Oven Baked 3-Ingredient Parmesan Smashed Potatoes

Ingredients:

Step-by-Step Directions:

Step 1: Prep the Oven and Sheet Environment: Preheat your oven to 425°F (220°C). Lightly grease a large baking sheet with a small dab of melted butter. This prevents the skins from sticking while laying down a rich fat foundation to help fry the potato bottoms into a beautiful, uniform crunch.

Step 2: Simmer to Fork-Tender: Rinse your 1 1/2 pounds of baby potatoes thoroughly, leaving the skins completely intact. Place them into a medium saucepan, cover with cold water by about an inch, and bring to a rolling boil over medium-high heat. Drop to a gentle simmer and cook for 12 / to 15 / minutes until a fork easily slides into the centers.

Step 3: Steam-Dry and Smash: Drain the potatoes cleanly into a colander. Let them sit completely undisturbed for 3 / to 5 / minutes.

Tip: Do not rush this drying step! Allowing the surface water to fully evaporate into steam is the ultimate secret to getting an ultra-crisp skin; residual surface water will trap steam in the oven and leave your potatoes soggy.

Spread the dry spuds across your baking sheet. Use the flat bottom of a sturdy glass or mason jar to gently press down on each potato until it cracks open and flattens to about 1/2 / inch thick.

Step 4: Butter and Shell with Cheese: Brush or spoon your 4 tablespoons of melted salted butter evenly over the tops and shattered edges of every single potato. Sprinkle your 3/4 cup of finely grated sandy parmesan generously over each piece. Don’t worry if some cheese spills onto the bare pan—those loose pieces will bake into prized, crispy lace chips.

Step 5: Roast to a Lacy Blister: Slide the sheet onto the middle rack of your oven and roast for 20 / to 25 / minutes. Watch for the edges to turn a deep, golden brown and the cheese to fuse into a crisp, bubbling canopy. For maximum crunch, leave them in for an extra 3 / to 5 / minutes, watching closely to prevent the dairy sugars from scorching.

Step 6: Cool to Set and Serve: Remove the sheet from the oven and let the potatoes sit flat for 3 / to 5 / minutes to firm up. Slide a thin spatula cleanly underneath the cheese crust to lift them safely from the pan. Pile them high in a warm serving bowl and serve immediately while screamingly hot.
