Ingredients in Potato-Rutabaga Gratin with Gruyère

Here’s what makes this gratin truly magical it’s humble ingredients coming together for maximum flavor and comfort:

Potatoes: Yukon Gold or russet potatoes work beautifully. They’re tender, buttery, and soak up all that creamy goodness.

Rutabaga: Slightly sweet, a bit earthy, and a perfect partner to potatoes. It adds dimension and a subtle complexity.

Heavy Cream: Rich, silky, and the base of that luscious gratin sauce. It creates a velvety texture you’ll swoon over.

Gruyère Cheese: Melty, nutty, and a little fancy. Gruyère melts into every crevice and gives the dish that irresistible golden crust.

Butter: Used for greasing and a little dotting on top, butter makes everything better—especially in a gratin.

Salt and Pepper: Essential to bring out the flavor of each vegetable layer. Season well!

Optional Extras: Fresh thyme, garlic, or even a little pinch of nutmeg if you want to amp up the cozy factor.

Instructions

Let’s dive into the steps to create this flavorful masterpiece:

Preheat Your Equipment

Start by preheating your oven to 375°F (190°C). This ensures your gratin cooks evenly and gets that beautiful golden top.

Prepare the Baking Dish

Butter your baking dish generously. This keeps the gratin from sticking and adds a layer of rich flavor.

Slice the Vegetables

Using a mandoline or a sharp knife, thinly slice the potatoes and rutabaga into even rounds. Consistent thickness helps them cook uniformly and stack beautifully.

Layer the Gratin

Start layering the potato and rutabaga slices in the dish, overlapping slightly like shingles. Sprinkle each layer with a bit of salt, pepper, and a generous handful of grated Gruyère.

Add the Cream

Once the layers are set, pour the heavy cream evenly over the top. It’ll sink into all the nooks and crannies and create that dreamy texture we’re going for.

Top and Dot

Add a final layer of Gruyère on top, then dot with a few small pieces of butter for extra golden bubbling magic.

Cook to Perfection

Cover the dish with foil and bake for 45 minutes. Then remove the foil and bake for another 20–25 minutes, or until the top is deeply golden and the vegetables are tender when pierced with a knife.

Finishing Touches

Let the gratin rest for 10–15 minutes after baking. It’ll set up nicely and make for easier slicing and even better flavor.

Serve and Enjoy

Scoop generous portions onto plates and watch them disappear! Creamy, cheesy, and just a little crispy on top it’s pure gratin bliss.
