🥘 Ingredient Notes
Simple, everyday ingredients make this casserole easy to assemble:
- Egg noodles (smart pasta) – broad egg noodles work well; I use no-yolk broad noodles.
- Red pasta sauce (marinara) – any jarred sauce you like.
- Cream of chicken soup (low-fat) – the canned soup adds creaminess; low-fat keeps it lighter.
- Cheddar and Parmesan – light versions help reduce calories and fat.
- Extra-lean ground beef – gives the casserole a meaty texture while keeping it lean.
- Turkey pepperoni – a lower-fat pepperoni option; use sliced or stick-style, chopped.
📖 Variations & Substitutions
- Noodles – swap for penne, whole wheat pasta, smart pasta, or spiralized zucchini to cut carbs.
- Meat – use lean ground turkey, ground chicken, or crumbled tofu instead of beef.
- Pepperoni – use sliced turkey pepperoni or your preferred lean pepperoni.
- Cheese – part-skim mozzarella is a good substitute for cheddar.
- Peppers – any color bell pepper is fine: red, orange, yellow, or green.
- Toppings – add Italian turkey or chicken sausage, Italian seasoning, or other favorite pizza toppings.
- Cream soup – make a homemade “cream of” soup to control sodium and ingredients.
- Spicy – add red pepper flakes or jalapeños for heat.
🔪 How to Make Healthy Pizza Casserole
Prep: Preheat oven to 350°F (176°C). Cook noodles according to package directions, drain, and set aside.
Spray a large skillet with non-stick spray. Cook mushrooms, onion, and bell pepper over medium heat, covered, for about 5 minutes until softened.
Add the extra-lean ground beef to the skillet and cook until browned.
Once the beef is browned, combine it with the cooked vegetables.
Stir in pasta sauce, cream of chicken soup, ¾ cup of cheddar cheese, chopped turkey pepperoni, and most of the sliced olives (reserve a few for garnish). Add the drained noodles and mix until well combined.
Spoon the mixture into a prepared casserole dish and smooth the top. Bake until hot and bubbly, about 35 minutes.
Remove from the oven, sprinkle the remaining cheddar over the top, and return to the oven for about 5 minutes until the cheese melts. Garnish with grated Parmesan and the reserved olives, then serve hot.
Expert Recipe Tips
- Undercook the pasta slightly: Boil the noodles 1–2 minutes less than the package suggests so they hold up during baking.
- Layer the cheese: Tuck some cheese between layers for a gooey interior rather than mixing it all in.
- Increase fiber: Replace half the pasta with spiralized zucchini or use whole wheat noodles.
- Add more veggies: Fold in spinach, kale, or grated carrots for extra nutrients.
- Reduce sodium: Use low-sodium sauce and make homemade cream-of-chicken to control salt.
- Use leaner meat: Ground turkey, chicken, or tofu are good lower-fat alternatives.
- Greek yogurt swap: Substitute half the cream soup with plain Greek yogurt for added protein and creaminess.
- Let it rest: Allow the casserole to sit 5–10 minutes after baking so it sets and slices more cleanly.
- Crispy topping: Broil for 2–3 minutes at the end for a golden, crispy cheese crust.
🥗 What to Serve With This Casserole
A light green salad or breadsticks complement the casserole nicely. For a lighter side, try cloud bread or a fresh spinach salad.

Defrost overnight in the refrigerator. Preheat oven to 350°F (175°C). Remove any plastic wrap, cover tightly with foil, and bake 20–30 minutes until heated through (internal temperature 165°F / 75°C). Remove foil and broil for a minute or two for a crisp top, if desired.
