Pork Tenderloin with Peach-Mustard Sauce

This succulent pork tenderloin with peach-mustard sauce is a vibrant, high-protein dish that perfectly balances savoury notes with the natural sweetness of summer fruit. The tenderloin is seasoned and glazed with peach preserves before being grilled to juicy perfection, resulting in a beautifully charred exterior. Paired with a smooth, homemade sauce made from fresh peaches and tangy Dijon mustard, it offers a sophisticated flavour profile that feels both fresh and indulgent.

Ideal for a garden dinner or a healthy midweek meal, this dish is as nutritious as it is flavourful. The sauce can be prepared a day in advance and kept in the fridge, making the final assembly quick and stress-free. Serve with a crisp green salad or roasted new potatoes for a complete, balanced meal that the whole family will enjoy.

Ingredients for Pork Tenderloin with Peach-Mustard Sauce

  • 2 large ripe peaches, peeled, cut into small pieces

  • 60ml ketchup

  • 3 tablespoons Dijon mustard

  • 1 teaspoon light brown sugar

  • 1/2 teaspoons freshly ground black pepper

  • 1/2 teaspoons (or more) kosher salt

  • 2 pork tenderloins (about 450g each)

  • 4 teaspoons kosher salt

  • 1 teaspoon freshly cracked black pepper

  • Vegetable oil (for grill)

  • 120ml peach preserves, warmed

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

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.

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 54°C, 10–12 minutes. Transfer to a cutting board and let rest 10 minutes. Slice 1/2" thick.

Serve sliced pork with Peach-Mustard Sauce alongside.

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