Fire up the broiler on high. While that warms up, chop off the ends of the sweet potatoes and cut them into chunky, 1.5-inch sections.
02 -
If you're boiling (great for caramelization): Toss the sweet potato chunks in a salted water pot, bring it to a boil, and let them cook about 20 minutes with a lid on, until just tender. Or to roast: Bake them at 375°F for 25-30 minutes. Whichever way you go, let them chill enough to touch afterward.
03 -
Lay a layer of cooking spray on your baking sheet. Spread the cooled sweet potato pieces out, and use a fork to gently press each one flat without breaking them apart.
04 -
Mix the warm, melted butter with parsley and crushed garlic, then give each smashed piece a generous drizzle. Sprinkle with salt and pepper, then finish with a quick olive oil spritz.
05 -
Broil the smashed potatoes until they turn a crisp, deep golden shade, about 15 minutes. Sprinkle the shredded Parmesan over them and pop them back under the broiler just until gooey and melty.

Once done, scatter a bit of extra parsley and a pinch of salt over them. Serve these crispy-on-the-outside, soft-in-the-center beauties right away!
