Ingredients
  

  • 2 pork tenderloins (about 1 to 1.5 pounds each)
  • 1 tablespoon olive oil (for searing)
  • 6–8 cloves garlic, minced
  • 2 teaspoons kosher salt (or to taste)
  • 1 teaspoon black pepper
  • 1 tablespoon Dijon mustard
  • 1 tablespoon honey (optional, balances the savory notes)
  • 1 tablespoon fresh rosemary, chopped (or 1 teaspoon dried)
  • 1 tablespoon fresh thyme, chopped (or 1 teaspoon dried)
  • 1 teaspoon dried oregano
  • 1 cup low-sodium chicken broth
  • 2 tablespoons soy sauce (or coconut aminos for gluten-free)
  • 2 tablespoons butter (optional, for finishing the sauce)
  • 1 tablespoon cornstarch + 1 tablespoon water (optional slurry for thickening)
  • Fresh parsley, chopped (for garnish)
  • Lemon wedges (optional, a squeeze brightens the sauce)

Method
 

  1. Pat dry and season. Pat the pork tenderloins dry with paper towels. Season all over with salt and pepper.
  2. Sear for flavor. Heat olive oil in a large skillet over medium-high. Sear the tenderloins 1–2 minutes per side until golden. This step adds depth and helps lock in juices.
  3. Mix the sauce base. In a small bowl, stir together garlic, Dijon, honey, rosemary, thyme, oregano, chicken broth, and soy sauce.
  4. Load the crockpot. Place the seared tenderloins in the slow cooker. Pour the sauce mixture over the top, making sure the pork is nestled into the liquid.
  5. Cook low and slow. Cover and cook on Low for 2.5–3.5 hours, or on High for 1.5–2 hours. Aim for an internal temperature of 145°F (63°C) at the thickest part.
  6. Rest and slice. Transfer pork to a cutting board and let rest for 5–10 minutes. Slice into medallions against the grain.
  7. Finish the sauce. Pour cooking juices into a small saucepan. Stir in butter for a glossy finish. If you prefer a thicker sauce, bring to a simmer and whisk in the cornstarch slurry. Cook 1–2 minutes until slightly thickened.
  8. Serve. Spoon the garlic herb sauce over the sliced pork. Garnish with parsley and a squeeze of lemon if you like. Serve with mashed potatoes, rice, or roasted vegetables.
