Step 3: Season Each Vegetable
Pour 4 tablespoons of cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Sprinkle each bowl with 1/2 ounce of grated Parmesan cheese and 1 teaspoon of minced thyme. Donβt forget a generous pinch of salt and a few cracks of black pepper. Toss each bowl until the veggie slices are well coated.

Overcrowding the dish: Packing too many vegetables in one layer can prevent them from cooking evenly. Aim for even layers and proper spacing for uniform cooking.
Not using enough cream: Using insufficient cream will lead to a dry gratin. Ensure you measure accurately and coat each layer for that creamy texture.
Underestimating baking time: Not allowing enough time for baking can result in crunchy veggies. Always check for tenderness and adjust baking time accordingly.
Forgetting the foil cover: Skipping the foil during the first bake may cause the cheese to brown too quickly. Cover your dish initially to ensure even cooking.
