My dear sister passed down this creamy 4 ingredient bake and it is pure comforting perfection for the season.

My dear sister first slipped this dish onto our holiday table sometime in the late seventies, right as the weather turned sharp and the fields around us went quiet. She called it her “creamy four-ingredient bake,” and it was exactly that: thin slices of potato and soft green cabbage tucked into a pretty casserole dish, drowned in rich cream and finished with a blanket of cheese. It’s the sort of simple, honest food that feels like a hug at the end of a long day—no fussy steps, just a warm, bubbling pan that perfumes the whole house. This oven baked 4-ingredients cabbage and potato gratin is perfect for the colder months, when you want something comforting, filling, and easy enough to pull together even when you’re tired. It’s a farmhouse kind of recipe, born from what we always had on hand and polished by years of family suppers.

Serve this creamy cabbage and potato gratin straight from the floral casserole dish while it’s still bubbling around the edges and the cheese is golden. It’s hearty enough to stand on its own with just a green salad or sliced tomatoes on the side, but it also makes a lovely partner for simple roasted chicken, pork chops, or a skillet of sausage. A basket of warm dinner rolls or buttered rye bread is perfect for soaking up the extra cream, and a side of tart applesauce or pickles adds a bright note against all that cozy richness.

Servings: 4-6

1 small head green cabbage (about 1 1/2 pounds), cored and thinly sliced

Preheat your oven to 375°F (190°C). Lightly grease a medium-sized casserole dish (about 2 to 2 1/2 quarts) with soft butter or a little oil. If you have a floral baking dish, now is the time to use it—this is a homey, table-ready kind of bake.

Prepare the vegetables. Peel the potatoes and slice them as thinly and evenly as you can, about 1/8 inch thick, so they cook through and become tender. Core the cabbage and cut it into thin shreds or ribbons. Keep the potatoes and cabbage in separate piles.

Season the cream. In a measuring cup or small bowl, stir the heavy cream with the salt and pepper. This simple step makes sure every layer gets a bit of seasoning without any extra fuss.

Build the first layer. Lay a single, overlapping layer of sliced potatoes over the bottom of the casserole dish. Scatter a generous handful of sliced cabbage over the potatoes, spreading it evenly but not packing it down too tightly.

Add cream and cheese. Spoon or pour a little of the seasoned cream over the potato and cabbage layer—just enough to lightly coat, not to drown it yet. Sprinkle a small handful of the shredded cheese over the top, focusing some around the edges where it will brown nicely.

Repeat the layers. Continue layering potatoes, then cabbage, then a splash of cream and a sprinkle of cheese, until you’ve used up all the vegetables. Aim to finish with a layer of potatoes on top. Pour any remaining cream evenly over the surface, letting it trickle down between the slices.

Top with cheese. Scatter the rest of the shredded cheese over the top layer of potatoes, making sure to cover the edges so they can bubble and brown in the oven. The top should look well blanketed but not overly thick with cheese.

Cover and bake. Cover the casserole dish loosely with foil, tenting it slightly so it doesn’t stick to the cheese. Place the dish on a baking sheet to catch any drips, and bake in the preheated oven for about 40 minutes, until the potatoes and cabbage are starting to soften and the cream is hot and steamy underneath.

Uncover to brown. Carefully remove the foil and return the dish to the oven. Bake, uncovered, for another 20–30 minutes, or until the top is deeply golden, the cheese is browned around the edges, and the cream is bubbling up between the slices. A knife should slide easily through the potatoes and cabbage with no resistance.

Rest before serving. Take the casserole out of the oven and let it rest for at least 10 minutes. This short rest allows the creamy sauce to settle and thicken slightly, so you can scoop out neat portions that show off the tender layers of potato and cabbage. Serve warm, straight from the floral dish, with those browned, cheesy edges proudly on display.

If you’d like the gratin a little lighter, you can use half-and-half instead of full heavy cream, though it won’t be quite as rich and may be slightly looser. My sister sometimes tucked in very thin slices of onion between the layers for extra flavor—if you do this, keep the amount modest so it doesn’t overpower the cabbage. You can also play with the cheese: a mix of cheddar and Swiss gives a deeper, nuttier taste, while all Monterey Jack keeps it very mild and creamy. For a bit of color and crunch on top, sprinkle a small handful of breadcrumbs over the cheese during the last 10–15 minutes of baking. If you need to make it ahead, assemble the dish up to the point of baking, cover tightly, and refrigerate for up to a day; add an extra 10–15 minutes to the covered baking time if it’s going in the oven cold. Leftovers reheat nicely in a moderate oven, covered with foil, until warmed through—the flavors often deepen by the next day, making it just as comforting for a simple weeknight supper as it was on the holiday table.
