Cozy Winter Onion Soup That Costs Almost Nothing — Creamy, Simple & Perfect for Cold Nights

Slice onions thinly.

Melt butter and olive oil in a large pot over medium heat.

Add onions and cook, stirring occasionally, until caramelized, about 30-40 minutes.

Stir in minced garlic and cook for 1-2 minutes until fragrant.

Pour in white wine and scrape the bottom of the pot to deglaze.

Add beef broth, thyme, bay leaves, salt, and black pepper.

Bring to a simmer and cook for 20-30 minutes to develop flavors.

Preheat the oven to broil.

Ladle soup into oven-safe bowls and top with slices of French bread.

Sprinkle Gruyère and Parmesan cheese generously over the bread.

Place bowls on a baking sheet and broil until cheese is bubbly and golden, about 3-5 minutes.

Remove from oven and let cool slightly before serving.
