Step 1: Parboil the potatoes
- Bring a large saucepan of salted water to a boil. Add the thinly sliced potatoes and cook for about 5 minutes until they are just tender but not fully cooked. Drain the potatoes and set them aside.
Step 2: Prepare the cream mixture
- In the same saucepan, add the cream, milk, garlic, and thyme. Stir gently over medium heat for 2-3 minutes to infuse the flavors. Season with salt and pepper to taste.
Step 3: Combine the potatoes and cream
- Gently fold the parboiled potatoes into the cream mixture, making sure they are fully coated in the sauce. Be careful not to break the potato slices.
Step 4: Assemble the dish
- Preheat your oven to a high broil. Transfer the creamy potato mixture into an ovenproof dish, spreading it out evenly. Sprinkle the grated cheese over the top for a crisp, golden finish.
Step 5: Broil the potatoes
- Place the dish under the broiler for about 5 minutes or until the top is golden brown and bubbling. Keep a close eye on it to avoid burning.
Step 6: Serve and enjoy
- Once the Jamie Oliver Dauphinoise Potatoes are golden and bubbly, remove from the oven and let them sit for a few minutes before serving. Garnish with a little extra thyme if desired.
