Ingredients for Making Easy Low Carb Turkey Tenderloin
Avocado Oil - You can use any oil you like - make sure that it is keto-friendly and high-heat safe.
Mustard - A good quality dijon goes a long way to add a tangy flavor here. I do not recommend using yellow mustard.
Fresh Herbs - Dried work in a pinch, but I think fresh is always best.
Garlic - If you don't have fresh garlic, use a teaspoon of garlic powder.
Salt - I use fine pink sea salt. In general, I recommend 1 teaspoon of salt per pound of meat. If the amount of meat you are cooking is more or less than two pounds, adjust accordingly.
Onion Powder - I don't recommend using minced fresh onion here, because given the heat and cooking time, it is likely to burn. If you want to use fresh onion, I recommend larger slices that you arrange on top of the meat to provide flavor.
Black Pepper - Fresh ground it best!
Turkey Tenderloin - I wrote the recipe for two pounds, but the marinade will work for 1 to 3 pounds.
Frequently Asked Questions
Turkey tenderloins a tender cut that is the boneless and skinless part of the turkey breast. It comes from the inside center of the turkey breast. Tenderloins typically weigh between eight ounces and one pound.
According to the USDA, turkey tenderloin should be cooked to 165° F to be safe. I like to take it out of the oven when it reaches 160° F and then let it rest. The meat will continue to increase in temperature as it rests, achieving the optimal temperature of 165° F. Always use an Instant Read Thermometer to check the temperature.
