Ingredients
1 jar RAO’s marinara (low-sugar marinara preferred)
3 cups shredded mozzarella cheese
1 lb ground Italian sausage (or meat combo of choice)
1 green pepper, chopped
Mushrooms, sliced
Onions, chopped
Why These Ingredients Work
RAO’s Marinara
Low in sugar and rich in flavor. Provides the pizza sauce base without excess carbs.
Italian Sausage
Brings bold seasoning and fat, which keeps the bake moist and flavorful.
Mozzarella
Creates that signature pizza cheese pull and golden bubbly top.
Green Pepper, Mushrooms, Onions
Classic pizza toppings that add texture, moisture, and flavor balance.
Step-by-Step Instructions
Step 1: Preheat Oven
Preheat oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
Step 2: Cook the Sausage
In a skillet over medium heat, cook the Italian sausage until fully browned.
Break it apart as it cooks.
Drain excess grease if necessary.
Step 3: Sauté the Vegetables
In the same skillet, lightly sauté the onions, mushrooms, and green peppers for 3–5 minutes until slightly softened.
This prevents excess moisture in the bake.
Step 4: Layer the Bake
- Spread half of the marinara sauce in the baking dish.
- Add the cooked sausage evenly.
- Layer sautéed vegetables on top.
- Pour remaining marinara over everything.
- Top generously with 3 cups shredded mozzarella.
Step 5: Bake
Bake uncovered for 25–30 minutes until:
• Cheese is fully melted
• Edges are bubbly
• Top begins to turn golden
Optional: Broil 1–2 minutes for extra browning.
Step 6: Rest & Serve
Let rest for 5–10 minutes before slicing.
This helps the casserole set and prevents excess liquid.
