    Roasted Pork Loin

    Roast pork loin is a simple dish where a large pork loin weighing 2 pounds or more is roasted until the desired internal temperature is achieved. A pork loin is a long wide cut that is between the back and ribs. It can be boneless or bone-in. When slicing the loin into individual cuts, it will render pork chops.

    There are many ways to prepare a pork loin, and roasting them is a great easy way to do so. These procedures of dry brining and basting in herb butter will render a flavorful, juicy, tender pork loin every single time.

    Ingredients and Substitutions

    pork loin ingredients
    • Pork – You will use a boneless pork loin for this recipe.
    • Herbs – I used a combination of fresh rosemary and thyme, which is used for the basting butter.
    • Onions – Shallots and garlic are used for the butter and sauce. You can substitute the shallot for a red, white, yellow, or sweet onion.
    • Butter – I always use unsalted butter in my cooking and baking so that I control the salt content.
    • Mustard – You will need whole-grain mustard for this recipe. I like the brand Maille.
    • Cherries – Use dried tart cherries. You can try and use pitted fresh cherries. 
    • Stock – You will need a good beef stock for the sauce.

    How to Make a Roasted Pork Loin

    Start by trussing the pork loin. See the video below on how to do this.

    trussing a pork loin

    Place the trussed pork loin on a sheet tray with a rack and generously season it on all sides with salt and pepper. Put the pork on the rack in the refrigerator uncovered for 24 hours and up to 48 hours.

    seasoning a pork loin

    Make the herb butter by whipping the softened unsalted butter in a stand mixer with the paddle attachment on high speed for 5 to 7 minutes or until it becomes light and fluffy. Turn the speed to low and add in the garlic, thyme, rosemary, salt, and pepper until combined. Set it aside.

    adding garlic and herbs to a mixer

    In a large sauté pan with olive oil, heat it over high heat until it begins to smoke. Place the pork into the pan, fat cap side down, turn the heat down to medium, and sear for 3-4 minutes or until well browned.

    Give the pork a quarter turn and cook for 2 to 3 minutes or until well browned. Repeat the process on the direct other side until well browned. Turn the pork to seared fat cap side up, turn the heat down to low, and cook for 1 minute.

    cooking a pork loin on all sides

    Add in 3 tablespoons of the herb butter.

    Baste the pork with a large spoon for 3 to 4 minutes.

    basting a pork loin

    Place the pork in the oven at 300° and cook for 32-35 minutes or until it reaches an internal temperature of 130° to 135°.

    Set the pork on a plate or cutting board and rest for 15 minutes.

    Drain half the fat from the pan and return the pan to a burner over medium heat. Stir in the shallot and cook sauté for 2 to 3 minutes or until lightly browned.

    Make-Ahead and Storage

    Make-Ahead: While this is meant to be eaten as soon as it comes out of the oven and is sliced, you can make this 30 minutes ahead of time while keeping it warm in an oven at 165°. You can only do this if you prefer the pork loin to be well done internally.

    How to Store: Place covered in the refrigerator for up to 4 days. This will freeze covered for up to 2 months. Thaw in the refrigerator for one day before reheating.

    How to Reheat: Please note that reheating pork will cause it to overcook immediately. The best way to heat it is in a pan or a sheet tray lined with parchment paper in the oven at 350° for 6-8 minutes or until warm. Heat the sauce separately in a small saucepot over low heat until warm.

    Chef Notes + Tips

    • It’s important to rest this pork, or any protein, after cooking to allow for the juices to soak back into it, making it more flavorful.
    • If the herbs and spices start to burn in the pan, then turn the heat down more. It will just take a few more minutes to cook.
    • To serve the pork loin at a medium internal temperature, you will want to take it out of the oven when it reaches 135°. With carry-over cooking, the pork will advance in temperature while resting at or above 140° to 145°, making it a perfect medium internal temperature.
    • You will have some herb butter leftover to use in another recipe later. The butter freezes well.
