Chicken Pesto Pasta Instant Pot Recipe: Basil-Infused Creaminess in Minutes

This Instant Pot method redefines what’s possible for weeknight cooking. The pressure cooker transforms simple ingredients into a restaurant-quality meal with minimal hands-on time.

The beauty lies in its efficiency—pasta, chicken, and pesto cook together, absorbing flavors in ways traditional methods can’t match. No pre-cooking, no extra pots, just one-pot convenience.

What emerges is al dente pasta, tender chicken, and a creamy basil sauce that clings to every strand. The Instant Pot locks in freshness, making the pesto taste as vibrant as the day it was made.

Ready in 20 minutes, this dish proves that great flavor doesn’t require great effort. Every bite delivers the rich, herby depth you expect from pesto pasta—without the fuss.

Ingredients for Chicken Pesto Pasta Instant Pot

Restaurant-quality ingredients meet one-pot efficiency for weeknight cooking at its best.

The chicken quality is paramount. Boneless, skinless breasts from Whole Foods or Costco provide consistent tenderness. For the pesto, freshly made delivers superior vibrancy—though high-quality jarred brands like Barilla or Rao’s work in a pinch. The pasta should be bronze-cut for optimal sauce adhesion (look for De Cecco or Barilla brands).

Need to swap the chicken? Boneless thighs stay juicier but require an extra 2 minutes cook time. No heavy cream? Half-and-half or whole milk works with slightly less richness. For a lighter version, Greek yogurt can replace cream at a 1:1 ratio. The pesto can be swapped for sun-dried tomato or spinach pesto for variation.

Store uncooked chicken in the coldest part of your fridge for up to 2 days. The dish reheats well, maintaining texture for 3-4 days refrigerated. For longer storage, freeze in portions for up to 3 months—the pesto flavor holds remarkably well.

Step-by-Step Instructions for Chicken Pesto Pasta Instant Pot

Master the technique for creamy, restaurant-quality pasta with minimal effort and maximum flavor.

Step 1: Sauté Aromatics and Brown Chicken

Set the Instant Pot to Sauté mode and add the 1 tbsp Olive Oil. When hot, add the 0.5 whole Yellow Onion and cook for 3-4 minutes until translucent and just beginning to soften around the edges.

Add the 3 cloves Garlic Cloves and cook for 30 seconds until fragrant. Immediately add the 1 lb Boneless Skinless Chicken Breasts pieces, seasoning with 1 tsp Kosher Salt and 0.5 tsp Black Pepper. Sear for 2-3 minutes until the chicken turns opaque on the outside—it doesn’t need to cook through at this stage.

Step 2: Pressure Cook Pasta and Chicken

Pour in the 2.5 cups Chicken Broth and stir, scraping the bottom of the pot to deglaze and prevent burning. Add the 8 oz Penne Pasta, stirring to combine and ensuring the pasta is mostly submerged in the liquid.

Secure the lid, set the valve to Sealing, and cook on High Pressure for 5 minutes. The Instant Pot will take about 10 minutes to come to pressure before the timer begins. Once cooking completes, allow a 5-minute natural release before carefully switching the valve to Venting for a quick release.

Step 3: Stir in Pesto and Cream for Silkiness

Open the lid and stir in the 1 cup Basil Pesto and 0.5 cup Heavy Cream. The residual heat will warm these ingredients through, creating a velvety sauce that coats the pasta and chicken evenly.

If the mixture appears too thick, add a splash of additional chicken broth or water, 1-2 tablespoons at a time, until it reaches your desired consistency. The sauce should cling to the pasta but still flow smoothly.

Step 4: Finish with Cheese and Fresh Basil

Sprinkle in the 0.5 cup Parmesan Cheese and stir until fully melted and incorporated. Taste and adjust seasoning, adding a pinch of 0.25 tsp Red Pepper Flakes if you prefer a subtle heat.

Finally, stir in the 0.25 cup Fresh Basil Leaves and let the dish sit for 2-3 minutes to allow the flavors to meld. The basil should wilt slightly but retain its bright green color and fresh aroma.

Pro Cooking Tips for Perfect Results

Prevent Pasta Overcooking

Cut the 8 oz Penne Pasta in half before adding to the Instant Pot. This ensures even cooking and prevents mushy texture. I also recommend using 1 minute less pressure time if you prefer firmer pasta. 💡

Deglaze Thoroughly

After browning the chicken, pour ¼ cup Chicken Broth into the pot and scrape the bottom with a wooden spoon. This prevents the Burn notice and ensures all flavorful bits are incorporated into the sauce.

Layer Ingredients Strategically

Place the 1 lb Boneless Skinless Chicken Breasts on top of the pasta rather than mixing it in. This keeps the chicken from sticking to the bottom and allows steam to circulate evenly during pressure cooking.

Pesto Timing Matters

Stir in the 1 cup Basil Pesto and 0.5 cup Heavy Cream only after pressure cooking. Adding pesto too early can make it bitter. The residual heat is perfect for melting everything together without curdling the cream.

Cheese Integration

Sprinkle the 0.5 cup Parmesan Cheese gradually while stirring. This creates a smooth, creamy texture rather than clumpy cheese. I prefer freshly grated Parmigiano-Reggiano for the best melt and flavor. 🧀

Rest Before Serving

Let the dish sit for 5 minutes after adding the 0.25 cup Fresh Basil Leaves. This allows the flavors to meld and the sauce to thicken slightly. The basil will wilt just enough to release its aroma without losing color.
