Best Ever Grilled Cheese Sandwiches

You can also use your imagination to come up with other fillings, such as chives, a sprinkle of Parmesan cheese or Italian seasoning, and even a spoonful of salsa. —Edie DeSpain, Logan, Utah

    We've made grilled cheese sandwiches like this for many years, minus the onion. We often use thinly sliced ham instead of bacon. Use any kind of bread you prefer. We like good-quality French or Italian bread. These sandwiches are terrific in late summer with garden tomatoes.

    Very good and pretty easy especially cooking these on the George Foreman.

    This was a great recipe. It was not your run-of-the-mill sandwich - great flavors going on! It was great as it was, but you could change it up many ways.

    We made this three days ago for Girl's Friday Night and the sandwiches were great hit with everyone! We had a lot of leftover meats and cheeses from a food day at work and so we made a variety of these sandwiches with different meats using a paninni sandwich maker to grill them. One of my friends even sprinkled garlic and Italian seasoning on the butter for grilling. Great idea! Thanks for the good recipes, TOH!

    Good stuff, mix in what you prefer. The mayo & mustard give a nice tang that reminds me of a deviled egg, my favorite. BTW if you have one, dust off your George Foreman grill to press the sandwiches. It works amazing...I don't use them for cooking anything else. No need to butter the bread, just swipe the griddle with butter & you're good to go. Crunchy outside & gooey inside. Yummo. Thanks TOH & the OP for taking a simple grilled cheese & helping me think outside the box.

    I heard of a recipe that calls for putting some of the grated cheese on the outside with the butter to make a cheesy crust on the outside, yum

    Good to know not everybody makes the same old, same old when it comes to grilled cheese sandwiches. This one is refreshingly different, creative, not boring.
