Preheat your air fryer to 400°F (200°C).
Wash and slice the russet potato into thin wedges, then pat them completely dry with a paper towel.
Toss the potato wedges with half of the avocado oil and a pinch of salt, then air fry for 15-18 minutes until golden and crisp, shaking the basket halfway through.
While the potatoes cook, whisk together the almond flour, arrowroot powder, smoked paprika, garlic powder, sea salt, and black pepper in a shallow bowl.
Pat the chicken strips and peeled shrimp dry with paper towels to ensure the breading adheres properly.
Dredge each piece of chicken and shrimp in the flour mixture until evenly coated, pressing the breading into the surface.
Lightly brush or spray the breaded proteins with the remaining avocado oil.
Once the potatoes are done, remove them and keep warm; place the chicken in the air fryer basket and cook for 8-10 minutes.
Add the shrimp to the basket during the final 4 minutes of the chicken's cooking time, flipping once, until the shrimp are pink and the chicken is fully cooked.
Arrange the crispy chicken, shrimp, and fries on a platter and serve immediately.
