This oven baked 4-ingredient sheet pan ranch chicken ziti is exactly the kind of recipe you lean on during a crazy week. My neighbor actually dropped a pan of this on our porch one Sunday when both my husband and I were buried in work and laundry, and it was such a lifesaver that it’s now on our regular Sunday rotation. It’s creamy, cozy, and tastes like you spent way more time on it than you actually did. Everything happens on one sheet pan and then bakes together in a casserole dish, so it’s practical for busy nights but still feels like a real home-cooked meal.
Serve this ranch chicken ziti hot with a simple green salad (bagged salad is totally fine) and some garlic bread or buttered rolls to soak up the extra sauce. A side of steamed broccoli or green beans also works really well with the creamy ranch flavor. If you like a little heat, add crushed red pepper at the table. It reheats nicely, so I often pack leftovers with some carrot sticks or sliced cucumbers for an easy lunch the next day.
Oven Baked 4-Ingredient Sheet Pan Ranch Chicken ZitiServings: 6
Ingredients
12 oz ziti pasta, uncooked
1 1/2 lbs boneless skinless chicken breasts
2 (16 oz) jars ranch Alfredo or ranch-flavored pasta sauce (about 4 cups total)
2 cups shredded mozzarella cheese
Directions
Preheat your oven to 400°F (200°C). Lightly grease a large rimmed sheet pan and a 9x13-inch baking dish with cooking spray or a thin layer of oil.
Place the chicken breasts on the sheet pan in a single layer. Season lightly with salt and pepper if you’d like (optional, not counted as an ingredient). Bake for 20–25 minutes, or until the chicken is cooked through and reaches 165°F in the thickest part.
While the chicken bakes, bring a large pot of salted water to a boil. Add the ziti and cook for 2–3 minutes less than the package directions for al dente (you want it quite firm since it will finish in the oven). Drain the pasta well and return it to the pot.
When the chicken is done, transfer it to a cutting board and let it rest for 5 minutes so the juices settle. Pour off any excess liquid from the sheet pan and discard.
Shred the rested chicken using two forks (or chop into small bite-size pieces if that’s easier for you). Add the shredded chicken to the pot with the drained ziti.
Pour both jars of ranch Alfredo or ranch-flavored pasta sauce over the pasta and chicken. Stir everything together until the ziti and chicken are evenly coated and the sauce is well distributed.
Transfer the creamy chicken ziti mixture into the prepared 9x13-inch baking dish, spreading it into an even layer. Sprinkle the shredded mozzarella cheese evenly over the top.
Cover the baking dish tightly with foil and bake at 400°F (200°C) for 15 minutes to heat everything through and let the flavors meld.
Remove the foil and bake for an additional 10–15 minutes, or until the cheese is fully melted, bubbly around the edges, and lightly golden in spots.
Let the baked ziti rest for 5–10 minutes before serving so it can set up a bit and the sauce thickens slightly. Scoop into bowls or onto plates and enjoy warm.
Variations & Tips
Use rotisserie chicken: To make this even faster, skip baking the chicken on the sheet pan and use about 4 cups of shredded rotisserie chicken. Toss it directly with the cooked ziti and sauce, then bake as directed. Extra veggies: If you want to sneak in some vegetables, stir in 1–2 cups of frozen peas, spinach, or broccoli florets with the pasta and sauce before baking. They’ll cook right in the casserole. Different pasta shapes: Penne, rigatoni, or shells all work well in place of ziti—just make sure to undercook by a couple minutes so they don’t get mushy in the oven. Cheese swaps: Mix in some shredded cheddar or Monterey Jack with the mozzarella for a slightly sharper flavor, or sprinkle grated Parmesan on top before baking for a saltier, more savory finish. Spice it up: Add a pinch of red pepper flakes or a few dashes of hot sauce into the sauce mixture if your family likes a little heat. Make-ahead tip: Assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. When baking from cold, add 10–15 extra minutes with the foil on so it heats through safely. Freezing: For longer storage, assemble in a freezer-safe dish, wrap well, and freeze up to 2 months. Thaw overnight in the fridge and bake until hot and bubbly. Food safety: Always cook chicken to an internal temperature of 165°F and use a food thermometer if you’re unsure. Don’t leave cooked chicken or the baked casserole at room temperature for more than 2 hours (or 1 hour if it’s very warm in your kitchen). Cool leftovers quickly, store them in shallow containers, and refrigerate within 2 hours; eat within 3–4 days or freeze. Reheat leftovers until steaming hot all the way through before serving.
