Years ago, I was on the phone with my mom when she said abruptly, "Just a second, there's a recipe I want to read to you." She had just re-discovered a pumpkin cookbook that dated back to her newlywed days and wanted to share a little of her culinary history with me.
The recipe my mom narrated that day was for a dish of pumpkin, potato, cheese and egg, all mashed together and baked in a casserole dish. I took notes as she talked and a day or so after we hung up, headed into the kitchen to update the recipe.
I used Yukon gold potatoes and butternut squash and scattered thin ribbons of fresh sage throughout. It is rich, brightly flavored and makes for an excellent holiday or potluck dish. I start thinking of it hungrily every autumn and find a reason to make it at least once a year. It also taught me to listen intently every time my mother announces she has a recipe to share.
1 cup shredded gruyere
1/2 cup shredded parmesan
2 pounds of butternut squash, peeled and cubed
2 pounds of potatoes, peeled and quartered
2 tablespoons butter
1 tablespoon minced sage leaves (about 6-8 leaves)
