Expert Tips
- Avoid Overcooking The Chicken: Check the texture and taste as you go. No one likes overly cooked, dried out chicken! And be sure there’s enough liquid in your slow cooker – this will come from the canned tomatoes and the chicken will release juices naturally as it cooks. This will keep it moist and tender. If needed, add a splash of water or broth.
- Shred the Chicken in Slow Cooker: Shed it with two forks directly in the base of your crockpot for easy cleanup.
- Go Low-Sodium: Use the low-sodium canned beans and salsa to control how salty this dish is. You can always add in more on your own.
- Add a Squeeze of Lime: At the end, right before serving, for brightness.
- Adjust Spice Level: If you like it spicy, use hot salsa. Or add a mild variety for less heat. Experiment with your favorite types.
- Freezer-Friendly Meal Prep Recipe: This is a great freezer-friendly recipe to help with meal prep. Cook, then cool, and portion into freezer safe zip top bags or airtight containers for an easy meal whenever you need it. Simply grab what you need, thaw in the fridge, and you’ve got lunch or dinner at the ready.
Substitutions and Variations
- Use Chicken Thighs: Breasts are great, but try chicken thighs for extra juiciness. You could even use a combination of both.
- Add Veggies: Add in diced bell peppers or onions for even more flavor and color.
- Make It Spicy: Add jalapeños or a chopped chipotle chili for some heat.
- Make It Low-Carb: Serve this over cauliflower rice for a filling and delicious low-carb meal.

What To Serve with Fiesta Chicken
I like to set up a taco bar or burrito bowl bar for my family when we have this chicken recipe. That way everyone can make their own meal to their liking and everyone’s plate is clean by the end of dinner!
- Rice or Cilantro Lime Rice
- Tortillas or Taco Shells
- Salad Greens: As the base for a taco bowl, or to top with.
- Toppings: Avocado, Greek yogurt, or Sour cream
- Tortilla chips: For scooping.
Storage
This is a great meal for leftovers. They can be repurposed into a completely different dish the next day! Store leftovers in an airtight container in the fridge for up to 4 days, then reheat over medium heat on the stove or in the microwave until warm. Add a splash of water or broth to refresh, if needed.
You can freeze leftovers in an airtight container in the freezer for up to 3 months, or you can even prep this whole recipe in advance and store in the freezer as a make-ahead meal. When you’re ready to enjoy, thaw in the fridge overnight, then reheat on the stove over medium heat, covered, with a splash of broth if needed.
Perfect Presentation Platters
Crockpot: I used my favorite 8-quart crockpot from Walmart, which is at a great price!
Chopping Boards: I use boards all the time, both for prep and serving. I especially love a marble and wood combo, like this option from World Market. Some of my other favorites are this white striped wooden board from Kirklands, this mango wood board from Target, and this marble and wood rectangular tray from JC Penney. I also used my go-to MacKenzie Childs checkered chopping board!
Serving Bowls: I used these MacKenzie-Childs serving bowls for this recipe. There is something for everyone, no matter your personal style! I love this black-and-white coordinating set or this colorful terracotta Spanish style. Walmart has these dreamy gray stoneware bowls with silver rims for a great price, or Target has these fun red-and-white striped bowls.

FAQs
Yes! It’s full of lean protein from the chicken, healthy ingredients like tomatoes and hearty beans, and can be served as a topping for salads, over rice or brown rice, or in fresh tortillas as tacos. It’s a filling and nutritious meal for anyone.
You can, but for food safety reasons, we recommend fully thawing the chicken the night before in the fridge, then adding to the slow cooker.
If you’d like it to be! You can control the type of salsa, ingredients, and spices used. If you use a spicy salsa, this dish will have more heat than if you use a mild salsa. If you add jalapeños or chipotles in adobo, you’ll definitely have a kicked up recipe. And if you add cayenne or extra chili powder, you’ll have an extra spiced fiesta chicken. It’s a personal preference.
Absolutely. This is the perfect meal prep recipe. Make it ahead of time, cool, then store in the fridge or freezer (depending on when you’re ready to eat it) in an airtight container until it’s time to serve. It’s a huge time saver!
