Preheat your oven to 425°F.
In a shallow dish, lightly whisk the egg.
In another dish, combine the almond flour, garlic powder, onion powder, salt, and pepper.
Dip each chicken tender first into the egg, then coat thoroughly with the almond flour mixture.
Place the coated chicken tenders on a baking sheet lined with parchment paper.
Arrange the asparagus spears on a separate baking sheet, drizzle them with olive oil, and season with salt and pepper.
Bake the chicken tenders for 20-25 minutes, turning halfway through, until they are crispy and cooked through.
Simultaneously, roast the asparagus for 15 minutes until tender but still crisp.
Serve the crispy chicken tenders hot alongside the roasted asparagus.
