Instead of relying on a cast iron skillet or sheet pan, try making shrimp fajitas on the grill!
This shrimp fajitas recipe (also known as fajitas de cameron) is a great recipe because it keeps the heat – and the mess – out of the kitchen.
Plus with this easy dinner everyone in the family can dish up whatever part of the shrimp fajita they like.
This recipe uses a really simple fajita seasoning that’s flavorful but not overpowering. And these fajitas are gluten free, dairy free, paleo, and can be Whole30 compatible.
So put down that cast iron pan and let’s get grilling!
Ingredients
- 1 lb large shrimp, peeled & deveined (raw jumbo shrimp or medium shrimp would also work, though they may have a slightly different cooking time)
- A large onion (I like a sweet onion)
- 2 bell peppers (I used red and yellow bell peppers but any color will do)
- Smoked paprika
- Garlic powder
- Ground cumin
- Kosher salt (I use Diamond Crystal, which is slightly less salty than other brands of kosher salt)
- Ground black pepper
- Oil (I use avocado or olive oil. If you’re on a Whole30 just make sure it’s compatible)
I’ve written condensed directions here including pictures so you can see how to make this recipe. The full set of detailed instructions are in the recipe card at the bottom of the page.

How to make grilled shrimp fajitas
- Prep the onions by slicing them into roughly 1 inch thick slices. Stick a toothpick in them to prevent them from falling apart, then oil them up.
- Prep the bell peppers by removing the tops and seeds, then slicing them into halves. Put the halves in a medium bowl with oil and salt and set aside.
- Prep the shrimp by drying them off with a paper towel, then combining the seasoning in a small bowl and pouring it over the shrimp. Pour some oil over the shrimp as well and mix it all together with your hands.
- Put the seasoned shrimp on skewers, placing them carefully so they don’t fall off during grilling. You should be able to get 5 or so on a skewer.
- Preheat your gas grill to 400 degrees F (a medium-high heat) then place the onions in a single layer on the hot grill over direct heat. Close the lid and cook for 4 minutes.
- Once the 4 minutes are up, flip the onions over then place bell peppers on the grill and cook for 3 minutes with the lid closed. Then turn the bell peppers over and cook for another 3 to 5 minutes until both are lightly charred.
- Remove the veggies from grill and set aside to cool. Turn the heat down a bit to 350 degrees F. Add the shrimp skewers to the grill and close the lid, cooking for 2 minutes. Open the lid, flip the skewers to the other side and grill shrimp another 2 to 4 minutes until they are cooked through.
- Remove the shrimp from the grill and place on a platter. Cut the onion slices in half and cut the bell peppers into quarter-inch slices and assemble on the platter with the shrimp. Serve in a warm tortilla or on top of some rice piled with toppings and enjoy!
Fajita Toppings & Serving Ideas
- guacamole or plain avocado slices
- chopped cilantro
- sour cream (omit if dairy free, paleo, or Whole30)
- a squeeze of lime juice
- pico de gallo
- jalapeno
- tortillas (corn or almond/cassava if paleo)
- Mexican rice
FAQ
You might have some questions about these grilled shrimp fajitas skewers – let’s get to those now.
How do you know the shrimp is cooked?
You’ll know the shrimp is cooked because they will be pinker in color and completely opaque (not see through at all). You can also take the internal temperature of the shrimp – they should be at 145 degrees F.
Do you use cooked or raw shrimp?
This recipe calls for raw shrimp. You could use already cooked shrimp and not grill them, but you’ll lose the flavor of the dish.
What kind of tortillas did you use?
The tortillas I used were Siete Almond Flour tortillas. I’ve also tried their Cassava Flour tortillas and those work well too. You could also use corn tortillas or just leaves of lettuce (if on a Whole30).
RECIPE TIPS & SUBSTITUTIONS
- You can use frozen shrimp. You’ll just have to defrost them before grilling. You can either stick the frozen shrimp in the fridge to defrost a day ahead of time, or if you’re forgetful like me then take them out of the bag, put them in a colander, and let them run under cold water for 5-10 minutes until they’re defrosted.
- Metal skewers are best, but wooden will work. Every time I’ve tried grilling with wooden skewers they get charred and burned up – even when they’ve been soaked all day. I finally bought a set of metal skewers and I recommend you do too. You can find them at local stores (during grilling season) or these ones on Amazon are similar to the ones I have (affiliate link).
- Use toothpicks in your onions if you’re worried about them falling apart. Carefully push the toothpick into one side of the onion until it reaches the middle. This will help keep it together when it’s on the grill.
