Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 10 minutes
• Total Time: 20 minutes
• Servings: 4
• Dietary Type: Gluten-Free (check mustard ingredients)

Ingredients

• 1 lb pork tenderloin
• 3 tablespoons mustard, grainy
• 1 tablespoon vegetable oil
• 1 tablespoon rice vinegar
• 2 teaspoons brown sugar
• 2 teaspoons sesame oil
• ¼ teaspoon salt
• ¼ teaspoon pepper
• 2 garlic cloves, minced

Equipment Needed

• Cutting board
• Knife
• Mixing bowl
• Skillet or BBQ grill

Instructions

1. Begin by preparing the pork tenderloin. Use a sharp knife to trim any excess fat from the surface. Excess fat can cause flare-ups on the grill or in the skillet.

2. Now, butterfly the pork tenderloin. To do this, slice the tenderloin lengthwise, almost all the way through, ensuring you don’t cut completely in half. Then, open it up like a book, creating a larger, flatter surface. This will help the tenderloin cook more evenly and absorb the marinade.

3. In a medium-sized mixing bowl, combine the marinade ingredients: 3 tablespoons of grainy mustard, 1 tablespoon of vegetable oil, 1 tablespoon of rice vinegar, 2 teaspoons of brown sugar, 2 teaspoons of sesame oil, ¼ teaspoon of salt, ¼ teaspoon of pepper, and 2 minced garlic cloves. Whisk all ingredients together thoroughly until well combined. The mustard provides a tangy base, while the brown sugar offers a hint of sweetness to balance the flavors. The sesame oil adds a nutty aroma that complements the pork beautifully, and the garlic brings a pungent and savory depth.

4. Place the butterflied pork tenderloin into the bowl with the marinade, ensuring that all surfaces are well coated. Gently massage the marinade into the meat. Let the pork tenderloin stand in the marinade for a minimum of 10 minutes. For a more intense flavor, you can marinate it for up to 4 hours in the refrigerator. If marinating for an extended period, cover the bowl with plastic wrap to prevent the pork from drying out and to avoid contaminating other foods in your refrigerator.

5. Preheat your skillet over medium-high heat or prepare your BBQ grill for medium-high heat cooking. If using a skillet, add a small amount of vegetable oil to prevent sticking.

6. Grill the pork tenderloin in the skillet or on the BBQ for approximately 10 minutes, or until it reaches an internal temperature of 145°F (63°C). Use a meat thermometer to ensure accuracy. The cooking time may vary depending on the thickness of the tenderloin and the heat of your grill or skillet. Turn the tenderloin occasionally to ensure even cooking on all sides. Be careful not to overcook the pork, as it can become dry.

7. Once cooked, remove the pork tenderloin from the skillet or grill and place it on a cutting board. Let it stand for 5 minutes before cutting. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.

8. Finally, cut the pork tenderloin diagonally into thin slices. This enhances the presentation and makes it easier to serve.

Expert Tips & Tricks

• For a richer flavor, use Dijon mustard instead of grainy mustard.
• If you don’t have rice vinegar, apple cider vinegar can be used as a substitute.
• Adjust the amount of brown sugar to your liking, depending on your preference for sweetness.
• To prevent the pork from sticking to the grill, lightly oil the grill grates before cooking.
• For an extra layer of flavor, sprinkle some sesame seeds over the pork before serving.
• Don’t overcrowd the pan when cooking; work in batches to ensure even searing and browning.

Serving & Storage Suggestions

Serve the sliced Mustard Garlic Pork Tenderloin immediately. It pairs beautifully with rice, roasted vegetables, a fresh salad, or mashed potatoes. For an extra touch, drizzle the pan juices over the sliced pork.

Leftover pork tenderloin can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm it in a skillet over low heat or in the microwave. Avoid overheating, as this can dry out the pork. You can also use leftover pork tenderloin in sandwiches, salads, or stir-fries.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of pork for this recipe?
A: While pork tenderloin is the ideal choice due to its tenderness and quick cooking time, you could potentially use pork loin. However, pork loin is a larger cut and may require a longer cooking time.

Q: How do I know when the pork tenderloin is fully cooked?
A: The best way to determine doneness is by using a meat thermometer. Insert the thermometer into the thickest part of the tenderloin. It should reach an internal temperature of 145°F (63°C).

Q: Can I marinate the pork tenderloin overnight?
A: While you can marinate it for a longer period, it’s best not to exceed 4 hours, as the acid in the marinade can start to break down the meat and make it mushy.

Q: What if I don’t have a grill?
A: No problem! You can easily cook the pork tenderloin in a skillet on the stovetop. Just make sure to preheat the skillet and sear the pork on all sides before reducing the heat and cooking it through.

Q: Can I freeze leftover pork tenderloin?
A: Yes, you can freeze leftover pork tenderloin. Wrap it tightly in plastic wrap or place it in an airtight container before freezing. It can be stored in the freezer for up to 2-3 months. Thaw completely before reheating.
