Directions
- 1
To the bowl of your crockpot, add the butter, onions, garlic, brown sugar and worcestershire sauce. Stir everything together, cover the crockpot and cook on low for at least 8 hours or up to 14 hours. I like cooking the onions overnight while I sleep (note that I have noticed that all crockpots cook differently, if yours seems to cook fast, check the onions at 8 hours in to make sure nothing is burning).

The next morning, stir the flour into the onions and then add the beer (or wine), beef broth, bay leaves, thyme and a good pinch of pepper. Cover and cook on low for 6-8 hours or on high for 3-4 hours. The longer and slower you can cook this the better. Taste and season with salt + pepper if needed.

Just before you're ready to eat, make the french toast. In a shallow bowl, whisk together the eggs, milk, parmesan and a pinch of salt + pepper.

Preheat the broiler to high.

Heat a large skillet over medium heat and add the butter to melt.

Submerge one piece of toast at a time into the egg mixture, allowing it to sit 30 seconds in the eggs. Remove and allow the excess to drip off back into the bowl. Place the toast on the hot skillet and cook until golden brown, about 3 minutes per side. Repeat with the remaining bread.

Ladle the french onion soup into oven safe ramekins or bowls. Place 1-2 pieces of toast on top of the soup and cover with cheese. Place the ramekins on a baking sheet and place under the broiler for 30 seconds to 1 minute, or until the cheese is melted. WATCH close, the broiler works quick!

Serve the soup with fresh thyme and enjoy hot, right out of the oven!
To make this soup on the stove
- 1
Heat a large heavy bottomed soup pot over medium-high heat and add the butter. Add the onions + brown sugar and cook about 10 minutes, stirring frequently, until softened. Add the worcestershire sauce and let it cook into the onions. Continue to slowly cook the onions until they are golden brown and caramelized, about 10-15 minutes.
- 2
Once the onions have caramelized, add the garlic and cook 30 seconds, then stir the flour into the onions and add the beer (or wine), beef broth, bay leaves, thyme and a good pinch of pepper. Cover and cook over low heat for 30 minutes or until ready to serve. Taste and season with salt + pepper if needed. Continue with the french toast as directed above.

About this Recipe
Craving the deep, savory comfort of French onion soup but intimidated by the long simmering? This Crockpot French Onion Soup with Cheesy French Toast recipe makes it effortlessly delicious, allowing your slow cooker to do most of the work.
Why This Recipe Works
The genius of this recipe lies in its set-it-and-forget-it approach, transforming humble sweet onions into a rich, deeply caramelized base without constant stirring. Paired with hearty Cheesy French Toast, it elevates the classic soup experience into a truly satisfying main course. The combination of slow-cooked flavors and a cheesy, crisp topping is simply irresistible.
What to Expect
Prepare for a truly comforting and indulgent bowl. The soup itself is a symphony of flavors: sweet, tender onions melt into a savory beef broth, enhanced by the subtle tang of beer or red wine, and brightened by fresh thyme and bay. Each spoonful is robust and complex. Perched atop, the Cheesy French Toast offers a delightful contrast—crisp on the outside, soft within, and blanketed with melted Gruyere and Parmesan, adding a creamy, salty counterpoint to the rich soup. This is hearty, warming food that nourishes both body and soul.
Customization & Variations
While sweet onions are ideal for their caramelization, you can experiment with the type of beer or red wine you incorporate to adjust the soup's depth; a drier red wine or a richer stout will impart different characteristics. If you're looking to enhance the aromatic profile further, a pinch of freshly grated nutmeg can be a lovely addition at the end. For an extra layer of flavor on the French toast, consider a sprinkle of dried herbs like oregano or chives before grilling.
Serving & Context
This Crockpot French Onion Soup with Cheesy French Toast is a perfect cold-weather meal, ideal for a cozy weekend lunch or a comforting weeknight dinner. Serve it directly from the crockpot for ease, with each bowl topped generously with a slice or two of the cheesy bread, allowing it to soak up the glorious broth.
