Pork tenderloin is a tender, lean cut of meat that, when prepared correctly, can be a delicious and satisfying dish. One of the most popular methods of cooking pork tenderloin is in the oven, and a common temperature for this process is 400°F. In this article, we’ll explore the steps to achieve a perfectly cooked pork tenderloin in the oven at 400°F, including the recommended cooking time, preparation, and some mouthwatering recipe ideas.

Why 400°F?

Cooking pork tenderloin in the oven at 400°F is a reliable method because it strikes a balance between cooking the meat thoroughly and creating a flavorful, caramelized crust on the outside. This temperature allows the meat to reach a safe internal temperature while keeping it juicy and tender. However, achieving this perfection requires proper preparation and timing.

How Long to Cook Pork Tenderloin at 400°F

The cooking time for pork tenderloin in the oven at 400°F can vary depending on the size of the tenderloin and your desired level of doneness. As a general guideline, here’s an approximate cooking time for pork tenderloin at this temperature:

Small Pork Tenderloin (1 lb): 20-25 minutes

Medium Pork Tenderloin (1.5 lbs): 25-30 minutes

Large Pork Tenderloin (2 lbs): 30-35 minutes

Keep in mind that these times are estimates, and the most reliable method for determining doneness is by using a meat thermometer. The pork tenderloin is safe to eat when it reaches an internal temperature of 145°F (63°C). This is considered medium-rare, which is suitable for pork tenderloin, as the meat will continue to cook as it rests. If you prefer a more well-done pork tenderloin, cook it until it reaches an internal temperature of 160°F (71°C). However, be cautious not to overcook it, as pork tenderloin can become dry and less flavorful when overdone.

Preparing the Pork Tenderloin

To ensure a delectable outcome, proper preparation is key:

Seasoning: Before cooking, season the pork tenderloin generously with your preferred blend of herbs, spices, and salt. Popular seasonings include garlic, rosemary, thyme, paprika, and black pepper. For a simple yet delicious option, try marinating the pork in olive oil, garlic, and fresh herbs for a few hours or overnight.

Searing (Optional): While searing is not a mandatory step, it can enhance the flavor and texture of the pork. Heat a skillet over medium-high heat with a small amount of oil, then sear the pork tenderloin for a couple of minutes on each side until it develops a golden crust. This adds an extra layer of flavor.

Resting: Allow the pork tenderloin to rest for about 5-10 minutes after cooking. This step is crucial as it lets the juices redistribute within the meat, resulting in a more succulent and tender final product.
