How to Make Butternut Squash Soup with Gruyere Croutons Recipe

Step 1: Sauté the Aromatics

Start by heating olive oil and butter in a large pot over medium heat. Toss in the chopped onions and cook them slowly until they turn soft and golden. This step is crucial because it unlocks the onions’ natural sweetness, setting a flavorful foundation for your soup’s depth.

Step 2: Build the Flavor Base

Add tomato paste, smoked paprika, and dried thyme to the pot. Cooking these spices for a couple of minutes releases their oils and aroma, giving the soup an inviting, warm scent that hints at the richness to come. Then stir in the cubed butternut squash, letting it mingle with the seasonings for several minutes.

Step 3: Add Garlic and Stock, Then Simmer

Grate the garlic in next to brighten the soup with its subtly sharp flavor. Pour in the vegetable stock—enough to mostly cover the squash—and bring everything to a boil. Lower the heat, cover the pot, and simmer until the squash is tender enough to mash easily. This slow cooking melds the flavors and softens the squash perfectly.

Step 4: Prepare Gruyere Croutons

While the soup simmers, preheat your oven to 350°F (175°C). Cube your baguette or bread slices and toss them lightly with olive oil on a baking sheet lined with parchment paper. Sprinkle generously with finely grated Gruyere cheese, then bake for about 15 minutes until the cheese bubbles and melts into glorious, golden croutons that add irresistible texture to your soup.

Step 5: Purée and Season the Soup

Once the squash is tender, turn off the heat and either use an immersion blender or transfer the soup in batches to a blender for a perfectly smooth purée. Stir in the maple syrup and salt, adjusting these to achieve a well-balanced sweetness and seasoning that elevates the soup’s natural character.

Step 6: Assemble and Serve

Ladle the creamy soup into bowls, then add a dollop of sour cream or crème fraîche if you like a creamy tang. Top with a handful of those golden Gruyere croutons and sprinkle fresh parsley over the top for a vibrant pop of color and freshness.

Garnishes

While the soup is delightful on its own, garnishes take it to another level. A swirl of sour cream or crème fraîche adds richness, while a sprinkle of chopped parsley lends freshness and a burst of green. You can also experiment with a few toasted pumpkin seeds or a dash of extra smoked paprika for a finishing wow factor.

Side Dishes

This soup pairs beautifully with simple sides that complement its flavors without overpowering them. A crisp green salad with a light vinaigrette, roasted root vegetables, or even a soft, buttery dinner roll can round out the meal perfectly, making it satisfying and balanced from start to finish.

Creative Ways to Present

For a charming touch, serve the soup in rustic bread bowls, which makes every spoonful extra cozy. Alternatively, layering a small spoonful of fresh herb-infused ricotta on top or swirling in some pumpkin seed oil can add visual appeal and subtle flavor nuances that make this Butternut Squash Soup with Gruyere Croutons Recipe feel extra special at your table.

Make Ahead and Storage

Storing Leftovers

Once cooled, store leftover soup in an airtight container in the refrigerator for up to two days. Keep your Gruyere croutons separate in an airtight bag to maintain their crispness so that when you are ready to enjoy your leftovers, every bite is just as delightful as the first.

Freezing

This soup freezes beautifully, making it an excellent choice for meal prep. Pour the cooled soup into freezer-safe containers and freeze for up to three months. Remember to freeze the croutons separately, as they don’t hold up well in the freezer but can be freshly baked before serving.

Reheating

Reheat your butternut squash soup gently over low to medium heat on the stovetop, stirring occasionally until evenly warmed. Avoid boiling as this can affect the texture and flavor. Add the croutons right before serving to keep them crisp and melty where the Gruyere shines.

FAQs

Can I use a different type of cheese for the croutons?

Absolutely! While Gruyere is traditional for its nutty, melting qualities, you can experiment with other cheeses like cheddar or fontina for a different twist. Just keep in mind that the cheese should melt well to create those gooey croutons.

Is there a way to make this soup vegan?

Yes, you can easily adapt this Butternut Squash Soup with Gruyere Croutons Recipe for a vegan diet by using vegetable stock, omitting the butter, and substituting the Gruyere cheese with a plant-based cheese alternative. Also, replace the sour cream with a dairy-free version or coconut cream for a creamy finish.

How do I peel and cube butternut squash safely?

Use a sturdy vegetable peeler to remove the skin, then cut off both ends of the squash to stabilize it. Slice it in half lengthwise, scoop out the seeds, and carefully cut into cubes. A sharp knife and steady hands make this easier and safer.

Can I make the soup spicier?

Definitely! You can add a pinch of cayenne pepper or a dash of chili flakes along with the smoked paprika to give the soup a little kick. Start with small amounts and adjust to your spice preference as you cook.

What’s the best way to serve the soup for a dinner party?

Serve the soup in elegant bowls with a garnish of sour cream and fresh parsley, accompanied by a platter of the Gruyere croutons on the side. Pair it with light, crisp white wine and a simple salad to impress your guests with both flavor and presentation.
