Ingredients

For the Caramelized Onions

• 3 tablespoons Olive Oil
• 8 Small Onions (Sliced)
• 1 Rosemary Sprig
• 2 Bay Leaves
• 3 Thyme Sprigs
• ½ cup Brown Sugar
• ½ cup red grape juice
• 1 tablespoon Balsamic Vinegar

For the Sandwich

• 1 10.5 ounce can French Onion Soup
• 8 slices Thick Sliced Bread
• ½ cup Butter (Softened)
• 1 cup Gruyere Cheese (Shredded)
• 1 cup White Cheddar Cheese (Shredded)
• Onion Jam
• 3 tablespoons Grated Parmesan Cheese

How to Make French Onion Grilled Cheese

Step 1: Prepare the Caramelized Onions

Start by heating the olive oil in a skillet over medium heat. Add the sliced onions and cook them until they are soft and golden brown, about 20-25 minutes. Stir occasionally to prevent sticking.

Step 2: Add Herbs and Sugars

Once the onions are caramelized, add in the rosemary sprig, bay leaves, thyme sprigs, brown sugar, red grape juice, and balsamic vinegar. Mix well and let it simmer for another 10-15 minutes until thickened. Remove herbs before using.

Step 3: Assemble Your Sandwiches

Spread softened butter on one side of each slice of bread. On the unbuttered side, layer shredded gruyere cheese, cheddar cheese, onion jam, and about 2 tablespoons of your caramelized onion mixture. Top with another slice of bread.

Step 4: Grill Your Sandwiches

Place sandwiches butter-side down in a clean skillet over medium heat. Cook for about 3-4 minutes on each side or until golden brown and crispy. Sprinkle grated Parmesan on top during the last minute of cooking for an extra cheesy finish.

Step 5: Serve Hot

Remove sandwiches from skillet once they are crispy and melted inside. Allow them to cool slightly before slicing in half. Enjoy warm with additional onion jam if desired!

Common Mistakes to Avoid

When making your French onion grilled cheese, it’s easy to make some common errors. Here are a few mistakes to watch out for to ensure your sandwich is perfect.

• Boldly Overlooking the Cheese: Using low-quality cheese can lead to a bland flavor. Always opt for good-quality gruyere and cheddar for the best melting and taste.
• Boldly Skipping the Onions: Not caramelizing the onions properly can result in a lack of sweetness. Take your time to cook them until they are golden brown and fragrant.
• Boldly Ignoring Butter Quality: Using margarine instead of butter can change the flavor profile. Stick with real butter for that rich taste and texture.
• Boldly Rushing the Sandwich: Grill your sandwich on too high heat, which can burn the bread while leaving the cheese unmelted. Cook it slowly over medium heat for even results.
• Boldly Underestimating Onion Jam: Forgetting to add onion jam can lead to missing out on a burst of flavor. Spread it generously for an added layer of taste.

Storage and Reheating

• Boldly Microwave Method: Place on a microwave-safe plate and cover with a damp paper towel. Heat in 30-second bursts until warm, but be aware that this may make the bread soggy.
