Instant Pot Frozen Chicken Breasts: Tender, Juicy in 15 Minutes

Learn a simple, time-saving way to cook frozen chicken breasts in your Instant Pot pressure cooker and use the cooked chicken in all your favorite recipes. This method eliminates the need to remember to defrost chicken ahead of time and makes weeknight dinners much easier.

For busy evenings when you forgot to thaw chicken, cooking directly from frozen in the Instant Pot is a lifesaver. No more last-minute changes or takeout—this straightforward Instant Pot method delivers reliably cooked chicken every time.

I prefer fresh chicken when I can, but when breasts are on sale I buy extras and freeze them. Cooking from frozen in the pressure cooker removes the hassle of thawing and keeps the meat ready for whatever recipe you need.

This guide covers how to cook plain frozen chicken breasts in the Instant Pot. The cooked results are versatile: shred, slice, or dice the chicken and add it to tacos, salads, pasta dishes, casseroles, or soups.

How to Cook Frozen Chicken Breasts in the Instant Pot

Start by placing the frozen chicken breasts directly into the Instant Pot inner pot. A trivet is not necessary—lay the pieces flat if possible so they cook evenly. An 8-quart pot gives you more surface area, but any Instant Pot size will work for this method.

Add 1/2 cup of water or chicken broth for a 6-quart model, or 1 cup for an 8-quart model. The frozen chicken will release additional moisture as it cooks, but use the amount of liquid recommended for your pressure cooker if you prefer.

Season the chicken before pressure cooking if you like, or season afterwards when using it in another dish. Simple salt, pepper, and a pinch of garlic powder work well, but feel free to use your preferred spices or sauce.

How Long to Pressure Cook

Cooking time depends on the thickness of the breasts. Thin frozen breasts generally need 12 to 15 minutes under high pressure; thicker pieces require 15 to 20 minutes. Always allow a 10-minute natural pressure release, then quick-release any remaining pressure.

Shred with Mixer

Shredding cooked chicken is fast using a hand mixer right in the pot. This makes quick work of preparing shredded chicken for tacos, enchiladas, or casseroles. You can also slice or dice the breasts to use cold in chicken salad or pasta salad.

Cook with Sauce

You can cook frozen chicken directly in a sauce for added flavor. Barbecue, buffalo, salsa, or salsa verde are all excellent choices—just add enough liquid for the Instant Pot to reach pressure and cook as directed for plain chicken. The sauce will infuse the meat while it cooks.

How to Store

Store cooked chicken in a covered container in the refrigerator for 3 to 4 days. For longer storage, freeze the cooked meat in a freezer-safe container. For best quality, use frozen cooked chicken within four to six months.

Tips for Success

• Freeze chicken breasts flat in a single layer inside a freezer bag when possible. This makes it easier to lay them flat in the Instant Pot and promotes even cooking.
• Avoid cooking one large solid lump of frozen chicken. Pieces stuck together are okay if you can separate them a bit; large, dense lumps may not cook through evenly.
• Always check doneness with a meat thermometer. The internal temperature should reach at least 165°F (74°C).
• If the chicken has not reached 165°F after the initial cycle, cook for an additional 3–5 minutes under pressure and check again.
