This Golden Zucchini & Vegetable Breakfast Bake is a celebration of seasonal produce and simple pantry staples, layered into a one-dish wonder that feels both comforting and elegant. Thinly sliced zucchini is first tossed with salt to draw out excess moisture, then gently sautรฉed alongside aromatic onions, sweet carrots, and crisp bell peppers until tender and fragrant. Once drained and combined, these garden vegetables form a hearty base thatโs enriched by a silky, savory batter of eggs, milk, olive oil, flour, and a touch of baking powder for lift. Fresh garlic and dill, stirred in just before baking, infuse the mixture with bright, herbal notes that contrast beautifully with the mild zucchini. A generous blanket of melting cheese crowns the entire skillet, producing a golden, bubbling crust during its 35โ40-minute bake at 180 ยฐC (350 ยฐF). As it emerges from the oven, the casserole is garnished with a tangy yogurt-and-mayo drizzle, fresh lemon juice, and savory green onions, creating layers of creamy, citrusy, and crunchy textures. Whether enjoyed as a weekend brunch, a make-ahead breakfast for busy mornings, or a light vegetarian dinner, this bake delivers balanced nutrition, bold flavor, and fuss-free preparationโall in one glorious pan.

Step-by-Step Cooking Directions
-
Prepare and Salt the Zucchini
-
Place sliced zucchini in a large bowl. Sprinkle with 1 tsp salt and toss to coat evenly.
-
Let rest 10 minutes. The salt draws out excess moisture, preventing a watery bake.
-
-
Sautรฉ Aromatics & Vegetables
-
Heat 2 Tbsp sunflower oil in a large, oven-safe skillet over medium heat.
-
Add chopped onions; sautรฉ 3โ4 minutes until translucent.
-
Stir in grated carrot; cook 2 minutes until it begins to soften.
-
Add diced bell peppers; season lightly with salt and pepper. Cover and cook 5โ7 minutes, stirring occasionally, until peppers are tender-crisp.
-
Drain any liquid released by the salted zucchini and pat zucchini slices dry on paper towels. Add zucchini to the skillet; stir well to combine. Cover and cook 15 minutes over medium heat, stirring every 5 minutes until all vegetables are tender.
-
-
Whisk the Egg Batter
-
In a mixing bowl, crack in 3 eggs and whisk until just combined.
-
Pour in 240 ml milk and 30 ml olive oil; season with salt and pepper. Whisk until smooth.
-
Sift in 5 Tbsp flour and 10 g baking powder; whisk until no lumps remain.
-
-
Combine Garlic and Dill
-
Five minutes before the end of the vegetable cooking time, stir in minced garlic and chopped dill to release their aromatics without burning.
-
-
Assemble the Casserole
-
Preheat oven to 180 ยฐC (350 ยฐF).
-
Ensure the vegetable mixture is spread evenly in the skillet. Pour the prepared egg-milk batter over the top, tilting the pan if needed to distribute the batter completely.
-
Sprinkle 150 g shredded cheese evenly over the surface.
-
-
Bake Until Golden
-
Transfer the hot skillet to the preheated oven.
-
Bake uncovered for 35โ40 minutes, until the casserole is set in the center, the edges are golden, and the cheese is melted and bubbling. A toothpick inserted into the center should come out clean.
-
-
Prepare the Lemon-Yogurt Drizzle
-
While the bake rests, whisk together 2 tsp mayonnaise, 3 tsp plain yogurt, and juice of ยฝ lemon. Adjust seasoning with salt and pepper to taste.
-
-
Garnish and Serve
-
Remove casserole from oven and let rest 5 minutes.
-
Drizzle lemon-yogurt sauce over the top, then scatter sliced green onions evenly.
-
Serve warm or at room temperature, slicing directly in the skillet or transferring to a cutting board.
-
Serving Suggestions
-
Pair with a crisp arugula salad tossed in lemon-olive oil vinaigrette for peppery contrast.
-
Offer slices with a side of herbed toast or crusty baguette to scoop up extra sauce.
-
Serve alongside fresh fruit, such as melon slices or berries, for a balanced brunch spread.
-
Accompany with a light white wine (e.g., Sauvignon Blanc) or sparkling cider to complement the creamy tang.
Common Mistakes to Avoid
-
Not Salting Zucchini Properly: Skipping the salting step leads to excess water release, resulting in a soggy bake.
-
Overcrowding the Pan: Too many vegetables in the skillet can cause steaming rather than sautรฉingโuse a large pan or cook in batches.
-
Uneven Baking: If batter pools on one side, rotate the skillet halfway through baking for uniform rise and browning.
-
Burning the Garlic: Add garlic toward the end of sautรฉing to prevent bitterness from overcooking.
Variations to Try
-
Spinach & Feta: Swap zucchini for baby spinach and mix in crumbled feta instead of the shredded cheese.
-
Mexican-Style: Stir in 1 tsp chili powder and ยฝ tsp cumin to the batter; top with pepper jack cheese and serve with salsa and avocado.
-
Mushroom Medley: Add 150 g sliced mushrooms with the onions for an earthy twist.
-
Gluten-Free: Use a 1:1 gluten-free flour blend in place of all-purpose flour.
