📋 Ingredients and notes
To make this super easy asparagus casserole, you'll need unsalted butter, Panko breadcrumbs, asparagus, shallot, garlic cloves, all-purpose flour, whole milk, grated nutmeg, cream cheese, white cheddar cheese, and salt.
Notes and Variations
- Thickness of asparagus: You don't want the asparagus to be too thick or thin. For thick asparagus, then you can slice it in half for this recipe.
- Substitute Panko bread crumbs. If you're in a pinch and don't have any Panko bread crumbs, you can easily substitute them with Ritz cracker crumbs.
- Choice of cheese. For this easy recipe, I used cream cheese and cheddar cheese to give it a good mix of creamy and nutty flavors. You can also use mozzarella, Parmesan cheese, or any other grated cheese of your choice.
- Make it vegan. Substituting the butter, cream cheese and cheddar cheese with vegan variants (e.g., plant-based butter, vegan cream cheese and vegan cheddar shreds) means you can make this vegan super easily!
- Gluten-free. To make a gluten-free version of this recipe, simply replace the all-purpose flour with an alternative (e.g., tapioca, coconut flour, or rice flour) or cornstarch can all work to make a similarly creamy roux.
- Swap asparagus with other greens. This recipe works just as well with broccoli or green beans. So if you want to mix it up, or swap the veggies, you can totally do that.
📖 How to Make Asparagus Casserole
To make this creamy asparagus casserole, you need to preheat the oven to 450°F. Bring a pot of water to a boil over medium-high heat and set a bowl of ice water near the stove.
In a small bowl, melt the butter in the microwave for about 30 seconds. Stir in panko breadcrumbs and set aside.
Cook asparagus in boiling water for 1 minute, then transfer it to the ice bath. Once cooled, drain and pat dry for tender asparagus. Arrange the asparagus in a 9x9-inch baking dish.
In a medium pot, melt the remaining butter over medium heat. Add shallots to the melted butter and garlic, and cook until fragrant (about 1 minute). Stir in flour and cook for 30 seconds to get the creamy sauce started.
Gradually add milk and bring to a boil, whisking constantly. Cook for another 5 minutes or until thickened, remove from the heat and sprinkle nutmeg. Stir in cream cheese, cheddar, and salt. Pour the cheese sauce over the asparagus. You can add some black pepper as well if you wish.
Sprinkle the reserved panko mixture (or Ritz crackers) on top of the casserole. Bake for 12-15 minutes until asparagus is tender and sauce is golden brown.
👩🏽🍳Top Tips to Make Asparagus Casserole
Have all your guests raving about your asparagus casserole by following these five easy tips.
- Choose the best asparagus. Look for asparagus that is firm and has tightly closed tips. Limp stalks won't give you the right texture for a casserole! Choose fresh stalks with vibrant green and purple hues, versus paler or dull yellow-green ones. Avoid any with signs of wilting or dark spots, as these indicate the stalk is past its prime.
- Don't forget to blanch asparagus. I know it's an extra step, but blanching the asparagus before adding it to your casserole helps prevent the vegetable from becoming too soft in texture when baking. It also helps retain the vibrant color of the asparagus!
- Don’t overcook the asparagus. The trick is to steam it until it’s slightly tender but still crisp. Overcooked asparagus will become too soft and mushy when baked in the casserole dish!
- Play with toppings. Give your asparagus casserole an extra boost of flavor by swapping the toasted breadcrumbs or crushed crackers with fried shallots, or crunchy nuts. The topping will not only add a delightful crunch to an otherwise soft dish, but it’ll also give it some much-needed texture!
- Choose the right casserole dish. This ensures even baking and prevent burning or sticking. I use a 9x13 inch baking dish because it provides plenty of room for all of your ingredients but isn’t too large that everything gets lost in there.
Look for asparagus spears that are bright green with tight tips. The top of the asparagus should be firm to the touch, and not limp or rubbery. Avoid asparagus with woody ends or yellowed stalks – these are signs the asparagus has been sitting around a bit too long.
Honestly, it doesn't matter for this recipe! Each offers its own individual texture and flavor. However, keep in mind that thin asparagus will cook faster than their thicker counterparts—so depending on which you choose to use, be sure to adjust your cooking time accordingly.
Yes! This casserole is a great way to get your daily veggie intake. Packed with fresh asparagus, and cheese and topped with Panko bread crumbs, it's a nutritious and delicious meal. It's also easy to switch out ingredients or add in extra vegetables, making it even healthier!
🍴 Serving and storage suggestions
The easy asparagus casserole recipe can be made ahead of time. Just prepare the dish all the way until the baking step, cover it, and put it in the freezer for 3 months. When it is ready to be cooked, simply let it thaw a room temperature, preheat the oven and bake the dish. This makes it a great holiday side!
However, keep in mind that the toppings should not be included on the top of the dish when storing them as this may cause the dish to become soggy! For the best, crunchy finish, top it with the cracker crumbs right before baking.
To store, let the casserole cool to room temperature before transferring it to an airtight container in the fridge for up to 3 days. When you're ready to reheat, place the casserole in a preheated oven at 325°F until heated.
I don't recommend freezing cooked asparagus casserole.
