🧾 Ingredients
For the Fajitas
- 1 lb (450 g) raw large shrimp, peeled and deveined
- 2 bell peppers (any colors), thinly sliced
- 1 large onion, thinly sliced
- 1 cup sliced mushrooms (optional)
- 1 medium zucchini, sliced into thin strips (optional)
Fajita Seasoning
- 1 tsp chili powder
- 1 tsp paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp ground cumin
- ½ tsp dried oregano
- ½ tsp salt
- ¼ tsp black pepper
- Pinch of cayenne pepper (optional)
Citrus
- Juice of 1 lime
Optional Toppings
- Fresh cilantro, chopped
- Extra lime wedges
- Salsa
- Lettuce cups (for serving)
👩🍳 Equipment
- Large sheet pan or baking tray
- Large mixing bowl
- Sharp knife
- Cutting board
👩🍳 Step 1: Preheat the Oven
- Preheat oven to 220°C (425°F).
- Line a sheet pan with parchment paper or foil for easier cleanup.
A hot oven helps the vegetables roast instead of steam.
👩🍳 Step 2: Prepare the Vegetables
Slice the Peppers
- Remove stems and seeds.
- Slice into thin strips.
Slice the Onion
- Peel onion.
- Cut in half.
- Slice into thin half-moons.
Optional Vegetables
If using mushrooms or zucchini, slice them into similar-sized pieces for even cooking.
👩🍳 Step 3: Season the Vegetables
In a large bowl combine:
- Bell peppers
- Onion
- Mushrooms (if using)
- Zucchini (if using)
Sprinkle with all fajita seasonings.
Toss thoroughly until vegetables are evenly coated.
👩🍳 Step 4: Roast the Vegetables
Spread vegetables in a single layer on the sheet pan.
Bake
- Roast for 8–10 minutes.
This gives the vegetables a head start because shrimp cooks much faster.
👩🍳 Step 5: Prepare the Shrimp
While vegetables roast:
- Pat shrimp dry with paper towels.
- Place in the mixing bowl.
- Add half the lime juice.
- Sprinkle with a small pinch of the fajita seasoning mixture if desired.
- Toss to coat.
👩🍳 Step 6: Add Shrimp to the Pan
After vegetables have roasted for 8–10 minutes:
- Remove the sheet pan from the oven.
- Scatter shrimp evenly over the vegetables.
- Return to the oven.
👩🍳 Step 7: Finish Cooking
Bake for another 4–6 minutes.
Shrimp are done when:
- Pink and opaque
- Firm but still juicy
- Curled into a loose “C” shape
Avoid overcooking, as shrimp become rubbery quickly.
👩🍳 Step 8: Add Lime and Garnish
Remove the pan from the oven.
Immediately:
- Squeeze remaining lime juice over everything.
- Sprinkle with fresh cilantro if using.
Toss gently before serving.

💡 Tips for Perfect Shrimp Fajitas
Don’t Crowd the Pan
Spread ingredients in a single layer.
Crowding causes steaming instead of roasting.
Use Large Shrimp
Large shrimp stay juicier and are less likely to overcook.
Add More Heat
For spicy fajitas, add:
- Extra cayenne
- Jalapeño slices
- Crushed red pepper flakes
Meal Prep Friendly
Store leftovers in an airtight container in the refrigerator for up to 3 days.
