Why Butternut Squash Shines in Soup

Butternut squash is a nutritional powerhouse, rich in vitamins A and C, fiber, and antioxidants. Its naturally sweet and nutty flavor intensifies beautifully when cooked, making it an ideal base for a creamy soup. When choosing a butternut squash, look for one that is firm, heavy for its size, and free of soft spots or blemishes. The skin should be uniformly tan. While fresh butternut squash offers the best flavor, pre-cut squash can be a convenient time-saver.

Mastering the Art of Cutting Butternut Squash

Many home cooks shy away from fresh butternut squash due to the perceived difficulty of preparing it. While its tough skin and dense flesh can seem intimidating, with a few simple steps and a sharp knife, you’ll be dicing like a pro in no time. If you prefer to save time and effort, feel free to purchase pre-chopped butternut squash, often available at major grocery stores and warehouse clubs like Costco.

Step-by-Step Guide to Preparing Butternut Squash:

1. Trim the Ends: Using a heavy, sharp chef’s knife, carefully slice off both the stem and bottom ends of the squash. This creates stable flat surfaces.
2. Peel the Skin: Stand the squash upright on one of its flat ends. With a sturdy vegetable peeler, remove the thick outer skin, working in downward strips from top to bottom. Be thorough, as the skin is quite fibrous.
3. Halve the Squash: Lay the peeled squash on its side. Carefully cut it in half lengthwise, starting from the wider, bulbous end and working towards the neck.
4. Scoop the Seeds: Use a spoon to scrape out the seeds and fibrous membranes from the hollow cavity of both halves. Discard these.
5. Dice into Cubes: Place the squash halves cut-side down on your cutting board. Slice them into long, even strips, then rotate and cut the strips crosswise into 1-inch (2.5 cm) cubes. Consistency in size helps ensure even cooking.

Safety Tip: Always use a stable cutting board and keep your fingers curled away from the knife blade. A damp paper towel placed under your cutting board can prevent it from slipping.

Effortless Butternut Squash Soup in Your Instant Pot

The Instant Pot truly shines with this recipe, transforming dense butternut squash into a velvety smooth soup in record time. This method significantly reduces cook time compared to traditional stovetop simmering, making it perfect for busy weeknights.

Making Butternut Squash Soup in the Instant Pot:

1. Sauté Aromatics: Begin by activating the “Sauté” function on your Instant Pot. Add a tablespoon or two of olive oil (or water for an oil-free option). Once heated, add diced sweet onion and minced garlic. Sauté for 2-3 minutes until fragrant and softened, stirring occasionally. This step builds a foundational layer of flavor for your soup. After sautéing, momentarily turn off the Instant Pot to prevent any potential “burn” messages during pressure cooking.
2. Build the Soup Base: Carefully add your cubed butternut squash and a pinch of ground nutmeg. Pour in 2-3 cups of vegetable broth, just enough to almost cover the squash cubes. It’s crucial not to overfill the pot. Before sealing, use a spatula to gently scrape any browned bits of onion and garlic from the bottom of the pot. This not only prevents a “burn” message but also incorporates those flavorful fond bits into your soup.
3. Pressure Cook: Secure the Instant Pot lid, ensuring the sealing valve is set to “Sealing.” Select the “Manual” or “Pressure Cook” button and set the cooking time to 10 minutes on high pressure. The Instant Pot will take a few minutes to come to pressure before the cooking timer begins.
4. Release Pressure and Blend: Once the cooking cycle is complete and the Instant Pot beeps, perform a careful Quick Release of the pressure. Always use a kitchen towel or oven mitt to protect your hand from the escaping steam. Once the float valve drops, you can safely open the lid.

Now, for the magic that transforms cooked squash into a smooth, luxurious soup. You have two excellent blending options:

• Immersion Blender: For ultimate convenience, use an immersion blender directly in the Instant Pot. Blend until the soup is completely smooth and free of lumps. This method minimizes cleanup.
• Regular Blender: If you don’t have an immersion blender, carefully transfer the cooked squash and broth mixture to a high-speed blender in batches. Do not overfill the blender, as hot liquids expand. Remove the center cap of the blender lid (if applicable) and cover the opening with a kitchen towel to allow steam to escape while blending. Blend until silky smooth, then return the soup to the pot.

After blending, taste the soup and adjust the seasoning with salt as needed. Butternut squash varies in sweetness and broth can vary in sodium, so always taste and adjust.

Achieving the Perfect Creaminess

To achieve that signature creamy texture without dairy, we rely on plant-based alternatives. Stir in 1 cup of rich Cashew Cream or full-fat coconut milk. Both options lend a luxurious mouthfeel, but cashew cream offers a neutral flavor profile that allows the butternut squash to truly shine. If you have a nut allergy or prefer a subtle tropical note, full-fat coconut milk is an excellent alternative. Ladle the warm soup into bowls and, if desired, swirl in a little extra cashew cream or coconut milk for an elegant finish.

Stovetop Method: A Classic Approach

No Instant Pot? No problem! You can absolutely achieve a delicious butternut squash soup using a large pot on your stovetop. It will take a little longer, but the results are equally satisfying.

Stovetop Instructions:

1. Sauté: In a large, heavy-bottomed pot or Dutch oven, heat 1-2 tablespoons of olive oil (or water) over medium heat. Add the diced onion and minced garlic and sauté for 3-5 minutes until softened and aromatic.
2. Simmer: Add the cubed butternut squash, nutmeg, and 2-3 cups of vegetable broth. Bring the mixture to a boil, then reduce the heat to low, cover the pot, and simmer for 20-30 minutes, or until the butternut squash is fork-tender. The cooking time will depend on the size of your squash cubes.
3. Blend and Finish: Once the squash is tender, remove the pot from the heat. Use an immersion blender to blend the soup directly in the pot until smooth and creamy. Alternatively, carefully transfer the soup in batches to a regular blender and process until smooth, taking precautions with hot liquids. Stir in the cashew cream or full-fat coconut milk and season with salt to taste. Serve warm.

Enhance Your Butternut Squash Soup

While this soup is perfect as is, you can always customize it to suit your taste preferences:

• Spice it Up: A pinch of cayenne pepper, a dash of curry powder, or a hint of ginger can add an exciting depth of flavor.
• Herbs: Fresh sage, rosemary, or thyme (like in the photos!) make excellent garnishes and add aromatic notes.
• Sweetness: If your squash isn’t quite sweet enough, a tiny drizzle of maple syrup can enhance its natural flavors.
• Toppings: Consider toasted pumpkin seeds (pepitas), croutons, a sprinkle of smoked paprika, or a swirl of plant-based sour cream for added texture and flavor.
