Garlic-Parmesan Sweet Potatoes

Garlic and Parmesan. Hard to find two words that seem so happy snuggled up to each other. Pretty much anything gets better when these two ingredients are in the mix. Pretty much any kitchen smells insanely good when something involving these two ingredients is in the oven or on the stove. And pretty much any meal is elevated when a side dish involving garlic and Parmesan is on the plate.

How to Roast Sweet Potatoes

So, this is another dumb-easy recipe. One small tip—remember to line the rimmed baking sheet with foil, as it will make you clean up so much easier. Just spray the foil with nonstick spray and spread the sweet potatoes on the foil. Drizzle over the butter, then season with salt and pepper.

Roast for about 20 minutes, then pull them out, and finish them off by sprinkling over the minced garlic and the grated Parmesan.

Back in the oven they go for another 10 to 15 minutes, until they are nicely browned in spots, and the Parmesan has turned golden and crispy, and your house smells like magic.
