    My Soup Obsession!

    We love all kinds of soup in our home. But I personally have a soft corner for the cream-style ones like my Instant Pot Roasted bell pepper and tomato bisque, Roasted butternut squash and lentil soup, Instant Pot Broccoli lentil soup, and now another one to join this collection is the fall-inspired Instant Pot Thai Butternut Squash Soup that is infused with red curry, coconut milk, and aromatics.

    It’s so yummy and satisfying; guaranteed to warm you inside out! Thai food lovers will love this soup!

    And since the temperatures have started to drop, more soups are heating up, so grab an apron, and let’s get cooking!

    Why we love this Instant Pot Thai Butternut Squash Soup

    If you like Thai food and squash, you will love this butternut squash Thai soup. because it’s —

    » Quick and Easy — This soup comes together in less than an hour but tastes as if it’s simmered all day long. The only tedious part is cutting up the squash. It’s a little bit of labor-intensive work ( which I think), but it’s so worth it. 

    » Little hands-on cooking — Thanks to my Instant Pot (electric pressure cooker), making soup is the best option. Sauté a few ingredients, toss in peeled and cubed butternut squash, pressure cook, blend, and finally, add coconut milk. That’s it – your creamy and perfectly pureed soup is ready. As a bonus, pressure cooking preserves the essential nutrients and vitamins, and the flavor is like soup was slow-cooked for hours. 

    » Vegan and Gluten-free — The recipe, as written, is gluten-free, nut-free, vegan with due thanks to the use of coconut milk. Imagine all that creaminess and luscious texture in a soup without a drop of cream; this is what I love about coconut milk. It adds a velvety texture to any soup without adding extra carbs. 

    » Make great leftovers — Like all other soups, the flavor of this Thai butternut squash deepens in flavor if allowed to sit. So, prepare this soup a day or two in advance, and it will tastes even better the next day and the day after that.

    » Reminds you of fall — As the seasons change, I love to make this soup because it is made with my favorite autumn ingredient, butternut squash, and has all the traditional smells that will remind you of cold air, falling leaves, and light jackets every time you sip on it.

    Ingredient List

    Ingredient list for Instant Pot Thai Butternut Squash Soup

    This butternut squash Thai soup comes together quickly with no complicated ingredients or procedures to follow. 

    » Olive oil —  I have used olive oil; however, you can add any mild flavor oil of your choice.

    » Onions and Ginger- garlic paste — This Thai butternut squash soup is flavored with fresh garlic, onions, and ginger that build the foundation of this soup. 

    » Thai Red Curry Paste — I have used ‘Thai Kitchen Gluten-free Red Curry Paste.’ Vegan red curry paste is readily available at your nearby grocery stores. It provides a well-rounded depth of flavor to this soup that can’t be matched. The spice level of the Thai curry paste depends on the brand you use; therefore, add accordingly. The one that I have used is mildly spiced. 

    » Butternut Squash — This nutty and sweet butternut squash is the building block of this recipe. 

    Substitute  — You can use frozen diced squash or pre-cut squash to save time. Or you can use pumpkin, sweet potato, or carrots as a substitute – they too work perfectly for this recipe.

    » Lemon Grass — This long leek-like herb has a strong lemon aroma, and it lends Thai soup a unique flavor. You could either use Kaffir lime leaves as a substitute or increase the lemon zest in the recipe. 

    » Sugar — To balance out the flavors. 

    » Lemon Zest + Lemon juice — Thai-inspired soups taste amazing with lemon zest in it. Also, butternut squash is sweet, so a little bit of lemon zest adds the perfect amount of kick. Likewise, a hint of freshly squeezed lemon juice will deliver the best flavor. 

    » Water — To give my Thai butternut squash soup the right consistency, I have used water, but feel free to use vegetable stock as a substitute.

    » Coconut milk — To keep it as low-calorie soup, I have opted for low-fat unsweetened coconut milk. This plant-based milk is a staple in Thai cuisine as it adds a light nutty-sweet flavor and gives the dishes a smooth, rich, and creamy texture. 

