Baked gnocchi gratin: comfort dinner in a tray

Ingredients

• 1 kg floury potatoes
• 300 g all-purpose flour (plus extra for dusting)
• 1 egg
• Salt
• 500 g tomato passata
• 1 garlic clove
• 2 tablespoons extra-virgin olive oil
• Fresh basil
• 250 g mozzarella
• 60 g grated Parmesan
• Black pepper

Method

1. Boil the potatoes with the skin on until tender, then peel and mash while hot.
2. Add egg, salt, and flour gradually until you get a soft, non-sticky dough.
3. Roll into ropes and cut gnocchi. Dust lightly with flour and set aside.
4. Make the sauce: warm oil and garlic, add passata, simmer 10-12 minutes with basil.
5. Cook gnocchi in salted water; when they float, lift them out with a slotted spoon.
6. Toss gnocchi with sauce and part of the Parmesan.
7. Transfer to a baking dish, add mozzarella cubes and the remaining Parmesan.
8. Bake at 200 C for 15-18 minutes until golden and bubbly.

Soft dough, no stress

The key to tender gnocchi is working the potatoes while they are hot. Cold potatoes absorb more flour and turn heavy.

I use starchy potatoes. If they are watery, I bake them in the oven instead of boiling to keep them dry.

Simple sauce and stretchy finish

The sauce is intentionally simple so the gnocchi stay the star. Garlic, passata, basil. If I want more depth, I add a spoon of tomato paste.

I always drain the mozzarella. I cube it and chill it for 20 minutes so it does not water down the dish in the oven.

Cooking and the oven

Gnocchi only need a short bath in water. As soon as they float, I lift them out. The oven finishes the cook and keeps them soft.

I use a not-too-large baking dish so the layer stays compact and gratins better.

How I prep ahead

If I need to plan ahead, I shape the gnocchi and keep them on a floured tray. I cook them right before baking.

The sauce can be done the day before. The next day I just reheat and assemble.

Variations I actually use

Sometimes I add ham or grilled vegetables between the layers. Zucchini and eggplant work great.

For a deeper flavor, I swap mozzarella for smoked scamorza.

Common mistakes

Too much flour makes gnocchi dense. A soft dough and gentle hands are better.

Wet mozzarella makes the dish watery. Dry it before baking.

Storage

It keeps in the fridge for 2 days. I reheat in the oven with a spoon of water or sauce to keep it moist.

Before I start, I line up everything: sauce ready, tray ready, mozzarella dry. It keeps me calm and the steps flow.

I use a fine grater for Parmesan so it melts evenly and makes a smooth crust.

A small trick: a thin drizzle of oil on top before baking helps the color without drying the gnocchi.

When friends come over, I assemble early and bake at the last minute. It hits the table hot and fragrant.

This is one of those dishes that feels like home. The tomato smell from the oven is a signal: dinner is close.

If I want a lighter version, I reduce the mozzarella and use a bit more sauce. It still tastes rich.

The dough should be handled quickly. The more you work it, the tighter it gets.

If I have extra gnocchi, I freeze them on a tray and then bag them. That turns into a future easy dinner.

For me the final gratin is the best part. It is quick, but it changes the texture completely.

I like serving it with a fresh salad on the side to balance the richness.

When slicing portions, I use a wide spoon to keep the gnocchi intact and the serving neat.

If the sauce feels too thick, a ladle of gnocchi water loosens it and helps it coat better.

I use fine salt in the dough so it spreads evenly. Coarse salt stays in little pockets.

Sometimes I add a basil leaf on each portion. Small detail, big effect.

If I am cooking for many people, I split the dough in two so it stays soft and quick to handle.

This dish saves me when I want comfort without making things complicated. Simple, dependable, and always satisfying.

When I cook this, I remind myself that calm beats speed: a few good steps, done with care, always work.

The detail that makes it work

When I make Baked gnocchi gratin, I focus on the last adjustment of flavor; it is what ties everything together. With 60 minutes with Medium effort, it is a recipe I can repeat easily. To keep the budget (€€), I balance with seasonal vegetables and one main protein.
