Tex-Mex Sheet-Pan Chicken Fajita Bowls
DINNER
A classic fajita spread is a theater of sizzling cast iron, grease-splattered stovetops, and an avalanche of chopping. We don’t have time for the theater, and your gut doesn't have the patience for the onions. By throwing everything onto a screaming-hot sheet pan, the active prep drops to ten minutes while the oven does the heavy lifting. The result is perfectly charred chicken, tender peppers, and deep, earthy Tex-Mex flavor layered over bright cilantro-lime rice. It's built strictly within Monash safety thresholds, so you can enjoy a Tuesday night dinner without dreading Wednesday morning.
Ingredients
- boneless skinless chicken breast or thighs10 oz
- green bell pepper75 g
- red bell pepper43 g
- scallion greens1/2 cup
- garlic-infused oil2 tbsp
- fresh lime juice1 tbsp
- ground cumin1 tsp
- smoked paprika1 tsp
- dried oregano1/2 tsp
- chili powder1/4 tsp
- kosher salt1/2 tsp
- pre-cooked white or brown rice1 1/2 cup
- fresh cilantro1/4 cup
Method
- 01
Preheat the oven to 425°F and line a large rimmed baking sheet.
Parchment paper or aluminum foil makes cleanup practically frictionless.
- 02
Place the chicken, peppers, and scallions on the pan, dress with the oil, lime, and spices, and toss to coat.
Use your hands or a pair of tongs. Make sure the meat and vegetables are thoroughly slicked with the seasoned oil.
- 03
Spread the mixture into a single, uncrowded layer and bake for 15 to 18 minutes.
Overcrowding creates steam instead of char. Cook until the chicken is done and the edges of the peppers pick up some color.
- 04
Warm the pre-cooked rice and toss it with the chopped cilantro, a squeeze of lime juice, and a pinch of salt.
This knocks out a quick, bright arroz verde stand-in while the oven finishes working.
- 05
Divide the cilantro-lime rice between two bowls and crown with the roasted fajita mixture.
Serve immediately with extra lime wedges and any safe optional toppings like lactose-free sour cream.
Notes
Why this swap?
Traditional fajitas rely on onions and garlic, which pack a massive fructan payload. Fructans are water-soluble but insoluble in fat, so garlic-infused oil gives you the garlic punch safely, while scallion greens mimic the sharp, sweet flavor of roasted onions without triggering a flare.
The bell pepper math.
Monash updated their thresholds in 2022, confirming green peppers contain fructans while red peppers contain fructose. Because they belong to different carbohydrate subgroups, we can safely combine 75g of green and 43g of red in one pan without stacking our triggers.
Gut Irritant Warning: Capsaicin.
Chili doesn't contain FODMAPs, but capsaicin can still irritate a flared-up gut. Scale the chili powder back or omit it entirely in favor of extra smoked paprika if your system is currently in high-alert mode.
