How to Make one pan meatball casserole
Prepare the Meatballs: Preheat your oven to 375°F (190°C). In a large mixing bowl, combine ground beef, breadcrumbs, Parmesan cheese, eggs, salt, pepper, and Italian seasoning until well mixed but not overworked.
Shape the Meatballs: Roll the mixture into equal-sized balls (about 1 inch wide) using your hands—think of them as tiny flavor-packed orbs ready to join forces with marinara.
Sauté the Veggies: In a large skillet over medium heat, add olive oil. Sauté diced bell peppers and zucchini until tender and fragrant—this should take about 5 minutes.
Add Marinara Sauce: Pour marinara sauce over sautéed veggies in the skillet. Gently stir everything together until evenly coated. Watch those colors come alive!
Add Meatballs: Carefully nestle the prepared meatballs into the sauce mixture. Make sure they are submerged so they soak up all those glorious flavors while baking.
Bake & Top with Cheese: Bake uncovered for 25-30 minutes or until meatballs are cooked through (internal temperature should reach 160°F/70°C). Sprinkle shredded mozzarella on top during the last 5 minutes of baking for melty perfection.
This one pan meatball casserole is not just any dish; it’s an experience filled with laughter and love at every bite! Enjoy every delicious mouthful while soaking up those memories around your dinner table!
