Tender asparagus spears baked under a creamy, savoury Parmesan topping with a hint of garlic and a pop of paprika. This Parmesan roasted asparagus takes just five ingredients and 25 minutes, and it might become your new favourite way to eat your greens.
Let’s talk about the topping, because it’s a little unexpected. A thin layer of mayonnaise gets spread over the asparagus, then showered with Parmesan, garlic powder and paprika. In the oven, it turns into a rich, golden, savoury coating, a bit like a cheesy gratin, that clings to every spear.
Underneath, the asparagus cooks until tender with just a little bite. It’s creamy, cheesy, garlicky and fresh all at once, and it’s so easy you’ll find yourself making it every week.
Serve it for Easter dinner, alongside a holiday roast, or with any weeknight chicken or fish.

Parmesan cheese – Adds a nutty, salty flavour and turns golden in the oven.
Garlic powder and paprika – Simple seasonings that add flavour and colour. Smoked paprika adds a lovely smoky note.
Step-by-Step Guide to Making Parmesan Roasted Asparagus
1. Prep the asparagus
Heat the oven to 350°F. Trim off the tough, woody ends, then lay the spears in a lightly greased 9×13 baking dish.
2. Add the topping
Spread the mayonnaise over the asparagus, then sprinkle evenly with the Parmesan, garlic powder and paprika.
3. Bake
Bake uncovered for 20 to 25 minutes, until the asparagus is tender and the topping is golden. Thinner spears will be done sooner.

Tips for the Best Roasted Asparagus
- Trim the woody ends: they’re tough and stringy.
- Match the thickness: similar-sized spears cook evenly.
- Spread the mayo thinly: just enough to coat.
- Check thin spears early: they cook faster.
- Serve straight away: the topping is best warm.
Common Mistakes to Avoid
- Leaving the ends on: the bottom of the stalk is too tough to eat.
- Overcrowding the dish: keep the spears in a single layer.
- Overbaking: asparagus goes limp. Pull it while it still has a little bite.
- Mixing thick and thin spears: the thin ones overcook.
Easy Ways to Change It Up
