Follow these instructions to create your Crockpot Apple Crisp:

1. Prepare the Apples: Peel, core, and slice the apples evenly. Place them in a large mixing bowl.
2. Add Lemon Juice: Drizzle the lemon juice over the apples and toss gently. This will prevent browning and add flavor.
3. Mix Sugar and Spices: In another bowl, combine granulated sugar, cinnamon, and nutmeg. Stir the mixture until well blended.
4. Combine: Sprinkle the sugar mixture over the apples and toss to coat evenly. Pour the apple mixture into the bottom of your crockpot.
5. Prepare the Topping: In a separate bowl, combine the rolled oats, flour, brown sugar, and salt. Add the cubed butter.
6. Mix Topping: Using a fork or pastry cutter, mix until crumbly and well combined. The mixture should resemble coarse crumbs.
7. Layer the Topping: Evenly spread the topping mixture over the apple filling in the crockpot.
8. Cover and Cook: Place the lid on your crockpot and cook on high for 3 to 4 hours or low for 6 to 8 hours.
9. Check for Doneness: The apple crisp is done when the apples are tender, and the topping is golden brown.
10. Serve Warm: Once cooked, remove the lid and let it cool for a few minutes before serving.
