Salt & pepper	To taste	Season as you go

Ingredient Notes & Substitutions

• Butternut squash: You can use pre-cut squash to save prep time. Frozen squash works too, no need to thaw.
• Apple: Adds a gentle fruitiness that balances the savory elements. For extra depth, use a tart-sweet variety like Honeycrisp.
• Broth: Swap in bone broth or chicken broth if you’re not vegetarian. Want extra flavor? Add a splash of apple cider or a bay leaf.
• Creaminess: The coconut milk is optional but gives a silky finish. For a nut-free, non-vegan version, use half-and-half or heavy cream instead.
• Spices: Try adding cinnamon, ginger, or smoked paprika for variation.

Step‑by‑Step Instructions

This recipe couldn’t be easier — just a few simple steps, minimal cleanup, and you’ll have a rich, comforting soup by dinner.

Step 1: Add Everything to the Slow Cooker

Place the cubed butternut squash, sliced carrots, chopped apple, diced onion, and minced garlic into your crockpot. Pour in the vegetable broth, then sprinkle in thyme, nutmeg, salt, and pepper.

Tip: Stir gently to combine, but don’t worry about perfect distribution — it will all blend together later.

Step 2: Cook Low and Slow

Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the vegetables are fork-tender.

Slow Cooker Tip: Avoid lifting the lid during cooking — it releases heat and slows everything down.

Step 3: Blend Until Smooth

Once the veggies are very soft, use an immersion blender to puree the soup directly in the crockpot until it’s smooth and silky.

No immersion blender? Let the soup cool slightly, then transfer it to a blender in batches, blending on low to avoid splattering. Return to the slow cooker afterward.

Step 4: Stir in the Coconut Milk (Optional)

For added creaminess, stir in ½ cup of coconut milk (or heavy cream if preferred). This adds a subtle richness and smooth finish, but it’s completely optional.

Step 5: Taste and Adjust

Taste the soup and adjust the seasoning. Add a pinch more salt, pepper, or nutmeg if needed. A splash of lemon juice or apple cider vinegar can also help brighten the flavor if it tastes too sweet.

Step 6: Serve and Garnish

Ladle the soup into bowls and top with optional garnishes such as:

• Fresh thyme or parsley
• A swirl of cream or coconut milk
• Roasted pumpkin seeds or croutons
• Crispy sage leaves for an elegant touch

Serve hot with crusty bread or a light salad on the side.

Tips, Variations & Serving Ideas

This soup is as flexible as it is flavorful. Whether you want to adjust the texture, spice it up, or turn it into a full meal, these tips and variations will help you make it your own.

Adjust the Texture to Your Preference

• For a silky-smooth soup: Blend thoroughly with an immersion blender until completely smooth.
• For a rustic feel: Blend only partially, or leave some chunks of squash and carrot for texture.
• Extra creamy version: Stir in more coconut milk, heavy cream, or even a dollop of Greek yogurt before serving.

Flavor Boosts & Add-Ins

Give your soup more personality with these creative twists:

• Spicy: Add a pinch of cayenne pepper or a swirl of sriracha for heat.
• Smoky: Stir in a dash of smoked paprika or use fire-roasted carrots or tomatoes.
• Sweet: A drizzle of maple syrup or a splash of apple cider enhances the natural sweetness.
• Earthy: Add ground ginger, curry powder, or cinnamon for a warm, complex flavor.
• Bright: Finish with a squeeze of lemon or splash of apple cider vinegar to balance sweetness.

Serving Suggestion

This butternut squash soup makes a great light main or a cozy starter. Try it with:

• Crusty Bread: A slice of sourdough or garlic bread for dipping
• Salads: Pair with arugula, kale, or apple walnut salad
• Protein Boost: Top with roasted chickpeas, white beans, or crispy tofu
• Garnishes: Add crunch with pumpkin seeds, croutons, or a swirl of coconut cream
• Fall Vibes: Garnish with crispy sage or toasted pecans for a seasonal touch

Storage & Reheating Tips

One of the best things about this slow cooker butternut squash soup is how well it stores and reheats — making it perfect for meal prep, make-ahead dinners, or freezing for a future cozy night in.

How to Store Leftovers

Let the soup cool to room temperature before storing. Transfer to airtight containers and refrigerate for up to 3–4 days.

• Use glass storage containers if possible — they help preserve freshness and make reheating easier.
• Label your containers with the date so you know when to enjoy them by.
• Stir the soup before serving leftovers to redistribute flavors and maintain the creamy texture.

How to Freeze Butternut Squash Soup

This soup freezes beautifully, but with one important tip:
Hold off on adding the coconut milk or cream before freezing. For best texture, stir it in fresh after reheating.

To freeze:

1. Let the soup cool completely.
2. Divide into individual portions using freezer-safe containers or silicone freezer cubes for easy grab-and-go meals.
3. Leave 1 inch of space at the top to allow for expansion.
4. Label with the date and contents.
5. Store flat if using bags — it saves freezer space and speeds up thawing.

It will keep well in the freezer for up to 3 months.

How to Reheat Butternut Squash Soup

On the stovetop:

Pour the thawed or refrigerated soup into a saucepan. Warm over low to medium heat, stirring occasionally until heated through.
Add a splash of broth, water, or coconut milk to thin it out if the soup has thickened.

In the microwave:
Transfer a portion to a microwave-safe bowl. Cover loosely and heat in 1-minute intervals, stirring in between, until hot.
Add liquid as needed to loosen the texture.

Bonus Tips

• Batch reheat only what you plan to eat. Repeated reheating can affect flavor and texture.
• Don’t boil after adding coconut milk or cream — gentle warming keeps the soup silky.
• Garnish after reheating for the best flavor and appearance.

Pair your soup with a hearty vegetarian main like this easy gratin de courgettes et riz for a complete and satisfying fall dinner.
