This 5-ingredient oven ziti is the kind of weeknight recipe I lean on when the day has gotten away from me but I still want a real, comforting meal on the table. The magic here is that you literally dump dry ziti into a glass casserole dish, add four simple pantry staples, and let the oven do the work. No boiling pasta, no elaborate sauce—just a very practical, very satisfying baked pasta that tastes like you fussed. Baked pasta dishes like this are loosely inspired by Italian-American baked ziti, but streamlined for modern home kitchens where convenience and flavor both matter.
Serve this oven ziti straight from the glass casserole dish with a big green salad—think romaine or mixed greens with a sharp vinaigrette—to cut through the richness. Garlic bread or warm crusty rolls are classic companions and help scoop up the extra sauce and cheese. A simple roasted vegetable, such as broccoli or green beans, rounds out the plate nicely. If you enjoy wine, a light red like Chianti or a medium-bodied zinfandel pairs well with the tomato and cheese.
5-Ingredient Oven Ziti
Servings: 6
Ingredients
12 ounces dry ziti pasta
3 cups jarred marinara sauce
3 cups water
2 cups shredded mozzarella cheese, divided
1/2 cup grated Parmesan cheese
Directions
Preheat your oven to 400°F (200°C). Have a 9x13-inch glass casserole dish ready; there is no need to grease it.
Pour the dry ziti pasta evenly into the bottom of the glass casserole dish, spreading it into an even layer so it cooks uniformly.
In a large bowl or measuring pitcher, whisk together the jarred marinara sauce and the water until well combined. This thinned sauce is what will hydrate and cook the pasta in the oven.
Pour the marinara-and-water mixture evenly over the dry ziti in the glass dish, nudging the pasta gently with a spoon to make sure all the pieces are submerged in liquid. It will look quite soupy—that is exactly what you want.
Sprinkle 1 cup of the shredded mozzarella evenly over the top of the sauced pasta. This first layer melts into the dish as it bakes, helping everything hold together.
Cover the glass casserole dish tightly with aluminum foil, crimping the edges to seal in steam. Transfer to the preheated oven and bake for 35 to 40 minutes, until the pasta is just tender when you poke a piece with a fork.
Carefully remove the dish from the oven and take off the foil, watching for escaping steam. The pasta should be mostly cooked and the sauce thickened around the edges.
Sprinkle the remaining 1 cup shredded mozzarella and all of the grated Parmesan evenly over the top of the hot pasta.
Return the uncovered dish to the oven and bake for another 10 to 15 minutes, until the cheese is melted, bubbly, and lightly golden in spots.
Let the baked ziti rest on the counter for 10 minutes before serving. This brief rest allows the sauce to settle and the pasta to firm up slightly, making it easier to scoop clean portions from the glass dish.
Variations & Tips
You can adapt this basic formula in several ways while keeping the dump-and-bake spirit. For extra protein, stir 1 to 1 1/2 cups of cooked Italian sausage or diced cooked chicken into the dry pasta before adding the liquid; just be sure any meat is fully cooked and cooled slightly before it goes into the dish. If you have ricotta on hand and do not mind a sixth ingredient, dollop 1 cup of ricotta over the top before the final cheese layer for a more traditional baked ziti texture. To boost flavor without changing the method, add 1 teaspoon of dried Italian seasoning or dried oregano to the marinara-and-water mixture, or scatter a pinch of red pepper flakes over the top before baking for gentle heat. Whole-wheat ziti can be used, but it may need an extra 1/4 cup water and 5 to 10 more minutes under foil; check for tenderness before adding the final cheese. For food safety, keep any meat additions refrigerated until just before assembling, and never add raw ground meat directly to this dish, as the bake time and moisture level are not calibrated for safely cooking raw proteins. Leftover baked ziti should be cooled, covered, and refrigerated within 2 hours of baking and eaten within 3 to 4 days; reheat portions until they are steaming hot in the center (165°F/74°C) before serving. If baking in a smaller or deeper dish, watch the timing closely, as deeper layers may need a few extra minutes under foil to fully cook the pasta.
