I make Ina Garten’s easy potato gratin for my family every Christmas, and it’s the best holiday side dish

• I make Ina Garten’s potato-fennel gratin every Christmas.
• I first made it when I barely knew how to cook, and the easy recipe was 100% foolproof.
• The dish is cheesy and comforting and pairs perfectly with any holiday side dish.

There’s one “Barefoot Contessa” recipe I make for my family every Christmas, and I think it deserves a spot on everyone’s holiday menu.

I originally found Ina Garten’s recipe for potato-fennel gratin on the Barefoot Contessa website, but it also appears in her first cookbook, “The Barefoot Contessa Cookbook.”

“I love to make potato gratin and fennel gratin, so I decided to combine the two,” Garten writes in the description. “If you make this in an old French gratin dish, it looks wonderful and can go from the oven to the table with style.”

I started making Garten’s potato-fennel gratin when I had almost zero cooking skills, so I can attest that it’s 100% foolproof. More importantly, it’s incredibly comforting — and goes well with nearly everything.

Here’s how to make it.
