Preheat the oven to 400°F and line a medium baking sheet with parchment paper to prevent sticking and make cleanup easier. Meanwhile, gather the ingredients: crumbled blue cheese, minced garlic, sliced white bread, blanched asparagus spears, melted butter, softened cream cheese, beaten egg white, kosher salt, freshly ground black pepper, and mayo.

In a small bowl, combine the softened cream cheese with minced garlic, and season it with salt and pepper. Stir until all the ingredients are well combined, creating a flavorful cream cheese mixture.

Taking a slice of white bread, flatten it slightly with a rolling pin to make it easier to roll. Then, spread a thin layer of melted butter on each slice. Next, spread about 1/2 tablespoon of the prepared cream cheese mixture onto each slice of bread.

In the center of each bread slice, place a blanched asparagus spear. Then, roll the bread around the asparagus until the bread ends meet, creating a neat bundle. Once all the bites are assembled, brush the tops with beaten egg white for a golden finish.

Place the assembled bites onto the prepared baking sheet and bake them in the preheated oven for about 5 minutes,and the cream cheese is warmed through.

Once baked to perfection, remove the asparagus bites from the oven and let them cool slightly. To serve, arrange them on a platter and serve with a side of mayo for dipping, if desired. These flavorful and elegant appetizers are ready to impress!
