Step-by-Step Instructions:
1. Prepare Your Steak and Vegetables
Preheat your oven to 400°F (200°C). Slice your flank steak thinly against the grain for tenderness. Then, core and slice your bell peppers and onion into thin strips.
2. Season Everything Together
In a large bowl, combine the sliced steak, bell peppers, and onion. Drizzle with olive oil and sprinkle with fajita seasoning. Toss everything together until thoroughly coated.
3. Arrange on the Sheet Pan
Spread the seasoned steak and vegetables in a single layer on a large baking sheet. Make sure not to overcrowd the pan; this helps everything cook evenly and get a nice char.
4. Bake to Perfection
Bake for 15-20 minutes, flipping once halfway through, until the steak is cooked through and the vegetables are tender-crisp. For a little extra char, you can broil for the last 1-2 minutes, watching carefully.
5. Serve Your Homemade Dinner
Remove the sheet pan from the oven. Squeeze fresh lime juice over the fajitas and sprinkle with fresh cilantro, if using. Serve immediately with warm tortillas and your favorite toppings for a fantastic homemade dinner.
Variation Ideas:
- Add sliced jalapeños for an extra kick.
- Include sliced zucchini or mushrooms with the bell peppers.
- Try a different protein, like shrimp or firm tofu, adjusting cook time as needed.
