No, one minute of pressure cooking will not cook frozen chicken breasts through. Plan for 8 to 12 minutes at high pressure, plus time to pressurize and release. An Instant Pot is an electric pressure cooker that cooks food with trapped steam under pressure.
That added time matters for meal prep. The full frozen-breast cycle runs about 25 to 35 minutes. USDA's Food Safety and Inspection Service says cooking poultry directly from frozen is safe, but takes about 50 percent longer than thawed.

What Pressure Time Fits Your Breasts?
Use size to pick time. Home economist Getty Stewart recommends about 8 minutes at high pressure for small 5 to 6 ounce frozen breasts and about 10 minutes for large 7 to 9 ounce breasts, in her tested Instant Pot timing guide. Instant Brands directs cooks to place frozen breasts with liquid in the pot and Pressure Cook on High for 12 minutes with quick release, in the official Instant Brands chicken breast recipe.
Treat very thick pieces differently. Breasts over about 10 ounces, or breasts frozen stuck together, may stay underdone in the standard time. Separate them into one layer before cooking. Give the largest pieces 12 to 15 minutes at pressure.
Why Is Total Time Longer Than 1 Minute?
Frozen meat extends every stage. The pot typically needs 10 to 15 extra minutes to come to pressure, plus 5 to 10 minutes of release. That makes a frozen-breast cycle about 25 to 35 minutes total.
The longer pressure time also follows food-safety guidance. USDA's food-safety service says frozen meat needs about 50 percent more cook time than thawed meat. Frozen breasts also take longer than fresh breasts to pressurize.

How Do You Set Up the Pot?
Start with enough thin liquid. Instant Pot manuals state that a 6-quart pot needs at least about 1 cup of water or broth to build steam, while larger pots need about 1.5 to 2 cups, in the Instant Pot Pro Plus manual. Too little liquid can prevent pressurizing and trigger a Burn warning.
Arrange the meat for even cooking. Use separated breasts in a single layer. Avoid stacking frozen clumps.
- Add 1 cup broth or water for a 6-quart pot.
- Place separated frozen breasts in one layer.
- Lock lid, set valve to sealing, and cook on High Pressure for the size-based time.
- Let pressure release before opening and checking temperature.
How Do You Finish for Safety and Juiciness?
Release pressure before cutting. Tested frozen-breast methods use 5 to 10 minutes natural pressure release before venting. Natural release means leaving the sealed pot undisturbed so pressure drops slowly.
Check the thickest part with a food thermometer. FoodSafety.gov requires all poultry to reach 165 degrees F, measured with a thermometer, according to the FoodSafety.gov temperature chart. If the thickest part reads below 165 degrees F, reseal the pot and cook about 2 minutes more at pressure.
