Tossing your favourite olives with fresh basil pesto is one of the simplest ways to create a flavour-packed party snack in minutes. These pesto marinated olives are quick, vibrant, savoury and ideal for effortless entertaining, whether you are planning a drinks party, building an antipasti board or need a last-minute appetiser for guests.

It is always useful to have a few easy party snack recipes you can rely on, especially when people arrive unexpectedly or you want to put something impressive on the table without cooking. This recipe is exactly that kind of idea. Open a jar of olives, stir through a generous spoonful of basil pesto, loosen everything with a little olive oil and you have a colourful, Mediterranean-style appetiser ready to serve.
The beauty of pesto marinated olives is that the ingredients are simple, but the flavour tastes much more special than the effort involved. The salty richness of the olives works beautifully with the herby freshness of basil pesto, while the olive oil helps coat every olive so each bite is glossy and full of flavour. Serve them straight away, or make them ahead and let the flavours mingle in the fridge.
These olives are lovely with pita chips, crusty bread or soft no-knead focaccia. They also fit perfectly into a larger grazing spread with dips, marinated feta, marinated mini mozzarella balls and other easy nibbles. They are casual enough for a relaxed evening but delicious enough to include on a holiday appetiser table.
Ingredients
You only need three ingredients to make these easy pesto marinated olives. Because the recipe is so simple, choose ingredients you genuinely enjoy. Good olives and a good pesto will make the biggest difference to the final flavour.

- Olives. Use your favourite olives, or choose a mixed selection for colour and variety. Kalamata olives are a great option because they are rich, briny and full of flavour. Pitted olives are easiest for guests to eat, but unpitted olives can also be used if you prefer them.
- Pesto. A fresh basil pesto gives the olives a bright, herby flavour. Homemade basil pesto is a wonderful choice if you have it, but a good-quality shop-bought pesto will also work.
- Olive oil. A little olive oil loosens the pesto so it coats the olives evenly. It also gives the finished dish a glossy texture and helps the marinade spread through the bowl.
How to make them
Making pesto marinated olives could not be easier. Drain the olives well, place them in a mixing bowl, then add the pesto and olive oil. Gently stir until the olives are completely coated. You can serve them immediately, but if you have time, let them sit for a little while so the pesto can settle into the olives and create an even deeper flavour.
If you are using unpitted olives and would rather serve them without stones, remove the pits before mixing. Pitted olives are especially good for this recipe because the pesto can settle into the centres, making every bite more flavourful. Once mixed, transfer the olives to a serving dish and add small skewers or cocktail sticks on the side for easy snacking.


Got a question?
They will keep well for at least one week when stored in a glass jar or covered container in the fridge. Give them a gentle stir before serving so the pesto and oil coat the olives again.
Either will work, but pitted olives are easier to eat and better for casual entertaining. They also allow the pesto to move into the centre of the olives, which gives you more flavour in every bite.
Yes. Basil pesto is classic, but red pepper pesto, sundried tomato pesto, wild garlic pesto or spicy zhoug sauce would also be delicious with olives.

These pesto marinated olives are an easy no-cook appetiser made with mixed olives, basil pesto and olive oil. They are salty, herby, glossy and perfect for serving with bread, dips or an antipasti-style party spread.
Ingredients
- 325g/11oz drained mixed olives, such as pitted Kalamata and green olives
- 1/2 cup basil pesto
- 1 tablespoon olive oil
Instructions
- Prepare the olives. Drain the olives from their brine and place them in a mixing bowl. If you are using unpitted olives and want to remove the stones, do that before marinating.
- Add the pesto. Spoon the basil pesto into the bowl, then add the olive oil. Stir gently until the olives are evenly coated and the pesto is loosened into a glossy marinade.
- Serve. Transfer the olives to a serving dish and serve straight away, or cover and chill until needed. Stir again before serving if the pesto settles.
Notes
Storage: Store the olives in a glass jar or covered container in the fridge for at least one week.
Ingredient notes: A mixture of pitted olives gives the best variety and makes the olives easy to eat. You can also use unpitted olives if you prefer. Basil pesto is delicious, but red pepper pesto, sundried tomato pesto, wild garlic pesto or spicy zhoug sauce can also be used.
Serving suggestions: Serve as part of a party platter with marinated feta, pita chips, dips, focaccia and marinated mini mozzarella balls. They can also be tossed through pasta or added to salads for extra flavour.
