Baked Zucchini, Potato and Chicken Casserole with Cheese

This easy baked zucchini, potato and chicken casserole is hearty, juicy, and full of flavour. Grated vegetables create a soft and tender base, finely chopped chicken adds protein, breadcrumbs help the mixture hold together, and a layer of tomato and melted cheese finishes everything beautifully. It is an excellent family-style recipe because all the ingredients are simple, inexpensive, and easy to prepare. The most important part is controlling the moisture from the zucchini and potatoes. If you remove the excess liquid properly, the casserole will bake evenly instead of becoming watery. This savoury bake is the kind of dish that looks like something from a cosy bistro menu, yet is built from everyday ingredients you probably already have in your kitchen.

🍗 Discover A Golden Chicken And Vegetable Bake That Brings Restaurant‑Style Comfort Straight To Your Home Table

Grated courgette, potato, onion and carrot form a soft, flavourful vegetable base that holds moisture and sweetness, while diced chicken breast adds gentle protein and substance without making the dish heavy. Eggs and a little flour bind everything together into a tender, sliceable mixture that bakes into a comforting, almost pie‑like texture, with spices, paprika and fresh garlic bringing warmth and depth to every bite. Before baking, you lay the mixture over a thin layer of breadcrumbs, which helps create a subtle crust and prevents sticking, making it easy to cut neat portions once the dish is cooked. Sliced tomatoes on top add colour and freshness, turning into a soft, slightly roasted layer that contrasts beautifully with the creamy vegetables underneath. In the final minutes, you shower the hot bake with grated hard cheese and return it to the oven, allowing the cheese to melt and form a golden, savoury topping that makes the whole dish feel indulgent and inviting.

🧀 Savour The Moment When The Cheese Melts Into A Golden, Bubbling Topping That Makes The Whole Dish Feel Indulgent

👨‍🍳 How to Make Baked Zucchini, Potato and Chicken Casserole

Step 1: Preheat the Oven

Preheat your oven to 180°C conventional heat or about 170°C fan-assisted.

Lightly grease a baking dish with a small amount of olive oil, or line it with baking parchment.

A medium baking dish around 20 × 25 cm works well for this quantity.

Chef’s tip: Do not use a dish that is too small. If the mixture is very thick, the centre will take much longer to cook.

Step 2: Grate the Zucchini

Wash the zucchini and trim off both ends.

Grate it using the coarse side of a box grater.

There is no need to peel young zucchini.

Place the grated zucchini in a clean kitchen towel.

Squeeze firmly to remove as much liquid as possible.

This step is essential. Zucchini contains a lot of water, and if that moisture goes into the casserole, the centre can become soggy.

Chef’s secret: You may be surprised by how much liquid comes out. Keep squeezing until only a small amount remains.

Step 3: Grate the Potatoes

Peel the potatoes and grate them coarsely.

Transfer them to another towel or piece of cheesecloth and squeeze out excess moisture.

Potatoes contain less free water than zucchini but still release enough liquid to affect the texture.

Beginner tip: Work relatively quickly after grating potatoes because they begin to darken when exposed to air.

Step 4: Grate the Carrot and Onion

Peel the carrot and grate it coarsely.

Peel the onion and grate it as well.

The grated onion will release plenty of juice. You can press it lightly, but you do not need to make it completely dry.

Chef’s tip: Grating rather than chopping the onion helps it disappear into the casserole and distribute its flavour evenly.

Step 5: Prepare the Chicken

Pat the chicken breast dry with paper towel.

Cut it into very small cubes, ideally around 5–8 mm.

The smaller the pieces, the more evenly they will cook inside the casserole.

Important: Avoid large chunks. This dish cooks as one thick layer, so small pieces of chicken are much safer and more tender.

Chef’s secret: Slightly chilled chicken is easier to chop very finely than warm chicken.

Step 6: Combine the Vegetables and Chicken

Place the squeezed zucchini, potatoes, carrot, onion, and chopped chicken in a large bowl.

Mix gently so the ingredients are evenly distributed.

At this point, the mixture should look moist but not watery.

If liquid begins collecting at the bottom of the bowl, drain it before adding the remaining ingredients.

Step 7: Add the Eggs and Seasonings

Add:

• 2 eggs
• 5 g salt
• 1 g black pepper
• 2 g smoked paprika
• 1 finely grated or minced garlic clove

Mix thoroughly.

The eggs act as a binder and help hold the vegetables and chicken together during baking.

