Instructions

Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish with oil or nonstick spray.
Bring a large pot of salted water to a rolling boil. Add the spaghetti and cook 1–2 minutes less than the package recommends (about 8–9 minutes) so it’s just al dente. Drain and set aside.
Warm 2 tablespoons olive oil in a skillet over medium heat. Add the chopped onion and bell pepper. Sauté 4–6 minutes until softened and slightly translucent. Season lightly with salt and pepper.
In a large mixing bowl, combine the drained spaghetti, shredded chicken, chicken broth, cream of mushroom soup, diced tomatoes with green chiles, sautéed vegetables, garlic powder, and several grinds of black pepper. Stir until everything is evenly coated and saucy. Taste and adjust salt/pepper.
Transfer the mixture to the prepared baking dish and spread into an even layer. Sprinkle the grated cheddar and mozzarella evenly over the top.
Bake about 25 minutes, until cheese is bubbly and edges are bubbling. For a deeper golden top, broil on high 1–3 minutes — watch closely so it doesn’t burn.
Remove from the oven and rest 5 minutes before serving to let the casserole set slightly.

Notes

Shredded rotisserie chicken saves time. If using leftover chicken with low moisture, you may need a splash more broth. For vegetarians, swap chicken for canned white beans or extra mushrooms.
