Kangkong Gratin Recipe

Preheat oven to 375°F. Set oven to top heat or broil option.

Melt butter in a pan. Fry bacon for 1 minute. Add onions and garlic. Sauté until fragrant. Add mushrooms and sauté until cooked. Set mushroom mixture aside, leaving rendered fat in the pan.

Add flour to pan and cook for 2 minutes. Add milk, cream, nutmeg, and mushroom mixture. Bring to a boil.

Squeeze kangkong leaves to remove excess water. Add to pan and mix well. Add parmesan cheese. Season with salt and pepper.

Transfer mixture to a shallow baking dish. Sprinkle with Gruyère cheese. Bake in the preheated oven for 7 to 10 minutes or until top is golden and a crust forms on top.

Make ahead tip: Blanch the kangkong and prepare the cream sauce the night before, chill, and remove from refrigerator 10 minutes before cooking.
