These addictive and simple citrus-marinated olives are a delicious appetizer or snack made with just a few simple ingredients in less than 15 minutes. Plump, juicy Castelvetrano olives are steeped in a flavorful olive oil made with lots of tangy citrus and red chiles to become the best Mediterranean citrus olives for charcuterie boards.
Halve and thinly slice one half of the lemon and of the orange. Set aside the other halves for juicing.
Using a vegetable peeler, peel the grapefruit and set the grapefruit aside for another use. If the peels are too long, cut shorter.
Warm the extra virgin olive oil in a small pot over medium heat.
Add the crushed red pepper, lemon slices, orange slices, and the grapefruit peel.
Cook for 1-2 minutes and then add the olives.
Reduce the heat to the lowest possible setting on your stove.
Continue cooking for 10 minutes up to an hour. If your stove cannot go low, only cook for up to 30 minutes.
Let the olives cool to room temperature in the pot.
Squeeze the juice of the reserved lemon half and the orange half into the pot. Stir.
Serve warm with the peels.
Notes
These olives can be marinated in advance. Store in an airtight container in the refrigerator for up to a month. Gently re-warm the olives to room temperature either on the stove or on the counter. This recipe is best not frozen.
