Instant Pot Chicken Pot Pie Filling Recipe: Creamy Vegetable-Rich Comfort in a Pot

This Instant Pot method delivers creamy, vegetable-packed chicken pot pie filling in a fraction of the traditional time. The pressure cooker tenderizes the chicken and infuses the vegetables with rich, savory flavor without sacrificing texture.

What results is a comfort food classic with perfectly cooked chicken, tender mixed vegetables, and a velvety sauce that clings to every bite. Ready to fill your pie crust or enjoy as a hearty stew.

Ingredients for Instant Pot Chicken Pot Pie Filling

Pantry staples plus a few fresh picks create this luscious, creamy filling packed with comfort.

The chicken is the foundation here. Boneless, skinless breasts stay tender under pressure, but thighs work too (just trim excess fat). I grab mine from Costco for bulk savings, but any supermarket brand is fine. Look for even thickness so pieces cook uniformly. The veggies—carrots, celery, and onion—are non-negotiable for that classic pot pie flavor. Fresh is best, but frozen works in a pinch for the peas.

No heavy cream? Whole milk plus a pat of butter gets you close to the same richness. Swap fresh thyme and rosemary if you’ve got them (use one-third the amount since dried is more concentrated). Vegetable broth instead of chicken works for a lighter touch. The frozen peas can be swapped for corn or green beans—whatever you’ve got in the freezer. Just don’t skip the butter in the sauce (trust me on the full-fat version).

This filling keeps beautifully—actually tastes better the next day. Store in an airtight container for up to 4 days in the fridge or freeze for 3 months. Reheat gently to keep that creamy texture intact (don’t boil or it might separate).

Step-by-Step Instructions for Chicken Pot Pie Filling

Here’s how I get that creamy, comforting filling every time with minimal effort.

Step 1: Sauté Aromatics and Chicken in the Instant Pot

Set your Instant Pot to Sauté mode and add 2 tablespoons of the unsalted butter. Once melted, add the finely diced yellow onion, minced garlic cloves, sliced carrots, and sliced celery stalks. Cook for 3-4 minutes until the onion becomes translucent.

Push the vegetables to the sides and add the 1.5 lb boneless, skinless chicken breasts (cut into bite-sized pieces) to the center. Sear for 2-3 minutes until the chicken turns white on all sides. This builds flavor that makes the dish taste like it simmered for hours.

Step 2: Pressure Cook the Chicken and Vegetables

Add the 2 cups chicken broth, 1 tsp dried thyme, 1 tsp dried rosemary, 1 tsp salt, and 0.5 tsp black pepper to the Instant Pot. Stir to combine, scraping up any browned bits from the bottom. Secure the lid and set the valve to Sealing.

Cook on High Pressure for 5 minutes. The chicken will finish cooking and the vegetables will soften perfectly. Once done, let the pressure release naturally for 5 minutes, then quick-release any remaining pressure.

Step 3: Shred Chicken and Thicken the Sauce

Remove the boneless, skinless chicken breasts and shred using two forks. Return the shredded chicken to the Instant Pot. Switch back to Sauté mode and add the remaining 0.5 cup unsalted butter (minus the 2 tablespoons used earlier).

Once melted, sprinkle in the 0.5 cup all-purpose flour and stir constantly for 1-2 minutes until the mixture thickens. This creates a roux that will turn your broth into a velvety sauce.

Step 4: Finish with Creamy Richness

Slowly pour in the 1 cup whole milk and 0.5 cup heavy cream, stirring continuously to prevent lumps. Add the 1 cup frozen green peas—no need to thaw first. Cook for another 2-3 minutes until the sauce reaches your desired consistency.

You’ll know it’s ready when the sauce coats the back of a spoon and the peas are heated through. The mixture should be thick but still pourable, perfect for filling a crust or serving over biscuits. Taste and adjust seasoning if needed.

Essential Equipment for instant pot chicken pot pie filling

Instant Pot Essentials

You need a 6-quart Instant Pot or larger for this recipe—I use my Duo Crisp model. The pressure cooking function is non-negotiable for achieving that fall-apart chicken texture in record time. 💡

Sauté Function

A good Instant Pot must have a reliable Sauté feature. This lets you brown the chicken and vegetables properly before pressure cooking, building those deep flavors that make this dish taste like it simmered all day.

Wooden Spoon

Use a wooden spoon for stirring and scraping the bottom. It won’t scratch your pot’s interior and helps deglaze all those flavorful browned bits. I keep mine right in my utensil crock next to the stove.

Shredding Tools

Two forks work perfectly for shredding the chicken, but I prefer my OXO Good Grips shredding claws. They make quick work of the chicken and save your hands from the heat. Plus, they’re dishwasher safe for easy cleanup.

Measuring Cups

Accurate measurements matter for the sauce consistency. I use my Pyrex glass measuring cups for the broth, milk, and cream. The clear markings make it easy to get the exact 2 cups broth and 1.5 cups dairy this recipe needs.

Ladle for Serving

A stainless steel ladle is perfect for serving this creamy filling. It handles the thick sauce better than a spoon and makes portioning into your pie crust or bowls effortless. I’ve had mine for years and it’s still going strong. ✨
