Pesto Chicken Pasta Bake

There’s something about a bubbling, cheesy bake that feels like a warm hug on a weeknight. This Pesto Chicken Pasta Bake is one of those recipes: fast, forgiving, and full of bright herb flavor from pesto, creamy richness from heavy cream, and satisfying bites of shredded chicken, peas, and sun-dried tomatoes. It’s perfect for feeding a family or for packing lunches for the week.

Why this Pesto Chicken Pasta Bake works

This bake balances simple pantry staples with bold tastes. Prepared pesto brings basil, garlic, and Parmesan-forward flavor without any chopping. Heavy cream (or milk/half and half) adds silkiness that helps the pesto coat every noodle. Rotisserie-style shredded chicken gives protein and a little savory depth, while frozen peas add a pop of color and sweetness. Sun-dried tomatoes in oil introduce tang and a concentrated tomato note that pairs beautifully with the cheese melt on top. It’s an effortless dinner that looks and tastes like you spent longer in the kitchen than you actually did.

Ingredients

• ▢16ozpasta, any shape
• ▢8ozpesto, prepared (about 1 cup)
• ▢1/2cupheavy cream, milk or half and half will also work
• ▢2cupsshredded chicken, (or chopped) Rotisserie works well
• ▢12ouncesfrozen peas
• ▢1jarjulienne cut sun dried tomatoes in oil, 8.5 ounce jar, drained
• ▢1cupshredded mozzarella cheese, or Italian blend

Prep and timing

Active time: about 20 minutes. Total time: roughly 40–45 minutes, including pasta cooking and baking. This recipe is great when you want dinner ready quickly without a lot of babysitting.

Equipment

• Large pot for boiling pasta
• Colander
• Mixing bowl or the empty pasta pot
• 9×13-inch (or similar) baking dish
• Spatula or large spoon

Step-by-step instructions

1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set it aside.
2. Bring a large pot of salted water to a boil. Add the 16ozpasta and cook according to package directions until just al dente. Drain the pasta and return it to the pot or a large mixing bowl.
3. While the pasta cooks, measure and prepare the other ingredients: have 8ozpesto ready, measure 1/2cupheavy cream (or milk/half and half), shred or chop 2cupsshredded chicken, thaw 12ouncesfrozen peas if needed, and drain the jar of julienne cut sun dried tomatoes in oil (8.5 ounce jar).
4. Add the 8ozpesto and 1/2cupheavy cream to the drained hot pasta. Stir thoroughly so the pesto and cream evenly coat the noodles. The heat from the pasta will help loosen the pesto and create a silky sauce.
5. Fold in the 2cupsshredded chicken, 12ouncesfrozen peas, and the drained sun dried tomatoes. Mix until the chicken and vegetables are evenly distributed through the pasta.
6. Transfer the combined pasta mixture into the prepared baking dish and spread it into an even layer.
7. Sprinkle 1cupshredded mozzarella cheese (or Italian blend) evenly over the top of the pasta mixture.
8. Bake in the preheated oven for 15–20 minutes, or until the cheese is melted and the edges are lightly browned. If you like a more browned top, place under the broiler for 1–2 minutes—watch closely to prevent burning.
9. Remove the dish from the oven and let it rest for 5 minutes before serving. This helps the sauce set slightly so servings hold together better.
10. Scoop and serve warm. Leftovers keep well in the refrigerator for 3–4 days and reheat nicely in the oven or microwave.

Taste and serving suggestions

Serve this Pesto Chicken Pasta Bake with a crisp green salad and a squeeze of lemon if you want a bright contrast. A few extra torn basil leaves or a light drizzle of olive oil before serving adds fresh aroma. For a heartier meal, pair with garlic bread or roasted vegetables.

Notes and substitutions

• If you prefer, use milk or half and half in place of heavy cream—either works and changes the richness slightly.
• Any pasta shape will work; short shapes like penne, rotini, or shells hold the pesto sauce well.
• Use leftover cooked chicken or store-bought rotisserie-style shredded chicken for speed. Keep the 2cups measurement for the right balance.
• If your jar of sun dried tomatoes is packed in oil, drain them well to keep the bake from becoming too oily.
• Feel free to mix in a handful of spinach or kale for extra greens—tuck them into the warm pasta so they wilt gently.

Make-ahead and storage

Assemble the dish through step 7 and refrigerate (covered) for up to 24 hours. Add the shredded cheese just before baking, then bake as directed. For freezing, bake first, cool, then wrap tightly and freeze for up to 2 months. Reheat from frozen in a 350°F (175°C) oven until warmed through, about 45–60 minutes.
