Asparagus baked with Parmigiano and butter is an elegant vegetarian spring side. This fresh mediterranean dish is healthy, protein-rich, and a family favorite during asparagus season.
Preheat your oven to 400°F for consistent heat throughout baking.
Trim tough ends from asparagus and arrange spears in a single layer in a greased baking dish.
Dot the asparagus evenly with unsalted butter; this ensures moisture retention during roasting.
Sprinkle Parmigiano-Reggiano cheese generously over the spears, followed by kosher salt and black pepper.
Bake uncovered for 18–22 minutes until the asparagus is tender but still vibrant and the cheese forms a golden crust. Serve hot.
