Steps

Before you start

Pat the shrimp completely dry with paper towels before marinating—this prevents steaming and allows the Cajun crust to form properly
Use large shrimp (16–20 count) for even, quick cooking; if using smaller or larger, adjust cook time by 1–2 minutes
Set your air fryer to preheat while the shrimp marinate to save overall time
Have tongs or an oven mitt ready for the basket shake at the 4-minute mark

1
Whisk Together Marinade
- In a small bowl, whisk together the olive oil and lemon juice until combined.
- Add the minced garlic, cayenne pepper, paprika, oregano, thyme, onion powder, black pepper, and salt.
- Stir vigorously with a whisk or fork until the mixture is well blended and all spices are fully incorporated with no clumps.
- The marinade should be fragrant and slightly thick with visible specks of spices throughout.

Ready when: Marinade is smooth, well combined, and no spice clumps remain
Tip: Whisk thoroughly to dissolve all spices evenly; any clumps will result in uneven seasoning
2
Marinate the Shrimp
- Transfer the patted-dry shrimp to a medium bowl.
- Pour the marinade over them and toss and stir for 1–2 minutes, using your hands (or wear gloves) or a spoon to ensure every shrimp is evenly coated with the red and orange spice mixture.
- Cover the bowl with plastic wrap or a lid and place it in the refrigerator.
- Marinate for at least 15 minutes; for deeper, more intense Cajun flavor, you can marinate for up to 1 hour.

Ready when: All shrimp are evenly coated with the spice mixture; bowl is covered
Tip: Don't skip the drying step from before marinade; moisture prevents the blackened crust from forming and causes steaming
3
Preheat the Air FryerOven 400°F / 205°C
- Set your air fryer to 400°F (204°C).
- Press the preheat button and let the air fryer run for 3 minutes.
- You can start this step while the shrimp marinate, which saves overall cooking time.
- The indicator light will usually turn off or change when the unit has reached temperature.

Ready when: Air fryer preheat indicator signals ready or 3 minutes have elapsed
Tip: Preheating is essential for quick, even cooking; skipping this results in slower, less effective crust development
4
Arrange Shrimp in Air Fryer
- Remove the marinated shrimp from the refrigerator.
- Carefully arrange them in a single, flat layer in the air fryer basket, making sure each shrimp lays mostly flat or in a gentle curve.
- Leave a small amount of space between each piece—they should not touch or overlap.
- If you have more than will comfortably fit in one layer (typically 20–24 large shrimp max), cook in two batches rather than stacking, which blocks air circulation.

Ready when: Shrimp are arranged in a single, uncrowded layer with visible space between each one
Tip: Overcrowding the basket prevents proper air circulation and stops the Cajun spices from caramelizing; you'll get steamed shrimp instead of blackened shrimp

Cook Shrimp with Midway ShakeOven 400°F / 205°C
- Carefully insert the air fryer basket into the preheated unit.
- Set the timer for 8 minutes.
- Let the shrimp cook undisturbed for the first 4 minutes.
- At the 4-minute mark, pause the air fryer (press pause or stop), carefully pull out the basket using tongs or an oven mitt, and gently shake or toss the basket side to side for about 30 seconds to redistribute the shrimp for even cooking.
- Reinsert the basket and resume cooking for the remaining 4 minutes.
- You should see the marinade spices caramelize and darken, and the shrimp will turn from translucent gray to opaque pink with dark, charred spots forming.

Ready when: All shrimp are opaque and pink throughout; exterior shows dark caramelized or charred spots; internal temperature reaches 145°F (63°C)
Tip: The dark, charred spots are caramelization from the spices—not burnt flavor. They are the signature of authentic blackened dishes and taste delicious; embrace them
6
Rest and Serve
- When the timer sounds, carefully remove the air fryer basket using tongs or an oven mitt.
- Using tongs or a fork, transfer the shrimp to a serving plate or individual plates.
- Let rest for 1–2 minutes to cool slightly.
- Serve immediately while still warm.
- Optionally, garnish with fresh lemon wedges, hot sauce, or a drizzle of fresh lemon juice for brightness.

Ready when: Shrimp are warm and ready to eat; no steam rising excessively
Tip: Serve immediately for the best tender texture; as shrimp cool further, they firm up and lose juiciness

Tips

Pat the shrimp completely dry before marinating. Any excess moisture prevents the Cajun crust from forming and can cause steaming instead of the desired blackened sear.
Do not overcrowd the air fryer basket. Shrimp need space for hot air to circulate freely; if cooking 2+ pounds, work in batches rather than layering.
The dark, charred spots are caramelization from the spices—not burnt flavor. They are the signature of classic blackened dishes and taste smoky and delicious; embrace them as a sign of success.
Serve immediately with lemon wedges, hot sauce, or a quick remoulade sauce for dipping. The intensely seasoned Cajun crust pairs beautifully with cool, creamy, or tangy accompaniments.

Make ahead

Prepare the Cajun spice marinade up to 2 days in advance and store in an airtight container in the refrigerator. Marinate the shrimp up to 8 hours ahead; longer marinating (up to 12 hours) intensifies the Cajun flavors, but avoid marinating longer than 12 hours or the lemon juice will start to denature the shrimp protein. Air fry just before serving for the best texture and crispness.

Storage & reheating

Room temperature: Serve immediately for best taste and texture. Leftover cooked shrimp can sit at room temperature for up to 1 hour before quality begins to decline. Refrigerator: Store leftover cooked shrimp in an airtight container for up to 2 days. Reheat gently in the air fryer at 350°F for 2–3 minutes or in a skillet over medium heat for 2–3 minutes until warmed through, stirring occasionally. Freezer: Freeze cooked shrimp in an airtight container or freezer bag for up to 1 month. Thaw in the refrigerator overnight before reheating. Marinated uncooked shrimp can also be frozen for up to 2 months; thaw overnight in the refrigerator and air fry directly from thawed.

Substitutions

paprika → Smoked paprika (1 tbsp / 6 g) for deeper smokiness, or chili powder (1 tbsp / 6 g) for more heat and earthiness; if using chili powder, reduce the cayenne to ½ tsp (1 g). Smoked paprika intensifies the Creole smokiness; chili powder adds a different heat profile
fresh lemon juice → Lime juice (2 tbsp / 30 ml) for a brighter, slightly tropical citrus note; or white wine vinegar (2 tbsp / 30 ml) for tanginess without citrus. Lime juice works beautifully with Cajun spices; vinegar adds brightness and a different acid
cayenne pepper → Hot sauce (½–1 tsp / 2.5–5 ml) mixed into the oil for a different heat style and extra flavor; or reduce cayenne to ½ tsp (1 g) for milder heat; or use white pepper (½ tsp / 1 g) for heat without the red color. Hot sauce adds depth; reducing cayenne makes the dish less spicy; white pepper provides subtle heat
fresh garlic cloves → Garlic powder (1 tsp / 3 g) for convenience, or jarred minced garlic (1 tbsp / 15 g). Fresh garlic provides superior flavor and presence, but powder and jarred options work in a pinch
