Slow Cooker French Onion Soup

Slow Cooker French Onion Soup
A super easy way to make french onion soup that tastes like you slaved over the stove for hours!


 I love french onion soup, but it takes too much time to caramelize the onions for me to make it on a week night. That was the case until I tried making it in the slow cooker. The onions caramelize perfectly while I am at work and when I get home I just have to heat the broth and melt cheese on the bread. I think this is the only way I will make French Onion Soup from now on!
3 large onions(or 6-8 small)
3 tablespoon olive oil
1 teaspoon sugar
1/4 teaspoon black pepper
4 cups beef broth
1/2 cup red wine
4 slices French bread, 1 inch thick
4 oz Gruyere cheese

Slice onions as thin as you can. The thinner they are, the softer they will get as they caramelize all day.
Place onions, olive oil, sugar, and pepper in a slow cooker. Cover and cook on low for 8-10 hours until nice and caramelized.

Add broth and wine. Cover, turn to high, and cook for 30 minutes until heated through.
Before serving, cut French bread or baguette into slices. Fill oven safe soup bowls to the top, then cover with slice of bread and a slice of cheese. Set under the broiler for 2-3 minutes, or until cheese is bubbly and golden brown. Be careful when serving as bowls will be hot!
