How to Make French Onion Grilled Cheese

Step 1: Heat the Skillet

Heat butter and extra virgin olive oil in a large skillet over medium heat.

Step 2: Caramelize the Onions

Add the sliced onions along with Worcestershire sauce, spicy brown mustard, Italian seasoning, garlic powder, sugar (if using), black pepper, and salt. Stir to combine.

Step 3: Prepare to Grill

Heat a clean skillet over medium heat.
Spread mayonnaise on one side of each slice of bread if desired for extra crispiness.

Common Mistakes to Avoid

Making the perfect French Onion Grilled Cheese can be tricky. Here are some common mistakes to avoid for a delicious outcome.

• Bold Use of Low-Quality Ingredients: Using cheap bread or cheese can lead to a subpar sandwich. Opt for fresh, high-quality options for the best flavor and texture.
• Bold Overcooking the Onions: Cooking onions too quickly can result in them burning instead of caramelizing. Keep the heat at medium and stir occasionally to achieve that sweet, golden color.
• Bold Skipping the Seasoning: Neglecting to season your onions properly can make your grilled cheese bland. Don’t forget spices like Italian seasoning and black pepper to enhance the flavor.
• Bold Not Using Enough Cheese: A good grilled cheese needs plenty of gooey cheese. Make sure to layer both Provolone and Gruyère generously for that ooey-gooey texture.
• Bold Ignoring Proper Toasting Techniques: Toasting your bread on too high heat can lead to burnt outsides with cold insides. Cook over medium heat for even browning and melted cheese.

Storage and Reheating
