Whisk until smooth. Season with additional salt and pepper if desired.
6. Pour Sauce & Bake (Covered)
Slowly pour the cheese sauce over the casserole. Try to distribute evenly, letting it soak into the layers.
Cover the dish tightly with aluminum foil.
Bake in the preheated oven for 1 hour.
7. Uncover & Finish Baking
Remove foil.
Bake uncovered for an additional 15–20 minutes, until the cheese on top is golden brown and bubbly.
🔸 Note: If your potatoes are sliced thicker than ¼ inch, you may need to bake the covered portion an extra 15–20 minutes to ensure they’re fully tender.
8. Cool & Serve
Remove casserole from the oven.
Let rest for 5–10 minutes before slicing and serving. This allows the layers to set slightly and makes serving easier.
