Ingredients

Pork and Seasoning

  • 1 pork tenderloin about 1.5 pounds
  • 1 tsp garlic powder
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1 tsp dried rosemary
  • 1 tsp dried sage

Cooking and Sauce

  • 2 tbsp olive oil
  • 1 cup chicken broth
  • 2 tbsp Dijon mustard
  • 2 tbsp butter
  • 1/4 cup white wine
  • 1/2 cup heavy cream
  • 1 tbsp all-purpose flour
  • 1 tsp fresh thyme chopped
  • 1 tbsp fresh parsley chopped

Instructions

  1. Season the Pork: Rub the pork tenderloin evenly with garlic powder, salt, black pepper, dried rosemary, and dried sage to infuse the meat with herbaceous and savory flavors.
  2. Sear the Pork: Heat olive oil in a large skillet over medium-high heat. Sear the pork tenderloin on all sides until it achieves a golden brown crust, about 2-3 minutes per side. This step locks in juices and adds depth of flavor.
  3. Transfer to Slow Cooker: Place the seared pork tenderloin into your slow cooker and pour in 1 cup of chicken broth around the meat to keep it moist during slow cooking.
  4. Add Dijon Mixture: In a small bowl, combine Dijon mustard, butter, and white wine. Pour this flavorful mixture over the pork in the slow cooker to enrich the cooking liquid and enhance the final taste.
  5. Slow Cook the Pork: Cover and cook on LOW for 8 hours until the pork is tender and cooked through, allowing flavors to meld beautifully.
  6. Rest the Pork: Remove the pork from the slow cooker and allow it to rest for a few minutes to let the juices redistribute for moist slices.
  7. Prepare the Sauce: Pour the cooking liquid into a saucepan and bring it to a simmer over medium heat. Gradually whisk in the heavy cream and all-purpose flour until the sauce thickens to a creamy consistency.
  8. Add Fresh Herbs: Stir in fresh chopped thyme and parsley to brighten the sauce and add fresh herbal notes.
  9. Serve: Slice the pork tenderloin and drizzle generously with the creamy Dijon and herb sauce for an elegant and comforting presentation.

Notes

  • Searing the pork before slow cooking adds important flavor and texture but can be skipped for convenience; however, the dish will be less rich.
  • If you prefer a thicker gravy, increase the flour to 1.5 tablespoons and adjust the cream accordingly.
  • Use fresh herbs if possible, but dried herbs can be substituted at about one-third the amount.
  • Allow the pork to rest after cooking to ensure juicy, tender slices.
  • Serve with mashed potatoes or roasted vegetables to complement the creamy sauce.
