Roasting plum tomatoes does more than just concentrate their savory flavor; it actually enhances their nutritional profile. This preparation method is specifically designed to support heart health and blood sugar management by using heart-healthy fats and antioxidant-rich ingredients.
While the recipe suggests peeling them after roasting for a smoother texture, the skins are perfectly edible and contain extra fiber.
Yes, the sugar is optional, but it helps balance the natural acidity of the tomatoes during the long roasting process.
Plum or Roma tomatoes are best due to their low water content, but cherry tomatoes are a great alternative for a sweeter, bite-sized version.
Complement your main course with these nutrient-dense roasted vegetable side dishes that use heart-healthy oils and simple seasonings to bring out the natural, caramelized flavors of garden-fresh produce.

Plum tomatoes (also known as Roma tomatoes) are the ideal candidate for roasting because they have a lower moisture content and thicker fruit walls compared to slicing tomatoes. This allows them to hold their shape in the oven while their sugars caramelize, resulting in a meaty texture and concentrated "umami" flavor that shines in simple preparations.
Recipe yields 6 servings
Preheat oven to 325°. Line a baking sheet with parchment paper.
Slice the tops off the tomatoes and discard. Slice the tomatoes in half lengthwise and lay them flesh side down on baking sheet. Drizzle each tomato with olive oil. Sprinkle salt, pepper and sugar evenly over the tomatoes.
Add a small amount of herbes de Provence to each tomato. Roast in oven for 45 minutes to 1 hour (the tomatoes will shrivel up and lose their liquid when done). When cool, peel skin from back of tomatoes. Serve warm, cold or at room temperature.
Oven roasted tomatoes can be stored in an airtight container or freezer bags in the refrigerator for up to 1 week or in the freezer for up to 6 months.
These tomatoes are a natural partner for Mediterranean dishes. Try serving them alongside grilled fish or as a topper for an Arugula Ricotta Pizza. They also make a fantastic breakfast addition—try them smashed onto Avocado Toast for a nutrient-dense start to your day.
If you don't have Herbes de Provence, a mix of dried thyme, oregano, and rosemary works beautifully.
While olive oil is preferred for heart health, avocado oil can be used for its high smoke point.
The small amount of sugar helps caramelize the acid in the tomatoes; you can omit it or use a pinch of stevia if strictly monitoring sugar intake.
