Roasted Tomato Sauce brings out the true sweetness of tomatoes and transforms even supermarket varieties into something special. I reach for this sauce again and again for pizza nights or quick pasta dishes because the roasted vegetables blend into a rich, velvety texture without any need to peel the tomatoes.

The first time I made this I had an armful of tomatoes on the counter and no idea what to do with them. Now this is my secret to easy homemade dinners that still taste like summer.

Ingredients

  • Ripe tomatoes: look for soft just slightly wrinkled tomatoes for their rich flavor
  • Medium onions: choose firm onions with shiny skins which add depth
  • Garlic: sliced thin for mellow sweetness or more punch if left chunkier
  • Fresh herbs like thyme or oregano: pick fragrant leafy stems for the most aroma
  • Salt and pepper: good quality salt and freshly ground pepper to balance flavors
  • Brown sugar: just a sprinkle if your tomatoes are a bit sour
  • Balsamic vinegar: adds a balancing acidity and a touch of sweetness
  • Olive oil: use extra virgin for a lush mouthfeel and extra flavor

My favorite part is the scent of garlic and onion as they roast in olive oil. It reminds me of making Sunday suppers with my mom where we used whatever herbs we found in her garden for a personal touch.

What You’ll Need to Make This

01 500 g ripe tomatoes, halved

04 1 handful fresh herbs, such as thyme or oregano
05 Salt and freshly ground black pepper
06 1 tsp brown sugar (optional)
07 1 tbsp balsamic vinegar

How to Prepare

Step 01

Preheat the oven to 170°C (150°C fan) or gas mark 3.

Step 02

Place the halved tomatoes, sliced onions, sliced garlic, and fresh herbs in a roasting tin. Season with salt, black pepper, and brown sugar if using.

Step 03

Drizzle balsamic vinegar and olive oil over the vegetables. Stir thoroughly or use hands to ensure even coating.

Step 04

Place the roasting tin on the centre rack and roast until onions are soft, tomatoes have broken down, and contents are caramelized. Stir occasionally and lower the temperature if vegetables begin to darken too quickly. Roasting time varies: cherry tomatoes require 20–30 minutes, larger tomatoes up to 1 hour.

Step 05

Remove any tough herb stems, then transfer the vegetables and all roasting juices to a blender or a deep bowl for a stick blender. Blend to desired consistency.

Step 06

For a very smooth texture, pass the blended mixture through a fine sieve to remove seeds and large pieces of skin.
