- 1 bell pepper (capsicum), diced
- 200g oyster mushrooms, sliced into strips
- 500g chicken fillet (breast or thigh), diced
- 2 tbsp soy sauce
- 1 tbsp sugar
- Salt and black pepper to taste
- 2 tbsp cornstarch (cornflour)
- 3 cloves garlic, minced
- 50g fresh spinach
- 2 tbsp olive oil (for the pan)
- 3 eggs
- 100ml heavy cream (whipping cream)
- Paprika powder
- 100g mozzarella, grated
- For the Sour Cream-Mustard Dip:
- 100g sour cream
- 100g mayonnaise
- 2 tsp mustard
- Salt and pepper to taste
- Fresh parsley (for garnish)
Step-by-Step Cooking Directions
- Prepare the Asparagus: Wash the asparagus thoroughly. If using fresh, snap off the woody ends and cut the stalks into roughly 3 cm (1.2 inch) pieces. Bring a pot of water to a boil. Add the asparagus and blanch for 5 minutes. Drain well and set aside.
- Sauté Vegetables and Mushrooms: Heat 2 tablespoons of olive oil in a large skillet or frying pan over medium-high heat. Add the diced onion, diced bell pepper, and sliced oyster mushrooms. Sauté for about 5 minutes, stirring occasionally, until the vegetables and mushrooms are softened. Season with salt, pepper, and cornstarch, stirring to coat evenly.
- Brown the Chicken: Add the diced chicken fillet to the same pan. Cook over medium-high heat, stirring as needed, until the chicken is golden brown on all sides. Season with soy sauce, sugar, salt, and pepper. Add the minced garlic and cook for another minute until fragrant.
- Add Spinach: Stir in the fresh spinach and cook until it wilts down, about 1-2 minutes. Mix everything in the pan together thoroughly.
- Prepare the Egg Mixture: In a separate bowl, whisk together the 3 eggs, heavy cream, a pinch of paprika powder, and salt.
- Assemble and Bake: Transfer the chicken and vegetable mixture from the skillet into a baking dish. Distribute it evenly. Pour the prepared egg mixture over the chicken and vegetables. Sprinkle the grated mozzarella evenly over the top. Bake in a preheated oven at 190°C (374°F) for 25 minutes, or until the cheese is melted, bubbly, and golden brown, and the casserole is heated through.
- Make the Sour Cream-Mustard Dip: While the casserole bakes, prepare the dip. In a small bowl, whisk together the sour cream, mayonnaise, mustard, salt, and pepper until smooth and well combined.
- Garnish and Serve: Once the casserole is ready, remove it from the oven. Garnish generously with freshly chopped parsley. Serve warm with the sour cream-mustard dip on the side. Enjoy your meal!

Serving Suggestions
This casserole is a complete meal on its own, but you can serve it with:
- Warm Crusty Bread: Perfect for soaking up any creamy sauce.
- Simple Green Salad: A light, fresh salad with a vinaigrette dressing to add crunch and contrast.
- Rice or Quinoa: For an even heartier meal, a small side of cooked rice or quinoa.
Common Mistakes to Avoid
- Overcooking Asparagus: Blanching for too long can make asparagus mushy. Stick to 5 minutes for tender-crisp results, especially if using fresh.
- Overcrowding the Pan: When sautéing vegetables, especially mushrooms, avoid overcrowding. This steams them instead of browning, leading to less flavor. Cook in batches if necessary.
- Under-seasoning: Chicken and vegetables can be bland without proper seasoning. Taste and adjust salt, pepper, and soy sauce as you cook.
- Baking Too Long: Over-baking can dry out the chicken and make the casserole rubbery. Bake until the cheese is golden and bubbly, and the egg mixture is set.
- Forgetting Cornstarch: The cornstarch in the vegetable step helps thicken any liquids and ensures a cohesive filling, so don’t skip it.
Pairing Recommendations
- Wine: A crisp Sauvignon Blanc, a light-bodied Pinot Grigio, or a dry Rosé would complement the fresh asparagus and chicken beautifully.
- Beer: A light lager, a pilsner, or a crisp pale ale would be refreshing alongside this dish.
- Non-Alcoholic: Freshly brewed iced tea, sparkling water with a slice of lemon, or a light vegetable juice.
Cooking Tips
- Fresh Asparagus: If using fresh asparagus, ensure you trim the woody ends by holding the stalk and bending it; it will naturally break where the tender part begins.
- Mushroom Browning: For the best flavor, allow the mushrooms to brown well in the pan before adding other ingredients. This process develops their deep, earthy notes.
- Flavor Boost: A dash of white wine or vegetable broth can be added to the pan with the vegetables for extra depth.
- Cheese Variety: Feel free to experiment with other good melting cheeses like Gruyère, provolone, or a Parmesan blend for the topping.
- Adjust Seasoning: Always taste the chicken and vegetable mixture before adding the egg mixture and adjust seasonings as needed.
- Herb Freshness: Using fresh parsley for garnish adds a vibrant pop of color and fresh aroma.
