TABLE OF CONTENTS
Keto Sheet pan Shrimp Fajitas Ingredients
- Shrimp – When preparing shrimp fajitas, I thaw my frozen shrimp. It’s essential to make sure the shrimp is peeled and deveined, and that the tails have been removed. I typically opt for large or extra-large(jumbo) shrimp for a heartier bite.

Thawing Frozen raw shrimp:
- Overnight: Place the frozen shrimp in a bowl or sealed bag in the fridge for up to 24 hours. To prevent drips, you can put the bag on a rimmed baking sheet or in a bowl.
- In cold water: Put the frozen shrimp in a sealed bag and submerge it in cold water for 10–45 minutes, depending on the shrimp’s size. You can place a plate or lid over the bag to keep the shrimp submerged. After thawing, you can pat the shrimp dry with a paper towel
SPICES
- Chili Powder– Chili powder is aromatic and savory, and is made from ground chile peppers.
- Paprika – I used smoked paprika. Smoked paprika has a round, smoky, woodsy, spicy flavor, but regular paprika can be used.
- Garlic powder– Fresh minced garlic clove can be used instead of powder.
- Onion powder
- Cumin – Ground cumin enhances the flavor of the shrimp and veggies.
- Salt & Pepper
COOKING OIL
- Olive oil, or avocado oil
VEGGIES
- Bell Peppers – I used 3 different colors of bell peppers
- Onions – White onion sliced
- Lime

Tortillas
- Keto-certified tortillas like Mission Zero Net Carbs, or Guerrero Zero Net Carbs
Optional TOPPINGS
Guacamole, pickled jalapeños, sour cream, spicy pickled red onions, or chopped cilantro
How to Make Sheet Pan Shrimp Fajitas

- Add the shrimp and vegetables to a sheet pan and drizzle liberally with olive oil.
- Mix the spices and sprinkle evenly over the shrimp and vegetables, then toss to coat.

- Bake for 8 minutes.
- After baking the dish for 8 minutes, you should then switch on the broiler and continue cooking for an additional 2 minutes. This will help to achieve a slightly charred effect on the peppers and shrimp.
Get ready to experience an explosion of flavors when you serve your sizzling shrimp fajitas! Squeeze those zesty fresh lime wedges right on top and heat those tortillas for a mouthwatering meal that’s quick, fast, and oh-so-delicious!

Shrimp Fajita rice bowl option
- Rice Bowl: Get ready to indulge in a flavorful meal! Serve up some mouthwatering shrimp fajitas in a rice bowl, with keto cilantro lime rice made from cauliflower. Don’t forget to top it off with your favorite fixings such as creamy avocado slices, tangy pickled jalapeños, or a generous dollop of guacamole. Enjoy!

Storing And Reheating Tips
If you have leftover shrimp fajitas, the great thing is that you can easily reheat them and customize the toppings for a fresh and exciting flavor. Here are some tips on how to store them:
