Imagine a casserole that highlights the natural sweetness of zucchini, leeks, kohlrabi, and sweet potato, each gently sautéed in a buttery sunflower oil blend with garlic and Italian herbs. Those veggies are then combined with wilted spinach and a simple batter made from eggs, milk, flour, and seasoning. Poured into a parchment‑lined pan, the mixture bakes into a golden, soufflé‑like dish with a light, tender crumb. Five minutes before the end of baking, a shower of grated cheese melts into a bubbly, slightly crisp top. Paired with a creamy cucumber and garlic sauce—made from sour cream, mayonnaise, diced cucumber, and a hint of garlic—this bake delivers layers of flavor and texture: the earthiness of root veggies, the brightness of spinach, the richness of cheese, and the cool tang of the sauce. It’s elegant enough for dinner guests, yet easy enough for a satisfying weeknight meal.

• 1 Tbsp sour cream

Step‑by‑Step Cooking Directions
-
Preheat oven to 180 °C (350 °F). Lightly grease a 20×20 cm baking dish and line with parchment paper, leaving an overhang for easy removal.
-
Place sliced zucchini in a colander, sprinkle lightly with salt, and toss. Let sit 10–15 minutes to draw out moisture, then gently squeeze and pat dry.
-
In a large skillet over medium heat, melt butter with oil. Add leek and sauté 2–3 minutes until translucent. Add garlic and cook 1 minute until fragrant.
-
Increase heat to medium‑high. Add kohlrabi and sweet potato cubes. Season with salt, pepper, paprika, and Italian herb mix. Sauté 2–3 minutes until edges begin to color.
-
Add zucchini and cook 2–3 minutes, stirring—each vegetable should be just tender, not mushy. Stir in spinach and cook until wilted, about 1 minute. Transfer mixture to a bowl and let cool slightly.
-
In a mixing bowl, whisk eggs with a pinch of salt, pepper, and paprika until pale. Stir in milk until smooth. In another bowl, combine flour and baking powder; sift into egg mixture. Fold gently to create a thick, lump‑free batter.
-
Fold cooled vegetable mixture into the batter, ensuring even distribution. Scrape mixture into prepared dish, smoothing the top with a spatula.
-
Bake uncovered for 35 minutes, until edges are set and top begins to color. Remove from oven, sprinkle cheese evenly across the surface, and return to oven for 5 minutes until melted and golden.
-
Meanwhile, whisk together sour cream, mayonnaise, diced cucumber, garlic, salt, and pepper in a small bowl. Chill briefly to let flavors meld.
-
Remove the bake from oven and let rest 5 minutes. Lift from dish using parchment overhang and transfer to a cutting board. Slice into squares or wedges. Serve warm, drizzled or sided with creamy cucumber sauce.
