👩‍🍳 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

1. Remove stems and seeds.
2. Slice into thin strips.

Slice the Onion

1. Peel onion.
2. Cut in half.
3. 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:

1. Pat shrimp dry with paper towels.
2. Place in the mixing bowl.
3. Add half the lime juice.
4. Sprinkle with a small pinch of the fajita seasoning mixture if desired.
5. Toss to coat.

---

👩‍🍳 Step 6: Add Shrimp to the Pan

After vegetables have roasted for 8–10 minutes:

1. Remove the sheet pan from the oven.
2. Scatter shrimp evenly over the vegetables.
3. 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:

1. Squeeze remaining lime juice over everything.
2. 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.
