Wash and clean the Shishito peppers. Make a slit lengthwise on each pepper, leaving a quarter inch at the top and bottom uncut.
In a small mixing bowl, combine cream cheese, garlic powder, and red pepper flakes. Whip the ingredients until you achieve a fluffy consistency.
Using a teaspoon, stuff each Shishito pepper with the cream cheese mixture.
Arrange the stuffed peppers on a baking tray.
Bake the peppers in the preheated oven for about 7 minutes or until the peppers start to blister.
Remove the tray from the oven and let the peppers cool a bit before serving.
Serve immediately.
Notes
Have leftovers? Here is the instruction, shishito peppers lose their firmness upon reheating. Hence, you can use leftovers as a salad topping or as an ingredient in a casserole.
