Author Notes

From Sarah Britton's "Naturally Nourished" cookbook: "The process for this soup is incredibly easy: all the ingredients are placed on a rimmed baking sheet, and the oven does the work. There isn’t even a pot to wash when the meal’s over. You can use this procedure with any veggies, plus onions and garlic. Just add everything to a blender directly from the oven, pour in some hot vegetable broth, and dinner is served. Bam!"

What You'll Need
  • 1 small head of garlic
  • 1/2 teaspoon coconut oil or ghee
  • 2 pounds (1kg) parsnips
  • 3 medium yellow onions
  • 6 cups (1.5L) vegetable broth or water
  • 1 1/2 cups (250g) (about one 15.5-oz. can) white beans, such as cannellini, great northern, or navy, drained and rinsed
  • 1 to 2 teaspoons fine sea salt (use 1 teaspoon if using broth; 2 teaspoons if using water)
  • 1 tablespoon cold-pressed olive oil, plus more for serving
  • 1 tablespoon freshly squeezed lemon juice
  • Freshly ground black pepper, for serving
  • Parsley leaves, for serving (optional)
  1. Preheat the oven to 400° F (200° C). Slice off the stem of the garlic bulb and the portion just below the stem, revealing the open cloves. Spread the coconut oil on top, wrap the bulb tightly in aluminum foil, and set it on a rimmed baking sheet. Roast for 15 minutes.
  2. While the garlic is roasting, peel and roughly cut the parsnips into similarly sized chunks to ensure even roasting. Chop the onions. After the garlic has roasted for 15 minutes, add the parsnips and onions to the baking sheet. Roast until tender, about 30 minutes.
  3. Add the roasted parsnips and onions to a blender. Remove the foil from the garlic and squeeze the bulb from the bottom to extract the cloves into the blender. Add the broth, beans, salt, olive oil, and lemon juice, and blend on the highest setting until the soup is smooth and creamy. Transfer the soup to a stockpot and heat until steaming, if necessary.
  4. Serve hot with a drizzle of olive oil and some black pepper and parsley, if using.

This is delicious! The garlic head I had was a pretty good size, but that made for a lovely flavor. I followed the recipe measurements, but there is no way all the ingredients would fit in the blender. I did it in batches, which also helped for a smooth texture.

This soup was the tipping point for me to buy a Bamix Immersion blender! My tabletop blender was a hassle, and my immersion blender was ‘meh’. I’m making the soup again tonight!

Highly satisfying balance of savory and sweet: One sheet pan lined with parchment made for easy clean up; I roasted the veg w coconut oil and it worked very well w the parsnip; Veg were lightly caramelized; after reseasoning (important), I finished with white pepper, and garnished with nutmeg. Company could not get enough!
[Note: I love nutmeg with parsnip, but don't roast the veg with it — it will smell like....Listerine.]

Loved this soup. I added about a half teaspoon of dijon mustard to it and it was terrific. I did let the parsnips and onions caramelize a bit when I roasted them.

This was amazing! I substituted low sodium chicken stock for the vegetable stock and it’s soooooo delish. I also added an extra squeeze of lemon, because I can’t help myself (I live for 🍋)

I love parsnips, but this soup was really a disappointment...very bland and tasted like hospital food. Parsnips aren’t cheap either, so to have bought them only to make something that was barely edible was annoying.

A bit bland to my tastes. When reheating it I added a bunch of Penzeys "Singapore Seasoning" and some Sambal Oelek. I will make it again with less onion to kick the parsnip flavor up a notch.

I love parsnips and this sounds delicious and easy. Can’t wait to try it.
