Instant Pot Fresh Tomato Basil Soup
When we were in New Orleans a couple years ago we went to a little hole in the wall restaurant near our hotel for a quick dinner. There were 14 of us, and only one waitress in the entire restaurant. I felt bad for her.
I wasn't all that hungry so I ordered a bowl of tomato soup. I don't know what I was expecting, but wow! It was the most delicious bowl of tomato soup I had ever eaten!
I set out to try and recreate that flavor using my garden fresh tomatoes, fresh basil, and my Instant Pot®. It was pretty easy, and I came up with two ways to make it.
I had a mixture of tomatoes from my garden. This is my end of season crop, along with the fresh basil I had planted with the tomatoes.
The first version of my Instant Pot Fresh Tomato Basil Soup recipe is my favorite. It involves roasting the tomatoes and a head of garlic together before the pressure cooking. The tomatoes get sweeter, and the roasted garlic is richer and sweeter as well. If you have the extra hour, I highly recommend it!
The second version of my Instant Pot Fresh Tomato Basil Soup recipe is to add the chopped tomatoes to the sautéd onions and garlic, which you do in the pressure cooker on the Sauté setting. It's easier, and you will still get a delicious tomato basil soup. You will cook this version a little longer so the skins have more cook time to get soft.
Both versions of Instant Pot Fresh Tomato Basil Soup yield a delicious soup. The roasted tomatoes & garlic are my favorite, but I'll take either one!

- 4 lbs Fresh Tomatoes, (roasted or fresh) cut in half
- ¼ cup plus 2 Tbsp Olive Oil, divided
- 4 tsp Kosher Salt, divided
- 2 Tbsp Butter
- 7 cloves Garlic, (roasted or fresh) chopped
- 2 cups Onion, chopped (about 2 med onions)
- ¼ tsp Red Pepper Flakes
- 1 sprig Rosemary
- 1 tsp Fresh Thyme Leaves
- 1 cup packed Fresh Basil Leaves
- ½ tsp Pepper
- 1 ½ cups Chicken Broth, low sodium
- 1 Parmesan Rind (optional)
Heat oven to 400° F.
Slice the tomatoes in half and lay skin side down on a baking sheet.
If you want to roast your garlic, cut the top off of a head of garlic bulb and set it on the baking sheet with the tomatoes.
Pour the ¼ cup of olive oil and 3 tsp Kosher salt over the tomatoes. Toss to coat all of the tomatoes and the garlic bulb (if roasting garlic).
Roast in oven for 40-50 minutes. Then remove from oven and set aside (keep it all on the baking sheet).
If you roasted the garlic, remove the roasted cloves from the bulb and set aside so they are ready to add to the soup.
Turn on the pot's Sauté setting. When it is hot, add the remaining 2 Tbsp olive oil and the butter. Add in the onions and cook, stirring occasionally, until translucent.
Add the garlic (roasted or fresh), and red pepper flakes. Stir and sauté for about 30 seconds.
Add the tomatoes (and all of the juices from the pan, if roasted), the remaining 1 tsp salt, rosemary, thyme, and basil leaves, pepper, chicken broth and parmesan rind, if using. Stir.
Put the lid on the pot and set the steam release knob to the Sealing position. Turn off the Sauté setting and press the Pressure Cook button or dial, then the +/- button or dial to select 8 minutes (if using roasted tomatoes), or 20 minutes if using fresh.
When the cook cycle is finished, turn the pot off so it doesn't enter the Warming cycle. Let the pot sit undisturbed for 15-25 minutes to naturally release the pressure. Then turn the steam release knob to the Venting position to manually release the remaining steam/pressure.
Open the lid and gently stir the soup. Remove parmesan rind, if using. Use an immersion blender to smooth the soup, but not too much, unless you want a completely smooth texture.
Taste and adjust salt, if needed.
Serve hot with some crisp croutons, extra fresh basil leaves, parmesan, or sour cream.

i'm in the midst of making two batches right now! question: how long would you cook a double batch (i roasted the tomatoes). assuming i can fit everything into our instant pot, it'd be much easier to do it once!
also, 3 tsp of salt seemed like an awful lot to sprinkle over the tomatoes before roasting them so i just used 1 tsp and figured i could always add more later if necessary. is amount listed in the recipe accurate or is it a typo?
Hi, I would keep the cook time as written. As for the salt, the 3 tsp is correct.
Made this last night, I halved the recipe because I only had 2lbs on tomatoes, roasted them with the garlic and added a couple celery stalks and a carrot because I had them. It turned out AMAZING. My husband hate on bite and just said "oh yeah this is the stuff". Served it with grilled cheese with ham on sour dough and it was such an impressive meal. Thanks for the recipe! I will definitely be making it again and again as the weather gets colder!
This was our supper tonight! Amazingly delicious way to use up fresh tomatoes and basil. I want to try it with frozen tomatoes too. I added a tsp. of sugar.
That's great! Thank you.
2 quick questions:
1. Can I freeze this if I make a really big batch?
2. Can I use a regular blender if I don't have an immersion blender?
Yes and yes. Be very careful when using a blender of food processor. Reheat gently when you do.
This is a fantastic recipe, Sandy. Glad to have found it. Fresh tomatoes and all of the herbs are in season here in the West Indies and I made it twice this month. My husband made the stock which is sodium free, so the rind added just a hint of salt. The only tweaks I made were to add some crushed fennel seeds and a bit of Smoked paprika. Thanks for such a great roasted tomato soup. Will be checking your other recipes too!
PS This is also great served chilled.
That's great, Denise! Thank you for the great tips, and the kind review!
This recipe sounds delish! I am going to make it tonight. How long would you cook in the Instant Pot if you are substituting canned tomatoes?
Made this last night using the fresh tomato method and it came out great, actually just tasted it again and it tastes even better! I used vegetable stock just because and I love it! Thanks for the recipe! ❤️
That's great, Leah! Thank you. I'm so anxious to plant my tomatoes this spring!
