Zucchini and sweet potato gratin

Ingredients for 4 servings:

• 450 g zucchini
• 350 g sweet potatoes
• 125 g ham (chicken ham, round slices)
• 200 ml sour cream
• 80 ml milk
• 1 tbsp extra virgin olive oil
• 100 g grated cheese (Emmental, Mozzarella, Gouda)
• Herb salt and pepper, freshly ground
• 2 pinches of turmeric powder

Instructions

Working time approx. 10 minutes; Cooking/baking time approx. 50 minutes; Total time approx. 1 hour

for the Omnia oven

Wash the zucchini. Cut off the stem and flower end and slice the zucchini into slices about 2 mm thick using a slicer. Peel the sweet potato and also slice it into slices about 2 mm thick. Drizzle the olive oil into the Omnia. Now alternate slices of zucchini, ham, and sweet potato in the dish. I always placed the chicken ham between two zucchini slices. There is enough to place the slices vertically in the dish. Mix the sour cream with the milk, grated cheese, herb salt, pepper, and turmeric powder. Pour the mixture over the slices. Place the dish on top of the gas stove, set it on the lowest heat, and bake for 10 minutes on high, then reduce the heat to about half the heat and bake for another 40 minutes. Tip: The gratin can also be prepared in the regular oven. Bake at 185 degrees Celsius for about 40-45 minutes. For a larger baking dish, arrange the slices in the oven like roof tiles.
