Dump and Bake Pesto Chicken Penne

✉ Email this recipe

Some weeknights call for a dinner that comes together with little fuss and still feels like a treat. This dump and bake pesto chicken penne fits that bill. Uncooked penne, bite-size chicken, broth, cream, and basil pesto go into one baking dish, and the oven does most of the work. What comes out is creamy, pesto-coated pasta with tender chicken under a bubbling cheese topping.

This guide explains the reasoning behind the recipe and the small details that keep the pasta silky rather than dry. Use the recipe card for exact quantities, oven settings, and timing.

Why Uncooked Penne and Seasoned Chicken Work Together

Cooking the pasta right in the dish is what makes this recipe so easy. Penne's ridges and tube shape grab onto sauce, so each piece collects some of the pesto cream as it softens. The pasta absorbs the liquid as it bakes, so there is no pot to boil and no colander to drain.

Chicken breast is mild and takes seasoning well. Pat the pieces dry before tossing them with the salt, pepper, garlic powder, and Italian seasoning so the coating clings instead of sliding into the liquid. Evenly sized pieces help everything finish at the same time.

Building a Creamy Sauce That Coats Everything

The sauce is simple but essential. Low-sodium broth and heavy cream form a silky base, while basil pesto brings the bright, herbal flavor that defines the dish. Whisk them until smooth so the pesto spreads evenly rather than forming clumps that cling to only a few noodles.

Taste before baking. Pesto is naturally salty, and the low-sodium broth adds only a little more, so the sauce may already be seasoned well. Add a small pinch of kosher salt only if it tastes flat.

Checking Doneness and Finishing the Cheese

The most common mistake with baked pasta is leaving dry bits exposed. Any penne above the liquid stays firm while the rest turns soft, so stir thoroughly after pouring the sauce, lifting from the bottom of the dish until everything is submerged. Foil traps steam and helps the pasta cook evenly.

Before the cheese goes on, make sure the penne is tender and the chicken is fully cooked. An instant-read thermometer takes the guesswork out of the chicken. If either needs more time, cover the dish and keep baking.

Cheese belongs at the end. Mozzarella melts into a stretchy layer, Parmesan adds salty depth and browns at the edges, and open-air baking lets the top turn golden instead of steaming under the foil. Let the dish rest briefly so the sauce thickens, then garnish with basil if you like.

Frequently Asked Questions

Why does the penne need to be fully submerged?

Pasta above the liquid does not get enough moisture to soften, so it stays dry and firm while the rest of the dish turns tender. Stirring everything together before the dish goes under foil gives every piece a chance to cook through evenly.

Why is the cheese added after the covered bake?

Cheese added at the start would steam under the foil and lose its bubbly, golden top. Adding it once the penne is tender and the chicken is cooked lets the mozzarella and Parmesan melt and brown in open air, giving you the golden, bubbly topping.

Should I taste the sauce before it goes in the oven?

Yes, a quick taste is worth the moment. Pesto is naturally salty and the low-sodium broth adds only a little more, so the sauce may already be seasoned. Add a small pinch of kosher salt only if it tastes flat, then pour it over the pasta and chicken.
