Ingredients List

To create this hearty, crustless pizza casserole, gather the following ingredients. For each, consider the suggested substitutions if you have dietary preferences or need to tweak the macros:

– 1 lb ground Italian sausage (or ground turkey for a leaner option)
– 2 cups shredded mozzarella cheese (use dairy-free cheese if lactose intolerant)
– 1 cup marinara sauce (choose no-sugar-added or homemade to keep carbs low)
– 1 cup sliced pepperoni or your favorite cured meat (omit for paleo or whole30 compliance)
– 1 medium green bell pepper, diced (feel free to swap for red or yellow for color)
– 1/2 medium onion, finely chopped (substitute with shallots or omit for lower FODMAP)
– 3 large eggs (use flax eggs as vegan alternative)
– 1/4 cup grated Parmesan cheese
– 2 teaspoons Italian seasoning (or a mix of oregano, basil, and thyme)
– 1/2 teaspoon garlic powder
– Salt and pepper to taste
– Fresh basil leaves for garnish (optional)

Timing

Timing matters when making a dish this comforting. Here’s what you can expect:

– Prep time: 15 minutes — chop veggies and prepare ingredients while your oven preheats
– Cook time: 35 minutes — baking allows the cheese to melt perfectly and flavors to meld
– Total time: 50 minutes — perfect for a weekday dinner or weekend meal prep session

Imagine the enticing aroma of sausage and melted cheese filling your kitchen just 35 minutes from starting — it’s like a warm, tasty hug in casserole form.

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish or spray it with a non-stick baking spray. This prevents sticking and makes for easy cleanup.

Step 2: Cook the Sausage and Vegetables

In a large skillet over medium heat, cook the ground sausage until it’s browned and fully cooked. Use a spatula to break it apart into crumbles. Add the diced bell peppers and onions, sautéing until softened, about 5 minutes. Drain any excess fat to keep the casserole from feeling greasy.

Chef’s tip: If using turkey, add a splash of olive oil to the pan to prevent sticking.

Step 3: Mix the Eggs and Cheese

In a large bowl, whisk the eggs. Stir in the shredded mozzarella, grated Parmesan, Italian seasoning, garlic powder, salt, and pepper. This mixture will bind the casserole and add creaminess.

Step 4: Combine All Ingredients

Add the cooked sausage and veggies into the egg and cheese mixture. Pour in the marinara sauce and stir to combine all components evenly.

Step 5: Assemble and Layer

Spoon half of the mixture into the greased baking dish. Layer the sliced pepperoni evenly over the base layer, then top with the remaining mixture. This adds bursts of meaty flavor throughout.

Step 6: Bake Until Bubbly

Bake uncovered for 30-35 minutes until the casserole is set and the cheese on top is golden and bubbly. Let it rest for 5 minutes before slicing to help it firm up and slice neatly.

Chef’s tip: If you love extra crispy edges, pop the casserole under the broiler for 1-2 minutes—but watch carefully to avoid burning!

Common Mistakes to Avoid

Even simple recipes like this keto casserole can have pitfalls for home cooks:

– Don’t skip draining excess fat: It helps prevent a greasy texture.
– Avoid overbaking: Overcooked casserole becomes dry and rubbery — watch the timer closely.
– Be mindful of marinara sauce carbs: Using store-bought sauces with hidden sugars can spike net carbs.
– Under-seasoning: The sausage and cheese pair well with robust seasoning, so don’t be shy adding herbs and garlic powder.
– Layering pepperoni too early: Adding pepperoni in the middle helps retain its texture instead of turning soggy on top.

Storing Tips

Leftovers can be a lifesaver for busy weeknights. Keep these tips in mind:

– Cool the casserole completely before refrigerating to avoid condensation.
– Store in an airtight container in the fridge for up to 4 days.
– Reheat gently in a microwave or oven at 350°F (175°C) until warmed through.
– For longer storage, freeze portions in meal prep containers for up to 3 months.
– Thaw overnight in the fridge for best texture upon reheating.
