Pork tenderloin is a fantastic, lean cut of meat that’s perfect for a hands-off cooking method like the crock pot. But figuring out *exactly* how long to cook a 1.5 lb pork tenderloin in a crock pot can be tricky. Don’t worry, this guide will walk you through everything you need to know to achieve perfectly cooked, tender, and juicy pork every single time.
**Why Use a Crock Pot for Pork Tenderloin?**
Crock pots, also known as slow cookers, are amazing for several reasons:
* **Convenience:** Set it and forget it! You can prep your pork in the morning and come home to a delicious dinner.
* **Tenderness:** The low and slow cooking process breaks down tough fibers, resulting in incredibly tender meat.
* **Flavor:** Pork tenderloin soaks up all the delicious flavors of the cooking liquid and seasonings.
* **Easy Cleanup:** One-pot cooking means less mess to clean up afterward.
**Factors Affecting Cooking Time**
Several factors can influence how long it takes to cook a 1.5 lb pork tenderloin in your crock pot:
* **Crock Pot Model:** Different crock pots cook at slightly different temperatures. Some newer models tend to cook hotter and faster.
* **Crock Pot Setting:** Cooking on low will take longer than cooking on high.
* **Internal Temperature:** The most important factor! Pork tenderloin is safe to eat at 145°F (63°C).
* **Ingredients:** Adding cold vegetables can slightly increase cooking time.
**Recommended Cooking Times**
As a general guideline, here are the recommended cooking times for a 1.5 lb pork tenderloin in a crock pot:
* **Low Setting:** 3-5 hours
* **High Setting:** 2-3 hours
*Important Note:* Always use a meat thermometer to ensure the pork reaches an internal temperature of 145°F (63°C). Cooking times are estimates only.
**Step-by-Step Instructions**
Here’s a simple guide to cooking a 1.5 lb pork tenderloin in your crock pot:
1. **Prep the Pork:** Trim any silver skin from the pork tenderloin. This tough membrane can make the meat chewy.
2. **Season the Pork:** Generously season the pork with your favorite spices. Some popular options include salt, pepper, garlic powder, onion powder, paprika, and herbs like thyme or rosemary. You can also use a pre-made pork rub.
3. **Sear the Pork (Optional):** Searing the pork in a hot skillet before adding it to the crock pot adds a beautiful color and locks in flavor. This step is optional but highly recommended.
4. **Add to Crock Pot:** Place the seasoned (and seared, if desired) pork tenderloin in the crock pot.
5. **Add Liquid:** Pour in enough liquid to cover the bottom of the crock pot. This could be chicken broth, beef broth, apple juice, wine, or even water.
6. **Add Vegetables (Optional):** Add your favorite vegetables to the crock pot. Potatoes, carrots, and onions are great choices. Place them under the pork so they cook evenly.
7. **Cook:** Cover the crock pot and cook on low for 3-5 hours or on high for 2-3 hours.
8. **Check Temperature:** Use a meat thermometer to check the internal temperature of the pork. It should reach 145°F (63°C).
9. **Rest:** Once cooked, remove the pork tenderloin from the crock pot and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
**Tips for Success**
* **Don’t Overcook:** Overcooked pork tenderloin can become dry and tough. Use a meat thermometer and check the temperature regularly.
* **Use a Meat Thermometer:** A meat thermometer is your best friend when cooking pork tenderloin. It ensures the pork is cooked to a safe temperature without being overcooked.
* **Don’t Peek:** Resist the urge to open the lid of the crock pot frequently. This releases heat and can increase cooking time.
* **Thicken the Sauce (Optional):** If you want a thicker sauce, remove the pork tenderloin and vegetables from the crock pot. Mix a tablespoon of cornstarch with two tablespoons of cold water to form a slurry. Stir the slurry into the cooking liquid in the crock pot. Cover and cook on high for 15-20 minutes, or until the sauce has thickened.
**Serving Suggestions**
Pork tenderloin cooked in the crock pot is incredibly versatile. Here are some serving suggestions:
* **Sliced as a main course:** Serve with your favorite sides, such as mashed potatoes, roasted vegetables, or a salad.
* **In sandwiches:** Slice the pork and use it for delicious sandwiches or sliders.
* **In tacos or burritos:** Shred the pork and use it as a filling for tacos or burritos.
* **In salads:** Add sliced pork to salads for a protein-packed meal.
