FAQs

Can I use uncooked sausage instead of smoked?

Yes, but be sure to cook it thoroughly before adding to the slow cooker.

What kind of potatoes work best?

Yukon Gold or Russet potatoes are ideal for their texture and flavor when slow-cooked.

Do I need to peel the potatoes?

Peeling is recommended for a smoother texture, but you can leave the skin on if preferred.

Can I prepare this the night before?

Yes, layer the ingredients in the slow cooker insert, cover, and refrigerate overnight. Start cooking the next day.

Is it necessary to sauté the sausage first?

Not required, but it enhances flavor and improves texture by caramelizing the edges.

How do I keep the potatoes from becoming mushy?

Slice them evenly and avoid overcooking. Cooking on low gives the best texture.

Can I make it vegetarian?

Yes, use a plant-based sausage and cream of mushroom soup instead of chicken.

What can I use instead of cream soup?

Make a homemade white sauce with butter, flour, milk, and seasonings.

How can I thicken the casserole?

If too runny, remove the lid for the last 30 minutes of cooking to let excess moisture evaporate.

Can I double the recipe?

Yes, but use a large slow cooker (at least 6–7 quarts) and add 30–60 minutes to the cook time.
