Ingredient Notes & Details

Flank Steak or Skirt Steak
These cuts are ideal for fajitas because they cook quickly and stay tender when sliced properly. Always slice against the grain for maximum tenderness. You can substitute sirloin if needed for a budget-friendly baked steak recipe option.

Bell Peppers
Use a mix of red, yellow, and green for vibrant color and sweetness. Oven roasted bell peppers develop incredible flavor as they caramelize. Slice them evenly so they roast at the same rate.

Yellow Onion
Adds sweetness and depth. Red onion can also be used for a slightly sharper flavor. Slice thick enough to avoid burning.

Olive Oil
Helps the steak and vegetables roast evenly and prevents sticking. Avocado oil works well too, especially at higher oven temperatures.

Chili Powder
The base of fajita seasoning. Choose a high-quality chili powder for bold flavor.

Smoked Paprika
Adds depth and subtle smokiness. This enhances the oven roasted steak flavor beautifully.

Ground Cumin
Brings warmth and authentic Tex-Mex flavor.

Garlic Powder
Adds savory richness without overpowering.

Salt and Black Pepper
Essential for bringing all the flavors together.

Fresh Lime Juice
Brightens the finished dish and balances the richness of the steak.

Optional Toppings
Shredded cheese for a cheesy steak side dish twist, sour cream, guacamole, pico de gallo, fresh cilantro, and warm tortillas.

Step-by-Step Instructions

Preheat the Oven
Preheat your oven to 425°F. A hot oven is key for achieving caramelization and those slightly crisp edges on the steak and vegetables.

Prepare the Steak
Pat the steak dry with paper towels. This helps it brown instead of steam. Slice it into thin strips against the grain. Look closely at the muscle fibers — cutting across them ensures tender bites.

Slice the Vegetables
Cut the bell peppers into even strips. Slice the onion thick enough so it softens and caramelizes without burning.

Season Everything
In a large bowl, toss the steak and vegetables with olive oil. Add chili powder, smoked paprika, cumin, garlic powder, salt, and black pepper. Toss until evenly coated. Every piece should glisten with seasoning.

Spread on the Sheet Pan
Arrange everything in a single layer. Do not overcrowd. If needed, use two pans. Overcrowding prevents proper roasting and leads to steaming.

Bake Until Caramelized
Roast for 18–22 minutes. Halfway through, gently stir everything to ensure even cooking. The steak should be browned at the edges, and the peppers should look softened with slight charred spots.

Finish with Lime
Remove from the oven and squeeze fresh lime juice over the top. This brightens the entire dish and balances the savory seasoning.

Rest Before Serving
Let the steak rest for about 5 minutes before serving. This allows the juices to redistribute for maximum tenderness.
