This Sausage and Potato Casserole with Spring Veggies is my go-to when I want that nostalgic feeling of family gathering around something truly comforting. It brings together savory sausage, melting cheese, and the brightness of asparagus and potatoes for a dish that always makes the dining room feel extra cozy. If a homemade casserole is what you crave, you will love how easy and satisfying this one is.
My father-in-law asks for this casserole every visit and even the kids dive in for seconds. I tried this for a Sunday lunch one spring and it immediately earned a spot in our family favorites.
