Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a large baking dish with butter or olive oil.
Step 2: Prepare the Potatoes
- Slice the Potatoes: Thinly slice the potatoes using a sharp knife or mandolin slicer. You want them thin enough to cook evenly but thick enough to hold their shape, about 1/8-inch thick.
- Layer in the Baking Dish: Arrange a layer of potatoes on the bottom of the prepared baking dish, overlapping the slices slightly.
Step 3: Sauté the Vegetables
- Heat the Olive Oil: In a large skillet, heat 2 tbsp olive oil over medium heat.
- Add Onions and Garlic: Sauté the onion and garlic until softened, about 3-4 minutes.
- Add Mushrooms, Bell Peppers, and Zucchini: Add the sliced mushrooms, bell pepper, and zucchini to the skillet. Cook for another 5-6 minutes, stirring occasionally, until the mushrooms release their moisture and the vegetables begin to soften.
- Season: Stir in thyme, smoked paprika, salt, and pepper to taste.
Step 4: Layer the Vegetables and Potatoes
- Layer Vegetables Over Potatoes: Once the vegetables are sautéed, spread a layer of the vegetable mixture over the sliced potatoes in the baking dish.
- Repeat the Layers: Continue alternating layers of potatoes and vegetables until you’ve used all the ingredients, finishing with a top layer of potatoes.
Step 5: Prepare the Creamy Sauce
- Make the Sauce: In a small saucepan, warm heavy cream over low heat, just until heated through (don’t let it boil). Stir in half of the shredded mozzarella and Parmesan cheeses.
- Pour Over the Bake: Slowly pour the creamy cheese sauce evenly over the layered potatoes and vegetables, allowing it to seep into the layers.
Step 6: Bake
- Cover and Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes.
- Remove Foil: After 45 minutes, remove the foil, sprinkle the remaining mozzarella and Parmesan cheeses over the top, and bake uncovered for an additional 15-20 minutes, or until the cheese is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
Step 7: Garnish and Serve
- Garnish: Once out of the oven, let the bake cool for a few minutes, then sprinkle with freshly chopped parsley for a burst of color.
- Serve: Slice into portions and serve warm. This dish pairs wonderfully with a crisp salad or some garlic bread on the side.

Tips for the Best Results
- Use a Mandolin Slicer: To get evenly thin slices of potatoes, use a mandolin slicer for consistency.
- Parboil Potatoes: If you’re short on time, parboil the sliced potatoes for 5-7 minutes before layering them in the dish to speed up the baking process.
- Extra Crispy Top: For a crispy, golden top, broil the bake for the last 2-3 minutes of cooking, but keep an eye on it to prevent burning.
