Marinated Mozzarella Balls
Marinated mozzarella balls are creamy little bites of bocconcini soaking in a jar of herby olive oil with a little heat. Set the jar on a holiday cheese board or tie a ribbon on it for a hostess gift. They’re a make ahead appetizer since the flavor gets better overnight. It’s 10 minutes of prep plus an overnight rest, and it makes 8 servings.

My cheese board theory is simple. A proper one should be at least a square mile. (My counter disagrees.)
So I fill the gaps on my cheese board with stuff that pulls its weight, and a jar of these is just the gap filler I grab. It takes up one little corner, it looks fancy, and people keep going back to fish out “just one more.”
This recipe used to be goat cheese balls. Then my photographer made them with mozzarella for the photo shoot, and I decided mozzarella deserved the spotlight. Goat cheese fans, don’t panic. The swap is in the Variations.
A jar of these is also a great answer when you get invited somewhere and don’t want to show up empty handed. Make a few jars, tie on a ribbon, and the host gets something way better than another candle.
I’ve got a few more things for the board linked below, too.

Ingredient Notes
Bocconcini – These are the bigger fresh mozzarella balls packed in water, not the tiny pearls. Drain off the water before they go in the jar.

How to Make Marinated Mozzarella Balls

- Pour 1/4 cup of olive oil into the bottom of the jar and add a few sprigs of thyme and rosemary.

- Drain the bocconcini.
- Add a layer of mozzarella balls to the jar.

- Add more thyme, rosemary, red pepper flakes and peppercorns, then pour in a little olive oil to fill the gaps.

- Keep layering herbs, spices and mozzarella until all the cheese is in the jar.
- Pour in the rest of the olive oil until it’s within 1/2 inch of the top, then add the last of the herbs and spices.

- Seal the jar tightly and put it in the fridge for at least an hour but overnight is best. Turn it upside down overnight so everything gets coated, then turn it right side up the next day.
- Take the jar out of the fridge before serving so the olive oil can turn liquid again.
For the full recipe and detailed instructions, please refer to the recipe card at the bottom of the post.

Storage
Keep the jar sealed in the fridge and eat the mozzarella within 3 to 4 days of marinating. The olive oil firms up in the fridge, so let the jar sit out until the oil turns liquid again before serving.
Variations
Goat Cheese – Swap the bocconcini for a 10 ounce log of plain goat cheese. Scoop it into 1 inch balls and roll them smooth in your hands. A little olive oil on your hands keeps the goat cheese from sticking as it warms up. Then layer them in the jar the same way. The goat cheese version keeps 3 to 4 days in the fridge too.

Frequently Asked Questions
I marinate mine in olive oil with fresh thyme, fresh rosemary, red pepper flakes and whole peppercorns.
They keep in the fridge for 3 to 4 days after you marinate them. Keep the jar sealed.
Set the jar out on a cheese board with a little fork or toothpicks so people can fish them out. They’re also great on breakfast toast with avocado.
Trader Joe’s has sold marinated mozzarella, but what’s on the shelf changes by store and season, so check yours. Or make a jar at home in 10 minutes and pick your own herbs.

Recipe Tips & Tricks
- Flip the jar: Turning it upside down overnight gets herbs and oil all over every ball. Don’t skip it.
- Give it time to warm up: Straight out of the fridge, the oil is solid. Pull the jar out ahead of time so it’s pourable when guests show up.
- Use a jar with a good seal: I use Weck jars in the 2 cup size, and an olive oil dispenser with a pour spout makes filling the jar a lot less messy.
- Date the gift: If a jar is going home with someone, write the date on the tag so they know to eat it within 3 to 4 days.
