How to Make Classic Meatball Casserole
Mix Ingredients: In a large bowl, combine 1½ lbs lean ground beef, 1½ tsp salt, ¼ tsp black pepper, 1 egg, 1 tbsp dried minced onion, and ½ cup breadcrumbs. Mix gently until just combined and form the mixture into 1-inch meatballs. You want to handle the meatballs lightly to keep them tender.
Brown the Meatballs: Heat 1 tbsp olive oil in a large skillet over medium heat. Add the meatballs and brown them on all sides, which should take about 5 minutes. Once browned, remove the meatballs and set them aside. This step gives the meatballs great flavor while keeping them moist.
Prepare the Sauce: Drain any excess fat from the skillet, leaving about 3 tbsp of drippings. Stir in 3 tbsp flour and cook for 1 minute to create a light roux. Slowly whisk in 1 (15 oz) can diced tomatoes with juices, 1 cup water, ½ tsp salt, 2 tsp granulated sugar, and 1 tsp dried basil. Cook until the sauce thickens slightly and becomes fragrant, about 3-5 minutes.
Combine Ingredients: Add in 1½ lbs halved baby potatoes, 1 cup chopped carrots, 1 medium yellow onion chopped into large chunks, 2 chopped celery stalks, and the browned meatballs to the sauce. Stir gently to coat everything with the delicious tomato sauce. This part is where all the flavors meld together beautifully.
Bake the Casserole: Transfer the mixture to a large casserole dish, cover tightly with foil, and bake at 375°F for 1 hour. You’ll know it’s done when the vegetables are tender and the meatballs are cooked through. Cooking with the foil on helps the vegetables steam and prevents drying out, preserving that delightful texture.
Rest and Serve: Allow the casserole to rest for 5 minutes before serving. It’s a fantastic option paired with crusty bread or a fresh side salad. Dive in and enjoy the rich, comforting flavors!

Storing & Reheating
Store any leftovers at room temperature for up to 2 hours. For refrigerator storage, transfer to an airtight container where it will keep well for about 3-4 days. If you want to enjoy it later, freeze the casserole in a freezer-safe container for up to 3 months. To reheat, place in the oven at 350°F for 20-25 minutes or until warmed through, topping with a sprinkle of fresh herbs to refresh the dish.
Chef’s Helpful Tips
- Avoid overmixing the meatball mixture to keep them light and tender.
- If you prefer a thicker sauce, add an extra tablespoon of flour or cornstarch during the cooking process.
- Letting the casserole sit for a few minutes after baking allows the flavors to deepen and the sauce to settle, making each serving even better.
- Experiment by adding different veggies based on what you have on hand, like bell peppers or green beans, for an added nutrition boost!
- Making it ahead? Prepare the casserole the night before and bake it the following day for a hassle-free meal.

Certainly! You can swap the ground beef for a plant-based alternative like lentils or a store-bought meat substitute. Don’t forget to ensure your breadcrumbs are also plant-based!
What can I serve with meatball casserole?
This dish pairs wonderfully with a simple side salad or some crusty bread for soaking up the delightful sauce. You can also add a light vegetable side dish, like steamed broccoli, for extra nutrition.
How do I know when the meatballs are fully cooked?
To ensure your meatballs are cooked through, they should reach an internal temperature of 160°F. Use a meat thermometer to check for accuracy, or cut one open; they should be evenly browned and no pink should remain inside.
