Ingredients for 8 lb pork tenderloin
Eight pounds of pork, six simple seasonings, and forty minutes to restaurant-quality perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🐖 | 8 lb | Center-cut, trimmed of silver skin |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 ½ tsp | Coarse grind for texture |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for searing |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High smoke point preferred |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Or 1 tsp dried thyme |
| Garlic Cloves 🧄 | 4 cloves | Smashed, not minced |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, stems removed |
| Honey 🍯 | 2 tbsp | For glaze option |
| Dijon Mustard 🍯 | 1 tbsp | For glaze option |
| Apple Cider Vinegar 🍎 | 1 tbsp | For glaze option |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The pork tenderloin is the star here, and center-cut is non-negotiable—it's more uniform and tender. Grab one from Whole Foods or your butcher's counter if you want the best quality. Look for a piece with good marbling—it's what keeps that juicy pink center. If you're buying online, ButcherBox delivers consistently great cuts. Trim any silver skin before seasoning, but leave the fat cap if it's there—it adds flavor. A digital meat thermometer is your new best friend for this recipe, so invest in a good one if you don't have one already.
No fresh thyme or rosemary? Dried works at one-third the amount, but fresh gives that restaurant-quality aroma. The butter and olive oil combo creates that perfect crust—don't skip the cold cubes. For the glaze, if you're short on time, store-bought honey-mustard sauce works in a pinch (like French's or Annie's). The garlic and rosemary can be swapped for fresh sage if you prefer, but thyme is essential for that classic pork flavor. And trust me on the coarse black pepper—it adds texture that fine ground just can't match.
This pork rests best at room temperature for 30-45 minutes before cooking, so plan ahead. The glaze can be made a day ahead and stored in the fridge. Cooked pork keeps for 3-4 days in the fridge, but it's best served fresh. For leftovers, slice thinly and reheat in a 350°F oven for 10-15 minutes with a splash of broth to keep it moist. Freeze portions for up to 3 months—it reheats beautifully for sandwiches or salads later.

Step-by-step instructions for perfectly juicy pork tenderloin
Here's the foolproof method I use to guarantee tender, juicy pork every time—no guesswork, just reliable results.
Prepare the Pork with Precision
Pat the 8 lb pork tenderloin completely dry with paper towels—this is critical for even cooking and crispy edges. I like to trim any remaining silver skin from the surface with kitchen shears. Place the tenderloin on a wire rack set over a baking sheet to allow air circulation on all sides.
In a small bowl, combine the 2 tbsp kosher salt and 1.5 tsp freshly ground black pepper. Rub this mixture all over the tenderloin, pressing it into the meat so it adheres evenly. Let the seasoned pork sit at room temperature for 30 minutes before cooking—this ensures even cooking from edge to center.
Sear for Maximum Flavor and Texture
Preheat your oven to 425°F. In a large oven-safe skillet, melt the 0.5 cup unsalted butter over medium-high heat until it foams. Add the 0.25 cup extra-virgin olive oil and swirl to coat the bottom of the pan.
Carefully place the pork tenderloin in the skillet, turning to coat all sides with the butter-oil mixture. Sear for 3-4 minutes per side until the exterior develops a deep golden-brown crust. This searing step locks in juices and creates that beautiful caramelized exterior we want.
Roast to Perfect Doneness
Transfer the skillet to the preheated oven and roast for 20-25 minutes for medium-rare (internal temperature 140°F) or 25-30 minutes for medium (145°F). Use a meat thermometer to check the thickest part of the tenderloin—this is the only reliable way to ensure perfect doneness.
Here's the thing—I like my pork tenderloin with a pink center, so I aim for 140-145°F internal temperature. If you prefer fully cooked pork, continue roasting until it reaches 150°F. The roasting time will vary slightly depending on your oven, so watch those temperatures closely.
Create the Honey-Glaze (Optional but Recommended)
While the pork roasts, prepare the glaze by combining the 2 tbsp honey, 1 tbsp Dijon mustard, 1 tbsp apple cider vinegar, 1 tbsp fresh rosemary, 1 tbsp fresh thyme leaves, and 4 smashed garlic cloves in a small bowl. Mix well to create a smooth, flavorful glaze.
Once the pork reaches your desired internal temperature, remove it from the oven and brush all sides with the honey glaze. Return to the oven for 2-3 minutes to caramelize the glaze. This step adds a beautiful sheen and enhances the natural sweetness of the pork.
Rest and Serve with Confidence
Transfer the pork to a cutting board and let it rest for 10-15 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat, ensuring each slice remains moist and flavorful.
Slice the pork tenderloin into ½-inch thick medallions and garnish with the 0.25 cup chopped fresh parsley. The result should be tender, juicy pork with a perfect balance of crispy exterior and succulent interior. Serve immediately with your favorite sides for a complete meal that will impress any crowd.
Pro Tips For Making 8 Lb Pork Tenderloin
- Trim the Fat Patches: Pork tenderloins often have tiny fat caps—leave them. I learned this after trimming one clean and ending up with dry meat; those little patches render into flavor. Just pat them dry first, then season.
