Roasted Veggies

Veggies

For my veggies I prefer green beans, broccolini or a combination of Roasted Vegetables. For these you’ll need your veggie of choice plus olive oil, sea salt and ground black pepper.

How to Make Juicy Pork Tenderloin with Mushroom Sauce

The Pork

Always start by getting that pork tenderloin prepped and ready to go.

Heat the oven to 400° and a skillet on medium high heat on the stove. Line a baking sheet with a non stick baking mat. Tenderize the pork by stabbing it all over with the tip of a sharp knife or by using a tenderizer.

In a little bowl combine the pork spices, then massage into the pork, all over each surface. Once the skillet is hot, sear the pork for a minute or so on each side to get those nice dark marks.

If you want to make Roasted Vegetables, prep these and add to the baking sheet, leaving room in the center for the pork. Otherwise, you’ll pan fry the green beans or broccolini, if that is what veggie you choose to pair with this dish.

Place the seared pork onto the baking sheet and bake in the preheated oven for about 15 minutes, until internal temperature reaches 145°. Let the pork tenderloin rest on the counter for 5-10 minutes before slicing into 1 inch rounds to serve.

The Mushroom Sauce

While the pork tenderloin is baking in the oven, it’s time to make the mushroom sauce!

Wash the mushrooms thoroughly, then chop into thin slices. Dice the onion and mince the garlic. Heat butter in a medium saucepan on medium high heat and once melted, add the prepared mushrooms, onion, garlic, black pepper and sea salt. Stir constantly and cook for 8-10 minutes, until the mushrooms have browned.

Deglaze the saucepan by adding 1/2 cup beef broth and scraping all of the little browned bits off the bottom with a wooden spoon. Turn the heat off and stir in the remaining 1/2 cup beef broth.

Using an immersion blender, puree the mushroom sauce until smooth, or skip this step if you like a chunky sauce. Stir in the sour cream and heavy whipping cream, then warm the sauce just until hot.

Veggies

Roasted Vegetables

If it’s a combination of roasted veggies you’re after, check out this Roasted Vegetables recipe, and add it to the baking sheet with the pork tenderloin. You may need to remove the pork from the baking sheet to rest on a cutting board so that the veggies can be placed back in the oven to bake longer than 15 minutes.

Green Beans

I looooove green beans and think they are the perfect veggie to pair with pork tenderloin. To prepare these, simply wash them and then trim the ends off.

When the pork tenderloin comes out of the oven to rest, heat a skillet on medium heat, add olive oil and, once hot, add the prepared green beans. Sprinkle with the sea salt and black pepper. Fry for a couple of minutes, then add a splash of water and cover with a lid. Allow the green beans to steam for 5 minutes.

Broccolini

Such a delicious option and so easy to make!

Once the pork comes out of the oven to rest, heat a skillet on medium heat, add olive oil and, one hot, add washed broccolini. Sprinkle with sea salt and ground black pepper. Fry in the hot pan until the broccolini is bright in colour and has some dark roasted marks, about 5 minutes.

Expert Tips to make this perfect the very first time

  1. Make sure the skillet is nice and hot when the tenderloin is added, otherwise you won’t get those nice sear marks.
  2. Deglaze the pot well with the beef stock- this helps to prevent the sauce from burning!
  3. If the sauce isn’t thick after it has been pureed, heat the sauce back up to a simmer and allow to reduce until nice and thick before adding the sour cream and heavy whipping cream – this should only happen if the pot wasn’t super hot when the beef stock was added to deglaze the pot. (the liquid should evaporate rather quickly when first added)
  4. Don’t have an immersion blender? The sauce can be cooled enough to pour into a blender to puree, or the sauce can be eaten as a chunky mushroom sauce.

Ingredients

    The Pork

    • Heat the oven to 400° and a skillet on medium high heat on the stove. Line a baking sheet with a non stick baking mat or tin foil. Tenderize the pork by stabbing it all over with the tip of a sharp knife or by using a tenderizer.
    • In a little bowl combine the sea salt, pepper, garlic powder, onion powder, then massage into the pork, all over each surface. Once the skillet is hot, sear the pork for a minute or so on each side to get those nice dark marks.
    • If you want to make Roasted Vegetables, prep these and add to the baking sheet, leaving room in the center for the pork. Otherwise, you'll pan fry the green beans or broccolini near the end of the cooking time, if that is what veggie you choose to pair with this dish.
    • Place the seared pork onto the baking sheet and bake in the preheated oven for about 15 minutes, until internal temperature reaches 145°. Let the pork tenderloin rest on the counter for 5-10 minutes before slicing into 1 inch rounds to serve.

      Excellent advice to cooking pork. From the looks of your photos the pork was done to perfection. There is nothing worse than drying out a good piece of meat by overcooking. I’m anxious to try that gravy, looks like the perfect addition.
