In a large bowl, combine the buttermilk, salt, black pepper, garlic powder, onion powder, and paprika.
Add the chicken strips to the marinade, ensuring they are fully coated. Cover and refrigerate for at least 1 hour, or up to overnight for best flavor.
In a shallow dish, place the flour.
Remove the chicken from the marinade, allowing excess to drip off, and dredge each piece in the flour, pressing lightly to adhere. Shake off any excess flour.
In a large skillet, heat the peanut oil over medium-high heat until it reaches 350°F.
Carefully add the chicken tenders to the hot oil in batches, making sure not to overcrowd the pan.
Fry for about 4-5 minutes per side or until golden brown and cooked through (internal temperature should reach 165°F).
Use a slotted spoon to transfer the cooked tenders to a paper towel-lined plate to drain excess oil.
Serve hot with your favorite dipping sauce.
