4. Swap Butter for Mayo
When it comes to making a grilled cheese sandwich, the go-to recipe will have you slathering butter on both sides of the bread and frying it in a pan. However, if you truly want a grilled cheese sandwich that is browner and crispier, try putting mayo on the bread instead of butter.
The fat and oils that are found in the mayo will help the bread crisp up better. In addition, the mayo will help to provide the grilled cheese sandwich with a bit of flavor as well. When you are using mayo, make sure that you are generous with it. You want to make sure that the entire side of the bread is covered.
This will ensure that the entire piece of the bread gets that crispy texture that you desire in the perfect grilled cheese sandwich. Make sure that you are also using good quality cheese!
