Ingredients

  • 3 tbsp butter
  • 2 large jumbo yellow onions, sliced into rings
  • 1/2 tbsp white sugar
  • 1/4 cup cooking sherry
  • 6 cups reduced-sodium beef broth
  • 1/2 tsp seasoning salt or to taste
  • 1/4 teaspoon dried thyme
  • French bread
  • Shredded Parmesan cheese
  • Shredded Mozzarella cheese

Instructions

  1. Melt butter in a large pot over medium-high heat.
  2. Once melted, add onions and cook onions until they become translucent, about 10 minutes.
  3. Sprinkle onions with sugar; reduce heat to medium.
  4. Cook, stirring constantly, until onions are soft and browned.
  5. Stir sherry into onion mixture and scrape bottom of pot to dissolve brown bits from the pot.
  6. Transfer onion mixture into a crock pot and add in beef broth.
  7. Season to taste with seasoning salt; stir in thyme.
  8. Cover crock pot and cook on High for 4 to 6 hours or Low for 8 to 10 hours.

Before Serving

  1. Arrange a slice(s) of French bread on pan, cover with shredded cheeses.
  2. Broil until cheese is melted, bubbly and beginning to brown on edges.
  3. Top a cup or bowl of soup with cheesy French bread and serve.

Recipe Notes

You can substitute Gruyere and Emmental cheeses for the Mozzarella and Parmesan; I simply used what we had on hand.
