Tender pork tenderloin is brined for flavor and juiciness, then served with a simple sweet-and-spicy peach serrano sauce.

I love the contrast of sweet and spicy, and this pork tenderloin highlights both. Fresh Georgia peaches add natural sweetness and bright flavor, while serrano chiles bring a lively heat. The pork is briefly brined so it stays juicy and gains flavor, then seared and roasted for a caramelized crust. The peach serrano sauce comes together quickly on the stovetop and complements the pork with a balance of fruity sweetness and subtle heat. Even if you don’t usually cook pork, this method — a short brine, a hot sear, and careful roasting — produces tender, flavorful meat that’s hard to resist.

Ingredients
For the pork:
- 3 tbsp sea salt
- 3 cups warm water
- 1/4 cup vinegar red wine vinegar recommended
- 1/4 tsp red pepper flakes
- 1 tbsp molasses
- 1 cup ice cubes
- 2 pounds pork tenderloin
For the peach serrano sauce:
- 1 tbsp butter
- 2 serrano chiles minced and seeded; substitute your preferred chile if desired
- 1/2 cup peach preserves use a good-quality preserve
- 1/2 cup white wine pinot grigio suggested
- 1 ripe peach pitted and diced
Instructions
-
Preheat the oven to 400°F (200°C).
-
Trim any excess fat or silver skin from the pork tenderloins.
-
In a large resealable bag, dissolve 3 tablespoons of sea salt in 3 cups of warm water. Add 1/4 cup vinegar, 1/4 teaspoon red pepper flakes, 1 tablespoon molasses, the ice cubes, and the pork. Seal the bag and brine for exactly 20 minutes — any longer and the texture can become mushy.
-
Remove the pork from the brine and pat very dry with paper towels. Dry meat sears better and develops a rich brown crust. Season generously with cracked black pepper.
-
Heat an ovenproof skillet (cast iron works well) over high heat. Sear the pork on all sides until browned and caramelized, about 5 minutes total. Transfer the skillet to the oven and roast until the internal temperature reaches 150°F (65°C), about 10–15 minutes. Let the meat rest 10 minutes before slicing; reserve any pan juices to add to the sauce if you like.
-
While the pork rests, make the peach serrano sauce. Melt 1 tablespoon butter in a skillet and sauté the minced, seeded serrano chiles for about 5 minutes until softened. Add 1/2 cup peach preserves, 1/2 cup white wine, and the diced fresh peach. Cook over high heat until the sauce thickens, about 5 minutes. Stir in any reserved pan juices for extra flavor, if desired.
-
Slice the pork and spoon the peach serrano sauce over the top. Serve immediately and enjoy.
