A grilled cheese sandwich is both one of my favorite comfort food recipe and also one of my go to's when I need to make dinner in a hurry. All you need is good bread, flavorful cheese, and butter and you've got a satisfying meal. Bonus points if you dress it up like I did this sandwich!
A good sharp cheddar makes a great base for this sweet and savory sandwich. A little homemade honey mustard adds some nice sweetness and great zip (from the Dijon) and it all comes together with sweet caramelized onions. This sandwich only requires a few ingredients and caramelizing the onions is really the only time consuming part of the process-- and it can be pretty hands off, so you can get the rest of the sandwich prepped while the onions cook.
With this recipe you can make a favorite comfort food recipe into something really special!
- 3 Tbs. butter, divided
- 1/2 Tbs. olive oil
- 1 Vidalia onion
- 1/4-3/4 cup dry white wine or chicken broth, as needed
- 1 1/2 Tbs. Dijon mustard
- 1/2 Tbs. honey
- 4 slices of sourdough bread
- 4 thick slices of cheddar cheese
Heat 1 Tbs. butter and the olive oil in a medium skillet over medium heat. Once melted, swirl in the pan and add onions and a pinch of salt and cook, stirring often, until the onions are very soft and slightly browned, at least 15-20 minutes. Pour in the wine or broth (as needed) to deglaze the pan throughout the cooking process to prevent onions from getting too browned. Remove onions from heat and set aside.
Spread remaining butter equally on the outside of each of the 4 slices of bread.
In a small bowl, whisk together the mustard and honey until fully combined. Spread the honey mustard mixture evenly on the inside of each of the four slices of bread.
On one slice of bread (buttered side out), layer 1 slice of cheese and top with an even layer of caramelized onions. Top with the second slice of cheese and the second slice of bread with the buttered side facing out. Repeat with second sandwich.
Place both sandwiches carefully in the hot skillet and cover. Cook for about 4 minutes or until cheese begins to melt and the bottom side is golden brown. Gently flip the sandwich over (being careful not to lose the onions inside), cover again, and cook for another 2-3 minutes until golden.
Remove from skillet, allow to cool for 1-2 minutes, slice, and serve warm.
