How to Make Skinny Chicken Fajita Soup Step by Step
This soup comes together quickly and easily. Follow these steps for the best results.
Step 1: Prep Your Ingredients
Before cooking, take a few minutes to prepare everything.
- Slice the onions and bell peppers
- Mince the garlic
- Dice or shred the chicken
Prepping first makes cooking smooth and stress-free.
Step 2: Sauté the Vegetables
Heat the olive oil in a large pot over medium heat.
Add the sliced onions and bell peppers.
Cook for about 5 minutes, stirring occasionally, until they soften and release their natural sweetness.
Add the minced garlic and cook for 30 to 60 seconds until fragrant. Be careful not to burn it.
This step builds the flavor base of the soup.
Step 3: Add Chicken and Spices
Add the chicken directly to the pot with the vegetables.
Sprinkle in the chili powder, cumin, paprika, oregano, salt, and pepper.
Stir well so the chicken and vegetables are evenly coated with the spices. Cook for about 2 to 3 minutes to allow the seasonings to bloom.
Step 4: Add Broth and Tomatoes
Pour in the chicken broth and the can of diced tomatoes with their juices.
Stir everything together and bring the soup to a gentle boil. Once boiling, reduce the heat and let it simmer.
Step 5: Simmer Until Chicken Is Tender
Allow the soup to simmer uncovered for about 15 minutes, or until the chicken is fully cooked and tender.
If your chicken pieces are larger, you may need a few extra minutes.
The longer it simmers, the more developed the flavors become.
Step 6: Add Beans and Corn
Stir in the black beans and corn if using.
Simmer for another 3 to 5 minutes until everything is heated through.
These ingredients add extra protein, fiber, and texture to the soup.
Step 7: Finish with Lime Juice
Turn off the heat and stir in fresh lime juice.
Taste and adjust seasoning if needed. Add chopped cilantro if desired.
This final step brightens the soup and balances the spices perfectly.
