In a shallow baking dish (11x7 inch works well), immerse the tomatoes in the olive oil, ensuring tomatoes are completely covered. Tuck the basil leaves and garlic into the dish and sprinkle with salt. Bake with 30 minutes, or until the tomatoes are tender, hot and bubbling.
Remove from the oven and let cool to room temperature. Once cooled, transfer the tomatoes and oil to glass jars, making sure oil completely covers the tomatoes, and seal the jars. Store in the refrigerator for up to 1 month.
