The key with tenderloin is making sure it’s not overcooked, which is when it gets dry. The riper the peaches, the more delicious and nuanced the sauce will be.

Ingredients

8 servings

Peach-Mustard Sauce:

2 large ripe peaches, peeled, cut into small pieces
1/4 cup ketchup
3 Tbsp. Dijon mustard
1 tsp. light brown sugar
1/2 tsp. freshly ground black pepper
1/2 tsp. (or more) kosher salt

Pork:

2 pork tenderloins (about 1 lb. each)
4 tsp. kosher salt
1 tsp. freshly cracked black pepper
Vegetable oil (for grill)
1/2 cup peach preserves, warmed
  1. Peach-Mustard Sauce:

    Step 1

    Purée peaches, ketchup, mustard, brown sugar, pepper, and 1/2 tsp. salt in a blender until mixture is smooth and creamy. Taste sauce and season with more salt if needed.

  2. Pork:

    Step 2

    Sprinkle pork with salt and pepper and rub all over. Let sit at room temperature 1 hour. Meanwhile, prepare a grill for medium heat and brush grate with oil.

    Step 3

    Brush pork with some preserves. Grill, turning every 4 minutes or so and brushing with any remaining preserves, until charred on all sides and an instant-read thermometer inserted into the thickest part registers 130°F, 10–12 minutes. Transfer to a cutting board and let rest 10 minutes. Slice 1/2" thick.

    Step 4

    Serve sliced pork with Peach-Mustard Sauce alongside.

  3. Do Ahead

    Step 5

    Sauce can be made 1 day ahead. Cover and chill.

  • Based on the other reviews, I cut back on the mustard but felt the recipe still needed a lot of work. I added a few good squeezes of lemon juice and a dash of Worcestershire sauce, then cooked it down to concentrate the flavours. It’s better but I might still add some Ras Al Hanout to give it more character.

  • Made this for PeachFest 2018 (that's not a thing - I just made it up as an excuse for a fun themed dinner). The sauce is way too mustardy - you can't even taste the peaches. Just put out the dijon mustard and don't even bother. I might make it again but cut way back on the mustard. Then the grilling method - we followed the instructions but the preserves just slid off the roast not enough stayed behind to give any flavor. The pork tasted fine but not because of the recipe - it's just grilled pork. I might make it again but with substantial modifications.

  • This was delicious! When I make it again, I will leave out the brown sugar and add a bit of "heat" to the sauce.
