Ingredients
Method
- Sauté the aromatics: Warm 1–2 tablespoons of oil in a large pot over medium heat. Add diced onion, bell pepper, and a pinch of salt. Cook 4–5 minutes until softened. Stir in garlic and jalapeño; cook 30–60 seconds until fragrant.
- Build the base: Add 1–2 tablespoons of tomato paste. Cook, stirring, for 1 minute to caramelize. Sprinkle in cumin, chili powder, smoked paprika, oregano, and a few grinds of pepper. Toast the spices for another 30 seconds.
- Add liquids: Pour in the diced tomatoes and 6 cups of chicken broth. Stir to combine, scraping up any browned bits from the bottom of the pot.
- Simmer: Bring to a gentle boil, then reduce to a simmer for 10 minutes to let the flavors blend.
- Add the chicken: Stir in the shredded chicken. Simmer 5–10 minutes more, just until heated through and the soup tastes cohesive. If it seems too thick, add a splash of broth.
- Season and brighten: Add salt to taste (start with 1 teaspoon and adjust). Squeeze in the juice of half a lime, taste, and add more if needed. Stir in a handful of chopped cilantro.
- Serve with toppings: Ladle into bowls and top with shredded cheese, avocado slices, extra cilantro, a dollop of sour cream, and a squeeze of lime. For crunch, add a small handful of crushed pork rinds in place of tortilla strips.

How to Store
- Refrigerator: Store in an airtight container for 4–5 days.
Keep toppings separate for best texture.
- Freezer: Cool completely, then freeze in portions for up to 3 months. Thaw overnight in the fridge.
- Reheating: Warm gently on the stove over medium-low heat, or microwave in short bursts. Add broth if it thickens after chilling.
Why This is Good for You
- Keto-friendly macros: Low in net carbs, with protein from chicken and satisfying fats from avocado, cheese, and sour cream.
- Rich in micronutrients: Bell peppers, tomatoes, and cilantro add vitamin C, potassium, and antioxidants.
- Balanced and filling: The combo of protein and fat helps steady appetite and energy while keeping carbs in check.
- Anti-inflammatory spices: Cumin, chili powder, and paprika bring flavor along with potential antioxidant benefits.
Common Mistakes to Avoid
- Skipping the spice toasting: Not toasting the spices can make the soup taste flat.
A quick toast wakes them up.
- Overcooking the chicken: If your chicken is already cooked, add it near the end so it stays tender.
- Using sweetened tomatoes: Some canned tomatoes have added sugar. Choose no-sugar-added to keep carbs low.
- Overloading toppings: Cheese and sour cream are great, but too much can turn the soup heavy. Start modest and add as needed.
- Forgetting acidity: Lime juice makes the flavors pop.
Without it, the soup can taste dull.
Variations You Can Try
- Creamy version: Stir in a splash of heavy cream or a dollop of cream cheese at the end for extra richness.
- Green chili twist: Swap diced tomatoes for canned green chilies and tomatillo salsa (salsa verde). Add fresh spinach for color.
- Chipotle kick: Add 1–2 teaspoons of minced chipotle in adobo for smoky heat. Adjust to taste.
- Turkey or beef: Use leftover turkey or browned ground beef instead of chicken for a different protein profile.
- Veg-boost: Add zucchini or riced cauliflower in the last 5–7 minutes for more volume without many carbs.
- Slow cooker: Add all ingredients except toppings to the slow cooker and cook on low 4–6 hours.
Stir in lime and cilantro before serving.
FAQ
How many carbs are in this soup?
Carbs will vary by brand and toppings, but a typical serving without pork rinds or sour cream lands around 6–8 net carbs. Check your labels and portion sizes to be sure.
Can I make it dairy-free?
Yes. Skip the cheese and sour cream, and rely on avocado for creaminess.
The soup itself is naturally dairy-free unless you add cream or cheese.
What can I use instead of pork rinds for crunch?
You can top with toasted pumpkin seeds for a little crunch, though they do add some carbs. Another option is a sprinkle of shredded cheese baked into crisps.
Is this spicy?
It’s mildly spicy as written. If you’re sensitive to heat, skip the jalapeño and use mild chili powder.
If you love heat, add extra jalapeño or a pinch of cayenne.
Can I use raw chicken?
Yes. Simmer raw, cubed chicken in the broth for 12–15 minutes until cooked through, then shred or dice and continue with the recipe. Adjust cook time as needed.
How do I thicken the soup without flour or cornstarch?
Let it simmer uncovered to reduce slightly, or blend a small portion and stir it back in.
Adding a bit of cream cheese also creates a thicker, creamier texture.
What’s the best broth to use?
A good-quality, low-sodium chicken broth or bone broth works best. Bone broth adds body and extra protein without extra carbs.
