Roasted Beet and Ginger Soup

Jump to Recipe

I’ll be honest, beet soup looked like a hard sell the first time I made it. Deep purple, slightly sweet, not what you’d call a crowd-pleaser on paper.

But roasting changes everything. The beets get caramelized edges, their sweetness firms up and mellows, and when you add a knob of fresh ginger, the whole thing shifts. It’s earthy and warm with a little heat at the back of your throat.

This is a blended soup, so the texture is smooth and almost creamy without any cream at all, much like a roasted garlic cauliflower soup gets its body from the vegetables alone. A spoonful of plain yogurt on top and a few toasted seeds are all you need.

It reheats well, keeps for four days in the fridge, and the color alone is worth making it once.

Why You’ll Love This Recipe

• Roasting beets first builds deep, caramelized flavor
• Naturally smooth and creamy with no cream needed
• Strong make-ahead soup that keeps four days refrigerated
• Bright color and bold ginger warmth in every bowl

Ingredient Notes

• Fresh beets: Use medium beets, about 600 g total. Pre-cooked vacuum-packed beets work in a pinch but skip the roasting step and you lose that caramelized depth.
• Fresh ginger: A 2-inch piece gives good heat without overwhelming the beets. Ground ginger works as a sub, use about 1 tsp, but the flavor is flatter.
• Vegetable broth: Low-sodium broth gives you more control over seasoning. Chicken broth works if you’re not keeping this vegetarian.
• Red onion: Red onion keeps the color clean in the final soup. Yellow onion is fine but can push the color slightly brown at the edges.
• Plain yogurt: Swirled on top for a creamy, tangy contrast. Coconut cream is the best dairy-free swap and it pairs well with ginger.
• Olive oil: Used for both roasting the beets and sauteing the aromatics. Any neutral oil like avocado or sunflower works too.

Ingredients

  

For roasting

• 600 g medium fresh beets, scrubbed about 4 medium beets
• 1 tbsp olive oil
• 1/2 tsp salt

For the soup

• 1 tbsp olive oil
• 1 medium red onion, roughly chopped about 150 g
• 3 garlic cloves, sliced
• 40 g fresh ginger, peeled and grated about a 2-inch piece, divided
• 900 ml low-sodium vegetable broth plus more to thin if needed
• 3/4 tsp salt adjust to taste
• 1/4 tsp black pepper
• 1 tbsp fresh lemon juice

To serve

• 4 tbsp plain whole-milk yogurt one spoonful per bowl
• 2 tbsp toasted pumpkin seeds
• small handful fresh dill or chives optional

Method

 

Roast the beets

1. Heat the oven to 200 C / 390 F.
2. Drizzle each beet with a little olive oil, season with salt, and wrap each one individually in foil.
3. Place on a rimmed sheet pan and roast for 50 to 60 minutes, until a knife slides in with no resistance.
4. Remove from the oven and let cool for 10 minutes, then peel by rubbing the skins off with a paper towel. Chop into rough chunks.

Build the soup base

1. Heat 1 tbsp olive oil in a large saucepan over medium heat.
2. Add the red onion and cook for 5 to 6 minutes, stirring occasionally, until softened and translucent.
3. Add the garlic and half of the grated ginger. Cook for 1 minute until fragrant.
4. Add the roasted beet chunks and pour in the vegetable broth. Season with salt and black pepper.
5. Bring to a simmer and cook for 10 minutes to let the flavors come together.

Blend and finish

1. Remove the pan from the heat. Add the remaining raw ginger and the lemon juice.
2. Blend until completely smooth using an immersion blender directly in the pan, or transfer in batches to a high-powered blender. Leave the lid vent open when blending hot liquid.
3. Return to the pan if needed and reheat gently over low heat. Taste and adjust salt, pepper, or lemon juice.
4. Ladle into bowls and top each with a swirl of yogurt, a pinch of toasted pumpkin seeds, and fresh dill or chives if using. Serve hot.

Notes

Add the second half of the ginger raw into the blender rather than cooking it all to keep a fresh, bright heat in the finished soup. If the soup tastes flat after blending, lemon juice fixes it faster than more salt.

Tips for Success

• Wrap beets tightly in foil individually so they steam while roasting and become tender all the way through.
• Peel beets while still warm by rubbing with a paper towel, the skin slides off without staining your hands badly.
• Add ginger in two stages, half with the onion and half raw into the blender, for both cooked warmth and the kind of bright fresh ginger heat you’d find in wellness shots.
• Blend in batches if using a standard blender and leave the lid vent open to release steam safely.
• Taste for acidity before serving and add a squeeze of lemon juice if the soup tastes flat or overly sweet.

Variations

• Stir in 400 ml coconut milk instead of extra broth for a creamy, dairy-free beet coconut ginger soup.
• Add a roasted carrot or two with the beets for a slightly sweeter, more golden-toned version.
• Finish with a drizzle of chili oil and pickled ginger slices for a sharper, spicier bowl.

Storage and Reheating

Store cooled soup in an airtight container in the fridge for up to 4 days. The flavor actually improves on day two as the ginger settles into the broth.

To reheat, warm gently in a saucepan over medium-low heat, stirring occasionally, until steaming. Add a splash of broth or water if it has thickened too much.

This soup freezes well for up to 3 months. Freeze flat in zip-lock bags or in portioned containers. Thaw overnight in the fridge before reheating. Add the yogurt swirl fresh after reheating, not before freezing.

Serving Suggestions

Serve in wide shallow bowls with a generous swirl of plain yogurt, a pinch of toasted pumpkin seeds, and a little fresh dill or chives on top. The yogurt cuts the earthiness and makes the color pop.

A thick slice of sourdough or a warm seeded roll alongside is all you need for a full lunch. The bread is good for scooping up the last of the soup.

For a dinner starter, pour the soup into smaller cups and skip the toppings except for a tiny dot of yogurt and a crack of black pepper. It works well before roasted chicken or a simple grain salad.

FAQ

Why does my roasted beet and ginger soup taste too sweet?

Beets are naturally high in sugar and roasting intensifies that. Add a squeeze of fresh lemon juice or a small splash of apple cider vinegar to balance the sweetness. A little extra salt also helps bring the savory notes forward.

Can I use ground ginger instead of fresh ginger in this soup?

You can, but fresh ginger gives a brighter, sharper heat that ground ginger can’t quite replicate. If substituting, use about 1 teaspoon of ground ginger added when you saute the onion.

How do I know when the beets are done roasting?

Pierce the largest beet with a paring knife or skewer. It should slide in with almost no resistance, like a cooked potato. At 200 C, medium beets usually take 50 to 60 minutes wrapped in foil.

Can I freeze roasted beet soup with the yogurt already stirred in?

No, yogurt separates when frozen and the texture turns grainy after reheating. Freeze the blended soup base on its own and add a fresh spoonful of yogurt after you reheat each portion.

Is roasted beet and ginger soup gluten-free?

Yes, this soup is naturally gluten-free as written. Just double-check your vegetable broth label, some commercial broths contain gluten-based thickeners or flavorings.

What pairs well with roasted beet and ginger soup as a side?

Crusty sourdough or rye bread is the classic pairing and holds up well for dipping. A simple arugula salad with lemon dressing or a soft goat cheese crostini also works well alongside it.
