How to Properly Trim Asparagus

Before we start assembling the casserole, let’s cover off on the proper way to trim your asparagus spears.

• Clean the Asparagus: Hold the asparagus under cool water and give it a good rinse.
• Trim the Asparagus: Next, slice off the woody, lighter-colored ends of each stalk. Alternatively, you can bend the stalks until the woody ends snap right off.
• Dry the Asparagus: Use a kitchen towel to pat the asparagus dry of any excess moisture. Season and dice as you wish!

Preparing this Easy Asparagus Casserole Recipe

Whipping us this asparagus casserole starts with a simple, savory cream sauce and ends with a quick bake in the oven.

• Make the Sauce: In a heavy bottom saucepan, melt the butter with the heavy cream and bring it to a simmer. Whisk until well-combined. Next, add in 1 cup of the parmesan cheese (you’ll save the rest for the top!), garlic parsley salt, and minced garlic. Stir the sauce until it’s smooth and creamy.
• Prep the Asparagus: Next, trim the asparagus and slice into 2-inch pieces.
• Assemble the Casserole: Place the asparagus evenly throughout a baking dish and pour the sauce on top. Sprinkle on the rest of the parmesan cheese and top with the panko breadcrumbs.

Pro Tips for the Best Asparagus Casserole

A couple pro tips will help you get the most out of this asparagus casserole.

• Cook the sauce on a medium simmer. To avoid burning the sauce, cook it over medium heat until it’s smooth and creamy.
• Pull the casserole out once it’s fork tender. If you’re unsure if your casserole is ready, test the asparagus with a fork. If you can easily pierce it, it’s good to go!
• Put the casserole under a quick broil for a crispier top. If you want an extra crispy top, pop the casserole under a quick broil (2-3 minutes).
• Experiment with different seasonings. Asparagus is one of the most versatile vegetables, so feel free to tweak the casserole with a bit of freshly cracked black pepper, caramelized onions, or even smoked paprika.

Ways to Serve Asparagus Casserole

This asparagus casserole is a great side dish to your favorite protein. A leg of lamb or cast-iron ribeye immediately come to mind. If you want to make it a one-pan meal, add in some Instant Pot chicken for protein.

Storing & Reheating Tips

Asparagus casserole is great for a make-ahead side dish or leftovers. Here’s all you need to know about storing and reheating it.

• Storing: To keep the casserole on hand for up to 5 days, keep it in an airtight container in the fridge.
• Reheating: The best way to reheat the casserole is back in the oven at 350°F covered with aluminum foil for about 10 minutes. At the very end, remove the foil and cook the casserole uncovered for a couple of minutes until the top crisps up again.
