Celeriac Soup with Hazelnut Crumble

Featured in: Seasonal Bites

This comforting bowl combines roasted celeriac's natural sweetness with creamy potato for an ultra-smooth base. The magic happens in the oven first, where the celeriac develops deep, nutty flavors before being blended with vegetable broth and aromatics.

What truly elevates this dish is the hazelnut crumble—toasted until golden, tossed with butter and sea salt, then sprinkled generously on top. Each spoonful delivers velvety richness followed by satisfying crunch, creating a perfect balance of textures.

The preparation beautifully showcases celeriac's earthy profile while keeping the process straightforward. Roasting concentrates the vegetable's natural sugars, while a quick blend transforms it into restaurant-quality silkiness. Optional cream adds luxurious body, though the soup remains wonderfully satisfying without it.

Recipe Q&A

What does celeriac taste like?

Celeriac offers a subtle, earthy flavor with gentle celery notes and a mild sweetness. When roasted, these characteristics deepen and become more pronounced, developing a nutty quality that pairs beautifully with the hazelnut topping.

Can I make this soup ahead of time?

Absolutely. The base soup refrigerates beautifully for up to 3 days. Prepare through step 6, let cool completely, and store in an airtight container. Reheat gently over medium-low heat, adding a splash of broth or cream if needed. Toast and prepare the hazelnut crumble fresh before serving for optimal texture.

What can I substitute for hazelnuts?

Walnuts make an excellent alternative, offering similar earthy notes. Pecans work well too, bringing a slightly sweeter profile. For a nut-free option, try toasted pumpkin seeds or sunflower seeds—they'll still provide that essential crunchy contrast to the smooth soup.

Why roast the celeriac instead of boiling it?

Roasting concentrates celeriac's natural sugars and develops caramelized notes you simply can't achieve through boiling alone. The dry heat creates golden edges and deeper flavor, making the final soup noticeably more complex and satisfying. It's an extra step that makes a significant difference.

Is the cream necessary?

Not at all. The potato naturally thickens the soup, creating body without dairy. The cream simply adds extra richness. For a lighter version, skip it entirely or use a plant-based alternative. The soup remains velvety and satisfying either way.

How do I achieve the smoothest texture?

Ensure the vegetables are completely tender before blending—they should yield easily to a fork. An immersion blender works well, but a high-speed countertop blender produces the silkiest results. If using a countertop blender, work in batches and vent carefully to release steam. Blend for at least 2 minutes for ultra-smooth consistency.
