How to cook Smithfield pork tenderloin in the oven
Prepare the Smithfield pork tenderloin:
1. Remove the pork from the refrigerator about 15 minutes before roasting to bring it to room temperature.
2. Position a rack in the middle of the oven and preheat the oven to 400° F (about 200º C).
3. Trim away and discard the silver skin from the tenderloins. Use a paring knife, and firmly score crisscross lines that are about ⅛-inch deep and ¼-inch apart on the "flat" side of each tenderloin. Do not skip this step; otherwise, your tenderloins won’t bond together and can fall apart when you slice after roasting and resting. Make sure to pat dry each tenderloin with a paper tower!!!
4. Then place the flat sides together head-to-tail (thick end to thin end) so the overall circumference is more even and the tenderloins cook more evenly. Tie with butcher's string (not too tightly), spacing the ties 1 ½ inches apart. See Instructions on the NOTES!!!
5. In a blender or food processor, blend or process together the oil, garlic, bouillon, salt, pepper, paprika, and rosemary.
6. Place pork tenderloin, fat side up, on a rack set over a roasting pan. Spread garlic paste all over the tenderloin loin.
7. Roast in the oven until a meat thermometer inserted into the thickest part of the tenderloin registers 145°F, about 20-30 minutes, depending on the thickness of the tenderloin.
8. Remove from the oven, transfer the pork to a platter, cut the strings, and discard. Keep it warm, tented with foil, while making the wine sauce.
9. Slice the roasted pork tenderloin after resting for 5-10 minutes or just before serving.
For the wine sauce:
Pour the white wine into the roasting pan (rack removed) in which the tenderloin was cooked. Place pan over medium heat, and scrape up browned bits from its bottom.
- Add stock, salt, and pepper; then, bring to a simmer. Cook, stirring, until the liquid has reduced to half. Skim fat from the surface of the liquid.
- Strain the sauce and place it into a clean saucepan. Whisk in the cornstarch mixture and cook over medium heat until the sauce has thickened.
4. Serve it hot in a side bowl with the sliced Smithfield pork tenderloin. Garnish the loin with some chopped rosemary on the top, and also with some rosemary sprigs and sliced lemon on the side. Steamed asparagus makes a great light side for this roasted tenderloin!
A step-by-step guide to tying a 2-piece pork tenderloin:
Place the 2 pork tenderloins together on a cutting board with their fatty side facing outward.
Loop one end of the kitchen twine around the roast about 1 inch from the side and tie it in a simple knot. The size of the twine will depend on the thickness of the tenderloins and also how you twine your tenderloins.
Place the remaining string over about 1 ½ inches; hold it into place with one hand while putting it under and around the roast in a parallel loop using the other hand. When the loop is complete, thread the string through the loop and pull over another 1 ½ inches. (There will be 2 loops around the roast with a perpendicular line connecting them).
- Flip over the roast and run the string around the back side, winding around each original loop and pulling tight.
- Return the roast to its original position and tie off at the first knot. Cut off excess string.
- Alternatively, you can twine each part of the loin individually, keeping a 1 to 1 ½ inch space between them! Leave 1 inch free at each end of the tenderloins.
How long to cook pork tenderloin in oven
The cooking time varies depending on the oven temperature, the thickness of the tenderloin, the weight, and whether it was seared before roasting. Generally, it takes about 20-30 minutes at 400°F. This is all the more reason to use a meat thermometer to ensure perfect doneness (145° F).
Useful tips for making roasted pork tenderloin
Room temperature: Bring the pork tenderloin to room temperature before roasting it for a more even cook.
- Trim first: Trim away the silver skin for the most tender result.
- Score the pork: Don’t forget to score the tenderloins to help them bind together and prevent them from falling apart once they’re sliced.
- Use a tie: Tie the tenderloins together with the butcher's string to ensure they cook evenly.
Thermometer: Use a meat thermometer to check for the correct internal temperature. For pork, it should reach an internal temperature of 145°F.
Rest: Allow the pork tenderloin to rest for at least 5-10 minutes before slicing it so the juices have time to redistribute.
Deglaze: Deglazing the roasting pan with white wine creates a much more flavorful and complex base for the sauce.
- Strain: Strain the sauce and thicken it with a cornstarch slurry for a smooth texture.
