Chicken Fajita Burritos with Peppers & Onions

I used to think burritos were just a vehicle for leftover scraps. Then I perfected this recipe. Most people are overcomplicating their weeknight dinners with a dozen pans and zero flavor.

This isn’t just another wrap; it’s a flavor bomb wrapped in a tortilla. My Chicken Fajita Burritos with Peppers & Onions are the hero your boring meal prep needs. They are juicy, packed with flavor, and stupidly easy to make.

Forget takeout. This is your new secret weapon.

It’s all about the sizzle, right? That iconic sound you get at a restaurant is actually achievable at home.

The magic happens when the seasoned chicken and colorful bell peppers hit a screaming hot skillet. The caramelization on those peppers and onions adds a sweetness that balances the savory spices perfectly. It’s a textural dream: tender chicken, soft peppers, and a warm, fluffy tortilla.

Why pay for delivery when you can create something better in your own kitchen?

Ingredients

Gathering your mise en place makes this process fly by. The ingredient list is simple, but a couple of items are non-negotiable for maximum flavor. Don’t you dare skip toasting those tortillas!

  • 1.5 lbs boneless, skinless chicken breasts, sliced into thin strips
  • 3 bell peppers (I use a mix of red, yellow, and green), thinly sliced
  • 1 large yellow onion, thinly sliced
  • 2 tbsp olive oil, divided
  • 1 packet fajita seasoning (or 2 tbsp of your favorite blend)
  • 4 large flour tortillas (burrito-size)
  • 1 cup shredded Monterey Jack or cheddar cheese
  • 1/2 cup sour cream or Greek yogurt
  • Optional: fresh cilantro, lime wedges, hot sauce

Step-by-Step Instructions

  1. Season the chicken. Toss your chicken strips with the fajita seasoning and 1 tbsp of olive oil.

    Let it hang out for 5 minutes while your skillet heats up. This little rest allows the flavors to really cling to the meat.

  2. Cook the chicken. Heat a large skillet over medium-high heat. Add the chicken in a single layer and cook for 5-7 minutes, until cooked through and nicely browned.

    Remove the chicken and set it aside on a clean plate.

  3. Sauté the veggies. In the same skillet, add the remaining 1 tbsp of oil. Throw in your sliced peppers and onions. Cook for 6-8 minutes, stirring occasionally, until they are softened and have those beautiful charred edges.
  4. Combine everything. Add the cooked chicken back into the skillet with the peppers and onions.

    Give everything a good stir to combine and heat through for another minute. Squeeze a little fresh lime juice over the top for a bright kick.

  5. Warm the tortillas. This is the secret step! Briefly heat each tortilla over a gas flame or in a dry skillet for about 15 seconds per side.

    This makes them pliable and prevents tearing when you roll your burrito.

  6. Assemble the burritos. Lay a warm tortilla flat. Down the center, add a generous portion of the chicken fajita mixture. Top with cheese, a dollop of sour cream, and any other extras you love.
  7. Roll it up. Fold in the sides of the tortilla, then roll it up tightly from the bottom, tucking the filling in as you go.

    Place it seam-side down to seal the deal. Repeat with the remaining tortillas and filling.

Storage Instructions

These are the ultimate make-ahead meal. Let the filling cool completely before you assemble to avoid a soggy tortilla situation.

For the fridge, wrap each burrito tightly in parchment paper and then foil. They will stay fresh for up to 3 days. For the freezer, use the same wrapping method and store them in a freezer bag for up to 3 months.

Reheat from frozen in the oven at 375°F for 25-30 minutes, or until hot all the way through.

  • Incredibly Versatile: The base recipe is a blank canvas.

    You can easily adjust the spice level, swap proteins, or load up on extra veggies to suit your taste.

Common Mistakes to Avoid

  • Overstuffing the tortilla. You’re ambitious, I get it. But too much filling guarantees a blowout. Show some restraint.
  • Using cold tortillas straight from the package. This is the number one reason burritos tear.

    Heating them is non-negotiable for a pliable, sturdy wrap.

  • Not letting the filling cool. Assembling with piping hot filling steams the tortilla from the inside out, leading to a sad, soggy mess. Patience is a virtue.

Alternatives and Variations

This recipe is wonderfully adaptable. For a low-carb or keto version, serve the filling in a bowl over cauliflower rice or use large lettuce leaves as wraps.

To make it gluten-free, simply use your favorite GF tortillas. For a vegetarian or vegan twist, swap the chicken for seasoned black beans, lentils, or tofu and use vegan cheese and sour cream. You can also try using steak or shrimp instead of chicken for a different protein option.

FAQs
