How to Make Char Siu beef Tenderloin

Step 1: Marinate the Beef

Place your 2 beef tenderloins in a large sealable freezer bag or shallow dish.
In a medium bowl, mix together:
¼ cup soy sauce
2 Tablespoons creamy peanut butter
1 Tablespoon molasses
1 Tablespoon light brown sugar
3 teaspoons red food coloring
2 teaspoons apple cider vinegar
2 teaspoons sesame oil
1 teaspoon Chinese five spice powder
1 teaspoon garlic powder
1 teaspoon olive oil.
Pour the marinade over the beef, squeeze any air out of the bag, and seal it tightly. Ensure the beef is well covered and refrigerate for at least 2–3 hours (up to overnight). Optimal marination is between 6–8 hours but do not exceed 24 hours.

Remove the beef from the marinade bag and place it on a sheet pan or baking dish. Discard any remaining marinade.
Bake at 400°F, tented with aluminum foil for about 10 minutes. Uncover and continue baking for an additional 15–25 minutes until the internal temperature reaches 145°F.

Step 3: Serve and Enjoy!

Remove the beef from the oven and let it rest for about 5–10 minutes before slicing thinly.
Garnish with sliced scallions, minced fresh cilantro, toasted sesame seeds, julienned or pickled carrots, and/or sriracha hot sauce as desired.

Marinate adequately: Ensure you marinate for at least 2-3 hours, but aim for 6-8 hours for optimal flavor absorption.

Use a meat thermometer: To check for doneness, aim for an internal temperature of 145°F; this guarantees juicy meat without being overcooked.
Let it rest: Allowing the beef to rest for 5-10 minutes after baking helps retain juices for more flavorful slices.
Slice against the grain: Cutting against the grain ensures each bite is tender and easy to chew.

Common Mistakes to Avoid

When making Char Siu beef Tenderloin, here are some common mistakes to watch for.

Not marinating long enough: Skipping the extended marination time can lead to less flavorful beef. Aim for at least 6 hours for optimal results.
Skipping the resting period: Cutting into the beef immediately after cooking can cause juices to escape. Always let it rest for 5-10 minutes before slicing.
Using regular soy sauce: If you’re looking for a gluten-free option, be sure to use gluten-free soy sauce or tamari to keep the dish accessible.
Ignoring temperature checks: Cooking without checking the internal temperature may result in undercooked or overcooked meat. Use a meat thermometer for accuracy.
Overcrowding the baking pan: Placing too many pieces of beef in one pan can lead to uneven cooking. Ensure ample space between each tenderloin on the baking sheet.
