FAQs
Can I make Sausage & Guinness Gravy Casserole ahead of time?
Yes, you can assemble Sausage & Guinness Gravy Casserole up to one day in advance. Simply layer the potatoes and pour the sausage and Guinness gravy over the top, then cover and refrigerate. When you are ready to bake, let the dish sit at room temperature for about 20 minutes. Then bake as directed, adding a few extra minutes if needed. This method makes it perfect for busy holidays like St. Patrick’s Day.
Can I turn this into a crockpot meal?
You can adapt Sausage & Guinness Gravy Casserole for slow cooking by layering everything in a greased crockpot. Cook on low for 6 to 7 hours or until the potatoes are tender.

What can I serve with Sausage & Guinness Gravy Casserole?
This casserole pairs well with a simple green salad or steamed cabbage to balance the rich gravy. You can also serve it with crusty bread to soak up every bit of sauce.
