Perfect Grilled Cheese Sandwich: Crispy, Golden and Gooey

A grilled cheese sandwich is one of the simplest meals there is, but a really good one is a small piece of cooking skill: golden, crisp and buttery on the outside, with cheese melted all the way through to the edges. The difference between a soggy or burnt sandwich and a perfect one is mostly heat control and a few small tricks.

This guide shows the method that works every time, whether you are making a quick lunch, a snack for kids or the classic partner to a bowl of tomato soup. It also pairs beautifully with soups such as tomato soup and loaded baked potato soup.

The best bread

Choose a sturdy sandwich bread with a tight crumb, such as a white or sourdough loaf, cut about 1 cm (1/2 inch) thick. Very thin bread burns before the cheese melts, and very thick bread takes too long to heat through. Day-old bread works well because it holds up to the butter.

The best cheese

• Cheddar gives sharp flavor but can turn oily; use medium or mild.
• Mozzarella, Monterey Jack and Gruyère melt smoothly and stretch.
• A combination of one sharp cheese and one good melting cheese gives the best result.
• Shred or slice thinly. Shredded cheese melts faster than thick slices, and avoid pre-shredded bags with anti-caking starch if you want the creamiest melt.

The method

1. Spread butter on the outside of the bread, not in the pan. This gives an even, golden crust right to the edges.
2. Preheat a pan over medium-low heat. Medium-low is the key; high heat burns the bread before the cheese melts.
3. Cook slowly, 3 to 4 minutes per side, pressing gently, until the bread is golden and the cheese is melted.
4. Cover the pan for the last minute if the cheese needs help melting.

Tips for an extra-crispy crust

• Use mayonnaise on the outside instead of butter or mix a little with the butter; it browns evenly and gives a super crispy crust.
• Add a pinch of grated Parmesan to the outside of the bread for a crisp, salty crust.
• Rest for 1 minute before cutting so the cheese sets slightly.

Variations

• Tomato and basil: add thin tomato slices and fresh basil.
• Ham and cheese: add a slice of ham or turkey.
• Caramelized onion: add sweet onions; see our guide to caramelized onions.
• Pear and brie: a gourmet version with thin pear slices and honey.

Frequently asked questions

Why does my cheese not melt?

The heat is probably too high, so the bread browns before the cheese has time to melt. Lower the heat and cover the pan briefly.

Can I make it in an air fryer or oven?

Yes. In the air fryer, cook at 190 C (375 F) for 6 to 8 minutes, flipping once. In the oven, bake on a sheet pan at 200 C (400 F) for about 10 minutes, flipping halfway.
