Preheat oven to 400. Slice red onion julienne style, mince garlic, and finely chop parsley.
Next, Wash potatoes and place them each onto their own piece of foil. (about 66 inches or enough to wrap the whole potato when finished) Then, slice each potato hasselback style, not quite all the way through.
Finally, using 1 pat of butter for each potato, push the butter, bit by bit in between each slice in the potatoes. After that push a piece of onion in between each slice also. This will hold them open a bit to add your herbs and spices. Then, season to taste with salt, pepper, and seasoning salt. Add the minced garlic and chopped parsley evenly to each potato as well.
Finally, top each potato with a shake or two of grated parmesan. Wrap tightly in foil. Place on a cookie sheet and bake for 45-60 minutes or until potatoes are tender.
Serve with Breakfast, Lunch, Dinner, or even as a Snack! Enjoy with a dollop of sour cream or your favorite potato toppings!
