The Night We Turned Fajitas into Soup

Print

This recipe was born out of pure, unadulterated hunger and a little bit of kitchen chaos. Picture this: It’s a chilly Friday night, and my family has a serious case of the “fajita fix.” I’ve got all the ingredients, the music is on, and I’m ready to sizzle. But as fate would have it, my trusty cast iron skillet decides it’s the perfect moment to launch a piece of bell pepper directly onto the floor, our cat is weaving figure-eights around my ankles hoping for a dropped treasure, and I realize we’re down to, like, two tortillas.

In a moment of “aha!” inspiration (or maybe just desperation), I looked at the beautifully seasoned chicken and peppers in the pan and thought, “What if I just… add broth?” I poured in some chicken stock, tossed in a can of tomatoes, and in less than 20 minutes, we were diving into the most incredible, soup-ified version of our favorite meal. It was a happy accident that’s now a forever staple. It proves that sometimes, the best recipes come from embracing the beautiful mess of real-life cooking.

Gather Your Ingredients

Here’s your shopping list for flavor town! The beauty of this soup is its flexibility, so I’ve included my favorite tips and swaps for you.

• 1 tablespoon olive oil – This is our cooking base. Avocado oil works beautifully here, too!
• 1 pound boneless, skinless chicken breasts or thighs – Chef’s Insight: I’m Team Thigh all the way for soup! They stay incredibly juicy and tender, even if you simmer a little longer. But breasts work perfectly if that’s what you have on hand.
• 1 onion, diced – A yellow or white onion brings that classic, sweet-savory foundation.
• 1 red bell pepper, sliced & 1 green bell pepper, sliced – Chef’s Insight: Don’t stop here! Throw in an orange or yellow pepper for a rainbow of color and sweetness. Using a mix makes the soup look so vibrant and happy.
• 3 cloves garlic, minced – Because, well, garlic is life. Fresh is best for that pungent, aromatic kick.
• 1 teaspoon chili powder, 1 teaspoon cumin, 1 teaspoon smoked paprika – This is the holy trinity of fajita flavor! The smoked paprika is the secret star—it gives that “grilled” taste without ever lighting a fire. If you only have sweet paprika, it’ll still be great, but smoked is a game-changer.
• ½ teaspoon oregano – A little earthy, herbal note to round everything out.
• 1 (14.5 oz) can diced tomatoes – They add body and a touch of bright acidity to the broth. Fire-roasted diced tomatoes are my go-to for an extra layer of smoky flavor.
• 4 cups chicken broth – Use a good-quality broth, as it forms the base of our soup. Low-sodium is best so you can control the salt level.
• 1 cup corn & 1 cup black beans – Substitution Tip: Frozen, canned, or even fresh off the cob! Just be sure to rinse and drain the black beans well. You can swap in pinto beans or kidney beans if you prefer.
• Salt and pepper, to taste – We’ll season at the beginning and then do a big taste-test at the end.
• Optional toppings: The Fun Part! Shredded cheese, sour cream (or Greek yogurt), creamy avocado, crunchy tortilla strips, and a big squeeze of fresh lime juice. Don’t you dare skip the toppings!

Let’s Make Some Magic: Step-by-Step

Ready to see how quickly this all comes together? Follow these steps, and you’ll be a fajita soup pro in no time.

1. Brown that Chicken: Heat your olive oil in a large Dutch oven or heavy-bottomed pot over medium heat. Add your diced chicken, season it generously with a good pinch of salt and pepper, and cook until it’s lightly browned on the outside. It doesn’t need to be cooked all the way through just yet! Chef’s Hack: Getting a nice sear on the chicken here builds a TON of flavor in the bottom of the pot (that’s called fond, and it’s liquid gold!). Remove the chicken to a plate and set it aside.
2. Sauté the Veggies: In that same beautiful, flavorful pot, add your diced onion and sliced bell peppers. Sauté them for 5-6 minutes, until they’ve started to soften and get a little sweet. You’ll hear a gentle sizzle—that’s the sound of flavor developing! Now, add the minced garlic and cook for just 30 seconds more until it’s incredibly fragrant. Chef’s Tip: Don’t let the garlic burn! Burnt garlic turns bitter, so we’re just taking the raw edge off.
3. Toast Those Spices: This is my favorite step! Sprinkle the chili powder, cumin, smoked paprika, and oregano right over the veggies. Stir constantly for about 1 minute. You’ll smell the spices blooming and becoming incredibly aromatic. Toasting them wakes them up and makes their flavor so much deeper and more complex.
4. Bring it All Together: Now, pour in the diced tomatoes (with their juices), the chicken broth, the corn, and the rinsed black beans. Scrape any of those delicious browned bits from the bottom of the pot—that’s where the magic is! Return the browned chicken (and any accumulated juices) to the pot. Give everything a big, happy stir.
5. Simmer to Perfection: Bring your soup up to a lively boil, then immediately reduce the heat to low and let it simmer gently, uncovered, for 15-20 minutes. This isn’t a hard, rolling boil, but a few lazy bubbles breaking the surface. This time allows the flavors to get to know each other, mingle, and create one harmonious, delicious broth. The chicken will finish cooking and become perfectly tender.
6. The Final Touch – Taste! Before you serve, do the most important thing: taste it! Does it need another pinch of salt? A crack of black pepper? Maybe another dash of cumin? This is your soup—make it sing to your taste buds!

