Sheet Pan Chicken Fajitas

June 23, 2017

By Kath Dedon


Sheet Pan Chicken Fajitas was a hit at Chez Dedon last night! Bob declared that it was perfectly seasoned, and I had to agree.

I had saved Toni’s recipe from her Boulder Locavore blog to Pinterest. I ran across it again yesterday and decided to make it. Click on the link for her blog if you want to see the video she posted about the recipe. She used a gallon bag to marinate the ingredients, but I thought a bowl might be easier, so that’s what I used. You can refrigerate the ingredients to marinate for up to 24 hours or you can just let them marinate for the time that it takes your oven to preheat. We found the flavor was great even after a short marinating time.

Fajitas are traditionally served with hot flour tortillas. Toni uses corn tortillas to make it gluten free. She recommends wrapping tortillas in foil and putting them in the oven with the sheet pan for the last ten minutes .

I skipped the tortillas and served the Sheet Pan Chicken Fajitas over a bed of just-harvested lettuce from our yard. It made a great low-carb, main-dish salad for a warm night.

However you choose to serve them, I highly recommend Sheet Pan Chicken Fajitas! I topped ours with sliced avocado and a bit of sour cream for me. Other toppings that could be used might be guacamole, salsa, pico de gallo, or shredded cheese.

3. Put chicken in the bowl and stir the chicken and vegetables together well so the marinade is evenly distributed. At this point you can cover the bowl and refrigerate it for up to 24 hours. It will be good, though, with just 20 minutes time while the oven is heating.

5. Line a large baking sheet with aluminum foil.

6. Spread the ingredients out on the baking sheet.

    Yum! What a great idea to serve as a warm salad. We’ll have to try this one, but likely to use chicken thighs instead of breast. Now, if one could only find a carb free, low fat and low calorie tortilla life would be perfect.

      You know, I thought the same thing, Ron, that I would use chicken thighs next time. Great minds think alike!
