How To Make Old Fashioned Apple Crisp In The Crock Pot
Prepare the apples: Wash the apples under cold water. Then peel the skin with a sharp vegetable peeler. Core and use a sharp knife to cut into slices.
Season the apples: Add the apple slices to a mixing bowl, then sprinkle on the sugar, cinnamon, and nutmeg. Toss to coat, then add them to the bottom of your slow cooker.
Prepare the oat topping: Add the brown sugar and oats to a bowl along with the all-purpose flour and stir to combine. Add the cubed butter into the bowl and cut it into the mixture using a pastry cutter or two forks until damp crumbles are formed.
Assemble and slow cook: Spread the oat topping over the apples in the crockpot evenly. Cook on HIGH for 2 hours or until the apples are cooked through. Turn the slow cooker to warm, remove the lid and let it cool for 30 minutes before serving.
- The best types of apples to use for apple crisp are ones that are tart and sturdy such as Granny Smith apples. You can use any apples you enjoy, just beware that the taste and texture will vary.
- When making the oat crumble, make sure you start with very cold butter. If the butter melts, it will make the crumble too greasy.
- Cut all of the apple slices roughly the same size to ensure that they all finish cooking together at the same time.
- The amount of time it takes to cook this dessert depends on your individual slow cooker. Be sure to check the apples periodically after the first hour to ensure the proper cooking time.
- This slow cooker apple crumble will be extremely hot when it's finished cooking. Make sure you remove the lid to let it cool before serving.
- Give the topping a little extra crunch by adding chopped nuts such as pecans or walnuts.
- If you want a little extra sweetness, drizzle on some caramel sauce or chocolate chips before serving.
- For a fun twist, try using other fruits in season such as pears or berries.
- Use pumpkin pie spice to season the dish to add a little extra Fall flavor.
