Why I Love This Recipe
The first time I made this recipe, I was just trying to use up a pork tenderloin sitting in the fridge and a bag of root vegetables. I tossed everything into the slow cooker, added some broth and herbs, and hoped for the best.
A few hours later the house smelled incredible. When I lifted the lid, the pork was so tender it almost fell apart when I sliced it. The vegetables were soft and full of flavor from the juices.
Since then, it’s become one of those dependable meals I go back to again and again.
Why this recipe stands out:
- The pork turns incredibly tender in the slow cooker
- Root vegetables cook in the same pot and absorb the flavor
- Simple pantry spices make it taste slow-roasted
- Very little prep work
- Great for leftovers the next day
What You’ll Need
- 2 lb pork tenderloin
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- 1 tablespoon olive oil
- 2 cups diced potatoes
- 1½ cups diced carrots
- 1 medium onion, chopped
- 3 cloves garlic, minced
- 1 cup chicken broth
- 1 tablespoon Worcestershire sauce
Tools You’ll Need
- Black oval slow cooker (crockpot)
- Large skillet
- Cutting board

Pro Tips
- Sear the pork first. It adds a deeper flavor and helps seal in the juices.
- Cut vegetables evenly. Similar size pieces cook at the same speed.
- Don’t overcook the pork. Tenderloin cooks faster than pork shoulder.
- Layer vegetables under the pork. They act like a rack and soak up the juices.
Substitutions and Variations
- Swap sweet potatoes for regular potatoes.
- Use red onion instead of onion for a slightly sweeter taste.
- Add parsnips or turnips for more root vegetable flavor.
- Add rosemary instead of thyme for a stronger herb flavor.
Make Ahead Tips
You can prep everything the night before.
Slice the vegetables and store them in the fridge. Season the pork and wrap it tightly. In the morning, just assemble everything in the slow cooker.
Recipe Instructions
Step 1: Season the Pork
Pat the 2 lb pork tenderloin dry with paper towels. Rub it evenly with 1 teaspoon salt, ½ teaspoon black pepper, 1 teaspoon garlic powder, and 1 teaspoon dried thyme.
Step 2: Sear the Pork
Heat 1 tablespoon olive oil in a skillet over medium-high heat. Place the seasoned pork tenderloin into the hot pan and sear for 2–3 minutes per side until browned.
Step 3: Prepare the Vegetables
Cut 2 cups diced potatoes, 1½ cups diced carrots, and 1 chopped onion. Mince 3 garlic cloves.
Step 4: Load the Slow Cooker
Place 2 cups diced potatoes, 1½ cups diced carrots, 1 chopped onion, and 3 cloves minced garlic into the black oval crockpot. Lay the seared pork tenderloin on top. Pour 1 cup chicken broth and 1 tablespoon Worcestershire sauce over everything.
Step 5: Slow Cook
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the pork is tender and the vegetables are soft. Slice the pork before serving.

Why This Recipe Works (Quick Science)
Slow cooking works because low heat breaks down connective tissue in the meat over time. Pork tenderloin stays moist while collagen slowly softens.
Root vegetables like potatoes and carrots contain starch that absorbs the cooking liquid. That’s why they end up tasting rich and savory instead of bland.
Searing the pork first creates browning through the Maillard reaction, which builds deeper flavor before slow cooking begins.
Common Mistakes
Skipping the sear
You’ll lose a lot of flavor if you skip this step.
Overcooking the pork
Tenderloin is lean and can dry out if cooked too long.
Cutting vegetables too small
Small pieces can turn mushy in a slow cooker.
Not seasoning enough
Slow cooker meals need good seasoning at the start.
What to Serve With
This dish is already hearty, but it pairs well with:
- Buttery dinner rolls
- Simple green salad
- Steamed green beans
- Roasted Brussels sprouts
- Applesauce on the side
Leftovers and Storage
Store leftovers in an airtight container in the fridge for 3–4 days.
To reheat:
Warm in the microwave or on the stove with a splash of broth.
To freeze:
Freeze pork and vegetables together for up to 2 months.
