This oven baked 4-ingredient chicken tetrazzini is the kind of simple, comforting casserole that earns a permanent spot in a family recipe box. Recipes like this became popular in mid-century home kitchens because they stretched a little cooked chicken into a hearty meal, and I can absolutely see why it showed up at every reunion table. With just a handful of ingredients, it comes together fast, bakes up creamy and cozy, and feels like exactly the sort of dependable dinner a busy weeknight calls for.
Serve this rich pasta bake with a crisp green salad, steamed green beans, or simple roasted broccoli to balance the creamy sauce. If you are feeding a crowd, warm dinner rolls and a fruit salad fit the old-fashioned family-supper vibe perfectly, and a little extra grated Parmesan or black pepper at the table never hurts.
Oven Baked 4-Ingredient Chicken Tetrazzini
Servings: 6
Ingredients
8 ounces spaghetti, broken in half
2 cups cooked chicken, chopped or shredded
2 cans condensed cream of chicken soup
1 1/2 cups shredded cheddar cheese, divided
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch or similar rectangular glass casserole dish.
2. Cook the spaghetti in salted water until just al dente, then drain well.
3. In a large mixing bowl, stir together the cooked chicken, condensed cream of chicken soup, 1 cup of the shredded cheddar cheese, and the drained spaghetti until evenly coated.
4. Spread the mixture into the prepared casserole dish and sprinkle the remaining 1/2 cup cheddar evenly over the top.
5. Bake uncovered for 25 to 30 minutes, until hot and bubbly and the cheese on top is melted and lightly golden. Let it rest for 5 minutes before serving.
Variations & Tips
Add a crunchy topping: If you want a little more texture like many vintage casseroles had, scatter a light layer of buttered breadcrumbs or crushed buttery crackers over the cheese before baking.
Use leftover turkey: This recipe works beautifully with leftover roast turkey instead of chicken, especially around the holidays when you need an easy second-day dinner.
Make it creamier: If the mixture seems too thick before baking, stir in a splash of milk or chicken broth. That is especially helpful if your chicken is very lean or your noodles soaked up extra water.
Prep ahead: Assemble the casserole earlier in the day, cover, and refrigerate. When dinner rolls around, bake it straight from the fridge and add a few extra minutes to the cooking time.
Cheese swap: Cheddar gives this a cozy, old-school flavor, but mozzarella, Monterey Jack, or a cheddar-Parmesan blend also work well if that is what you have on hand.
