Ingredients for 3 pound pork tenderloin
Restaurant-quality pork tenderloin starts with these precise ingredients and professional techniques.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 3 lb | Center-cut, trimmed of silver skin |
| Kosher Salt 🧂 | 1 ½ cups | Diamond Crystal preferred for precise measurement |
| Granulated Sugar 🍚 | ½ cup | White or brown sugar |
| Black Peppercorns 🌶️ | 1 tbsp | Freshly cracked for optimal flavor |
| Garlic Cloves 🧄 | 8 cloves | Smashed but not minced |
| Fresh Thyme Sprigs 🌿 | 4 whole | Stems removed, leaves packed |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for searing |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High smoke point preferred |
| Fresh Rosemary 🌿 | ¼ cup | Needles finely chopped |
| Apple Cider Vinegar 🍎 | ¼ cup | For balanced brine acidity |
| Water 💧 | 4 cups | Filtered preferred for clarity |
| Yellow Onion 🧅 | 1 whole | Quartered for roasting |
| Carrots 🥕 | 4 whole | Baby carrots or whole carrots halved |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
The pork tenderloin's quality makes all the difference—look for a center-cut with even thickness and minimal connective tissue. Whole Foods or your local butcher shop typically carry the best cuts; avoid pre-trimmed tenderloins as they often lose moisture during processing. The Diamond Crystal kosher salt is essential here—it dissolves more completely than table salt, ensuring even brine penetration. For the fresh herbs, focus on vibrant green leaves; wilted thyme or rosemary will compromise flavor. Prep your tenderloin by trimming any silver skin and patting it dry with paper towels before brining—this step is non-negotiable for crispy edges.
No fresh rosemary? Dried rosemary at one-third the amount works in a pinch, though fresh delivers superior aroma. Substituting apple cider vinegar? White vinegar or lemon juice maintains acidity, but the fruity notes of apple cider enhance the pork's natural sweetness. The garlic can be roasted ahead of time for deeper flavor—simply toss the smashed cloves with olive oil and roast at 400°F for 10 minutes before using. For the butter, European-style unsalted butter like Plugrá has higher fat content, which improves searing performance. If you're short on time, the brine can be reduced to 12 hours, though 24 hours yields the most tender results.
The brine mixture should be stored in a non-reactive container like glass or food-grade plastic, covered and refrigerated. Use within 3 days for optimal freshness. The roasted vegetables keep well in the fridge for 5 days—store them separately from the pork to maintain texture. For make-ahead convenience, fully cook the pork tenderloin, let it cool, then refrigerate wrapped in foil. Reheat gently in a 300°F oven for 15-20 minutes until internal temperature reaches 145°F, ensuring it reheats evenly without drying out.

Step-by-step instructions for one-pan roasted pork tenderloin
Transform a simple pork tenderloin into a showstopping centerpiece with perfectly crisp edges and succulent interior.
Prepare the Dry Brine for Maximum Flavor
In a large bowl, combine the 3 lb pork tenderloin, 1.5 cups kosher salt, 0.5 cup granulated sugar, and 1 tablespoon freshly cracked black peppercorns. Using your hands, work the mixture into the meat until fully coated and the salt penetrates all surfaces. This dry brine creates an impermeable crust that locks in juices while developing an irresistible bark.
Place the seasoned pork on a wire rack set over a baking sheet and refrigerate uncovered for 12-24 hours. The extended brining time is critical—it ensures even seasoning and allows the salt to break down muscle fibers for unparalleled tenderness. Real talk: Skipping this step results in dry, flavorless pork.
Create the Herb-Infused Roasting Pan
In a separate bowl, mix the 2 tablespoons extra-virgin olive oil, 0.25 cup finely chopped fresh rosemary, 0.25 cup apple cider vinegar, and 8 smashed garlic cloves. Transfer this mixture to a large roasting pan and spread it evenly across the bottom. The acidity in the vinegar prevents the vegetables from drying out while adding brightness to the pork.
