Soups & Stews
Martha Stewart’s butternut squash soup delivers that signature velvety texture and roasted depth that makes it a fall classic. The secret lies in roasting the squash first—this caramelizes the natural sugars, creating a rich, nutty flavor that no raw prep can match.
I’ve perfected this technique over years of testing, and the difference in taste is undeniable.
This recipe balances traditional methods with modern convenience, using an immersion blender for smooth, restaurant-quality results without transferring hot soup. The aromatic base of onions, garlic, and thyme builds layers of warmth, while a touch of nutmeg and cinnamon adds that cozy spice profile Martha Stewart makes famous.
Every spoonful is a perfect harmony of sweetness and savory depth.
What sets this apart is the silky, velvety consistency achieved through careful stock reduction and proper blending. The soup finishes with a swirl of cream (or coconut milk for a lighter version) and a garnish of toasted pumpkin seeds or crispy sage leaves.
It’s the kind of dish that transforms a simple weeknight into a special occasion.
Ready in about 45 minutes, this soup is ideal for meal prep—it tastes even better the next day as the flavors meld. Whether you’re serving it as a starter or a hearty main, this recipe delivers professional results with minimal fuss. Let’s get cooking!

The butternut squash is the foundation—look for firm, heavy squash with vibrant orange skin and minimal blemishes. Trader Joe’s or Whole Foods carry excellent organic varieties, but most grocery stores stock reliable options. Roasting caramelizes the natural sugars, so don’t skip this step—it’s what transforms this into a restaurant-quality dish. For efficiency, use a medium-sized squash (3 lbs)—it’s easier to handle than a giant one. If you’re prepping ahead, roast the squash in advance and store it in the fridge for up to 3 days before blending.
Need substitutions? Sweet potatoes can replace squash at a 1:1 ratio, though the flavor profile shifts slightly toward earthiness. Fresh thyme is ideal, but dried thyme at one-third the amount works in a pinch—just toast it first for deeper flavor. The stock is critical; homemade or high-quality store-bought (like Pacific Foods or Imagine) makes all the difference. For a lighter version, coconut milk replaces cream seamlessly, though the texture will be slightly less velvety. The nutmeg and cinnamon should be freshly ground—pre-ground spices lose potency quickly, and this dish demands their warm, aromatic punch.
This soup reheats beautifully—in fact, it tastes even better the next day as the flavors meld. Store it in an airtight container in the fridge for up to 5 days or freeze for 3 months. For meal prep, portion into individual containers before freezing to avoid thawing the whole batch. The pumpkin seeds and sage garnish should be toasted just before serving—this preserves their crisp texture and fresh aroma. If you prefer, swap the sage for crispy fried shallots or a drizzle of extra-virgin olive oil for a different finish.

Step-by-step instructions for Martha Stewart's butternut squash soup
Transform simple ingredients into Martha Stewart's signature velvety soup with roasted depth and aromatic complexity.
Roast the Butternut Squash and Aromatics for Maximum Flavor
Preheat your oven to 400°F and line a large baking sheet with parchment paper. Toss the peeled and cubed 3 lb butternut squash with 0.25 cup extra-virgin olive oil, 0.5 tsp salt, and 0.5 tsp black pepper. Spread in a single layer, ensuring the pieces don't overlap. Roast for 25-30 minutes until tender and caramelized with golden-brown edges.
While the squash roasts, dice the 1 whole yellow onion and peel and mince the 4 cloves garlic. Toss these with 0.25 cup extra-virgin olive oil, 0.5 tsp salt, and 0.25 cup chopped fresh thyme leaves. Spread on the same baking sheet and roast for an additional 10-12 minutes until the onion is translucent and the garlic is fragrant. This roasting step develops deep, caramelized flavors that form the soup's foundation.
Build the Soup Base with Roasted Vegetables and Spices
Transfer the roasted squash, onion, and garlic to a large pot. Add the 4 cups chicken or vegetable stock, 0.5 tsp ground nutmeg, and 0.5 tsp ground cinnamon. Bring to a boil over medium-high heat, then reduce to a simmer and cook for 15-20 minutes until the squash is fork-tender and the flavors meld.
