This recipe for Slow Cooker Refried Beans is one of the first recipes I learned how to make in my slow cooker. It is such a great side dish, and it makes a ton of beans.

How to make Slow Cooker Refried Beans

slow cooker with pinto beans, chicken bouillon, yellow onion, garlic and cayenne pepper.

You will need these ingredients:

Pinto beans
Sweet yellow onion
Chicken bouillon cubes
Garlic cloves
Cayenne pepper
Water
Salted butter

My method to add an amazing caramelized onion flavor to the beans is to brown thick sweet onions slices in a skillet.

My mom gave me a vintage Mexican cookbook and it used this method for their refried beans and it really does add so much flavor.

Should I soak my beans overnight?

You do not need to soak your beans overnight. If you cook the beans long enough, they cook up perfectly tender.

If you are adamant about soaking the beans you can, and use this same recipe, the cooking time is the same.

How long to cook:

Cover and cook the beans on the high setting for 5-6 hours or on the low setting for 10 hours.

Adding butter to make refried beans:

I add a stick of butter to my refried beans for flavor. Slow cooker refried beans don’t actually get refried in a pan rather they just get blended up. Adding the butter gives the flavor of the classic stove-top refried beans without the mess and work of frying.

How to make refried beans smooth:

For ultra-smooth beans, I recommend using an immersion blender. An immersion blender is a handheld blender that sticks down into the slow cooker and whizzes around pulverizing the beans. Note that I take out about half of the liquid from the pot before adding the butter and blending.

Don’t fret if you don’t have an immersion blender. The beans can be put into a regular blender and pulse until smooth or even easier use a potato masher and smash the beans right in the slow cooker.

How to thicken too runny refried beans:

Leave the lid off and let the moisture evaporate off.
OR Make a cornstarch slurry with a small amount of cold water and cornstarch. Stir into the beans.

Are your beans too thick?

Save the extra pinto bean broth from cooking, these juices are great for adding back into the beans and smoothing them out. If you did not save these, add a splash of water and stir.

If you happen to own two slow cookers, this recipe for Slow Cooker Refried Beans goes excellent with my Chicken Enchilada Casserole. If I am going all out, I will make this Spanish Rice Recipe from Lil Luna too.
