Ina Garten Potato, Fennel & Gruyère Gratin. You'll Need: potatoes, onion, fennel bulbs, olive oil, butter, heavy cream, Gruyere cheese, salt, and pepper. Carrisa Says - used one large fennel bulb instead of two small. Turned out wonderful! Hubby loved it! Definitely a keeper. Variation to try: nix fennel and add 50:50 potatoes and rutabega, and add 2 cloves of garlic.
This rich, cheesy, nutty fennel gratin is peak comfort food. Like seriously we want to cuddle it in a fuzzy blanket or something. A little crunchy, a little soft; too soon to tell but this might be the only side dish you cook for the rest of your life.
Potato-Fennel Gratin - this is the best fall/winter side dish. Make it up to 2 days in advance and keep in the fridge - heat it in the oven before dinner. Make half of the recipe for just the two of you. I've even served this at brunch and with barbecue.
Nothing says warmth and comfort like a creamy gratin fresh out of the oven, golden brown and bubbling on top. From potato and pimento cheese to fennel, red cabbage, and even Brussels sprouts, warm up your table with one of these 14 easy vegetable gratin recipes.
