Easy Pork Loin Crock Pot Recipe (with Secret Sauce!)

This pork loin crock pot recipe is 33g of protein per serving, barely 2 minutes of prep, and a pan sauce built right into the crockpot using cold butter and a cornflour slurry. Super easy – no extra pans, and no separate gravy step. If you want other macro-friendly recipes like my pork loin crock pot, this Healthy Chicken Lasagna is worth a look.

Why you’ll love this recipe

• Great flavor: Soy sauce, Worcestershire, honey, and fresh rosemary together make this pork loin crock pot recipe taste quite complex, not super sweet and one-note like a lot of slow cooker recipes out there. My Soy Garlic Chicken Breast has a similar sweet & savory vibe, and this crock pot pork loin is just as good.
• So easy: Tip everything in, set it, walk away. My slow cooker pork loin genuinely couldn’t be simpler, quite similar to this Easy Braising Steak With Gravy.
• Works any which way: Sliced with mash, shredded into wraps, packed for meal prep… crockpot pork loin works however you need it to!
• 33g protein & 313 kcal: Honestly one of the best macros you’ll get from a slow cooker meal. It’s great for meal prep and genuinely filling too!

Ingredients

A few things make this pork loin crock pot recipe worth paying attention to:

• Pork tenderloin: I specifically use a 460g tenderloin here, and the distinction really does matter. It’s a much smaller, leaner cut than a full pork loin and dries out faster, so the timings in most crockpot pork loin guides won’t work the same way. Get this right and you’re already ahead of most recipes out there honestly.
• Fresh rosemary: Whole sprigs go in during the cook and leave behind this subtle, piney warmth you just can’t get from a jar of dried herbs. Fresh thyme works if that’s what you’ve got, and I use it in my Lemon and Thyme Chicken Thigh Tray Bake as well. It’s really simple fresh ingredients like this that set the best crock pot pork loin recipes apart from the rest.
• Cold butter: Cold butter cubed into the hot liquid emulsifies into something nice and glossy as the temperature difference lets it incorporate slowly rather than just splitting. Add the cornflour slurry and you’ve got the perfect sauce, right there in the pot. I use a similar trick in my Easy Chicken Piccata.

Variations/ Adaptations

You can definitely play around with this pork loin crock pot recipe:

• Make it sweeter: Swap the honey for maple syrup and you’ll get a slightly caramelized edge that works SO well with the soy and Worcestershire. It’s really good with slow cooker pork loin recipes generally.
• Add veggies: Chuck halved baby potatoes (if you’ve got extra from making Crispy Air Fryer Baby Potatoes) or thick carrot chunks underneath the meat before you start. They soak up all the broth as the pork loin in slow cooker cooks.
• Make it gluten-free: Swap soy for tamari and double-check your Worcestershire label. The cornflour slurry is already gluten-free, so that’s genuinely all you need to adapt this crock pot pork loin recipe.

How to make this Pork Loin Crock Pot recipe

Step 1: Combine the chicken stock, soy sauce, honey, Worcestershire sauce, and seasonings in your crockpot. Add the raw pork tenderloin and fresh rosemary sprigs, turning the meat with tongs to coat it well.

Step 2: Cook on high for 3 hours or on low for 6-7 hours. The pork is perfectly cooked when it reaches an internal temperature of 145°F (62°C).

Step 3: Remove the cooked pork to a resting board, discard the rosemary, and turn the crockpot heat to high. Whisk in the cold butter cubes and cornflour slurry, heating until the butter emulsifies and the sauce thickens.

Step 4: Let the pork rest for 5 to 10 minutes before slicing it into even rounds. Return the sliced pork to the crockpot to coat it in the rich, glossy pan sauce before serving.

Serving Suggestions

Leftover Storage and Reheat Instructions

Store the slices in the sauce and this pork loin crock pot recipe keeps brilliantly! That’s actually what makes it better than your average crockpot pork loin recipe for meal prep, the sauce keeps the meat from drying out completely.

Refrigerator: Cool fully before going into an airtight container. It’s good for up to 4 days.

Freezer: Slice, submerge it in sauce, freeze in a freezer-safe container for up to 3 months.

Reheat: Low and slow in a saucepan, or microwave in 30-second bursts. If it’s thickened up in the fridge, a tiny splash of water sorts it.
