Dump and Bake Meatball Casserole Ingredients
For the Casserole
• Uncooked Penne Pasta – This forms the hearty base of the dish; feel free to swap it for short pasta like rotini or rigatoni for a fun twist.
• Marinara Sauce – A rich flavor source that brings moisture; choose your favorite store-bought or homemade sauce to make it your own.
• Water (or Beef Broth) – Essential for cooking the pasta and melding flavors; using broth will elevate the taste profile.
• Frozen Meatballs – These are your main protein and can be added directly from the freezer; consider using homestyle or Italian-style for added flavor.
• Italian Seasoning – This adds a classic herby aroma; a pinch of red pepper flakes can introduce a delightful heat.
• Garlic Powder (optional) – Deepens the savory flavor; omit if you prefer a more straightforward taste.
• Onion Powder (optional) – Enhances the overall flavor; adjust according to your liking or leave it out for simplicity.
• Shredded Mozzarella Cheese – Melts beautifully to create that gorgeous gooey top; it’s a must for cheesiness!
• Grated Parmesan Cheese – Adds a rich, salty depth; Romano cheese works well as a substitute if you prefer.
• Fresh Parsley – Just for garnishing, this adds a pop of freshness and color right before serving.
Step‑by‑Step Instructions for Dump and Bake Meatball Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 425°F (220°C). While the oven warms up, lightly grease a 9×13-inch baking dish with cooking spray or olive oil to prevent sticking. This simple preparation sets the stage for your Dump and Bake Meatball Casserole and ensures easy cleanup afterward.
Step 2: Combine Ingredients
In the greased baking dish, mix together the uncooked penne pasta, marinara sauce, and water (or beef broth). Stir in the frozen meatballs along with the Italian seasoning, garlic powder, and onion powder. Ensure the pasta is evenly coated in the sauce, creating a delicious foundation for this casserole to bake beautifully.
Step 3: Cover and Bake
Once the ingredients are thoroughly combined, cover the dish tightly with aluminum foil. Place it in the preheated oven and bake for 35-40 minutes. Keep an eye out for the pasta to become tender during this time, as this ensures your Dump and Bake Meatball Casserole will have the perfect texture.
Step 4: Add Cheese and Finish Baking
After baking, carefully remove the foil and sprinkle shredded mozzarella and grated Parmesan cheese generously over the top of the casserole. Return the dish to the oven, uncovered, for an additional 10-15 minutes. Look for the cheese to melt and bubble, creating a golden, gooey topping that adds to the comfort of this dish.
Step 5: Rest Before Serving
Once the cheese is perfectly melted, take the casserole out of the oven and let it rest for 5-10 minutes. This resting period allows the flavors to set and makes it easier to serve portions of the Dump and Bake Meatball Casserole without losing its delicious structure. Enjoy!
