Keto Olive-Anchovy-Caper Antipasti Plate
Olives, anchovies and capers are all brine-cured and therefore naturally rich in sodium. Anchovies also deliver calcium from the tiny edible bones along with roughly 1.7 g of omega-3 per 100 g. This Mediterranean trio works without any cooking, takes minimal effort and covers sodium, calcium and healthy fats in a single serving, ready in under 10 minutes.
Key points at a glance
- Prep time approx. 10 minutes, no cooking, just plating.
- Approx. 3 g net carbs and 26 g fat per serving.
- Ingredients: mixed olives, anchovies in oil, capers, lemon, olive oil, parsley.
- Great for anyone who enjoys Mediterranean food on keto and wants a targeted boost of sodium and calcium.

Why are olives, anchovies and capers electrolyte sources on keto?
Thanks to brine curing, olives contain about 1.5 to 1.8 g of salt per 100 g and at the same time deliver oleic acid (a monounsaturated fat) and vitamin E. Anchovies in oil bring about 3.1 g of salt per 100 g, making them one of the saltiest ingredients around. Just as importantly, they also contain around 200 mg of calcium per 100 g from the fine bones that are processed along with the flesh. Capers contribute about 2.8 g of salt per 100 g plus quercetin, a flavonoid with antioxidant effects. Together, a typical portion delivers around 1.8 to 2.4 g of sodium, a meaningful contribution to the keto sodium balance.

Anchovies: an underrated source of calcium
On keto, calcium is often associated only with dairy. But anchovies, packed in oil with their soft little bones intact, deliver around 200 mg of calcium per 100 g, comparable to yogurt. Alongside sodium, potassium and magnesium, calcium is a key electrolyte for muscle function, especially for heart muscle contraction.
Which olives give you the best electrolyte effect?
Not all olives are equal. Green olives (Manzanilla, Castelvetrano) are firmer and carry more salt from the brine. Black olives (Kalamata, Taggiasca) are softer, more aromatic and richer in polyphenols. For maximum electrolyte impact, go with a mix. Olives stored in brine usually have a higher sodium content than those packed in oil.
How do I serve and vary the keto antipasti plate?
From my own experience, this plate is perfect as an aperitivo, as a starter, or as part of a keto charcuterie board with cheese and cured meats. In practice it also makes a quick post-workout calorie hit when time is short.
Meal prep: antipasti plate on standby
All components keep separately in the fridge for 5 to 7 days. For meal prep, layer the olives, anchovies and capers in a jar with good olive oil and lemon zest, also a lovely gift to bring along. Ready to serve straight from the jar.
Variation: marinated with rosemary and garlic
Warm the olives briefly in a pan with olive oil, garlic and fresh rosemary over low heat, do not fry them. This deepens the flavors and gives the olives a glossy, oily texture. Add the anchovies and capers only after the mixture has cooled.
Which tips make the keto antipasti plate better?
- Buy anchovies from a good tin or jar packed in olive oil. The salt-cured (dry-packed) ones have a more intense flavor but need rinsing first.
- Use an olive mix instead of a single type, different varieties and ripeness levels add depth of flavor.
- Non-pareille capers (the smallest size) have a more concentrated flavor than large capers.
- Lemon zest rather than juice, the essential oils in the peel are more aromatic and add no acidity.
- Save the high-quality olive oil for finishing, it is worth it in a dish with so few ingredients.

FAQ
How much sodium does one serving of antipasti contain?
Approx. 900 to 1,000 mg of sodium per serving from the olives, anchovies and capers combined. That covers around 30 to 40 percent of the daily sodium intake recommended on keto. The exact figure varies depending on the olive variety and how the anchovies were packed.
Can I leave out the anchovies if I do not like fish?
Yes. Skip the anchovies and add 30 g of cubed feta cheese instead. Feta delivers a similar amount of sodium plus calcium from dairy. You lose the omega-3 source, but the electrolyte effect stays strong.
Are olives really low in carbs?
Yes. Green and black olives contain around 3 to 6 g of carbs per 100 g, but 2 to 3 g of that is fiber, so net carbs land at roughly 1 to 3 g per 100 g. Since olives are usually eaten in small portions (30 to 60 g), the carbs are negligible.
Can I swap capers for olive paste?
Olive paste (tapenade) often already contains capers and is keto friendly at around 2 to 3 g net carbs per 100 g. It supplies a similar amount of sodium but less quercetin than fresh capers. A sensible substitute when capers are not on hand.
