Equipment

  • 1 Cutting board
  • 1 Knife
  • 1 baking tray lined with parchment paper
  • 1 Oven 356°F (180°C)
  • 1 Food processor or immersion blender
  • 1 airtight container for storage

Ingredients

  • 5 medium tomatoes
  • 1 bell pepper
  • 1 red chili pepper optional
  • 1 onion
  • 6 cloves of garlic
  • 2 carrots
  • 2 tbsp of olive oil
  • salt and pepper to taste
  • 2 or 3 tbsp dried or fresh herbs to taste basil, thyme, marjoram, rosemary, and sage

Instructions

  • Preheat your oven to 356°F (180°C).
  • Wash and slice the tomatoes, red chili pepper, and bell pepper, then place them on a baking tray lined with parchment paper.
  • Chop the onion and carrot and add them to the tray as well.
  • Drizzle the vegetables with olive oil and sprinkle with dried herbs, salt, and pepper to taste.
  • Roast in the preheated oven for about 1 hour.
  • Once the vegetables are nicely roasted, transfer them to a food processor or use your immersion blender and blend into a smooth sauce. Taste and adjust the seasoning if needed.
  • Let the sauce cool completely before transferring it to an airtight container.

Notes

  • How to Store: Let the sauce cool completely before transferring it to an airtight container. Store in the fridge for up to 1 week or freeze for up to 3 months.
  • Blending Tip: For an ultra-smooth texture, blend the sauce while it’s still warm, but not hot. Be careful if using a high-speed blender—don’t fill it to the top and hold the lid firmly.
  • Herb Options: Use whatever herbs you love! Dried Italian herbs work well, or add fresh basil at the end for a brighter flavor.
  • Spice Level: The red chili pepper adds a mild kick. Feel free to leave it out or swap it for something spicier if you like more heat (like chili flakes).
  • No Food Processor? A stick (immersion) blender works just as well—just blend everything directly in a deep bowl or pot.
  • Serving Ideas: This sauce is perfect for pasta, pizza, lasagna, or as a base for soups and stews.
