A modern-ish twist on a French classic, this completely vegetarian recipe can be made in a crockpot. Traditionally, French Onion Soup should have a slice of baguette with Gruyere Cheese melted over it, but I used my homemade sourdough bread instead. To make it vegan-friendly, substitute the cheese with soy cheese. If you’d like to make this in a crockpot, just toss all the ingredients together & cook on high for 1-2 hours. Reduce the heat to low & cook overnight. Ladle the soup into ramekins & bake as per instructions.
