Get your love affair on with fall and add this roasted Heirloom Tomato Soup to the mix. Fresh herbs will kiss your tastebuds with every bite and remind you of simpler times. The bold and rich tomatoes will wrap you in a blanket of flavor and comfort, only igniting your love of colder weather further.
If there’s one thing that fall could never live without is soup. Soup seems to define fall as a season along with other comfort recipes like Homemade Apple Pie Filling drizzled with Vegan Salted Caramel Sauce. Of course, you can’t live without chili and all those amazing pumpkin desserts. Pair those with a comfy sweater, leggings, and a cup of cider and you’re in for the best day of your life.
Tomato soup definitely should get the recognition it deserves as one of the most popular soups in existence. It’s so easy to make and is one of the best choices when it comes to being paired with other foods. I still remember those chilly nights as a child with a big bowl of tomato soup and a sandwich to dip it in. Ahhh, those were simpler and amazing times. The power of tomato soup is in the memories it can make come rushing back.
How to Make Heirloom Tomato Soup
- Roast – Preheat the oven to 350 degrees. Add the tomatoes, garlic, onion, and thyme to a dish. Drizzle with olive oil and roast for 1.5-2 hours.
- Simmer – Discard the thyme sticks and add the tomato mixture and broth to a soup pot.
- Blend – Use a blender to puree the ingredients in the pot.
- Serve – Adjust seasonings as preferred, garnish, serve, and enjoy!
Soup Tips and Variations
- Storage – Store in an airtight container in the fridge for up to 5 days. Store in an airtight container in the freezer for up to 3 months.
- Reheating – Reheat in a small pot over the stove. You can also use the microwave as a quicker option.
- Topping suggestions – This soup is known for being the perfect dish to receive all the toppings or additions. Here are some of my favorites: crispy onions, vegan cheese, crumbled veggie crackers, saltines, fried jalapenos, etc.
- Add cashew milk – Tomato soup is delicious when made just a bit creamy. A splash of homemade cashew milk or coconut cream will do the trick.
- Make it on the stove top – If you don’t want to take the time to roast your tomatoes, you can make it all on the stove top. Saute the onion and oil in a large stock pot. Once translucent, add in the garlic and cook for a minute. Add the tomatoes, thyme, and pepper flakes and cook until tomatoes burst. Add the rest of the ingredients, simmer for about 20 minutes, and enjoy!
- Use a blender – To get a super smooth consistency with your soup, transfer it all to a blender instead of using the immersion blender. The immersion blender makes it a bit chunkier.
- Use other types of tomatoes – I used red heirlooms, but you can, of course, mix them up or make a golden tomato soup like I did when making the heirloom tomato sauce. The sun gold cherry tomato varieties make a super delicious variation as well.
- What to serve with heirloom tomato soup? – A vegan grilled cheese sandwich is always my first go-to with this classic soup. However, you could also do fresh basil, chives, parsley, homemade crusty bread, focaccia, a dollop of vegan sour cream, or classic Italian bruschetta (A.K.A. the real garlic bread).
Heirloom Tomato Soup FAQ
Can Tomato Soup Be Frozen?
You bet tomato soup can be frozen! It’s actually a really great recipe option for making large batches and freezing for future dinners. I love it for meal prep as well. I wouldn’t freeze it for any longer than 3 months as that’s kind of my limit for frozen food. After that point, the taste starts to change and I’m not all about it.
Is Tomato Soup Good for You?
It’s a very healthy option, whether you’re looking for weight loss or just to put better ingredients in your body in general. Tomatoes and fresh herbs are all packed with the vital nutrients your body needs and craves on a daily basis. Hello Lycopene! The only thing you’ll want to watch out for is the acidity of the tomatoes as that can bother some people’s stomachs. They’re also a nightshade which can exacerbate some conditions such as IBS and Crohn’s.
