Step-By-Step Instructions

Step 1: Caramelize the Onions

1. Heat 1 tbsp olive oil and 1 tbsp butter in a pan over medium heat.
2. Add your sliced onions, sprinkle with sugar, salt, and pepper. Stir frequently for about 15-20 minutes until the onions are deeply golden and caramelized.
3. Add the beef broth and cook for another 2-3 minutes until reduced. This adds incredible French onion soup flavor!

Step 2: Build the Sandwich

1. Spread butter on one side of each bread slice.
2. Place two bread slices butter-side down in a clean skillet over medium heat.
3. Sprinkle a generous layer of Gruyère cheese on each slice, then top with your caramelized onions. Add a pinch of thyme if desired.
4. Place the remaining bread slices on top, butter-side up.

Step 3: Grill to Perfection

1. Cook each sandwich for about 3-4 minutes per side, pressing gently with a spatula until the bread is crispy and golden and the cheese is melted.
2. Slice and serve immediately for ultimate gooey goodness!

Pro Tips for the Perfect Grilled Cheese

🍞 Choose the Right Bread: Thick slices like sourdough, French bread, or Texas toast hold up best.

🥣 Pair It With Soup: Try it with this Creamy Taco Soup for the ultimate comfort meal combo.

Budget Tips

💰 Save on Cheese: While Gruyère is iconic, you can swap it for Swiss, Provolone, or Monterey Jack for a more affordable option.
