Prepare Chicken: If not already done, pat the chicken tenders dry with paper towels. Season with salt and pepper if desired.
Heat Tallow: In a large pot or deep skillet, heat the beef tallow over medium-high heat until it reaches a temperature of about 350°F (175°C). Use a cooking thermometer to check the temperature.
Coat Chicken (Optional): If using a coating, mix powdered pork rinds with garlic powder and onion powder in a shallow dish. Dredge each chicken tender in the mixture, pressing to adhere well.
Fry Chicken Tenders: Once the tallow is hot, carefully add the chicken tenders to the pot. Do not overcrowd the pot, fry in batches if necessary. Fry each tender for 4-5 minutes on each side or until golden brown and the internal temperature reaches 165°F (74°C).
Drain: Use tongs to remove the chicken tenders from the tallow and let them drain on a wire rack or a plate lined with paper towels to remove excess fat.
Serve: Serve the chicken tenders hot. They can be enjoyed as is, or with a side of carnivore diet-compliant sauce if desired.
