- Use a high-quality, flavorful marinara sauce for the best taste.
- Baking time may vary. The meatballs are finished cooking when they reach 160°F internally.

How to Make Meatball Casserole Step by Step
Prep: Preheat your oven to 350°F.
Make the Meatballs: Add 1 pound of ground beef, 1 large egg, ¾ cup of breadcrumbs, 1 tablespoon of dried minced onions, 1 teaspoon of Italian seasoning, 1 teaspoon of garlic powder, 1 teaspoon of ground black pepper, and ½ teaspoon of kosher salt to a large bowl and stir to combine.
Shape the Meatballs: Form 3-inch balls from the mixture, then place them in a 9×13-inch baking pan.
Bake the Meatballs: Bake for 20 minutes.
Cover with Sauce: Pour 24 ounces (1 jar) of marinara sauce over the meatballs and stir to combine. Turn the oven down to 300°F and bake again for 20 minutes.
Top with Cheese: Sprinkle 8 ounces of freshly shredded mozzarella cheese around the meatballs and sprinkle ¼ cup of freshly grated Parmesan on top then bake for 10 more minutes. Serve over spaghetti and with freshly minced parsley for garnish if desired.
I like to use 80% lean ground beef, but you could also use a mix of ground veal, pork, and/or beef; ground turkey; or ground chicken!
Yes! Simply thaw the meatballs first and skip the initial 20-minute bake in step 4. Pour the sauce over and bake as directed in step 6.
Sure! Place everything (except the cheese) in a Crockpot and cook on high for 2-2½ hours or low for 3-4 hours. Sprinkle the cheese on top during the last few minutes of cooking to melt.
