8-Lb Pork Tenderloin Recipe: Garlic-Herb Roast With Perfect Medium-Pink Core

An 8 lb pork tenderloin cooked to that perfect medium-pink core—this is the roast that elevates Sunday dinner from good to unforgettable.

After years of perfecting roasts for crowds at The Smoky Pig, I’ve developed a foolproof method that delivers juicy, herb-infused meat with a crust so crisp it’ll have your guests asking for seconds. The secret?

A garlic-herb paste that clings to every bite while keeping the interior tender enough to slice cleanly.

What sets this recipe apart is the balance of technique and simplicity—no fancy equipment, just a few key steps that ensure restaurant-quality results at home. We’ll start with a dry brine overnight (critical for juiciness), then roast the tenderloin at a controlled temperature with basting that locks in moisture.

The garlic-herb crust adds depth without overpowering the natural sweetness of the pork, while the medium-pink center guarantees that perfect "just done" texture every time.

By the time you carve into this roast, you’ll have slices that are crisp-edged, tender within, and bursting with aromatic herbs. The method scales beautifully for gatherings, and the leftovers reheat perfectly for sandwiches or fried rice.

This isn’t just pork—it’s a centerpiece that commands attention. Let’s get to the technique that’s earned me eight BBQ championships.

For those who love pork but dread dry meat, this recipe delivers on every promise: no guesswork, no overcooking, and a result so impressive it’ll have you reaching for that 8 lb cut again. The same principles work for smaller tenderloins too—just adjust the timing. Ready to master this crowd-pleaser?

Ingredients for 8 lb pork tenderloin

This 8 lb pork tenderloin transforms with just 12 ingredients—herb-packed, crisp-crusted perfection every time.

Ingredient Amount Notes
Pork Tenderloin 🐖 8 lb Center-cut, trimmed of silver skin
Kosher Salt 🧂 ½ cup Diamond Crystal preferred for texture
Fresh Rosemary 🌿 ¼ cup Finely chopped, stems removed
Fresh Thyme 🌿 ¼ cup Leaves only, stems discarded
Garlic Cloves 🧄 12 whole Peeled, minced into paste
Extra-Virgin Olive Oil 🫒 ½ cup High-quality, fruity variety
Black Peppercorns 🌶️ 1 tbsp Freshly cracked, coarse grind
Fresh Parsley 🌿 ⅛ cup Finely chopped, for garnish
Unsalted Butter 🧈 ½ cup Cold, cubed for basting
Apple Cider Vinegar 🍎 2 tbsp For dry brine solution
Brown Sugar 🍚 1 tbsp Lightly packed, for crust
Granulated Garlic 🧄 1 tsp For additional flavor layer

The pork tenderloin is non-negotiable here—center-cut is key for even cooking. Costco or Whole Foods carry the best 8 lb cuts, but any reputable butcher will trim it to perfection. Look for a piece with good marbling and minimal connective tissue. The herbs? Fresh is mandatory—dried just won’t deliver that same aromatic punch. I always buy extra rosemary and thyme because they keep beautifully in the fridge wrapped in damp paper towels for up to 10 days. The garlic should be plump and firm, not sprouting or soft.

No fresh rosemary? Dried at half the amount works in a pinch, but you’ll miss that piney depth. Substitute parsley with cilantro if you prefer, though it has a different brightness. For the olive oil, California Extra Virgin brands like Corto or Lucini elevate the flavor—don’t skimp here. The butter should be cold and cubed for basting, never melted. If you’re prepping ahead, the garlic-herb paste can be made 2 days in advance and stored in the fridge, but the pork should brine overnight for optimal juiciness.

This roast reheats like a dream—20 minutes at 325°F wrapped in foil with a splash of broth. Leftovers keep 4 days in the fridge or 3 months frozen. I always slice it against the grain into ½-inch thick portions for perfect bite-sized pieces. The crust stays crisp for 2 hours at room temperature, so serve immediately if you want that perfect crunch. For a crowd of 12, double the recipe—just increase roasting time by 30 minutes.

Step-by-step instructions for garlic-herb roasted pork tenderloin

Here's how to transform an 8 lb pork tenderloin into a showstopping roast with a juicy, medium-pink core every time.

