Description for Marinated Mozzarella & Olive Antipasto Jar

This Marinated Mozzarella & Olive Antipasto Jar combines creamy mozzarella, juicy cherry tomatoes, mixed olives, and thinly sliced red onion in a fragrant olive oil marinade. Garlic, rosemary, thyme, and Italian herbs give every bite a rich, savory flavor, while a splash of vinegar adds brightness.

The combination is simple but satisfying. Mozzarella brings a mild, creamy texture, olives add saltiness, and tomatoes provide a sweet contrast. As the ingredients chill together, the herbs and garlic flavor the marinade and coat everything beautifully.

Serve this colorful antipasto as an appetizer, spoon it onto toasted bread, or add drained portions to a Mediterranean platter. It is especially convenient for entertaining because you can prepare it the evening before serving. A transparent jar also makes the layers of cheese, vegetables, and herbs look attractive on the table.

🛒 Ingredients for Marinated Mozzarella & Olive Antipasto Jar

For the Antipasto

8 oz (225 g) fresh mozzarella pearls or mini bocconcini, drained
1 cup cherry or grape tomatoes, whole or halved
1½ cups mixed pitted olives, drained
½ small red onion, very thinly sliced
2 small fresh rosemary sprigs
2–3 fresh thyme sprigs
2 dried bay leaves

For the Olive Oil Marinade

1½–2 cups extra-virgin olive oil, as needed to cover
2 tablespoons red wine vinegar or white balsamic vinegar
3–4 garlic cloves, thinly sliced
1 teaspoon dried oregano
1 teaspoon dried basil or Italian seasoning
½ teaspoon crushed red pepper flakes, or less to taste
Up to ½ teaspoon kosher salt, depending on the olives
¼ teaspoon freshly cracked black pepper

Equipment for Marinated Mozzarella & Olive Antipasto Jar

Use one clean, completely dry, wide-mouth jar with approximately 1½-quart capacity, or divide the ingredients between two smaller jars. You will also need a mixing bowl, whisk, and clean serving spoon.

👩‍🍳 Instructions for Marinated Mozzarella & Olive Antipasto Jar

1. Prepare the mozzarella.

Drain the mozzarella thoroughly and gently pat it dry with paper towels.
If using larger bocconcini, cut them into bite-size pieces. Leave small mozzarella pearls whole.

Removing excess liquid helps the marinade cling to the cheese instead of becoming diluted. Handle fresh mozzarella gently so the pieces keep their shape.

2. Prepare the tomatoes and olives.

Wash the tomatoes and dry them well. Leave small tomatoes whole or halve larger ones.
Drain the olives and check that all pits have been removed.

Whole tomatoes stay firmer during overnight marinating. Halved tomatoes release more juice and absorb the dressing more quickly. A mixture of red and orange tomatoes gives the jar extra color.

3. Slice the onion and garlic.

Cut the red onion into very thin half-moons.
Peel the garlic and slice it thinly so its flavor spreads throughout the oil.

For a milder onion flavor, soak the slices in cold water for 5–10 minutes. Drain and dry thoroughly before adding them to the other ingredients.

4. Prepare the herbs.

Rinse the rosemary and thyme, then pat them completely dry.
Keep the sprigs whole so you can remove the woody stems easily before serving.

Small sprigs are enough. Too much rosemary can overpower the delicate mozzarella, especially when the mixture marinates overnight.

5. Mix the marinade.

In a bowl, whisk together 1½ cups olive oil, vinegar, sliced garlic, oregano, basil, red pepper flakes, and black pepper.
Add a little salt only if needed.

Taste an olive before seasoning the marinade. Some olives are already salty enough, so you may not need the full measured amount.

6. Combine the ingredients.

Place the mozzarella, tomatoes, olives, and onion in a large bowl.
Pour over the marinade and fold gently until everything is coated.

Use a spoon or flexible spatula rather than vigorous stirring. This protects the mozzarella and prevents halved tomatoes from breaking apart.

7. Fill the jar.

Spoon the mixture into the prepared jar, distributing the cheese, tomatoes, olives, and onion evenly.
Tuck the rosemary, thyme, and bay leaves between the ingredients.

Pour in the remaining marinade from the bowl. Add extra olive oil only as needed to cover the ingredients, leaving approximately ½ inch of space below the lid. Do not pack the jar tightly.

