Slow Roasted Tomatoes Ingredients

For the Confit
• Roma Tomatoes – Essential for their thick walls and meaty texture; substitute with San Marzano or oblong heirloom tomatoes for similar results.
• Garlic – Adds robust flavor; very finely diced increases texture integration, or blend with oil for a smoother finish.
• Salt – Critical for flavor enhancement and moisture extraction; adjust according to taste.
• Fresh Oregano – Contributes aromatic herbaceous notes; can be substituted with dry oregano or Italian seasoning.
• Fresh Basil – Adds freshness; may be replaced by other herbs like parsley if necessary.
• Dried Thyme – Provides earthy depth; optional depending on preference.
• Olive Oil – Primary fat for roasting, enhancing flavor; can substitute with canola or sunflower oil for a milder taste.

For Serving
• Crusty Bread – Perfect for spreading the confit on; choose a good quality artisan loaf for the best experience.
• Grilled Meats – Complement the confit beautifully as a vibrant topping; try it with chicken or fish for an exquisite flavor pairing.

How to Make Slow Roasted Tomatoes

Prepare Tomatoes: Blanch the Roma tomatoes in boiling water for about 15-20 seconds until the skins start to peel. Quickly cool them in ice water for easy peeling. Cut them lengthwise into 1-inch thick halves and gently squeeze out any excess liquid.
Drain Tomatoes: Place the cut tomatoes on kitchen towels or a wire rack. Sprinkle them with salt, allowing them to sit for 20-30 minutes. This step helps extract more moisture for that jammy texture.
Make Garlic & Herb Oil: In a small bowl, mix the minced garlic with olive oil and your chosen herbs. Let this mixture sit for at least 5 minutes to infuse the flavors together beautifully.
Stuff Tomatoes: Arrange the drained tomato halves cut-side up on a parchment-lined baking sheet. Generously drizzle the infused garlic oil into each tomato, ensuring they’re well-coated.
Roast: Preheat your oven to 120°C (250°F). Bake the tomatoes for 4-6 hours, keeping a close eye on them. They should be reduced and caramelized, achieving a soft, jam-like consistency that’s rich and aromatic.

Optional: Serve these slow roasted tomatoes with a sprinkle of fresh basil on top for an extra burst of flavor.

Expert Tips for Slow Roasted Tomatoes

Choose Quality Tomatoes: Use ripe, firm Roma tomatoes for the best flavor. Overripe or soft tomatoes may turn mushy during roasting.
Proper Draining: After cutting, ensure tomatoes drain adequately. Excess moisture can hinder proper caramelization, resulting in a less desirable texture.
Infuse Flavors: Allow the garlic and herb oil to sit longer if possible—this enhances the flavors that will permeate the slow roasted tomatoes.
Watch the Oven: Oven temperatures can vary; check the tomatoes after 4 hours. They should be soft but not completely dried out—aim for that jam-like consistency.
Storage Savvy: Store your flavorful confit in an airtight container submerged in olive oil to maintain freshness, and always keep it refrigerated for up to one week.

Make Ahead Options

These slow roasted tomatoes are a fantastic choice for meal prep! You can prepare the tomatoes up to 24 hours in advance by blanching and peeling them, then refrigerating them until you’re ready to roast. To maintain their quality, sprinkle them with salt and let them drain on kitchen towels as directed; this prevents excess moisture before roasting. When you’re ready to enjoy, simply mix your garlic and herb oil, stuff the tomatoes, and roast them for 4-6 hours in the oven. This makes for a simpler, less hectic cooking experience and ensures rich, jammy flavors that develop beautifully over time!

Smoky Twist: Incorporate smoked paprika into the garlic and herb oil for a rich, smoky flavor that pairs beautifully with the sweetness of the tomatoes.
