Garlic – A whole bulb of fresh garlic is the secret to that irresistible, taste. Trust me, it’s chef’s kiss!

Onion – both yellow onion or sweet onion work great!

Seasoning – Italian seasoning, salt, and pepper, are all you need to enhance those roasted flavours.

Broth – Use chicken broth or vegetable broth, both are equally delicious.

How to make roasted garlic tomato soup 

Chop. Start by quartering your onion and tomatoes, and cutting the top off the garlic bulb. Arrange everything on a large sheet pan lined with parchment paper for easy cleanup.

Season. Drizzle olive oil generously over the veggies, especially the garlic bulb—this helps it roast to perfection. Sprinkle with Italian seasoning, salt, and pepper for flavour!

Roast the vegetables. Pop the sheet pan into a 350°F oven and roast for about 40 minutes, stirring halfway through to ensure the veggies cook evenly.

Simmer. Transfer the roasted vegetables to a large pot, add your broth, and bring to a gentle simmer. Cover and let it simmer for about 15 minutes to let those flavours meld.

Blend. Blend the soup until silky smooth. You can use a countertop blender or an immersion blender for ease/convenience.

Enjoy! Ladle this cozy roasted garlic tomato soup into bowls, pair it with a toasty grilled cheese, and savour every spoonful!

Tips and Tricks

  • For an Extra Smooth Soup: After blending, the soup will still have some texture from the tomato seeds and skins. If you prefer a velvety smooth soup, strain it through a fine mesh sieve. Keep in mind, though, this will reduce the fiber content of this veggie-packed dish!
  • Add Some Spice: Want to kick it up a notch? Sprinkle chili flakes on top for a touch of heat and extra flavor!
  • Make it creamy: For an even creamier soup, swirl in some plain Greek yogurt before serving. It’s a simple way to make it feel extra indulgent!
