Crispy oven-baked smashed potatoes are a simple alternative to fried potatoes: they stay soft in the centre, develop golden edges and need only a little oil. For this version, the potatoes are boiled whole, pressed directly on the baking tray, then baked at a high temperature. Finally, a cold yogurt and lemon sauce adds freshness and balances the intense flavour of the crust.

This recipe works both as a side dish for meat and as a light vegetarian meal. Serve it with a simple salad, fried eggs, or a more substantial dish such as creamy chicken with garlic and Parmesan made in a pan.

Ingredients for 4 servings

For the potatoes

1 kg small or medium potatoes with thin skins
3 tablespoons olive oil or sunflower oil
1 level teaspoon salt, plus salt for the cooking water
1/2 teaspoon freshly ground black pepper
1 teaspoon sweet or smoked paprika
1/2 teaspoon granulated garlic, optional
1 teaspoon finely chopped rosemary leaves or dried thyme

For the yogurt and lemon sauce

200 g Greek yogurt or full-fat plain yogurt
1 tablespoon lemon juice
1 small garlic clove, finely grated
1 tablespoon chopped dill or parsley
1 teaspoon olive oil
Salt and pepper, to taste
1–2 tablespoons cold water, only if the sauce is too thick

Total time: approximately 55 minutes
Preparation time: 15 minutes
Boiling and baking time: 40 minutes

Choosing potatoes

Use small or medium potatoes that are as similar in size as possible. This way, they cook evenly and can be pressed easily without turning into mash. New potatoes are a good choice when you can find them, but the recipe also works with regular firm-fleshed potatoes.

There is no need to peel them. Well-washed skins contribute to the crisp texture and reduce prep time. Wash the potatoes under running water and rub them gently to remove any soil. For vegetables that will be cut or cooked, washing them under running water before preparation is a simple hygiene measure; do not use detergent or food soap.

Method, step by step

1. Boil the potatoes until tender

Place the whole potatoes in a large pot and cover them with cold water.
Add one teaspoon of salt and put the pot over the heat.
Once the water starts to boil, cook the potatoes for 15–20 minutes. The time depends on their size.
Test them with the tip of a knife: it should slide in easily towards the centre, but the potato should not split apart on its own.

Drain the potatoes well. Leave them for 5 minutes in the colander or in the empty pot, uncovered. As the steam evaporates, it dries their surface, which later helps the crust form. If you press them immediately after boiling, while they are still very wet, they will bake soft rather than crisp.

2. Prepare the tray and smash the potatoes

Preheat the oven to 220°C with conventional top-and-bottom heat. If you have a fan setting, set it to 200°C.
Line a large baking tray with baking paper and brush the paper with a little oil.
Space the potatoes apart. Do not crowd them: the room between them allows the hot air to brown them.
Press each potato with the bottom of a flat-based glass, a wide spatula or a potato masher. Press only until the potato is around 1–1.5 cm thick and the edges crack slightly.

If the glass sticks, grease its base with a drop of oil. Do not press too hard: very thin potatoes can dry out before their edges brown nicely.

3. Season and bake

Mix the remaining oil with the salt, pepper, paprika, granulated garlic and rosemary or thyme.
Brush the smashed potatoes with this mixture, making sure to cover the uneven surface and edges.
Bake for 25–30 minutes, until the edges are golden and crisp.
For a deeper crust, you can turn on the oven grill for the final 2–3 minutes. Keep a close eye on the tray, as the paprika and herbs can burn quickly.

4. Make the cold sauce

Mix the yogurt with the lemon juice, garlic, herbs, oil, salt and pepper. If the yogurt is very thick, thin the sauce with one or two tablespoons of cold water. Taste before serving: some lemons are more acidic, and the amount of juice can be adjusted without spoiling the recipe.

Serve the potatoes hot, with the sauce in a separate bowl or spread on the plate. Top with dill, parsley, finely sliced spring onion or a few chilli flakes, if you like a mildly spicy flavour.

Tips for truly crispy potatoes

Boil them only until tender. If they become too soft in the water, they will fall apart when pressed.
Let them release their steam. Five minutes of resting after draining matters more than it seems: less surface moisture means better browning.
Use enough oil, but do not drown them in it. Three tablespoons per kilogram of potatoes are enough for a flavourful crust.
Do not overcrowd the tray. If they are pressed against one another, the potatoes will steam. It is better to use two trays than one that is too full.
Bake at a high temperature. At 180°C, the potatoes heat through and dry out, but brown more slowly. A temperature of 220°C is better suited to this dish.

What to serve with oven-baked smashed potatoes

For a meat-free dinner, pair them with roasted vegetables and a leafy salad. If you want a more filling plate, they go very well with seasoned roasted chickpeas or a warm salad with crispy chickpeas and yogurt dressing. The two dishes use compatible ingredients, and the sauce can be made in a larger quantity and used for both.

The potatoes can also replace the classic side served with a burger. If you are preparing a weekend menu, serve them alongside a smash burger with caramelised onions, with the yogurt sauce served separately for a refreshing contrast.

Simple recipe variations

Smashed potatoes with Parmesan

Sprinkle 40–50 g finely grated Parmesan over the potatoes during the final 8 minutes of baking. Do not add it at the start, as it may brown too much before the potatoes are hot inside.

Lenten smashed potatoes

Replace the yogurt sauce with a tahini sauce: mix two tablespoons of tahini with lemon juice, garlic, salt and cold water, adding the water gradually. For more ideas without ingredients of animal origin, see this selection of delicious Lenten recipes.

Mediterranean-style potatoes

Replace the rosemary with dried oregano and add a few very finely chopped olives to the sauce. Serve with cherry tomatoes and cucumber for a simple summer meal.

Common mistakes and how to fix them

Problem	Likely cause	Solution
The potatoes are not crispy	They were too wet or the tray was too crowded.	Drain them well, leave them to release steam for 5 minutes and keep space between them.
The potatoes fall apart when pressed	They were boiled for too long.	Next time, check them earlier; the knife should go in easily, not cut straight through them.
The seasonings become bitter	They spent too long at a very high temperature or under the grill.	Use less paprika and turn on the grill only at the end, for a maximum of 2–3 minutes.
The sauce is too sour	The lemon juice was added all at once.	Add a tablespoon of yogurt and adjust with a little salt.

Storage and reheating

The potatoes are best straight after baking, when the contrast between the soft centre and crispy crust is most evident. If there are leftovers, let them cool and store them covered in the refrigerator. For food safety, cooked leftovers should be refrigerated promptly, and refrigerated dishes are generally eaten within 3–4 days.

Reheat the potatoes on a baking tray at 200°C for 8–10 minutes. Avoid the microwave if you want to preserve a crispy crust. Store the yogurt sauce separately and stir it before serving.

In short: boil the potatoes until tender, dry them for a few minutes, press them moderately and bake them at a high temperature. These are simple steps, but they are precisely what turn an ordinary side dish into a dish with crisp edges and distinctive flavour.

Frequently asked questions

Which potatoes are best for oven-baked smashed potatoes?

Choose small or medium potatoes of similar size with firm flesh. New potatoes are practical because they have thin skins, but regular potatoes also work well if they are not excessively floury.

Do I have to boil the potatoes before baking?

Yes, boiling is the step that ensures a soft interior. Smashing makes the surface uneven, and the oven browns the exposed edges.

Why are my smashed potatoes not crispy?

The most common causes are excess moisture after boiling, too little oil, too low a temperature or an overcrowded tray. Let the potatoes release their steam and bake them at 220°C.