- Garnish: For an aromatic and elegant presentation, don’t forget to garnish your baked pork tenderloin with fresh rosemary sprigs and slices of lemon.
What to serve with baked pork tenderloin
Once your Smithfield pork tenderloin has rested, serve it with some side dishes like these:
Garlic mashed potatoes
- Roasted carrots and parsnips
FAQ's
What are the differences between Smithfield pork loin vs. pork tenderloin?
Despite their close names, pork loin and pork tenderloin are two different cuts of meat that come from separate parts of the pig. The pork loin comes from the back of the pig, specifically the area between the shoulder and the start of the leg. Tenderloin is a small, elongated cut that’s found under the backbone and runs alongside the ribs. Pork tenderloin is more tender than pork loin (hence the name), which makes it more delicate and succulent. The loin is dense and firm in comparison. For these reasons, pork tenderloin is often more expensive than loin, on a per-pound basis.
What is the best way to cook Smithfield pork tenderloin?
It’s best to roast Smithfield pork tenderloin in the oven for a few reasons:
Even cooking: Cooking oven-baked tenderloin at a high temperature ensures even heat distribution so the meat roasts uniformly.
Flavor development: As the tenderloin roasts, the surface caramelizes and envelopes a rich brown crust, adding to its flavor.
Moisture retention: Since tenderloin is a leaner cut of meat, it can dry out easily if it’s overcooked. High heat for a shorter period helps lock in the meat's juices, getting a moist and tender result.
What is the proper internal temperature for pork tenderloin?
According to the USDA, The internal temperature for roasted pork tenderloin is 145°F for medium doneness, measured with a meat thermometer. To use a meat thermometer properly, insert the probe into the thickest part of the tenderloin, ensuring it’s inserted lengthwise. Start checking around 5-10 minutes before the cooking time of this recipe. Once it reaches 145°F, remove it from the oven and let it rest for 5-10 minutes, tented with foil.
Is it better to cook pork tenderloin at 350°F or 400°F?
Cooking at 400°F allows the baked pork tenderloin to develop a nice crust on the outside while still remaining tender on the inside, yielding more flavor. However, you can cook it at 350°F, which may result in a more even cook, but you won’t achieve the same crust. Ultimately, it’s personal preference, but pork tenderloin is typically cooked at 400°F.
Should roasted pork tenderloin be cooked fast or slow?
Roasted pork tenderloin is best cooked at a higher temperature for a shorter period, letting the outside to brown while the inside remains tender and juicy. This is why 400°F is the most common temperature to cook pork tenderloin at.
Is it better to sear pork tenderloin before baking?
Searing the pork tenderloin before baking can help develop a tasty crust, but it is not necessary for this recipe.
Storage
If you have leftover garlic pork tenderloin, follow these storage and reheating tips:
Fridge: Once fully cooled, store the leftover pork tenderloin in an airtight container for up to 3-4 days in the fridge.
- Freezer: You can freeze cooked and cooled pork tenderloin in a freezer-safe container for up to 3 months.
- Reheating: To reheat, place the tenderloin in the oven at 325°F until warmed through. Be careful not to overcook it as it will dry out the meat.
Variations
Tangy: Add Dijon mustard to the garlic-herb paste for a tangy twist.
- Herbs: Substitute fresh thyme or sage for the rosemary.
- Glaze: Drizzle a balsamic glaze on the finished dish for added sweetness and depth.
- Spice rub: Use a dry rub with spices like chili powder, cumin, and paprika.
- Bacon wrapped: Wrap the pork tenderloin in bacon before roasting it for added flavor and moisture.

I made this pork tenderloin for a Sunday supper recently and tasted so good I will be making it again, this time for Mother’s Day. Thanks for the recipe!
Jill says
I love pork loin...this looks so good! Do I need a special kind of pan to cook it in, or can I just use a pyrex?
Denise Browning says
Jill, thanks for your comment! I do appreciate...
You can use a pyrex. Just make sure that it's made of tempered glass (it means that can go to the oven without shattering). But you have to know that it will take longer to cook. I advice you to lay down aluminum foil on the bottom of the pyrex for easier cleanup (no stuck on grease that is hard to clean off). I roasted mine in an aluminum baking pan. Anyway, as soon as it reaches 155 F, please remove the loin from oven.
