Cut onions in half and slice thinly. Place them in the crock pot.
3 pounds Yellow Onions
Thoroughly stir melted butter into the onions to ensure they are fully coated.
1/2 cup Butter
Set the crock pot to low and cook overnight for 10-12 hours.
Add minced garlic to the cooked onions in the morning.
2 cloves Garlic
Stir sherry into the onion mixture, scraping the bottom of the crock pot to mix in any browned bits.
1/2 cup Dry Sherry
Tie the bay leaf and thyme sprigs together with kitchen twine and add them, along with salt, pepper, and broth, to the crock pot. Stir well.
8 cups Beef Broth, 1 Bay Leaf, 2 sprigs Fresh Thyme, Salt & Pepper
Cook on low for 8-10 hours or on high for 4-6 hours until flavors are well combined.
Preheat the oven to 400°F and position the rack in the middle.
Slice the French bread into 1/2" thick slices and lightly brush both sides with olive oil.
1 loaf French Bread, Olive Oil
Arrange the bread slices on a baking sheet and bake for 8 minutes on the first side, then 2 minutes on the second side, until golden brown.
Switch the oven to broil.
Pour the soup into bowls, filling them 3/4 full. Make sure you are using oven-safe bowls. Divide half of the shredded Gruyere cheese among the bowls.

Place the baked bread on top of each bowl and sprinkle with the remaining cheese.
Broil the topped soups on the middle rack for 2-3 minutes or until the cheese is lightly browned and bubbly.
