This Pork Tenderloin Marinade turns a simple cut of meat into something truly crave-worthy. A quick mix of pantry staples, a little time in the fridge, and you get pork that is juicy all the way through with a deep, savory flavor. I started making this when dry, tasteless pork kept showing up at dinner, and this marinade fixed that problem for good.
The combination of soy sauce, lemon juice, brown sugar, and fresh garlic works on every level. It is savory, a little sweet, and just tangy enough to keep things interesting. It works on the grill, in the oven, or in the air fryer, so it fits whatever kind of night you are having. Make it your own!

Ingredients for Pork Tenderloin Marinade
I always keep these pantry staples on hand because this pork tenderloin marinade comes together in about five minutes. The ingredient list is simple but every single item pulls its weight.
- 3 tbsp olive oil – I recommend extra virgin for the richest flavor
- 3 tbsp low sodium soy sauce – My preference is low sodium so you stay in control of the saltiness
- 3 tbsp lemon juice (freshly squeezed works best)
- 2 tbsp brown sugar (light or dark both work fine)
- 1 tbsp Dijon mustard
- 6 cloves garlic, minced – In my experience, fresh minced garlic makes a much bigger difference here than garlic powder
- 1 tsp dried oregano or Italian seasoning
- 1/2 tsp salt
- 1/2 tsp black pepper
- 1 to 1.5 lbs pork tenderloin, silver skin trimmed
Step-by-Step Instructions
I recommend reading through all three cooking options before you start so you can pick the method that fits your schedule best. Each one produces juicy, flavorful results.
Step 1: Whisk together the olive oil, soy sauce, lemon juice, brown sugar, Dijon mustard, minced garlic, oregano, salt, and pepper in a small bowl until fully combined. If you want to brush the pork during cooking, set aside 2 tablespoons of marinade now in a separate clean dish before it touches the raw meat.
Step 2: Trim the silver skin from the pork tenderloin using a sharp knife. Silver skin does not break down during cooking and will make the meat chewy if left on. Place the trimmed pork in a large zip-top bag and pour the marinade over it. Seal and turn to coat evenly.
Step 3: Refrigerate for at least 1 hour and up to 12 hours. Do not go beyond 24 hours because the lemon juice will start to break down the texture of the meat. When ready to cook, remove the pork and discard the used marinade from the bag.
Step 4 (To Grill): Heat the grill to medium heat. Grill with the lid closed for 15 to 25 minutes, turning every few minutes, until the internal temperature reads 145 degrees F on a meat thermometer. Brush with the reserved clean marinade during the last few minutes of cooking. Rest 5 minutes before slicing.
Step 4 (To Bake): Preheat the oven to 400 degrees F. Heat 1 tablespoon of olive oil in an oven-safe skillet over medium-high heat. Sear the pork on all sides for 1 to 2 minutes per side until golden brown. Transfer the skillet to the oven and bake for 20 to 25 minutes until the internal temperature reaches 145 degrees F. Rest 5 minutes before slicing.
Step 4 (To Air Fry): Preheat the air fryer to 380 degrees F for 5 minutes. Air fry the pork for 10 minutes, then flip and cook for an additional 8 to 16 minutes until the internal temperature reaches 145 degrees F. Rest 5 minutes before slicing.
Best Sides to Serve with Pork Tenderloin
Pork tenderloin has a mild, savory flavor that welcomes both light and hearty sides on the plate.
Garlic Roasted Vegetables: A sheet pan of roasted veggies adds color, crunch, and a savory bite that balances the richness of the marinade without any extra fuss.
Easy Chicken Breast and Green Beans: If you are feeding a bigger crowd, this simple green bean side brings freshness and a light texture that pairs nicely alongside the pork.
Creamy Garlic Sauce Potatoes: Buttery, garlicky potatoes are a natural partner for the lemon-soy flavors in this marinade and make the whole plate feel satisfying and complete.
Cold Pasta Salad: A chilled pasta salad is a refreshing contrast to the warm, juicy pork. It is also easy to make ahead, which takes the pressure off dinner time.

Broccoli and Mushroom Stir Fry: The earthy, savory stir fry is a quick and healthy side that rounds out the plate with vegetables and a bit of umami depth that echoes the soy notes in the marinade.
Easy Baked Honey Dijon Chicken: If you love the Dijon mustard flavor in this marinade, this baked honey Dijon chicken uses the same flavor profile and makes a great companion dish when you are cooking for a larger group.
How to Store and Reheat Leftover Pork Tenderloin
Store cooked pork tenderloin in an airtight container in the refrigerator for up to 4 days. To freeze, slice the pork first and lay the pieces flat in a freezer-safe bag. It keeps well for up to 3 months in the freezer.
To reheat, I recommend wrapping slices loosely in foil and warming them in a 300 degree F oven for about 10 minutes. This method keeps the pork from drying out. You can also warm slices quickly in a skillet over medium-low heat with a splash of chicken broth to add moisture back.
Pro tip: leftover sliced pork is great in grain bowls, wraps, or on top of a simple salad the next day. The marinade flavors actually deepen overnight, so day-two leftovers taste just as good as the first serving.
FAQs
Can I use this marinade on other cuts of pork?
Yes. This marinade works well on pork chops and pork loin too. Thicker cuts may need longer cook times, so always use a meat thermometer and cook to 145 degrees F internal temperature.
Do I have to sear the pork if I am baking it?
Searing is not required, but it makes a real difference. Those 1 to 2 minutes per side in a hot skillet create a golden crust that locks in the juices and adds flavor you cannot get from baking alone.
Can I make the marinade ahead of time?
Yes. You can mix the marinade up to 3 days in advance and store it in a sealed jar in the refrigerator. Just give it a good stir before using since the olive oil may separate slightly when chilled.
