Slow cooker apple pie filling recipe

Ingredients

• 8 medium firm apples (about 3 lb), peeled, cored and sliced ½ inch thick
• ½ cup packed brown sugar
• ¼ cup granulated sugar
• 2 tbsp lemon juice
• 1½ tsp ground cinnamon
• ¼ tsp ground nutmeg
• Pinch of salt
• 2 tbsp butter, cut into pieces
• To thicken: 3 tbsp cornstarch mixed with 3 tbsp cold water

Equipment

A 4 to 6-quart slow cooker. Apples shrink a lot as they cook, so a full cooker at the start is fine.

Steps

1. Toss. Put the apples in the slow cooker with the lemon juice and stir to coat.
2. Season. Add both sugars, cinnamon, nutmeg and salt, and stir. Dot the butter on top.
3. Cook. Cover and cook on LOW for 3 to 4 hours or HIGH for about 2 hours. Stir once halfway. The apples should be tender but not falling apart.
4. Thicken. Stir the cornstarch and cold water together until smooth. Stir it into the apples.
5. Finish. Cook on HIGH, uncovered or with the lid ajar, for 20 to 30 minutes, until the juices turn glossy and thick.
6. Cool. Let the filling cool completely before using it in a pie, or chill it in shallow containers.

Best apples for apple pie filling

A mix of tart and sweet apples gives the best flavor. Half Granny Smith and half Honeycrisp is a good place to start.

Tips for perfect filling

• Avoid mushy apples: cut thicker slices and check from 3 hours on LOW. Cooking all day turns the apples to sauce.
• Too runny: stir in another tablespoon of cornstarch slurry and cook 15 minutes more.
• Too thick: stir in a splash of apple juice or water.
• More flavor: add a pinch of allspice or cloves, or a splash of vanilla at the end.

Healthier slow cooker apple pie filling

Sweet apples need less sugar. Use Honeycrisp or Jonagold, cut the sugar to ¼ cup in total, and add extra cinnamon. You can also swap the sugar for 3 to 4 tablespoons of maple syrup.

Skip the butter for a lighter version. The filling will be a little less glossy but still tasty.
