Ingredients You’ll Need

For the Pork Tenderloin

  • 1–2 pounds of pork tenderloin
  • Salt and pepper (for seasoning)

For the Homemade Teriyaki Sauce (Marinade & Glaze)

  • ½ cup soy sauce (low sodium recommended)
  • ⅓ cup brown sugar or honey
  • 2 tablespoons rice vinegar or mirin
  • 2 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated (or ½ teaspoon ground)
  • 1 teaspoon sesame oil (optional)
  • 1 tablespoon cornstarch + 2 tablespoons water (for thickening the glaze)

Optional Garnishes

  • Toasted sesame seeds
  • Sliced green onions
  • Pineapple slices or mango chunks (for a tropical twist)

Note: You can substitute pork tenderloin with pork loin, but tenderloin is more tender and faster-cooking.

Prepping the Pork Tenderloin

Before you start marinating, properly preparing the pork ensures even cooking and better flavor absorption.

Trimming the Tenderloin

  • Remove the silver skin: This is a thin, tough membrane that doesn’t break down during cooking.
  • Trim any large fat deposits.

Portioning (Optional)

  • You can leave the tenderloin whole or slice it into medallions for quicker cooking and better surface area for sauce.

Season Lightly

  • Even though the marinade has soy sauce (which is salty), lightly season the pork with salt and pepper to enhance its base flavor.

Marinating the Pork

Marination is essential for flavor penetration and tender texture. It allows the teriyaki blend to seep into the meat and infuse it with rich umami notes.

Making the Marinade

  1. Combine soy sauce, brown sugar (or honey), rice vinegar, garlic, ginger, and sesame oil in a bowl.
  2. Whisk until the sugar is fully dissolved.

Marinating Process

  • Place the pork into a large zip-top bag or shallow glass dish.
  • Pour the marinade over the pork and seal/cover.
  • Refrigerate for at least 30 minutes, but for best results, marinate for 4–6 hours or even overnight.

Tip: Turn the meat occasionally to ensure even marination.

Safety Note:

  • Always marinate in the refrigerator, not at room temperature.
  • Discard the used marinade or boil it before using as a sauce.

Cooking Methods

There are multiple ways to cook teriyaki pork tenderloin, depending on your kitchen tools and preference. Below are the four best methods.

Oven-Baked Teriyaki Pork Tenderloin

This is one of the most foolproof methods and yields juicy, evenly cooked pork with minimal effort.

Instructions:

  1. Preheat oven to 400°F (204°C).
  2. Remove pork from marinade and place it on a baking dish or roasting pan.
  3. Optional: Sear the pork in a skillet for 2–3 minutes per side before baking to develop a caramelized crust.
  4. Bake for 20–25 minutes, depending on the thickness.
  5. Use a meat thermometer to check doneness—145°F is perfect for juicy pork.
  6. Rest for 5–10 minutes before slicing.

Making the Glaze:

  1. Pour leftover marinade into a saucepan.
  2. Bring to a boil, then reduce heat to simmer.
  3. Stir in cornstarch slurry to thicken (1 tbsp cornstarch + 2 tbsp cold water).
  4. Simmer until thickened, 3–5 minutes.
  5. Brush or drizzle over cooked pork.

Grilled Teriyaki Pork Tenderloin

Grilling adds smoky depth to the already rich teriyaki flavor and is perfect for summer meals.

Instructions:

  1. Preheat grill to medium-high heat (around 400°F).
  2. Lightly oil the grates.
  3. Grill tenderloin directly over heat for 3–4 minutes per side to sear.
  4. Move to indirect heat and cook with the lid closed for another 15–20 minutes.
  5. Baste occasionally with boiled or reserved marinade.
  6. Use a meat thermometer to ensure it reaches 145°F internally.
  7. Let rest before slicing.

Optional: Serve grilled pork with grilled pineapple rings for an island-style twist.

Pan-Seared + Oven-Finished Method

This method gives you the sear of the stovetop and the even doneness of the oven.

Instructions:

  1. Preheat oven to 375°F.
  2. Heat an oven-safe skillet (cast iron preferred) with a bit of oil.
  3. Sear pork on all sides until browned (about 5–7 minutes total).
  4. Transfer skillet to the oven.
  5. Cook for another 10–15 minutes, depending on size.
  6. Use meat thermometer to check doneness.
  7. Remove, rest, and slice.

Tip: While the pork finishes in the oven, make a fresh glaze on the stovetop using leftover (boiled) marinade.

Air Fryer Method (Quick & Easy)

Short on time? The air fryer is perfect.

Instructions:

  1. Preheat air fryer to 400°F.
  2. Place marinated pork in the basket (lined with foil for easier cleanup).
  3. Cook for 18–20 minutes, flipping halfway.
  4. Check internal temperature.
  5. Let rest before slicing and drizzling with glaze.
