Recipe Overview

• Prep Time: 5 minutes (plus marinating time)
• Cook Time: 35-40 minutes
• Total Time: 40-45 minutes (plus marinating time)
• Servings: 4
• Yield: 1 tenderloin
• Dietary Type: Gluten Free (if using gluten-free soy sauce)

Ingredients

• 1/2 cup soy sauce
• 1/4 cup sugar
• 2 tablespoons ketchup
• 1 (1 lb) pork tenderloin

Equipment Needed

• Large Ziploc bag
• 13 x 9 inch baking dish
• Saucepan (optional, for thickening marinade)
• Meat thermometer

Instructions

1. In a large Ziploc bag, combine the soy sauce, sugar, and ketchup. Close the bag securely and shake to combine.
2. Add the pork tenderloin to the bag. Seal the bag, pressing out any excess air, and turn the bag to coat the tenderloin evenly in the marinade.
3. Marinate in the refrigerator for at least overnight, but preferably longer (up to 24-36 hours) for maximum flavor penetration. Turn the bag occasionally to ensure even marinating.
4. Preheat your oven to 425°F (220°C).
5. Grease a 13 x 9 inch baking dish.
6. Remove the pork tenderloin from the marinade and place it in the prepared baking dish.
7. (Optional) Pour the remaining marinade into a saucepan. Bring it to a boil over medium heat, then whisk in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) to thicken it into a sauce. Reduce heat and simmer for a few minutes until desired consistency is reached.
8. Bake the pork tenderloin, uncovered, at 425°F (220°C) for 35-40 minutes, or until a meat thermometer inserted into the thickest part of the tenderloin reads 160°F (71°C).
9. Remove the pork tenderloin from the oven and let it rest for 5 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
10. Slice the pork tenderloin and serve with the thickened teriyaki sauce, if you made it.

Expert Tips & Tricks

• Marinating is key: Don’t skimp on the marinating time! The longer the pork sits in the marinade, the more flavorful and tender it will become. Aim for at least 8 hours, or even better, overnight.
• Don’t overcrowd the pan: Ensure the pork tenderloin has enough space in the baking dish for even cooking. Overcrowding can lead to steaming instead of browning.
• Use a meat thermometer: A meat thermometer is your best friend when cooking pork. It ensures that the pork is cooked to a safe internal temperature (160°F/71°C) without overcooking and drying it out.
• Resting is essential: Letting the pork rest for 5 minutes after cooking is crucial for retaining its juices. Tent it loosely with foil to keep it warm.
• Thickening the marinade: Don’t throw away the leftover marinade! Boiling and thickening it creates a delicious sauce to drizzle over the sliced pork. Be sure to boil it for food safety.
• Grilling Alternative: As noted in the original recipe, you can absolutely grill this tenderloin! Preheat your grill to medium-high heat. Grill the tenderloin for about 15-20 minutes, turning occasionally, until the internal temperature reaches 160°F (71°C). Watch carefully to avoid burning due to the sugar in the marinade.

Serving & Storage Suggestions

Serve this Teriyaki Pork Tenderloin with a side of rice or quinoa to soak up the delicious sauce. Steamed vegetables like broccoli, green beans, or asparagus make excellent accompaniments. For a more complete meal, consider adding a simple salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the microwave or oven until heated through. For the best results, slice the pork before reheating to prevent it from drying out.

I do not recommend leaving cooked pork at room temperature for more than two hours.

You can also freeze cooked Teriyaki Pork Tenderloin for up to 2-3 months. Wrap it tightly in plastic wrap and then foil to prevent freezer burn. Thaw overnight in the refrigerator before reheating.
