How Long to Cook Pork Tenderloin in Oven at 425?
Pork tenderloin cooked in a 425°F oven typically requires between 20 and 25 minutes, depending on the size of the tenderloin and desired internal temperature. It’s crucial to use a meat thermometer to ensure the internal temperature reaches 145°F for safe and delicious results.
Understanding Pork Tenderloin
Pork tenderloin is a lean, boneless cut of meat from the pork loin. It’s known for its tenderness and mild flavor, making it a versatile option for various cooking methods. Unlike the pork loin roast, which is a larger, fattier cut, the tenderloin is best cooked quickly at higher temperatures to prevent it from drying out.
Benefits of Cooking at 425°F
Cooking pork tenderloin at 425°F offers several advantages:
- Quick cooking time: High heat allows the tenderloin to cook relatively quickly, making it ideal for busy weeknights.
- Even browning: The high temperature promotes a beautiful, even browning on the outside, enhancing the flavor and presentation.
- Moist interior: When cooked properly, the high heat sears the outside, helping to lock in moisture and keep the inside tender and juicy.
- Flavor enhancement: High heat caramelizes the natural sugars in the pork, intensifying its flavor and creating a delicious crust.
The Step-by-Step Cooking Process
Here’s a detailed guide to cooking pork tenderloin in the oven at 425°F:
- Preheat the oven: Preheat your oven to 425°F (220°C).
- Prepare the tenderloin: Remove the silver skin (a thin membrane) from the tenderloin. This helps prevent it from curling and becoming tough. Pat the tenderloin dry with paper towels.
- Season the tenderloin: Season generously with salt, pepper, and any other desired spices or herbs. Consider using a dry rub or marinade for added flavor.
- Sear (optional): While optional, searing the tenderloin in a hot skillet before baking can enhance browning and flavor. Sear on all sides for 2-3 minutes per side.
- Bake the tenderloin: Place the tenderloin on a baking sheet or in a roasting pan. Bake for 20-25 minutes, or until a meat thermometer inserted into the thickest part of the tenderloin registers 145°F (63°C).
- Rest the tenderloin: Remove the tenderloin from the oven and let it rest for 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
- Slice and serve: Slice the tenderloin into medallions and serve with your favorite sides.
Common Mistakes to Avoid
- Overcooking: Overcooking is the biggest mistake when cooking pork tenderloin. It can quickly become dry and tough. Use a meat thermometer to ensure accurate cooking.
- Skipping the rest: Resting the meat after cooking is essential for moisture retention. Don’t skip this step!
- Not removing the silver skin: The silver skin can become tough and chewy during cooking. Remove it before seasoning.
- Uneven seasoning: Ensure the tenderloin is evenly seasoned for optimal flavor.
- Opening the oven door frequently: Avoid opening the oven door during cooking, as this can lower the temperature and increase cooking time.

Frequently Asked Questions
Can I cook pork tenderloin at a lower temperature?
Yes, you can cook pork tenderloin at a lower temperature, such as 350°F (175°C). However, it will take longer to cook and may not brown as evenly. You’ll need to adjust the cooking time accordingly, and always use a meat thermometer to ensure the internal temperature reaches 145°F.
What is the safe internal temperature for pork tenderloin?
The safe internal temperature for cooked pork tenderloin is 145°F (63°C), as recommended by the USDA. This temperature ensures that any harmful bacteria are eliminated while maintaining a tender and juicy texture.
How do I know when the pork tenderloin is done?
The best way to determine if the pork tenderloin is done is to use a meat thermometer. Insert the thermometer into the thickest part of the tenderloin, avoiding bone if present. When the thermometer registers 145°F (63°C), the pork is cooked to the proper doneness.
Can I use a marinade on pork tenderloin?
Absolutely! Marinating pork tenderloin is a great way to add flavor and moisture. Marinate the tenderloin for at least 30 minutes, or up to overnight, in the refrigerator. Discard the marinade after use.
What if my pork tenderloin is still pink inside?
A slight pinkness in the center of the pork tenderloin is perfectly acceptable and indicates that it is cooked to a safe and juicy medium doneness. As long as the internal temperature has reached 145°F (63°C), it is safe to eat.
Why is my pork tenderloin dry?
Dry pork tenderloin is usually the result of overcooking. Always use a meat thermometer to ensure accurate doneness. Resting the meat after cooking also helps to retain moisture.
Can I freeze pork tenderloin?
Yes, you can freeze both raw and cooked pork tenderloin. Wrap it tightly in plastic wrap and then in freezer-safe bags or containers. Frozen raw pork tenderloin can be stored for several months, while cooked pork tenderloin can be stored for 2-3 months.
Should I sear the pork tenderloin before baking?
Searing the pork tenderloin before baking is optional but recommended. Searing helps to develop a rich, flavorful crust and enhance the overall presentation. Sear the tenderloin on all sides in a hot skillet before transferring it to the oven.
What are some good side dishes to serve with pork tenderloin?
Pork tenderloin pairs well with a variety of side dishes, including roasted vegetables, mashed potatoes, rice, quinoa, salads, and fruit sauces. Complementary flavors include apples, cranberries, and herbs like rosemary and thyme.
Can I use this method for other cuts of pork?
While the 425°F oven temperature can be used for other cuts, the cooking time will need to be adjusted significantly. Pork loin roast, for example, requires a longer cooking time due to its larger size. Always use a meat thermometer for accurate doneness.
How long should I let the pork tenderloin rest after cooking?
It’s recommended to let the pork tenderloin rest for 5-10 minutes after cooking. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product. Tent the tenderloin loosely with foil while resting.
Is it necessary to remove the silver skin from the pork tenderloin?
Yes, it’s highly recommended to remove the silver skin from the pork tenderloin. The silver skin is a thin membrane that can become tough and chewy during cooking. Removing it will improve the texture of the cooked tenderloin.
