Ingredients for pork tenderloin brine
Precision-crafted ingredients transform tough pork into melt-in-your-mouth perfection through science-backed brining.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥓 | 1 ½ lb | Center-cut, trimmed of silver skin |
| Diamond Crystal Kosher Salt 🧂 | ¾ cup | For precise brine concentration |
| Granulated White Sugar 🍚 | ½ cup | Balances salt for flavor |
| Fresh Garlic Cloves 🧄 | 8 cloves | Peeled, smashed for intense flavor |
| Fresh Rosemary Sprigs 🌿 | 4 sprigs | Freshly cut, aromatic |
| Fresh Thyme Sprigs 🌿 | 4 sprigs | Freshly cut, lemony notes |
| Black Peppercorns 🌶️ | 1 tbsp | Freshly cracked, coarse grind |
| Bay Leaves 🍃 | 2 whole | Dried, high-quality preferred |
| Ice Water 💧 | 4 cups | Chilled for proper brine temp |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For post-brine searing |
| Fresh Lemon Juice 🍋 | 2 tbsp | Brightens final presentation |
The pork tenderloin must be center-cut and trimmed of silver skin for even cooking—ask your butcher to source it for you. Diamond Crystal kosher salt is essential for accurate brine concentration; other salts require adjustment. Fresh herbs and aromatics elevate the flavor profile beyond basic brines. Whole Foods or high-end grocery stores carry premium dried bay leaves, while fresh rosemary and thyme should be vibrant green with no wilting. The ice water ensures the brine stays at an optimal 50°F, crucial for proper meat penetration without over-salting.
Substitutions must maintain balance: Morton kosher salt works but requires 10% more volume. Swap sugar for brown sugar for depth, though it may darken the meat slightly. Dried herbs should be used at one-third the amount of fresh. No fresh garlic? Garlic powder at half the quantity suffices, though texture differs. For a dairy-free option, omit the optional buttermilk rinse and use lemon juice instead. The brine will keep in the refrigerator for up to 3 days—strain and reuse for subsequent batches.
Store unused brine in an airtight container for up to 3 days in the refrigerator. The brined pork tenderloin should rest uncovered on a wire rack for 15-20 minutes post-cooking to maintain crispness. For meal prep, portion into vacuum-sealed bags with a splash of extra-virgin olive oil to retain moisture for up to 4 days. Reheat gently in a skillet or oven to preserve tenderness.

Step-by-step instructions for pork tenderloin brine recipe
Here's the precise method to transform your pork tenderloin into melt-in-your-mouth perfection.
Prepare the Brine Mixture
In a large non-reactive container, combine the 4 cups ice water, 0.75 cup Diamond Crystal kosher salt, and 0.5 cup granulated white sugar. Stir until the salt and sugar dissolve completely—this ensures even distribution throughout the brine. The ice water prevents the pork from cooking prematurely in the salt solution.
Next, add the 8 cloves fresh garlic cloves (smashed with the flat side of a knife), 4 sprigs fresh rosemary sprigs, 4 sprigs fresh thyme sprigs, 1 tablespoon black peppercorns, and 2 whole bay leaves. The herbs and spices will infuse the meat with complex aromatics during the brining process. Let the mixture steep for 15 minutes at room temperature, allowing the flavors to meld before adding the pork.
Submerge the Pork Tenderloin
Rinse the 1.5 lb pork tenderloin thoroughly under cold water and pat it completely dry with paper towels. This step is critical—any moisture left on the surface will dilute the brine's effectiveness. Submerge the pork in the prepared brine, ensuring it is fully covered. Use a plate or weight to keep it submerged if needed.
Transfer the container to the refrigerator and brine for 12 to 24 hours. The longer brining time (up to 24 hours) yields the most tender results, but even 12 hours will noticeably improve texture. The cold temperature ensures the pork absorbs the brine evenly without cooking.
Remove and Pat Dry
After brining, remove the pork tenderloin and discard the brine. Rinse the pork briefly under cold water to remove any excess salt crystals, then pat it extremely dry with fresh paper towels. This step is essential for achieving a perfect sear—moisture on the surface will steam the meat instead of browning it.
Let the pork sit at room temperature for 30 minutes before cooking. This allows the surface to dry further and ensures even cooking from edge to center. The pork should feel cool to the touch when you handle it.
