This low carb 3-ingredient parmesan roasted asparagus is exactly the kind of spring side dish my sister brought to our holiday table and completely stole the show with. It looks fancy, but it’s literally just asparagus, olive oil, and parmesan, roasted until the spears are tender-crisp and the cheese turns golden and lacy around the edges. It’s the kind of recipe you can throw together in minutes between work and dinner, but it still feels special enough for guests or a holiday spread.
Serve these parmesan roasted asparagus spears straight from the oven while the cheese is still crisp and the olive oil is glistening. They’re perfect alongside roast chicken, baked salmon, grilled steak, or a simple baked pork tenderloin. For a lighter meal, I like to pair them with a big green salad and some rotisserie chicken. They also make a great brunch side next to eggs and a slice of ham, and any leftovers are delicious chopped into an omelet or tossed into a simple salad the next day.
3-Ingredient Parmesan Roasted AsparagusServings: 4
Ingredients
1 pound fresh asparagus, woody ends trimmed
2 tablespoons extra-virgin olive oil
1/2 cup finely grated parmesan cheese (freshly grated, not pre-shredded)
Directions
Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easier cleanup.
Rinse the asparagus and pat it very dry with a clean kitchen towel or paper towels. Trim off the woody ends by snapping them where they naturally break or cutting off the bottom 1 to 2 inches.
Place the asparagus spears on the prepared baking sheet in a single layer. Drizzle the olive oil evenly over the asparagus and use your hands or tongs to toss until every spear is lightly coated.
Spread the asparagus back into a single layer, making sure the spears aren’t piled on top of each other. This helps them roast and crisp instead of steam.
Sprinkle the grated parmesan evenly over the asparagus, covering as many spears as possible. Let some cheese fall onto the pan between the spears—that’s what turns into those crispy, golden cheesy bits.
Roast in the preheated oven for 10 to 14 minutes, depending on the thickness of your asparagus, until the spears are bright green, tender-crisp when pierced with a fork, and the parmesan is melted, golden brown, and crisp around the edges.
Remove the pan from the oven and let the asparagus sit for 1 to 2 minutes so the cheese can set slightly. Use a spatula to gently lift the spears and any crispy cheese from the pan onto a serving plate. Serve immediately while hot and perfectly cheesy.
Variations & Tips
For extra flavor without adding more ingredients, you can play with technique: roast the asparagus a minute or two longer for deeper browned, crispier cheese, or pull it out earlier if you like a softer bite. If you’re not strictly counting ingredients, a light sprinkle of black pepper or a squeeze of lemon juice right before serving brightens everything up. You can also adjust texture by changing how you grate the parmesan—finely grated gives a more even, lacy crust, while slightly coarser shreds create bigger, extra-crispy patches. For meal prep, trim and wash the asparagus the night before and store it wrapped in a paper towel in a zip-top bag in the fridge; then all you have to do on a busy evening is toss with oil, top with cheese, and roast. If you’re feeding a crowd, simply double the recipe and use two pans, rotating them halfway through so everything roasts evenly.
