One of the benefits of making your dips and side dishes in a slow cooker is that you can make them ahead of time and simply warm them up before guests arrive.
You can make a spinach artichoke dip, a sweet creamed corn recipe, or try a buffalo chicken dip. You just need to put the ingredients together and let the slow cooker do the work.
If you are unsure about how much you should make, a good rule of thumb is to use a 3 or 5-quart slow cooker for up to 4 people or a 6-quart size for a larger gathering.