    » Garnishes — I have topped my soup with sunflower seeds, scallions, chopped cilantro, and some crushed red pepper flakes. A dash of chili flakes complements the Thai soup with just the right spiciness, which is not too overpowering.

    Substitute  — You can substitute chili flakes and scallions in this recipe with toasted peanuts if you’re not allergic.

    How to make Instant Pot Thai Butternut Squash Vegan Soup

    This section walks you through a detailed step-by-step recipe with pictures. For the FULL, printable recipe card, please scroll down to the bottom of this post.

    » Peel the squash — Clean butternut squash with a wet towel to remove dirt or grits. Poke holes in the squash. Microwave on HIGH for 3-4 minutes. Carefully remove the squash from the microwave. Allow it to cool.

    Once the butternut squash is cool enough to handle, peel the outer layer with a peeler. Slice the top and end off. Using a spoon, scoop out the seeds and flesh attached to the seeds. Cut the butternut squash into cubes and set it aside. 

    PROTIP — You don’t even have to evenly dice the squash when cooking in Instant Pot because it will cook perfectly under pressure. When using fresh butternut, cut the squash in half, peel off, then slice in big chunks that can nestle in an Instant Pot insert. That’s it. It still cooks well, is soft, and purees perfectly.

    PROTIP — Use a sharp vegetable peeler and a sharp knife to speed up the process to cut up the squash.

    Peel the Butternut Squash

    » Cook the aromatics — Turn the Instant Pot to ‘Saute mode.’ Once it displays ‘hot,’ add oil to the insert. Add ginger-garlic paste and sauté for a minute or until fragrant. Add chopped onions. Cook for 2-3 minutes until onions are soft and translucent.

    Add Thai Kitchen Gluten-free Red Curry Paste and cook for another 2 minutes or until the curry paste deepens in color.

    Cook the aromatics

    » Add Squash, Seasonings and Cook the soup — Add butternut squash, lemongrass, salt, pepper, lemon juice, lemon zest, and water. Mix everything until combined. Don’t forget to deglaze the base of the insert. 

    PROTIP — Deglazing the insert removes all the brown bits stuck to the base. Scrape everything from the base to prevent the burn message. 

    Turn the Instant Pot off. Close the lid and seal the pot. Press the Manual or pressure cook button and cook the Instant Pot Minestrone Soup for 8 minutes on HIGH.

    PROTIP — It will take about 10 minutes for the pressure to build than the actual cooking time.  

    Add butternut squash

    » Add Coconut milk — Once the cooking time has elapsed, allow the pressure to release naturally for 5 minutes, turn the steam valve to the venting position to release the remaining pressure. When the pin drops, carefully open the lid.

    Remove the lemongrass stalks from the soup and discard. Add coconut milk, lemon zest, and give it a good stir. Cover the insert and allow the soup to simmer for 10 minutes on Sauté setting. 

    Add coconut cream to soup

    » Blend the soup — Turn off the Instant Pot and blend the soup on low speed at first, and then increase the speed and blend continuously until you have a completely smooth purée.  Adjust the seasonings if needed. Garnish with cilantro leaves, scallions, and serve warm.

    RECIPE NOTES

     
    STORING
    Instant Pot Thai Butternut Squash Soup will last for about 3-4 days in the refrigerator in an airtight container. The soup becomes tastier and richer as it soaks in all the beautiful flavors.
    Instant Pot Thai Butternut Squash Soup reheats beautifully. To reheat the next day, transfer the soup to a microwave-safe dish, cover with a lid, and microwave at 1-minute intervals until heated through. 
    You can even reheat the soup on the cooktop over medium heat. Keep stirring the Thai Butternut Squash Soup until heated through.
     
    FREEZING
    I like to make a big batch of soups and stews and freeze them for future dinners. Frozen soups are perfect for adding to your meal plan, bake some fresh bread to go along with it, and dinner is sorted!
    You can freeze this Thai butternut squash soup for up to 3 months. When ready to serve, thaw the soup overnight in the fridge, then reheat over the cooktop or in the microwave, as mentioned above.
