Keto steak marinade FAQs:
Any type or cut of steak is great for keto. Beef steaks are a naturally low carb meat that is perfect for a keto diet.
Marinades are best for tougher cuts of meat, so they are especially good for cheaper steak cuts like flank steak, skirt stake, and hanger steaks but you can marinade all cuts of steak. You'll see the biggest difference in texture and flavour working with smaller steaks or steaks that have been cut into bite-sized pieces.
There is a total of 5 grams of carbs per serving of this marinade with 1 gram of fiber and 1 gram of sugar. However, that carb count assumes that you consume ALL the marinade when you eat the steak which in reality doesn't happen. Much of the marinade will get cooked off, and some gets discarded when you transfer the steaks to the grill so in reality the carb count would actually be much lower.
Yes, balsamic vinegar is great for marinades because not only does the acid in it help tenderize the meat, but it adds a delicious, sweet flavour while still being sugar free.
