2022 changes: Ingredient adjustments were made to this recipe to reflect the current low FODMAP serving sizes after Monash University retested some popular foods.
These FODMAP-friendly chicken fajita bowls use low FODMAP garlic and onion substitutes, like garlic-infused olive oil and green onion tops, as well as a low FODMAP taco seasoning, to add Tex-Mex flavor without all of the FODMAPs.
To make things even easier – I see you, busy FODMAPing friend – this recipe calls for just nine flavor-packed ingredients, is baked on a single sheet pan, and can be ready in about 30 minutes.
Are fajitas low FODMAP?
Although delicious, classic fajita recipes usually feature high FODMAP ingredients like onion and garlic and are therefore not recommended when following the low FODMAP diet for IBS.
To make these yummy low FODMAP chicken fajita bowls, you’ll want to grab the following nine ingredients:
- Low FODMAP taco seasoning (I use Fody Foods Low FODMAP Taco Seasoning or make my own) – 2 teaspoons
- Lime – about 1 medium to yield 2 tablespoons of juice
- Garlic-infused olive oil – 2 tablespoons
- Green bell pepper – 1.5 medium
- Red bell pepper – ½ medium
- Boneless, skinless chicken thighs – 1 to 1.25 pounds
- Brown rice – 2 cups cooked (To save time, I like to use instant brown rice like Minute or a frozen microwaveable option like Birdseye Steamfresh)
Low FODMAP notes
In this section, I share information for ingredients that are either frequently asked about or have suggested serving sizes to remain low FODMAP. We each have unique tolerance levels and nutritional needs. Please listen to your body (and, if possible, work with a FODMAP-trained dietitian) to determine what is best for you. For more low FODMAP serving size info, please refer to the Monash FODMAP app and FODMAP Friendly website or app.
Low FODMAP taco seasoning is an easy way to add flavor to low FODMAP dishes. Many store-bought taco seasonings contain high FODMAP onion or garlic. Instead, I use Fody Foods Taco Seasoning (certified low FODMAP by Monash University) or make my own.
Lime juice is low FODMAP in servings up to 1 cup or 250 grams.
Garlic-infused oil is a popular way to add low FODMAP garlic flavor on the low FODMAP diet. My current favorite is Colavita Roasted Garlic Olive Oil (technically a garlic-flavored oil) that Monash University has confirmed to be low FODMAP. Learn more about why garlic-infused oil is okay in my Low FODMAP Garlic and Onion Substitutes post.
Red bell pepper
is a FODMAP-free food. 2022 Update: Monash University retested red bell pepper and found it to contain FODMAPs. A low FODMAP serving of red bell pepper is now considered to be ⅓ cup or 43 grams. Larger servings contain moderate to high amounts of excess fructose. Peppers and chili peppers also contain capsaicin, which can be a non-FODMAP trigger for some people. Avoid if you suspect spicy food is an issue.
Green bell pepper is low FODMAP in ½ cup or 75-gram servings. Larger servings contain higher amounts of fructan.
Gather and prep ingredients – or as the French say “mise en place.” Taking the time to gather and prep ingredients at the beginning may lead to a smoother, more enjoyable cooking experience. 🙂
Preheat the oven to 425°F. Coat a large sheet pan with nonstick cooking spray.
Whisk. In a large bowl, whisk together taco seasoning, lime juice, and garlic-infused oil.
Toss. Add bell pepper slices and chicken pieces. Toss until the chicken and peppers are evenly coated with seasoning.
Spread the chicken and veggie mixture onto the prepared sheet pan, arranging in a single even layer.
Bake for 8 minutes. Stir the chicken and pepper slices. Then, bake for an additional 7-8 minutes or until the chicken is cooked and the veggies are fork-tender.
Serve warm over cooked brown rice. Garnish with optional green onion tops (green parts only), cilantro, and lime wedges.
