Ingredients for Chicken Pesto Instant Pot

Restaurant-quality ingredients for effortless pressure cooker perfection in minutes.

The chicken quality is paramount for this dish. Boneless, skinless breasts from Whole Foods or Costco ensure consistent tenderness under pressure. Select pieces of uniform thickness (or pound them yourself) to guarantee even cooking. For the basil, fresh, vibrant leaves are non-negotiable—avoid pre-packaged herbs with signs of wilting or browning.

Pine nuts can be substituted with walnuts or cashews at half the amount if budget is a concern. No pine nuts at all? Sunflower seeds work surprisingly well. For the Parmesan, Parmigiano-Reggiano is ideal, but Pecorino Romano offers a sharper alternative. The chicken broth can be replaced with vegetable broth for a lighter profile.

Store fresh basil wrapped in damp paper towels for up to 1 week. The pesto sauce keeps for 5 days refrigerated in an airtight container, or freeze in ice cube trays for up to 3 months. Chicken cooks best immediately but can be refrigerated raw for 2 days prior to cooking.

Step-by-Step Instructions for Chicken Pesto Instant Pot

This method delivers tender chicken and vibrant pesto sauce with minimal active time.

Step 1: Prepare the Chicken and Pesto Ingredients

Pat the 1.5 lb boneless skinless chicken breasts dry with paper towels and season both sides with 1 tsp kosher salt and 0.5 tsp freshly ground black pepper. I pound the breasts to an even thickness beforehand—this ensures uniform cooking in the pressure cooker.

In the Instant Pot, combine the 2 cups fresh basil leaves, 0.33 cup pine nuts, 4 cloves garlic cloves, 0.75 cup parmesan cheese, 1 tbsp lemon juice, 1 tsp dijon mustard, and 0.25 tsp red pepper flakes. Pulse with an immersion blender or food processor until finely chopped, then drizzle in 0.5 cup extra-virgin olive oil while blending to create a smooth pesto.

Step 2: Sear the Chicken Directly in the Instant Pot

Set the Instant Pot to Sauté mode on Normal heat. Add 1 tablespoon of the prepared pesto (reserve the rest) and swirl to coat the bottom. When the pesto begins to sizzle, add the seasoned chicken breasts in a single layer. Sear undisturbed for 3-4 minutes until the underside develops a golden-brown crust.

Flip the chicken and sear the second side for another 2-3 minutes. The goal here is color and flavor development, not full cooking. Remove the chicken to a plate and set aside.

Step 3: Pressure Cook with Broth and Cream

Pour 0.5 cup chicken broth and 0.25 cup heavy cream into the Instant Pot, using a wooden spoon to scrape up any browned bits from the bottom. This deglazing step prevents the “Burn” notice and incorporates maximum flavor. Return the chicken to the pot, along with any accumulated juices.

Secure the lid, set the valve to Sealing, and cook on High Pressure for 8 minutes. The chicken will be perfectly tender when done. Allow a 5-minute natural release, then quick-release any remaining pressure.

Step 4: Finish with Pesto and Serve

Carefully remove the chicken to a cutting board. Switch the Instant Pot back to Sauté mode and stir in the remaining pesto. Simmer for 2-3 minutes until the sauce thickens slightly and the flavors meld. Taste and adjust seasoning if needed.

Slice the chicken against the grain into ½-inch thick pieces and return them to the pot. Toss gently to coat in the creamy pesto sauce. Serve immediately over pasta, rice, or with crusty bread to soak up every last bit of sauce. The chicken should be juicy and the sauce vibrant green with a rich, herby aroma.

Flavor Customization for This chicken pesto instant pot

Herb Variations

Swap half the basil for fresh spinach or arugula for a milder, slightly bitter twist. I’ve found 1 cup of each maintains the vibrant color while adding depth. For a Mediterranean flair, try ½ cup fresh mint with the basil. 🌿

Nut Swaps

Replace pine nuts with walnuts or cashews for a budget-friendly option. Use the same ⅓ cup amount but toast them in a dry pan for 2-3 minutes first. For nut-free versions, sunflower seeds work surprisingly well with the same quantity.

Cheese Alternatives

Pecorino Romano adds a sharper, saltier kick than Parmesan. Use ½ cup and reduce added salt. For a creamy twist, substitute ½ cup grated Asiago. Vegans can use nutritional yeast at ⅔ cup for a cheesy flavor without dairy.

Spice Adjustments

Increase heat with an extra ¼ tsp red pepper flakes or add ½ tsp smoked paprika for depth. For a citrus boost, add 1 tsp lemon zest to the pesto. I love a pinch of nutmeg for warmth in cooler months. ✨

Creamy Variations

For a lighter sauce, replace heavy cream with ½ cup Greek yogurt or coconut milk. Stir in after pressure cooking to prevent curdling. For extra richness, add 2 tbsp cream cheese while blending the pesto.

Protein Swaps

This method works beautifully with chicken thighs—use 1.5 lbs boneless and reduce cooking time to 6 minutes. For a vegetarian option, try chickpeas (2 cans, drained) with the same cooking time and liquid amounts.
