Begin by placing your boneless chicken tenders in a large mixing bowl. Pour in the buttermilk, followed by the garlic powder, onion powder, flaked sea salt, black pepper, and lime zest. Stir everything together until the chicken is well-coated. Cover the bowl with plastic wrap and let it marinate in the fridge for at least 30 minutes, or up to 2 hours if you have the time.
In another mixing bowl, combine the brown rice flour, shredded coconut, smoked paprika, turmeric, and a pinch of salt and pepper. This mixture will provide that delightful crunch and flavor to your chicken tenders.
Preheat your oven to 425°F (220°C). This high temperature is key to achieving that crispy exterior we all love.
Once the chicken has marinated, take each piece out and let the excess buttermilk drip off. Dip each tender into the flour mixture, ensuring an even coating. Press gently to make sure the coating sticks well.
Line a baking sheet with parchment paper. Place the coated chicken tenders on the sheet, leaving some space between each piece. Brush or drizzle each tender with extra virgin olive oil to help them crisp up in the oven. Bake for 15-20 minutes, or until the chicken is golden brown and cooked through. A meat thermometer should read 165°F (75°C) when done.
While the chicken is baking, whisk together the mayo, buffalo sauce, ketchup, and garlic powder in a small bowl. Adjust the buffalo sauce to your taste for desired heat.
Once the chicken tenders are out of the oven, let them rest for a few minutes. Serve them warm alongside your spicy dipping sauce, and enjoy the crispy, flavorful bites of goodness!
