The blend of roasted vegetables and seasoned chicken creates a restaurant-style fajita experience right at home. Using plain Greek yogurt keeps the toppings creamy without overpowering the fresh cilantro and bright lime.

Ingredients

• ▢¾ cup diced roma tomatoes
• ▢½ yellow onion sliced
• ▢2 bell peppers any color, sliced
• ▢¼ cup plain Greek yogurt
• ▢1 ounce fajita seasoning store-bought or homemade
• ▢1 tablespoon minced fresh cilantro
• ▢2 boneless, skinless chicken breastscut into strips
• ▢8 medium flour tortillas
• Optional Garnishes: queso fresco, cilantro, lime, and greek yogurt

Equipment

• Large rimmed baking sheet
• Mixing bowls
• Tongs or spatula
• Knife and cutting board
• Aluminum foil or parchment paper (optional for easier clean-up)

Prep at a glance

Preheat your oven while you slice the vegetables and chicken, and gather the yogurt and cilantro so assembly is quick. The fajita seasoning—whether store-bought or homemade—does the heavy lifting for flavor, so be generous and even across the chicken and vegetables.

Step-by-step Directions

1. Preheat the oven to 425°F (220°C). Line a large rimmed baking sheet with aluminum foil or parchment if you prefer easier cleanup.
2. Place the 2 boneless, skinless chicken breasts cut into strips in a medium bowl. Sprinkle the 1 ounce fajita seasoning evenly over the chicken. Use tongs or your hands to toss the chicken so each strip is coated with the seasoning.
3. Arrange the seasoned chicken strips in a single layer on one half of the prepared baking sheet, leaving space for the vegetables.
4. In a separate bowl, combine the ▢½ yellow onion sliced and the ▢2 bell peppers any color, sliced. Sprinkle any remaining fajita seasoning over the vegetables if you have a little left—or add a light drizzle of oil and a small pinch of the seasoning to the vegetables. Toss to coat and spread the vegetables in a single layer on the other half of the baking sheet, keeping them slightly apart from the chicken so everything roasts evenly.
5. Roast the chicken and vegetables in the preheated oven for 16–20 minutes, flipping the chicken and stirring the vegetables about halfway through. The chicken should register 165°F (74°C) and the vegetables should be tender with lightly charred edges.
6. While the sheet pan is in the oven, make the cilantro-yogurt sauce. In a small bowl, stir together the ▢¼ cup plain Greek yogurt and ▢1 tablespoon minced fresh cilantro. Taste and add a pinch of salt or a squeeze of lime if you like brightness.
7. Remove the baking sheet from the oven. Allow the chicken to rest for 3–5 minutes, then slice any thicker pieces as needed into bite-sized strips.
8. Warm the ▢8 medium flour tortillas in the oven for 1–2 minutes on a clean sheet, or wrap them in foil and heat for 5–8 minutes. Keep them covered so they stay pliable.
9. Assemble the fajitas: spoon roasted chicken and vegetables onto warm tortillas, add a few spoonfuls of ▢¾ cup diced roma tomatoes, and top with a dollop of the cilantro-yogurt. Garnish with optional queso fresco, extra cilantro, and lime wedges to squeeze over the top.
10. Serve immediately, and enjoy!

Notes & tips

• Cook time: Ovens vary. Check the chicken for an internal temperature of 165°F (74°C) to ensure it’s cooked through but still juicy.
• Vegetable variations: Use any color bell peppers you prefer; red and orange tend to be sweeter while green gives a slightly earthier flavor.
• Seasoning swap: If your fajita seasoning is very salty, use slightly less and adjust after tasting the roasted components.
• Make it dairy-free: Substitute the plain Greek yogurt with a thick nondairy yogurt alternative if you need a dairy-free option; the cilantro still brightens the sauce.
• Crispier edges: Broil for 1–2 minutes at the end of roasting if you want more char on the vegetables—watch closely to avoid burning.

Serving suggestions

These Sheet Pan Chicken Fajitas (For Two!) are delicious with a simple side salad, a scoop of cilantro-lime rice, or a bowl of black beans. Leftovers make great meal prep; store chicken and vegetables separately from tortillas and reheat in a skillet for best texture.

Make-ahead & storage

Store cooled chicken and vegetables in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat to preserve texture. Keep tortillas wrapped separately at room temperature; if storing longer, place them in an airtight container in the fridge and warm before serving.

Quick variations

• Double the vegetables for a lighter protein-to-veggie ratio and more colorful plates.
• Swap the chicken strips for sliced turkey breast for a different lean protein option using the same seasoning and bake time.
• Add a handful of sliced jalapeños to the sheet pan for a touch of heat.

Final thoughts

These Sheet Pan Chicken Fajitas (For Two!) deliver juicy, well-seasoned chicken and roasted vegetables with minimal fuss. The cilantro-yogurt adds a creamy, herbaceous counterpoint, and simple garnishes like queso fresco and lime bring brightness to each bite. Perfect for a cozy dinner for two or an easy weekend meal that feels special without the effort.
