Substitutions and Variations

Use your favorite store-bought brand of fajita seasoning or my homemade recipe in the recipe card below. Taco seasoning will work too!

You can use fresh or frozen bell peppers for this stuffed pepper recipe. Either cut them in half or chop off the top of each pepper to stuff them.

While this recipe uses shredded chicken, you can use another type of meat if you prefer. Barbacoa would be tasty, steak fajita meat would work, and even ground beef.

If you’re not worried about sticking to Whole30, you can use regular rice instead of cauliflower rice.

Choose whatever type of cooked chicken you want for this meal! My Instant Pot chicken fajitas would be great, as well grilled chicken that has marinated Mexican chicken marinade. Store-bought chicken fajita meat or rotisserie chicken also works!

How to Make Chicken Stuffed Peppers

There are three stages to preparing this easy meal! Follow these step by step instructions to make stuffed bell pepper halves:

Prepare the Vegetables

Preheat your broiler and then cut the peppers in half lengthwise, remove the stems, and scoop out the seeds. Rub the insides and outsides with a little bit of olive oil, then place on a lined baking sheet.

Broil for 3-4 minutes per side, until softened slightly. If any char forms on the skin, allow the peppers to cool and then rub it off with your thumbs.

Dice the onion and mince garlic, then set it aside.

Prepare the cauliflower rice. I saute the frozen kind straight from a bag over low heat, stirring occasionally, until warmed and beginning to brown. Slice the lime and avocados.

Prepare the Chicken

Cut the tender chicken into bite sized pieces & season generously with salt and pepper.

Heat oil in a large skillet over medium heat, then add the chicken in, stirring occasionally. Once the chicken begins to brown, add the onion to the pan and sauté together for another 5 minutes.

Stir in the fajita seasoning and tomatoes and bring the mixture to a simmer. Allow it to cook together for about 2-3 minutes, then remove it from the heat.

Assemble the Stuffed Peppers

Spoon the chicken into the peppers with prepared cauliflower rice, your favorite salsa, sliced avocado, or any other toppings and enjoy!

How to Store Leftover Chicken Stuffed Peppers

Allow leftovers to cool and then transfer to an airtight container. Store in the fridge for 3-4 days. You can also freeze any leftover peppers! Just allow them to cool and wrap individually in plastic wrap or aluminum foil and then place in a freezer safe container. Freeze for up to 3 months. Thaw before reheating.

What to Serve with Chicken Stuffed Peppers

These hearty chicken stuffed peppers can be served on their own or with your favorite sides. Chips and salsa is always a good option. We also love Mexican rice and Mexican cauliflower rice.

If you wanna pack in some more veggies, then serve sides like air fryer brussels sprouts, air fryer frozen green beans, or roasted baby carrots. Some quick microwave broccoli would be easy too.

Toppings for Stuffed Peppers

There are so many different toppings that you can use with this easy stuffed peppers recipe! You can stick with Whole30 toppings or choose whatever you want. So, here’s a few fun ideas for this healthy meal:

sour cream or Greek yogurt
shredded cheese
black beans
salsa
salsa verde
guacamole
lime juice
green onion
Mexican corn or corn salsa
jalapeños
mango pico de gallo (pictured above)

Tips for Success

These few tips and tricks will help you achieve perfect success with this easy, low carb meal:

Need to save some time? Then use store-bought rotisserie chicken! Whole Foods and Fresh Market both offer Whole30 compliant rotisserie chicken, and I’d be willing to bet a lot of other grocers do too! Of course any leftover chicken or cooked chicken will work great.
Use frozen cauliflower rice. It will save you the hassle and mess of doing it yourself, and I also think it turns out great!
Try to choose bell peppers that are evenly shaped. Wonky peppers may be difficult to fill and cut into little boats for the chicken filling.

FAQ

How do you keep bell peppers from getting watery?

Pre-cooking the bell peppers is the best way to keep them from getting watery. This is why I pop the peppers under the broiler for a few minutes before stuffing them and baking.

Is it better to freeze stuffed peppers cooked or uncooked?

Freezing cooked leftovers is the best option. When you are ready to reheat, allow the peppers to thaw in the fridge overnight. Reheat in an oven until warm!
