Ingredients

Ingredient Notes

Chicken breasts – I recommend chicken breasts specifically for these oven baked fajitas and not chicken thighs. The recipe calls for 1.5lbs of chicken breasts, but up to 2lbs of chicken will work.

Clean food tip: I prefer to buy organic chicken - this means that the chickens were fed organic feed and not given any antibiotics. If organic isn’t an option for you, don’t shy away from conventional chicken –it still tastes great and works perfectly in this recipe.

Bonus points if you can also find chicken that has an animal welfare certification like “Animal Welfare Approved”, “Certified Humane”, or “Global Animal Partnership”- these mean they follow a more rigorous standard around the chickens' living condition.

Sweet bell peppers – use any combination of red, yellow, or orange bell peppers.

Onion – I use a yellow onion, but you could use a sweet onion or even a red onion.

Seasoning mix – I highly recommend using my homemade taco seasoning for these oven baked fajitas (it is so easy to whip together), but you can easily use a packet of seasoning. If using store-bought, use 2 packets of seasoning.

Tapioca - used to help create a sauce for the fajitas. You can use arrowroot or corn starch in its place.

Step-by-Step Instructions

Step 1: Preheat oven to 400. Place sliced bell peppers and sliced onions in a 9x13 baking dish. Push peppers/onions off to the sides and place the chicken breasts flat on the bottom of the dish. Drizzle the chicken and bell peppers/onion with 2 TBSP extra-virgin olive oil and sprinkle dish with the seasoning.

Step 2: Bake for 25-30 minutes. If chicken is not at 165 at this time, continue baking until chicken breasts are cooked. Stir peppers half way through to ensure even cooking.

Tip: while the chicken and veggies are cooking, prepare any toppings you want for your fajitas or fajita salads\bowls.

Step 3: After chicken has cooked, remove from baking dish and shred with 2 forks. Return shredded chicken back to baking dish and mix together with bell peppers and onions.

Now you can enjoy this easy fajita recipe for dinner.

Recipe FAQS

Can I use store-bought seasoning instead of homemade?

For sure! If buying store bought, you can either buy taco seasoning or fajita seasoning - use 2 packets of seasoning if using store-bought.

How far in advance can this be made?

You can prep this fajita bake up to 48 hours in advance and store covered in the fridge until ready to bake. Or you can even bake ahead of time, store covered in the fridge, and re-heat throughout the week. It's perfect for meal prep!

Notes

Chicken breasts: I use roughly 1.5lbs of chicken in this recipe. This is typically 2-3 chicken breasts. Total cooking time will vary pending the size of your breasts. If you’re chicken breasts are on the smaller side and cook quicker than the peppers, you can remove them from the dish and shred and add back once the peppers are done cooking.

Mix peppers: Mix the bell peppers and onions half way through baking time to ensure even cooking.