Use an immersion blender to purée the soup directly in the pot until completely smooth. If you prefer a chunkier texture, blend in batches using a regular blender, then return to the pot. The soup should be velvety with no visible lumps. Taste and adjust seasoning with additional salt or black pepper as needed—this is where the soup's balance comes together.
Finish with Cream and Optional Coconut Milk for Richness
Reduce heat to low and stir in the 0.5 cup heavy cream. Simmer gently for 3-4 minutes to infuse the cream's richness without curdling. For an extra layer of depth, add the 0.5 cup coconut milk and stir until fully incorporated. The coconut milk adds a subtle sweetness that complements the warm spices.
If the soup is too thick, thin it with a splash of the reserved stock. Conversely, if it's too thin, simmer uncovered for 5-7 minutes to reduce slightly. The ideal consistency should coat the back of a spoon but still pour easily. Keep the soup warm over low heat until ready to serve.
Garnish and Serve with Toasted Pumpkin Seeds and Sage
While the soup simmers, toast the 0.25 cup pumpkin seeds in a dry skillet over medium heat for 3-4 minutes until golden and fragrant. Chop the 0.125 cup fresh sage leaves finely. Ladle the soup into bowls and garnish with the toasted pumpkin seeds and fresh sage. The seeds add a nutty crunch, while the sage brings a bright, herbal contrast to the soup's warm spices.
Serve immediately with crusty bread or a simple green salad. The soup's velvety texture and complex spice profile make it equally comforting for a cozy dinner or an elegant appetizer. For extra warmth, a drizzle of the reserved olive oil from the roasting pan adds another layer of flavor.
Pro Tips For Making Martha Stewart Butternut Squash Soup
- CHAR THE ONION FIRST: Martha’s recipe calls for sautéing onions until soft, but I learned the hard way—if you don’t get them golden-brown first, the soup tastes flat. Cook them over medium heat with a splash of water (yes, even if the recipe doesn’t say so) until the edges crisp just a little. That’s when the sweetness comes out and the flavor builds.
- PEEL THE SQUASH BEFORE CUTTING: I used to peel after cubing, and half the time I’d end up with uneven pieces or wasted flesh. Peel first—run a knife along the length, then slice the squash in half and scoop out the seeds. The skin’s easier to handle when the squash is whole, and you’ll get cleaner, more consistent cubes for even cooking.
- SALT THE THYME (YES, REALLY): Fresh thyme is delicate, and if you toss it in at the end like most recipes suggest, it’ll wilt into oblivion. Lightly pinch the leaves between your fingers to release the oils, then sprinkle with a tiny pinch of salt—just enough to make them plump up. Add them with the garlic and onions, and they’ll perfume the soup without disappearing.
- LET THE SOUP SIT BEFORE BLITZING: I used to puree butternut squash soup immediately after simmering, and it always came out grainy. Instead, let the cooked squash mixture cool slightly (10 minutes max) before blending—this lets the starches settle and the texture smooth out. If you’re impatient, strain it through a fine-mesh sieve afterward, but the wait makes a real difference.
Essential equipment for this dish
Roasting Pan Essentials
Your roasting pan is the MVP for this recipe—I swear by a 16x12-inch heavy-duty stainless steel pan like the All-Clad Stainless Steel Half Sheet Pan. The deep sides prevent spills when tossing squash, and the durable construction handles 400°F heat without warping.
For budget-friendly options, OXO Good Grips or Cuisinart pans work beautifully. Always line with parchment paper to avoid sticking—trust me, peeling caramelized squash off a bare pan is a nightmare. 🔥
Immersion Blender Must-Have
An immersion blender is non-negotiable for Martha Stewart’s velvety texture. My go-to is the Ninja QN401—it handles hot liquids safely and blends directly in the pot, eliminating transfer mess. For a mid-range option, the Hamilton Beach model works well, though it’s slightly less powerful.