8. Refrigerate immediately.

Close the lid and place the jar in the refrigerator.
Chill for at least 2–4 hours, or overnight for a fuller flavor.

Gently turn or tilt the closed jar once during marinating to redistribute the dressing. Keep it refrigerated throughout the marinating period.

9. Serve.

Remove only the amount you plan to serve and let it stand briefly, approximately 15 minutes, to soften the chilled oil.
Remove the bay leaves and woody herb stems, then transfer the antipasto to a serving bowl with a slotted spoon.

Serve with crostini, crackers, warm pita, or crusty bread. A little marinade can be spooned over each serving for extra flavor.

💡 Helpful Cooking Tips for Marinated Mozzarella & Olive Antipasto Jar

Use good olive oil: Its flavor is central to the recipe. Choose one you enjoy in salad dressing.
Dry the ingredients: Excess water from mozzarella, tomatoes, or herbs can dilute the marinade.
Choose different olives: Buttery green olives and stronger Kalamata olives create a balanced mixture.
Check stuffed olives: Some contain anchovies or cheese, which may affect dietary preferences.
Slice onion thinly: Thick pieces can overwhelm the other ingredients.
Adjust the heat: Start with ¼ teaspoon pepper flakes for a mild version.
Use clean utensils: Always serve with a clean spoon or fork.
Avoid unnecessary oil: Jar shape and ingredient size determine how much is needed; you may not use the full 2 cups.
Remove whole bay leaves: They flavor the marinade but should not be eaten.

📝 Recipe Notes for Marinated Mozzarella & Olive Antipasto Jar

Choosing the mozzarella

Fresh mozzarella pearls give the most convenient bite-size portions. Mini bocconcini also work well. Avoid shredded mozzarella, which does not provide the same texture and can clump in the marinade.

Choosing the vinegar

Red wine vinegar gives a sharper, savory flavor. White balsamic vinegar is usually milder and slightly sweeter. Either works, so choose according to your preference.

Using less oil

For a bowl version, reduce the olive oil to ½ cup and keep the remaining marinade ingredients the same, adjusting salt to taste. Toss everything thoroughly and stir once or twice during refrigerated marinating. This version coats the ingredients rather than submerging them.

Optional additions

A small amount of well-drained roasted red pepper or quartered artichoke hearts can add variety. Keep additions modest so the mozzarella, tomatoes, and olives remain the main ingredients.

Serving suggestions

Spoon drained portions over leafy greens, add them to a sandwich, or serve alongside hummus and toasted pita. For an appetizer board, arrange small bowls of antipasto with bread and sliced vegetables.

❓ Questions & Answers for Marinated Mozzarella & Olive Antipasto Jar

Can I prepare this the night before?
Yes. Overnight refrigeration gives the garlic and herbs time to flavor the mixture. Whole tomatoes generally hold their texture better when prepared ahead.

Why has the olive oil become cloudy or thick?
Olive oil can turn cloudy or partly solidify in the refrigerator. This is normal and does not, by itself, indicate spoilage. Let the serving portion stand briefly and stir gently.

Can I use dried herbs instead of fresh sprigs?
Yes. Omit the rosemary and thyme sprigs and add a small pinch of dried rosemary and approximately ¼ teaspoon dried thyme. Dried herbs are concentrated, so start lightly.

Does the vinegar make the jar safe to store in the pantry?
No. This recipe has not been formulated or tested for shelf-stable preservation. Keep it refrigerated; adding vinegar does not turn it into a canned or preserved product.

Can I use the leftover marinade?
Use a little as dressing for the antipasto within the same refrigerated storage period. Do not save it as a long-term garlic oil or use it to start a new batch.

🧊 Storage & Serving Instructions for Marinated Mozzarella & Olive Antipasto Jar

Refrigerate the jar immediately at 40°F (4°C) or below. Plan to enjoy it within 3 days, and discard any remaining mixture and oil by the end of day 4. Homemade oils containing fresh garlic or herbs require refrigeration and a short storage period. CDC

Label the jar with the preparation date so the storage time is easy to track. Keep the main jar chilled and put out small portions for serving.

No reheating is needed. Briefly temper the serving portion to soften the olive oil, then gently stir. Freezing the assembled antipasto is not recommended for quality because the tomatoes and mozzarella can develop an unpleasant texture.
