Imagine a dish that transforms humble root vegetables into a silky, nutty purée that rivals any rich, dairy-laden classic. This plant-based Vegetable Purée with Walnuts achieves that luscious texture without a drop of cream—thanks to a clever blend of celeriac, carrot, onion, and a splash of plant milk. The earthy sweetness of the vegetables is elevated by the toasty crunch of walnuts and a final drizzle of peppery olive oil. Perfect as a side dish or a light main, this recipe is a testament to how simple ingredients can create profound comfort. And with the right tools—like a powerful non-toxic immersion blender—you can achieve a restaurant-quality finish in minutes.
About This Velvety Vegetable Purée
This dish is a celebration of winter roots, particularly celeriac, which lends a subtle celery-like perfume and a creamy consistency when cooked and blended. Carrot adds natural sweetness, while onion provides a savory backbone. Instead of heavy cream, we use plant milk (oat, almond, or soy work beautifully) or vegetable broth, making this purée naturally dairy-free and vegan. The walnuts are dry-roasted to deepen their flavor, then roughly chopped for textural contrast. It’s a versatile base for roasted mushrooms, grilled tofu, or simply enjoyed on its own with crusty bread. For a truly seamless texture, a high-performance glass blender or a food processor for nut butter can also be used to achieve an ultra-smooth finish.
Ingredients
- 500 g celeriac (celery root)
- 1 carrot
- 1 onion
- 200 ml plant-based milk or vegetable broth
- 50 g walnuts
- 3 tbsp olive oil, plus extra for drizzling
- Salt, to taste
- Freshly ground black pepper, to taste
- Fresh spinach leaves, for garnish
Step-by-Step Method
- Sauté the vegetables: Peel and roughly chop the celeriac, carrot, and onion into even pieces. Heat the olive oil in a saucepan or Dutch oven over medium heat. Add the vegetables and cook, stirring occasionally, until they begin to soften and develop a golden color, about 8–10 minutes. For even browning, use a best oil sprayer to mist the pan lightly. Season with salt and pour in 100 ml of water. Cover and simmer for 10 minutes, until the vegetables are fork-tender.
- Blend to a smooth purée: Remove from heat. Use an immersion blender directly in the pot to purée the vegetables until completely smooth. If you prefer an even finer texture, transfer the mixture to a glass blender jar and blend on high for 30 seconds. Return to the saucepan.
- Finish with plant milk: In a small saucepan or microwave-safe container, gently heat the plant milk (or vegetable broth) until it just begins to simmer. Pour it into the purée and whisk or blend again to incorporate. Bring the mixture to a gentle simmer over low heat, stirring often. Adjust seasoning with salt and pepper. For a creamier consistency, use an air fryer? No, not relevant. Instead, consider using a microwave pressure cooker to quickly steam the vegetables before blending.
- Toast and garnish: While the purée simmers, place the walnuts in a dry skillet over medium heat. Toast, shaking the pan frequently, until fragrant and lightly browned, about 3–4 minutes. Remove from heat and roughly chop. To make chopping easier, you can pulse them in a food processor for nut butter set to a coarse chop. Divide the purée among bowls, top with walnuts, fresh spinach leaves, a generous crack of black pepper, and a drizzle of olive oil.
Tips for the Perfect Purée
- Use fresh celeriac: Look for roots that feel heavy and firm, with no soft spots. The fresher the celeriac, the sweeter the purée.
- Don’t skip toasting the walnuts: Dry-roasting releases essential oils and intensifies the nutty flavor, adding a crucial layer of complexity.
- Blend hot: Blending the vegetables while they’re still warm ensures a silky texture; cold vegetables can result in a gummy purée.
- Adjust consistency: Add more plant milk or broth if the purée is too thick. For a lighter version, replace half the milk with additional water. A under-counter ice maker is not relevant, but a good refrigerant leak detector ensures your fridge runs optimally to store leftovers.
- Season gradually: Salt the vegetables at the beginning to draw out moisture, but adjust final seasoning after blending, as the plant milk can change salt perception.
Delicious Variations
This purée is a blank canvas for creative twists. Swap the walnuts for pine nuts, hazelnuts, or even pepitas for a different crunch. For a spicy kick, add a pinch of smoked paprika or cayenne pepper with the milk. If you’re not dairy-free, use heavy cream or half-and-half for an even richer result. You can also fold in roasted garlic cloves or a handful of fresh herbs like parsley or thyme before blending. Serve the purée as a base for pan-seared scallops, poached eggs, or herb-roasted chicken. A garnish of toasted chocolate-covered raisins might be an unusual but delightful sweet-savory addition if you’re feeling adventurous.
Frequently Asked Questions
Can I make this purée ahead of time?
Yes, the purée can be prepared up to two days in advance. Store it in an airtight container in the refrigerator. Reheat gently on the stovetop with a splash of milk or broth to restore the creamy texture.
What is the best blender for this recipe?
An immersion blender works wonderfully for quick cleanup and direct blending in the pot. For an ultra-smooth texture, a high-speed glass blender is ideal.
Can I freeze vegetable purée?
Absolutely. Let the purée cool completely, then transfer to freezer-safe containers. It keeps well for up to three months. Thaw overnight in the refrigerator and reheat as above. Note that the texture may thin slightly upon thawing; simply whisk in a little cornstarch slurry if needed.
Is this recipe suitable for a nut-free diet?
To make it nut-free, skip the walnuts and replace them with toasted sunflower seeds or pumpkin seeds for a similar crunch. The purée itself contains no nuts if you use a nut-free plant milk like oat milk.
What can I use instead of celeriac?
If celeriac is unavailable, try substituting with an equal weight of parsnips or turnips. The flavor will be slightly different but still delicious. For a sweeter purée, use half celeriac and half potato.
How do I make this purée extra creamy without dairy?
Use full-fat coconut milk or oat milk (barista-style) for the richest vegan creaminess. Also, blending in a tablespoon of raw cashew butter or nutritional yeast can enhance the savory depth. A planetary mixer with a whisk attachment could be used to whip air into the finished purée, but it’s not necessary.
Can I use a food processor instead of a blender?
Yes, a food processor for nut butter can also process the vegetables into a smooth purée, though you may need to scrape down the sides frequently. A food processor is especially useful if you want to chop the walnuts as well.
What protein pairs best with this purée?
The earthy sweetness complements roasted poultry, grilled fish, or pan-seared tofu. For a vegan bowl, top with marinated chickpeas and a sprinkle of hemp seeds.
