Hearty Vegetable Bake with Creamy Cucumber Sauce

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.

A Full List of Ingredients

Vegetable Base
• 2 medium zucchini, sliced ½ cm thick
• Salt, for drawing moisture from zucchini
• 50 g unsalted butter, plus 1 Tbsp sunflower oil
• 3 white leek stalks, white and light green parts, sliced
• 4 garlic cloves, minced
• 2 kohlrabi bulbs, peeled and cut into 1 cm cubes
• 1 medium sweet potato (about 200 g), peeled and cubed
• Salt and black pepper, to taste
• ½ tsp paprika
• ½ tsp dried Italian herb mix (oregano, basil, thyme)
• 100 g fresh spinach leaves

Batter
• 3 large eggs
• Salt and black pepper, to taste
• 1 tsp paprika
• 100 ml whole milk
• 150 g all‑purpose flour
• 7 g baking powder

Topping
• 100 g grated cheese (Gruyère, cheddar, or a blend)

Creamy Cucumber Sauce
• 1 Tbsp sour cream
• 1 Tbsp mayonnaise
• 1 small cucumber (about 100 g), peeled, seeded, and finely diced
• 1 garlic clove, minced
• Salt and pepper, to taste
• Optional: 1 Tbsp chopped fresh dill or parsley

Step‑by‑Step Cooking Directions

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. Fold cooled vegetable mixture into the batter, ensuring even distribution. Scrape mixture into prepared dish, smoothing the top with a spatula.

8. 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.

9. Meanwhile, whisk together sour cream, mayonnaise, diced cucumber, garlic, salt, and pepper in a small bowl. Chill briefly to let flavors meld.

10. 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.
