Pre-heat oven to 425° and line a baking sheet with foil
To prepare the sweet potatoes, slice a 1/8” off the bottom for stability, and place a wooden spoon on either side of the potato to prevent you from slicing all the way through. Cut 1/2” thick slices all the way down the potato. Place them on the foil lined baking sheet.
To make the glaze, mix melted butter, maple syrup, garlic, rosemary, salt and pepper in a small mixing bowl.
Brush half the glaze over the potatoes and also in the slits.
Bake for 20 minutes and remove the potatoes from the oven. Brush with remaining glaze and return to the oven for another 15-20 minutes or until the inside is fork tender and the outside is a bit crispy.
Serve with a scattering of chopped pistachios and some crumbled feta. Enjoy!
