Smooth, aromatic, and full of flavor — this Vietnamese Spiced Butternut Squash Bisque blends curry, lemongrass, and a little kick of serrano for a comforting Southeast Asian twist.

Vietnamese Spiced Butternut Squash Bisque: All About That Butternut Glow-Up
I came up with Vietnamese Spiced Butternut Squash Bisque inspired by Vietnamese cooking. I’m definitely not an expert in Vietnamese cuisine, but I did my research and wanted to bring together ingredients often used in their dishes to honor those flavors in my own way. The base builds layers of warmth from curry, lemongrass, coriander, cinnamon, cardamom, and a touch of serrano heat, all balanced by creamy butternut squash and coconut milk. It’s cozy, flavorful, and such a comforting bowl for fall. Top it however you like—it’s delicious as is or with a sprinkle of peanuts, cilantro, or a squeeze of lime.

Soup vs. Bisque: What’s the Difference?
A bisque is essentially a richer, creamier form of soup. Traditional French bisques were made with shellfish and thickened with cream, but today the term is used more loosely for any smooth, pureed soup with a luscious texture. The difference comes down to texture and body—a bisque is blended until silky and finished with something creamy (like coconut milk here), giving it that luxurious feel that sets it apart from a regular soup.

Ingredient Highlight: Lemongrass
Lemongrass is one of the key aromatics that gives Vietnamese dishes their signature brightness. It has a fresh, citrusy aroma that pairs beautifully with rich ingredients like coconut milk and squash, cutting through their sweetness with a hint of zest. If using fresh lemongrass, trim the stalk, remove the tough outer layers, and crush it to release its natural oils—it infuses a cleaner, more vibrant flavor than paste.

Madly Delicious Must-Know Tips and Questions
- Use full-fat coconut milk for the creamiest texture and richest flavor.
- Make it spicier. Add an extra slice or two of serrano, or a drizzle of chili oil before serving.
- Make it mild. Remove the seeds and membrane from the pepper, or swap in a small amount of red bell pepper for color without heat.
- Don’t skip blending. This is what gives the bisque that smooth, restaurant-style texture.
Can I make this ahead of time?
Yes! This bisque reheats beautifully. The flavors actually deepen after a day in the fridge, so it’s great for meal prep or easy lunches.
What can I serve it with?
Try it with crusty bread, jasmine rice, or even a side of crispy tofu for a more filling meal.
Let’s Dish: Did You Know?
The French influence in Vietnamese cuisine dates back to the colonial period, when Vietnam was part of French Indochina. Over the years, French techniques blended with local ingredients and traditions, creating something completely unique. Baguettes became the base for bánh mì, butter and pâté met fresh herbs and fish sauce, and strong coffee turned into the sweet, creamy cà phê sữa đá made with condensed milk. It’s that cross-cultural blend that gives Vietnamese food its signature balance of richness, freshness, and flavor.

- 1 tbsp fresh ginger, roughly chopped (about a 1½" piece)
- 1 tbsp lemongrass paste (or 1 stalk fresh lemongrass, trimmed and crushed)
- 1 tbsp curry powder
- 1½ tsp coriander
- 1 tsp tumeric
- ¾ tsp cinnamon
- ¾ tsp cardamom
- 1 tsp salt, adjust to taste
- ½ tsp black pepper, adjust to taste
- 4 cups low-sodium vegetable broth

- 1 (13.5 oz) can coconut milk
- 1-2 limes, juiced (start with 1 and adjust)
Optional Garnish
- Cilantro, chopped
- Unsalted peanuts, raw or roasted, chopped
- Lime wedges
- Serrano, thinly sliced
Instructions
- Prep the Squash: Peel and cube the butternut squash into roughly 1-2 inch pieces, removing the seeds with a spoon. Set aside.
- Sauté the Aromatics: In a large pot or Dutch oven, heat 2 tbsp coconut oil over medium heat. Add medium diced onion and sauté for about 5 minutes, until translucent and fragrant.
- Add Flavor Base: Stir in 2–3 cloves chopped garlic, 1 tbsp chopped ginger, and ½–1 diced serrano pepper. Add 1 tbsp lemongrass paste (or 1 crushed lemongrass stalk if using fresh). Cook for another 2 minutes, stirring frequently, until fragrant.
- Toast the Spices: Add 1 tbsp curry powder, 1½ tsp coriander, 1 tsp turmeric, ¾ tsp cinnamon, ¾ tsp cardamom, 1 tsp salt, and ½ tsp black pepper. Stir and cook for 1 minute to bloom the spices.
- Simmer the Squash: Add the cubed butternut squash and 4 cups vegetable broth. Bring to a boil, then reduce heat and simmer for about 20 minutes, or until the squash is tender.
- Remove Lemongrass & Blend: Discard the lemongrass stalk if using fresh. Remove the pot from heat and carefully blend the soup with an immersion blender until smooth, or transfer to a blender in batches, once it has cooled slightly.
- Add Creaminess & Season: Return the soup to low heat and stir in 1 can coconut milk, 1 tbsp soy sauce, and the juice of 1 lime. Taste and adjust with more salt, pepper, or lime juice as needed.
- Simmer & Serve: Let the soup simmer gently for about 10 minutes to allow the flavors to meld. Ladle into bowls and top with your desired garnishes.
