Roasted Butternut Squash & Apple Soup | Sage Brown Butter

There’s nothing quite like the embrace of a warm bowl of soup when the leaves start to turn and the air grows crisp. Fall nights call for comfort, and for us, that means simmering something truly special on the stove. This Creamy Roasted Butternut Squash and Apple Soup with Sage Brown Butter is more than just a meal; it’s a hug in a bowl, a celebration of autumn’s bounty, and surprisingly simple to bring together for a delightful family dinner or a cozy evening in.

Ingredients & Substitutions

Gathering your ingredients is the first step to creating this soul-warming soup. We’ve broken down each item, its purpose, and handy alternatives.

• Butternut Squash (about 2-3 lbs, 1 medium): This is the creamy, sweet base of our soup. Its natural sweetness deepens beautifully when roasted.
  • Substitution: You can easily swap for an equal amount of sweet potato or even kabocha squash for a slightly different flavor profile.
• Apples (2 medium, sweet-tart varieties like Honeycrisp or Fuji): Apples add a lovely, subtle tartness that balances the richness of the squash and brings out autumn flavors.
  • Substitution: Pears (Bosc or Anjou) would offer a similar sweetness and texture, or you could use a Granny Smith if you prefer a sharper tang.
• Yellow Onion (1 medium): A foundational aromatic that adds depth and savory notes.
  • Substitution: White onion works just as well, or you could use two shallots for a milder onion flavor.
• Garlic (4-5 cloves): Roasting garlic mellows its intensity and adds a wonderful, sweet aroma to the soup.
  • Substitution: Garlic powder can be used in a pinch (about 1 teaspoon), but fresh roasted garlic truly elevates the flavor.
• Olive Oil (2 tablespoons): For roasting the vegetables until tender and slightly caramelized.
  • Substitution: Any neutral oil like avocado oil or even melted coconut oil would be suitable.
• Vegetable Broth (4-6 cups): The liquid base for our soup, adding essential savory flavor.
  • Substitution: Chicken broth can be used if you don’t need the soup to be vegetarian. For a richer flavor, you could even use half broth and half water.
• Heavy Cream (1/2 cup): This is what gives our soup its luxurious, silky texture.
  • Substitution: For a dairy-free option, full-fat coconut milk (canned) works wonderfully and adds a subtle tropical note. Half-and-half or evaporated milk are also lighter alternatives.
• Fresh Sage Leaves (6-8 large leaves, plus more for garnish): The star of our brown butter, infusing it with an earthy, aromatic warmth that screams fall.
  • Substitution: Fresh thyme sprigs could offer a different but equally lovely herbaceous note. Dried sage (1/2 teaspoon) can be used, but fresh is highly recommended here.
• Unsalted Butter (4 tablespoons): For creating that delectable sage brown butter topping.
  • Substitution: Vegan butter alternatives can be used if preferred, though achieving the same nutty brown butter flavor might be slightly different.
• Maple Syrup (1-2 tablespoons, optional): A touch of maple enhances the natural sweetness of the squash and apple.
  • Substitution: A teaspoon of brown sugar or a drizzle of honey could also be used.
• Salt and Black Pepper (to taste): Essential for seasoning and bringing all the flavors into harmony.

Pro Tips

Making a truly comforting soup is all about those little details. Here are some pointers to help you achieve perfection every time:

• Roast for Flavor: Don’t rush the roasting process. Allowing your squash, apples, and onions to get slightly caramelized at the edges is key. This develops a deeper, sweeter, and more complex flavor profile than simply boiling them.
• Season in Layers: Add salt and pepper not just at the end, but also lightly when you’re roasting the vegetables, and again when the soup is simmering. This builds a more balanced flavor throughout.
• Blending Safety First: When blending hot soup, never fill your blender to the top. Work in batches, filling the blender only about halfway. Remove the center cap of the lid (the one for adding liquids) and cover the opening with a kitchen towel to allow steam to escape and prevent pressure buildup.
• Adjust Consistency: If your soup is too thick, add more warm vegetable broth a little at a time until it reaches your desired consistency. If it’s too thin, let it simmer uncovered for a bit longer to reduce, or try stirring in a tablespoon of cornstarch mixed with a little cold water.
• The Brown Butter Magic: Keep a close eye on your butter when browning it. It can go from perfectly nutty to burnt very quickly. Swirl the pan constantly and remove it from the heat as soon as you see those lovely amber flecks and smell a toasty aroma.
• Taste, Taste, Taste: This is the golden rule of cooking! Before serving, always taste your soup. Does it need more salt? A pinch of pepper? A little more maple syrup to brighten the sweetness? Adjust to your preference.
• Peeling Butternut Squash: For easier peeling, you can microwave the whole squash for 2-3 minutes before attempting to peel. The skin will soften slightly, making it much easier to manage.

