difficulty Level

medium – Great for adventurous home cooks looking to hone essential skills like onion caramelization and broiling cheese.

Ingredients

• 2 large yellow onions, thinly sliced
• 1 tbsp unsalted butter
• 1 tsp olive oil
• 1/2 tsp salt
• 1/4 tsp sugar (to aid caramelization)
• 1 clove garlic, minced
• 3/4 cup beef broth (or vegetable broth for vegetarian option)
• 1/4 cup dry white wine (optional, for depth)
• Fresh thyme sprig or 1/4 tsp dried thyme
• Salt and black pepper, to taste
• 1 slice rustic French bread (about 1/2 inch thick)
• 1/2 cup shredded Gruyère cheese (or Swiss cheese)
• A pinch of smoked paprika (optional, for subtle warmth)

Instructions

1. Caramelize the Onions: In a small skillet over medium-low heat, melt the butter with olive oil. Add the thinly sliced onions, salt, and sugar. Sauté gently for about 30-40 minutes, stirring frequently until the onions turn golden brown and intensely sweet. Add a splash of water if they begin to stick.
2. Add Garlic and Deglaze: Stir in the minced garlic and cook 1 minute until fragrant. Pour in the white wine (if using), scraping up any brown bits from the pan. Let simmer until the wine reduces by half, about 3-4 minutes.
3. simmer the Broth: Add the beef broth and thyme, bring to a gentle boil, then reduce heat and simmer for 10 minutes. Season with salt, pepper, and smoked paprika to taste. Remove the thyme sprig before serving.
4. Prepare Toasted Crouton Twist: While broth simmers, preheat your oven’s broiler.Cut the rustic bread slice into crouton-sized cubes or long strips. Place on a baking sheet, drizzle with olive oil, and toast under the broiler for 2-3 minutes or until golden and crispy, watching closely to prevent burning.
5. Assemble in Mug: Pour the hot soup into your favorite mug. Top generously with toasted croutons, then sprinkle shredded Gruyère cheese evenly on top.
6. Broil for Melty Perfection: Place the mug on a baking tray and broil in the oven for 2-4 minutes until the cheese bubbles and turns golden brown, forming a deliciously gooey crust.
7. Garnish and Serve: Remove carefully, garnish with a fresh thyme leaf, and enjoy warm straight from the mug.

Tips for Success

• Patience is key: Slow-caramelizing onions release their rich, natural sweetness. Avoid rushing by turning heat too high.
• onion variety: Yellow onions offer the perfect balance of sweetness and pungency; avoid using white onions, which can be too sharp.
• crouton alternatives: Use baguette slices or sourdough for added texture variations.
• Make it vegetarian: Substitute beef broth with a rich vegetable broth and use vegetarian cheese.
• Make-ahead: Caramelized onions can be prepared 2 days in advance and refrigerated.
• Watch the broiler: Cheese can quickly burn; stay attentive during the final step.

Serving Suggestions

Enjoy this cozy mug soup alongside a crisp green salad with a light vinaigrette to balance the richness. Garnish with finely chopped fresh parsley or chives for a pop of color. Pair with a glass of dry white wine or a malty dark beer to complement the deep onion flavors. For a cozy twist, serve in a bread boule hollowed out as an edible bowl.
