Guys. It is a cold winter in Los Angeles.

We’ve discussed this. Anything below 60 does not bode well with my LA peeps. Except every time I get in the car, it’s actually been 37 degrees F!

Nope. No bueno, guys.

So Butters and I have been holed up at home, making THE CLASSIC French onion soup.

And when I say classic, I mean classic. No fuss, no frills.

It’s just your classic, traditional French onion soup. With the most perfect caramelized onions in a cozy stock with fresh thyme sprigs, finished off with crusty French baguette slices and two cheeses – Swiss and Gruyere – conveniently melted on top.

See, I told you. It’s a classic.

Ingredients

  • ¼ cup unsalted butter
  • 3 pounds medium sweet onions, sliced
  • 2 cloves garlic, minced
  • cup dry white wine
  • 6 cups beef stock
  • 4 sprigs fresh thyme
  • 2 bay leaves
  • 2 teaspoons white wine vinegar
  • Kosher salt and freshly ground black pepper, to taste
  • 12 French baguette slices
  • 1 cup shredded Swiss cheese
  • 1 cup shredded Gruyère cheese

Instructions

  • Melt butter in a large stockpot or a Dutch oven over medium heat. Add onions, and cook, stirring often, until deep golden brown and caramelized, about 30-40 minutes.*
  • Stir in garlic until fragrant, about 1 minute.
  • Stir in wine, scraping any browned bits from the bottom of the stockpot.
  • Stir in beef stock, thyme and bay leaves. Bring to a boil; reduce heat and simmer, stirring occasionally, until slightly reduced, about 15-20 minutes. Remove and discard thyme sprigs and bay leaves.
  • Stir in white wine vinegar; season with salt and pepper, to taste.
  • Preheat oven to broil.
  • Place baguette slices onto a baking sheet. Place into oven and broil until golden brown on both sides, about 1-2 minutes per side; set aside.
  • Divide soup into ramekins or ovenproof bowls. Place onto a baking sheet. Top with baguette slices to cover the surface of the soup completely; sprinkle with cheeses. Place into oven and broil until golden brown and cheeses have melted; about 2 minutes.
  •  Serve immediately.

Notes

*If the onions begin to burn on the bottom of the pot, reduce heat slightly and stir in 1/4 cup water.
