Instant Pot Creamy Chicken Pesto Pasta

This is that weeknight dinner that feels like you did something special-without actually doing much at all.
Creamy pesto pasta with juicy bites of chicken, made in one pot, with almost no hands-on time (a one-pot pressure-cooker pasta dish popular for quick weeknight meals)? That's a win - made in an Instant Pot pressure cooker that uses high-pressure steam to cook the chicken and pasta together for one-pot convenience.

Save for Later!

It's rich but not too heavy, herby but still balanced, and just the kind of meal that turns "we've got nothing in the fridge" into "why don't we make this more often?"
You don't need to pre-cook the pasta. You don't need a separate pan for the sauce.

The Instant Pot handles it all, and the cleanup is blissfully minimal.

We've made this after long workdays, last-minute dinners, and those nights where pasta is the only answer.
It's comforting, flexible, and always hits the spot.

What Goes in This Creamy Pesto Pasta

Everything here is straightforward and familiar, using classic pantry staples common in Italian-American weeknight cooking. That's what makes it so easy to pull off, even on a whim.

Save for Later!

• Chicken Breasts or Thighs - Either works, but thighs stay juicier. Cut them into chunks for even cooking.
• Pasta (penne or rotini) - Short pasta holds sauce better and cooks evenly under pressure, and it resists turning mushy when pressure-cooked.
• Chicken Broth - Adds savory depth and helps cook the pasta.
• Garlic and Onion - These aromatics bring the base flavor that rounds everything out.
• Jarred Basil Pesto - Use your favorite brand or homemade if you've got some.
• Heavy Cream - Stirred in at the end to make it extra smooth and rich; pair with creamy soups and comforting sides.
• Parmesan Cheese - Adds saltiness and a silky finish to the sauce.
• Salt, Pepper, Olive Oil - The essentials.

Want to level it up? A handful of spinach stirred in at the end adds color and freshness.

Pair this pasta with easy side dishes for chicken pesto pasta for balanced plates.

Step-by-Step: How to Make It in the Instant Pot

Once your ingredients are prepped, it's just a handful of steps between you and dinner.

• Start with the sauté - Set your Instant Pot to sauté. Add olive oil, chopped onion, and garlic. Cook for 2-3 minutes until softened and fragrant.
• Add the chicken - Toss in your chicken pieces, season with salt and pepper, and brown them lightly. Don't worry about cooking them through-they'll finish under pressure.
• Layer in pasta and broth - Add the dry pasta and pour the broth over top. Gently press the pasta down to make sure it's mostly submerged.
• Cook under pressure - Seal the lid and set to high pressure for 5 minutes. When done, do a quick release to prevent overcooking.
• Stir in the good stuff - Add pesto, heavy cream, and Parmesan cheese. Stir everything together until creamy and well combined. Let it sit for a minute or two to thicken.
• Taste and finish - Adjust seasoning if needed. Add more pesto or cheese if you want it richer.

That's it. One pot, one bowl, zero stress.

Easy Side Ideas to Round It Out

This pasta is rich and filling on its own, but a few light sides can balance out the plate, particularly bright, acidic salads like lemon-dressed greens that cut richness.Keep it simple, fresh, or crispy; consider leftover rotisserie chicken meal ideas for quick protein additions.

Side Dish	Why It Works
Garlic Bread	Crunchy contrast, and perfect for scooping up extra sauce
Mixed Green Salad	Adds a refreshing break between creamy bites
Roasted Cherry Tomatoes	Bright, sweet, and balances the richness
Sautéed Spinach	Earthy, quick to make, and looks great next to the pasta
Lemon-Parmesan Asparagus	Snappy, citrusy, and ties in well with the pesto
Caprese Salad	Fresh mozzarella and tomato add a cool counterpoint
Steamed Broccoli	Mild and reliable—always works with creamy sauces

It all works - bright, acidic sides like lemon-dressed salads help cut the richness and pair well with summer side dishes to steal the show.

How to Store and Reheat Creamy Pesto Pasta

This pasta keeps well, but you'll want to warm it gently to keep the sauce silky-not broken.

Storage Tips

• Cool completely before transferring to an airtight container.
• Store in the fridge for up to 4 days.
• Not freezer-friendly-cream sauces tend to separate when thawed.

Reheating Tips

• Microwave: Use 30-40 second intervals, stirring each time. Add a splash of cream or broth if it looks dry.
• Stovetop: Reheat on low with a bit of extra liquid, stirring frequently.
• Avoid high heat - It can make the sauce grainy or cause the cream to split.

Still creamy, still flavorful-just like fresh.

Creamy Chicken Pesto Pasta FAQ

Can I use a different protein?

Yes-cooked shredded chicken, rotisserie chicken, or even shrimp can work here. Just adjust cooking time if adding at the end.

Does it work with gluten-free pasta?

Yes, but watch the cook time-some gluten-free pastas break down faster - reduce high-pressure cook time by about 1-2 minutes compared to regular pasta. Stick to brands made for pressure cooking if possible.

Is homemade pesto okay?

Just use the same amount (about ¾ cup) and maybe ease up on the salt since homemade pesto can be more intense - homemade pesto often has brighter basil and pine nut flavors, and it also works well in pesto pasta variations for quick dinners.

Can I use milk instead of cream?

You can, but the sauce won't be as rich or smooth. Full-fat dairy works best here.

How do I make it vegetarian?

Skip the chicken and use veggie broth. Add mushrooms or spinach for texture and flavor.

For a tomato-free, sun-dried-tomato-forward option with spinach and creamy sauce, try Instant Pot Creamy Tuscan Chicken. If you prefer a cheese-forward, velvety sauce, the Instant Pot Chicken Alfredo Pasta delivers a classic Parmesan-cream finish.
