Step-by-Step Instructions

Making this casserole is straightforward, even on busy weeknights. Here’s a quick guide:

1. Preheat and prepare your dish: Set your oven to 450°F (232°C). Spray a 4-quart baking dish with cooking spray to prevent sticking.
2. Roast the vegetables: Combine cauliflower, mushrooms, peppers, and onions in the dish. Spray generously with cooking spray and roast for 30–35 minutes until the cauliflower is tender.
3. Prepare the creamy sauce: While the vegetables roast, blend pasta sauce, cream cheese, and your favorite salt-free seasoning in a food processor until smooth. This creates a rich, cheesy coating that will cling to every bite.
4. Combine ingredients: Remove the vegetables from the oven. Add the thawed meatballs and fold in the creamy mixture until everything is well-coated. Sprinkle with shredded pizza cheese for extra flavor.
5. Bake to perfection: Return the casserole to the oven for 10–12 minutes, or until the meatballs reach 165°F and the edges are bubbly. Let it sit for 5–10 minutes to set before serving. Finish with a drizzle of pizza sauce, pepperonis, and fresh basil if desired.

This simple process guarantees a casserole that’s both visually appealing and bursting with flavor.
