Meet Cheesy Boulangère Potatoes, Creamier Than Gratin and Better Than Any Casserole
French potato Boulangere goes luxe: processed cheese turns the classic into a creamy showstopper.
Classic French Boulangere potatoes are the definition of humble: thin potato slices, onion, milk, butter. I nudge it closer to gratin territory by slipping in processed cheese, which melts into a glossy, velvety sauce. Minimal fuss, major payoff.
What you need
- Potatoes - 1 kg
- Yellow onions - 2
- Butter - 60 g
- Milk - 400 ml
- Processed cheese (briquettes/blocks) - 150–200 g
- Garlic - 2 cloves
- Salt and black pepper - to taste
How to make it
Slice the potatoes as thinly as you can manage, about 2 mm. Cut the onions into thin half-moons. Lightly crush or mince the garlic. Use a little of the butter to grease a baking dish, then melt the rest for finishing later.
Build the layers: a shingle of potatoes first, then a scatter of onion, a pinch of garlic, and small bits of processed cheese tucked here and there. Season each layer with a little salt and pepper as you go. Repeat this 2–3 times, finishing with a final layer of potatoes on top.
Warm the milk gently until just hot to the touch. Pour it down the sides of the dish so it seeps through the layers. Stop when the level sits just below the top layer of potatoes. Drizzle the melted butter over the surface.
Cover the dish with foil and bake at 200°C for about 40 minutes. Remove the foil, lower the oven to 180°C, and continue baking for another 35–40 minutes, until the top turns golden and the edges look a little caramelized.
What you get
The potatoes drink up the milk and butter, the onions mellow into gentle sweetness, and the processed cheese melts into a creamy, almost saucy texture. The result feels richer and silkier than a standard potato casserole, and frankly, a little more indulgent than a classic gratin.
