The marinating process involves soaking the pork tenderloin in a mixture of seasonings and liquid for several hours or overnight.

You could make a classic spinach and cheese stuffing, or get creative with combinations like apple and fennel or mushroom and prosciutto. Remember to secure the stuffed tenderloin with kitchen twine before searing and roasting to keep everything intact.

Glazing: Adding a glaze towards the end of the roasting time can provide a delectably sweet, savory, or tangy crust to your pork tenderloin. A simple glaze can be made using ingredients like brown sugar, honey, mustard, or fruit preserves. The glaze caramelizes beautifully when the tenderloin is cooked in the oven at 400, adding a delightful finishing touch.

Pairing baked pork tenderloin with Sauces: Finally, serving your pork tenderloin with a complementary sauce can add another layer of complexity and enjoyment to your dish. This could be a simple gravy made from the pan drippings, a fruit-based sauce like apple or cranberry for a sweet contrast, or a wine reduction for a touch of elegance.

Alternatives to Cooking Pork Tenderloin in the Oven at 400

Let’s look at some alternative cooking methods that can bring out different flavors and textures in your pork tenderloin, offering you a varied culinary experience.

Slow Cooking: If you prefer a “set it and forget it” approach, consider using a slow cooker. While this method takes longer than cooking pork tenderloin in the oven at 400, it results in a melt-in-your-mouth texture that’s worth the wait. Season your pork tenderloin as desired, then place it in the slow cooker with some broth or other cooking liquid. Cook on low for 6-8 hours or until the tenderloin is tender and cooked through. This method works especially well for recipes that include a sauce or gravy.

Sous Vide: The sous vide method involves sealing the pork tenderloin in a plastic bag and cooking it in a water bath at a precise temperature. This method ensures that the tender pork tenderloin is cooked perfectly evenly and retains maximum juiciness. After the sous vide process, you’ll want to quickly sear the tenderloin in a hot pan to give it a flavorful crust.

Pan Roasting: Another method is pan roasting, which is somewhat similar to cooking pork tenderloin in the oven at 400 but involves only one cooking vessel. First, sear the tenderloin in a hot skillet on all sides. Then, instead of transferring it to the oven, simply reduce the heat, cover the skillet, and let it continue to cook until it reaches the desired internal temperature.
