Cooking frozen chicken breasts in a slow cooker, also known as a Crockpot, is one of the easiest ways to prepare moist, flavorful chicken for meals or recipes. With just a few minutes of prep time, you can pop a pack of frozen chicken breasts into the slow cooker and walk away, letting the appliance do the work of gently cooking the chicken to perfection.
But exactly how long does it take to cook frozen chicken breasts in a slow cooker? Here is a complete guide to timing, tips and tricks for ensuring your frozen chicken comes out tender and delicious every time you use this handy kitchen shortcut.
Why Use a Slow Cooker for Frozen Chicken?
Cooking frozen chicken in the slow cooker offers several advantages
-
Hands-off cooking Once you add the chicken to the slow cooker no further cooking or attention is required. The appliance cooks the food unattended for as long as needed.
-
Tender, juicy chicken: The low, moist heat of the slow cooker gently cooks the chicken, keeping it incredibly moist and tender.
-
Adds flavor: Spices, herbs and other flavorings have time to permeate the chicken over several hours of cooking.
-
Safety: The prolonged cooking time ensures the chicken is cooked through to a safe internal temperature.
-
Flexibility: Use the cooked chicken in a variety of recipes, from casseroles to sandwiches, salads, wraps and more. Shredded slow cooker chicken also freezes beautifully.
How Long to Cook Frozen Chicken Breasts in a Slow Cooker
Cooking time can vary based on the size and number of chicken breasts, how frozen they are and your slow cooker model. Here are general guidelines:
-
2-3 hours on HIGH: 1-2 lightly frozen boneless, skinless chicken breasts.
-
3-4 hours on HIGH: 3-4 chicken breasts or a pack of frozen chicken tenderloins.
-
6-8 hours on LOW: 4-6 frozen boneless, skinless chicken breasts.
-
8-10 hours on LOW: A family pack of 6-8 large frozen chicken breasts.
Checking the internal temperature and shredability of the chicken is the best way to tell when it’s finished cooking.
How to Know When Frozen Chicken is Done in the Slow Cooker
Relying on cooking time alone isn’t a foolproof way to know when chicken cooked from frozen in the slow cooker is fully cooked and ready to eat. Use these visual and temperature cues:
-
165°F internal temperature: Check the temp in the thickest part of the chicken using a food thermometer. 165°F indicates it’s safe to eat.
-
Shredding: The chicken should shred or pull apart easily with a fork. If it’s still stiff or firm, cook longer.
-
Clear juices: Prick the chicken with a fork; the juices should run clear rather than pink or red.
-
Visual color: The chicken should be white and opaque throughout when sliced or shredded, with no pink spots.
Always double check the temp even if the chicken looks done. Frozen chicken takes longer than fresh to reach a safe internal temperature.
Tips for Cooking Frozen Chicken Breasts in the Slow Cooker
Follow these simple tips for foolproof frozen chicken cooked to juicy perfection in your Crockpot:
-
Partially thaw: Chicken thawed to refrigerator temperature may cut cooking time slightly. But you can absolutely cook fully frozen chicken in the slow cooker.
-
Add flavor: Season chicken with spices, chopped onions, garlic, lemon, lime or fresh herbs. A small amount of olive oil or cooking oil and salt enhances flavor.
-
Lift and separate: Arrange chicken so pieces aren’t stacked. Lifting and shuffling periodically allows heat to circulate.
-
Don’t peek! Resist lifting the lid to peek or stir, which increases cooking time.
-
Shred: Use two forks to shred or pull cooked chicken into bite size pieces for tacos, casseroles, sandwiches and more.
-
Make it a meal: Cook chicken in broth along with potatoes, carrots and celery for an easy homemade soup.
How to Freeze and Store Slow Cooker Chicken
Leftover cooked chicken from the slow cooker freezes beautifully up to 3 months. Here’s how:
-
Let chicken cool completely, then package in freezer bags, wrap tightly in foil or place in airtight containers.
-
Exclude any cooking liquids, as they can cause freezer burn.
-
Flatten packages to freeze flat for efficient storage and faster thawing.
-
Label bags with contents and date.
-
Thaw in refrigerator overnight before using.
-
Use within 3 months for best quality.
Freezer chicken is terrific to have on hand for quick weeknight meals.

FAQs About Cooking Frozen Chicken in the Slow Cooker
Here are answers to some frequently asked questions about using the slow cooker to cook frozen chicken breasts:

Can You Freeze Chicken After Making It in the Slow Cooker?
Not only can you freeze it, but I strongly suggest you do!

I love to buy chicken when it’s on sale and plan ahead for various future meals. Chicken is so versatile that it’s easy to think of ways to use it without feeling like it’s getting old. Even a basic chicken salad sandwich to bring to work will feel like a brand-new meal!
Can I Cook Frozen Chicken in a Crock Pot?
The USDA recommends thawing meat or poultry before putting it into a slow cooker.
They cite the fact that frozen pieces will take longer to reach safe internal temperatures, which is a known cause for foodborne illness. Additionally, frozen or partially frozen foods will also cool everything else in the slow cooker and contribute to a longer cooking time and a less safe cooking environment.
With all of this in mind, some meals are designed for use in the slow cooker that may be frozen. The manufacturer’s instructions will be your best bet for food safety and preparation.
The USDA has also addressed slow cooker food safety guidelines that will help users make the best choices and use the best practices when making meals with a crock pot. We strongly suggest reading these no matter what you plan to make!
When preparing chicken in the slow cooker, it is helpful to make the chicken by itself, without any other sides included. This prevents the cooling of other food items, and the transfer of temperatures between ingredients.
Cooking frozen chicken in the crock pot can make a great shredded or pulled chicken that can be used for multiple recipes.
