Before you start

Before you begin, ensure your slow cooker insert is clean and dry. Remove the pork tenderloin from the refrigerator about 20 minutes before you are ready to start, allowing it to take the chill off slightly, which helps with more even cooking.

Have your peach slices and Dijon mustard ready to go. There is no need to sear the pork beforehand, as the slow cooker method relies on the braising liquid to develop the flavor and texture of the meat throughout the cooking time.

Ingredients at a glance (4)
  • 1 lb pork tenderloin, trimmed of excess fat
  • 1 cup peach slices in syrup
  • 1 tsp dried thyme
  • 2 tbsp Dijon mustard

Instructions

Preparation and Setup

  1. Prepare the slow cooker
    Place the raw pork tenderloin into the insert of your slow cooker. Ensure the meat is positioned flat to allow for even heat distribution during the cooking process.
    Look for The pork lies flat on the bottom.
    Tip Avoid overcrowding the slow cooker if doubling the recipe.

At this stage, the pork tenderloin is neatly placed in the slow cooker, ready to be seasoned. The goal is to establish a stable foundation for the cooking process by ensuring the meat is positioned correctly.

No heat has been applied yet, and the ingredients are waiting to be combined. Ensure your workspace is clear of any raw meat contaminants before proceeding to the seasoning steps to maintain a safe and organized kitchen environment for the remainder of the recipe.

Adding Aromatics

  1. Add the aromatics and sauce
    Pour the peach slices along with their syrup over the pork. Sprinkle the dried thyme evenly over the peaches and meat. Finally, spoon the Dijon mustard directly on top of the tenderloin.
    Look for The peaches and mustard cover the pork surface.
    Tip Spread the mustard slightly to ensure even coating.

Now, the pork is topped with the peach slices, dried thyme, and Dijon mustard. The ingredients should be distributed evenly over the top of the meat to ensure that the flavors permeate the pork as it cooks. The slow cooker is now ready to be covered and turned on. The aroma of the mustard and fruit should be faintly noticeable, and the components are layered so that the juices will naturally cascade over the pork during the slow braising phase.

Slow Cooking and Finishing

  1. Cook and serve
    Cover and cook on low for 4 hours until the pork reaches an internal temperature of 145°F (63°C). Once cooked, remove the pork to a cutting board and let it rest for 5 minutes before slicing. Spoon the remaining peach Dijon sauce from the slow cooker over the sliced meat.
    Look for The surface is soft and braised with a thick sauce.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Use a meat thermometer to verify the internal temperature.

The pork has been slow-cooked until it reached the required internal temperature of 145°F (63°C). The meat should be tender, and the peach Dijon sauce should be slightly thickened with a glossy appearance. After the required resting period, the pork is ready to be sliced against the grain. The final dish should look succulent, showing a soft, braised texture with a vibrant sauce that is ready to be served immediately while still warm and aromatic.

Common mistakes

A common mistake is overcooking the pork tenderloin, which can lead to a dry texture despite the liquid in the slow cooker. Be sure to use a thermometer to check for doneness rather than relying solely on the clock, as slow cooker models vary in heat intensity.

Another error is failing to trim the silver skin, which will remain chewy even after hours of cooking. Finally, resist the urge to lift the lid too often during the process, as this releases heat and moisture.

How to tell it’s done

The pork tenderloin is perfectly done when it reaches an internal temperature of 145°F (63°C) at the thickest part. You will notice that the meat has a soft, braised surface and the sauce has reduced into a thick, pourable consistency.

Using a digital meat thermometer is the most reliable way to ensure the pork is safe to eat while maintaining its tenderness. Always allow the meat to rest for at least 5 minutes before slicing, as this ensures the juices redistribute back into the fibers.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
