Step-by-Step Slow Cooker Instructions
Get ready for the easiest apple crisp you’ve ever made.
Part 1: Prepare the Filling and Topping
- Prep the Slow Cooker: Lightly grease the inside of your slow cooker crock with coconut oil or cooking spray.
- Mix the Apple Filling: In a large bowl, combine the sliced apples, 2 tablespoons of maple syrup, the lemon juice, 1 teaspoon of cinnamon, and the cornstarch. Toss everything together until the apples are evenly coated.
- Arrange in Slow Cooker: Pour the apple mixture into the prepared slow cooker and spread it out in an even layer.
- Mix the Crumble Topping: In a separate medium bowl, stir together the rolled oats, almond flour, 1 teaspoon of cinnamon, and salt. Pour in the 3 tablespoons of maple syrup and the melted coconut oil. Mix with a fork until the dry ingredients are moistened and a crumbly texture forms.
Part 2: Cook and Serve
- Add the Topping: Sprinkle the prepared crumble topping evenly over the apples in the slow cooker.
- The Paper Towel Trick: To prevent the topping from getting soggy from condensation, lay a clean dish towel or a double layer of paper towels over the top of the slow cooker opening before placing the lid on securely.
- Cook: Cook on LOW for 4 hours or on HIGH for 2 hours, until the apples are tender and the topping is cooked through.
- Serve Warm: Let the apple crisp cool for a few minutes with the lid off. Serve warm, on its own or with a scoop of vanilla yogurt or ice cream for a delicious treat.
Tips for the Perfect Slow Cooker Crisp
- The Towel is Key: Don’t skip the paper towel or dish towel trick! It’s essential for absorbing moisture and helping the crumble topping get firm and crisp rather than soft and steamy.
- Choose the Right Apples: Use firm baking apples that will hold their shape during the long cooking time. Honeycrisp, Granny Smith, Braeburn, and Gala are all excellent choices.
- No Peeking! Every time you lift the lid, you release heat and moisture, which can affect the cooking time and the texture of the topping. Let the slow cooker work its magic undisturbed.
- Storage: Store any leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave for a quick and cozy snack.