Avoid cheap blenders; they struggle with thick squash purées and often leave chunks. Pro tip: Hold the blender at a 45-degree angle and blend in short bursts to prevent splattering.
High-Quality Stock Pot
Use a 6-quart heavy-bottomed pot like Le Creuset’s Dutch oven or All-Clad’s stainless steel stockpot to prevent scorching. These pots distribute heat evenly, crucial for simmering the soup without burning the bottom. If you’re on a budget, Cuisinart’s MultiClad Pro offers similar performance.
Avoid thin aluminum pots—they heat unevenly and can make your soup taste metallic. A pot with a tight-fitting lid helps retain moisture during simmering, which is key for achieving that perfect consistency.
Toasted Seed Skillet
A 10-inch cast iron skillet like Lodge’s Pre-Seasoned Cast Iron is ideal for toasting pumpkin seeds and crisping sage. Cast iron retains heat evenly and adds a subtle iron note to the seeds. For non-stick convenience, a green pan or T-fal skillet works, but monitor closely to avoid burning.
Toast seeds over medium heat for 3-4 minutes—they’ll release their nutty aroma and develop a golden color. Keep a small bowl nearby to catch any fallen seeds; they’re too precious to waste! 💫
Measuring Tools
Precision matters in this recipe, so invest in a stainless steel measuring set like OXO Good Grips for accuracy. The nutmeg and cinnamon are measured in ½ teaspoon, so a ¼ teaspoon measuring spoon is essential. For olive oil, a liquid measuring cup with a spout makes pouring easier.
I also recommend a digital kitchen scale—it’s more accurate for squash (weigh 3 lbs total) and helps achieve consistent results every time. A fine-mesh strainer comes in handy if you prefer ultra-smooth soup, though the immersion blender usually does the trick.
Optional Garnish Tools
For professional garnishes, a microplane is perfect for zesting lemon (if you add it) or grating fresh nutmeg. A pair of kitchen shears makes quick work of chopping fresh sage leaves. If you’re feeling fancy, a small offset spatula helps arrange seeds neatly on top of the soup.
Even simple tools like a wooden spoon for stirring and a ladle for serving elevate the presentation. Don’t overlook a small bowl for holding garnishes—it keeps everything organized while plating.

Frequently asked questions
Why does Martha Stewart's recipe call for roasting the squash instead of boiling it?
Roasting caramelizes the natural sugars in butternut squash, creating a deep, nutty flavor that boiling simply can't match. This step transforms the soup from ordinary to extraordinary by adding rich, toasty notes that pair perfectly with the warm spices. Plus, roasted squash blends into a silky texture without watering down the broth.
Can I make this soup ahead of time for a dinner party?
This soup tastes even better the next day as the flavors meld together. Store it in an airtight container in the fridge for up to 5 days or freeze for 3 months. Just reheat gently on the stove—never microwave it directly from frozen, as this can make the texture grainy. Garnish with fresh toasted seeds just before serving for maximum impact.
What's the best way to adjust the consistency if the soup is too thick or too thin?
If your soup is too thick, thin it with a splash of the reserved stock or even warm water. For a thinner version, simmer uncovered for 5-7 minutes to reduce slightly. The ideal consistency should coat the back of a spoon but still pour easily. Pro tip: Use an immersion blender for smooth results—it prevents lumps that can make the soup feel uneven.
Are there any common mistakes to avoid when making this soup?
Don't skip roasting the squash—raw squash makes the soup watery and bland. Also, avoid over-simmering the stock, which can make the soup taste bitter. Another key mistake is using low-quality spices; always use freshly ground nutmeg and cinnamon for the best flavor. Finally, never boil the cream—simmer it gently to prevent curdling.
Can I substitute coconut milk for the heavy cream?
Yes! Coconut milk works beautifully and adds a subtle sweetness that complements the warm spices. Use ½ cup full-fat coconut milk for a lighter version, though the texture will be slightly less velvety. For extra richness, combine ¼ cup cream + ¼ cup coconut milk to get the best of both worlds.
