Ingredients
3 pounds ground chicken (or ground turkey, Italian sausage, or any combination)
1 (24 oz) jar Rao’s Marinara Sauce or your favorite sugar-free pasta sauce
4 cups shredded Italian cheese blend, divided
1 (6 oz) package mini pepperoni
1 teaspoon Italian seasoning
1 teaspoon garlic powder
1 teaspoon onion powder
½ teaspoon crushed red pepper flakes (optional)
Salt and black pepper, to taste
Optional Pizza Toppings
Sliced pepperoncini peppers
Green bell peppers, diced
Black olives
Mushrooms
Onions (use sparingly for keto)
Cooked bacon
Jalapeños
Fresh basil
Parmesan cheese
Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch casserole dish with cooking spray or butter.
Step 2: Cook the Meat
Heat a large skillet over medium-high heat.
Add the ground chicken (or your preferred meat) and cook until fully browned, breaking it into crumbles as it cooks.
Drain any excess grease if necessary.
Season with Italian seasoning, garlic powder, onion powder, salt, pepper, and crushed red pepper flakes.
Step 3: Assemble the Casserole
In a large bowl, combine:
Cooked meat
Marinara sauce
Half of the shredded Italian cheese (2 cups)
Half of the mini pepperoni
Mix until everything is evenly coated.
Transfer the mixture into the prepared casserole dish and spread evenly.
Step 4: Add the Toppings
Sprinkle the remaining 2 cups of shredded cheese evenly over the top.
Add the remaining pepperoni and your favorite keto pizza toppings.
Finish with a little Parmesan cheese and extra Italian seasoning if desired.
Step 5: Bake
Bake uncovered for 30–45 minutes, or until the cheese is melted, bubbly, and lightly golden.
For an extra crispy cheese topping, broil for 2–3 minutes at the end of baking.
Step 6: Serve
Let the casserole rest for 5–10 minutes before slicing.
Serve with a fresh Caesar salad, roasted broccoli, zucchini noodles, or garlic butter green beans.
Tips
Ground Italian sausage adds incredible pizza flavor.
Use whole-milk mozzarella for the best cheese pull.
Add cooked mushrooms or spinach for extra vegetables.
Store leftovers in the refrigerator for up to 4 days.
Freeze individual portions for quick keto lunches.
