Recipe Overview

Prep Time: 15 minutes
Cook Time: 25 minutes
Total Time: 40 minutes (plus marinating time)
Servings: 6-8
Dietary Type: Gluten-Free (naturally)

Ingredients

1-2 lb pork tenderloin
½ cup soy sauce
½ cup lime juice
½ cup canola oil (or olive oil)
1-2 tablespoon crushed red pepper flakes (to taste)
1-2 tablespoon garlic, minced (to taste)

Equipment Needed

13″ x 9″ non-metallic pan or large ziplock bag
Grill

Instructions

Prepare the Marinade: In a 13″ x 9″ non-metallic pan (glass or ceramic) or a large ziplock bag, whisk together the soy sauce, lime juice, canola oil (or olive oil), minced garlic, and crushed red pepper flakes. Adjust the amount of garlic and red pepper flakes to your preference. Remember that the flavors will intensify during the marinating process.
Marinate the Pork: Place the pork tenderloin in the marinade, ensuring it is fully submerged. If using a pan, turn the tenderloin to coat all sides. Seal the ziplock bag, removing any excess air. Refrigerate and marinate for at least 4 hours, or preferably overnight. For an even deeper flavor, you can marinate for up to 48 hours. The longer it marinates, the more flavorful and tender the pork will become.
Preheat the Grill: Prepare your grill for low heat. For a gas grill, this means setting the burners to low or medium-low. For a charcoal grill, arrange the coals to create a moderate, even heat. A lower temperature is key to preventing the outside of the pork from burning before the inside is cooked through.
Grill the Tenderloin: Remove the pork tenderloin from the marinade, allowing any excess to drip off. Place the tenderloin on the preheated grill.
Cook and Baste: Grill the pork tenderloin over low heat, turning regularly to ensure even cooking. Baste the tenderloin with the remaining marinade every few minutes. Be cautious when basting, as the marinade may cause flare-ups on the grill.
Check for Doneness: Continue grilling until the internal temperature reaches 160°F (71°C). Use a meat thermometer inserted into the thickest part of the tenderloin to check the temperature. The cooking time will vary depending on the thickness of the tenderloin and the heat of your grill, but it typically takes about 25 minutes.
Rest and Serve: Once the pork tenderloin reaches 160°F, remove it from the grill and let it rest for 5-10 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful result. Slice the tenderloin into ½-inch thick medallions and serve immediately.

Expert Tips & Tricks

Marinating Time: Don’t skimp on the marinating time! The longer the pork marinates, the more flavor it will absorb and the more tender it will become.
Low and Slow: Grilling over low heat is crucial for achieving a perfectly cooked pork tenderloin. This allows the inside to cook through without burning the outside.
Don’t Overcook: Pork tenderloin is lean and can become dry if overcooked. Use a meat thermometer to ensure it reaches an internal temperature of 160°F.
Resting is Key: Allowing the pork to rest before slicing is essential for a juicy and tender result.
Marinade Safety: Never reuse marinade that has been in contact with raw meat. If you want to use the marinade as a sauce, boil it for several minutes to kill any harmful bacteria.
Flavor Boost: For an extra layer of flavor, add a tablespoon of grated ginger or a pinch of smoked paprika to the marinade.

Serving & Storage Suggestions

Serve the grilled pork tenderloin hot off the grill, sliced into medallions. It pairs well with a variety of side dishes, such as grilled vegetables, rice pilaf, or a fresh salad. Garnish with fresh cilantro or a squeeze of lime juice for added brightness.

Leftover pork tenderloin can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm the pork in a skillet over low heat or in the microwave. Be careful not to overcook it, as it can become dry.

For longer storage, you can freeze cooked pork tenderloin for up to 2-3 months. Wrap the pork tightly in plastic wrap and then in aluminum foil to prevent freezer burn. Thaw overnight in the refrigerator before reheating.

Variations & Substitutions

FAQs (Frequently Asked Questions)

Q: Can I use a different type of oil?
A: Yes, you can substitute the canola oil with olive oil or any other neutral-flavored oil. Just be mindful of the smoke point of the oil if grilling over high heat.

Q: How do I know when the pork is done?
A: The best way to determine doneness is to use a meat thermometer. Insert the thermometer into the thickest part of the tenderloin, making sure it doesn’t touch any bone or fat. The pork is done when it reaches an internal temperature of 160°F (71°C).

Q: Can I marinate the pork for longer than 48 hours?
A: While you can technically marinate the pork for longer, it’s generally not recommended. Over-marinating can cause the pork to become mushy.

Q: Can I bake this in the oven instead of grilling?
A: Yes, you can bake the pork in the oven. Preheat your oven to 400°F (200°C). Place the marinated pork tenderloin in a baking dish and bake for 20-25 minutes, or until the internal temperature reaches 160°F.

Q: What should I serve with this pork tenderloin?
A: This pork tenderloin pairs well with a variety of side dishes, such as grilled vegetables, roasted potatoes, rice pilaf, or a fresh salad.
