Raw pork shoulder roast with labeled ingredients around it: honey, apple cider vinegar, olive oil, butter, garlic powder, cayenne, salt & pepper, thyme, smoked paprika, onion powder, whole garlic, and cornstarch.

Key Ingredients

Here’s a quick overview of the key ingredients for this recipe. For the full list of ingredients and exact measurements, be sure to check the recipe card at the bottom of this post.

Pork loin: Use a 4 to 5-pound roast with the excess fat trimmed off. Leaving just a little marbling helps keep the meat tender and gives the sauce something to cling to. Bring it to room temperature before searing so it browns more evenly. If you only have pork tenderloin, reduce the cooking time since it’s leaner.
Olive oil: Adds flavor and helps the spice rub stick. Avocado oil works as a substitute.
Smoked paprika: Brings a subtle smoky depth. Regular paprika works if that’s what you have.
Dried thyme: Earthy and aromatic. Italian seasoning can stand in if needed.
Garlic powder and onion powder: Pantry staples that build flavor without chopping.
Cayenne pepper (optional): Adds a gentle kick. Skip it if you’re cooking for kids.
Honey: The key to the sticky glaze. Maple syrup makes a nice variation.
Butter: Creates richness in the sauce. Use dairy-free butter if needed.
Garlic cloves: Fresh garlic adds a bold aroma as it cooks.
Apple cider vinegar: Balances the sweetness with tang. White wine vinegar or even balsamic can work in a pinch.
Cornstarch: Thickens the sauce. Arrowroot powder can be swapped in.

How To Make This Roast Pork Loin Crock Pot Recipe

Season the Pork & Sear

I start by rubbing the pork with just a touch of olive oil, then patting on my spice mix until every side is coated. The paprika and thyme smell amazing even before cooking.

Heat the remaining olive oil in a large skillet and sear the pork on all sides until golden brown. This step locks in flavor, and it only takes a few minutes. Be sure to watch the spices so they don’t burn.

Make Honey Butter Sauce

Once seared, transfer the pork to your slow cooker. In the same pan, melt the butter and sauté the garlic for about a minute.

Slow Cook & Rest Pork

When it’s fragrant, stir in honey, apple cider vinegar, salt, and pepper. Let it bubble for 30 seconds, then pour it over the pork in the slow cooker.

Cover and cook on LOW for about 5 hours, or until the pork is fork-tender. While it’s cooking, your kitchen will fill with the sweet, savory smell of garlic and honey.

Once done, transfer the pork to a platter and cover it with foil. I always let it rest for 15 minutes. It makes slicing much easier and keeps the meat juicy.

Thicken the Sauce & Serve

Pour the juices into a fat separator, then whisk the cooking liquid with a cornstarch slurry in a saucepan. Let it simmer until it thickens into a sticky glaze. This sauce is the star, so don’t skip this step!

Slice the pork into thick pieces and spoon that glossy sauce all over. I love serving this with mashed potatoes or roasted vegetables because the sauce ties everything together.

Do you have to brown pork before slow cooking?

I always do because it gives the pork so much more flavor, but you can skip it if you’re short on time.

Can I make this in the Instant Pot?

Yes. Sear the pork in the pot, add the sauce, then pressure cook on HIGH for about 40 minutes with a natural release.

Variations, Substitutions, and Recipe Tips

Make it Gluten-Free: Use arrowroot instead of cornstarch.

Make it Dairy-Free: Swap the butter for a plant-based option.

Spice it Up: Add red pepper flakes or extra cayenne for more heat.

Citrus Twist: Stir in a splash of orange juice or even a little orange zest for brightness.

Hosting Tip: Prep the sauce a day or two ahead and keep it in the fridge. On the day of your gathering, pour it into your crock pot.
