Ingredients:
- Chicken: 1.5 lbs boneless, skinless chicken thighs (or breasts, cubed)
- Olive Oil: 2 tablespoons
- Onion: 1 medium, chopped
- Bell Pepper: 1 medium (any color), chopped
- Garlic: 4 cloves, minced
- Jalapeño: 1, seeded and minced (optional, for heat)
- Chicken Broth: 8 cups (low sodium preferred)
- Diced Tomatoes: 1 (14.5 oz) can, undrained
- Tomato Paste: 2 tablespoons
- Chili Powder: 2 tablespoons
- Cumin: 1 tablespoon
- Smoked Paprika: 1 teaspoon
- Oregano: 1 teaspoon, dried
- Cayenne Pepper: 1/4 teaspoon (optional, for extra heat)
- Salt: To taste
- Black Pepper: To taste
- Lime Juice: 2 tablespoons, fresh
- Avocado: 1-2, diced, for topping
- Shredded Cheddar Cheese: For topping (optional)
- Sour Cream or Greek Yogurt: For topping (optional)
- Cilantro: Fresh, chopped, for topping
- Keto-Friendly Tortilla Chips or Crisps: For serving (optional)
Preparing the Chicken and Vegetables:
- First, let’s get our chicken ready. If you’re using chicken thighs, you can leave them whole or cube them into bite-sized pieces. If you’re using chicken breasts, I recommend cubing them for easier cooking and eating in the soup.
- Now, heat the olive oil in a large pot or Dutch oven over medium heat. Once the oil is shimmering, add the chicken. Cook the chicken until it’s browned on all sides and cooked through. This usually takes about 5-7 minutes, depending on the size of your chicken pieces. Make sure the internal temperature reaches 165°F (74°C).
- Remove the cooked chicken from the pot and set it aside. Don’t worry about cleaning the pot; we want to keep all those delicious browned bits for extra flavor!
- Add the chopped onion and bell pepper to the pot. Cook, stirring occasionally, until the vegetables are softened, about 5-7 minutes. You want them to be tender and slightly translucent.
- Add the minced garlic and jalapeño (if using) to the pot. Cook for another minute, stirring constantly, until fragrant. Be careful not to burn the garlic!
Building the Soup Base:
- Pour in the chicken broth, diced tomatoes (undrained), and tomato paste. Stir well to combine, scraping up any browned bits from the bottom of the pot. These browned bits are packed with flavor and will add depth to your soup.
- Add the chili powder, cumin, smoked paprika, oregano, and cayenne pepper (if using). Stir well to ensure all the spices are evenly distributed.
- Bring the soup to a simmer, then reduce the heat to low, cover, and let it simmer for at least 15 minutes. This allows the flavors to meld together and deepen. The longer it simmers, the better it will taste! You can even let it simmer for an hour or more for maximum flavor.
Finishing the Soup:
- Return the cooked chicken to the pot. Stir to combine and heat through.
- Season the soup with salt and black pepper to taste. Remember that chicken broth can sometimes be salty, so start with a small amount of salt and add more as needed.
- Stir in the fresh lime juice. This adds a bright, tangy flavor that really elevates the soup.
- If you want a thicker soup, you can use an immersion blender to partially blend the soup. Be careful not to over-blend it; you still want some texture. Alternatively, you can remove a cup or two of the soup and blend it in a regular blender, then return it to the pot.
Serving and Toppings:
- Ladle the soup into bowls.
- Top with your favorite toppings! I highly recommend diced avocado, shredded cheddar cheese, sour cream or Greek yogurt, and fresh cilantro.
- Serve with keto-friendly tortilla chips or crisps for dipping, if desired. These add a nice crunch and make the soup even more satisfying.
Tips and Variations:
- Spice Level: Adjust the amount of jalapeño and cayenne pepper to your liking. If you’re sensitive to heat, omit them altogether.
- Vegetables: Feel free to add other keto-friendly vegetables to the soup, such as zucchini, mushrooms, or spinach.
- Chicken: You can use shredded rotisserie chicken instead of cooking your own chicken. This is a great time-saver!
- Slow Cooker: This soup can easily be made in a slow cooker. Simply combine all the ingredients (except the toppings) in the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours. Shred the chicken before serving.
- Instant Pot: For a quick and easy version, you can make this soup in an Instant Pot. Sauté the vegetables in the Instant Pot, then add the remaining ingredients (except the toppings). Cook on high pressure for 10 minutes, followed by a natural pressure release for 10 minutes, then a quick release. Shred the chicken before serving.
- Thickening: If you prefer a thicker soup, you can add a small amount of xanthan gum. Start with 1/4 teaspoon and add more as needed, stirring constantly. Be careful not to add too much, as it can make the soup gummy.
- Dairy-Free: To make this soup dairy-free, omit the cheese and sour cream toppings. You can use a dairy-free sour cream alternative if desired.
- Storage: Leftover soup can be stored in the refrigerator for up to 3-4 days. It can also be frozen for up to 2-3 months.

And don’t be afraid to experiment with different toppings! A dollop of sour cream or Greek yogurt adds a creamy tang, while a sprinkle of shredded cheddar cheese provides a cheesy indulgence. For a bit of crunch, consider adding some crushed pork rinds – they’re a fantastic keto-friendly alternative to tortilla chips! You could even add some diced avocado for extra healthy fats and a creamy texture. I sometimes like to add a squeeze of lime juice right before serving to brighten up the flavors even more.
Serving suggestions are endless! This soup is delicious on its own, but it also pairs perfectly with a side salad or some keto-friendly bread. You can even serve it as an appetizer in small bowls at your next gathering. And if you have any leftovers (which is rare in my house!), they reheat beautifully, making it a great meal prep option for busy weeknights. I often double the batch so I can enjoy it for lunch throughout the week.
