Pork Tenderloin Wrapped in Foil in Oven

Pork tenderloin can dry out quickly. Fully wrapping the meat in a piece of foil can lock in its flavor and retain its moisture.

It also prevents the meat from sticking to the oven tray.

Though aluminum foil is the ideal material used, parchment paper and wax paper can be effective substitutes. 

If you are using foil, you should wrap the meat for the first 10 minutes of cooking and then unwrap it for the last 15 minutes.

Step-by-step Guide On How To Cook Pork Tenderloin in Oven Without Foil

The steps below will teach you how to effectively prepare tenderloin in an oven without using foil.

Step #1: Marinating the Pork Tenderloin

Prepare the marinade by mixing the ingredients evenly and then pour it over the pork tenderloin and ensure it spreads over all the surfaces. Put the pork tenderloin in a sealable plastic bag

Ziplock bag, or in a bowl, cover it with a lid and then allow it to marinate in the fridge.

Seal the bag or lid tightly to remove as much air as you can, this will allow the seasoning used to coat all parts of the tenderloin.

To get perfect results, let the pork tenderloin marinate for 4-24 hours. However, if you are in a haste, you can allow it to marinate for one hour and still get an irresistible flavor.

Cutting back on the time for marinating will reduce its juiciness and flavor.

Some of the best marinades you can use are Sesame ginger, Balsalmic Rosemary, Soy sauce, and Maple Dijon.

Can you marinate pork tenderloin for too long? 

Yes, you can. According to, pork tenderloin can be safely marinated in the refrigerator for 5 days.

Note: A good marinade is the secret to juicy, tender, and flavorful pork tenderloin.

Step #2: Searing the Pork Tenderloin

The purpose of searing is to enhance the flavor of the tenderloin and seal the fluids before you start baking.

While at it, be careful not to overcook it so it can remain edible.

The heat from the searing process caramelizes the marinade on the pork. The resultant brown coating on the meat indicates that the process is now complete.

searing the meat

To sear it, get an oven-safe pan and add the olive oil. Heat it to about 350 degrees F (175 degrees C) and drain the excess and unuseful marinade.

Lay one side of the tenderloin on the pan and heat for about 5 minutes at the same temperature. Alternatively, you can just stop stirring after the color changes to a golden brown.

Turn to the other side of the pork tenderloin and repeat the process.

You may prefer to sear all four sides as some chefs do. However, searing the two opposite sides is enough to get a good outcome.

Tip: Buy a meat thermometer to ensure you get the perfect result.

Step #3: Baking the Pork Tenderloin

You don’t need extra equipment for this stage. The skillet you used for steering is sufficient.

Now that you have seared the pork tenderloin, apply some extra marinade to it. 

Place it in an oven or a baking dish that has been preheated to about 350 degrees F. Bake it till it reaches a temperature of about 425 degrees F.

Remove the pork tenderloin after about 25 minutes or until the center of the pork is no longer pink.

Note: The temperature and duration recommended for baking ensure the meat quickly becomes tender and doesn’t dry out or overcooked.

Step #4: Resting the Pork Tenderloin

Let it rest for about 10 minutes before serving to allow it to absorb all the marinade.

Don’t hurry. Skipping this process to slice the pork tenderloin immediately after baking will make it lose its juices and become dry.