What to Serve With It

This roasted butternut squash and apple soup is wonderfully satisfying on its own, but a few accompaniments can make it an even more special meal:

• Crusty Bread or Dinner Rolls: Perfect for dipping and soaking up every last drop of the creamy goodness.
• Toasted Pepitas (Pumpkin Seeds): Adds a delightful crunch and nutty flavor as a garnish.
• Garlic and Herb Croutons: Homemade or store-bought, they provide texture and an extra layer of savory flavor.
• Simple Green Salad: A light, crisp salad with a vinaigrette dressing offers a refreshing contrast to the rich soup.
• Grilled Cheese Sandwiches: The ultimate comfort food pairing, especially with a sharp cheddar.
• A Crisp White Wine: A Chardonnay or Pinot Grigio would complement the earthy flavors beautifully.

How to Store & Reheat

This soup makes fantastic leftovers, perfect for a quick, cozy meal on a busy day.

Storage: Allow the soup to cool completely before transferring it to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days.

Reheating:

• Stovetop: This is our preferred method for the best results. Gently reheat the soup over medium-low heat, stirring occasionally, until it’s warmed through. If it’s too thick, add a splash of vegetable broth or water to reach your desired consistency.
• Microwave: For individual servings, heat in a microwave-safe bowl in 1-minute intervals, stirring between each, until hot.

Freshness Tips: If you find the soup has thickened too much in the fridge, a little extra broth or even a touch of cream will bring it back to life. Give it a taste and adjust seasonings if needed after reheating.

Can You Freeze It?

Absolutely! This soup freezes exceptionally well, making it perfect for meal prep during those busy fall weeks.

How to Freeze:

1. Ensure the soup is completely cooled.
2. Portion the soup into freezer-safe containers, leaving a little headspace at the top for expansion. You can also freeze individual servings in Ziploc bags laid flat (once solid, stack them to save space).
3. Label with the date. It will keep well in the freezer for up to 3 months.

How to Thaw & Reheat:

1. Thawing: The best way to thaw is overnight in the refrigerator. If you’re in a hurry, you can gently thaw it in a pot over low heat on the stove, stirring frequently, or use the defrost setting on your microwave.
2. Reheating: Once thawed, reheat gently on the stovetop over medium-low heat, stirring often. You may find the texture has thickened slightly. Simply whisk in a little extra vegetable broth or a splash of cream until it reaches your desired consistency.

The texture and flavor hold up wonderfully after freezing and thawing, providing that same cozy comfort whenever you need it.

FAQ

Q: Can I make this soup ahead of time?
A: Absolutely! This soup is a fantastic make-ahead option. You can prepare it entirely up to the point of adding the sage brown butter. Store it in an airtight container in the refrigerator for up to 3-4 days. When ready to serve, gently reheat on the stovetop and then prepare the fresh sage brown butter just before serving for the best aroma and flavor.

Q: How can I make this soup dairy-free or vegan?
A: Making this soup dairy-free and vegan is simple! For the heavy cream, substitute with full-fat canned coconut milk (it adds a lovely richness without a strong coconut flavor, especially when balanced with the squash and apple). For the butter in the sage brown butter, use a good quality plant-based butter alternative. Follow all other instructions as written, and you’ll have a wonderfully satisfying vegan soup.

Q: My soup is too thick/thin after blending. What should I do?
A: If your soup is too thick, gradually stir in more warm vegetable broth (or even a little water) until it reaches your desired consistency. For a soup that’s too thin, let it simmer uncovered over low heat for an additional 10-15 minutes, stirring occasionally, to allow some of the liquid to evaporate and thicken slightly. Avoid boiling vigorously, which can affect the creamy texture.

Q: Can I use dried sage instead of fresh for the brown butter?
A: While fresh sage provides the best flavor and texture for the crispy leaves in the brown butter, you can use dried sage in a pinch. If using dried, reduce the amount to about 1/2 teaspoon, as its flavor is more concentrated. Add it to the butter as it browns, but be mindful that it won’t crisp up the same way fresh leaves do, and will contribute more of an infused flavor rather than a garnish.

Q: What’s the best way to get the butternut squash peeled and cubed easily?
A: Butternut squash can be tricky! A great tip is to pierce the squash several times with a fork and microwave it for 2-3 minutes. This softens the skin slightly, making it much easier to peel with a vegetable peeler. Then, carefully slice off the ends, cut the squash in half lengthwise, scoop out the seeds, and cut it into manageable strips before cubing.
