    Gently pour the prepared cream mixture over the top and spread evenly.

  8. 8

    Sprinkle the shredded cheese evenly over the top.

  9. 9

    Bake for 30-35 minutes until the surface is golden brown and the potatoes are fork-tender.

  10. 10

    Remove from the oven and let rest for 5 minutes before serving hot.

💡 Chef's Tip

For an extra crispy crust, finish the gratin under the broiler for 2-3 minutes. Chef's tip: remove excess moisture from the potatoes by drying them with a kitchen towel after slicing—this will make your gratin creamier. You can prepare the gratin 2 hours before baking and keep it in the refrigerator.
