This oven baked 3-ingredients lazy Swiss ziti is the kind of practical weeknight casserole that earns a permanent place in a busy cook’s rotation. It leans on a short ingredient list for convenience, but still delivers a cozy, bubbling pan of pasta with creamy sauce and a browned Swiss cheese topping. If you like old-school Midwestern casseroles and simple baked pasta dishes, this one fits right in, especially on nights when you want dinner in the oven with almost no fuss.
Serve this rich, creamy ziti with a crisp green salad or simple steamed broccoli to balance the richness, and set out garlic bread or warm Italian bread to scoop up the extra sauce. If you want a heartier meal, roasted chicken, browned sausage, or meatballs on the side work especially well, and a glass of iced tea or a dry white wine makes a nice pairing.
Oven Baked 3-Ingredients Lazy Swiss Ziti
Servings: 6
Ingredients
12 ounces ziti pasta
Directions
1. Heat the oven to 375°F and lightly grease a 9-by-13-inch or similar rectangular glass baking dish.
2. Bring a large pot of salted water to a boil and cook the ziti until just shy of al dente according to the package directions. Drain well.
3. Return the drained pasta to the pot, add the white sauce, and stir until the ziti is evenly coated.
4. Spoon the sauced ziti into the prepared baking dish and spread it into an even layer. Top evenly with the Swiss cheese.
5. Bake uncovered for 20 to 25 minutes, until the cheese is melted, lightly golden, and the edges are bubbling. Let stand for 5 minutes before serving.
Variations & Tips
Add a protein: To make this more filling, stir in 2 cups of cooked shredded chicken, browned Italian sausage, or diced ham with the sauce before baking. Since Swiss cheese pairs especially well with ham and chicken, either option turns this into a more substantial casserole without adding much extra work.
Change the pasta: Penne, rigatoni, or most medium tube-shaped pastas work just fine here if that is what you have in the pantry. Just cook the pasta to slightly underdone so it finishes in the oven without becoming too soft.
Make it browner on top: If you like deeper color on the cheese, place the dish under the broiler for 1 to 2 minutes at the end of baking, watching closely. Swiss melts beautifully but can go from pale to too dark quickly, so this is one of those moments when it pays to stay by the oven.
Add seasoning carefully: Even though this is marketed as a 3-ingredient recipe, a little black pepper, garlic powder, or a pinch of nutmeg can improve a bland white sauce. Taste the sauce first if possible, because both jarred sauce and Swiss cheese can already bring plenty of salt.
Use the right dish size: A shallow glass baking dish helps the casserole heat evenly and gives you more surface area for that golden cheese topping. If you use a smaller, deeper dish, the center may need a few extra minutes in the oven.
