Description

This Italian-inspired chicken and spaghetti timballo has lots of pizza flavor thanks to pepperoni, mushrooms, black olives, and mozzarella cheese.

Ingredients

1 tablespoon olive oil
1 (16 ounce) package spaghetti
2 (24 ounce) jars marinara sauce
3 cups cooked chicken breast meat, diced
1 large onion, diced
1 (7 ounce) package of sliced pepperoni, diced
1 green pepper, diced
1 (5 ounce) can mushroom pieces, drained
1 (3 ounce) can sliced black olives, drained
3 cups shredded mozzarella cheese
1 tablespoon grated Parmesan cheese, or to taste

Directions

1 Preheat the oven to 350 degrees F (175 degrees C). Spread olive oil on the bottom of a cast iron skillet or large baking dish.
2 Bring a large pot of lightly salted water to a boil. Cook spaghetti in boiling water, stirring occasionally, until cooked through but firm to the bite, about 12 minutes; drain.
3 Stir spaghetti, marinara sauce, diced chicken, onion, pepperoni, green pepper, mushroom pieces, and black olives together in a large bowl; transfer into the prepared cast iron skillet. Top with a layer of mozzarella cheese and sprinkle with Parmesan cheese.
4 Bake in the preheated oven until casserole is bubbling, chicken is cooked through, and cheese topping is lightly browned, about 30 minutes.
