Ingredients & Substitutions

These are the main ingredients and substitutions for Whole30 pork tenderloin. Scroll down to the recipe card for full ingredients list and instructions.

Use pork tenderloin, not pork loin. They are different!

The sea salt and pepper add the perfect amount of flavor without being overwhelming.

Any cooking fat will work. Butter, ghee, avocado oil and refined coconut oil can be used instead of olive oil.

Coconut aminos is the gluten free and soy free version of soy sauce. It can be found in the Asian aisle at most grocery stores. I buy the brand Big Tree Farms on Amazon.

Minced garlic and ground ginger add a ton of flavor to the sauce and the pork. Feel free to use garlic powder or fresh ginger if needed.

The chopped green onion garnish is entirely optional!

Expert Tips & Tricks

For best results, use a fresh high quality pork tenderloin.

If you only have frozen, thaw completely.

If pork is too long, slice in half so that it fits in the pan.

Pat pork dry with paper towels. This helps the pork get even more crispy when seared.

Allow oil to get hot before placing pork into skillet. This also allows the pork to get crispy on the outside.

After done cooking, let pork sit in juices in the skillet for 5 minutes. This keeps the pork moist and tender.

Use a meat thermometer to accurately measure internal temperature of meat. Cook until at least 145 degrees Fahrenheit. This is considered safe to eat.
