Ingredients
- Olive Oil – Use oil of your choice
- Chicken Breasts – Cut into bite-size pieces. You can substitute with chicken thighs, rotisserie chicken or leftover chicken
Budget Tip: Boneless, skinless chicken thighs work great here and are usually cheaper per pound than chicken breast. Since they’re simmered in the broth, they stay juicy and shred easily. - Onion – Slice the onion evenly
- Bell Peppers, sliced – You can use any green peppers or red bell peppers
- Minced Cloves Garlic – Learn How to Mince Garlic Cloves
- Diced Tomatoes – A can of Rotel is a great substitute
- Chicken Broth – See Chicken broth substitutes
- Fajita Seasoning – Ingredient Note: Out of store-bought fajita seasoning or want to control the sodium? Use our Homemade Fajita Seasoning recipe instead — you likely already have the spices in your pantry.
- Ground Cumin – See Best Substitute for Cumin if you are out
- Chili Powder – See The Best Chili Powder Substitute
- Lime – Fresh lime juice is best
- Short on Time? Use Rotisserie Chicken: Skip searing raw chicken and stir in 3 cups of shredded rotisserie chicken after the vegetables have softened. Let the soup simmer for 10 minutes so the flavors blend, and you’ll shave about 10 minutes off the total time.
- For Serving – Tortilla strips, shredded cheese, hot sauce, sour cream, avocado, cilantro, or lime wedges, optional.

How to Make Chicken Fajita Soup
Step 1: In a large soup pot, heat olive oil over medium-high heat. Add the chicken and cook, stirring occasionally, until it’s no longer pink and reaches 165°F on an instant-read thermometer, about 5 minutes. Remove to a plate and set aside (it will finish cooking in the broth, so it’s okay if it’s not fully done yet).
Step 2 – In the same pot, add the onion and bell peppers. Cook for about 5 minutes, until softened. Add the garlic and cook for an additional 1 minute.
Step 3 – Return the chicken to the pot. Add the diced tomatoes, chicken broth, green chiles, fajita seasoning, cumin, chili powder, salt, and pepper. Bring to a boil, then reduce the heat and simmer for 15-20 minutes to let the flavors blend.
A Note on Spice Level: This soup has a warm, mild heat from the chili powder and fajita seasoning — not a spicy heat. If your family prefers things extra mild, start with half the chili powder and add more to taste at the end. If you love heat, stir in a diced jalapeño with the onions and peppers.
Step 4 – Pour in the lime juice just before serving for a fresh, tangy kick. Ladle the soup into bowls and top with tortilla strips, cheese, sour cream, avocado, cilantro, or lime wedges, as desired. Enjoy!
Recipe Tips
- Cut Veggies Evenly – Slice peppers and onions into uniform strips so they cook evenly and keep that fajita-style look.
- Don’t Skip the Lime – A squeeze of fresh lime juice at the end brightens up all the smoky, savory flavors.
- Meal Prep Friendly: Portion the finished soup into individual containers once it’s cooled, leaving the toppings out. It keeps well in the fridge for lunches all week — just add fresh toppings right before eating so the tortilla strips and cheese stay crisp.
- Leftover Makeover: Turn leftover soup into fajita rice bowls — spoon the soup over cooked rice and let it soak in slightly instead of serving it brothy. Or drain most of the liquid with a slotted spoon and pile the chicken and veggies into warm tortillas for quick fajita tacos.
Can I Make This in the Slow Cooker?
Yes! Add the raw chicken, onion, peppers, garlic, tomatoes, broth, green chiles, and seasonings to the slow cooker and cook on low for 6-7 hours or high for 3-4 hours. Shred the chicken right in the pot, then stir in the lime juice before serving. For exact measurements and step-by-step slow cooker directions, see our Crock Pot Chicken Fajita Soup recipe.
Variations Ideas
- Creamy Texture – Stir in ½ cup heavy cream or a block of cream cheese for a richer, creamy twist.
- Spicy РAdd jalape̱os, chipotle peppers in adobo, or cayenne pepper for more heat.
- Vegetarian Fajita Soup – Replace chicken with black beans or roasted vegetables like mushrooms, zucchini, corn, and sweet potatoes.
- Picky Eater Friendly: If your kids are hesitant about visible peppers and onions, dice them extra small so they blend into the broth instead of standing out, or blend a cup of the finished soup with an immersion blender before serving to thicken it and hide the veggies completely.
Homemade vs. Takeout: The Real Savings
A single order of chicken fajitas at a sit-down Mexican restaurant typically runs around $20 per person once you add a drink and tip. This entire pot of soup costs about $23 total, or roughly $2.88 per serving — meaning you can feed a family of six for close to the price of one restaurant plate. Make a double batch on a Sunday and you’ve got budget-friendly lunches and dinners covered for most of the week.
