How to Make Stuffed Castelvetrano Olives with Garlic and Herb Boursin Recipe

Step 1: Create the Infused Olive Oil

Start by warming the olive oil with minced garlic and dried herbs in a small saucepan over medium heat. You’ll want to gently heat the mixture until it sizzles and the garlic becomes fragrant, which takes about one minute of careful simmering while swirling the pan. This process releases the essential oils from the garlic and herbs, creating a deeply aromatic base for marinating the olives. Once achieved, remove from the heat, season with sea salt, and allow the oil to cool to room temperature.

Step 2: Prepare the Olives

The Castelvetrano olives must be pitted if they are not already. Using an olive pitter or a cherry pitter works perfectly for this. If the olives contain any unwanted stuffing, use a skewer or chopstick to carefully remove it without damaging the olive itself. This careful preparation ensures each olive is a perfect vessel for the creamy Boursin.

Step 3: Fill the Olives with Boursin Cheese

Take the garlic and herb Boursin cheese and mash it lightly with a fork to soften it. Transfer the cheese to a piping bag or a large zip-top bag, snip off a corner sized to fit each olive’s opening, and carefully pipe the cheese into the cavities. Filling from bottom to top allows each olive to be generously stuffed with the creamy mixture, guaranteeing a rich flavor in every bite. Place the stuffed olives into a quart-sized jar to begin the marinating process.

Step 4: Combine and Marinate

After stuffing every olive, pour the cooled garlic and herb olive oil over them in the jar. Ensure the oil fully covers the olives to infuse them with flavor. Seal the jar and refrigerate for at least 30 minutes, though allowing up to a week lets the flavors meld beautifully. Remember to turn the jar a few times before serving to keep the herbs and oil evenly distributed. If the olive oil solidifies in the refrigerator, simply let it come to room temperature before enjoying your delicious creation.

Make Ahead and Storage

Storing Leftovers

Keep any leftover stuffed Castelvetrano olives tightly covered in their marinade inside the refrigerator. Stored properly, they will stay fresh and flavorful for up to one week, making them a perfect make-ahead favorite for effortless entertaining.

Freezing

Because of their delicate texture and creamy filling, freezing stuffed Castelvetrano olives with garlic and herb boursin recipe is not recommended. Freezing can alter the consistency of both the olives and cheese, resulting in a less enjoyable eating experience.

Reheating

These olives are best enjoyed cold or at room temperature. If the olive oil has solidified, simply let the jar sit out for 15–20 minutes before serving to soften it. There’s no need to heat them, as that can change the textures and flavors you’re aiming to savor.

FAQs

Can I use other types of olives for this recipe?

While Castelvetrano olives are preferred for their buttery, mild flavor and ideal size, you can experiment with other large green olives. Just be mindful the taste and texture may differ, which can subtly change the final result.

What if I can’t find Garlic and Herb Boursin cheese?

If Boursin is unavailable, try substituting with another soft, garlicky herb cheese like a cream cheese blended with fresh garlic and herbs. The flavor won’t be exactly the same but will still complement the olives nicely.

How spicy is this recipe? Can I adjust the heat level?

The red chili flakes provide gentle heat that balances the creaminess. You can adjust the quantity to your taste — omit entirely for no spice or increase it slightly if you enjoy a bit more kick.

Is this recipe suitable for parties and large gatherings?

Absolutely! With 45 stuffed olives per batch, this recipe is perfect for sharing. It’s easy to scale and great for preparing in advance, making it an ideal crowd-pleaser at any event.

How long does the marinating process improve the flavor?

Marinating for at least 30 minutes allows the garlic and herbs to infuse nicely, but letting the olives sit for 24 hours or up to a week really deepens the flavor profile. Just be sure to keep them refrigerated during this time.
