By GratefulSea

Ingredients

• 4 large onions, sliced
• 2 Tablespoons butter
• 1 teaspoon sugar
• 2 quarts beef broth, no sodium added
• 1/4 cup sherry
• 2 sprigs fresh thyme
• 1-1/2 teaspoons salt
• Pepper to taste
• 1 cup croutons plain
• 8 ounces gruyere cheese, sliced (can substitute with swiss if needed)

Preparation

Step 1

Place onions, butter, sugar, and salt into the bottom of a 6-quart slow cooker. Cover and cook for 7 hours on high or until onions are soft and brown.

Add beef broth, sherry, thyme sprigs, and pepper to taste. Cover. Cook on high for another hour. Sprinkle croutons across the surface of the soup. Add sliced gruyere cheese and serve.

Pro tip: Cook for another 15 minutes to melt cheese even further.
