The pork is quickly seared until golden brown with onions to add flavor and added to the crock pot with carrots (you can pop in potatoes to make it a full meal!). It comes out incredibly tender, juicy, and full of flavor. The savory sauce made from the cooking juices takes it over the top.

It’s one of those set it and forget it meals that’s perfect for busy weeknights, Sunday dinners, or when you just want something hearty without a lot of effort. Pair it with mashed potatoes, rice, or crusty bread and dinner is done!

How To Make It

Start by adding the beef broth and carrots to the bottom of your crock pot. Season lightly with salt and pepper. If using potatoes, add them now. Be sure to dice them small so they cook completely.

Carrot sticks seasoned with black pepper are placed in a slow cooker with a small amount of liquid at the bottom, ready for cooking.

In a small bowl, mix together the brown sugar, salt, pepper, mustard powder, and smoked paprika.

Pat the pork tenderloins dry with paper towels and rub the seasoning mixture all over the pork.

Two pieces of seasoned pork tenderloin are being seared in a black skillet, with a wooden spatula resting on the edge of the pan. The meat is lightly browned and sizzling in oil.

Heat the olive oil in a large skillet over medium-high heat. Add the sliced onions and sauté until they start to soften and get a little color, about 4–5 minutes. Transfer the onions to the crock pot.

Sliced onions and carrots are placed in a white slow cooker with broth, ready for cooking, on a light wooden surface.

Using the same skillet, sear the pork tenderloins for about 2 minutes per side until nicely browned. This step adds a lot of flavor.

Place the pork tenderloins in the crock pot on top of the carrots and onions.

Two seasoned pork tenderloins sit on top of sliced onions and vegetables inside a white slow cooker, ready to be cooked.

Cook on LOW for 2½–3½ hours or HIGH for 1½–2 hours, until the pork reaches an internal temperature of 145°F.

Let the pork rest for at least 10 minutes before slicing.

How To Make The Gravy

Strain the cooking juices from the crock pot into a saucepan over medium-high heat. If there isn’t enough liquid, add 1/2- 1 cup chicken or beef broth to the pan.

In a small bowl, whisk together the cornstarch and water to make a slurry.

Slowly pour the slurry into the saucepan while whisking. Continue whisking until the sauce thickens into a rich gravy. Add more seasonings/salt and pepper, to taste.

Pour the gravy over the sliced pork and enjoy!

Tips for the Best Pork Tenderloin

Don’t skip the sear. Browning the pork before slow cooking adds extra flavor.
Use a meat thermometer. Pork tenderloin is best at 145°F so it stays juicy. I love a heat-safe thermometer to ensure the pork doesn’t overcook and get dry.
Let it rest before slicing. This helps keep the juices inside the meat.

What to Serve with Crock Pot Pork Tenderloin

FAQ’s

Can I skip searing the pork?

Yes, but searing adds extra flavor and color. If you have time, it’s worth the extra step.

Can I add potatoes to the crock pot?

Yes! Baby potatoes or chopped Yukon gold potatoes work great alongside the carrots.

Can I use pork loin instead of pork tenderloin?

You can, but pork loin is larger and will need longer cooking time.

How do I store leftovers?

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently with a little broth to keep the pork moist. Freezer: Up to 3 months
