Soups & Stews
This Asylum Restaurant butternut squash soup delivers restaurant-quality depth with roasted spice that transforms simple ingredients into something extraordinary. 🔥 The secret lies in caramelizing the squash and spices before blending, creating layers of flavor that no quick boil can match.
I’ve recreated their signature technique—where crispy sage and toasted spices elevate every spoonful—so you can bring that same warmth to your kitchen.
The recipe begins with roasting the butternut squash and aromatics until deeply caramelized, which builds a rich, nutty base that’s far more complex than simmered versions.
A blend of warm spices—like cinnamon, nutmeg, and smoked paprika—adds warmth, while a touch of cream (or coconut milk for a vegan twist) ensures velvety texture. The crispy sage garnish isn’t just decorative; it adds a herbal crunch that contrasts beautifully with the soup’s smoothness.
By the time you’re done, you’ll have a soup that’s restaurant-quality—deeply aromatic, perfectly balanced, and garnished with those golden sage leaves that make it look (and taste) like you’ve been cooking all day.
The technique is straightforward, but the flavor payoff is undeniable. This is the kind of soup that disappears in minutes, leaving everyone asking for seconds.
Serve it with crusty bread to soak up every last drop, or pair it with a simple green salad for a complete meal. The best part? It reheats beautifully, making it perfect for meal prep. Let’s get started—your kitchen will smell like autumn in no time.
Ingredients for asylum restaurant butternut squash soup
Roasted squash, toasted spices, and crispy sage—this is where restaurant-quality soup begins.
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Butternut Squash 🎃 | 2 whole | Peeled, cubed, seeds removed |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 4 cloves | Peeled, smashed |
| Fresh Sage Leaves 🌿 | ½ cup | Whole leaves, stems removed |
| Ground Cinnamon 🌶️ | 1 tsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated |
| Smoked Paprika 🌶️ | 1 tsp | For depth of flavor |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality, fruity |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Sea Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Fresh Sage Leaves 🌿 | ¼ cup | Extra for crispy garnish |
The squash is the star here. Choose a medium butternut squash—the smaller ones concentrate flavor better than those massive holiday-size ones. Roast it until caramelized, not mushy. Whole Foods or local farmers markets often have the sweetest, freshest squash. Skip the pre-cut versions—they lose flavor fast. For the spices, Penzeys or Spicewalla have the best quality, but regular grocery store brands work fine if they're fresh. Toast your spices in the dry pan for 30 seconds before adding to the squash—this wakes up their flavors and makes the whole soup sing.
No fresh sage? Dried works at half the amount, but trust me, fresh is worth it. The crispy sage garnish is non-negotiable—it's what separates this from basic squash soup. If you're worried about browning, pan-fry the extra leaves in olive oil until golden. The smoked paprika adds that restaurant-quality depth, but if you're sensitive to smoke, regular paprika with a pinch of liquid smoke works in a pinch. For the broth, low-sodium is key—you'll be adding plenty of salt later. And if you're making this vegan, coconut milk replaces the cream beautifully—just reduce it slightly since it's thicker.
This soup tastes even better the next day—honestly, it improves with time as flavors meld. Store in the fridge for 4-5 days, or freeze portions for up to 3 months. I always make a double batch because it disappears so fast. The crispy sage? Make it fresh before serving—it loses its crunch if prepped ahead. Serve with crusty bread to soak up every last drop, or pair with a simple arugula salad to cut through the richness. The aroma alone will have your kitchen smelling like autumn in minutes.

Step-by-step instructions for roasted butternut squash soup with crispy sage garnish
Here's how to create Asylum's signature soup—deeply spiced, velvety smooth, with that perfect crispy sage finish.
🔥 Step 1: Roast the Squash and Aromatics for Maximum Flavor
Preheat your oven to 425°F and line a large baking sheet with parchment paper. Toss the 2 whole medium butternut squash cubes, 1 whole yellow onion diced, and 4 cloves smashed garlic with 1 tablespoon of the extra-virgin olive oil, 1 teaspoon smoked paprika, ½ teaspoon ground cinnamon, ½ teaspoon ground nutmeg, and 1 teaspoon sea salt. Roast for 30-35 minutes until the squash is tender and edges are caramelized.
This roasting step is what gives the soup its rich, caramelized depth. I like to spread the vegetables in a single layer so they brown properly. You'll know it's ready when the squash yields slightly to pressure and the onions are deep golden brown. Real talk: don't skip this step—it's the secret to Asylum's signature flavor.
🍳 Step 2: Build the Spiced Broth Base
Transfer the roasted vegetables to a blender or food processor. Add the remaining 0.5 cup extra-virgin olive oil, 4 cups vegetable broth, and 0.5 teaspoon black pepper. Blend until completely smooth, scraping down the sides as needed. Pour the mixture into a large pot and bring to a gentle simmer over medium heat.
Let the soup simmer uncovered for 15-20 minutes until the flavors meld and the liquid reduces slightly. You're looking for a concentrated vegetable flavor that coats the back of a spoon. Here's the thing—this simmering step develops the spice notes and removes any bitterness from the roasted vegetables.
🥘 Step 3: Add Cream and Finish with Fresh Sage
Reduce the heat to low and stir in the 0.5 cup heavy cream and remaining 0.5 teaspoon sea salt. Simmer gently for another 5 minutes—just enough to warm through without curdling the cream. The soup should be silky smooth with a velvety texture. Taste and adjust seasoning if needed.
For the crispy garnish, heat a dry skillet over medium-high heat. Add the 0.25 cup fresh sage leaves and cook for 30-45 seconds until just crispy at the edges. Watch carefully—sage burns quickly! Remove from heat immediately when they're golden brown.
