For an extra touch of elegance, pipe the potato mixture into decorative swirls before baking. Ensure potatoes are thoroughly drained and dried to prevent a soggy casserole. Feel free to experiment with different herbs and cheeses to customize the flavor profile.

Jun 30, 2025I didn't have Boursin cheese on hand, so I used a mixture of cream cheese, garlic powder, and dried herbs. It was still amazing!

Jun 7, 2025My potatoes were a little watery after boiling, so I made sure to really dry them out in the pot before mashing. Worked perfectly!
