Ingredients for brine recipe for pork tenderloin
Science-backed brine ingredients that transform tough pork into melt-in-your-mouth perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, 1-inch thick slices |
| Kosher Salt 🧂 | ½ cup | Diamond Crystal preferred |
| Granulated Sugar 🍚 | ¼ cup | White or brown sugar |
| Garlic Cloves 🧄 | 6 cloves | Smashed, skin-on preferred |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | Packed, stems removed |
| Black Peppercorns 🌶️ | 1 tbsp | Freshly cracked |
| Fresh Orange Peel 🍊 | ½ cup | Finely shredded, no pith |
| Cold Water 💧 | 4 cups | Filtered preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For post-brine sear |
| Unsalted Butter 🧈 | 2 tbsp | For basting |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
The pork tenderloin is your star—look for center-cut pieces with good marbling, not the skinny ends. Whole Foods or your butcher will have the best quality, but any grocery store carries them. The 1.5 lb is perfect for four servings, but adjust if you're feeding more. Fresh herbs make all the difference here: grab rosemary and thyme with vibrant green leaves—none of that wilted stuff. The garlic should be firm and smell pungent, not musty. For the orange peel, use a vegetable peeler to remove just the zest—no bitter pith. Trader Joe's sells pre-peeled oranges if you're short on time.
No fresh rosemary? Dried works at one-third the amount, but it won't have the same depth. Short on orange peel? A splash of fresh orange juice adds brightness, though it won't replicate the citrus oils. The sugar is non-negotiable—it helps dissolve the salt and adds subtle sweetness. If you're watching sugar, reduce to 2 tbsp but don't skip it entirely. The kosher salt should be Diamond Crystal if you can find it—it dissolves better than table salt. For the olive oil, California extra-virgin brands like Corto or Filippo Berio add the best flavor. And trust me on the butter—full-fat is worth the extra minute to melt it properly for basting.
This brine keeps for up to 3 days in the fridge if you want to prep ahead. The pork stays fresh for 2 days in the brine—don't exceed that or it'll get mushy. After cooking, slice against the grain for maximum tenderness. Leftovers reheat beautifully in a 350°F oven for 10 minutes with a splash of water. I always make extra brine—it's perfect for brining chicken or even grilling vegetables later. Store the extra in a sealed jar for up to 1 week.

Step-by-step instructions for brining pork tenderloin
Transform your pork tenderloin into a juicy, pink-centered masterpiece with this foolproof brining method.
Prepare the Herb-Infused Brine
In a large bowl, combine the 4 cups cold water, 0.5 cup kosher salt, and 0.25 cup granulated sugar. Stir until completely dissolved—this ensures even distribution of flavor and moisture. Add the 6 smashed garlic cloves, 0.25 cup chopped fresh rosemary, 0.25 cup packed fresh thyme leaves, 1 tablespoon freshly cracked black peppercorns, and 0.5 cup finely shredded fresh orange peel. Mix gently to infuse the brine with aromatic depth.
Here's the thing—this isn't just a saltwater bath. The herbs and citrus create a complex flavor profile that penetrates the meat while keeping it tender. Let the brine steep for 10 minutes at room temperature so the aromatics fully release their oils. This step makes all the difference in the final taste.
Submerge the Pork in the Brine
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this helps the brine cling to the meat rather than pooling on the surface. Place the tenderloin in a resealable plastic bag or large container and pour the herb-infused brine over it. Make sure the pork is fully submerged, turning it gently to ensure even contact with the liquid. Seal the bag or cover the container and refrigerate for at least 4 hours or up to overnight.
I know it seems counterintuitive to brine overnight when you're eager to cook, but this extended time guarantees maximum moisture retention and flavor penetration. The acidity from the orange peel and sugar helps tenderize the meat while the salt breaks down proteins for that melt-in-your-mouth texture. Don't skip this—it's the secret to your juicy, pink-centered result.
Sear and Finish the Brined Pork
Remove the pork from the brine and pat it dry once more—this final drying step is crucial for that perfect crust. Heat 2 tablespoons extra-virgin olive oil in a large skillet over medium-high heat until shimmering. Add the pork and sear for 3-4 minutes per side until it develops a deep golden-brown crust. The internal temperature should reach 145°F at this point.
Here's where it gets fun—reduce the heat to medium and add 2 tablespoons unsalted butter. Tilt the pan slightly and spoon the melted butter over the pork for 2 minutes, basting it continuously. This creates a glossy finish while keeping the interior moist. You'll know it's ready when the butter turns golden and fragrant—this is your signal that the pork is nearly done.
Rest and Serve with Garnish
Transfer the pork to a cutting board and let it rest for 10 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, preventing them from pooling on your plate. Use a sharp knife to cut the pork into ½-inch thick slices against the grain for maximum tenderness.
