Tomato and Roasted Garlic Soup

Tomato Roasted Garlic Soup is a classic tomato soup recipe with the addition of roasted garlic. Perfect for dipping with a grilled cheese sandwich.
Sometime late last week, BeeBop and I were watching television one night. Or rather, I was watching television and BeeBop was chatting with some of his author friends on Twitter. One of his Twitter-mates was asking for a recipe for tomato soup with roasted garlic. He thought surely I had such a recipe but turns out I didn’t!

But how good does that sound? Tomato with roasted garlic? Yum. I told BeeBop to tell his friend to give me until the weekend and I’d come up with one. Et voila – Tomato Roasted Garlic Soup!
This soup is so perfect for dipping with a grilled cheese sandwich. Or, as you can see in the photo, with Cornmeal and Scallion Fritters.

Let’s Go Step-by-Step
I always like to show you the photos and step-by-step instructions for my recipes to help you picture how to make them in your own kitchen. If you just want to print out a copy, you can skip to the bottom of the post where you’ll find the recipe card.
Roast the Garlic

Preheat the oven to 425 degrees.
Remove any loose papery skin from the outside of the head of garlic (this is to prevent burning during cooking). Cut a slice from the top of the head to expose the cloves.
Place the garlic on a square of aluminum foil (lined with parchment if desired, but optional). Drizzle with the olive oil and sprinkle with a pinch of salt and pepper.
Wrap the garlic in the foil and place in the oven to bake. Start checking the garlic at 40 minutes and check every 10 minutes until done. Remove from the oven and allow the garlic to cool before handling.

COOK’S TIP
You’ll know the garlic is done when one of the cloves in the center feels soft all the way through when pierced with a paring knife. Even after the garlic soft, you can continue roasting until you get a very dark golden color for a deeper caramelized flavor. The exact cooking time will depend on the variety, size, and age of your garlic.
Also, keep in mind that you should (1) remove the excess papery skin and (2) use sufficient olive oil to prevent burning while cooking.
Remove the cloves from the skin of the garlic by gently pressing the sides of the head of garlic. Be sure to extract all the garlic cloves.
Note: you can roast several heads of garlic together and store any leftovers in the refrigerator for up to one week.
To Make the Soup

Add the oil and butter to a large Dutch oven or soup pot over medium-low heat. When the butter is melted add the onion and cook, stirring occasionally, unto soft but not browned, about 7-8 minutes.
Add the flour and stir to coat the onion. Cook for an additional 2-3 minutes, stirring frequently.

Add the tomatoes with their juice, chicken broth, garlic, salt, and pepper. Roughly tear the basil leaves and add them to the pot.
Increase the heat to medium-high and bring the soup to a simmer while stirring to make sure the flour is not sticking. Reduce the heat to low, cover and cook for 40 minutes.

Puree the soup with a hand-held stick blender or in small batches in a regular blender. Taste for seasoning and adjust if needed.
Serve warm with a dollop of sour cream if desired.

Miss Lana, I really enjoy your blog, thank you for sharing all your wisdom with us! Please tell me how to find the recipe the 2 yummy looking cornbread bites(?) or whatever they are, that are on the plate by the tomato soup bowl. Many thanks!
Hi Kathleen – those are Cornmeal Scallion Fritters and you’ll find the recipe for them here: https://www.lanascooking.com/cornmeal-scallion-fritters/
Gosh, this looks and sounds delicious! I love tomato soup, but I’ve never made it homemade. Thanks for sharing. Hugs!
Kelly, you won’t believe how much better the homemade kind is! Do give it a try – it’s really easy.
Hi, Lana. Thank you so much for this recipe. We can’t wait to try it! Once we make it, I will be sure to tell Bill and you how much we love it!
Kim
We really enjoyed it! Hope you do, too.
That looks wonderful! I think that we are going to have one more spell of cold weather this week. This will be just the ticket for a comfy supper.
Miss P
I cannot wait to try this soup! Anything with roasted garlic has to delicious!
Roasted garlic is just so delicious, isn’t it? It’s really fantastic in this soup with the tomatoes and basil. You could even increase it to 2 whole heads if you’re a big garlic fan.
Two soups that were life changing when made from scratch. Tomato and Mushroom. SO good. I actually think I’ve also made a tomato and roasted garlic soup but if not I will; I actually have the garlic already done just waiting for an opportunity. Looks so good right now; I need some comfort food bad!
I’d add one more to your list, Barb – potato soup. Absolutely no comparison with any purchased version. I always think soup first when I want comfort food :-)
