Why You'll Love These Chicken Fajitas

⭐ There's no pre-prepping or marinating needed and requires just 10 minutes of prep. You can even prep this in the morning, keep it in the fridge and then just cook it at night.

⭐ The chicken is oven baked on a sheet pan so that you can walk away and do other things while this is cooking. I love chicken tray bakes for this very reason!

⭐ All of the ingredients are super easy to find at the supermarket.

Ingredients For Sheet Pan Chicken Fajita Recipe

Capsicums or bell peppers - I used a pack of three colour capsicums.

Onions - 2 medium onions. Red, white or brown onions work.

Chicken - Boneless, skinless chicken fillets. Use thigh if you prefer your chicken a bit juicier or use breast or tenderloin if you prefer white meat.

Taco seasoning mix - I make my own so I always have a jar of this handy (and I've shared the recipe below) but there's no need to buy a specific fajita mix, you can use taco seasoning and my recipe below.

Soy sauce - This sounds crazy but soy sauce is one of the first ingredients of a fajita seasoning mix! It seasons and browns chicken but also tenderises it.

Sugar - A little white sugar just to balance the flavours and help the sauce caramelise.

Oil - I use extra virgin olive oil but you can use whichever oil you like.

Tortillas - Flour or corn tortillas, small or medium size. Flour tortillas are more pliable and soft and more often used for fajitas.

Tips For Making Sheet Pan Chicken Fajita Recipe

1 - These chicken fajitas are mild and not very spicy at all so they are good to feed a family. If you want to add more heat, add slices of fresh jalapeno to each wrap.

2 - Fajita seasoning mix is similar to a taco seasoning mix. The main difference for fajita seasoning mix is that it uses soy sauce or soy sauce powder! Seriously, take a look at the packet and that is the first ingredient. It helps to season, tenderise and colour the chicken.

3 - Covering the mixture with foil allows the chicken to steam and locks moisture in for the first half. The second half of cooking caramelises the chicken.

4 - Serving upgrade: make it feel like a restaurant by bringing it to the table in a sizzling cast iron dish!

5 - Other options for fillings to pair with the chicken and capsicum peppers: shredded lettuce, guacamole, spiced rice, pico de gallo salsa, grated cheese, tomatoes or refried beans.

Personal Note

Teddy is my little shadow whenever I slice up the chicken for these fajitas. Milo is allergic to chicken and somehow he seems to know that the chicken isn't for him so he doesn't always come when he smells this being prepared which honestly makes me a bit sad because I know that he has FOMO about everything.

My sister Blythe told me that my mother loves getting videos of Teddy and Milo and suggested that I send more videos. I said that I would so I've been sending her videos every second day. She watches them again and again and I think just seeing them is very exciting for her even if she won't get to see them again in real life.

The videos are not very long and it's basically me just talking to them but we make sure to put different clothes on them just to make it more interesting! And if you have any ideas how to make some cute dog videos please let me know!
