Most people walk past celeriac at the grocery store like it owes them money. Knobby, weird-looking, zero Instagram appeal. Big mistake.

This Celeriac & Apple Soup with Hazelnut Oil is one of those recipes that punches way above its weight. Creamy without any cream. Sweet without being dessert. And that hazelnut oil finish? It's the kind of detail that makes people ask if you went to culinary school.

You didn't. You just showed up on a Tuesday. That's enough.

Key Takeaways

• 🥣 5 core ingredients — celeriac, apple, onion, broth, hazelnut oil
• ⏱️ Ready in under 45 minutes from start to finish
• 🌱 Naturally dairy-free and vegan — no swaps needed
• 🔪 No fancy equipment — just a pot and a blender
• 💡 Hazelnut oil is the move — don't skip it, it transforms the whole bowl

Why Celeriac Deserves a Spot in Your Kitchen

Straight up — celeriac is underrated. It's the root of the celery plant, and it tastes like celery and parsnip had a quieter, nuttier kid.

Nutritional wins:

• High in Vitamin K and Vitamin C
• Good source of fiber and phosphorus
• Lower in carbs than potato — solid for anyone watching that

It blends silky smooth. It holds up to bold flavors. And it costs less than most trendy vegetables right now.

Do the work to find it. Worth the grind.

How to Make Celeriac & Apple Soup with Hazelnut Oil

Step 1: Prep Your Veg (10 min)

Peel the celeriac. Yes, it's ugly. Get in there anyway.

Cube it roughly — about 2cm pieces. Peel and core the apples, cut into chunks. Chop the onion. Smash the garlic.

No need to be precise. It's all getting blended.

Step 2: Build the Base (10 min)

Heat olive oil in a large pot over medium heat.

Add onion and garlic. Cook 4–5 minutes until soft and translucent. Don't rush this. Soft onions = sweeter soup.

Add celeriac and apple. Stir everything together. Let it sit for 2 minutes — you want a little color on the celeriac.

Step 3: Simmer Down (20 min)

Pour in the broth. Bring to a boil, then drop to a simmer.

Cover and cook 18–20 minutes until celeriac is completely tender. Poke it with a fork — if it falls apart, you're good.

Season with salt and white pepper now.

Step 4: Blend It Smooth

Use an immersion blender directly in the pot. Or transfer in batches to a standing blender.

Blend until completely smooth. No chunks. This soup earns its silky texture — don't cut corners here.

Taste. Adjust salt. Done.

Step 5: The Hazelnut Oil Finish

Ladle into bowls.

Drizzle hazelnut oil over the top. Don't stir it in — let it sit on the surface. That's the move.

Add toasted hazelnuts and a few thin apple slices if you want to make it look like you tried.

Consistent beats perfect. But this looks pretty good either way.

Troubleshooting + Pro Tips

Soup too thick? Add a splash of warm broth or water. Blend again briefly.

Not sweet enough? Use a sweeter apple variety — Fuji or Gala works.

Can't find hazelnut oil? Walnut oil is a solid backup. Toasted sesame at a pinch — different vibe, still works.

Want more depth? Add a small parsnip with the celeriac. Builds complexity without extra effort.

Storage & Meal Prep

This soup is built different for meal prep.

• 🧊 Fridge: Keeps 4–5 days in an airtight container
• ❄️ Freezer: Up to 3 months — freeze before adding hazelnut oil
• 🔥 Reheat: Low heat on the stovetop, stir occasionally. Add hazelnut oil fresh each time.

Batch it on Sunday. Show up for yourself all week.

Celeriac & Apple Soup with Hazelnut Oil is the kind of recipe that makes a Tuesday feel like you've got it together. Five real ingredients. One pot. Under 45 minutes.

Your next steps:
