In a large bowl, combine the buttermilk, salt, black pepper, garlic powder, onion powder, and paprika.
Add the chicken strips to the buttermilk mixture, ensuring they are well coated. Cover and refrigerate for at least 1 hour, or overnight for best flavor.
In a shallow dish, place the flour.
Remove the chicken from the buttermilk mixture, allowing excess to drip off, and dredge each piece in the flour until fully coated.
In a large skillet, heat the peanut oil over medium-high heat until it reaches 350°F.
Carefully add the chicken tenders in batches, making sure not to overcrowd the pan. Fry for about 4-5 minutes on each side or until golden brown and cooked through.
Use a meat thermometer to ensure the internal temperature reaches 165°F.
Once cooked, transfer the chicken tenders to a paper towel-lined plate to drain excess oil.
Serve warm with your favorite dipping sauces.
