Can I use other mushrooms instead of button mushrooms?

Yes, oyster mushrooms or wild mushrooms (pre-boiled) work well. The flavor becomes more intense and earthy.

Why did my casserole turn out watery?

The mushrooms or tomatoes may have released too much liquid. You can sauté the mushrooms briefly before adding them, and use firm, meaty tomatoes.

How long should I bake the casserole?

About 40 minutes at 180–200°C (350–400°F). If the top browns too quickly, cover with foil for the last 10 minutes.

Can I make it without eggs?

The egg binds the topping. If you don't have one, replace it with 2 tablespoons of flour or cornstarch mixed with a little water.

SIMPLE PROCESS

Step by step recipe

For a juicy, non-dry casserole, layer the ingredients properly and avoid overcooking the chicken. The cheese-sour cream topping with egg adds a creamy texture and a golden crust. Tomatoes and mushrooms add moisture and depth of flavor. Follow the steps for a perfect casserole that the whole family will love.

Step 1

Prep the Chicken

Rinse and pat dry the chicken breast with paper towels. Cut into small pieces or strips. Place in a lightly oiled baking dish and season with salt.

Step 2

Add the Tomatoes

Wash and dry the tomatoes, slice into ½-inch thick rounds. Arrange them in a single layer over the chicken.

Step 3

Add the Mushrooms

Wash, dry, and slice the mushrooms. Distribute them evenly over the tomatoes and sprinkle lightly with salt.

Step 4

Make the Topping

In a bowl, mix sour cream, grated cheese, eggs, and salt. Stir until smooth and well combined.

Step 5

Top and Bake

Spread the cheese-sour cream mixture evenly over the casserole. Place in a preheated oven at 180–200°C (350–400°F) and bake for 40 minutes until the top is golden and bubbly.

Step 6

Serve

Let the casserole rest for 10 minutes before slicing. Serve hot. Enjoy!

CHEF'S TIP

Use Fresh Chicken and Mushrooms

For the best juiciness, use chilled boneless, skinless chicken breast. Choose fresh mushrooms with firm caps — they release more flavor and hold their shape during baking.

Cut Ingredients Evenly

Slice the chicken into bite-sized pieces or strips, the mushrooms into slices, and the tomatoes into rounds. This ensures even cooking and a beautiful presentation.

Use Full-Fat Sour Cream

Sour cream with at least 20% fat won't curdle during baking and gives a richer topping. If using low-fat sour cream, add 1 tablespoon of flour to thicken it.

Let It Rest

After baking, let the casserole rest for 10 minutes — it sets and becomes easier to slice into clean portions.

SUBSTITUTIONS

Add your taste

With Chicken Thighs Replace chicken breast with boneless thighs — they are juicier and more flavorful, though higher in calories. Increase baking time by 10 minutes.
With Mayonnaise Instead of Sour Cream Use mayonnaise instead of sour cream for a richer, thicker topping. Calories will increase slightly, but the flavor will be more intense.
With Broccoli Instead of Tomatoes Replace tomatoes with broccoli florets — the dish becomes more colorful and even more diet-friendly.
Add Potatoes Layer thinly sliced potatoes at the bottom of the dish before adding the chicken for a more filling, complete meal.

HOW TO STORE

How to Store Chicken Casserole

Cool the casserole to room temperature, then store in an airtight container in the fridge for up to 3 days. Reheat in the oven at 160°C (320°F) for 10–15 minutes or in the microwave. Freeze in portions for up to 2 months — thaw in the fridge and reheat in the oven.
