Scalloped Root Vegetables and Leeks Gratin

Published on November 18, 2021

Since learning that root vegetables are full of fiber and very good for our guts, I have made a point of eating a lot of roots both raw and cooked. A recipe in a magazine for “Leeks and Root Vegetable Gratin” caught my eye and I had cut it out and had it on my desk to try. But when I looked at it closer this week I saw that it was just layers of the sliced roots and leeks with some cheddar cheese and herbs in between the layers. That’s it. No liquid. Maybe it would be great but I’ve had a lot of recipes go wrong, even ones in magazines, and this sounded like it could be dry. But I loved the sliced root vegetable and leeks idea so I borrowed that part and then did my own thing and was very pleased with the result.

The roots all blend in flavors very well. It was a surprising much lighter dish than scalloped potatoes with a lovely sweet taste. I think chicken broth will work in place of the cream and I’m planning to give that a go next time.

The root vegetables need to weight 3 pounds total after they are trimmed and peeled.


Saute the leeks in the butter for 5 minutes. Place the slices of vegetables into a large bowl. Mix the salt, pepper and sage into the cream and pour over the vegetables. Mix until all the pieces are coated then set the pieces flat in a 9″ by 13″ casserole. Cover with foil and bake in a 350 degree oven for 50 minutes. (If the vegetables come all the way to the top of the casserole, place a piece of foil under the casserole in case the cream spills over the sides.) After 50 minutes, check for tenderness with a fork. Remove the foil and sprinkle with the cheese and the parsley. You can set the oven for 400 degrees and put the casserole back in the oven uncovered for 15 minutes until the cheese melts and starts to brown or it’s a lot faster to run it under the broiler until the cheese is bubbling and turning golden brown. Make sure you watch it because it can burn under the broiler very quickly.
