Slow Cooker Pork Loin with Maple Glaze will become a family favorite and a go-to recipe to double and freeze for a perfect make-ahead freezer meal! It’s so easy to make. In fact there are only 3 main steps to this recipe:

  1. Marinate the pork loin.
  2. Cook it in the slow cooker.
  3. Thicken the sauce for the maple glaze.

Before we break down these steps, it’s first important to understand the cut of meat we’re using in this recipe.

What Is a Pork Loin?

Pork loins are a wider cut and are usually covered with a thicker fat cap. They do much better in the crock pot and even in the Instant Pot than a leaner cut like a pork tenderloin.

There is a lot of confusion when it comes to pork loins vs pork tenderloins.

Pork loin and pork tenderloin are not cut from the same part of the animal, and in fact, look really different — pork tenderloin is thin and small, while a pork loin is wide enough that you can cut steak-like pieces from it. How you cook it, though, is the main difference. Pork tenderloin is best quickly cooked over fairly high heat, while pork loin lends itself well to slow-roasting or grilling methods.

The Kitchn

As a side note: While we love pork tenderloin recipes, they don’t work great in the Crock Pot. They dry out fast and, while testing pork recipes for our cookbook, we found that baking or grilling pork tenderloin is the preferred cooking method.

Step-by-Step Instructions

Step 1: Season and Marinate the Pork Loin

A pork loin cut is pretty bland on its own. It needs some flavor pumped into it which is why we recommend seasoning and marinating it before slow cooking it. Here are the ingredients you’ll need on hand for the marinade.

  • Onion
  • Garlic cloves
  • Aavocado oil or olive oil
  • Soy sauce (For gluten-free sub GF Tamari Soy Sauce or Coconut Aminos)
  • Maple syrup
  • Fresh ginger

Add all of these and the pork loin into a freezer bag. Marinate the pork loin for at least 2 hours. The longer the better though! This is why we love making this one a freezer meal. More on that below though!

Step 2: Cook in the Slow Cooker

Time to cook your marinated pork.

After testing hundreds of recipes over the years, we have narrowed down the perfect cooking times for slow cooker recipes. In fact, we have put them all in 1 easy printable cheat sheet for you below!

When it comes to cooking a pork loin in the slow cooker, you’ll find that many reputable sites have you cooking it longer than we advise. Similar to cooking chicken in the slow cooker, SO many reputable sources have you overcooking it!

Using our digital meat thermometers as our guide, we have found that pork loin only needs to cook in the slow cooker for 3-4 hours. Because it can dry out so fast, be sure to check the internal temperature.

Step 3: Make the Maple Glaze

What makes our pork loin recipe stand out among others is this delicious maple glaze that you will serve over the cooked pork. Don’t skip this step!

Carefully pour or ladle the juices from the slow cooker into a medium saucepan. In a small bowl, stir together the cornstarch and water until smooth. Add the cornstarch mixture (this is called a slurry) to the pan and bring to a boil over high heat. Reduce the heat to maintain a simmer and cook, whisking, until thickened, about 3 minutes. Remove from the heat. Taste and season with salt and black pepper, if desired.

Description

The combination of maple syrup, soy sauce, and fresh ginger in this slow cooker pork loin recipe creates a delicious sweet-savory combo.


Ingredients

  • 1/2 onion, diced
  • 2 garlic cloves, minced
  • 1 tablespoon avocado oil or olive oil
  • 1 (3 pound) boneless pork loin roast, trimmed of excess fat
  • 1/3 cup low-sodium soy sauce (For GF: Use gluten-free Tamari Soy Sauce or Coconut Aminos)
  • 2/3 cup pure maple syrup (do not use fake pancake syrup)
  • 1 tablespoon minced or grated fresh ginger
  • 1/8 teaspoon cayenne pepper (or a pinch of red pepper flakes)
  • 2 tablespoons cornstarch

Instructions

Make It Now:

  1. Stir together the diced onion, minced garlic, and oil in a microwave safe bowl. Cover with a paper towel (to prevent splatters) and microwave until softened, about 5 minutes. (Alternatively, you can saute them in a pan over medium-high heat, adding the garlic during the last minute of cooking time.) 
  2. Pat the pork dry with paper towels, season it lightly on all sides with salt and black pepper. 
  3. Place the pork loin, soy sauce, maple syrup, ginger, cayenne, and cooked onion mixture in a gallon-size freezer bag. Seal tightly and toss to combine. (Freezing instructions begin here.)
  4. Marinate the pork in the refrigerator for at least 2 hours and up to 24 hours.
  5. Transfer the pork and marinade to the slow cooker. Cover and cook for 3-4 hours on low, or until the pork registers 145°F internally. Transfer the pork to a cutting board, tent with foil, and let rest for about 10 minutes.
  6. Carefully pour or ladle the juices from the slow cooker into a medium saucepan. In a small bowl, stir together the cornstarch and 2 tablespoons of water until smooth. Add the cornstarch mixture to the pan and bring to a boil over high heat. Reduce the heat to maintain a simmer and cook, whisking, until thickened, about 3 minutes. Remove from the heat. Taste and season with salt and black pepper, if desired. 
  7. Cut the pork into 1 ⁄2-inch thick slices. Fan them out on a serving platter and drizzle the sauce over the meat. Serve.

Freeze For Later: Follow Steps 1 through 3. Freeze.

Prepare From Frozen: Note: You will need to have cornstarch, salt, and pepper on hand to complete this meal. Thaw the meal completely using one of these safe methods. Follow Steps 5 through 7.


Notes

Gluten-Free Version: Use gluten-free Tamari soy sauce or coconut aminos instead of soy sauce. 

Since a pork loin roast can easily dry out, make sure to take an internal temperature and stop cooking it when it reaches 140-145°F. It will still be slightly pink on the inside when done.

Tip: Fresh ginger stores well in the freezer for a long time. Peel and tightly wrap the leftover ginger in plastic wrap or place a freezer bag. Freeze and use for future recipes.
