2 Great Reasons You Should Use a Slow Cooker for Soup

Buying a slow cooker was easily one of the best investments I’ve ever made for my kitchen. As a matter of fact, here are 2 great reasons why you should be using a slow cooker to make your paleo soups:

  • Perfectly tender ingredients. The process of slow cooking will end up producing perfectly tender cuts of meat and veggies when you’re making your soups (and stews too).
  • Brings out the flavors in a big way. Slow cooking your soups for lengthy periods of time really does go a long way towards bringing out more of the flavor in your ingredients. I’ve never had soups that are more flavorful than what my slow cooker can make!

How to Reheat Stuffed Pepper Soup

Many people think that leftover soup tastes even better after a day or two, especially if it’s reheated in a slow cooker. With that in mind, I would definitely recommend reheating this soup in your slow cooker as well.

If you’re in a hurry to reheat it though, you can just as easily microwave the soup or warm it up in a pot on your stove top.