Chef’s tip: Smoked paprika adds depth without making the dish particularly spicy. If you prefer stronger heat, add a small pinch of chilli flakes.

Step 8: Add the Flour

Add 30 g wheat flour.

Mix until the flour is fully distributed.

You should not see any dry pockets.

The flour absorbs some of the remaining vegetable moisture and helps the finished casserole hold its shape.

Chef’s secret: Do not add much more flour unless the mixture is extremely wet. Too much flour can make the casserole dense and doughy.

Step 9: Add the Olive Oil

Pour in 45 ml olive oil.

Mix again until everything is evenly coated.

The oil prevents the casserole from becoming dry and helps the vegetables cook more gently.

Tip: If your chicken is very lean, the olive oil is especially helpful for keeping the finished dish juicy.

Step 10: Prepare the Breadcrumb Layer

Sprinkle 30 g breadcrumbs evenly over the bottom of the prepared baking dish.

This creates a thin layer that absorbs some of the moisture released during baking.

It also helps prevent the bottom from becoming soggy.

Chef’s tip: Fine breadcrumbs work best here. Panko can also be used, but it creates a slightly rougher texture.

Step 11: Spread the Mixture into the Dish

Transfer the vegetable and chicken mixture into the baking dish.

Spread it evenly with a spatula.

Press it very lightly so there are no large gaps, but do not compact it firmly.

Aim for an even thickness throughout the dish.

Chef’s secret: An even layer is important because thin areas can dry out before thicker areas are cooked.

Step 12: Add the Tomato

Slice the tomato thinly.

Arrange the slices evenly across the top of the casserole.

Do not overlap them too heavily.

Chef’s tip: If the tomato is extremely juicy, blot the slices gently with paper towel before adding them.

This prevents unnecessary moisture from collecting on top.

Step 13: First Bake

Place the dish on the middle rack of the oven.

Bake at 180°C for 35 minutes.

During this stage, the vegetables soften, the eggs set, and the chicken cooks through.

Do not add the cheese yet.

How to check: After 35 minutes, the surface should look set and the edges should begin to turn lightly golden.

For food safety, the chicken should be fully cooked through in the centre.

Step 14: Add the Cheese

Remove the dish carefully from the oven.

Sprinkle 100–120 g grated cheese evenly over the surface.

Make sure the cheese reaches close to the edges.

Chef’s tip: A mix of mozzarella and a stronger cheese such as Gouda or Parmesan gives both good melting and better flavour.

Step 15: Bake Again

Return the casserole to the oven.

Bake at 180°C for another 10 minutes.

The cheese should melt completely and begin to turn lightly golden.

For a more browned finish, you can use the grill function for the final 1–2 minutes.

Watch closely because cheese can burn quickly.

Step 16: Rest Before Cutting

Remove the casserole from the oven.

Let it rest for 10–15 minutes before cutting.

This may seem unnecessary, but it makes a big difference.

The eggs, flour, and vegetable juices settle during resting, making the casserole easier to slice.

Chef’s secret: Cutting immediately can make the centre seem softer and wetter than it really is.

Step 17: Slice and Serve

Cut into squares or rectangular portions.

Serve warm.

It pairs particularly well with:

• green salad
• cucumber salad
• garlic yoghurt sauce
• sour cream
• fresh herbs
• roasted vegetables

👨‍🍳 Chef’s Best Tips

Squeeze the zucchini thoroughly. This is the most important step for avoiding a watery casserole.

Drain the potatoes too. Even a little excess moisture can soften the base.

Chop the chicken finely. Small pieces cook evenly and stay tender.

Do not overload the dish. A very thick layer takes longer to bake and may remain wet in the centre.

Use the breadcrumbs on the bottom. They help absorb juices and improve the texture.

Blot a very juicy tomato. This keeps the topping from becoming watery.

Add cheese only near the end. Baking it for the entire cooking time can make it dry or overly dark.

Let the casserole rest. Ten minutes of resting gives cleaner slices.

Use smoked paprika for flavour. It works especially well with chicken, potatoes, and cheese.

Yes.
It is especially useful when the potatoes are very juicy after grating.

Can I grate everything in a food processor?

Yes.
A grating attachment saves time and works very well.
Just remember to squeeze the zucchini and potatoes afterward.

Can I use chicken thigh instead of chicken breast?

Yes.

Absolutely.
Turkey breast is an excellent substitute.

Can I add more vegetables?

Yes.
Good additions include:

• bell pepper