How to Serve Your Masterpiece

Ladle this beautiful, steaming soup into big, cozy bowls. Now, for the grand finale: the topping bar! I like to set out little bowls of shredded Monterey Jack or cheddar cheese, a big dollop of cool sour cream, chunks of creamy avocado, a handful of crunchy tortilla strips for texture, and, most importantly, a wedge of fresh lime. Squeezing that lime juice over the top right before you eat is non-negotiable—it brightens up the entire bowl and makes all the flavors pop!

Make It Your Own: Delicious Variations

This soup is a fantastic canvas for your creativity! Here are a few of my favorite twists:

• Creamy Dreamy Version: Stir in ½ cup of heavy cream or full-fat coconut milk during the last 5 minutes of simmering for a rich, velvety broth.
• Spice It Up: Add a diced jalapeño (seeds and all for more heat!) with the bell peppers, or stir in a tablespoon of chopped chipotles in adobo for a smoky kick.
• Make it Zesty Lime-Cilantro: Stir in the juice of one whole lime and ¼ cup of chopped fresh cilantro right before serving.
• Instant Pot/Pressure Cooker Friendly: Use the sauté function for steps 1-3. Add all remaining ingredients (except toppings), seal, and cook on high pressure for 8 minutes. Quick release, and it’s done!
• Vegetarian/Vegan Swap: Skip the chicken, use vegetable broth, and add an extra can of beans or a cup of quartered mushrooms for heartiness.

Anna’s Chef Notes & Kitchen Stories

This recipe has evolved so much since that first chaotic kitchen night! I’ve learned that a splash of fresh lime juice at the end is the ultimate flavor brightener, and that letting the soup sit for 10-15 minutes off the heat before serving somehow makes it even better—the flavors have a chance to settle and deepen.

One time, I was filming a quick video of me making this and was talking so animatedly that I accidentally used a tablespoon of cumin instead of a teaspoon. Let me tell you, it was… intensely earthy. My husband, bless him, ate two bowls with a brave smile. We now call that version “Cumin Catastrophe Soup” and laugh about it every time. The moral of the story? Mistakes happen, and sometimes they’re delicious (and sometimes they’re just a good story!). Cooking is an adventure, not a test.

Your Questions, Answered!

I’ve gotten so many wonderful questions about this soup over the years. Here are the most common ones to help you out!

• Can I make this in a slow cooker? Absolutely! Sauté the chicken and veggies in a skillet first (don’t skip this for flavor!), then transfer everything to your slow cooker. Cook on LOW for 6-7 hours or HIGH for 3-4 hours.
• My soup is a little bland. How can I fix it? No worries, this is an easy fix! The most common culprit is under-salting. Add salt in small increments, tasting as you go. Also, try adding an extra ½ teaspoon of each spice (chili powder, cumin, paprika) and a big squeeze of fresh lime juice. Acid and salt are fantastic at waking up flavors.
• How long does leftover soup last? Stored in an airtight container in the fridge, it will be perfect for 3-4 days. The flavors get even better the next day! You can also freeze it for up to 3 months. Thaw overnight in the fridge and reheat gently on the stove.
• The chicken turned out a bit tough. What happened? This usually means it was slightly overcooked. If you’re using chicken breasts, they cook quickly. Try dicing them a bit larger, or for foolproof tenderness, use chicken thighs next time—they are much more forgiving!
