- This asparagus casserole recipe needs only 5 minutes of prep time and goes with any ham, turkey, chicken, or fish entrée!
Ingredients & Variations
Asparagus – Frozen asparagus is pre-cut to bite-sized pieces so prep is quick and easy! If using fresh asparagus, trim the woody stems from the bottoms and cut spears into 2”-3” inch pieces before using.
Sauce – A can of cream of mushroom soup makes this dish extra creamy and savory. Make a homemade mushroom sauce with basic ingredients, if you like.
Cheese – Cheddar and asparagus are a perfect pair! But you can try shredded Monterey Jack, Colby, or Swiss cheese in this recipe.
Crispy Fried Onions – Keep a can of crispy onions on hand to add crispy flavor to salads, soups, and burgers! Bacon bits are a great substitute if fried onions aren’t available.
Variations – Stretch the recipe by adding leftover cooked rice or meat like sausage or diced ham. A small bag of mixed veggies, water chestnuts, or sliced mushrooms will make a new dish every time!
How to Make an Asparagus Casserole
Simple, delicious, and perfect in every way!
- Cook asparagus in water until tender crisp.
- In a bowl, combine asparagus, soup, ½ of the cheese, milk, soy sauce, and 1 cup of crispy onions.
- Spread mixture in a casserole dish and bake (per recipe below).
- Top with remaining cheese and crispy fried onions and bake until golden.
Tips for a Creamy Casserole
Asparagus pieces can be simmered in vegetable or chicken broth in Step 2 for a richer flavor.
Milk can be switched out for any non-dairy product, with oat milk being the closest to getting a creamy consistency.
Once the casserole is baked, let it set for about 5 minutes before serving.
Leftovers
Keep leftover asparagus casserole covered in the refrigerator and reheat on the stovetop or in the microwave with a little milk stirred in to loosen the cheesy sauce. Enjoy leftover asparagus casserole as a hearty breakfast with a fried egg on top and some bacon crumbles!
