Ingredients
Method
- Prep the vegetables. Place potatoes, carrots, onion, and garlic in the bottom of the slow cooker. Sprinkle with a pinch of salt and pepper.
- Mix the seasoning blend. In a small bowl, combine salt, black pepper, garlic powder, onion powder, thyme, and smoked paprika.
- Season the pork. Pat the tenderloins dry with paper towels. Rub the seasoning blend all over the pork, pressing gently so it adheres.
- Sear the pork (recommended). Heat olive oil in a large skillet over medium-high heat. Sear the tenderloins for 1–2 minutes per side until browned. This step adds flavor and color.
- Make the cooking liquid. In a measuring cup, whisk together broth, soy sauce, Dijon, Worcestershire, and honey.
- Load the slow cooker. Place the seared tenderloins on top of the vegetables. Pour the broth mixture around (not directly over) the pork to keep the seasoning in place.
- Cook low and slow. Cover and cook on LOW for 3 to 4 hours, or until the pork reaches an internal temperature of 145°F at the thickest point. Avoid overcooking; tenderloin is lean and cooks faster than roasts.
- Rest and finish. Transfer pork to a cutting board, tent with foil, and rest for 5–10 minutes. Stir butter into the vegetables and juices in the slow cooker for a silky finish.
- Optional: Thicken the sauce. If you want a gravy, whisk the cornstarch and water in a small bowl. Stir into the slow cooker, cover, and cook on HIGH for 10–15 minutes until slightly thickened.
- Slice and serve. Slice pork into medallions across the grain. Spoon vegetables and sauce onto plates, top with pork, and garnish with parsley.
Why This Recipe Works
This recipe uses a pork tenderloin, which cooks quickly and stays lean and tender when handled correctly. A quick sear locks in color and flavor, giving you a better crust and deeper taste.
Root vegetables like carrots and potatoes hold up to long, slow heat and soak up all the savory juices.
The simple seasoning blend and broth create a ready-made sauce without extra steps. Best of all, it’s mostly hands-off, freeing you up for everything else on your plate.
Ingredients
- 2 pork tenderloins (about 1 to 1.25 pounds each), silver skin trimmed
- 1 tablespoon olive oil (for searing)
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme (or Italian seasoning)
- 1/2 teaspoon smoked paprika (optional, for a deeper flavor)
- 1 pound baby potatoes, halved (or 4 medium potatoes, cut into chunks)
- 4 carrots, peeled and cut into 1-inch pieces
- 1 yellow onion, sliced into thick wedges
- 3 cloves garlic, smashed
- 1 cup low-sodium chicken broth (or beef broth for a richer sauce)
- 2 tablespoons soy sauce (or coconut aminos)
- 1 tablespoon Dijon mustard
- 1 tablespoon Worcestershire sauce
- 1 tablespoon honey (or brown sugar)
- 2 tablespoons unsalted butter (for finishing, optional)
- Fresh parsley, chopped, for garnish (optional)
- 1 tablespoon cornstarch + 1 tablespoon water (optional, for thickening sauce)

Storage Instructions
- Refrigerate: Store leftovers in an airtight container with some sauce to keep the pork moist. Keeps 3–4 days.
- Freeze: Freeze sliced pork and vegetables in freezer-safe containers with sauce for up to 3 months.
Thaw overnight in the fridge.
- Reheat: Warm gently on the stovetop or in the microwave with extra broth or sauce, just until heated through. Avoid overcooking to keep the pork tender.
Benefits of This Recipe
- Hands-off cooking: After a quick sear, the slow cooker does the work.
- Balanced meal: Protein, starch, and veggies all in one pot.
- Lean and tender: Pork tenderloin is naturally lean but still juicy when cooked to 145°F.
- Make-ahead friendly: Easy to prep in the morning and finish at dinnertime.
- Customizable: Swap veggies, tweak seasonings, or make a quick gravy—your call.
What Not to Do
- Don’t overcook the pork. Tenderloin dries out past 145°F. Use an instant-read thermometer for accuracy.
- Don’t skip seasoning. This cut is mild; it needs salt, aromatics, and acidity to shine.
- Don’t pile liquids over the pork. Pour broth around the sides so the crust and spices stay put.
- Don’t cut vegetables too small. They’ll turn mushy.
Keep chunks around 1 inch.
- Don’t cook on HIGH the whole time. HIGH risks dry pork. LOW yields better texture.
Alternatives
- Different vegetables: Try parsnips, sweet potatoes, celery, or mushrooms. Add delicate veggies like green beans in the last hour.
- Flavor twists: Use rosemary and lemon zest for a bright herb profile, or add chili flakes and cumin for a subtle kick.
- Sauce variations: Swap Dijon for whole-grain mustard, use maple instead of honey, or add a splash of balsamic for tang.
- No sear option: If you’re short on time, skip searing.
Increase smoked paprika slightly and don’t skip the rest period.
- Gluten-free: Use gluten-free Worcestershire or omit it; soy sauce can be swapped with tamari or coconut aminos.
- Single tenderloin: Halve the seasoning and reduce the cook time. Start checking temperature around 2.5 hours on LOW.
FAQ
Can I use pork loin instead of pork tenderloin?
Yes, but the cook time changes. Pork loin is larger and denser, so it needs a longer cook—usually 5–6 hours on LOW for a 2–3 pound loin.
Keep an eye on temperature and aim for 145°F, then rest before slicing.
Do I have to sear the pork first?
No, but it improves flavor and appearance. Searing builds a browned crust that adds depth. If you skip it, increase seasoning slightly and consider broiling the sliced pork briefly before serving to add color.
How do I prevent the vegetables from getting mushy?
Cut them into larger chunks and place them on the bottom, where they’ll cook in the juices.
Avoid overcooking and stick to the LOW setting. If using softer vegetables, add them during the last hour.
What’s the best way to check doneness?
Use an instant-read thermometer inserted into the thickest part of the tenderloin. Pull at 145°F.
The pork may have a slight blush in the center, which is safe and keeps it juicy.
Can I make this without honey or sugar?
Yes. The sweet element balances the savory components but isn’t required. Omit it or replace it with a splash of apple juice, maple syrup, or a pinch of brown sugar if you want subtle sweetness.
How can I make the sauce creamier?
After cooking, stir in a splash of heavy cream or a dollop of sour cream.
Warm gently to avoid splitting. Taste and adjust salt before serving.
What if my slow cooker runs hot?
Check early. Start checking temperature at the 2.5–3 hour mark on LOW.
Each appliance varies, so once you learn your cooker’s quirks, you can adjust accordingly.
Can I add apples?
Absolutely. Slice two firm apples and add them in the last 60–90 minutes. They bring a nice sweetness that pairs beautifully with pork.
