* **1/2 Teaspoon Onion Powder:** Complements the garlic powder and adds a balanced flavor.
* **1/4 Teaspoon Smoked Paprika:** Adds a smoky flavor that elevates the dish.
* **Salt and Black Pepper:** To taste. Adjust according to your preferences.

* Pickled Onions
* Jalapeños (fresh or pickled)

## Equipment You’ll Need

* **Large Sheet Pan:** A large sheet pan (12×17 inches) is essential for evenly distributing the fish and vegetables.
* **Parchment Paper or Aluminum Foil (Optional):** Lining the sheet pan with parchment paper or aluminum foil makes for easier cleanup.
* **Cutting Board and Knife:** For prepping the vegetables.
* **Mixing Bowls:** For tossing the vegetables and fish with the seasonings.
* **Spatula:** For flipping the fish and vegetables during cooking.

## Step-by-Step Instructions

1. **Preheat the Oven:** Preheat your oven to 400°F (200°C). Make sure your oven rack is positioned in the center.

2. **Prepare the Vegetables:** Wash and dry all the vegetables. Slice the bell peppers into strips, the red onion into wedges, and the poblano pepper (if using) into thin slices. Add the sliced vegetables to a large mixing bowl.

3. **Season the Vegetables:** Drizzle the vegetables with 1 tablespoon of olive oil, then sprinkle with 1/2 tablespoon of taco seasoning, 1/4 teaspoon of chili powder, 1/4 teaspoon of garlic powder, 1/4 teaspoon of onion powder, and a pinch of salt and pepper. Toss well to ensure the vegetables are evenly coated. Spread the vegetables in a single layer on the prepared sheet pan.

4. **Prepare the Fish:** Pat the fish fillets dry with paper towels. This helps them to brown better in the oven. Place the fish fillets in a separate mixing bowl. Drizzle with the remaining 1 tablespoon of olive oil. Sprinkle with the remaining 1/2 tablespoon of taco seasoning, 1/4 teaspoon of chili powder, 1/4 teaspoon of garlic powder, 1/4 teaspoon of onion powder, 1/4 teaspoon of smoked paprika, and a pinch of salt and pepper. Gently toss to coat the fish evenly.

5. **Arrange the Fish on the Sheet Pan:** Arrange the fish fillets on the sheet pan with the vegetables, leaving some space between them for even cooking. Make sure the fish isn’t overcrowded. If necessary, use two sheet pans.

6. **Bake:** Bake for 12-15 minutes, or until the fish is cooked through and flakes easily with a fork. The exact cooking time will depend on the thickness of the fish fillets. Check for doneness around the 12-minute mark. The internal temperature of the fish should reach 145°F (63°C).

7. **Warm the Tortillas:** While the fish and vegetables are baking, warm the tortillas. You can do this in a dry skillet over medium heat, in the microwave, or wrapped in foil in the oven.

8. **Assemble the Tacos:** Once the fish and vegetables are cooked, remove the sheet pan from the oven. Flake the fish into smaller pieces with a fork. To assemble the tacos, place some fish and vegetables in a warm tortilla. Top with your favorite toppings and enjoy!

## Tips and Tricks for Perfect Sheet Pan Fish Tacos

* **Don’t Overcrowd the Pan:** Overcrowding the sheet pan will steam the fish and vegetables instead of roasting them. If necessary, use two sheet pans to ensure everything cooks properly.
* **Pat the Fish Dry:** Patting the fish dry before seasoning it helps it to brown better in the oven.
* **Adjust the Seasoning to Your Liking:** Feel free to adjust the amount of taco seasoning, chili powder, and other spices to suit your taste preferences.
* **Use Fresh Ingredients:** Using fresh, high-quality ingredients will result in the best flavor.
* **Warm the Tortillas:** Warming the tortillas makes them more pliable and flavorful.
* **Get Creative with Toppings:** Don’t be afraid to experiment with different toppings to find your favorite combination.
* **Add a Squeeze of Lime:** A squeeze of fresh lime juice brightens up the flavors of the tacos.
* **For Extra Flavor:** Consider marinating the fish for 30 minutes before baking. A simple marinade of lime juice, olive oil, and taco seasoning works well.
* **Broil for Extra Color:** For a more caramelized look and extra flavor, broil the fish and vegetables for the last 1-2 minutes of cooking time, keeping a close eye to prevent burning.

## Variations and Substitutions

* **Spicy Fish Tacos:** Add a pinch of cayenne pepper or a dash of hot sauce to the taco seasoning for a spicier kick.
* **Shrimp Tacos:** Substitute the fish with shrimp. Reduce the cooking time to 8-10 minutes, or until the shrimp is pink and opaque.
* **Chicken Tacos:** Use chicken breast or thighs instead of fish. Increase the cooking time to 20-25 minutes, or until the chicken is cooked through.
* **Vegetarian Tacos:** Omit the fish and add more vegetables, such as zucchini, corn, or black beans. You can also add tofu or tempeh.
* **Sweet Potato Tacos:** Roast cubed sweet potatoes with the other vegetables for a delicious and healthy twist.
* **Different Vegetables:** Feel free to substitute or add other vegetables, such as broccoli, cauliflower, or Brussels sprouts.
* **Different Fish:** Try using salmon, tuna, or swordfish for a different flavor profile.
* **Gluten-Free Tacos:** Use corn tortillas to make this recipe gluten-free.
* **Dairy-Free Tacos:** Omit the sour cream or cheese or use dairy-free alternatives.
