Preparation Methods
Marinating: This technique involves soaking the pork in a flavorful liquid mixture to enhance taste and tenderness. It's important for this dish as it allows the pork to absorb a depth of flavor. For best results, marinate the pork overnight in the refrigerator.
Searing: Before placing the pork in the slow cooker, searing it in a hot pan helps to lock in juices and create a flavorful crust. Use high heat and a small amount of oil, turning the meat until all sides are browned.
Layering Ingredients: Proper layering in the slow cooker ensures even cooking and flavor distribution. Place denser vegetables like onions and carrots at the bottom, with the pork on top to allow juices to circulate.
Step 1: Prepare Ingredients

Gather all ingredients and ensure they are measured accurately.
Trim excess fat from the pork tenderloin to prevent greasiness.
Mince the garlic and chop the rosemary finely for the marinade.
Slice the onion and carrots into uniform pieces for even cooking.
Step 2: Create the Marinade

In a medium bowl, combine soy sauce, honey, olive oil, minced garlic, and chopped rosemary.
Whisk the ingredients together until the honey is fully dissolved.
Ensure the mixture is well combined to evenly coat the pork.
Pour half of the marinade into a large resealable plastic bag.
Step 3: Marinate the Pork

Place the pork tenderloin into the bag with the marinade.
Seal the bag, removing as much air as possible to ensure the marinade fully surrounds the meat.
Refrigerate the pork for at least 2 hours, or overnight for maximum flavor.
Turn the bag occasionally to redistribute the marinade.
Step 4: Sear the Pork

Remove the pork from the marinade and pat dry with paper towels.
Heat a tablespoon of oil in a large skillet over medium-high heat.
Sear the pork until golden brown on all sides, about 2-3 minutes per side.
Transfer the seared pork to a plate and set aside.
Step 5: Prepare Slow Cooker

Slice onions and carrots and place them at the bottom of the slow cooker.
Pour the remaining marinade and chicken broth over the vegetables.
Stir gently to combine the liquids and vegetables evenly.
Add salt and pepper to taste, ensuring the base is well seasoned.
Step 6: Add Pork to Slow Cooker

Place the seared pork tenderloin on top of the vegetable bed in the slow cooker.
Cover the slow cooker with the lid, ensuring it is securely in place.
Set the slow cooker to low heat for 4 hours.
Occasionally check to ensure the liquid is gently simmering.
Step 7: Monitor and Adjust

Check the pork's internal temperature after 3.5 hours with a meat thermometer.
Ensure it reaches at least 145°F for safe consumption.
Adjust cooking time if necessary, based on the thermometer reading.
Avoid lifting the lid frequently, as it releases heat and moisture.
Step 8: Rest and Slice

Once cooked, remove the pork from the slow cooker and let it rest for 10 minutes.
Resting allows the juices to redistribute for maximum tenderness.
Slice the pork into 1/2-inch thick pieces for serving.
Arrange slices on a warm platter for presentation.

• Flavors Unbalanced: Occurs if marinade ingredients are not well mixed. Ensure thorough whisking of the marinade.
• Overcooked Vegetables: Can result from too long cooking time. Use larger vegetable pieces to withstand slow cooking.
• Burned Crust: Results from excessive searing time. Monitor closely and remove from heat once a crust forms.

Food Science Behind the Recipe
• Maillard Reaction: This chemical reaction occurs during searing, creating a flavorful crust through browning amino acids and sugars.
• Collagen Breakdown: Slow cooking helps break down collagen in the pork, resulting in a tender, juicy texture.
