Equipment

  • 4 Heatproof bowls

Ingredients

  • 5-6 medium yellow onions, peeled, and sliced thinly
  • 2 tbsp. butter
  • 2 tbsp. extra virgin olive oil
  • 1 tsp salt
  • 1/2 tsp thyme dried or fresh
  • 1/2 tsp garlic powder
  • 1/4 tsp rosemary dried or fresh
  • 2 tbsp. flour
  • 1/2 cup dry white wine
  • 4 cups beef broth
  • 1 tbsp. red wine vinegar
  • 1 day stale French baguette sliced into thick slices
  • 4 thick slices of provolone cheese I love Tillamook's provolone
  • 1 1/2 cups shredded Gruyere cheese
  • Fresh cracked black pepper
  • ground nutmeg
  • chives, minced About 1/2 teaspoon for each serving.

Instructions

  • In a Dutch oven or soup pot add the butter and oil over med/low heat.
  • Now add the onions, thyme, rosemary, garlic, and salt.
  • Stir well and cook for about 35-40 minutes until the onion are deeply caramelized.
  • Now add the flour, stir and pour in the wine and broth. Scrape up any bits from the bottom of the pan.
  • Now bring it to a simmer, cover and cook for 15 minutes.
  • After 15 minutes is up pour in the vinegar and give it a good stir.
  • You can taste and adjust any seasonings but go easy on the salt since we are adding lots cheese which is salty.
  • Turn off the soup and set the oven to high broil.
  • In heatproof bowls, divide the soup evenly. Add in 2-4 slices of the baguette.
  • Now top with a slice of provolone cheese, and sprinkle some shredded gruyere on the provolone slice.
    Top each bowl with fresh cracked pepper and a pinch of nutmeg. DON'T SKIP THIS PART.
  • Set the bowls on a baking sheet and broil until the cheese is golden and melty. It takes 2-5 minutes. Make sure to keep an eye on them because they will burn quickly!
  • Place the bowls on a small heatproof plate and garnish with fresh chopped chives.
  • Be careful of the hot bowls. Now dive in and try the best French onion soup ever!
  • ENJOY!
