What is the cheapest cooking oil in Switzerland?
In 2026 the cheapest everyday oil in Switzerland is a supermarket own-brand rapeseed or blended vegetable oil. Coop sells Prix Garantie vegetable oil for around CHF 2.50 per litre and Lidl its Vita d'or rapeseed oil for around CHF 2.49. Rapeseed oil rates as the healthiest all-rounder in the Kassensturz lab test, sunflower oil is usually similarly cheap, and olive oil costs several times more at up to CHF 8 per litre.
As of June 2026. All prices are per-litre guide values from the chains' own-brand lines and change every week. Rappn is neutral and has no commercial deal with any retailer, so we only state what the sources support. Where a figure could not be hard-confirmed this session, we flag it openly.
Which oil is cheapest per litre: rapeseed, sunflower or blended vegetable oil?
On pure price per litre, an own-brand discount oil almost always wins. Coop's Prix Garantie vegetable oil (a blend, often sunflower with some soy or rapeseed) carries the lowest shelf price, followed by plain rapeseed oil. Pure sunflower oil usually sits slightly above. Olive oil plays in a completely different league, more on that below. The table sums up the guide values confirmed via the shop and test pages this session.
| Oil (1-litre own-brand) | Chain | Guide price per litre | Source |
|---|---|---|---|
| Vegetable oil (blend) | Coop Prix Garantie | approx. CHF 2.50 | coop.ch |
| Rapeseed oil | Lidl Vita d'or | approx. CHF 2.49 | Lidl / saldo.ch |
| Rapeseed oil | Coop Prix Garantie | approx. CHF 3.50 | coop.ch |
| Swiss rapeseed oil (Suisse Garantie) | Aldi Bellasan / Denner | varies weekly, compare live in Rappn | Aldi / Denner |
| Sunflower oil | Coop Prix Garantie | approx. CHF 4.95 | coop.ch |
| Rapeseed oil M-Budget | Migros | approx. CHF 3.50 | migipedia.migros.ch, as of June 2026 |
The key point: no single store is cheapest every week. The discount lines (Prix Garantie at Coop, M-Budget at Migros, Vita d'or at Lidl, Bellasan at Aldi) all sit close together, and the weekly promotion decides the winner. That is exactly what a neutral price comparison makes visible.
Which oil is best for frying and deep-frying?
Here it is not price that matters but heat stability. A lab test by Kassensturz (SRF) and Saldo examined 20 of the best-selling rapeseed and sunflower oils. The result: all 20 lived up to their "suitable for frying" claim, but quality varied. Three rapeseed oils scored best, the Bellasan rapeseed oil from Aldi, the Sabo oil (sold at Manor) and the Volg own brand. The so-called HO and HOLL oils (High Oleic for sunflower, HOLL for rapeseed) showed the best heat and storage stability, but a weaker frying aroma. For high temperatures and deep-frying, HOLL rapeseed oil and HO sunflower oil are the safe choice. Source: Kassensturz/SRF and Saldo.
Between rapeseed and sunflower there was barely any difference in heating or aroma. However, several sunflower oils fell short on freshness and oxidation stability, while rapeseed oil stayed fresher on the shelf and scored on its better omega-3 to omega-6 ratio. That makes rapeseed the health winner, with extra-virgin olive oil the flavour winner.
Before you grab the next bottle: a quick look in the Rappn app shows which chain near you has the cheapest rapeseed or sunflower oil this week, across all 7 chains.
Sunflower vs rapeseed vs olive oil: what goes in the basket for cooking?
For everyday use (searing, sweating, neutral sauces) rapeseed and sunflower oil are the cheapest and most practical all-rounders. Rapeseed has the rounder nutritional profile, sunflower the more neutral taste. Olive oil belongs more on the salad or the finished dish, and it has become markedly more expensive in 2026: according to 20 Minuten, a litre of Coop Prix Garantie olive oil vergine now costs around CHF 8, up roughly 16 percent, because crop failures in Italy, Spain and Greece have pushed purchasing prices up. Rapeseed and sunflower prices fell over the same period. So if you want to save, cook with rapeseed or sunflower and use olive oil sparingly.
| Use | Best value oil | Why |
|---|---|---|
| Searing, wok, medium heat | Rapeseed oil (own brand) | cheap, good omega ratio, neutral |
| Deep-frying, high heat | HOLL rapeseed / HO sunflower | best heat and storage stability (Kassensturz) |
| Salad, cold finish | Extra-virgin olive oil | flavour, but expensive in 2026 (up to CHF 8/l) |

Frequently Asked Questions
What is the cheapest cooking oil in Switzerland?
The cheapest are the discount own brands: Coop Prix Garantie vegetable oil is around CHF 2.50 per litre and Lidl's Vita d'or rapeseed oil around CHF 2.49 (as of June 2026, sources coop.ch and saldo.ch). Pure sunflower oil is usually slightly more. The Rappn app shows which chain in your region is cheapest this week.
Rapeseed or sunflower oil for frying, which is better?
Both fry well. In the Kassensturz/Saldo lab test there was barely a difference when heated, but rapeseed stayed fresher and has the better omega-3 to omega-6 ratio. For high heat and deep-frying, HOLL rapeseed or HO sunflower oil is the most stable.
Why is olive oil so much more expensive than rapeseed oil?
Drought-driven crop failures in Italy, Spain and Greece have sharply raised purchasing prices. According to 20 Minuten, a litre of Coop Prix Garantie olive oil vergine now costs around CHF 8, about 16 percent more. Rapeseed and sunflower oil have become cheaper over the same period.
What does HOLL mean on rapeseed oil?
HOLL stands for High Oleic, Low Linolenic. These rapeseed varieties were bred for a high share of stable oleic acid and a low share of fragile linolenic acid. That makes HOLL oil especially heat- and storage-stable, ideal for frying and deep-frying, with a slightly milder frying aroma than classic rapeseed oil.
Is it worth buying the cheapest oil?
For everyday cooking, yes: in the test all 20 rapeseed and sunflower oils met their claim, and some own brands (Aldi's Bellasan, Volg) were even among the winners. More expensive does not automatically mean better here. Comparing still pays off, because the weekly price per litre swings between chains.
