Ingredients
- 4 slices sourdough bread
- 150 g (5 oz) Gruyere cheese, grated or thinly sliced
- 1 large yellow onion, thinly sliced
- 3 tbsp unsalted butter (1 tbsp for onions, 2 tbsp softened for grilling)
- 1 tsp olive oil
- 1/4 tsp salt
- 1/2 tsp sugar (optional, for extra sweetness)
- Fresh thyme leaves or a pinch of black pepper (optional)
Instructions
- Caramelize the onions
- Heat 1 tablespoon butter and olive oil in a skillet over medium heat. Add the sliced onions and salt. Cook, stirring occasionally, for 15-18 minutes until golden brown and caramelized. Add sugar halfway through for deeper sweetness, if desired. Set aside.
- Prepare the bread
- Lay out the sourdough slices. Butter one side of each slice.
- Assemble the sandwiches
- Place half the cheese on the unbuttered side of two slices. Top each with half the caramelized onions, then sprinkle with thyme or black pepper if using. Cover with remaining cheese, then top with the other bread slices, buttered side facing out.
- Cook the sandwiches
- Heat a large skillet or griddle over medium-low heat. Place sandwiches in the pan. Cook for 3-4 minutes per side, pressing gently, until bread is golden and cheese is melted.
- Serve
- Remove from pan, let rest 1 minute, then slice and serve hot.
Zusatztipps für die Zubereitung
For the perfect caramelized onions, patience is key. Don't rush the process by turning up the heat - slow and steady wins the race here. The onions should gradually transform from raw to translucent to golden and finally to a deep amber color. This slow cooking process develops the natural sugars in the onions, resulting in that signature sweet, complex flavor that makes this sandwich special.
Varianten und Anpassungen
While this sandwich is perfect as is, you can easily customize it to your taste. Try adding a smear of Dijon mustard for a tangy kick, or incorporate a handful of baby arugula for freshness and peppery contrast. If Gruyere isn't available, other excellent melting cheeses like Comté, Emmental, or even a sharp cheddar would work beautifully. For meat lovers, adding a few slices of crispy bacon creates a decadent variation.
Serviervorschläge
This upgraded grilled cheese pairs beautifully with a bowl of tomato soup for the ultimate comfort food combination. For a lighter option, serve alongside a crisp green salad dressed with a simple vinaigrette to cut through the richness of the sandwich. A glass of crisp white wine or a light beer makes this simple sandwich feel like a special occasion meal.
