This soup transforms classic fajita ingredients into a warm, comforting bowl. It’s perfect for a quick weeknight dinner, using leftover cooked beef or chicken to speed things up.

You can adjust the broth thickness to your liking—from a hearty stew-like texture to a lighter soup. Serve it with all your favorite fajita toppings for a complete meal.

Method

Crush the garlic and let it sit while you prepare the other ingredients.
In a large pot, melt the fat over medium heat. Add the diced onion and cook until softened, about 3–4 minutes.
Add the sliced peppers and sauté for another 4–5 minutes, until they are slightly limp or browned. Stir in the garlic, salt, cumin, oregano, and taco seasoning, and cook for 1 minute until fragrant.
Add the cooked beef or chicken and stir for 1 minute to combine.
Pour in the diced tomatoes with their juice, the optional tomato paste or tomato sauce, the cooked brown rice, the sliced onion (the second onion), and the broth. Start with 4 cups of broth for a very thick soup, or use up to 8 cups for a thinner consistency.
Bring the soup to a boil, then remove from heat. It’s ready to serve.
Serve hot with your choice of toppings: sour cream, guacamole or avocado, chopped red onion, sliced sweet white onion, shredded cheese, jalapeños, tortilla chips, a squeeze of lime, and fresh cilantro.

💡 Tips

For a more intense fajita flavor, char the peppers and onions under the broiler or on a grill before adding them to the soup.
If you don't have taco seasoning, substitute with a mix of chili powder, cumin, paprika, garlic powder, and a pinch of cayenne.
Leftover soup thickens as it sits; thin with extra broth when reheating.
