How to Make It: Step-by-Step Instructions
Step 1: Thaw and Dry the Shrimp Thoroughly
If you are using frozen shrimp, place them in a colander and run cold water over them for about 5 minutes until completely thawed. Dump the wet shrimp onto a large baking sheet lined with three layers of heavy paper towels. Place more paper towels on top and press down firmly to blot away every single drop of surface moisture. Pro Tip: This drying phase is the absolute secret to success! Wet shrimp will steam in the air fryer instead of searing, turning your fajitas into a soggy, watery mess.
Step 2: Slice Your Veggies Uniformly
Grab your red bell pepper, green bell pepper, and half of a large white onion. Using a sharp chef’s knife, slice them into thin, uniform strips about ¼-inch wide. Try to keep the vegetable slices all the same thickness so they cook through at the exact same rate. Place the sliced peppers and onions into a large, clean mixing bowl alongside your completely dry, peeled shrimp.
Step 3: Season and Coat Everything Evenly
Pour 3 tablespoons of melted butter (or high-heat avocado oil) directly over the shrimp and vegetable mixture. Sprinkle your entire packet of taco seasoning, a pinch of garlic powder, and a dash of sea salt across the top. Use a pair of kitchen tongs or your hands to toss the ingredients together vigorously for about 45 seconds until every single piece of shrimp and every strip of pepper is thoroughly coated in oil and spices.
Step 4: Arrange the Air Fryer Basket
Preheat your air fryer to 400°F (204°C) for 3 minutes. Pull out the hot basket and lightly spray the bottom grid with a mist of avocado oil. Dump your seasoned shrimp, peppers, and onions straight into the basket. Shake the basket gently to spread the ingredients out into an even layer. Do not pack the basket completely solid; if your air fryer is small, cook this in two separate batches so the hot air can circulate freely around the food.
Step 5: Air Fry to Blistered Perfection
Slide the basket into the machine and cook at 400°F (204°C) for 8 to 12 minutes. At the 5-minute mark, pull the basket out and give it a heavy shake to flip the ingredients around. You are looking for the shrimp to curve into a gentle “C” shape and turn opaque pink, while the edges of your bell peppers and onions should show gorgeous, dark, caramelized char marks.
Step 6: Dress and Serve Hot
Carefully dump the sizzling hot fajita mixture out of the basket onto a large serving platter. Immediately squeeze the juice of half a fresh lime across the top to release the aromatics. Top your plate with a massive, generous dollop of cool avocado salsa and serve immediately alongside warm low-carb tortillas or over a bed of seasoned salad greens.
Pro Tips for the Best Recipe
Watch the Shrimp Shape: Keep a close eye on your cooking timer! Perfectly cooked shrimp will curve into a loose “C” shape and remain tender and juicy. If your shrimp curl up tightly into a dense, hard “O” shape, they are overcooked and will possess a tough, rubbery texture.
The Avocado Salsa Finish: Never add your avocado salsa or guacamole into the hot air fryer basket during the cooking process! Always use it as a fresh, ice-cold topping right before serving to create a luxurious temperature contrast against the hot, spicy meat.
Do Not Crowd the Basket: If you have a small, compact air fryer, do not attempt to cram the entire recipe into the basket at once. Overcrowding stops the rapid air movement, causing the vegetables to release water and stew instead of crisping. Cook in two quick, small batches for the best char.
Use High-Smoke Point Fats: If you choose not to use melted butter, opt for avocado oil over standard extra virgin olive oil. Avocado oil safely handles intense 400-degree heat without smoking, burning, or breaking down into bitter compounds during the cook cycle.
Storage
- To Store: Place your leftover shrimp, peppers, and onions inside an airtight glass meal prep container. Keep it stored in your refrigerator for up to 2 days. Because seafood goes bad faster than beef or chicken, it is best enjoyed quickly!
- To Freeze: We do not recommend freezing this finished dish, as cooked bell peppers turn completely mushy, watery, and lose their structure entirely once thawed out from a frozen state.
