Absolutely, just adjust the amounts to the appropriate size for your needs.
When you remove the sheet pan from the oven, squeeze some fresh lime juice over the entire pan and add some chopped cilantro to add a fresh taste and wake up the flavors.

Expert Tips for Making Sheet Pan Chicken Fajitas
- Different proteins. Feel free to swap out the chicken thighs for any protein you like. Depending on what you choose, you may have to adjust the cooking time, though.

Thanks for this simple, delicious recipe! It’s great for my family because my husband is on a low carb diet. He can just skip the tortilla and eat the rest of it.

Will you put back the baked fajita recipe? I make it weekly. You’d think I’d know it by heart after all this time but I always refer to the recipe. I’m distraught to see it replaced with the sheet pan fajita recipe.
It’s pretty much the same recipe — just add a can of diced tomatoes to the pan. 🙂
I was wondering if I need to cook the chicken partially or completly before adding the vegetables to it? Also can this be done in crock pot instead of oven? Thanks:)
I bake everything together in the oven. I don’t partially cook the chicken first.

I’m sure it could…I’ve never tried it though.
Yum. I hadn’t thought of chicken instead of Hamburg. This one might have to be on a future dish.
