Health notes

High protein: Shredded chicken keeps you full for hours.

Low carb vegetables: Bell peppers and onion add color and fiber with almost no net carbs.

Creamy but light: Cream cheese or Greek yogurt creates richness without excess carbs.

Bold spices: Chili powder, cumin, and paprika deliver classic fajita flavor cleanly.


Key element — bloom the spices

Toast the chili powder, cumin, and paprika in the pot for 30–60 seconds before adding liquid. This wakes up the oils in the spices and gives the soup authentic fajita depth instead of a flat, raw spice taste.

Instructions

1 — Cook the chicken

Season chicken with a pinch of salt and pepper. Heat olive oil in a large pot over medium-high heat. Add chicken and cook 5–6 minutes per side until cooked through. Remove, shred with two forks, and set aside.

2 — Sauté the vegetables

In the same pot, add onion and bell peppers. Cook 4–5 minutes until softened and lightly charred. Stir in garlic for 30 seconds.

3 — Bloom the spices

Add chili powder, cumin, smoked paprika, garlic powder, salt, pepper, and cayenne if using. Stir 30–60 seconds until fragrant.

4 — Simmer

Pour in chicken broth and diced tomatoes. Bring to a boil, then reduce heat and simmer 10 minutes. Stir in the shredded chicken and cream cheese until melted and smooth. Add shredded cheese if using.

5 — Finish and serve

Taste and adjust seasoning. Ladle into bowls. Top with a dollop of sour cream, cilantro, green onions, and any optional toppings. Serve hot.


Pro tips

Tip 1: Soften the cream cheese first so it melts smoothly without lumps.

Tip 2: Do not skip blooming the spices — it makes a big difference in flavor.

Tip 3: For extra creamy texture, blend a cup of the soup and stir it back in.

Tip 4: The soup thickens slightly as it cools; add a splash of broth when reheating if needed.

Tip 5: Rotisserie chicken cuts the active time significantly on busy nights.
