Crustless Spinach, Onion & Olive Cake
This savory crustless cake is like a cross between a frittata and a Mediterranean quiche — filled with sautéed onions, wilted spinach, and briny olives, all baked into a fluffy, cheesy egg base. It’s light, satisfying, and absolutely packed with Mediterranean flavor.
⏱️ Time:
Prep Time: 15 minutes
Cook Time: 30–35 minutes
Total Time: 45–50 minutes
Ingredients:
1 tbsp olive oil
1 medium red or yellow onion, thinly sliced
2–3 cups fresh spinach (or 1 cup frozen, thawed and squeezed dry)
½ cup chopped pitted Kalamata or black olives
4 large eggs
½ cup whole milk or Greek yogurt
½ cup crumbled feta cheese (or shredded mozzarella)
2 tbsp chopped parsley or dill
Salt & pepper to taste
Optional: ¼ tsp nutmeg or ½ tsp oregano for extra depth
Instructions:
1. Preheat the Oven:
Preheat to 375°F (190°C). Grease a 9-inch pie dish or baking pan.
2. Sauté Veggies:
Heat olive oil in a skillet. Add sliced onion and sauté over medium heat for 6–8 minutes until soft and golden.
Add spinach and cook just until wilted (if using fresh). Remove from heat and let cool slightly.
3. Mix the Batter:
In a large bowl, whisk together eggs, milk or yogurt, salt, pepper, and herbs.
Stir in cooked onions and spinach, chopped olives, and feta or cheese of choice.
4. Bake:
Pour the mixture into the greased dish.
Bake for 30–35 minutes, or until set and lightly golden on top.
Let rest for 5–10 minutes before slicing.
Serving Suggestions:
Serve warm or at room temp with a side salad, tzatziki, or roasted veggies.
Excellent for brunch, lunchboxes, or a light dinner with toasted pita.
Tips & Variations:
Make it dairy-free: Use dairy-free milk and skip the cheese, or use vegan feta.
Boost the protein: Add chopped cooked chicken or smoked salmon.
Swap greens: Use kale, chard, or even grated zucchini (just squeeze moisture out first).
Want it spicy? Add a pinch of red chili flakes or chopped jalapenos.
