This Slow Cooker French Onion soup is a classic! Ample flavor and cheese—you won't regret whipping this up.


• 4 yellow onions, skins removed and thinly sliced into rings • 4 tablespoons butter • 2 tablespoons minced garlic • 8 cups beef broth • 1 bay leaf • 6 slices crusty french bread • 8-12 slices gruyere or swiss cheese


Step 1

Add butter and onion rings to the largest pan/skillet you have and saute over medium-high heat until onions are translucent and start to brown (about 10 minutes). Cover and cook an additional 5 minutes longer to let them caramelize.

Step 2

Transfer onions to the slow cooker. Add garlic, broth, and the bay leaf. Cover and cook on high 3-4 hours or on low 6-8 hours (or up to 10).

Step 3

30 minutes before serving, preheat the oven to 420 degrees.

Step 4

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. Set aside.

Step 5

Set 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. Serve with crusty bread and garnish with parsley, if desired.
