What Ingredients do I Need?

Sheet Pan Tomato Soup:

tomatoes – great for heart health and has nutrients to keep your skin glowing

garlic – helps to lower blood pressure and cholesterol levels

yellow onion – adds a nice flavor with the tomatoes when roasted to help break up the acidity

thyme – is known as an antioxidant and anti-inflammatory and adds flavor to the soup

olive oil – to coat the veggies for baking. This one is my favorite!

coconut cream – adds a creamy thicker texture to the soup and breaks up the acidity of the tomatoes

salt and pepper – for seasoning

Grilled cheese:

sourdough bread – or any bread of choice! I prefer sourdough or a whole wheat bread.

cheese of choice – vegan cheddar is what I used!

How do you make Sheet Pan Tomato Soup?

1. Preheat the oven 

2. Prep a baking sheet 

3. Peel onion and cut onion and garlic.

4. Add onion, garlic, all tomatoes, and thyme to the pan. Drizzle on olive oil then season.

5. Roast the veggies.

6. When the veggies are done, add them into a pot with the coconut cream and use an immersion blender to blend or pour the veggies into the blender and blend!

9. Serve and enjoy!

Commonly Asked Questions

  • What type of tomatoes should I use? I used a mix of cherry tomatoes and tomatoes off the vine, but any type will work as long as the measurement is correct.
  • Can this be gluten free? Yep! You can use any type of bread that works for you.
  • Do I need to use fresh thyme? Fresh thyme is best for this Sheet Pan Tomato Soup to get the most flavor, but dried thyme would work too.
  • Will I be able to eat this as leftovers? Definitely! You can reheat the soup for up to 4 days and make sure to make some more grilled cheese to go with it when serving.

Extra Helpful Tips

  1. If you are using a blender to blend the veggies, be cautious of the heat of the veggies and make sure to have the lid of the blender on to avoid a mess.
  2. For cooking the grilled cheese, you can use a skillet. If you want melty cheese, put a lid on the pan to “steam” it.
  3. If you are making grilled cheese croutons, they are best when they are crispy and put right on top of the soup before serving to avoid the croutons getting mushy.

    Soup was fantastic. Really easy. Next time I’ll remove the thyme from the stem before roasting. They didn’t blend well with the immersion blender.5 stars

    How do you add the roasted garlic?Thank you.

    1. Taylor says:

      Hi! Taylor from team HealthyGirl here!
      You can cut the whole clove in half and put it straight on to the baking sheet. When it comes out you will be able to squeeze the clove to get the garlic out.
