ground beef in a large skillet over medium-high heat. Add the onion and red bell pepper about halfway through the browning process. Continue cooking until the veggies are soft and the ground beef is browned. Drain any excess grease. Reduce the heat to low and add the garlic and Italian seasoning, cooking for 1 minute while stirring constantly.
Stir in the tomato sauce, fire-roasted diced tomatoes, and cooked macaroni. Simmer for a couple of minutes. Season with kosher salt and fresh ground black pepper to taste. Spoon the ground beef mixture into a 9×13-inch casserole dish. Top with a mixture of shredded cheddar cheese and shredded Monterey Jack cheese. Cover and bake for 15 minutes. Then remove the foil and bake for another 5 minutes.
Preparation Tips
- Cook the noodles al dente, which means slightly firm. They will be simmered for a few minutes and then baked.
- You can substitute Italian sausage, ground turkey, ground chicken, or ground pork.
- Cook in the oven long enough to heat the casserole and melt the cheese.
- Other cheeses to try include provolone, Parmesan, Fontina, mozzarella, and, if you like spicy things, Pepperjack.
Hot to Freeze This Casserole
Already baked: First, let the casserole fully cool. Then, wrap the dish in several layers of plastic wrap. Place on a level shelf in the freezer and freeze for up to 3 months. Thaw in the fridge overnight, and remove the casserole from the fridge 40 minutes before baking to bring it to room temperature. Reheat at reduced power in the microwave.

Storage and Reheat
Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, cover the dish with foil and place it in a 350-degree oven for about 15 minutes or until heated through.
Alternatively, reheat in the microwave at reduced power for short increments until warm. It is always best to remove the casserole from the refrigerator 40 minutes before reheating to bring it to room temperature.
