This oven baked creamy summer zucchini ziti is the kind of easy casserole that earns instant recipe requests because it turns a short ingredient list into something cozy, satisfying, and perfect for warm-weather gatherings. Zucchini softens and roasts right into the creamy pasta, while a shower of Parmesan creates that golden top everyone digs into first. It is a smart way to use up peak-season zucchini and a reliable dish to carry to a cookout, potluck, or relaxed family dinner.
Serve this ziti with a crisp green salad, sliced tomatoes, grilled chicken, or simple burgers if you are feeding a crowd outdoors. It also pairs nicely with garlic bread, fresh fruit, or roasted corn, and because the pasta is rich and creamy, bright sides with a little acidity help balance the meal beautifully.
Oven Baked 4-Ingredients Creamy Summer Zucchini Ziti
Servings: 6
Ingredients
12 ounces ziti pasta
3 medium zucchini, sliced into 1/4-inch rounds
15 ounces Alfredo sauce
1 1/2 cups grated Parmesan cheese, divided
Directions
1. Heat the oven to 400°F and lightly grease a rectangular baking dish. Bring a large pot of salted water to a boil and cook the ziti until just shy of al dente, then drain.
2. In a large bowl, combine the drained ziti, sliced zucchini, Alfredo sauce, and 1 cup of the Parmesan cheese. Toss until the pasta and zucchini are evenly coated.
3. Spread the mixture into the prepared baking dish and sprinkle the remaining 1/2 cup Parmesan evenly over the top.
4. Bake for 25 to 30 minutes, until the zucchini is tender, the sauce is bubbling around the edges, and the top is golden brown. Let it rest for 5 to 10 minutes before serving.
Variations & Tips
Add a little freshness: If you have extra ingredients on hand, a handful of chopped basil or parsley scattered over the top after baking adds color and makes the creamy pasta taste even more summery.
Make it heartier: For a more filling version, stir in shredded rotisserie chicken or cooked Italian sausage. This works especially well if you are serving the casserole as the main dish for a larger dinner.
Watch the zucchini texture: Slice the zucchini evenly and avoid overbaking, since zucchini releases moisture as it cooks. Keeping the rounds around 1/4 inch thick helps them turn tender without becoming mushy.
Choose your sauce carefully: Since there are only four ingredients, the flavor of the Alfredo sauce matters. Use one you already know you like, or a thicker style sauce so the casserole stays creamy instead of watery.
Prep ahead: You can assemble the dish several hours in advance and refrigerate it covered. When ready to bake, let it sit at room temperature for about 20 minutes first so it heats more evenly in the oven.
