What You'll Need

• Ingredients (per sandwich):
  • 2 slices sourdough bread (about ¾-inch thick)
  • 2–3 oz cheese (mix cheddar + Gruyère for flavor)
  • 2 tbsp butter or 1 tbsp butter + 1 tbsp mayonnaise
• Tools:
  • Cast-iron skillet or nonstick pan
  • Spatula, cheese grater, serrated knife
  • Small bowl for softened butter

Tip: Use day-old sourdough for better structure and less sogginess. Grate part of the cheese for faster melting.

Preparing Your Ingredients

• Grate 1 oz of cheese and thinly slice 1–2 oz for texture contrast.
• Spread butter thinly and evenly on the outside of each bread slice.
• If you prefer a tangy, crisp edge, spread 1 tsp mayonnaise on the outside instead of butter.
• Assemble sandwich with grated cheese first, sliced cheese on top, and close gently.

Pro tip: Press the sandwich lightly so the layers contact evenly. Don’t compress hard — the bread should stay airy.

Step-by-Step Instructions for Cooking

1. Heat pan to medium-low — wait until it’s evenly warm.
2. Place sandwich butter-side down. Cook 3–4 minutes until golden brown.
3. Reduce heat if crust browns too fast; you want cheese to melt before bread burns.
4. Flip and cook another 3 minutes, pressing gently with spatula for even heat contact.

• Watch for a deep golden crust and a visible cheese ooze at the seam.
• If cheese isn’t fully melted, cover the pan for 30–60 seconds to trap heat.
• Warning: High heat gives a burnt exterior and unmelted interior. Keep it steady.

Shortcut: Use a lid or a sheet pan on top of the sandwich to speed melting without raising the burner.

Serving and Storage Tips

• Let sandwich rest 1 minute before slicing to avoid cheese runoff.
• Slice diagonally for a dramatic cheese pull — great for photos and sharing.
• Store leftovers wrapped in foil in the fridge for up to 2 days. Reheat in a skillet on low to restore crunch.
• Freeze assembled (un-cooked) sandwiches for up to 1 month. Cook from frozen, add 1–2 minutes per side.

Variations:

• Add crispy bacon, sliced tomato, or caramelized onions.
• Swap cheeses: Gouda or Fontina melt beautifully for a milder flavor.