Sear and Finish
Heat a heavy skillet over medium-high heat and add 2 tablespoons extra-virgin olive oil. Once the oil shimmers, carefully place the pork tenderloin in the pan. Sear for 2 to 3 minutes per side until the exterior develops a deep golden-brown crust. The pork is ready to flip when it releases easily from the pan.
Transfer the pork to a preheated 400°F oven and roast for 15 to 20 minutes, or until the internal temperature reaches 145°F at the thickest part. The pork should feel firm to the touch but still slightly springy. Remove from the oven and let it rest for 10 minutes before slicing.
Serve with Bright Finishing Touches
Slice the pork tenderloin into ½-inch thick medallions and arrange on a serving platter. Drizzle with 2 tablespoons fresh lemon juice and garnish with additional fresh rosemary and thyme sprigs for a vibrant finish. The acidity of the lemon juice cuts through the richness of the pork, enhancing its natural flavors.
Serve immediately, ensuring each slice is juicy and tender with a crisp exterior. The brining process guarantees moisture retention, while the sear and roast create a perfect balance of textures. This method delivers pork tenderloin that rivals the finest restaurant cuts.
Pro Tips For Making Pork Tenderloin Brine
- USE COLD BRINE: The fridge is your friend here—pour that brine over ice cubes first, then add the pork. Cold brine penetrates faster and keeps the meat from cooking prematurely while it soaks. I learned this the hard way after pulling out rubbery tenderloin that had warmed up too much in a lukewarm bath.
- SMASH GARLIC CLOVES: Skip the minced garlic in the brine—it turns to mush and makes the liquid cloudy. Instead, bruise 3-4 cloves with the flat side of your knife or a rolling pin before adding them whole. The aroma infuses without turning the brine into garlic soup.
- BRINE LONGER, NOT SHORTER: Two hours is the absolute minimum, but three gives you that melt-in-your-mouth texture. I used to cut it to 90 minutes when I was rushed, and the results were noticeably tougher. Trust me, the extra hour makes a real difference—especially for thicker cuts.
- DRY THE MEAT WELL: Pat that tenderloin thoroughly with paper towels after brining—no half-measures. Wet spots turn to steam in the pan, making the crust limp instead of crisp. I skip this step sometimes, and the difference in sear quality is frustratingly obvious.

Frequently asked questions
Can I use a shorter brining time for pork tenderloin?
A 12-hour brine will still improve tenderness, but the 24-hour maximum delivers the most dramatic results. For quick prep, try a 4-6 hour wet brine (double the salt to 1.5 cups) or a 1-hour dry brine (coat pork with 1 tablespoon salt per pound and refrigerate uncovered). The texture won't be as ultra-tender, but it'll still be better than unbrined.
What's the best way to store brined pork tenderloin?
Cook the brined pork immediately for best results, but you can refrigerate it for up to 2 days in an airtight container. For longer storage, vacuum-seal the cooked pork with 1 teaspoon olive oil per portion—it stays tender for 4-5 days. Never refreeze after thawing. The brine enhances moisture retention, so reheating works well in a skillet or oven at 350°F.
Can I substitute brown sugar in the brine?
Yes, but expect a slightly darker exterior and deeper molasses notes. Use the same 0.5 cup amount, though it may make the pork slightly softer. For a balanced substitution, reduce to 0.4 cup brown sugar and add 1 teaspoon honey to maintain the original flavor profile. The sugar's caramelization works beautifully with the sear, so it's a worthwhile experiment!
Why does my brined pork turn out dry?
Overcooking is the most common culprit—pork tenderloin's small size cooks quickly! Use a meat thermometer and stop at 145°F internal temp. Other issues: not patting dry before searing (steaming instead of browning), skipping the rest (always rest 10 minutes), or using a lean cut without fat. For extra insurance, brine for 24 hours and baste with butter during roasting to lock in moisture.
Can I make this recipe in a slow cooker?
After brining and searing, transfer the pork to a slow cooker with ¼ cup chicken broth and cook on Low for 3-4 hours or High for 1.5-2 hours. The moist environment prevents drying, and the slow cooking enhances tenderness. Finish with a quick pan sear before serving for that restaurant-quality crust. The herbs and garlic will infuse beautifully during the long cook.
