5. After each layer, sprinkle cheeses and drizzle some cream mixture.

6. Repeat until all ingredients are used.

7. Finish top layer with remaining cheese and thyme.

Allow to come to room temp before baking.

Substitute with Yukon gold potatoes or carrots if desired.

Ensure cheese is rennet-free to keep it vegetarian.
