These tips for how to cook tenderloin in the oven will help you get a perfect dinner, no matter what herbs or marinades you use with it.

While this easy recipe requires no special equipment, there are a couple tried and true kitchen favorites that help making this dish so much easier - no matter your experience level in the kitchen!

• Baking sheet. Any large baking sheet, casserole dish, or oven-safe vessel will work - make sure it has a bit of a lip in case you spill a little of the garlic butter out of the foil pouch when cooking or moving the baked pork tenderloin in/out of the oven.
• Aluminum Foil
• Large Skillet or Frying Pan
• Metal Tongs
• Meat Thermometer

I get a lot of questions on this recipe on whether to use a tenderloin or loin - and what the difference is between tenderloin and loin since they are similar cuts from the pig, and can both be used in this recipe.

The two cuts are from similar areas (off the back of the pig), and are both leaner and respond to the same cooking methods, but a tenderloin is much longer and skinnier than a loin.

Loins tend to be much fatter, much heavier, and over 3 lbs – while a tenderloin will be longer, skinnier, and around 1-2 pounds.

For this recipe, I am calling for a Pork Tenderloin – but a loin will also work with the modification for time below. If you're going for a one-pot pork loin dinner, please check out my knockout Garlic Herb Butter Pork Loin and Potatoes recipe!

To make this recipe with a loin, which is larger and thicker than a tenderloin, continue with the recipe exactly as called for below, but plan on an additional 20-30 minutes (this will vary depending on your loin - I always advocate for cooking off temperature, rather than time, when cooking meat, but this time-frame should help you plan your dinner around.)

Since tenderloin is a cut of meat that has very little fat, it can become tough very quickly when overcooked - I'm providing my best tips and tricks to bake the perfect dinner, every single time you make it.

Marinating or brining a tenderloin before cooking will always help to soften the meat and keep it from drying out.

I love using a bottle of simple Italian Dressing or a cup of olive oil with some lemon juice, salt, and pepper for an easy overnight marinade.

I'm not calling for marinade in this specific recipe because we're wrapping it in foil and slathering it in butter so it cooks in its own sort of gravy (I designed this recipe to taste great even if you didn't remember to marinate) - if you'd like to kick your dinner up a bit, or are trying a different technique, marinating makes this recipe taste even better.

Pre-seasoned tenderloins from your grocer are often dry-brined with salt beforehand, so it doesn't need additional marinating or brining.

While I prefer to make my own marinade and seasonings so I can control the flavor, if you always forget to marinate or just don't have time, this is a great way to skip that step.

Pork dries out very quickly when overcooked - and the meat can become tough and very chewy.

I pull my tenderloin at 140 degrees and tent with foil to continue carryover cooking as it rests for about 10 minutes before serving.

If your tenderloin has a large sliver skin (the tough, white membrane that is often trimmed off and removed by many grocers, but is sometimes still left on), you can remove it by making a small slit with a sharp knife and pulling the membrane off the tenderloin to remove before marinating and cooking.

This process is just like removing silver skin from ribs.

I like to take these tips to make all sorts of flavor combinations in addition - you can make this recipe with all sorts of herbs and spices!

Get a good sear in a cast iron or heavy pan before baking. Getting a good sear first helps seal in the juices from the pork and brings a rich, caramelized flavor that makes this recipe irresistible!

Searing meat before baking also helps it look less gray, giving it a much more appetizing appearance.

Let meat rest for 5-10 minutes after removing from the oven to lock in the juices - don't cut too early, or they will all run out!

The USDA set the guideline of 145 degrees as a safe temperature for pork consumption. This might look a touch pink - pink pork is no longer an indicator of "doneness", or that the tenderloin is unsafe to eat, as long as it has reached 145 degrees. Don't overcook out of fear and turn your dinner tough and dry!

Cooking to 145 means removing tenderloin from the oven at 140 degrees - as it will carryover cook the additional 5 degrees in the foil as you let it rest.

If you love this easy recipe, but can't eat it all, never fear - it is beautiful and delicious as leftovers.

Since we're baking this dinner in a garlic butter sauce, it will already have a leg up in staying juicy and tender when reheated.

To Store Leftovers

Place all leftovers in an airtight container and keep in refrigerator for up to three days.

To Freeze Leftovers

To freeze so you can eat later, place in a plastic bag or wrap in plastic wrap and keep in freezer for up to three months. Try to freeze in small batches - ideally, you will freeze in individual servings, or the amount you will need to reheat.

If you freeze a large tenderloin and go to thaw and reheat it, you shouldn't freeze again afterwards - so try to freeze only as much as you will be eating again when reheating in each freezer bag.

How To Reheat Leftovers

Let frozen leftovers thaw naturally in the refrigerator overnight, and bake at 350, wrapped in foil, until piping hot when ready to serve.

If reheating from the refrigerator, bake at 350 in a foil pouch until piping hot.

You can also pan-fry slices of pork tenderloin in a bit of butter or olive oil - simply cook on medium until very hot - and serve.

Pork can be microwaved to reheat - while it isn't our favorite method - but it can dry out and make meat tougher, so try adding a bit of stock or butter to the top of the pork with it when you microwave for the best texture.