- Switch up the seasoning a little. If you don’t have smoked paprika, you can use regular. You can also add up to ¼ tsp of either cayenne pepper or ground chipotle powder to give the shrimp a spicier kick.
- Use a meat thermometer if you’re worried about undercooking the shrimp. You can measure the internal temperature with it and be reassured. We’ve had a Thermapen for years and love it (affiliate link).

Equipment
- A large dish or platter
- Toothpicks
- A large bowl or casserole dish
- 4 to 5 12-inch metal skewers
- A grill
Ingredients
For the Shrimp
- 1 lb raw shrimp peeled & deveined
- ¾ tsp kosher salt
- ½ tsp smoked paprika
- ¼ tsp garlic powder
- ¼ tsp ground cumin
- ⅛ tsp ground black pepper
- 2 tsp oil
For the Fajitas
- 1 large onion
- 2 bell peppers
- 1 tbsp oil avocado or olive
- ½ tsp kosher salt
For Serving
- Paleo tortillas or lettuce leaves for Whole30
- Avocado
- Chopped cilantro
- Lime wedges
Instructions
- Remove the ends of the onion using a large sharp knife and cutting board. Peel off the thin outer layers (the darker colored ones). Using a large sharp knife and cutting board, slice the onion into ½ inch rings. For a large onion this will result in about 4-5 rings per onion. Place the rings in a single layer in a dish or large platter.
- Measure out ½ tbsp of oil and gently pour a little of the oil on top of each onion slice, portioning it out as equally as you can. Rub the oil into both sides of the onion, making sure the surface is fully covered. If your onions are coming apart, grab some toothpicks and insert them into the side of the onion, so that they go through each layer to the middle of the onion and help hold it together. Set aside.
- Remove the tops of the peppers using the knife and cutting board. Make an incision less than half an inch down from the top of the pepper and carefully cut all the way around until the top of the pepper comes off (kind of like a hat). Slice both bell peppers in half from top to bottom, removing any seeds with your fingers and discard them.
- Place both the bell peppers in a medium bowl then drizzle with ½ tsbp oil and sprinkle ½ tsp Diamond Crystal kosher salt. Use your hand to spread the oil and salt onto the veggies until they’re well covered. Set aside.
- Next make the seasoning blend. Use measuring spoons to measure out ¾ tsp of Diamond Crystal kosher salt, the smoked paprika, garlic powder, ground cumin, and ground black pepper, then combine them in a small bowl. Set aside.
- Get out a large bowl (or I like to use a glass casserole dish) and place the raw shrimp in it. Dry the shrimp off using paper towels (this helps the seasoning stick better), then throw the towels away. Before you season the shrimp, measure out 2 teaspoons of oil and place it in a small bowl – this way you won’t have to touch the oil bottle with dirty hands.
- Sprinkle the seasoning over the shrimp and stir everything together with your hand. Then drizzle the oil over the shrimp as well. Use your hands again to combine everything together, making sure each shrimp is as evenly coated as possible.
- Take out one metal skewer and gently push a shrimp onto it, making sure to get the skewer’s point as close to the middle of the shrimp as possible. Slide it down to the bottom of the skewer, then keep repeating until all of the shrimp are on all of the skewers. Be sure not to space the shrimp too close together so they cook more evenly.
- Place the same size of shrimp together on the same skewer – smaller ones on one skewer, larger ones on another. You should be able to fit 5 shrimp onto 1 skewer, depending on the size of your shrimp (or if you’re using different sized skewers). Once all the shrimp are on skewers, set aside while you prep the vegetables.
- Heat the grill to 400 degrees F, then once it comes to temperature place the onion slices on the grill with a pair of tongs (whichever side down you like). Cook for 4 minutes with the lid closed.
- After the 4 minutes are up, flip the onions using the tongs then place the bell peppers on the grill. Cook for another 3 minutes with the lid closed. Then flip the bell peppers over and cook for an additional 3 to 5 minutes, until both are lightly charred. They should be soft but not completely limp. Remove from the grill and set aside to cook.
- Next place the shrimp skewers on the grill. Close the lid and cook for 2 more minutes. Open up the lid and flip both the shrimp (be sure to wear an oven mitt as the skewers will be hot!), cooking another 2 to 4 minutes. Remove them from the grill once they are opaque all the way through and at an internal temperature of 145 degrees F.
- Remove the shrimp from the grill and place on a large platter. Cut the onion in half with the knife and cutting board and break apart the rings to make slices of onion. Cut the bell pepper halves into quarter-inch slices and place both on the platter with the shrimp. Eat with gluten free or paleo tortillas, avocado, chopped cilantro, or other toppings.
