This oven roasted pork tenderloin is the weeknight dinner hero you didn’t know you needed. With a simple garlic-herb rub and a hot oven, you get a beautifully browned crust and a juicy, tender center every time. It’s a foolproof method that works for a casual family meal or a special occasion, and it comes together in under 30 minutes of active time.
Ingredients
- 1 pork tenderloin (about 1 lb / 450 g), silver skin removed
- 2 tablespoons (30 ml) olive oil
- 1 tablespoon (8 g) minced garlic (about 3 cloves)
- 1 teaspoon (2 g) dried rosemary
- 1 teaspoon (2 g) dried thyme
- 1 teaspoon (5 g) salt
- 1/2 teaspoon (1 g) black pepper
- 1 tablespoon (15 ml) Dijon mustard (optional, for extra tang)
Instructions
- Preheat your oven to 425°F (220°C). Line a rimmed baking sheet with aluminum foil or parchment paper for easy cleanup.
- Pat the pork tenderloin dry with paper towels. This helps the seasoning stick and promotes browning.
- In a small bowl, mix together the olive oil, minced garlic, rosemary, thyme, salt, and pepper. If using Dijon mustard, stir it in as well.
- Rub the mixture all over the pork tenderloin, coating it evenly.
- Place the tenderloin on the prepared baking sheet. Insert an oven-safe meat thermometer into the thickest part of the meat, if you have one.
- Roast for 20-25 minutes, or until the internal temperature reaches 145°F (63°C) – the USDA FSIS safe minimum for whole cuts of pork. The temperature will rise about 5°F during resting.
- Remove from the oven and let rest on the baking sheet for 5-10 minutes. This allows the juices to redistribute, ensuring a moist result.
- Slice into 1/2-inch thick medallions and serve warm.
Tips
- Don’t skip the rest: Resting is not optional – it’s what keeps the pork juicy. If you cut it immediately, the juices will run out onto the cutting board.
- Use a thermometer: Pork tenderloin is lean and can go from perfect to dry in a minute. An instant-read thermometer is your best friend. Insert it sideways into the thickest part.
- Trimming the silver skin: The silvery-white membrane on the outside of the tenderloin becomes chewy when cooked. Ask your butcher to remove it, or slide a sharp knife under it and slice it off.
- Make it ahead: You can rub the seasoning on the pork up to 24 hours in advance. Keep it covered in the fridge, then bring to room temperature for 30 minutes before roasting.
Serving Suggestions
This pork tenderloin pairs beautifully with roasted potatoes, a simple green salad, or buttery green beans. For a heartier meal, serve it over creamy polenta or with a side of garlic mashed potatoes. A spoonful of apple sauce or a drizzle of balsamic glaze adds a nice sweet-tart contrast.
Variations
- Spicy rub: Add 1 teaspoon of smoked paprika and 1/4 teaspoon of cayenne pepper to the rub for a smoky, spicy kick.
- Maple-Dijon glaze: After roasting for 15 minutes, brush the tenderloin with a mixture of 2 tablespoons maple syrup and 1 tablespoon Dijon mustard. Continue roasting for the last 5-10 minutes.
- Herb crust: Instead of dried herbs, use 2 tablespoons of fresh chopped rosemary, thyme, and parsley. Mix with 1/4 cup (25 g) grated Parmesan cheese and press onto the pork before roasting.
- Pan sauce: After removing the pork, place the baking sheet over medium heat (if oven-safe) or transfer drippings to a skillet. Add 1/2 cup (120 ml) chicken broth and 1/4 cup (60 ml) white wine, simmer for 2-3 minutes, and whisk in 1 tablespoon butter for a quick sauce.
Storage and Reheating
Refrigerate any leftovers in an airtight container within 2 hours of cooking. They will keep for 3-4 days. To reheat, slice the pork and warm it gently in a skillet with a splash of broth or water over medium-low heat, or microwave in 30-second intervals. Avoid overcooking, as it will dry out. You can also freeze cooked pork tenderloin for up to 3 months; thaw overnight in the fridge before reheating.
Frequently Asked Questions
How do I know when pork tenderloin is done without a thermometer? While a thermometer is strongly recommended, you can check by making a small cut in the thickest part. The meat should be slightly pink in the center (for medium) or no longer pink (for well-done). However, this method is less reliable and can easily lead to overcooking. The USDA FSIS safe minimum is 145°F (63°C) with a 3-minute rest, and a thermometer is the only way to be sure.
Should I sear the pork before roasting? Searing in a hot skillet for 2-3 minutes per side before roasting adds extra flavor and color, but it’s not necessary. This recipe uses a high oven temperature to achieve a browned crust. If you do sear, reduce the roasting time by about 5 minutes.
Can I use pork loin instead of tenderloin? Yes, but they are different cuts. Pork loin is larger and leaner, and will take longer to cook (about 30-40 minutes at 425°F/220°C). Adjust your cooking time and use a thermometer to check for doneness.
Why is my pork tenderloin tough? Toughness usually comes from overcooking. Since tenderloin is so lean, it dries out quickly. Always cook to 145°F (63°C) and rest. Also, make sure to remove the silver skin, which can be chewy.
Can I marinate the pork overnight? Yes, you can marinate it in the rub for up to 24 hours in the fridge. This will deepen the flavor. Just be sure to bring it to room temperature for 30 minutes before roasting so it cooks evenly.
What if I don’t have Dijon mustard? You can omit it, or use yellow mustard or a spoonful of whole-grain mustard. It adds a subtle tanginess that complements the pork, but the recipe works fine without it.
