Ingredients

Instructions

  1. Step 1: Preheat oven to 180°C (350°F). In a large oven-safe dish, layer 1/3 of the diced potatoes, 1/3 of the grated Orval cheese, and 1/3 of the chopped bacon. Repeat layers, finishing with a layer of potatoes and a drizzle of heavy cream.
  2. Step 2: In a saucepan, melt 50g butter over medium heat. Add chopped onion and sauté for 3-4 minutes until translucent. Stir in 200ml Trappist beer and 1 tsp thyme. Simmer for 10 minutes until reduced by half, then pour evenly over the gratin layers.
  3. Step 3: Bake for 40-45 minutes until the top is golden and the potatoes are tender. Let rest for 10 minutes before serving.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep grated orval cheese from drying out.

Can I substitute ingredients in Orval Cheese and Trappist Beer Gratin?
