Slow-Roasted Tomatoes with Feta, Olives and Pine Nuts

Ingredients

  • medium plum tomatoes, halved lengthwise and seeded
  • /4 teaspoons salt
  • /2 cup pine nuts
  • cups crumbled feta cheese
  • (3 ounce) package cream cheese
  • /3 cup coarsely chopped kalamata olives
  • teaspoons dried oregano
  • tablespoons extra-virgin olive oil

Instructions

  1. Step 1

    I begin by prepping the tomatoes. After halving and seeding them, I sprinkle salt over the cut sides and place them face down on a wire rack over a baking sheet. Let them drain for about 30 minutes—this step draws out excess moisture, ensuring a firmer texture when roasted. While the tomatoes drain, lightly toast the pine nuts in a dry skillet over low heat, stirring constantly until they turn golden and fragrant, about 3-4 minutes. Set aside to cool. Preheat your oven to 325°F (160°C). In a mixing bowl, blend the feta, cream cheese, chopped olives, oregano, and toasted pine nuts until well combined. The mixture should be creamy and chunky. Once the tomatoes have drained, pat them dry with a paper towel and arrange cut-side up on a parchment-lined baking sheet. Spoon approximately 2 tablespoons of the feta filling into each tomato half, mounding it slightly. Bake for 30 minutes, or until the tomatoes are tender but still hold their shape. The cheese will be soft and lightly golden. After removing from the oven, brush the tops with olive oil while still warm. These can be enjoyed hot, at room temperature, or even chilled—they’re versatile and bursting with Mediterranean flavor.

Chef's Tip

I find that letting the tomatoes rest for 10 minutes after baking allows the flavors to meld beautifully. For an extra pop, I sometimes sprinkle a pinch of red pepper flakes before serving.

Storage Tips

Store any leftover roasted tomatoes in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 300°F oven until warm, or enjoy them cold straight from the fridge. I avoid microwaving as it can make the tomatoes soggy.

Variation Tips

Swap feta for goat cheese to add a tangier kick, or use sun-dried tomatoes in place of fresh for a more intense flavor. These stuffed tomatoes pair beautifully with a crisp arugula salad or alongside grilled chicken skewers for a heartier keto spread.
