Orange marinated olives are a bright, briny appetizer where good-quality olives are soaked in extra-virgin olive oil with fresh orange zest and juice, garlic, herbs, and a touch of chili. The citrus cuts through the saltiness of the olives while the oil carries the aromatics into every bite. This Mediterranean-style dish comes together in minutes and only gets better as it sits, making it a perfect make-ahead starter for any gathering.
Ingredients
- 3 cups (450 g) mixed olives (such as Castelvetrano, Kalamata, and Cerignola), drained and patted dry
- 1/2 cup (120 ml) extra-virgin olive oil
- 1 orange, zested and juiced (about 1 tbsp zest and 3 tbsp juice)
- 3 cloves garlic, thinly sliced
- 1 tsp (5 g) fennel seeds, lightly crushed
- 1/2 tsp (1 g) red pepper flakes (optional, for heat)
- 1 bay leaf
- 1 tsp (6 g) kosher salt, or to taste
- Fresh herbs: 2 sprigs rosemary or 3 sprigs thyme
Instructions
- In a medium saucepan over medium heat, warm the olive oil, orange zest, orange juice, garlic, fennel seeds, red pepper flakes (if using), bay leaf, salt, and fresh herbs. Heat until the oil is shimmering and the garlic is fragrant, about 3–5 minutes. Do not let the garlic brown.
- Remove the pan from heat and let the oil cool for 5 minutes.
- Place the olives in a large bowl or a glass jar. Pour the warm oil mixture over the olives, making sure they are fully submerged. If needed, add a little more oil to cover.
- Let the olives cool to room temperature, then cover and refrigerate for at least 1 hour to allow the flavors to meld. For best results, let them marinate overnight.
- Before serving, bring the olives to room temperature (about 30 minutes) so the oil is liquid and the flavors are vibrant. Serve in a shallow bowl with a slotted spoon, drizzling a little of the oil on top.
Tips
- Choose the right olives: Use a mix of mild and briny olives. Castelvetrano (green) are buttery, Kalamata are tangy, and Cerignola are meaty. Avoid pre-stuffed olives (like pimento) as they can be mushy.
- Don’t skip the drying step: Pat the olives completely dry before marinating. Excess moisture dilutes the oil and can make the marinade cloudy.
- Adjust the heat: If you prefer a milder version, omit the red pepper flakes or use just a pinch. For more spice, add a small dried chili like arbol.
- Use a good quality oil: Since the oil is a major component, use an extra-virgin olive oil you enjoy eating. A fruity or peppery oil will shine through.
Serving Suggestions
Serve these olives as part of an antipasto platter with salami, prosciutto, cheeses, and crusty bread. They also make a great garnish for cocktails like a martini or negroni, or as a topping for crostini with a smear of ricotta. The leftover oil is delicious drizzled over grilled vegetables, salads, or pasta.
Variations
- Lemon-Herb: Replace the orange with lemon zest and juice, and use oregano instead of rosemary.
- Spicy Moroccan: Add 1 tsp (2 g) smoked paprika and 1/2 tsp (1 g) ground cumin to the oil.
- Garlic-Lover’s: Double the garlic and add 1/4 cup (25 g) sliced shallots.
- Fresh Citrus: Add strips of orange peel (without the white pith) for a more intense citrus aroma.
Storage and Reheating
Store the olives in an airtight container in the refrigerator for up to 2 weeks. The oil will solidify when cold; that’s normal—just let them come to room temperature before serving. To reheat, place the olives with some oil in a skillet over low heat for 2–3 minutes, just until warm. Do not microwave, as it can make the olives rubbery. The olives are best served at room temperature, so avoid reheating unless you prefer them warm.
Frequently Asked Questions
Can I use canned or jarred olives? Yes, but choose whole olives (not sliced) and drain them well. Avoid olives packed in vinegar or with lots of brine, as they can be too sour.
How long do marinated olives last? In the refrigerator, they will keep for up to 2 weeks. Always use a clean spoon to remove olives, and make sure they are fully submerged in oil to prevent spoilage.
Can I freeze marinated olives? Yes, you can freeze them in a freezer-safe container for up to 3 months. Thaw in the refrigerator overnight and bring to room temperature before serving. The texture may soften slightly.
Why is my olive oil cloudy? Cloudiness is usually caused by water from the olives or juice. Patting the olives dry and not adding too much orange juice can help. It’s harmless but less pretty.
Can I use orange juice from a carton? Fresh orange juice is best for flavor. Carton juice may contain preservatives or added sugar, which can alter the taste.
Should I remove the pits? It’s traditional to leave pits in for flavor and presentation. Warn guests about them. If you prefer, you can pit the olives before marinating, but they will be softer.