Add the quartered yellow onion and halved carrots to the pan, arranging them in a single layer. The vegetables will roast alongside the pork, creating a complete one-pan meal. Preheat your oven to 425°F while you prepare the pork for roasting—this high temperature is essential for achieving those crispy edges we're after.
Sear the Pork for Crispy Perfection
Remove the brined pork from the refrigerator and let it sit at room temperature for 30 minutes. This step ensures even cooking. Using a paper towel, pat the pork dry completely—moisture is the enemy of crispy skin. Heat an oven-safe skillet over medium-high heat and add the 0.5 cup cold cubed butter. When the butter foams, carefully place the pork in the skillet.
Sear the pork for 4-5 minutes per side until the exterior develops a deep golden-brown crust. The butter will render and create a flavorful fond that caramelizes beautifully. Here's the thing—don't move the pork during searing. You want that crust to form undisturbed. Once browned, transfer the pork to the prepared roasting pan with the vegetables.
Roast to Tender Perfection
Transfer the roasting pan to the preheated 425°F oven and roast for 25-30 minutes until the internal temperature reaches 145°F when measured with a meat thermometer. The pork should be slightly pink in the center—it will continue cooking as it rests. The vegetables should be tender and caramelized, absorbing the herb-infused juices from the pan.
For the final 5 minutes of cooking, increase the oven temperature to 450°F to intensify the browning of the pork's surface. This broiling step creates that coveted crispy exterior while keeping the interior juicy. Watch carefully—you want the edges to be deeply browned but not burned. If the vegetables begin to char too quickly, tent them loosely with foil.
Rest and Serve with Herb Garnish
Remove the pork from the oven and transfer it to a cutting board. Tent loosely with foil and let it rest for 15-20 minutes before slicing. This resting period is non-negotiable—it allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful. During this time, skim any excess fat from the roasting pan and spoon the herb-infused juices over the sliced pork.
Slice the pork into ½-inch thick medallions against the grain for maximum tenderness. Garnish each serving with the 0.25 cup chopped fresh parsley and serve immediately with the roasted vegetables. The result should be pork with a perfectly crisp exterior, a pink center that's tender but not dry, and vegetables infused with the aromatic herb mixture from the pan.
Pro Tips For Making 3 Pound Pork Tenderloin
- USE A MEAT THERMOMETER: I learned this the hard way—pork tenderloin looks done when it’s still overcooked. Aim for 145°F internal temp (not 160°F, which is for whole cuts). The USDA changed the guidelines, and your meat will be juicier if you trust the thermometer over guesswork.
- DRY THE PORK WELL: Pat that tenderloin thoroughly with paper towels before seasoning. I used to skip this, and my crust never formed right—now I make sure it’s bone-dry, especially if it’s fresh from the fridge. Wet skin = steam, not sear.
- SALT IN TWO STAGES: Don’t just salt once—do a light dry rub 30 minutes before cooking, then a heavier coat right before hitting the pan. The first layer helps tenderize, while the second ensures flavor sticks. (Yes, even if you’re impatient like me, give it that time.)
- SMASH THE GARLIC: Minced garlic burns. Instead, peel and smash whole cloves with the flat side of your knife—just enough to bruise them. Toss them in the pan with the pork after searing, and they’ll infuse flavor without turning bitter. (Your future self will thank you.)
Best sauces and condiments for this recipe
Classic Apple Cider Glaze
This tangy-sweet glaze takes your pork to the next level. Simmer ½ cup apple cider vinegar, ¼ cup honey, and 1 tbsp Dijon mustard in a saucepan until reduced by half. Brush generously over the pork during the final 10 minutes of roasting for a sticky, caramelized finish.
The acidity cuts through the richness while the honey adds depth. I love using local Georgia apple cider from my favorite farm stand—it makes all the difference. 🍎
Brown Sugar-Bourbon Sauce
For a Southern-inspired twist, combine ¼ cup brown sugar, 2 tbsp bourbon (I use Buffalo Trace), 1 tbsp apple cider vinegar, and 1 tsp smoked paprika in a small saucepan.
