Preheat your oven to 425 degrees Fahrenheit
Scrub your potatoes and pat dry
Make 1/8" slits into your potatoes being careful not to cut all the way through
In a small bowl, combine your melted butter, olive oil, garlic powder, and smoked paprika
Lay out your potatoes onto a baking tray and use a brush to generously coat each potato with the fat mixture. Gently separate the slits to get the fat mixture in between the layers
Season everything generously with salt and pepper
Bake for 60-70 minutes (bake time may vary depending on the size of your potato)
Garnish with sliced green onion (*optional)
