🛒 What You’ll Need

Before we start cooking, gather these ingredients:

For the Roast:

  • 3–4 lb pork loin roast

  • 2–3 apples (such as Granny Smith or Honeycrisp), cored and sliced

  • 1 large onion, thinly sliced

  • 1–2 cloves garlic, minced

  • 1 cup apple juice or apple cider

  • 1 tbsp cinnamon

  • 2 tbsp brown sugar

  • 1 tsp salt

  • ½ tsp black pepper

  • 1 tbsp Dijon mustard

  • Optional: fresh thyme or rosemary

For the Sauce:

  • 2 tbsp cornstarch

  • 3 tbsp cold water


👩‍🍳 Step-by-Step Instructions

🔥 Step 1: Prepare the Pork

Take your pork loin out of the fridge and pat it dry with paper towels. This helps the seasonings stick better.

Season the roast generously with salt and pepper on all sides.

🍎 Step 2: Layer the Slow Cooker

In the bottom of your slow cooker, spread the sliced onions and apples evenly. These will act as a fragrant bed for your pork and help infuse it with flavor.

Sprinkle the minced garlic over the apples and onions.

🧂 Step 3: Season and Combine

In a bowl, mix together:

  • Cinnamon

  • Brown sugar

  • Dijon mustard

  • Apple juice (or cider)

Pour this mixture over the pork loin, making sure it’s well coated. The cinnamon and apples will create a sweet aroma that blends perfectly with the pork.

Place the seasoned pork on top of the apples and onions.

⏱ Step 4: Slow Cook

Cover your slow cooker and set it to LOW for 6–8 hours, or HIGH for 3–4 hours.

You’ll know it’s done when the pork is:
✔ Tender and easily pulls apart
✔ Golden-brown on top
✔ Smelling like heaven

🥣 Step 5: Make the Sauce

Once the pork is cooked, carefully lift it out and set it aside on a cutting board.

Strain the liquid from the slow cooker into a saucepan. In a small bowl, whisk the cornstarch with cold water until smooth. Add this slurry to the saucepan and heat over medium heat, stirring constantly until the sauce thickens.

Pour the sauce over your sliced pork for a rich, glossy finish.
