Lemon Asparagus Casserole

READY IN: 40mins
Recipe by AshK5246

I love fresh asparagus, so I wanted to post some of our family's favorites. This is a great spring dish and is perfect for brunch or dinner! You can substitute a good quality Italian bread crumb mixture for the topping (still mixed with the canned fried onions).

This made a light dinner for us last night. I halved the recipe and used an 8x8 baking dish without trouble. I doubled the amount of lemon zest but still didn't notice a prominent lemon flavor. I also subbed out the heavy cream for milk and added a little corn starch to thicken the sauce. The topping was very yummy!
