Juicy Pork Tenderloin Marinade with Garlic and Herbs

The easiest, most flavorful pork tenderloin marinade you’ll ever try. This pork tenderloin marinade recipe blends sweet and salty elements using BBQ sauce, soy sauce, and garlic to keep your pork juicy and delicious.

Flavorful Pork Tenderloin Marinade

Say goodbye to dry, bland pork tenderloin. This marinade is designed to add moisture, balance of flavor, and an appealing caramelized finish when cooked. Combine the ingredients in minutes and let the pork marinate for a few hours to overnight for best results. It’s ideal for grilling, but also fantastic for baking, air frying, or sous vide.

What is in this pork tenderloin marinade?

This recipe uses just three basic ingredients that most kitchens already have on hand. It’s written for a total of about 2 pounds of pork tenderloin (we used two 1-lb tenderloins).

• Soy sauce: Provides savory, salty umami. Use regular soy, low-sodium soy, or tamari for a gluten-free option.
• BBQ sauce: Adds sweetness and body. Pick a sweeter BBQ sauce to balance the soy, or choose a smokier variety if you prefer a bolder flavor.
• Minced garlic: Fresh or jarred minced garlic brings aromatic depth.

How to Marinate Pork Tenderloin

Preparing the marinade takes less than five minutes. Follow these steps for reliable, flavorful results:

1. Combine the BBQ sauce, soy sauce, and minced garlic in a medium bowl and mix until well combined.
2. Place the pork tenderloin(s) into a baking dish, a gallon-size resealable bag, or a reusable silicone bag.
3. Pour the marinade over the pork, ensuring the meat is fully coated. Remove excess air and seal the bag, or cover the dish tightly.
4. Refrigerate and marinate for 4 to 12 hours for best flavor. If you’re pressed for time, marinate at least 30 minutes.

How long to marinate pork tenderloin

For a noticeable difference in flavor and texture, marinate pork tenderloin at least 4 hours or overnight. If the recipe includes acidic ingredients like citrus or vinegar, limit marinating to 30 minutes to 4 hours to avoid over-tenderizing. This particular marinade does not contain added acid, so it’s safe to marinate longer within the suggested window.

Pork Tenderloin Cooking Methods

This marinade works well with almost any cooking method. Below are reliable methods and target temperatures so you can choose what fits your kitchen and schedule.

• Grilled: Preheat the grill to about 400°F. Grill over direct heat for roughly 12 minutes, turning halfway. Cook until the internal temperature reaches 145°F.
• Baked: Sear the tenderloin in a skillet with butter or oil until browned, then roast at 400°F for 10 minutes. Flip and continue roasting another 12–16 minutes or until it reaches 145°F.
• Instant Pot / Pressure Cooker: Sear on the sauté setting, add a bit of broth, deglaze the pot, and pressure cook on high for about 15 minutes, followed by a natural or quick release per your model’s instructions.
• Air Fryer: Air fry at 400°F for 20–22 minutes, flipping once, and check for a 145°F internal temperature.
• Sous Vide: Vacuum-seal the marinated tenderloin and cook in a 145°F water bath for about 3 hours, then sear briefly in a hot pan or on the grill to develop color.

FAQ

How long should you marinate pork?

We recommend 30 minutes to 12 hours. Longer marinating yields more flavor; overnight is ideal for maximum infusion.

Can you marinate pork tenderloin too long?

If a marinade contains acids like citrus or vinegar, avoid marinating more than 4 hours. This recipe does not include those acids, so marinating up to 12 hours is fine.

How do you tenderize pork tenderloin?

Salt is an effective tenderizer. Sprinkle coarse sea salt on the meat and let it rest for about an hour before rinsing and proceeding with your recipe if desired.

Should pork tenderloin be cooked slow or fast?

Because pork tenderloin is a lean cut, both low-and-slow and hot-and-fast methods can work well depending on the result you want; sous vide or hot searing followed by quick roasting are both great options.

Can I freeze this pork tenderloin in the marinade?

Yes. Freezing the pork in the marinade saves time and locks in flavor. Use a gallon-size resealable bag, remove as much air as possible, label with the date, and freeze for up to 3 months. Thaw completely in the refrigerator before cooking and follow your preferred cooking method.

Ingredients (for about 2 lb. pork tenderloin)

• 1 tablespoon minced garlic
• 3/4 cup BBQ sauce

Instructions

2. Place the pork tenderloin(s) in a baking dish or a resealable bag and pour the marinade over the meat, turning to coat thoroughly.

4. When ready, cook using your preferred method—grill, bake, air fry, pressure cook, or sous vide—until the internal temperature reaches 145°F. Let rest, slice, and serve.
