Table of Contents
If you have some picky eaters in your house or people who ‘don’t like vegetables’ or aren’t fond of asparagus, I can almost guarantee they will like it when it’s roasted with red onions and covered with cheese.
Take advantage of springtime asparagus while you can. This is a perfect fast and easy side dish that’s ready in 20 minutes.
Or if you’re like me and love both roasted vegetables + cheese, then this is a meal unto its own. Low carb and naturally gluten-free, the asparagus is crisp-tender, the red onion imparts extra flavor, and the cheesy is ooey and gooey.

- Shredded mozzarella cheese

Can I Use Another Type of Cheese?
Of course! Use whatever shredded cheese you think would pair nicely with oven baked asparagus.
How to Make Cheesy Asparagus
- Preheat your oven to 425ºF, then line a baking tray with foil.
- Add the trimmed asparagus and sliced onions to the baking tray, drizzle with oil, and season with salt and pepper. I like to use my hands to distribute the oil evenly.
- Roast the asparagus until crisp-tender.
- Sprinkle with cheese and return to the oven until the cheese is melted.
Recipe Tips
Seasoning: I seasoned my cheesy baked asparagus simply with salt and pepper, but you’re welcome to use your favorite seasoning blend instead.
Bake time: Be careful not to over cook the asparagus in the oven. You want the asparagus to retain some of its bite, otherwise it’ll turn to mush.
Browning the cheese: You can either roast the asparagus normally after you’ve sprinkled on the cheese, or you can pop it under the broiler if you prefer your cheese to be more golden browned rather than simply just melted. If you’re using the broiler, keep a very close eye on things since food can burn very quickly under the broiler.
Storage and Reheating Instructions
Roasted asparagus with cheese is best enjoyed right away. However, leftovers will keep in the fridge for up to 5 days.
I recommend reheating the asparagus in a 350ºF oven for 5 to 8 minutes. Reheating it in the microwave will make it go soggy.

Cheesy Roasted Asparagus
Ingredients
- one bunch asparagus, trimmed
- ½ of one medium red onion, sliced vertically into thin strips
- 2 tablespoons olive oil
- 1 teaspoon kosher salt
- 1 teaspoon freshly ground black pepper
- 1 ½ cup shredded mozzarella cheese
Instructions
- Preheat oven to 425F. Line a baking sheet with foil for easier cleanup.
- Add the asparagus and onions to the baking sheet, evenly drizzle with olive oil, evenly sprinkle with salt and pepper, and use your hands to toss to coat evenly.
- Bake for about 12 to 15 minutes, or until asparagus is crisp-tender.
- Remove baking sheet from the oven, evenly sprinkle the cheese over middle section of the asparagus, and return the baking sheet to the oven for about 5 minutes, or until cheese has melted.
- Alternatively, place the baking sheet under the broiler on high for about 3 to 4 minutes if you prefer your cheese to be more golden browned rather than simply just melted. If you’re using the broiler, keep a very close eye on things since food can burn very quickly under the broiler.
- Recipe is best warm and fresh.