- Salt 12 Hours Early: Tenderloin soaks up salt like a sponge. Sprinkle it generously with kosher salt, wrap in plastic, and refrigerate overnight. This guarantees seasoning penetrates evenly—no last-minute guesswork.
- Use a Meat Thermometer: Pork tenderloin hits 145°F fast. If you rely on time alone, you’ll either serve it dry or undercooked. Pull it at 140°F—it’ll carry over to 145°F while resting.
- Brown in Butter, Finish in Oil: Start with 4 tablespoons of cold unsalted butter in a hot pan—it creates a crust. Once seared, add 2 tablespoons of olive oil to baste. The butter adds richness; the oil prevents sticking. (Yes, even if you’re impatient like me.)
Best sauces and condiments for these flavors
Classic Honey-Mustard Glaze
The glaze I use—2 tbsp honey, 1 tbsp Dijon mustard, and 1 tbsp apple cider vinegar—adds a perfect balance of sweet, tangy, and umami flavors that complement the pork's natural richness.
I always include 1 tbsp each of fresh rosemary and thyme plus 4 smashed garlic cloves to infuse the glaze with aromatic depth. This combination works beautifully with the pork's natural sweetness, creating a glossy finish that guests will rave about. 🍯
Herb Butter Sauce
For a richer option, melt ½ cup unsalted butter with 1 tbsp fresh thyme, 1 tbsp fresh rosemary, and 2 minced garlic cloves until fragrant. Strain to remove herb bits, then drizzle over sliced pork.
The butter creates a luxurious coating that melts into the meat, while the herbs echo the seasoning. I often serve this with a sprinkle of crushed black pepper for extra texture. 🧈
Spicy Chipotle Cream Sauce
When I want to add heat, I blend ½ cup sour cream, 1 tbsp chipotle in adobo, 1 tsp lime juice, and ½ tsp cumin until smooth. This sauce pairs perfectly with the pork's tenderness, offering a creamy contrast with a smoky kick.
I serve it alongside the pork and let guests spoon it over their slices. The chipotle adds complexity without overpowering the pork's delicate flavor. 🌶️
Apple Cider Reduction
For a fall-inspired option, simmer 1 cup apple cider with 2 tbsp brown sugar and 1 cinnamon stick until reduced by half. Strain and brush over the pork during the final minutes of roasting.
The caramelized reduction adds a fruity sweetness that cuts through the richness of the meat. I garnish with chopped parsley to brighten the presentation. 🍎
Balsamic Berry Compote
Simmer 1 cup mixed berries (fresh or frozen) with 2 tbsp balsamic vinegar and 1 tbsp honey until thickened. This tangy-sweet compote adds a vibrant contrast to the pork's savory notes.
I serve it as a side sauce or drizzle it over the sliced pork for a pop of color and acidity. The berries provide a refreshing finish that balances the meal. 🍇
Smoky BBQ Sauce
For a Southern-inspired twist, use a store-bought or homemade BBQ sauce with a smoky profile. I recommend brushing it on during the final 5 minutes of roasting to caramelize the sugars.
The smoky depth complements the pork's natural flavors, especially if you've used a dry rub with smoked paprika. This option feels festive and hearty, perfect for gatherings. 🔥

Frequently asked questions
Can I cook an 8 lb pork tenderloin without a meat thermometer?
While I always recommend using a meat thermometer for perfect results, you can estimate timing by visual cues. For medium-rare (140°F), look for a pink center with juices running slightly pink. For medium (145°F), the juices should be clear. The crust should be deep golden-brown. Remember, pork tenderloin cooks faster than other cuts, so start checking after 20 minutes at 425°F.
How do I prevent the pork from drying out when cooking?
Three key steps:
- Pat the pork completely dry before seasoning,
- Use a wire rack to allow air circulation, and
- Never skip the 10-15 minute rest after cooking. The dry brine method in this recipe locks in moisture, but the resting period is absolutely crucial. Slice against the grain if you're concerned about tenderness, though pork tenderloin is naturally tender.
What's the best way to reheat leftover pork tenderloin?
Slice thinly and reheat in a 350°F oven for 10-15 minutes with a splash of chicken broth to maintain moisture. For quick reheating, use the microwave on 50% power for 1-2 minutes per slice. Never reheat in the skillet—it will dry out. Leftover pork works beautifully in sandwiches or salads too!
Can I substitute butter with oil for cooking?
You can use 100% oil (like avocado or grapeseed), but you'll lose the rich flavor and crispy crust butter provides. If substituting, use ¼ cup more oil than the butter called for. For best results, I recommend sticking with the butter-oil combination—it creates that perfect balance of flavor and texture.
How do I adjust this recipe for a smaller or larger pork tenderloin?
Pork tenderloin cooks at about 15 minutes per pound for medium-rare (140°F) at 425°F. For a 4 lb tenderloin, reduce cooking time to 10-12 minutes after searing. For larger cuts (up to 12 lbs), increase time by 5-7 minutes per pound. Always use a meat thermometer—size affects cooking time more than you'd expect!