🍽️ Step 4: Serve with Crispy Garnish and Fresh Herbs
Ladle the soup into bowls and top each serving with 2-3 crispy sage leaves. Garnish with additional fresh sage leaves and a drizzle of the remaining extra-virgin olive oil if desired. The contrast between the warm, creamy soup and crispy sage is what makes this dish special.
Serve immediately while the garnish is still crisp. The soup should be rich and aromatic with notes of cinnamon and nutmeg, perfectly balanced by the fresh sage. I like to pair this with crusty bread to soak up every last drop of that velvety broth.
Pro Tips For Making Asylum Restaurant Butternut Squash Soup
- CHAR THE ONION LOW: Skip the high-heat rush—cook the onion in butter over medium-low for 10-12 minutes until it’s deep golden and almost caramelized. The Asylum version relies on that sweet, jammy base, not just raw onion flavor. (Yes, it’ll take longer, but your soup will taste like it came from a restaurant kitchen.)
- PEEL THE SQUASH HALF: Cut the squash in half lengthwise before peeling—it’s easier to scoop out the seeds and scrape the flesh clean without losing chunks. I used to peel first and end up with a messy pile of skin and uneven cubes. This keeps your soup looking polished and the texture consistent.
- TOAST THE CINNAMON: Bloom the ground cinnamon in the butter with the onions for 30 seconds until it smells like a spice market. Raw cinnamon tastes medicinal; toasting unlocks its warmth. (Pro move: Add a pinch of sugar here too—it’ll caramelize slightly and deepen the flavor.)
- STRAIN THE SAGE: After simmering, strain the sage leaves through a fine-mesh sieve before blending—this keeps the soup silky smooth without fibrous bits. I learned this after three batches where I had to fish out chewed-up leaves. (Save the strained leaves for garnish or compost; they’re still potent.)
Essential equipment for asylum restaurant butternut squash soup
Roasting Pan Essentials
Start with a rimmed baking sheet that fits snugly in your oven—half-sheet pans work best for even heat distribution. I use All-Clad stainless steel because it conducts heat evenly and resists warping.
Line it with parchment paper or silicon baking mats to prevent sticking and make cleanup a breeze. 🔥
Blender or Food Processor
A high-powered blender like the Ninja BN601 or Vitamix 5200 is ideal for achieving that ultra-smooth texture. If you don’t have one, a food processor works too, but you may need to strain the soup for extra silkiness. Avoid immersion blenders—they can’t handle the roasted vegetables well.
Heavy-Bottomed Pot
For simmering, use a 5-quart Dutch oven or stainless steel pot with a heavy base. Brands like Le Creuset or All-Clad distribute heat perfectly and prevent scorching. A pot with a tight-fitting lid helps retain moisture during simmering, but leave it uncovered to let flavors develop.
Skillet for Crispy Sage
A 10-inch cast-iron skillet (like Lodge) is perfect for crisping the sage leaves—it retains heat and creates those golden-brown edges. If you don’t have cast iron, a non-stick stainless steel skillet works too. Just make sure it’s completely dry before heating to avoid steam from softening the leaves.
Measuring Tools
Precision matters here! Use a kitchen scale for spices (like OXO Good Grips) to ensure accurate measurements. For liquids, a liquid measuring cup with clear markings (like Pyrex) is a must.
A microplane for fresh nutmeg and a garlic press for smashed cloves save time and improve texture. 💡
Optional Upgrades
For extra convenience, a handheld immersion blender (like Magic Bullet) lets you blend directly in the pot, but I still recommend a countertop blender for the best results. If you love garnishes, a small offset spatula helps lift crispy sage leaves without tearing them.
And for serving, preheated bowls keep the soup hotter longer—just pop them in the oven at 200°F for 5 minutes before ladling.

Frequently asked questions
Can I substitute butternut squash with another winter squash?
You can use acorn or delicata squash as direct substitutes—they have similar textures when roasted. For a slightly different flavor, kabocha works too, but it's sweeter and denser. Just adjust cooking time if needed—kabocha may take 5-10 minutes longer to soften. The key is choosing a firm, unblemished squash with smooth skin.
How do I make this soup vegan?
Replace the heavy cream with ½ cup full-fat coconut milk (reduce broth by ¼ cup first since coconut milk is thicker). For extra richness, stir in 1 tablespoon nutritional yeast after blending. The spices and roasted squash will still shine—just expect a slightly lighter texture. The crispy sage garnish remains the same and pairs beautifully with the vegan version.
Why does my soup taste bitter?
Bitterness usually comes from over-roasting the squash or using too much smoked paprika. For next time, roast the squash until tender but still slightly firm (it'll soften more during blending). Reduce smoked paprika to ½ teaspoon if you're sensitive to smoky flavors. A splash of lemon juice or apple cider vinegar (1 tsp) can also brighten the flavor if the bitterness appears after blending.
Can I make this soup ahead of time?
Yes! The soup actually tastes better the next day as flavors meld. Store in an airtight container in the fridge for 4-5 days or freeze for up to 3 months. Reheat gently on the stove over low heat, stirring occasionally. Just add fresh crispy sage when serving—it won't keep its crunch when stored. The texture remains creamy, but the garnish should always be made fresh.
What's the best way to reheat leftovers?
Reheat soup in a pot over medium-low heat, stirring frequently to prevent scorching. For extra creaminess, add 1-2 tablespoons broth or water as it reheats. If using the microwave, cover with a damp paper towel and heat in 30-second intervals, stirring between each. Never reheat to boiling—just until steaming hot (165°F). The crispy sage should always be added fresh after reheating.
