Instructions  

Step 1: Caramelizing the Onions  

1. Heat a skillet over medium-low heat and add the olive oil and butter.  

2. Once the butter melts, add the sliced onions and stir to coat them evenly in the fat.  

3. Sprinkle a pinch of salt and add a teaspoon of sugar if you like a sweeter touch.  

4. Cook the onions on low heat, stirring occasionally, for 20-30 minutes. The goal is a deep golden-brown hue, and this slow process intensifies the flavor.  

5. If the onions are sticking, deglaze the pan with a splash of water or balsamic vinegar. When they're soft and caramelized, set them aside.  

Step 2: Assemble the Sandwich  

1. Lay out your bread slices and generously butter one side of each slice.  

2. Flip the slices over so the unbuttered side faces up. Layer half of the grated cheese on two slices.  

3. Spread a generous amount of the caramelized onions over the cheese layer.  

4. Top with the remaining cheese and close the sandwiches with the other slices of bread, buttered side out.  

Step 3: Grill to Perfection  

1. Heat a skillet or griddle over medium heat. Add a small pat of butter for extra crispiness.  

2. Place the sandwiches in the skillet and cook on each side for 3-4 minutes. Press gently with a spatula to ensure the cheese melts evenly.  

3. Flip carefully and cook the other side until the bread is golden brown and the cheese is perfectly melted.  

Serving Suggestions  

For the ultimate comfort meal, pair your caramelized onion grilled cheese with a bowl of creamy tomato soup. A side salad with a tangy vinaigrette complements the richness of the sandwich beautifully.  

Tips for the Best Results  

• Cheese Matters: Using a mix of cheeses adds depth and balance. Gruyère offers nuttiness, cheddar brings sharpness, and mozzarella gives you that gooey stretch.  

• Low and Slow: Patience is key when caramelizing onions. Rushing the process can lead to burnt or unevenly cooked onions.  

• Bread Choice: Choose hearty bread that can withstand the filling without becoming soggy. Sourdough and artisan loaves are top picks.  

Why This Recipe Works  

The magic of this caramelized onion grilled cheese lies in the harmonious combination of sweet, savoury, and creamy flavours. Caramelized onions bring a natural sweetness that contrasts beautifully with the salty richness of melted cheese. The crisp, buttery exterior provides the perfect textural balance, making each bite irresistibly satisfying.  

Variations to Try  

• Add Protein: Include thin slices of roast beef, turkey, or crispy bacon for an extra layer of flavour.  

• Experiment with Spreads: Try a smear of Dijon mustard, fig jam, or even a hint of sriracha to ramp up the taste.  

• Go Veggie: Add sautéed mushrooms, roasted red peppers, or fresh spinach for a vegetarian twist.
