Crockpot liners are designed to make cleanup easy and prevent sticking, but there are a few other options that work just as well. If you don't have any crockpot liners on hand, try one of these methods:
1. Aluminum foil. Cut a piece of aluminum foil to fit inside your crockpot, making sure it comes up the sides a bit. Spray the foil with cooking spray and then add your ingredients as usual. When you're done cooking, let the crockpot cool slightly before removing the foil (it will be hot!) and then washing out the pot as normal.
2. parchment paper. Parchment paper is great for preventing sticking and making cleanup a breeze. Simply line your crockpot with a sheet of parchment paper before adding your ingredients. When you're done cooking, simply remove the parchment paper and throw it away - no scrubbing required!
3. Slow cooker bags. These specialized bags are made specifically for slow cookers and can be found at most grocery stores in the kitchenware aisle. To use, simply place your ingredients in the bag and then place it in the crockpot - no need to spray with cooking spray first. When you're done cooking, remove the bag from the pot and dispose of it - again, no scrubbing necessary!
