How To Make Hamburger Casserole

Full ingredients and instructions are also in the recipe card at the bottom of this blog post.

STEP 1: Preheat oven to 350°F.

STEP 2: Add 3 cups uncooked spiral pasta to a pot of boiling water and cook according to package instructions. Cook al dente, then drain and set aside.

STEP 3: In a large pot over medium-high heat, cook 1 lb lean ground beef and 1 cup chopped yellow onion until beef is browned and onion turns translucent. Fold a paper towel and swish it around using a spatula to absorb any excess grease.

STEP 4: Now add 24 oz pasta sauce, 14 oz drained diced tomatoes, 2 cups sliced mushrooms, 1 teaspoon dried oregano, ½ teaspoon garlic powder, ½ teaspoon salt and ¼ teaspoon ground black pepper to the pot and stir everything together. Bring to a boil, then reduce heat to let simmer for 5 minutes.

STEP 5: Remove the pot from heat then add the cooked pasta noodles. Stir everything together.

STEP 6: Pour the mixture into a 9x11 casserole dish and spread evenly with a spatula. Sprinkle 1 cup shredded cheddar cheese over top, then sprinkle 1 cup shredded mozzarella cheese.

STEP 7: Bake uncovered for 25-30 minutes or until the cheese is melted and bubbly. Let cool for 5 minutes then scoop onto plates and serve.

How do you know when hamburger casserole is cooked? Because the ground beef is already cooked in advance, there’s no need to worry about an undercooked hamburger casserole. Baking at 350°F for 30 minutes is enough time to ensure that the casserole is fully warmed through and the cheese is melted and bubbly.

Should I cover my hamburger casserole with foil while baking? Some people prefer to cover their casserole with foil for 20 minutes and then remove it for the last 10 minutes. I haven’t had any problems with baking without foil for the full 30 minutes so I stick with that method. It’s just personal preference.

How To Store Leftovers

• Refrigerate - Let the hamburger casserole cool completely, then cover it with plastic wrap and chill in the fridge up to 4-5 days.
• To Freeze - You can slice pieces into squares and individually wrap them in plastic wrap. Add them to a freezer bag and store in the freezer for future meals.
