Instructions
- Prep the Cardoons:: First things first, those cardoons, hon! Wear gloves if you’re sensitive, they can be a bit prickly. Trim off the tough outer ribs and any stringy bits. Give them a good wash, then slice them into 1-inch pieces. Pop them into a pot of salted boiling water with a squeeze of lemon juice (this helps prevent browning) and cook until tender, about 15-20 minutes. I always taste one to make sure it’s just right. Drain them well; you don’t want any extra water making your gratin soggy.
- Slice and Layer Potatoes:: While the cardoons are doing their thing, thinly slice your Yukon Gold potatoes. A mandoline is a lifesaver here for even slices, but a sharp knife works too. My first time, I sliced them too thick, and they took ages to cook through. Don’t make my mistake! Grab a 9×13 inch baking dish and lightly butter it. Arrange a single layer of potato slices, slightly overlapping, at the bottom. This is where the magic starts to happen for your Cardoon Potato Gratin.
- Creamy Sauce Assembly:: In a saucepan, gently warm the heavy cream with minced garlic, a pinch of salt, and a good grind of black pepper. You don’t want it boiling, just warmed through and fragrant. This step is crucial for infusing flavor into the sauce. I usually let it simmer for a minute or two, letting those garlic notes really bloom. The smell is honestly intoxicating and gets me excited for the Cardoon Potato Gratin ahead!
- Build Your Gratin Layers:: Now for the layering! Sprinkle some of your cooked cardoon pieces over the first potato layer. Then, pour a ladleful of the warm cream mixture over the top, making sure to distribute the garlic. Sprinkle generously with grated Gruyère. Repeat these layers: potatoes, cardoons, cream, Gruyère, until all your ingredients are used up, ending with a layer of potatoes and Gruyère. I sometimes get a little messy here, but that’s part of the fun!
- Crispy Sage Topping:: In a small skillet, melt the butter over medium heat. Add the panko breadcrumbs and fresh sage leaves. Cook, stirring frequently, until the breadcrumbs are golden brown and crispy, and the sage is fragrant, about 3-5 minutes. This topping is a game-changer for the Cardoon Potato Gratin; it adds such a lovely textural contrast. Don’t walk away, though, panko burns quickly!
- Bake to Golden Perfection:: Cover your baking dish loosely with foil and bake in a preheated oven at 375°F (190°C) for 40 minutes. Then, remove the foil, sprinkle the crispy sage breadcrumbs over the top, and bake for another 20-25 minutes, or until the Cardoon Potato Gratin is bubbly, golden brown, and the potatoes are fork-tender. Let it rest for 10 minutes before serving. It’s hard, but it helps the gratin set!
