Oven Baked Pork Tenderloin
There’s something so homey about an oven roasted pork tenderloin served with a side of roasted veggies. It’s delicious, filling, healthy and uses just a few simple ingredients. Pork tenderloin is one of our favorite cuts of meat. It’s inexpensive, and no matter how you cook it, it’s virtually impossible to mess it up.
For this recipe, we have gone super simple, seasoning with thyme, rosemary, sage, garlic and onion powder. No marinades and no crazy ingredients. If you are a fan of the flavors, it wouldn’t hurt to toss in a pinch or two of Italian seasoning blend, cumin or paprika.
Ingredients in Pork Tenderloin and Potatoes
- Pork tenderloin - these typically come about 1 to 1 ½ pounds each. You can also use very small pork tenderloins or double the ingredients and make this recipe with very large pork tenderloins. It's very versatile.
- Salt and Pepper
- Butter - make sure your butter is at room temperature so it will mix and spread easily.
- Garlic - we like the flavor of fresh minced garlic for this herb butter.
- Thyme and Rosemary - we highly recommend using fresh herbs here. However, if you can’t find them fresh then dried will work great.
- Sage - dried sage works great, or you can substitute about double the amount of chopped fresh.
- Onion Powder - this adds a nice sweet onion flavor to the butter. You could also add a little garlic powder if you like.
- Onions - we like to use yellow onions, but both white or red will work.
- Carrots - these should be peeled and cut into 2” pieces.
- Potatoes - we suggest using fingerling potatoes, red potatoes, yukon gold potatoes or a mix of all.
- Avocado Oil - you can also substitute olive oil if you’d like.
- Parsley - we like to use fresh parsley as a garnish, but this is completely optional.
How to Make Pork Tenderloin and Potatoes
- Prepare pork. Spray a 9" x 13" baking dish with non-stick cooking spray. Unwrap the pork tenderloin and place it in the baking dish. Use a paper towel to pat dry the pork tenderloin, then season with salt and pepper.
- Make the herb butter. In a small bowl, combine the room temperature butter, garlic, thyme, rosemary, sage, and onion powder and use a fork to mash and combine all of the ingredients. Using a spatula, spread this butter mixture evenly over the top of the pork tenderloin.
- Prepare veggies. In a separate bowl, add the prepared onions, carrots, potatoes, avocado oil, and 1 teaspoon of reserved minced garlic. Stir until well coated, then arrange the veggies around the edge of the pork in the baking dish.
- Roast. Roast in a preheated 400 degree oven for 35-40 minutes, or until the thermometer reads 145 degrees F. If the pork isn't golden brown on top, broil in the oven for a minute or two until golden. Once the pork has reached 145 degrees, remove from the oven and let rest for about 10 minutes before slicing and serving.
- Serve. To serve, spoon juices from the bottom of the baking dish over the meat. Slice the pork into 1" pieces, garnish with freshly chopped parsley and serve with some of the roasted vegetables and any other of your favorite sides. Enjoy!

The cook times will vary depending on the size of the pork tenderloin and your own oven, but generally at 400 degrees, we have found that it takes about 90 minutes to roast 3 pounds of pork tenderloin. Keep in mind you should always rely on the internal temperature and not the listed cook time when cooking meat!
For pork tenderloin, the internal temp must reach 145 degrees F in order to be considered safe to eat. If you aren’t using boneless pork, you want to be sure that your meat thermometer is not touching any bone. It is ok if there is a little pink in the middle.
Absolutely! Any one of our slow cooker pork recipes would work great with pork tenderloin.
These are actually two different cuts of meat and therefore need to be cooked differently. Pork tenderloin comes from a muscle near the spine of the animal while pork loin comes from the ribs. Since the tenderloin is an infrequently used muscle, this cut of pork becomes melt in your mouth tender and juicy when roasted.
