- Maple syrup: this adds sweetness to the dish.
🎯 TFN Pro Tip
Keep your asparagus fresh.
To keep your asparagus fresh and tender, store the stalks upright (woody ends down) in a tall glass or jar with 1 inch of water in the bottom for 1-2 days. Cover with plastic wrap.
Asparagus Casserole Recipe Tips For Success
- Cut off the ends of the asparagus.
To begin, lay the asparagus flat on a cutting board and align the tips of the spears. Use a chef’s knife to cut off the bottom inch of the woody ends straight across.
This part is woody and hard to chew, so cutting it off ensures each bite is tender.
- Poke holes in the asparagus with a fork.
Next, use a fork to poke holes in the stalks, allowing steam to escape, so they cook more quickly.
Save This Recipe!
- Whisk the egg white and maple syrup in a separate bowl.
Whisk together the egg whites and maple syrup in a separate bowl using a fork. This will allow all the ingredients to be evenly mixed before brushing on top of the dish.
- Lay the asparagus neatly in a casserole or baking dish and bake.
Next, spread the asparagus in the dish with the stalks all facing the same direction for a beautiful presentation.
Brush the egg wash over the top, sprinkle with the parmesan cheese, and then bake until the asparagus gratin is perfectly cooked and golden brown on top.
Serving Suggestions
This cheesy asparagus casserole recipe is perfect for a weeknight dinner. Serve it with cream of mushroom soup or grill some beef as a main dish. You can also add cheddar cheese or mozzarella cheese for extra cheesy casserole. Make some french-fried onions or deviled hard-boiled eggs as appetizers with this dish. Make this for Christmas, Thanksgiving, or Easter potluck.
Recipe FAQs
If the asparagus is mushy, it’s probably because it was overcooked. You can check to see when the asparagus is perfectly cooked by poking a fork through the stem. It should have a slight resistance but easily pierce all the way through.
Want that beautiful golden brown crusty cheese on top? No problem! Just pop it directly under the broiler right before removing the dish from the oven. Keep a close eye on it, though, since it can burn quickly – no more than a minute or two.
This baked asparagus is packed with flavors, thanks to the parmesan cheese and maple syrup. There is not a bland spear in sight!
Store leftover baked parmesan asparagus in an airtight container in the refrigerator for up to three days.
We don’t recommend freezing cooked asparagus as it becomes mushy and stringy when reheated.

Parmesan Asparagus Casserole
Ingredients
- Cooking spray
- 2 pounds thick asparagus trimmed (see notes below)
- 1 teaspoon salt
- 1 ½ cups parmesan cheese grated (3 ounces)
- ¾ cup panko bread crumbs
- 1 tablespoon butter melted
- 1 large egg white
- 1 tablespoon maple syrup
Optional
- sprigs of fresh thyme
Instructions
- Preheat oven to 450ºF. Spray the casserole dish with cooking spray.
- Use a fork to poke holes in the asparagus spears (the tough, woody portion) to help tenderize them during baking. Rinse well and then lightly sprinkle with salt and let sit while you prepare the topping.
- In a medium bowl, stir together 1 cup of parmesan, panko bread crumbs, and melted butter (set the other 1/2 cup of parmesan aside).
- Use a small bowl and fork to whip the egg whites and maple syrup until frothy.
- Add asparagus to the baking pan. About half should fit in a single layer. Brush with egg whites and maple syrup, then sprinkle with half of the panko topping. Add the rest of the spears on top and repeat the process with the rest of the egg white mixture and remaining panko mix.
- Bake for 6-7 minutes, until light golden on top. Sprinkle on the last 1/2 cup of parmesan cheese and bake another 6-7 minutes until the cheese is melted and the panko is golden brown. To check for doneness, use a paring knife to pierce a spear – if it goes in easily, the casserole is done.
- Top with sprigs of fresh thyme (optional).
