Tips
Garlic is optional; omit if your family prefers milder flavor since kielbasa contributes its own garlic notes.
For extra-large potatoes, use a 9x11 inch casserole dish instead of the standard 7x11 inch.
Good to Know
Refrigerate covered up to 4 days. Reheat in oven at 350F until heated through.
Assemble casserole up to 8 hours ahead; cover and refrigerate, then bake when ready, adding 10-15 minutes to baking time if starting from cold.
Spoon directly from casserole dish. Serve with crusty bread or a simple green salad.
Common Mistakes
Do not skip placing casserole on a baking sheet to catch any overflow and prevent spills in oven.
Do not skip peeling potatoes unless you prefer the texture of unpeeled russet skins in this creamy dish.
Do not skip the 90-minute bake time; undercooked potatoes will be hard and will not absorb the cheddar sauce properly.
