Let’s Make it together
Sauté Those Onions!: Start by melting butter in a large pot over medium heat. Add thinly sliced sweet onions and sprinkle with sugar, cooking for about 30 minutes until they caramelize into golden perfection.
Add Aromatics!: Toss in minced garlic and fresh thyme during the last few minutes of cooking. Your kitchen should start smelling heavenly at this point!
Deglaze With Wine!: Pour in dry white wine to deglaze the pot while scraping up any flavorful bits stuck to the bottom. Let it simmer until reduced by half, enhancing those flavors beautifully.
Add Broth!: Pour in beef broth while bringing everything back to a gentle simmer. Allow it to cook for about 20 minutes so all flavors meld together into one comforting bowl.
Prepare Toppings!: While your soup simmers away, slice your baguette into thick pieces and toast them lightly under the broiler until crispy—perfect for holding all that cheesy goodness!
Assemble & Broil!: Ladle soup into oven-safe bowls, place toasted baguette slices on top, then generously cover with Gruyère cheese. Broil for about 3-5 minutes until bubbly and golden brown.
