This oven baked 4-ingredients chicken alfredo bake is exactly the kind of dinner my busy sister leans on when her kids have practice, homework, and everyone’s starving at the same time. It uses just a few supermarket shortcuts—jarred alfredo, rotisserie chicken, and shredded cheese—plus dry pasta, and everything bakes together in one disposable foil pan. No boiling the noodles first, no extra pots to wash. It comes together in seconds, bakes while you deal with the rest of life, and the leftovers reheat like a dream for lunches or another low-effort dinner.
Serve this chicken alfredo bake with a simple green salad (bagged salad mix totally counts) and some garlic bread or warm dinner rolls if you want to stretch the meal. Steamed broccoli or green beans are great on the side and can be tossed in a bit of olive oil, salt, and pepper for an easy veggie. For adults, a crisp white wine like Pinot Grigio or a sparkling water with lemon balances the richness. The leftovers pack perfectly into lunch containers with a handful of cherry tomatoes or carrot sticks on the side.

Oven-Baked 4-Ingredient Chicken Alfredo Bake

Ingredients
12 ounces uncooked short pasta (penne, rotini, or ziti)
3 cups shredded cooked chicken (such as rotisserie chicken, skin and bones removed)
2 (15-ounce) jars alfredo sauce
2 cups shredded mozzarella cheese, divided
Directions
Preheat your oven to 375°F (190°C). Place a disposable 9×13-inch aluminum foil baking pan on a sheet pan for extra support.
Add the uncooked pasta to the foil pan and spread it into an even layer.
In a large bowl or directly in the pan, combine the shredded cooked chicken and both jars of alfredo sauce. If mixing in a bowl, pour the mixture over the pasta. Stir everything together right in the foil pan until all the pasta is coated and the chicken is evenly distributed. Use the back of a spoon to press the mixture into an even layer.
Sprinkle 1 1/2 cups of the shredded mozzarella cheese evenly over the top of the pasta and chicken mixture, reserving the remaining 1/2 cup for later.
Cover the foil pan tightly with aluminum foil, making sure it’s well sealed so the pasta can steam and cook in the sauce.
Bake covered for 35–40 minutes, until the pasta is tender when you poke it with a fork in the center of the pan. If the pasta still has a bit of bite, re-cover and bake for another 5–10 minutes.
Once the pasta is tender, remove the foil cover. Sprinkle the remaining 1/2 cup mozzarella evenly over the top.
Return the pan to the oven, uncovered, and bake for 8–12 more minutes, or until the cheese on top is melted, bubbly, and golden brown in spots.
Let the chicken alfredo bake rest for 5–10 minutes before serving so it can set up slightly. Serve straight from the disposable foil pan, and refrigerate any leftovers in airtight containers for easy reheat-and-eat meals.
