Step‑by‑Step Instructions for Golden Butternut Dashi Soup
Step 1: Prep the Butternut Squash
Start by preheating your oven to 400°F (200°C). Carefully peel the large butternut squash, then cut it in half and scoop out the seeds. Chop the squash into even cubes and spread them on a baking sheet. Drizzle with olive oil and sprinkle with salt; roast for about 25–30 minutes until tender and lightly caramelized, giving them a golden hue.
Step 2: Make the Soup Base
Once the roasted butternut squash is cool enough to handle, add it to a blender with the pack of dashi and soy milk. Blend until you reach a velvety smooth consistency, which should take about 1-2 minutes. Pour the mixture into a pot over medium heat; simmer for 5–7 minutes, stirring occasionally, and season with salt and pepper to enhance the flavor of your Golden Butternut Dashi Soup.
Step 3: Prepare the Tempura
In a deep skillet or pot, heat vegetable oil to 350°F (175°C). While the oil is heating, dip the asparagus stalks into the tempura batter, ensuring they are well-coated. When the oil is hot, carefully fry the battered vegetables in batches for about 3–4 minutes until they are golden brown and crispy. Remove them with a slotted spoon and place on paper towels to drain excess oil.
Step 4: Serve the Soup
Ladle the warm Golden Butternut Dashi Soup into bowls, filling them generously. Top each bowl with the crispy tempura vegetables for a striking contrast. For an added touch of flavor and visual appeal, sprinkle sesame seeds and chopped chives on top. Finally, drizzle a bit of chili oil over the soup to elevate the experience with a spicy kick.

Make Ahead Options
These Golden Butternut Dashi Soup preparations are a lifesaver for busy home cooks! You can make the soup base up to 24 hours in advance by blending the roasted squash with soy milk and dashi, then storing it in an airtight container in the refrigerator. Additionally, pre-cut and wash your vegetables for tempura, keeping them fresh in the fridge for up to 3 days. On the day of serving, simply reheat the soup on the stovetop until warm, and fry the tempura just before you’re ready to serve for that crispy texture. This approach allows you to enjoy a delicious, homemade meal with minimal effort, making it perfect for a cozy weeknight dinner.

Golden Butternut Dashi Soup Recipe FAQs
How do I choose the right butternut squash?
Absolutely! Look for a butternut squash that feels heavy for its size and has a smooth, firm skin. Avoid any with dark spots all over or soft spots, as they indicate overripeness. The best squashes will have a deep golden-orange color, which suggests sweetness and flavor.
What’s the best way to store leftover soup?
Leftover Golden Butternut Dashi Soup can be stored in an airtight container in the fridge for up to 3 days. Be sure to let it cool completely before sealing it up. When reheating, do so gently over medium heat on the stove, adding a splash of soy milk if needed to restore its creamy texture.
Can I freeze Golden Butternut Dashi Soup?
Absolutely! You can freeze the soup in a freezer-safe container for up to 2 months. Just let it cool before storing. To thaw, move it to the fridge overnight, and then reheat gently on the stove. Stir well to combine, as some separation may occur during freezing.
What can I do if my tempura turns out soggy?
If your tempura isn’t crisp, it’s often due to oil that isn’t hot enough. Make sure your oil reaches about 350°F (175°C) for optimum frying. Try a small drop of batter; if it doesn’t sizzle immediately, wait a bit longer before frying. Also, frying in smaller batches helps maintain a higher oil temperature.
Can I adjust the spice level in the soup?
Very much so! If you prefer less heat, start by adding just a small drizzle of chili oil after serving. Taste first, as you can always add more if you want it spicier. You might also consider using sriracha in place of chili oil for a different flavor profile.
Is this soup suitable for a vegetarian or vegan diet?
Definitely! This Golden Butternut Dashi Soup is not only vegetarian but can easily be made vegan by ensuring the soy milk is free from any animal products. For those with nut allergies, simply swap the soy milk for oat milk, and you’re all set!
