Roasted Tomatoes, Onions, With Mozzarella & Cucumbers: A Burst of Summer Flavors

I remember the first time I tasted a combination like this. It was at a small farmer’s market in Tuscany. The air was thick with the scent of sun-baked earth and ripening tomatoes. A local vendor had a simple salad of roasted vegetables, fresh mozzarella, and herbs, drizzled with balsamic. The sweetness of the tomatoes, the sharpness of the onion, and the creamy coolness of the mozzarella – it was a revelation, a perfect encapsulation of summer on a plate. Now, I recreate a version of that magic, capturing the essence of those sun-drenched days in every bite.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 1 hour
• Total Time: 1 hour 15 minutes
• Servings: 4
• Yield: 3 cups
• Dietary Type: Vegetarian

Ingredients

• 1 pint cherry tomatoes
• 1 medium onion, thinly sliced
• 5 garlic cloves
• 1 tablespoon extra virgin olive oil
• ½ tablespoon balsamic vinegar
• ⅓ cup scallion, thinly sliced
• ½ cup bite-size fresh mozzarella cheese balls
• ½ cucumber, cubed

Equipment Needed

• Glass bowl
• Baking sheet

Instructions

1. Preheat your oven to a low 250°F (120°C). This gentle roasting coaxes out the natural sweetness of the tomatoes and onions without burning them.
2. In a glass bowl, combine the cherry tomatoes, thinly sliced onion, garlic cloves, and thinly sliced scallion.
3. Drizzle the extra virgin olive oil over the mixture, ensuring all the vegetables are lightly coated. The olive oil helps with the roasting process and adds a rich flavor.
4. Pour the balsamic vinegar over the vegetables and gently toss to combine. The balsamic vinegar will caramelize in the oven, adding a tangy sweetness to the dish.
5. Spread the mixture evenly on a baking sheet. Avoid overcrowding the pan, as this will steam the vegetables instead of roasting them. If necessary, use two baking sheets.
6. Roast in the preheated oven for 1 hour. The tomatoes should be softened and slightly wrinkled, and the onions should be translucent and beginning to caramelize.
7. Remove the baking sheet from the oven and return the roasted vegetable mix to the glass bowl.
8. While the mixture is still warm, gently mix in the mozzarella cheese balls. The residual heat will cause the mozzarella to melt slightly, creating a creamy texture.
9. Let the mixture cool for about 10 minutes. This allows the flavors to meld together and prevents the cucumber from wilting.
10. Gently fold in the cubed cucumber.
11. Serve immediately or chilled.

Expert Tips & Tricks

• For a deeper, more complex flavor, use a high-quality balsamic glaze instead of balsamic vinegar. Drizzle it over the roasted vegetables just before adding the mozzarella.
• If you don’t have fresh mozzarella balls, you can use cubed mozzarella cheese. However, fresh mozzarella balls are preferred for their creamy texture and delicate flavor.
• To prevent the mozzarella from completely melting, add it to the roasted vegetables just before serving. This will keep the cheese soft and pillowy.
• For a spicier kick, add a pinch of red pepper flakes to the vegetable mixture before roasting.
• If your oven tends to run hot, reduce the temperature by 25 degrees and check the vegetables after 45 minutes.
• Don’t discard the juices that accumulate at the bottom of the bowl. These flavorful juices can be drizzled over salads or used as a base for a vinaigrette.

FAQs (Frequently Asked Questions)

Q: Can I use dried garlic instead of fresh garlic cloves?
A: While fresh garlic is preferred for its robust flavor, you can substitute with ½ teaspoon of garlic powder. Add it along with the olive oil and balsamic vinegar.

Q: How do I prevent the tomatoes from bursting during roasting?
A: Roasting at a low temperature (250°F) helps to prevent the tomatoes from bursting. However, if you’re concerned, you can gently prick them with a fork before roasting.

A: Yes, you can roast the vegetables up to 2 days in advance. Store them in an airtight container in the refrigerator and add the mozzarella and cucumber just before serving.
