Slow cooker french onion soup – loads of flavor, caramelized onions, and CHEESE!
You see all that cheese? It’s ooey-gooey-melty-stretchy-awesomeness and I’m in love with it.
Allllllll thaaaaaat CHEEEEEESE.
Step by Step Directions
Add butter and onion rings to the largest pan/skillet you have and saute over medium-high heat for about 10 minutes or until onions are translucent and start to brown.
Cover and cook about 5 minutes longer to let them caramelize a little more.
Transfer onions to slow cooker. Add garlic, broth, and bay leaf.
Cover and cook on high 3-4 hours or on low 6-8 hours (or up to 10).
About 20-30 minutes before serving, preheat oven to 420 degrees.
Place slices of bread in a single layer on a baking sheet.
Place in preheated oven for about 5 minutes, then flip the bread slices over and return to oven for another 5 minutes or so until bread is dried and crunchy.
Place oven-safe bowls on the baking sheet.
Fill each with soup from the slow cooker.
Place 2 slices of swiss cheese (overlapping) on top of the soup so the edges are hanging over the sides of the bowls.
Bake about 10 minutes until cheese is melty.
