Easy Oven Fajitas

$7.78 recipe / $1.95 serving

Ooo, these are my new favorite thing!!

I love fajitas, but have had a hard time replicating their smoky goodness at home. I don’t have a grill or a cast iron griddle, so it’s been difficult to achieve that authentic fajita flavor. I’ve seen this oven method around the interent a lot lately, so I thought I’d give it a shot. SO glad I did!!!

Roasting the meat and vegetables in the oven gives them a slightly charred edge and a hard to replicate sweetness that you just can’t get in a plain old skillet. Even better yet, you don’t have to stand over the stove and babysit it while it cooks! Set it and forget it! YES. (can you tell how excited I am about this?)

I went with a vegetable heavy mix to keep costs low. I specifically used more green bell pepper and onion than anything else, because these are the two least expensive vegetables. I only used one small chicken breast (probably about 3/4 lb.) and sliced it very thin. The meat to veggie ratio was perfect after everything had cooked down. If you want to make this vegetarian, try using sliced portabello mushrooms in place of the chicken.

I like to keep my fajitas simple, with just a splash of lime, a few cilantro leaves, and a dollop of sour cream. I find that the lime really makes the flavors pop, but the other toppings are completely up to you! Play with it! :)

Oh, and although the ingredient list may look long, most of that is the fajita seasoning mix. If you want, you can just buy a packet of fajita seasoning instead, although they’re charging you a great deal for the simple act of stirring spices together!

  1. Preheat the oven to 400 degrees. Mix all of the ingredients for the fajita seasoning in a small bowl and set aside (chili powder, paprika, onion powder, garlic powder, cumin, cayenne pepper, sugar, salt, and corn starch).
  2. Cut the onion and bell peppers into ¼ to ½ inch wide strips. Place them in a large 9×13 inch casserole dish. Slice the chicken breast into very thin strips and add it to the casserole dish with the vegetables.
  3. Sprinkle the seasoning over the meat and vegetables. Drizzle the vegetable oil over everything and then use your hands to toss the ingredients until everything is well coated in oil and seasoning. Bake in the preheated oven for 35-40 minutes, stirring once half way through. Squeeze the juice from half of the lime over top of the meat and vegetables after it comes out of the oven.
  4. Scoop a small amount of meat and vegetables into the center of each tortilla. Top with a few sprigs of cilantro, a dollop of sour cream, and an extra squeeze of lime if desired.
*I buy my chicken breast when it’s on sale for $1.99/lb. and freeze it.

Step By Step Photos

fajita seasoningFirst mix together your fajita seasoning (chili powder, paprika, onion powder, garlic powder, cumin, cayenne pepper, sugar, salt, and corn starch). The corn starch helps keep things from getting too juicy while roasting and will help the seasoning adhere.

vegetablesThese are the vegetables that I used. I made sure to use more of the green bell peppers and onions because they are far less expensive than the red bell pepper.

cut vegetablesCut all of the vegetables into strips and place them in a large 9×13 inch casserole dish.

slice chickenAlso cut the chicken into very thin strips. My chicken breast was actually pretty small, but once everything was cooked and the vegetables had shrunk up a bit, the meat to veggie ratio was very good.

seasonAdd the chicken to the casserole dish with the vegetables. Sprinkle the fajita seasoning over top and drizzle with the vegetable oil. Use your hands to toss the ingredients together until they are well coated in spices and oil.

roast fajitasPop the casserole dish in a preheated 400 degree oven and let it roast for 35-40 minutes. Stir once half way through baking. Squeeze some lime juice over top after it comes out of the oven for an added zing.

  1. Allison says:

    Turned out great! Used boneless skinless chicken thighs since that was on sale and cooked everything on the grill since it’s summer and we don’t have a/c.

  2. Nikki says:

    I made these on the BBQ tonight, in a foil pan. They were AMAZING. They tasted just like restaurant fajitas. Fantastic!

  3. Jennifer says:

    These are so amazing that I even dreamt about them (true story!). They are now included in our regular rotation. They are even better than I expected them to be!

  4. Jenny says:

    Can you Substitute beef for this recipe?

  5. Jojo says:

    This was so good! I didn’t add the sugar but yummy!!!

  6. Susie says:

    Delicious and so easy!

  7. Michelle says:

    This recipe is awesome! My new go to fajita recipe. Thanks for sharing!

  8. Trish says:

    Made these tonight and they were fabulous. However, husband bought corn tortillas instead of flour tortilla and let me tell you, we won’t make that mistake again. The corn tortillas break really easily. Other than that, fabulous!

    • William says:

      While they do break apart easier than flour tortillas, I find they taste much better, not to mention they are typically cheaper and healthier. To each their own I guess. Regardless, this recipe goes great with any kind of tortilla, or none at all!

  9. Shelly says:

    Thank you for the step by step directions. This has become a very favorite for our family. :-) My only change is to omit the sugar (although it does caramelize the onions), double the cayenne pepper, and use extra virgin olive oil. This is an amazing dinner.

  10. Kristi says:

    This was sooooo good! I used coconut oil and left out the cayenne. Loved it and it was so easy!

  11. PERFECTION!!!! My bf and I made this for dinner tonight & boy oh boy was I surprised how delicious and tasty this was. He hates bell peppers & absolutely loved it! I made a few substitutions of my own. Instead of the cumin and cayenne peppers (bc we didn’t have it on hand), we used 1/2 tsp of crushed red peppers and opted not to use the cilantro. So glad I we found your recipe on Pintrest :) will definitely be looking for and using more of your recipes! Thank you

  12. Diane says:

    I made these last week! They were delicious! Great for my diet too!

  13. Nichole says:

    I made these over the weekend and they were fantastic! I will definitely be making these again and again. :)

  14. diane says:

    I have doubled the recipe for a college crowd for dinner. I used my turkey roasting pan to mix everything together. Do you recommend using 2 shallower pans for the oven? Or just use the roasting pan, and stir a couple of times? Any adjustments to time or temperature? (Also serving your Cilantro Rice and Spicy Black Beans.) Thanks!

    • I would suggest two shallower pans because they allow for more evaporation of the liquid. If too much liquid gets trapped the ingredients will sort of “stew” together.

  15. Brianne says:

    Made this last night, WHERE HAVE I BEEN ALL OF MY LIVE?! This was so delicious. I will be making this more often!

  16. Found this on Pinterest, and thought I would pop back on to the page to give credit where it is due. I made this last night, and my husband and I loved it! Delicious! I actually just grabbed a fajita seasoning packet (having a newborn, it was just easier), cut up all the veggies and chicken, mixed it all together and threw it in the oven. It’s nice having something new and yummy:) Thank you!

  17. Lindsey says:

    These are so good! I’ve made them twice. I have followed the spice mixture to a T, minus the sugar. It is a great use of the left over bits of veggies I have in the fridge. Thank you!

  18. Made these last nite~they will forever be my go to jita recipe! Thank you, Thank You!!

    Most delicious.
