Ingredients
- 2 pounds ripe tomatoes (Roma or heirloom, firm but ripe)
- ¼ cup good quality extra virgin olive oil, divided
- 3 cloves garlic, thinly sliced
- 1 teaspoon flaky sea salt
- ½ teaspoon freshly ground black pepper
- 1 tablespoon fresh basil leaves, finely chopped
- 1 teaspoon sugar (optional, enhances caramelization)
Instructions
- Preheat your oven to 275°F (135°C). Line a baking sheet with parchment paper for easy cleanup and to prevent sticking.
- Prepare the tomatoes: Wash and dry thoroughly.Slice medium-sized tomatoes in half lengthwise. For larger heirlooms, cut into thick wedges to maintain juiciness during roasting.

Chef’s Notes: Tips for Success
- Choose firm, ripe tomatoes: Roma tomatoes are often ideal for roasting due to their low moisture and dense flesh that caramelizes beautifully. heirlooms add vibrant color and nuanced flavor but trim excess moisture with a paper towel if too juicy.
- Low and slow is key: Roasting at a lower temperature for longer allows natural sugars to develop slowly,enhancing sweetness without drying the tomatoes out.
- Adjust sweetness thoughtfully: If your tomatoes are very acidic,a pinch of sugar helps balance the flavor without overpowering.
- Make ahead: These tomatoes are a fantastic make-ahead ingredient. Keep refrigerated and bring to room temperature before serving for best flavor.
- Experiment with herbs: While basil is classic,try adding rosemary or thyme for a different herbal note that complements the olive oil.
Serving suggestions
- On toasted rustic bread: Pile thick slices of slow-roasted tomatoes on crispy baguette rounds and finish with a sprinkle of flaky sea salt and cracked pepper for a vibrant bruschetta.
- In salads: Toss with mixed greens, burrata cheese, toasted pine nuts, and a splash of balsamic vinegar for an elegant salad centerpiece.
- With pasta: fold into freshly cooked pasta with grated Parmesan, fresh basil, and a drizzle of olive oil for an effortless gourmet meal.
- As a pizza topping: Scatter these tomatoes over your dough before baking to infuse deep roasted flavor into every bite.
- Accompany roasted meats: Serve alongside grilled chicken or lamb to add a sweet and acidic contrast that brightens the plate.

Q&A
Q&A: Unlocking Flavor – Slow-Roasted Tomatoes with Olive Oil & Basil
Q1: Why choose slow-roasting for tomatoes instead of other cooking methods?
A1: Slow-roasting is like a flavor meditation for tomatoes.It gently concentrates their natural sugars,transforming ordinary tomatoes into deep,caramelized jewels bursting with complexity. Unlike quick roasting or sautéing, slow-roasting melds the acidity and sweetness into a harmonious flavor symphony, unlocking layers that raw or fast-cooked tomatoes simply can’t achieve.
Q2: What role does olive oil play in slow-roasting tomatoes?
A2: Olive oil isn’t just a cooking medium here-it’s a flavor enhancer and a texture transformer. It kisses the tomatoes with a silky richness, helping to soften their flesh while amplifying the aroma. The choice of a high-quality, extra virgin olive oil adds fruity and peppery notes, creating a luscious mouthfeel that beautifully balances the roasted tomatoes’ tang.
Q3: How does basil complement the slow-roasted tomatoes?
A3: Basil is the bright,herbal counterpoint that lifts the roasted tomatoes from indulgent to inspired. It’s fresh, slightly sweet, and peppery flavor cuts through the olive oil’s richness and the tomatoes’ caramelized depth, adding a garden-fresh vibrancy. adding basil either before roasting to infuse or after to garnish keeps the dish lively and fragrant.
Q4: Can you use any type of tomato for this recipe?
A4: While you can experiment, plum varieties like Roma or San Marzano shine brightest due to their denser flesh and lower water content, which helps them roast evenly without turning mushy. Cherry tomatoes can also work, bursting into sweet explosions of flavor but producing a different, juicier texture.
Q5: How long should the tomatoes be slow-roasted, and at what temperature?
A5: Patience is key. Slow-roast tomatoes at a gentle 275-300°F (135-150°C) for about 1.5 to 2 hours. This low-and-slow approach dehydrates them just enough to concentrate sweetness and develop that luscious, velvety texture without burning. The extended time allows all their natural sugars to caramelize slowly, inviting a richer depth of flavor.
Q6: What dishes pair well with slow-roasted tomatoes?
A6: These flavor-packed tomatoes are culinary chameleons. toss them into pasta, spread on crusty bread as a bruschetta topping, fold into salads, or dollop over grilled meats and seafood. Their intense sweetness and herbal freshness can elevate a simple omelet or even jazz up a cheese board.
Q7: Can slow-roasted tomatoes be stored and used later?
A7: Absolutely! Once fully cooled, store them submerged in olive oil in an airtight container in the fridge for up to one week. You can also freeze them for longer storage. Preserving them this way means you’ve always got a jar of sunshine-ready flavors on hand to brighten your dishes.
Q8: Any tips to make the ultimate batch of slow-roasted tomatoes?
A8: Yes! Use ripe but firm tomatoes for best results. Avoid overcrowding the pan to allow even roasting and evaporation. Season simply with sea salt and freshly cracked pepper so the tomatoes’ natural flavors shine. And don’t rush-let time work its magic slowly and deliciously.