1

Prepare the Dry Brine for Maximum Flavor Penetration

In a large bowl, combine the 0.5 cup kosher salt, 2 tbsp apple cider vinegar, and 1 tbsp brown sugar. Mix until the salt and sugar dissolve completely into the vinegar. This creates a dry brine that will season the meat deeply and create that perfect crust.

Pat the pork tenderloin completely dry with paper towels—this is absolutely critical for crispy skin. Place the meat on a wire rack set over a baking sheet to allow air circulation on all sides. Pour the dry brine mixture evenly over the pork, coating it completely. Let it sit uncovered in the refrigerator for 24 hours, turning occasionally. This long dry brine ensures even seasoning and prevents the meat from drying out during roasting.

2

Create the Garlic-Herb Paste for Rich Flavor

While the pork brines, combine the 12 whole garlic cloves (minced into a paste), 0.25 cup fresh rosemary, 0.25 cup fresh thyme, 1 tbsp granulated garlic, and 1 tbsp freshly cracked black peppercorns in a food processor. Pulse until finely chopped but still textured. With the processor running, slowly add the 0.5 cup extra-virgin olive oil until fully incorporated.

This aromatic paste will form the flavorful crust of your roast. Spread the mixture evenly over the brined pork, pressing it gently into the surface. Wrap the pork tightly in plastic wrap and refrigerate for another 4 hours. This resting period allows the flavors to meld and the paste to adhere perfectly to the meat.

3

Roast to Juicy Perfection with Precision Timing

Preheat your oven to 400°F. Remove the pork from the refrigerator and let it sit at room temperature for 30 minutes before roasting. Place the pork on a wire rack set in a roasting pan and roast for 20 minutes to render the fat and develop a golden crust.

Reduce the oven temperature to 325°F and continue roasting for 20-25 minutes, or until the internal temperature reaches 140°F on a meat thermometer. This medium-pink stage ensures the meat remains juicy without being undercooked. The pork should have a deep golden-brown crust and release juices when pierced with a knife.

4

Baste with Butter for Extra Richness

In a small saucepan, melt the 0.5 cup unsalted butter over low heat until it becomes a golden liquid. Remove the pork from the oven and brush generously with the melted butter, coating all sides. Return the pork to the oven and roast for another 5-10 minutes, basting once more with the remaining butter.

This basting step adds incredible richness and helps maintain moisture. The butter will create a glossy finish and enhance the garlic-herb flavors. Remove the pork when the internal temperature reaches 145°F—this is the perfect medium-pink stage for pork tenderloin.

5

Rest and Garnish for Presentation

Transfer the pork to a cutting board and tent loosely with aluminum foil. Let it rest for 15-20 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful. The temperature will rise to 150°F during resting, which is ideal for serving.

Garnish with the 0.125 cup fresh parsley just before serving. The parsley adds a pop of color and freshness that complements the rich garlic-herb flavors. Slice the pork into 1-inch thick medallions and serve immediately with your favorite sides. Each bite should deliver a perfect balance of tender meat, crispy crust, and aromatic herb flavors.

Pro Tips For Making 8 Lb Pork Tenderloin

  • USE A MEAT THERMOMETER: I learned this the hard way—pork tenderloin can go from perfect to dry in seconds. Aim for 145°F internal temp, and pull it out right when it hits that mark. No guessing, no overcooking.
  • TRIM THE FAT, NOT THE FLAVOR: Pork tenderloin is lean, but those little fat caps? They’re flavor gold. Leave them on for moisture and richness, but if you’re worried about crisping, trim just the outer edges—no need to go full butcher.
  • SALT THE NIGHT BEFORE: Fresh pork soaks up salt like a sponge, and dry-brining overnight (yes, even for 8 lbs) keeps it juicy. Use 1-2 tbsp kosher salt per pound, pat it dry, and let it sit uncovered in the fridge. Trust me, your slices will thank you.
  • SEAR IN BATCHES, OR SUFFER: An 8-lb tenderloin won’t fit in one pan without crowding, and that’s a recipe for steaming, not searing. Work in two batches—hot oil, 3-4 minutes per side—until you’ve got deep brown crusts. Your future guests will notice the difference.

