From the archive: some recipes earn a permanent spot in the weeknight rotation, and this one did exactly that. The original post promised that even the pickiest eater at the table went back for seconds — which, in any busy household, is about as close to a five-star review as dinner gets.

These homemade chicken fajitas were written as the companion recipe to a DIY fajita seasoning, and the whole point of the dish is how unfussy it is. Ten minutes of prep, two skillets, and a seasoning mix you already have in the pantry. No packets with mystery sodium levels, no marinade you have to remember the night before. Just chicken strips, sweet peppers, and onions, cooked hot and fast, then simmered together until everything is coated in that smoky, warm spice.

What made the original post stick with readers, though, was not just the flavor — it was the freezer trick. The cooked chicken-and-pepper mixture freezes beautifully, which means one evening of cooking can quietly cover two or three future dinners. On the nights when everyone gets home late and nobody wants to think, a bag of this pulled from the freezer in the morning is the difference between a real meal and takeout.

The recipe

Serve the fajita mixture however your table likes it — tucked into warm tortillas with all the toppings, or spooned over a bed of shredded lettuce and spinach for a lighter, lower-carb plate. The original post leaned toward the salad version, topped with salsa, guacamole, and a little shredded cheese, and it remains a genuinely satisfying way to eat these.

Ingredients

  • 4 boneless, skinless chicken breasts, cut into thin strips
  • 4 tablespoons olive oil, divided
  • 3 tablespoons homemade fajita seasoning (chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and a pinch of cayenne)
  • 1 green bell pepper, seeded and cut into strips
  • 1 red bell pepper, seeded and cut into strips
  • 1 medium sweet onion, cut into strips
  • 1/2 cup water
  • Tortillas of your choice, or shredded lettuce and spinach for fajita salads
  • Toppings of your choice: salsa, shredded cheese, guacamole, sour cream, shredded lettuce

Instructions

  1. In a large skillet over medium heat, warm 2 tablespoons of the olive oil until hot.
  2. Add the chicken strips and cook until cooked through, 8 to 10 minutes. Transfer to a plate.
  3. In a second large skillet over medium heat, warm the remaining 2 tablespoons of olive oil. Add the peppers and onion and cook until lightly browned and tender, about 7 to 8 minutes.
  4. Combine the chicken with the peppers and onions in one pan.
  5. Add the fajita seasoning and water, stir well to coat everything, and simmer uncovered for about 15 to 20 minutes, until the sauce thickens and clings to the chicken.
  6. Serve warm in tortillas, or spoon about 1/2 cup of the mixture over a bed of lettuce and spinach and finish with salsa, guacamole, and a sprinkle of cheese.

How to freeze it

A reader asked in the original comments whether to freeze the mixture cooked or uncooked — a fair question, and the answer then still holds now. The cooked version freezes best. Let the finished chicken-and-pepper mixture cool completely, then pack it into freezer bags or containers in single-meal portions, pressing out as much air as you can. It keeps well for about three months. Thaw overnight in the fridge and reheat gently in a skillet with a splash of water to loosen the sauce.

If you prefer a freezer-to-skillet shortcut, you can also freeze the raw chicken strips tossed with the seasoning and sliced vegetables together in one bag. It will need a few extra minutes in the pan since the vegetables release more liquid from frozen, but it works — just cook until the chicken reaches a safe internal temperature of 165°F (74°C).

A few notes from the archives

The seasoning matters more than anything else here. A homemade blend lets you control the salt, which is the main complaint about store-bought packets, and it takes all of five minutes to mix a jar that will carry you through months of fajita nights. If you enjoy set-it-and-forget-it cooking, the mixture also adapts well to a slow cooker — add everything raw, cook on low for about four hours, and shred the chicken before serving.

However you serve them, this is the kind of recipe that quietly does its job: fast, flexible, freezer-friendly, and — most importantly — the sort of dinner that gets eaten without negotiation. That alone makes it worth a spot in the plan for the week.
