This lemon herb chicken recipe is perfect for beginners. It’s simple, time-efficient, and healthy, relying on fresh ingredients and basic seasoning to create something that tastes truly special. You’ll love how everything roasts together on one pan, saving both time and cleanup.

Why This Recipe is Special

Sheet pan chicken fajitas are more than just convenient—they’re customizable, colorful, and incredibly satisfying. By baking everything in one layer, you get perfectly cooked chicken with slightly charred edges, caramelized vegetables, and all the bold flavors of traditional fajitas. Whether you’re cooking for your family or just for yourself, this quick and healthy meal is an absolute lifesaver.

Ingredients and Preparation

Chicken: The star of the dish. Chicken breast is lean, quick to cook, and soaks up flavor well. You can also use boneless thighs for a juicier texture.
Bell Peppers: Use a mix of red, yellow, and green for sweetness and vibrant color. They caramelize beautifully in the oven.
Onions: Essential for that signature fajita aroma and a touch of sweetness once roasted.
Olive Oil: Helps everything roast evenly and adds healthy fats.
Lime Juice: Brightens the flavor and acts as a tenderizer for the chicken.
Seasonings: A blend of chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and black pepper. These spices give the dish a classic Tex-Mex kick without needing a store-bought mix.
Tortillas: Flour or corn tortillas are both great options. Warm them up for the best texture.

Optional Add-ons: Fresh cilantro, sour cream, guacamole, pico de gallo, shredded cheese, and lime wedges all enhance flavor and texture.

Substitutions:

• Swap chicken for shrimp (reduce cooking time).
• Use tofu for a vegetarian version.
• Try frozen peppers and onions (thawed and patted dry) if you’re short on time.
• Greek yogurt can replace sour cream for a healthier topping.

Step-by-Step Instructions

Step 1: Preheat your oven to 425°F (218°C) and line a large sheet pan with parchment paper or foil for easier cleanup.

Step 2: Slice the chicken breasts into ¼-inch strips and cut the bell peppers and onions into evenly sized slices. Uniform size helps everything cook evenly.

Step 3: In a small bowl, mix together your fajita seasoning: chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and black pepper.

Step 4: Place the sliced chicken and vegetables on the sheet pan. Drizzle with olive oil and freshly squeezed lime juice.

Step 5: Sprinkle the seasoning mixture over the chicken and veggies. Use your hands or tongs to toss everything together until well coated, then spread it all into a single layer without overlap.

Step 6: Bake in the preheated oven for 20 to 25 minutes. Stir halfway through to promote even roasting. The chicken is done when it reaches an internal temperature of 165°F and has lightly golden edges.

Step 7: For extra flavor and a charred finish, place the sheet pan under the broiler for 2 to 3 minutes at the end.

Step 8: While the fajitas bake, warm your tortillas in a skillet, oven, or microwave.

Step 9: Serve hot, letting everyone build their own fajitas with their favorite toppings.

Beginner Tips and Notes

• Dry Your Chicken: Patting the chicken dry helps it brown instead of steam.
• Don’t Overcrowd: If ingredients overlap, they’ll steam instead of roast. Use two pans if needed.
• Preheat the Pan: Want an extra sizzle? Pop the empty sheet pan in the oven as it preheats.
• Even Cutting: Uniformly sized pieces cook at the same rate, preventing undercooked or burnt bits.
• Watch the Broiler: Keep an eye on it during the final minutes—things can go from charred to burned fast.

If your veggies overcook, reduce oven temperature slightly or slice them thicker. If your chicken browns too quickly, tent with foil midway through baking. No lime? A splash of vinegar adds similar brightness.

Serving Suggestions

• Low-Carb: Serve over cauliflower rice.
• Bowl Style: Layer with rice, beans, and toppings for a hearty meal.
• Lettuce Wraps: Use large romaine or iceberg leaves for a lighter twist.
• Toppings: Guacamole, shredded cheese, sour cream, chopped cilantro, or a squeeze of lime take it up a notch.

Leftovers:

• Store in an airtight container for up to 4 days.
• Keep tortillas separate to avoid sogginess.
• Reheat in a skillet for the best texture—microwaving can make the chicken rubbery.
