Roasted Tomato Soup Ingredients
To make Roasted Tomato Soup, you will need the following ingredients:
- 3.5 lbs heirloom tomatoes
- 2 large yellow onions
- 3 large garlic cloves
- 2 teaspoons fresh thyme, leaves picked
- 3 tablespoons olive oil
- Sea salt and fresh black pepper, to taste
- 4 cups chicken or vegetable broth
- 1 teaspoon apple cider vinegar
Required Equipment
- High-speed blender
- 9 x 13 inch casserole dish or a rimmed sheet pan
- Large soup pot
What Type of Broth Should I Use?
This Roasted Tomato Soup works beautifully with both vegetable and chicken broth. Can I make one request? Regardless of which stock you use in this soup, if you have the time, make your own stock! Homemade stock adds another whole layer of depth to a recipe. I make my own stock all throughout the year and keep a few litres of it in the freezer at all times. The instruction for how I make my chicken stock can be found here.
Step 1—Prep the Soup Ingredients
Preheat the oven to 425℉. Halve the heirloom tomatoes and remove the stems using a paring knife. Peel the onions and garlic cloves, then cut the onions into quarters.
Step 2—Roast the Tomatoes
Transfer the tomatoes, onion, and whole garlic cloves to a 9 x 13 inch casserole dish. Alternatively, you can use a large rimmed baking sheet, but a casserole dish works best. Sprinkle over the thyme leaves, season with salt and pepper, then drizzle in the olive oil. Gently rub the olive oil and seasonings all over the vegetables.
Roast the tomatoes, onion, and garlic in the preheated oven for 45 minutes, rotating the pan halfway through. Roasting the vegetables deepens the flavour, resulting in a luxurious-tasting soup.
Step 3—Blend the Soup
Allow the roasted vegetables to cool slightly, then transfer them to a high-speed blender. Add your broth of choice and blend on high until completely smooth. Depending on the size of your blender, you may have to do this in batches.
Step 4—Heat and Serve
Transfer the blended soup to a large soup pot to reheat. Taste and adjust the seasoning to your liking. Once the soup has come to a simmer, remove it from the heat and stir in the apple cider vinegar.
Serve immediately, or store in the fridge for up to 5 days. You can also store the soup in the freezer for up to three months.