- To Reheat: Avoid using a microwave at all costs, as it will instantly turn your tender shrimp into tiny, rubbery superballs. Instead, revive your leftovers by tossing them back into the Air Fryer at 350°F (177°C) for 2 to 3 minutes until just warmed through and crisp.
Frequently Asked Questions
Can I make this exact recipe using chicken or steak instead?
Absolutely! You can easily swap the protein out for thin strips of chicken breast or flank steak. Just keep in mind that chicken and beef require more time to cook through safely than seafood. You will need to air fry chicken or steak strips for an extra 6 to 8 minutes at 400°F.
What should I do if my frozen shrimp still have the tails attached?
Simply pinch the base of the tail firmly between your thumb and index finger and pull gently before seasoning. Removing the tails before cooking makes this a seamless, mess-free finger food that you can eat instantly without stopping to peel hot shells at the dinner table.
Why did a puddle of water form at the bottom of my air fryer basket?
This occurs if the shrimp were not dried thoroughly with paper towels before tossing in oil, or if you used frozen peppers that released excess moisture. Ensure everything is bone-dry before the seasoning phase to achieve a clean, oil-seared finish.
Is this recipe suitable for a strict keto diet?
Yes, it is perfectly suited for keto! Just double-check the back of your store-bought taco seasoning packet to ensure it doesn’t contain hidden fillers like cornstarch or added cane sugars, which can easily spike your daily carbohydrate count.

10-Minute Air Fryer Shrimp Fajitas (Crispy Low Carb Recipe)
Ingredients
1 lb frozen shrimp (peeled, deveined, tails removed)
1 large red bell pepper (sliced into thin strips)
1 large green bell pepper (sliced into thin strips)
½ large white onion (sliced into thin strips)
1 packet low-sodium taco seasoning
3 tbsp butter (melted, or high-quality avocado oil)
½ cup fresh avocado salsa (for serving)
1 large fresh lime (cut into wedges)
½ tsp garlic powder
A pinch fine sea salt
Instructions
Thaw your shrimp under cold water. Lay them out flat onto several sheets of heavy paper towels. Press another towel firmly over the top until they are completely dry on the surface.
Slice your red bell pepper, green bell pepper, and white onion into thin, uniform strips roughly ¼-inch thick so they all soften at the exact same speed inside the machine.
Place the dry shrimp and sliced vegetables into a large mixing bowl. Pour your melted butter or avocado oil over the top, then dump the taco seasoning packet, garlic powder, and salt across the ingredients. Toss heavily until coated.
Preheat your air fryer to 400°F (204°C). Arrange your seasoned shrimp and vegetable mixture into the basket in a single, even layer. Do not pile them too high, or they will steam instead of searing.
Cook at 400°F (204°C) for 8 to 12 minutes. Make sure to pull the basket out at the 5-minute mark to give it a heavy shake. Stop cooking once the shrimp are pink and opaque, and the pepper edges display a beautiful grill char.
Transfer the hot fajitas to a platter. Squeeze a fresh lime wedge over the top to activate the flavors. Top with cold avocado salsa and serve immediately with your favorite low-carb wraps.
Notes
Blot the Shrimp Bone-Dry: Do not rush the drying step! Any leftover water clinging to the shrimp will create steam inside the hot basket, ruining your chances of getting those gorgeous, crispy, charred restaurant-style edges. The Loose ‘C’ Shape Trick: Watch your shrimp carefully near the end of the timer. If they curl up into tight, firm little circles, they are overcooked. Pull them out when they form a loose ‘C’ shape to keep them tender. Shake the Basket Mid-Way: Always shake the basket thoroughly halfway through the cooking process. This redistributes the vegetables and ensures that every side gets direct exposure to the high-velocity hot air for an even sear. Meat Substitutions: To make this with chicken or steak, slice the meat into identical thin strips and increase the total cooking time to 15 to 18 minutes at 400°F to ensure the thicker proteins cook through safely. Reheat Only in Air Fryers: Never use a microwave for leftover fajitas, as it turns seafood completely rubbery. Pop leftovers back into the air fryer basket at 350°F for 2 minutes to restore the perfect texture.