Garnish each serving with 0.125 cup chopped fresh parsley and serve immediately. The result should be pork that's juicy, pink in the center (thanks to the precise brining time), and bursting with herbaceous, citrusy flavor. Each bite should be tender enough to pull apart with minimal effort, with a crispy exterior that contrasts beautifully with the moist interior.
Pro Tips For Making Brine Recipe For Pork Tenderloin
- USE COLD WATER FOR BRINING: I learned this the hard way—warm water makes the pork absorb brine unevenly and turns it mushy. Fill your container with ice water first, then add the brine mixture and pork. The cold keeps the meat firm while it soaks up those flavors evenly.
- CHOP GARLIC FINE, NOT MINCED: I used to mince garlic for the brine, thinking it would blend better, but it turns to paste and clumps. Instead, give those cloves a few sharp chops with a chef’s knife—big enough to release flavor but small enough to stay whole. Trust me, you’ll taste the difference when you sear that tenderloin.
- DON’T SKIP THE SUGAR RINSE: After brining, give the pork a quick rinse under cold water and pat it very dry. The sugar in the brine caramelizes fast when searing, so this step keeps your crust crisp instead of sticky. (Yes, even if you’re impatient like me—give it 5 minutes.)
- BRINE FOR 2 HOURS, NOT OVERNIGHT: Pork tenderloin is lean and absorbs moisture fast—leave it in the fridge for more than 2 hours, and you’ll end up with soggy meat. Two hours is plenty to season deeply without turning it into a waterlogged sponge. Set a timer, and stick to it.
Storing and reheating your leftovers
Refrigerator Storage
After brining, store your pork tenderloin in an airtight container with any leftover brine (up to 1 cup) to maintain moisture. Keep it refrigerated for up to 2 days—the brine actually enhances preservation by inhibiting bacterial growth. I like using glass Pyrex containers because they don’t absorb odors and allow me to see the meat clearly. Just
Freezer Prep
For longer storage, freeze the brined pork tenderloin in a freezer-safe bag with ¼ cup extra brine to prevent drying. Flatten it slightly to save space and remove as much air as possible to avoid freezer burn. It stays excellent for up to 3 months—just thaw overnight in the fridge before cooking. I’ve found that brined pork freezes better than unbrined because the salt helps retain moisture during thawing. ❄️
Reheating Leftovers
Slice your cooked pork tenderloin and reheat portions in a skillet over medium heat with 1 tablespoon butter for 2-3 minutes until warmed through. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals on 50% power until reaching 165°F.
The brining ensures reheated slices stay juicy—no dryness here! 🔥
Make-Ahead Brine
Prep the brine 2 days ahead and store it in the fridge—it keeps perfectly in a sealed jar. The pork can also soak in the fridge for up to 24 hours before cooking, giving you flexibility for meal planning.
I often brine my pork the night before and cook it the next morning for a stress-free weeknight dinner. The flavors deepen over time, so don’t rush this step! ⏰
Portion Control
Divide cooked pork into ½-inch slices and store in single-serving containers for easy reheating. This prevents overcrowding in the fridge and makes it simple to grab just what you need. I portion mine into small glass containers with a sprinkle of fresh parsley to keep it looking fresh.
Label each with the date to track freshness—brined pork stays safe for 4 days in the fridge. 📅

Frequently asked questions
Why does brining pork tenderloin make it juicier?
The salt in the brine breaks down muscle proteins, allowing them to retain more moisture during cooking. The sugar and citrus help tenderize while the herbs infuse flavor—all working together to create a melt-in-your-mouth texture. This method adds 15-20% more moisture compared to unbrined pork, ensuring every bite stays succulent.
Can I use a dry brine instead of wet brine?
Yes! For a dry brine, mix 1 tbsp kosher salt with 1 tsp sugar and rub it all over the pork. Let it sit uncovered in the fridge for 12-24 hours before cooking. The dry method works well for thicker cuts, but wet brine gives more even flavor distribution. Both methods prevent dryness—choose based on your preference!
What if my pork tenderloin turns out dry?
Overcooking is the most common cause. Use a meat thermometer and remove the pork when it hits 145°F (it will rise to 150°F while resting). Brined pork should never be cooked beyond 155°F. If it's slightly dry, try slicing thinly and serving with a pan sauce made from the drippings and butter.
How long can I brine pork tenderloin?
For best results, brine for 4-24 hours. Beyond 24 hours, the meat can become overly salty or mushy. The 12-hour mark is ideal for maximum flavor without compromising texture. If you're short on time, even 2 hours will help, though overnight brining delivers the juiciest results.
Can I reuse the brine?
No, never reuse pork brine—it contains raw meat juices that may harbor bacteria. However, you can repurpose the liquid (without meat) for brining vegetables like zucchini or asparagus. Strain out the herbs and use it within 2 days for other non-meat applications. The citrus and herbs work beautifully on plant-based dishes too!
