Ingredient Notes

Ingredients used to make Fajita Stuffed Chicken.
  • Boneless Skinless Chicken Breasts: Thick ones are perfect so you can butterfly them. If they are thin, you’ll want to just pound them out to an even thickness. You can also buy chicken that’s already butterflied at many grocery stores.
  • Olive Oil: You can use any neutral cooking oil like avocado or vegetable oil as well.
  • Mushrooms: Either white or cremini works here, depending on your preference.
  • Bell Pepper: We like to use a mixture of red and green for color and flavor since red have a little bit of sweetness.
  • Onion: White or yellow onions will work here.
  • Pepper Jack Cheese: We like to bring the flavor and the heat here. Monterey jack would be the second-place choice.
  • Lime Juice: Fresh limes are best, and you’ll need about two for this recipe. Bottled lime juice will also work.
  • Fajita Seasoning: Store-bought Fajita seasoning works well. We like making our own so we can better control the flavor.
  • Red Pepper Flakes: Adds a subtle heat, which you can adjust according to your preference.

Fajita Seasoning

While you can find pre-made fajita seasoning in pretty much any grocery store, we recommend making your own! Each brand differs in its ratios and quality of spices, so using our spice mix will ensure you get the flavor results as intended. It only takes a few extra minutes.

Red pepper flakes: Another pro of making your own spice mix is that you can control the spice level—if your family isn’t as spice tolerant, you can reduce the amount of red pepper flakes you add in. Or, if you’re really looking for some heat, feel free to add more!

Methods for Stuffing Chicken

In order to stuff a chicken breast, you have to either cut it open or pound it out thin. You can buy chicken already butterflied at some grocery stores, but the real issue is that chicken breasts vary a lot in thickness. Here’s what you do based on the chicken that you have.

Butterfly Method (For Thick Chicken Breasts): This is the most common method for stuffing chicken breasts. You simply slice the chicken horizontally, stopping just before cutting it all the way through on the back side. When you open it up, it looks like butterfly wings. This works best when the chicken breast is plump and thick.

Pounding Thin (For Thin Chicken Breasts): If your chicken breasts are already on the thin side, you can place them between two sheets of plastic wrap or parchment paper and use a meat mallet (or even a rolling pin) to pound them to an even thickness. This gives you a flat surface that’s easy to roll up around the stuffing. Just be careful not to over-pound, or the chicken may tear.

Make it a Meal

Veggies and salad are great options. You could serve it with Mexican rice or even plain steamed rice. You could even get a little fancier with some delicious Mexican street corn salad or go with what they call “cowboy caviar” and make black bean and corn salad.
