Creamy Pesto Chicken Bake — The Easy Weeknight Dinner You’ll Make on Repeat

Some nights you just need a meal that does all the heavy lifting. You know the kind — minimal effort, maximum flavor, and zero complaints from whoever is sitting at the table. That's exactly what this creamy pesto chicken bake delivers every single time.

I stumbled onto this recipe on one of those evenings where I had chicken, leftover pesto, and absolutely no patience for anything complicated. What came out of that oven stopped me in my tracks.

Golden, juicy chicken sitting on a bed of rigatoni, coated in the creamiest, most fragrant pesto sauce you'll ever taste. I've been making it on repeat ever since.

If you're a fan of pasta that actually feels like a hug, and chicken that doesn't taste like cardboard (you know what I'm talking about :)), this one's for you. Let's get into it.

Why you'll love this recipe

• It comes together in under 45 minutes, start to finish — no babysitting required
• The pesto cream sauce is rich, fragrant, and clings to every piece of rigatoni perfectly
• It's a one-dish wonder, which means less washing up after dinner
• The seared chicken adds a beautiful golden crust that holds up beautifully in the oven
• Fresh spinach sneaks in some nutrition without anyone noticing — or complaining
• It reheats like a dream, making it a solid meal prep option for the week

Ingredients with key notes

For the chicken:

• 1.5 lbs boneless, skinless chicken breasts or thighs, cut into bite-sized chunks
• 1 teaspoon garlic powder
• 1 teaspoon smoked paprika
• Salt and black pepper to taste
• 2 tablespoons olive oil

For the pasta and sauce:

• 12 oz rigatoni pasta
• 3 cloves garlic, minced
• 1 cup basil pesto (store-bought works great, homemade is even better)
• 1 cup heavy cream
• 1/2 cup chicken broth
• 2 cups fresh spinach
• 1/2 cup freshly grated Parmesan cheese
• 1/4 teaspoon red pepper flakes (optional but recommended)
• Fresh parsley or basil for garnish

Key notes:

• Chicken thighs vs breasts: Thighs are juicier and more forgiving in the oven. If you use breasts, don't overbake — they dry out fast.
• Pesto quality matters: IMO, this is not the place to go bargain shopping. A good quality pesto makes a huge difference in the final flavor. If you can find fresh pesto in the refrigerated section, grab it.
• Heavy cream: Don't swap this for half-and-half if you want that luscious, thick sauce. The fat content is what makes it cling beautifully to the pasta.
• Rigatoni: The tube shape holds the sauce inside each piece, which makes every bite ridiculously good. You can substitute with penne or ziti if needed.
• Parmesan: Always go freshly grated. Pre-shredded cheese has anti-caking agents that prevent it from melting smoothly into the sauce.

Step-by-step instructions

Step 1: Cook the pasta

Bring a large pot of salted water to a boil and cook the rigatoni until just shy of al dente — about 1-2 minutes less than the package instructions. It'll finish cooking in the oven, so you don't want it fully done here. Drain and set aside.

Step 2: Season and sear the chicken

Season your chicken pieces generously with garlic powder, smoked paprika, salt, and black pepper. Heat olive oil in a large oven-safe skillet over medium-high heat. Add the chicken in a single layer and sear for 3-4 minutes per side until golden brown. You're not cooking it through here — just building that beautiful crust. Remove and set aside.

Step 3: Build the pesto cream sauce

In the same skillet, reduce the heat to medium and add the minced garlic. Cook for about 30 seconds until fragrant — don't let it burn. Add the chicken broth and scrape up any brown bits from the bottom of the pan. Pour in the heavy cream and pesto, stirring to combine. Let it simmer for 2-3 minutes until it starts to thicken slightly.

Step 4: Bring it all together

Add the cooked rigatoni and fresh spinach into the sauce, tossing to coat everything evenly. The spinach will wilt quickly. Nestle the seared chicken pieces on top, then sprinkle with Parmesan and red pepper flakes.

Step 5: Bake

Transfer the skillet to your preheated oven at 375 degrees F. Bake uncovered for 18-20 minutes until the sauce is bubbling, the cheese is melted, and the chicken is cooked through. If you want a little golden color on top, switch to broil for the last 2 minutes — just keep an eye on it.

Step 6: Garnish and serve

Pull it out of the oven and let it rest for 5 minutes. Garnish with fresh parsley or basil and an extra grating of Parmesan. Then serve it up and watch it disappear.

Serving suggestions

• Serve with a side of crusty garlic bread to mop up every last drop of that pesto cream sauce
• A simple arugula salad with lemon vinaigrette balances out the richness of the dish beautifully
• Roasted cherry tomatoes on the side add a pop of color and a slightly sweet contrast
• A glass of chilled Pinot Grigio or Sauvignon Blanc pairs wonderfully with the herby pesto flavors
• For a heartier spread, serve alongside a Caesar salad and some roasted asparagus

Storage tips

Refrigerator: Store leftovers in an airtight container for up to 4 days. The flavors actually deepen overnight, so day-two leftovers are genuinely great.

Freezer: You can freeze this dish for up to 2 months. Let it cool completely, then transfer to a freezer-safe container. Thaw overnight in the fridge before reheating.

Reheating: Reheat on the stovetop over medium-low heat with a splash of chicken broth or cream to loosen the sauce. You can also microwave it in 90-second intervals, stirring in between. Avoid overheating — it can dry out the chicken and break the sauce.

Closing

This creamy pesto chicken bake is one of those recipes that quietly becomes a household staple. It's the kind of dish you bring out when you want to impress someone without spending your entire evening in the kitchen. And honestly? It's the kind of dish that reminds you cooking doesn't have to be complicated to be really, really good.