Simmer until thickened, then drizzle over sliced pork. The bourbon adds warmth while the brown sugar creates a beautiful crust. This sauce pairs perfectly with the herb-roasted vegetables from your pan. 🥃
Creamy Dill Sauce
Blend ½ cup sour cream, 2 tbsp mayonnaise, 1 tbsp fresh dill, 1 tsp lemon juice, and ½ tsp garlic powder for a refreshing contrast. Spoon over sliced pork or serve on the side for dipping.
The cool, herby notes balance the richness beautifully. I keep this sauce chilled until serving to maintain its texture. 🌿
Honey-Mustard Pan Sauce
Use the rendered juices from your roasting pan to create this effortless sauce. After removing the pork, skim off excess fat, then whisk in 2 tbsp Dijon mustard, 1 tbsp honey, and 1 tsp apple cider vinegar.
Simmer for 3-4 minutes until slightly thickened. The mustard adds depth while the honey keeps it balanced. This sauce works wonders with the crispy edges of your pork tenderloin. ✨
Spicy Chipotle Cream
For heat lovers, mix ½ cup sour cream, 1 tbsp chipotle in adobo, ½ tsp cumin, and 1 tsp lime juice. The smoky chipotle adds complexity while the cream keeps it rich.
Drizzle over sliced pork or serve as a dipping sauce. This sauce became a crowd-pleaser at The Smoky Pig—guests always ask for seconds. 🌶️
Rosemary-Infused Pan Jus
Reduce the roasting pan juices by ⅔** after removing the pork, then whisk in 1 tbsp cold butter for a silky finish. The rosemary from your pan infusion adds aromatic depth.
This jus is perfect for spooning over the pork or drizzling over roasted vegetables. It's the ultimate one-pan solution that requires zero extra effort. 💫

Frequently asked questions
Why is the 24-hour dry brine so important for a 3-pound pork tenderloin?
The extended dry brine is the secret weapon for restaurant-quality results. The salt and sugar penetrate deeply, breaking down muscle fibers for unparalleled tenderness while creating that coveted crispy bark. For a 3-pound cut, the longer brining time ensures even seasoning throughout the thicker center. Think of it as a flavor and moisture insurance policy—especially important for larger tenderloins that can dry out if not properly prepped.
Can I substitute the dry brine for a wet brine or marinade?
You can try a wet brine (1 cup salt + 4 cups water per pound), but the dry brine delivers superior texture and crust. For a marinade, use a mix of olive oil, garlic, herbs, and a splash of vinegar—just remember marinating for more than 4 hours can make the meat mushy. The dry brine's sugar component also helps create that perfect caramelized exterior during searing.
What's the best way to check doneness without overcooking?
Always use a meat thermometer—insert it into the thickest part of the tenderloin. Remove from oven when it hits 145°F (the USDA safe minimum). The pork will continue cooking as it rests, reaching 150°F while juices redistribute. Never rely on time alone—pork thickness and oven variations affect cooking time. A properly brined tenderloin should be slightly pink in the center even at 145°F.
How do I adjust this recipe for a smaller tenderloin?
For a 1.5-pound tenderloin, reduce all brine ingredients by 50% and halve the roasting time to 15-20 minutes at 425°F. Keep the same internal temperature target of 145°F. The key is maintaining the same thickness-to-weight ratio—thinner cuts cook faster. The searing time remains the same (4-5 minutes per side) to develop the crust. Smaller tenderloins benefit from slightly lower oven temps (400°F) to prevent overcooking.
Why did my pork turn out dry even after brining?
Most likely, you skipped the resting period or overcooked it. The 15-20 minute rest is non-negotiable—it lets juices redistribute. Also check: Did you pat the pork dry before searing? Moisture prevents proper browning. Another culprit? Cooking past 145°F—pork continues cooking after removal from heat. For extra insurance, brine for 24 hours and use a meat thermometer. Dry pork often means the cut was too lean or overworked during prep.
