Cheese options: Mozzarella gives you a stretchy, creamy texture. Parmesan adds a salty, savory flavor. You can also use cheddar, Gouda, or feta, or combine two cheeses.
Cream substitute: Replace the heavy cream and milk with ¾ cup (180 ml) whole milk for a lighter version. The filling may be slightly less rich.
2. Step-by-step cooking instructions

Step 1 — Prepare the oven and dish
Preheat the oven to 180°C (350°F). Lightly grease an 8–9-inch baking dish with butter or oil. A glass, ceramic, or oven-safe metal dish will work.

Step 2 — Cook the mushrooms
Heat the olive oil or butter in a skillet over medium-high heat. Add the sliced mushrooms and cook for 5–7 minutes, until browned and their released moisture has evaporated. Add the onion, if using, and cook for another 2–3 minutes. Stir in the garlic for 30 seconds.

Step 3 — Add the spinach
Add the spinach and cook for 1–2 minutes, until wilted. Frozen spinach can also be used, but thaw it completely and squeeze out as much water as possible. Let the vegetables cool slightly.

Step 6 — Bake until golden
Bake for approximately 30–40 minutes, depending on the depth of the dish and your oven. It should be puffed, lightly golden, and set in the center. The middle should not look liquid or runny.

Step 7 — Rest and serve
Rest for 8–10 minutes before slicing. This helps the eggs firm up and makes the dish easier to serve. Garnish with fresh parsley or a little extra black pepper.

5. Tips for the best results
Avoid a watery filling: Brown the mushrooms thoroughly and remove excess liquid from the spinach before assembling.
Get a golden top: Sprinkle a little extra cheese over the surface. If necessary, use the oven grill/broiler briefly at the end, watching carefully to prevent burning.
Keep the center tender: Avoid overbaking. Check for a set center and use a food thermometer if possible; egg dishes should reach at least 71°C (160°F) internally.
Make it richer: Use heavy cream and a mixture of mozzarella and Parmesan.
Add more vegetables: Bell peppers, broccoli, zucchini, or sun-dried tomatoes can work. Cook moisture-rich vegetables first.
Add more protein: Diced cooked chicken or turkey can be added if you do not need a vegetarian dish.
Make it spicy: Add chili flakes, cayenne, or a small amount of chopped green chili.
6. Storage and reheating
Refrigerator: Cool promptly and refrigerate in a covered container within 2 hours. Use within 3–4 days.
Freezer: Freeze individual portions in airtight containers for up to 2–3 months for best quality.
Reheating: Warm in the oven at 160°C (320°F) until heated through, or microwave individual portions in short intervals.
Food safety: Reheat leftovers to 74°C (165°F). Avoid leaving the egg dish at room temperature for extended periods.
7. Frequently asked questions (Q&A)
Q1. Is this a frittata or a quiche?
It is closest to a baked frittata or crustless quiche. A traditional quiche usually has a pastry crust and a richer custard filling, while a frittata is egg-based and often baked without a crust.
Q2. Can I make it without cream?
Yes. Use milk instead. The result will be less rich, so avoid adding too much liquid and cook until the center is set.
Q3. Can I use frozen spinach?
Yes. Thaw it, squeeze out excess water, and measure approximately 100–150 g after draining.
Q4. Why is my baked egg dish watery?
Mushrooms and spinach hold a lot of water. Cook the mushrooms until browned, drain the spinach well, and avoid adding too much milk.
Q5. Can I prepare it in advance?
Yes. Cook the vegetables in advance and refrigerate them. For the best texture, combine them with the egg mixture shortly before baking, or assemble and refrigerate briefly before baking.
Q6. How do I know when it is cooked?
The edges should be set, the center should not be liquid, and the top should be lightly golden. The center should reach at least 71°C (160°F).
Q7. Can I make it without mushrooms?
Yes. Replace them with extra spinach, sautéed peppers, broccoli, or zucchini.
Q8. Is this recipe suitable for weight loss?
It can fit into a balanced eating plan. For a lighter version, use less cheese, replace heavy cream with milk, and serve with salad or vegetables. Overall energy intake and portion size matter most.
Q9. Is it keto-friendly?
Generally, yes. Eggs, cheese, spinach, and mushrooms are relatively low in carbohydrates. Check the nutrition labels and your serving size to determine the actual carbohydrate content.
Q10. What can I serve with it?
Serve it with a green salad, roasted vegetables, whole-grain toast, fresh tomatoes, or a light soup.
Q11. Can I cook it on the stovetop?
Yes. Cook it in a covered, oven-safe skillet over low heat until mostly set, then finish under a grill/broiler if the pan is suitable. The oven method generally produces a more evenly cooked result.
Q12. Can I make it dairy-free?
Yes. Use an unsweetened, suitable plant-based milk and dairy-free cheese. The texture and browning may differ from the original.
