Brine Recipe For Pork Tenderloin: Juice-Retaining Prep for Perfect Roasts

This simple brine transforms pork tenderloin into perfectly juicy, tender roasts every time. The salt solution breaks down muscle fibers while sugar balances the flavor, ensuring meat that stays moist through cooking.

I developed this method after years of dry, overcooked tenderloins. The right ratio of water, salt, and sugar makes all the difference, with optional herbs adding depth without overpowering the pork’s natural sweetness.

The process takes 15 minutes of active prep, then just time in the fridge. A 12-hour soak guarantees maximum moisture retention, so your final dish is never tough or stringy.

Use this for roasting, grilling, or smoking. The results will speak for themselves.

Nine ingredients for a brine that guarantees juicy, tender pork every single time.

The salt is the workhorse here. Diamond Crystal kosher salt dissolves fastest and gives consistent results—table salt works but use half the amount. Brown sugar adds balance; light or dark doesn’t matter much. Most grocery stores carry everything you need, but Whole Foods has great bulk options for spices if you want to stock up.

No brown sugar? White sugar or maple syrup works fine. Fresh out of rosemary or thyme? Dried herbs at half the quantity will do the trick. Juniper berries are optional but add a nice depth—skip them if you don’t have them. The peppercorns and bay leaves are classic, but red pepper flakes can add a little heat if that’s your thing.

This brine keeps in the fridge for 1 week if you make extra. Store in a sealed container away from raw meat. For best results, use within 3 days of making it.

Step-by-Step Instructions for Pork Tenderloin Brine

This method guarantees juicy, flavorful results with minimal effort and maximum impact.

Step 1: Bloom the Aromatics in Hot Water

In a medium saucepan, combine 1 cup of the 4 cups Water with the 0.5 cup Kosher Salt and 0.25 cup Brown Sugar. Heat over medium-high heat just until the salt and sugar dissolve completely—this usually takes 2-3 minutes.

Remove from heat and add the 1 tbsp Black Peppercorns, 2 whole Bay Leaves, 2 tbsp Fresh Rosemary, 1 tbsp Fresh Thyme, 4 cloves Garlic Cloves, and 1 tsp Juniper Berries. Stir well and let steep for 5 minutes—this extracts maximum flavor from the herbs and spices.

Step 2: Cool the Brine Completely

Stir the remaining 3 cups Water into the warm brine mixture. This rapidly brings the temperature down. Now, let the entire mixture cool to room temperature—this is critical for food safety and proper brining.

I speed this up by placing the saucepan in an ice bath and stirring occasionally. You’ll know it’s ready when the brine feels cool to the touch, usually after 15-20 minutes. Never add pork to warm brine—it can start cooking the meat unevenly.

Step 3: Submerge the Pork in the Brine

Place your pork tenderloin in a large resealable bag or non-reactive container. Pour the cooled brine over the meat, ensuring it’s completely submerged. If using a bag, squeeze out as much air as possible before sealing.

For even brining, I like to use a zip-top bag and lay it flat in the refrigerator, flipping it halfway through. This ensures all surfaces of the pork make constant contact with the brine.

Step 4: Brine for Optimal Tenderness

Refrigerate the pork in the brine for 12 to 24 hours. This is the sweet spot for tenderloin—long enough to deeply season and tenderize the meat without making it overly salty.

I find 18 hours gives the best balance of flavor and texture. The pork will look slightly plumped when it’s done brining, which means the solution has properly penetrated the meat fibers.

Step 5: Rinse and Pat Dry Before Cooking

Remove the pork from the brine and discard the liquid. Give the tenderloin a quick rinse under cold water to remove any clinging herbs or excess salt on the surface. This prevents the exterior from becoming too salty during cooking.

Pat the pork extremely dry with paper towels. This is crucial for achieving a good sear later. The surface should feel slightly tacky but not wet. Now your pork is ready for roasting, grilling, or any cooking method you prefer.

Pro Cooking Tips for Perfect Results

Salt Selection Matters

I always use Diamond Crystal kosher salt for brining—it dissolves faster than table salt and gives consistent results. If you only have table salt, use half the amount by volume. The right salt makes all the difference in flavor penetration. 💪

Temperature Control

Never add pork to warm brine—it can start cooking the meat unevenly. I cool my brine in an ice bath while stirring, which brings it to room temperature in 15-20 minutes. This ensures food safety and proper brining.

Submersion Technique

Use a zip-top bag and lay it flat in the fridge for even brining. Squeeze out all air before sealing, and flip the bag halfway through. This guarantees all surfaces of the pork make constant contact with the brine.

Perfect Brining Time

For pork tenderloin, 12-24 hours is ideal. I find 18 hours gives the best balance of flavor and texture. The meat will look slightly plumped when ready, meaning the solution has fully penetrated.

Drying for Better Sear

After brining, rinse the pork quickly under cold water to remove excess salt. Pat it extremely dry with paper towels—the surface should feel slightly tacky. This step is crucial for achieving a perfect sear later.

Equipment Recommendation

For best results, use a large resealable bag or non-reactive container. I prefer bags because they allow you to squeeze out air and maximize contact with the brine. Avoid metal containers, as they can react with the salt.
