Cheesy Smoked Sausage Casserole

Step 1
Preheat the oven to 400 degrees F (200 degrees C). Grease a 9×13-inch baking dish with butter and 1 teaspoon oil.

Step 2
Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally, until cooked through but firm to the bite, about 8 minutes. Drain.

Step 3
Stir sausage, tomatoes and reserved juice, onion, Cheddar cheese, Monterey Jack cheese, remaining 2 teaspoons olive oil, parsley, onion powder, garlic powder, salt, and pepper together in a large bowl. Add elbow macaroni and stir. Pour macaroni mixture into the prepared baking dish, sprinkle with American cheese, and cover with aluminum foil.

Step 4
Bake in the preheated oven for 30 minutes. Remove aluminum foil from the baking dish, increase heat to 425 degrees F (220 degrees C), and bake until sauce is bubbly, and top is golden brown, about 15 minutes. Cool for 15 minutes before serving.