Storing and reheating your leftovers

Refrigerator Storage

After slicing, store your pork tenderloin in an airtight container with a splash of apple cider vinegar (just 1 tbsp) to keep it moist. I use glass Pyrex containers because they maintain flavor better than plastic.

Keep it chilled at 40°F or below for up to 4 days—the crust stays crisp for the first 2 days if sealed properly. 🥗

Freezer Prep Tips

For longer storage, slice the pork into 1-inch medallions and freeze in single-serving portions on a tray before transferring to quart-size freezer bags. This prevents freezer burn and makes reheating easier.

Label bags with the date—it stays safe for 3 months at 0°F. When ready to use, thaw overnight in the fridge. ❄️

Reheating Leftovers

My go-to method is low-and-slow reheating to preserve texture. Place slices in a skillet with 2 tbsp butter and 1 tbsp chicken broth, covering with a lid. Heat on medium-low for 8-10 minutes, basting occasionally.

For microwave reheating, use 50% power for 1-2 minutes, then finish in the oven at 300°F for 5 minutes to crisp the crust. 🔥

Sandwich Revival

Transform leftover slices into pork tenderloin sandwiches with sharp cheddar, honey mustard, and crisp lettuce. Toast the bread lightly to avoid sogginess. I also love adding pickled jalapeños for a tangy kick—this is my favorite way to repurpose leftovers without sacrificing flavor. 🌶️

Fried Rice Upgrade

Use leftover pork in herb fried rice by sautéing with day-old jasmine rice, peas, carrots, and a soy-ginger sauce. The tenderloin adds richness that elevates simple fried rice to restaurant quality.

For extra depth, stir in 1 tsp fish sauce and sesame oil at the end. 💫

Crispy Hash

For a hearty breakfast, dice the pork and pan-fry with potatoes, onions, and smoked paprika until golden. Top with a fried egg and hot sauce for a protein-packed hash. This is my favorite way to use up smaller portions—it’s a game-changer for brunch. 🍳

Frequently asked questions

1

Can I use a smaller pork tenderloin with this recipe?

This method works perfectly for any size tenderloin. For a 4 lb cut, reduce the roasting time by 20-25 minutes total (adjust the 325°F stage to 15-20 minutes instead of 20-25 minutes). The garlic-herb paste and dry brine ratios stay the same—just scale down proportionally. The key is maintaining the 140-145°F internal temperature for that ideal medium-pink center.

2

Why does the recipe call for a dry brine instead of just salting before cooking?

The 24-hour dry brine is a game-changer for large roasts like this. It penetrates deeply to season every inch of meat while helping retain moisture during roasting. Regular salt would only season the surface, risking dryness in the center. The apple cider vinegar in the brine also tenderizes the meat slightly and creates that perfect crust. Think of it as a flavor infusion—no shortcut works as well!

3

What if my oven runs hot or cold? How do I adjust the temperature?

Most home ovens run 25°F hotter or colder than their settings. For this recipe, test your oven first by baking a sheet of cookies at 350°F—if they brown too quickly, your oven runs hot. If so, reduce the roasting temperature by 25°F (use 375°F instead of 400°F for the initial sear). For cold ovens, increase by 25°F. Always use a meat thermometer—it's the only reliable way to gauge doneness regardless of oven accuracy.

4

Can I cook this pork in a smoker instead of the oven?

Yes, but with adjustments! Smoke the tenderloin at 225°F with indirect heat for 2-2.5 hours until it reaches 140°F internally. Use a garlic-herb wood mix (hickory + apple) for 30 minutes at the end to develop the crust. Wrap the pork in butcher paper during the last 30 minutes to speed cooking. The bark will be smokier but less crisp than oven-roasted—great for BBQ lovers!

5

What's the best way to carve thick slices without losing juices?

Always slice against the grain (look for the muscle fibers running lengthwise). Use a sharp chef's knife and cut at a 45-degree angle for thicker portions. For extra juiciness, place the sliced pork on a warm plate and spoon any accumulated pan juices over the top. The slices should be 1-inch thick—this size holds together better than thin cuts. Pro tip: Warm your knife first by running it under hot water for 10 seconds** before slicing.
