What’s to love about this recipe?

  • It’s filling! Although there are only three chicken breasts, this dish can easily serve up to six people when served with a side (or two). The large serving of protein along with the fajita veggies and cheese sauce is quaranteed to fill you up.
  • It’s so flavorful! From the fajita spice blend the chicken is marinated in to the slighty carmalized veggies and the rich and creamy cheese sauce this dish is popping with flavor.
  • It’s low carb and gluten-free! Aside from the white American cheese, this dish is clean and unprocessed. Additionally, it contains no gluten or carbs, making it a great choice to serve to guests or family that restrict one or both of these from their diets.

Ingredients + notes & substitutions

Ingredients for fajita stuffed chicken breasts with cheese sauce (see recipe card).
  • Chicken breasts: You will need three decent sized skinless chicken breasts or four smaller sized ones for this recipe.
  • Olive oil
  • Chili powder: Chili poweder is actually a mixture of several spices as well as ground chiles. It’s typically not very spicy so if you wanna take this dish up a notch heatwise, I would advise adding a teaspoon of cayenne as well.
  • Cumin: This warm and earthy spice is a great addition to almost any Mexican (inspired) dish including this one.
  • Garlic powder
  • Kosher salt
  • Oregano: If you have Mexican oregano, use that!
  • Onion powder
  • Black pepper
  • Paprika: Although the chili powder contains paprika, I like to add a little more.
  • Bell peppers: You will need two small to medium sized bell peppers of any color.
  • White onion: White onion is the traditional choice for fajitas, however, red is a perfectly suitable alternative.
  • White American cheese: Many Mexican resturants these days serve white cheese dip that is prepared with this type of cheese. Although, I typically shy away from “cheese products” white American cheese works wonderfully for cheese sauce because it melts so nicely. You will likely need to purchase it from the deli section at your local grocery store because it’s not typically available presliced and packaged.
  • Milk: For the cheese sauce.
  • Lime: Fresh squeeze lime juice is the perfect finishing touch for the chicken.
  • Cilantro: Garnishing the finished product with some cilantro adds some freshness. If you’re cilantro averse, skip it!

How do you make fajita stuffed chicken with cheese sauce? (+ tips)

  1. Slice each chicken breast lengthwise 3/4 of the way through. This is called butterflying (see photo below). Rub the outside of each breast with one teaspoon of olive oil then set aside.

3. Preheat your oven to 425 degrees.

4. Meanwhile, heat 1 tablespoon of olive oil in a medium skillet over medium-high heat. Once shimmering, add the sliced bell pepper and onion, sprinkle with 1/2 teaspoon salt, and cook, stirring occasionally, for five to seven minutes until slightly charred and softened. Remove from heat and set aside.

5. Heat two tablespoons of olive oil in a large oven-safe skillet, preferably cast-iron, over medium-high heat.

6. Place the chicken breasts in the hot skillet and cook for five minutes until you have a nice sear then flip and cook another five minutes. Fill the chicken breasts with the sautéed veggies and use toothpicks to secure them shut. ***Don’t worry if you are unable to fit all the veggies within the chicken breasts. They can be incorporated into the dish later.

7. Transfer the skillet to your preheated oven and bake for 15-20 minutes or until the internal temperature of the thickest part of the breast registers 165 degrees.

8. Meanwhile, add the white American cheese and milk to a small saucepan over medium heat. Stir occasionally, until fully melted and combined then reduce heat to low.
