The first time I tasted LongHorn Steakhouse’s Parmesan Crusted Asparagus, I knew I had to recreate it at home. It was one of those appetizers that had everyone at the table reaching for more, even those who typically avoided vegetables. The crispy, cheesy coating transformed ordinary asparagus into something extraordinary, crunchy on the outside, tender on the inside, and bursting with savory Parmesan flavor.
After several test batches in my kitchen, I finally perfected this copycat recipe that captures all the magic of the restaurant version. Now it’s become my go-to dish for everything from dinner parties to family meals. What began as a restaurant appetizer has evolved into a versatile side dish that pairs beautifully with steaks, chicken, or even as a stand-alone vegetable option for those looking to add more greens to their diet. The best part? It’s surprisingly simple to make at home with ingredients you likely already have in your pantry.

Ingredients needed for Longhorn Steakhouse Parmesan Crusted Asparagus
- Fresh asparagus – Provides the tender, flavorful base that gets transformed by the coating; medium spears work best as they hold up to battering and frying
- All-purpose flour – Creates the foundation for the crispy coating and helps the Parmesan adhere to the asparagus
- Parmesan cheese – Contributes rich, savory flavor and golden-brown color when fried
- Seasoned salt – Adds the perfect blend of salt and spices that enhances the natural flavor of the asparagus
- Buttermilk – Acts as the binding agent that helps the flour and Parmesan stick to the asparagus; also adds tangy flavor
- Oil for frying – Creates the hot cooking environment needed for the perfect crispy exterior (canola or vegetable oil recommended)
- Shaved Parmesan – Optional garnish that adds visual appeal and an extra burst of cheese flavor

Ingredient notes
You can also choose to use two types of Parmesan:
- Grated Parmesan. I don’t often say this, but the pre-grated kind works just fine for this recipe.
- Shaved Parmesan. This is optional for the garnish because you can sprinkle grated parmesan on the finished dish. You can either get a block of Parmesan and shave off thin slices or get it already shaved.
Storage and Reheating Instructions
Storing Leftovers:
- Allow to cool completely before storing

I recommend placing the asparagus into a 350°F air fryer and cooking for 6 to 8 minutes. You can also reheat this in the oven at 350°F for about 10 to 12 minutes.

Can you bake this in the oven? I don’t really like fried foods and don’t own an air fryer.
I think if you have an air fryer or your oven has the convection option, this would be a good alternative.
Looks delicious! I can’t wait to try it.
