Ingredients
- 3 pounds sweet onion Sliced into approximately 1/4" thick slices
- 1 tsp thyme dried leaves
- 3 Tablespoons butter melted
- 2 tsp brown sugar
- 1 tsp salt
- 1 tsp black pepper
- 1.5 cup Asiago cheese shredded
- 1 bay leaf
- 6 cups beef broth
- 1 Tbsp white wine dry
- 1 French baguette 12 oz, sliced approx 1 inch slices
Instructions
- Place the onions, butter and brown sugar in a large non-stick sauce pan.
- Stir together and cook over medium low heat until the onions are brown and caramelized (approximately 30-45 minutes). Stir frequently during this time so that the onions do not burn at the bottom of the pan.
- Once the onions are caramelized, place them in a 6 quarter slow cooker. Add the salt, pepper, thyme, bay leaf, beef broth and white wine to the crock pot as well.
- Cover and cook on low for 6-8 hours or on high for 3-4 hours.
- Meanwhile, slice the baguette into 1 inch thick slices. Bake the slice at 350 degrees F for 5-7 minutes to heat and brown slightly.
- Then spoon the soup into small oven safe bowls, top with the baguette (I did 2-3 slices per bowl) and then top with the approximately 1/4 cup of the shredded cheese.
- Place the bowls on a baking sheet and broil for 3-5 minutes until the cheese has melted and is slightly brown.Serve immediately while warm and enjoy!

Notes
- Slowly caramelize onions to develop sweetness and avoid bitterness, stirring frequently.
- Broil topped soup bowls just until cheese melts and browns slightly for best texture.
- Leftover soup can be stored airtight in the fridge up to 5 days.
- Use a good quality Asiago cheese for melting and flavor enhancement.
