Ingredients:
Caramelized Onions:
2 large onions, thinly sliced 🧅
2 tbsp butter 🧈
1 tbsp olive oil 🍈
1/2 tsp salt 🧂
1 tsp sugar (optional, for extra sweetness) 🍬
Sandwich Assembly:
8 slices sourdough bread 🍞
4 tbsp butter, softened 🧈
1 cup Gruyère cheese, shredded 🧀
1 cup mozzarella cheese, shredded 🧀
Fresh thyme or parsley, for garnish (optional) 🌿
Directions:
Step 1: Caramelize the Onions
In a large skillet, melt butter with olive oil over medium heat.
Add the sliced onions, salt, and sugar (if desired) to the skillet. Stir occasionally, cooking for 25-30 minutes, until the onions are soft, golden brown, and caramelized. You may need to lower the heat slightly to prevent burning.
Once caramelized, remove from heat and set aside.
Step 2: Assemble the Sandwiches
Spread butter on one side of each slice of sourdough bread.
On the unbuttered side, layer the shredded Gruyère cheese and mozzarella cheese.
Add a generous portion of the caramelized onions on top of the cheese.
Top with the second slice of bread, making sure the buttered side is facing out.
Step 3: Cook the Sandwiches
Heat a skillet over medium heat.
Place each sandwich in the skillet and cook for 3-4 minutes per side, pressing gently with a spatula, until the bread is golden brown and the cheese is melted and gooey.
Step 4: Serve and Garnish
Remove the sandwiches from the skillet and slice them in half.
Garnish with fresh thyme or parsley, if desired, for a touch of freshness.
Serve the sandwiches warm and enjoy!

Pro Tips for the Perfect French Onion Grilled Cheese:
Caramelizing the Onions: Take your time when caramelizing the onions. The slower they cook, the sweeter and more flavorful they will become. If they start to brown too quickly, lower the heat and stir more frequently.
Cheese Variety: Gruyère is a classic choice, but you can also mix it up with other cheeses like Swiss or Cheddar for different flavor profiles.
Bread Choice: Sourdough bread is perfect for this sandwich because of its tangy flavor and sturdy texture, but feel free to use other types of bread like French baguette or rye.
Extra Crispy: For extra crispy, golden bread, you can use a panini press or cook the sandwiches in a grill pan.
Pairing Suggestions:
Serve with a bowl of tomato soup for a classic combination.
Pair with a refreshing green salad for a lighter meal.
This French Onion Grilled Cheese is a flavorful twist on a classic, perfect for satisfying your cheese cravings with a sweet, savory touch. Whether you’re making it for lunch, dinner, or as a comforting treat, this sandwich is sure to become a favorite!
