Dump-and-Bake Meatball Casserole Ingredients
For the Casserole
• Uncooked short pasta (1 lb) – Use penne, ziti, or rigatoni; substitute with gluten-free pasta if needed.
• Marinara or pasta sauce (1 jar, 24–26 oz) – This adds moisture and flavor; feel free to use homemade or your favorite store-bought sauce.
• Water or low-sodium beef broth (3 cups) – Broth enhances flavor while baking; water is a lighter choice.
• Frozen pre-cooked meatballs (1 lb, about 20–25 meatballs) – Convenient protein source; no need to thaw, but homemade meatballs can be used.
• Garlic powder (1 tsp) – A quick way to add flavor; fresh garlic can be used if preferred (adjust amount).
• Italian seasoning (1 tsp) – Offers herbal notes; swap with mixed herbs for a different twist.
• Salt (1/2 tsp) and black pepper (1/4 tsp) – Essential for seasoning; adjust to your taste.
For the Toppings
• Shredded mozzarella (2 cups, about 8 oz) – Provides a creamy, melted topping; dairy-free options are available.
• Grated Parmesan (optional, 1/2 cup, about 2 oz) – Deepens flavors; can be omitted if desired.
• Fresh parsley (2 tbsp, chopped, for garnish) – Adds brightness and freshness; totally optional but recommended for color.
How to Make Dump-and-Bake Meatball Casserole
-
Preheat the oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish. This ensures your casserole doesn’t stick and makes for easy serving.
-
Mix together the uncooked pasta, marinara sauce, 3 cups of water or broth, garlic powder, Italian seasoning, salt, and pepper in the baking dish. Stir well to ensure all pasta is coated and submerged.
-
Nestle the frozen meatballs into the pasta mixture, spacing them evenly throughout for even cooking. There’s no need to thaw; they’ll cook beautifully in the oven.
-
Cover the dish tightly with aluminum foil, crimping the edges to seal in steam. Bake for 35–40 minutes, allowing the pasta to absorb the flavors and cook properly.
-
Check your casserole after baking. Carefully remove the foil to ensure the sauce is bubbling and that the pasta is mostly tender—it should look inviting and smell heavenly!
-
Sprinkle the mozzarella and optional Parmesan evenly over the top. Return the dish to the oven uncovered for 10–15 minutes or until the cheese is melted and golden brown.
-
Broil for an additional 1–2 minutes if you desire a golden, bubbly finish. Keep a close eye to prevent burning!
-
Cool for 10–15 minutes before serving; this helps set the casserole and makes it easier to slice. Garnish with fresh parsley for a pop of color and flavor.
Optional: Add a sprinkle of red pepper flakes for an extra kick!
