Lemon-Dijon Pork Tenderloin

Lemon-Dijon Pork Tenderloin

Recipe courtesy Ina Garten, originally called “Herb-Marinated Pork Tenderloins.”

I changed the name, but not the recipe. As soon as I read the ingredient list, my mouth began to water. I am not typically one for dijon, but I do like it as a marinade ingredient. This dish was so good, that it’s making me hungry just thinking about it again.

My only experience with Pork Tenderloin in the past was a pre-marinated one I had purchased from the store. It was so salty that Jake and I couldn’t even finish it. So, when we were at Bill the Butcher again last weekend, I was inspired to do my own from scratch. My only problem was that we only bought one tenderloin. This recipe was so freaking succulent that I should have purchased 3 and saved the rest for leftovers.

The ingredients for this marinade are enough for 3 Tenderloins. It measured 1.5 cups liquid when it was done, so I just used 1/2 cup for my one lonely Tenderloin and reserved the rest to use for something else.

Chef’s Tip: Plan ahead for this one! Marinate the meat the night before for extra-deliciousness.

Marinade Ingredients, fresh and flavorful!


  • 1 Lemon, zest grated
  • 3/4 Cup freshly squeezed lemon juice (4-6 lemons – but it only took 3 extra-large lemons for me)
  • Good Olive Oil
  • 2 Tablespoons minced Garlic (6 cloves)
  • 1 1/2 Tablespoons minced fresh Rosemary leaves
  • 1 Tablespoon chopped fresh Thyme leaves
  • 2 Teaspoons Dijon mustard
  • 2 Teaspoons Sea Salt
  • 3 Pork Tenderloins (about 1 pound each)
  • Freshly ground black pepper

Your finished marinade should look something like this.


  • Combine the lemon zest, lemon juice, 1/2 cup olive oil, garlic, rosemary, thyme, mustard, and 2 teaspoons salt in a sturdy 1-gallon resealable plastic bag. Add the pork tenderloins and turn to coat with the marinade. Squeeze out the air and seal the bag. Marinate the pork in the refrigerator for at least 3 hours but preferably overnight.
  • Preheat oven to 400.
  • Remove the tenderloins from the marinade and discard the marinade but leave the herbs that cling to the meat. Sprinkle the tenderloins generously with salt and pepper (maybe a bit less on the salt here!).
  • Heat 3 tablespoons olive oil in a large oven-proof sauté pan over medium-high heat.
  • Sear the pork tenderloins on all sides until golden brown. (About 2 minutes per side).
  • Place the sauté pan in the oven and roast the tenderloins for 10-15 minutes or until the meat registers 137 degrees at the thickest part. (It only took ours 10 minutes!)
  • Transfer the tenderloins to a platter and cover tightly with aluminum foil. Allow to rest for 10 minutes. (We skipped this part entirely.)
  • Carve in 1/2-inch-thick diagonal slices. The thickest part of the tenderloin will be quite pink (it’s just fine!) and the thinnest part will be well done.
  • Season with salt and pepper and serve warm, or at room temperature with the juices that collect in the platter.

Roasted Veggies make a perfect side dish!


Happy eating! Joey


    • I agree! Jake & I actually get frustrated watching the Food Network because there are so many dishes we don’t eat. I do like seeing how they cook their meats though…

    This was SO good! I can’t wait to make it again!

    AND I agree about the food network show. . .I don’t think anybody’s done a paleo program yet. . . I’m waiting to try some more things off of your blog. Needless to say, you’ve been bookmarked : )

    This was amazing! I have always made tenderloin with some type of sweet sauce (brown sugar and ginger, etc), but since going paleo, I needed a new way to do it. This was so good and I did not miss the sugar at all. I’m so excited that I made two and have leftovers for tomorrow. Thanks!

    I googled paleo pork loin recipes to use the extra one in the freezer. This jumped out at me instantly. Excited to explore your site some more! Also excited for dinner tonight :D

    • I like to toss them in melted Kerrygold Herb Butter (as much as needed to coat the veggies), sprinkle with sea salt & cracked pepper, and usually roast them on a baking sheet in the oven at 415 for 12 minutes. They come out absolutely delicious! You can also BBQ them on the grill for about 5-7 minutes if you want.
