Easy oven baked chicken fajitas are a quick yet delicious meal idea suitable for busy weeknights or stress-free weekend meals.

Mexican meals are probably some of my favorite meals. There’s nothing like chips and cheese dip and homemade guacamole to make me feel like throwing a fiesta. Going out for dinner is just not on the agenda some nights.

That’s where these wonderful, easy oven baked chicken fajitas come in. Just a few minutes of prep and about 20 minutes of baking and you have a delicious meal that everyone in the family will love.

Being carb conscious while having a love of Mexican can be hard. Luckily, these fajitas are great in a bowl on top of some lettuce, or wrapped up in tortillas.

Easy recipes are so important to me because they give me time to concentrate on more important aspects of my life, like vegging out in front of the TV watching American Pickers.  This could almost be considered a “fix it and forget it” meal because you just cut up veggies, cut up meat, throw it in a baking dish with some seasoning and oil and let it cook.  

30ish minutes later, you have a delicious meal that’s easily customizable (looking at you, tiny humans who don’t eat peppers.  Or onions.)

Oven baked chicken fajitas before baking

This is seriously such an easy dinner idea.

I’ve been making this meal for years, and have never had it turn out poorly.  If you have a great homemade taco seasoning recipe like I do, then you’re even better off because you get a healthy meal without a load of unhealthy additives.  

There are also some lower carb tortilla options that give you added fiber.  For those of you that do a strict low-carb or keto diet, you know how important fiber is for your carb count 🙂 These tortillas are awesome for that, FYI.

Making easy, oven baked chicken fajitas is easy. Really, really easy.

First, preheat the oven to 400 degrees. Then cut up the onion and peppers in 3/4 inch slices. Cut the chicken into slices of equal thinkcness, about 3/4 an inch.

Mix it all in a bowl with the oil (either EVOO or vegetable) and the taco seasoning. Pour the mixture into a 9×13 baking dish and cook for 20 minutes.

Serve on tortillas or lettuce for a low carb option. Top with sour cream, avocado, salsa or whatever mexican side your heart desires.

If I am low carbing, I serve this over lettuce with a side of cauliflower “rice” topped with cheese.

cooking steak is easy in the oven too

I recently made these with baked chicken and steak. I was surprised by how well the steak came out. I seared it in the frying pan with oil for a couple of minutes (only on one side) then baked it in the oven along with the chicken for the full 20 minutes.

The only complaint I had with the oven baked steak fajitas was that the steaks were medium. Hubs and I are more medium-rare steak connoisseurs. The flavor and tenderness of these steaks made up for it.
