I recently tried making this Haitian-style gratin de pommes de terre au fromage, and it turned out to be a delicious comfort food that impresses every time. The key to achieving that creamy texture lies in the sauce, which blends sautéed garlic and onions with cream or milk, creating a rich base that seeps beautifully into the thin potato slices. One tip I found useful is to slice the potatoes as evenly and thinly as possible. This ensures they cook uniformly when covered and baked. After layering the potatoes with the creamy sauce, I cover the dish with aluminum foil (I used DIAMOND brand foil, which held up well) to keep moisture in during the initial cooking phase. Then, uncovering it in the last 15 minutes allows the cheese to brown and form that irresistible golden crust. Using a good melting cheese is essential. I often use a blend of cheddar and mozzarella for both flavor and a nice stretch. What makes this gratin stand out in Haitian cuisine is how the garlic and onions subtly infuse into every bite, enhancing the simple potatoes and cheese. If you enjoy scalloped or cheesy potatoes but want to try a Haitian twist, this recipe combines familiar comfort with unique flair. Plus, it’s straightforward enough for weeknight dinners but special enough to serve guests. Definitely save or 'enregistre pour ce soir' to make this flavorful dish soon!
