👨🍳 Step-by-Step Instructions
Boil the Potatoes
Place the peeled potatoes in a pot of salted water, bring to a boil, and cook for 18–20 minutes until completely fork-tender. Drain thoroughly and set aside.
Brown the Sliced Mushrooms
Heat the oil in a large deep skillet over medium-high heat. Add the sliced mushrooms and sauté undisturbed for 3–4 minutes, then stir occasionally for another 5–6 minutes until deeply browned and caramelized.
Sauté Onions & Rice
Add the finely chopped onion to the mushrooms and cook for 4–5 minutes until soft and translucent. Stir in the rinsed long-grain rice, seven-spice, black pepper, and salt, tossing for 1 minute to toast the grains.
Simmer Rice & Fold Fresh Herbs
Pour in the boiling water (or broth) and bring to a gentle boil. Cover tightly with a lid, reduce heat to low, and simmer for 15 minutes until the water is fully absorbed and the rice is tender. Remove from heat and gently fold through the fresh chopped dill and parsley.
Assemble the Rice Layer
Preheat your oven to 350°F (175°C). Transfer the fragrant mushroom rice mixture into a greased 9x13-inch baking dish, spreading it in an even, smooth layer.
Mash Potatoes & Spread Crust
Mash the warm drained potatoes with 1 tbsp butter, salt, black pepper, and freshly grated nutmeg until silky. Spread the mashed potatoes evenly over the mushroom rice layer. Use the tines of a fork to score decorative criss-cross ridges across the top (sprinkle with optional cheese).
Brush Glaze & Bake Golden
Whisk the melted butter with sweet paprika in a small cup. Generously brush the paprika butter wash over the scored potato top. Bake uncovered at 350°F (175°C) for 15–18 minutes until the ridges turn crisp, bubbly, and golden-red.
Slice & Serve
Let rest for 5 minutes, then slice into neat squares with a spatula. Serve warm as a main dish or comforting side.
❄️ Storing & Reheating Leftovers
Refrigeration: Allow the dish to cool to room temperature, then store in an airtight glass container in the refrigerator for up to 3 to 4 days.
Reheating: Reheat in a skillet over medium-low heat with a small splash of water or olive oil, or in a 350°F (175°C) oven until thoroughly warmed. This preserves the delicate moisture without drying out the texture.
