Recipe Overview
- Prep Time: 15 minutes
- Cook Time: 35 minutes
- Servings: 4–5 portions
Ingredients
- 1 medium butternut squash, peeled, cubed, and boiled until tender
- 2 cooked chicken breasts, cut into bite-sized pieces or shredded
- 150g (5 oz) feta cheese, cut into small cubes
- 1 cup cherry tomatoes, halved
- 1 small onion, finely chopped
- 3 large eggs, beaten
- 1 cup shredded mozzarella cheese
- 2 tbsp olive oil
- ½ tsp black pepper
- ½ tsp dried chili flakes (optional)
- Salt, to taste
Step-by-Step Instructions
1. Prepare and Roast the Squash Base
Preheat your oven to 180°C (350°F). Place the boiled butternut squash in a baking dish and mash it evenly to form a smooth base. Drizzle with olive oil and season with black pepper and a pinch of salt. Bake in the oven for 10 minutes to lightly roast the squash base and evaporate any excess moisture.
2. Layer the Toppings
Remove the dish from the oven. Spread the cooked chicken pieces evenly over the squash layer. Top with the halved cherry tomatoes, finely chopped onion, and feta cheese cubes.
3. Add the Egg Binding
Pour the beaten eggs evenly over the chicken and vegetable layers to bind everything together as it bakes. Sprinkle with dried chili flakes if you enjoy a gentle touch of heat.
4. Add Cheese and Bake
Cover the entire top with a generous layer of shredded mozzarella cheese. Return the dish to the preheated oven and bake for 20 to 25 minutes, or until the egg mixture is fully set and the mozzarella is completely melted, bubbly, and lightly golden brown.
5. Rest and Serve
Remove from the oven and let the casserole rest for 5 minutes before slicing. Garnish with fresh chopped parsley or coriander and serve warm!
Helpful Cooking Tips
- Drain Squash Well: Ensure the boiled butternut squash is thoroughly drained before mashing to avoid a watery base.
- Pre-Cooked Chicken: Using leftover roasted, boiled, or rotisserie chicken breast speeds up preparation significantly.
- Let It Rest: Resting the dish for 5 minutes after baking allows the egg mixture and melted cheese to set, making it much easier to slice neatly.
Tasty Customization Ideas
- Veggie Boost: Add fresh spinach leaves, diced zucchini, sliced bell peppers, or mushrooms to the vegetable layer.
- Herb & Spice Twist: Season the squash base with garlic powder, smoked paprika, dried oregano, or fresh thyme for extra depth.
- Cheese Variations: Combine feta with sharp cheddar or Parmesan cheese for a richer topping.
