½ cup sliced turkey pepperoni

1 teaspoon olive oil, if needed

1 teaspoon Italian seasoning

½ teaspoon garlic powder

¼ teaspoon black pepper

Salt, to taste, if needed

Optional Pizza Toppings

½ cup sliced mushrooms

Fresh basil for garnish

🍳 Equipment Needed

9 × 13-inch baking dish

Large skillet

Large pot for pasta

Colander

Wooden spoon or spatula

Measuring cups and spoons

Meat thermometer

👩‍🍳 How to Make Weight Watchers Pizza Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9 × 13-inch baking dish with cooking spray.

Step 2: Cook the Pasta

Bring a large pot of water to a boil. Cook the pasta according to the package instructions, but drain it about 1–2 minutes before it reaches full tenderness.

The pasta will continue cooking in the oven, so slightly undercooking it helps prevent a mushy casserole.

Drain well and set aside.

Step 3: Brown the Ground Meat

Heat a large skillet over medium heat. Add the ground turkey or lean beef, breaking it into small crumbles as it cooks.

Cook until browned and fully cooked. Ground turkey and ground beef should reach 165°F (74°C) and 160°F (71°C), respectively.

Drain excess fat if necessary.

Step 4: Season the Meat

Stir in the Italian seasoning, garlic powder, black pepper, and a little salt if needed.

Add the marinara sauce and stir until the meat is evenly coated.

Let the mixture simmer gently for 2–3 minutes to bring the flavors together.

Step 5: Combine the Pasta and Sauce

Add the drained pasta to the skillet and stir until every piece is coated in the meat and tomato sauce.

If your skillet is too small, combine everything in a large mixing bowl instead.

Step 6: Assemble the Casserole

Transfer half of the pasta mixture to the prepared baking dish.

Sprinkle with half of the mozzarella and some of the turkey pepperoni. Add the remaining pasta mixture, then top with the remaining mozzarella and pepperoni.

If using mushrooms or bell peppers, distribute them evenly over the top.

Step 7: Bake Until Bubbly

Bake uncovered for 20–25 minutes, until the cheese is melted and the casserole is bubbling around the edges.

For a more golden cheese topping, broil for 1–2 minutes at the end, watching carefully to prevent burning.

Step 8: Rest and Serve

Let the casserole rest for 5 minutes before slicing or spooning into bowls.

Garnish with fresh basil or a little Parmesan if desired. Serve warm and enjoy all the classic pizza-inspired flavors in one satisfying meal.

💡 Tips for the Best Pizza Casserole

Choose Lean Ground Meat

Lean ground turkey or 93% lean beef provides plenty of flavor while helping you manage the overall fat content.

Measure the Cheese

Mozzarella adds much of the casserole’s richness. Measuring it helps keep portions consistent and makes WW Points easier to calculate.

Don’t Overcook the Pasta

Slightly undercooked pasta holds its shape better after baking.

Choose a Lower-Sugar Sauce

Compare marinara labels and select one with no added sugar when possible. Sodium and Points can vary between brands.

Let It Rest Before Serving

A five-minute rest helps the sauce settle and makes portioning easier.

❓ Frequently Asked Questions

Can I make this casserole ahead of time?

Yes! Assemble the casserole, cover, and refrigerate it before baking. For best texture, bake it within 24 hours and allow extra time if it goes into the oven cold.

Can I use regular pasta?

Absolutely. Regular pasta works well; whole-wheat pasta is simply another option. Points and nutrition will vary.

Can I make this without pepperoni?

Yes. Leave it out or replace it with extra vegetables. This will also change the nutrition and Points calculation.

Is this casserole kid-friendly?

Yes! Its familiar pizza flavors and cheesy topping make it a family-friendly dinner. You can keep the toppings simple or let everyone customize their portion.
