Every holiday table needs one thing you can put out without thinking, and for us it is a bowl of warm olives. Brined olives go into olive oil with strips of orange peel, sliced garlic, rosemary, fennel seed, and a pinch of red pepper, then warm just long enough to wake up the aromatics. The whole thing takes 15 minutes, uses ingredients you likely already have, and tastes like something you fussed over. Make a jar early in the week and you have a New Year’s Eve appetizer that is ready before the first guest rings the bell.
Why Warm Olives With Orange Peel Work
Olives are already cured and seasoned, so you are not really cooking them here; you are dressing them. Gentle heat does two useful things. It softens the olives just enough to feel plush instead of firm, and it pulls flavor out of the garlic, rosemary, fennel, and pepper flakes. Orange peel brings its own oil, and warm olive oil draws that citrus perfume out of the colored part of the skin. A splash of vinegar and orange juice goes in off the heat, so the acid stays bright and does not sputter in the pan. The result is a bowl that hits every note a good appetizer should: salty, rich, a little tart, and fragrant enough that people ask what is in it.
What Goes Into Orange-Peel Marinated Olives
The ingredient list is short, and the only thing worth shopping carefully for is the oil, since it becomes the sauce. Use a good extra-virgin olive oil you would be happy to dip bread into.
- 2 cups mixed brined olives (Castelvetrano, Kalamata, or green), drained, about 10 ounces
- 1/3 cup good extra-virgin olive oil
- 3 strips orange peel, about 2 inches each, white pith scraped off
- 2 tablespoons fresh orange juice
- 1 tablespoon red wine vinegar (or white wine vinegar)
- 3 cloves garlic, thinly sliced
- 1 tablespoon chopped fresh rosemary
- 1/2 teaspoon red pepper flakes (or 1/4 teaspoon for mild)
- 1/2 teaspoon fennel seeds, lightly crushed
- 1/2 teaspoon whole black peppercorns
No Castelvetrano? Any firm green olive works; Kalamata brings a saltier, more assertive bite. Red wine vinegar can become white wine or sherry vinegar. If you want less heat, use 1/4 teaspoon of red pepper flakes, or swap in Aleppo pepper for a softer warmth. Not a fennel fan? Leave the seeds out and add a bay leaf instead. Dried rosemary is fine in a pinch, but use about 1 teaspoon, since it is stronger than fresh. If your olives taste very salty, rinse them for a minute longer and pat them dry well.
Tips for Marinated Olives That Taste Made-Ahead
Pat the olives dry before they hit the pan. Water in hot oil spits, and dry olives coat more evenly.
Watch the garlic, not the clock. It should turn pale gold at the edges, never brown, because burnt garlic turns the whole batch bitter.
Add the orange juice and vinegar with the pan off the heat. The oil is hot enough to spit when acid hits it, and pulling the pan aside keeps the citrus tasting fresh.
Peel only the orange part. The white pith underneath is bitter, so scrape it away with a spoon before slicing the peel into strips.
Give the olives at least an hour in the fridge before serving. The flavor deepens as they sit, and that is the whole point of a make-ahead appetizer.
Storing and Serving Orange-Peel Olives
Cool the olives completely, then move them to a covered jar with all the oil and aromatics. They keep in the refrigerator for up to a week, and the oil will solidify once it gets cold, which is normal. Let the jar stand at room temperature for about 15 minutes before serving so the oil loosens and turns glossy again. Serve them warm or at room temperature with toothpicks, next to bread, cheese, and something bubbly. A small bowl of these also makes a good host gift, as long as you remember to bring back the jar.
Marinated Olives With Orange Peel: 15-Minute Make-Ahead Appetizer
Ingredients
Method
- Drain the olives in a colander, rinse under cold water, and pat dry with paper towels.
- Warm the olive oil in a medium saucepan over medium-low heat. Add the garlic, orange peel, rosemary, red pepper flakes, fennel seeds, and peppercorns. Cook, stirring, until fragrant and the garlic is pale gold at the edges, 2 to 3 minutes; do not let it brown.
- Add the olives and stir to coat. Cook until heated through, 3 to 4 minutes.
- Take the pan off the heat and stir in the orange juice and vinegar, then return it to low heat for 1 minute. Adding the juice off the heat keeps it from spitting in the hot oil.
- Serve warm with toothpicks, or cool completely and refrigerate in a covered jar with the oil and aromatics for at least 1 hour and up to 1 week for a deeper flavor.
- Let refrigerated olives stand at room temperature for 15 minutes before serving, since the oil solidifies when cold.
None of this requires a party. A jar of these olives in the fridge means you have a real appetizer on hand for a Tuesday snack or an unexpected knock at the door. Buy a few extra oranges while they are in season, and the rest is pantry work.
