Do you love caramelized onions as much as I do?  They have such a wonderful flavor.  It’s a sweet and savory flavor all at the same time and it tastes wonderful in so many different dishes.

The problem with caramelized onions, though, is that they take a long time to properly make.  And not only do they take a long time, it’s mostly hands on time.  They require almost constant stirring so that they don’t burn.

But don’t worry, I have a solution for you that makes caramelized onions easy peasy.  You can easily make them in your Instant Pot or your slow cooker.  Other than slicing the onions, either appliance will do all of the work for you.  This makes it so easy to have caramelized onions on hand at all times.  And the other great thing is that they freeze beautifully.

If you already have caramelized onions on hand, these French onion cheese toasts are a quick and easy appetizer that comes together in no time.  They are also soooo delicious.  They’re especially perfect for holiday entertaining.

The rest of the ingredients for these cheese toasts are pretty simple and easy to have on hand.  All you need is a baguette, shredded cheese, garlic and fresh or dried thyme.
