Tips from an expert home chef

  • The cilantro lime marinade will be kind of thick. That’s ok! You want it to coat and stick to the shrimp and fajita veggies as much as possible.
  • Use whatever tortilla shells you want. Use lettuce wraps or keto tortillas for low-carb or you can use corn or larger fajita tortillas if desired.
  • Make it a fajita bowl. You could even skip the shells entirely and serve it in a bowl with cauliflower or regular rice and/or some other greens or veggies.
  • Clean, peel and remove the tail from the shrimp before cooking. This will save you the hassle of taking the tails off the hot cooked shrimp :).
  • Don’t forget the toppings! We love a good dollop of our homemade chipotle aioli sauce. Or some chopped fresh cilantro and avocado are great options too.

Easy (30-Minute!) Keto Fajitas with Shrimp

Following the Keto diet? These low-carb shrimp fajitas are a fast and easy keto-friendly dinner option. The cilantro-lime shrimp marinade is the secret sauce — literally! To serve, spoon the fajita mixture into lettuce leaves (or tortillas), and top with your favorite toppings and enjoy!


For the cilantro-lime sauce:

  • 2 limes, juice of
  • 1/4 cup avocado oil
  • 1/4 cup cilantro, chopped
  • 1 tbsp cumin
  • 1 tbsp garlic powder
  • 1 tbsp chili powder
  • 2 tsp ground pepper
  • 1 tsp sea salt

For the Fajitas:

  • 1.5 lbs jumbo shrimp, peeled and deveined
  • 3 bell peppers, sliced into strips
  • 1 onion, sliced into strips

For serving:

  • 1 avocado, sliced
  • Chipotle aioli
  • Salsa
  • Chopped cilantro
  • 2 bunches broad leaf greens (bibb, romaine, chard, etc.) , (or use corn or Siete tortillas – but greens only for Whole30)



  • Preheat oven to 400° Fahrenheit and line a large sheet pan with parchment paper.
  • Prepare the lime sauce by mixing all of the sauce ingredients together in a large bowl. You'll add the shrimp, bell peppers and onion to this bowl, so use a large enough bowl for that. Alternatively, you can mix the sauce up in a small bowl and just toss with the other ingredients on the sheet pan.
  • Slice bell peppers and onion as noted and add them to the bowl.
  • Add the shrimp to the bowl and toss/mix to coat everything with the lime sauce.
  • Spread the shrimp and veggies out on the sheet pan. Place in the oven to bake for 10-15 minutes. Watch carefully after 10 minutes and remove when the shrimp and veggies are cooked to your liking. If you want a little char on the top, you can switch the oven to broil for the last few minutes.
  • While the fajitas are cooking, prepare lettuce leaves for shells and toppings as desired.
  • To serve, spoon fajita mixture into lettuce leaves (or tortillas), top with your favorite toppings and enjoy.
