Seriously, when you’re juggling after-school activities, work, and dinner, this recipe is a lifesaver for those busy weeknight dinners!
Ingredients Breakdown
Chicken Breasts
You’ll need 2 boneless, skinless chicken breasts, cut into 1-2 inch cubes. Chicken is the perfect base here, adding a lovely texture and protein-packed goodness. I prefer using fresh chicken, but you can also go for frozen, just make sure to adjust the cooking time. Just toss it in and let that slow cooker work its magic!
Onion
Using 1/2 cup diced onion gives your soup a solid flavor base. Onions are like the team captains of flavor in cooking! I usually prefer yellow onions for their sweetness, but white or red will work too. If you’re in a pinch, you can throw in some onion powder.
Garlic
Can’t forget 1 clove minced garlic! Garlic is basically the superstar of every kitchen, right? It adds that incredible aromatic quality. I highly recommend fresh garlic for this, but if you’re out, a teaspoon of garlic powder can step in just fine!
Black Beans
We’ll add in 15 ounces canned black beans, rinsed and drained. They not only make your soup hearty but also add fiber and protein! You can swap these for pinto beans or even chickpeas if that’s what you have laying around.
Kidney Beans
Next up, toss in 15 ounces canned kidney beans, rinsed and drained as well. Their slightly sweet flavor perfectly balances with the spices. You can easily switch these out for more black beans or any beans you have on hand.
Diced Green Chili Peppers
We want 4 1/2 ounces canned diced green chili peppers for that zing! The slight heat really amps up the flavor profile. If you like it spicier, diced jalapeños would be a fantastic substitute!
Diced Tomatoes
Add 14 1/2 ounces canned diced tomatoes (juice included) for that juicy tomato goodness. They keep the soup nice and saucy. If you want to switch it up, a can of fire-roasted tomatoes or even homemade tomato sauce could work wonderfully.
Chicken Broth
You’ll also need 2 1/2 cups low-sodium chicken broth to bring everything together. It’s the comforting liquid that rounds out the flavors. Feel free to switch it out for vegetable broth or homemade stock for a vegetarian version!
Corn
For a sweet pop, toss in 1 cup frozen or fresh corn. I prefer frozen corn for this recipe, it’s super easy to throw in! Seriously, just grab a handful and toss it in there.
Spices
Now, let’s spice things up! You’ll need the following:
- 1 tablespoon chili powder for that signature fiesta flavor.
- 1 teaspoon cumin for a warm, earthy undertone.
- 1/2 teaspoon cayenne pepper adjust to taste, my friend! I like it spicy, but you do you.
- 1/2 teaspoon black pepper and salt to taste. I usually finish with a couple of pinches and adjust as needed.
Lime Juice
Lastly, don’t skip on the juice of 1 lime! It brightens everything and brings those flavors to life. Fresh lime is best, but bottled lime juice will work in a pinch.
Fresh Cilantro
For finishing touches, I love using 1/2 cup freshly chopped cilantro. It adds a fresh flavor that’s just amazing. If you’re not a cilantro fan (I get it, not everyone is), parsley or even green onions could give a beautiful finish too!

How to Make Quick and Easy Slow Cooker Fiesta Chicken Soup
Combine All Ingredients: Toss all the ingredients into your slow cooker. No need to sauté anything here, just stir to mix! If you’re cooking on high, you can adjust the seasonings and taste at the end.
Set & Forget: Cover and set it to low. Now, that’s the beauty of slow cooking it’ll sweat and merge those flavors beautifully for 6-8 hours. During this time, your house is going to smell like heaven!
Shred the Chicken: About 30 minutes before serving, if you want shredded chicken (which I totally recommend), just shred the chicken in the slow cooker with two forks. Give it a good stir, then squeeze in that lime juice. Oh man, the flavors really pop then!
Serve & Garnish: When ready, scoop into bowls and top with freshly chopped cilantro. You could even add some avocado, cheese, or crunchy tortilla strips if you’re feeling fancy!
