• Grate the Cheddar and Parmesan cheeses into a bowl. If you prefer a finer grate, you can also use a food processor.
4. Layer and bake:
• Grease a casserole dish with a little butter to prevent the potatoes from sticking.
• Layer the potato slices in the casserole dish, distributing the layers evenly. Then pour the cream sauce evenly over the potatoes.
• Generously sprinkle the grated Cheddar and Parmesan cheeses over the potatoes. Make sure the cheeses are well covered.
5. Baking:
• Place the casserole in a preheated oven (180°C/350°F, conventional oven setting) and bake for about 30-40 minutes, until the potatoes are tender and the cheese is golden brown and crispy. You can test if the potatoes are cooked through with a fork – they should pierce easily.
6. Garnish and Serve:
• After baking, remove the casserole from the oven and garnish with some fresh thyme. Then cut into portions and enjoy!
Tips:
• Variation: For an even creamier texture, stir some cream cheese into the cream sauce.
• Herbs: In addition to thyme, you can also use rosemary or oregano to give the dish a different flavor.
• Spice: For an extra kick, stir some paprika or chili flakes into the cream sauce.
