Pork Loin Recipe Alton Brown: Brine-Infused Juiciness With Herb Crust

This pork loin recipe delivers restaurant-quality results with a technique I’ve tested in my tiny Boston kitchen more times than I’d like to admit.

The brine is the game-changer, infusing moisture and flavor deep into the meat before cooking. A simple herb crust adds texture and aroma without overpowering the natural pork taste.

After roasting at the right temperature, you’ll have juicy, tender pork with a golden crust that looks as impressive as it tastes. The method is straightforward but precise.

Perfect for Sunday dinners or special occasions when you want to serve something memorable without complicated steps.

Ingredients for Pork Loin Recipe Alton Brown

Pantry staples meet brining magic for that juicy, tender result everyone raves about.

The pork loin is the star, and Whole Foods or local butchers usually have the best cuts. Look for one with a thin fat cap—trimming it yourself ensures even cooking. For the brine, Diamond Crystal kosher salt dissolves faster and seasons more evenly than table salt. I grab mine in bulk at Market Basket (the good stuff, not the iodized kind). Fresh herbs make a difference here—Trader Joe’s has great bundles at a fair price.

No fresh rosemary or thyme? Dried herbs at one-third the amount work in a pinch (just rehydrate in the brine). Swap brown sugar for honey if you’ve got it. Missing Dijon? Whole-grain mustard adds texture, or use yellow mustard with a pinch of turmeric. The wine isn’t critical—chicken broth with a splash of vinegar mimics the acidity. For the crust, panko breadcrumbs add crunch if you’re feeling fancy.

Brine the pork overnight for maximum flavor penetration. Cooked pork keeps well in the fridge for 4-5 days—perfect for meal prep. Freeze leftovers for up to 3 months (slice before freezing for easy portions). The herb crust stays crisp if you reheat in the oven or air fryer.

Step-by-Step Instructions for Brine-Infused Pork Loin With Herb Crust

This method delivers perfectly juicy pork with a fragrant crust every single time.

Step 1: Create the Brine Solution

In a large bowl or pot, combine the 4 cups Water with the 0.5 cup Kosher Salt and 0.25 cup Brown Sugar. Stir until both the salt and sugar are completely dissolved—this ensures even distribution throughout the brine for maximum flavor penetration.

The brine should be at room temperature before adding the pork loin. I always check that no undissolved grains remain at the bottom of the container. This solution will properly season the meat and help it retain moisture during cooking.

Step 2: Brine the Pork Loin

Submerge the 2 lb Pork Loin completely in the brine solution. If your container isn’t quite large enough, you can top it off with a bit more cold water to ensure full coverage. Refrigerate for 12-24 hours—this is the magic window for optimal flavor and texture.

I like to place a plate on top of the pork to keep it fully submerged during the brining process. The pork will absorb the seasoned liquid, resulting in meat that’s flavorful all the way through, not just on the surface. Don’t exceed 24 hours or the texture can become mealy.

Step 3: Prepare and Apply the Herb Crust

Remove the pork loin from the brine and pat it completely dry with paper towels. In a small bowl, combine the 2 tbsp Fresh Rosemary, 2 tbsp Fresh Thyme Leaves, 4 cloves Garlic Cloves, 1 tbsp Black Peppercorns, 1 tsp Ground Coriander, and 1 tsp Ground Fennel Seeds. This aromatic blend creates the signature crust.

Mix the 2 tbsp Dijon Mustard with the 2 tbsp Olive Oil to create a paste, then brush this mixture all over the pork loin. Press the herb mixture onto the mustard-coated pork, ensuring it adheres completely. The mustard acts as a glue for the herbs while adding a subtle tang.

Step 4: Roast to Perfection

Preheat your oven to 375°F. Place the pork loin on a rack in a roasting pan, fat-side up. Roast for 45-60 minutes, or until the internal temperature reaches 145°F on an instant-read thermometer. The crust should be deep golden brown and fragrant.

I check the temperature in the thickest part of the loin, avoiding the bone if present. The pork will continue to cook as it rests, so remove it from the oven just as it hits 145°F. This ensures it won’t overcook while resting.

Step 5: Rest and Deglaze for Serving

Transfer the pork loin to a cutting board and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute throughout the meat. While it rests, place your roasting pan on the stovetop over medium heat.

Add the 0.5 cup Dry White Wine to the pan and scrape up all the browned bits with a wooden spoon. Simmer for 2-3 minutes until slightly reduced. Drizzle this pan sauce over the sliced pork loin when serving for an extra layer of flavor. The sauce should be rich and aromatic, complementing the herb crust perfectly.

Dietary Considerations for pork loin recipe alton brown

Gluten-Free Friendly

This recipe is naturally gluten-free as written, making it safe for anyone with celiac disease or gluten sensitivity. The brine uses simple ingredients like kosher salt, brown sugar, and water, while the herb crust relies on fresh herbs and Dijon mustard—all naturally free from gluten.

Low-Carb Option

For a low-carb version, simply omit the brown sugar from the brine. The pork will still be flavorful and juicy, as the salt and herbs provide plenty of taste. I’ve tested this in my kitchen, and the difference is minimal—honestly, you won’t miss it.

Dairy-Free by Default

There’s no dairy in this recipe, so it’s perfect for anyone avoiding lactose or following a dairy-free diet. The olive oil and herb crust add richness without any butter or cream. Even the pan sauce uses white wine for deglazing, keeping it light and dairy-free.

Sodium Considerations

If you’re watching your sodium intake, reduce the kosher salt in the brine by half. The pork will still be flavorful, especially with the herb crust. I recommend using low-sodium chicken broth for deglazing instead of wine to further cut sodium. 💡

Allergen Notes

This dish is free from common allergens like nuts, eggs, and soy. However, always check your Dijon mustard label—some brands may contain trace amounts of allergens. For complete safety, use certified allergen-free ingredients.

Keto-Friendly

With the brown sugar omitted, this becomes a keto-friendly meal. The pork loin itself is high in protein and low in carbs, and the herb crust adds flavor without adding sugar. Serve with roasted veggies for a complete keto meal. 💪
