Prep and Cook Time
- Planning: 15 minutes
- Cooking: 40 minutes
- Total Time: 55 minutes
yield
- Serves: 2 mugs
Difficulty Level
- Easy to Medium
Ingredients
- 3 large yellow onions (thinly sliced)
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon sugar (to enhance caramelization)
- 2 garlic cloves (minced)
- 4 cups beef broth (preferably low-sodium for control)
- 1/2 cup dry white wine (optional,for deglazing)
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and freshly ground black pepper to taste
- 4 slices rustic baguette (toasted,about 1/2-inch thick)
- 1 cup grated Gruyère cheese (or Swiss cheese for melting)
Instructions
- Choose the perfect onions: Start by peeling and slicing 3 large yellow onions very thinly. Yellow onions offer sweetness and balance the broth beautifully.
- Caramelize the onions: In a heavy-bottomed skillet,melt 2 tablespoons butter with 1 tablespoon olive oil over medium heat. Add sliced onions and 1 teaspoon sugar to speed up caramelization. Sauté, stirring occasionally, for about 30-35 minutes until deep golden and fragrant, adjusting heat to prevent burning.
- Add garlic and deglaze: Stir in minced garlic and cook for 1 more minute.Pour in 1/2 cup dry white wine to deglaze the skillet, scraping up all browned bits. Let the liquid reduce by half to concentrate flavor.
- Simmer the broth: Transfer caramelized onions into your mug or a small pot, add 4 cups beef broth, and sprinkle in fresh thyme. Season with salt and pepper. Simmer gently for 10 minutes to marry the flavors.
- Prepare toasted crouton topping: While the broth simmers, toast rustic baguette slices until golden and crisp. Generously top each with grated Gruyère cheese.
- Assemble and broil: pour hot soup into your soup mug, float a cheesy toasted crouton on top, and place under a preheated broiler for 3-5 minutes, or until cheese bubbles and turns a luscious golden brown.
- Serve instantly: Remove from the broiler with care and let it cool just slightly before diving into your Cozy French Onion Soup in a Mug with Toasted Crouton Delight.
Tips for Success
- Onions: Yellow onions are preferred for their perfect balance of sweetness and slight pungency-avoid white onions which can be sharper in flavor.
- Broth Quality: A rich, full-bodied beef broth creates depth; homemade or trusted store-bought brands like [Kettle & Fire Beef Broth](https://www.kettleandfire.com/products/beef-bone-broth) are excellent choices.
- Cheese Variations: Gruyère is classic, but a blend with Emmental or fontina adds gourmet creaminess and meltability.
- Make-ahead: Caramelized onions can be stored for several days in the fridge, making weeknight soup assembly a breeze.
- Wine Substitute: Omit wine for a non-alcoholic version; use a splash of apple cider vinegar or extra broth instead to deglaze.

Q2: How do you achieve those perfectly caramelized onions that define this soup?

Q3: What’s the secret to the toasted crouton delight on top?

Placing these toasted croutons atop the soup provides a satisfying crunch that contrasts beautifully with the silky broth underneath.
Q4: Can cheese be included in this mug version, and if so, what do you recommend?
A4: Absolutely-no French onion soup is complete without a bubbly cheese crowning glory! Gruyère is the classic choice, prized for its nutty, melt-friendly qualities.

Sprinkle a generous handful over the croutons, then pop the mug under the broiler or in a toaster oven just long enough to get that glorious golden-brown melt.
