How to Make Classic Meatball Casserole
Combine Ingredients: In a large bowl, gently combine 1½ lbs lean ground beef, 1½ tsp salt, ¼ tsp black pepper, 1 egg, 1 tbsp dried minced onion, and ½ cup breadcrumbs until everything is just mixed. Avoid overworking the meat to keep the meatballs tender, then form them into 1-inch meatballs.
Brown Meatballs: Heat 1 tbsp oil in a large skillet over medium heat. Add the meatballs and let them brown evenly on all sides, about 7-10 minutes. Once cooked, remove them from the skillet and set aside on a plate.
Make Sauce: Drain excess fat from the skillet, leaving about 3 tbsp drippings. Stir in 3 tbsp flour and cook for 1 minute to create a light roux. Gradually whisk in the 15 oz can of diced tomatoes along with the juices, 1 cup water, ½ tsp salt, 2 tsp sugar, and 1 tsp dried basil leaves. Cook until the sauce thickens slightly, about 3-5 minutes, and turns fragrant.
Mix in Veggies: Add 1½ lbs halved baby potatoes, 1 cup chopped carrots, 1 medium yellow onion, and 2 celery stalks to the thickened sauce and gently stir to coat. Return the browned meatballs to the skillet, ensuring everything is nestled nicely in the savory sauce.
Bake: Transfer the entire mixture to a large casserole dish and cover it tightly with foil. Bake in a preheated oven at 375°F for 1 hour, or until the potatoes and carrots are tender and the meatballs are fully cooked through, and oozing with flavor.
Serve: Allow the casserole to rest for about 5 minutes before serving. Enjoy it warm with crusty bread or a crisp salad for a complete meal!

Storing & Reheating
To store leftovers, place the casserole in an airtight container in the refrigerator for up to 3 days. If you want to freeze it, transfer the cooled casserole to a freezer-safe container; it can be stored for up to 3 months. To reheat, simply cover and warm in a 350°F oven for about 25-30 minutes, or until heated through. While the texture might be a tad different after freezing, refreshing it with a splash of water will help bring some moisture back.
Chef’s Helpful Tips
- Avoid over-mixing the meat when forming meatballs to keep them tender.
- Use room temperature eggs for better binding in meatballs.
- If the sauce seems too thick, add a bit more water during cooking to reach desired consistency.
- Adding fresh herbs right before serving brightens the dish.
- Consider doubling the recipe for larger gatherings; this casserole is perfect for feeding a crowd.
