What You’ll Need for This Roasted Parsnip Soup with Thyme:

Ingredients for Roasted Parsnip Soup with Thyme including parsnips, onion, garlic, thyme, vegetable broth, olive oil, bay leaf, salt, pepper, and plant-based milk
  • 2 pounds parsnips (about 6 medium-sized), peeled and chopped 
  • 1 large onion, roughly chopped 
  • 3 cloves garlic, peeled 
  • 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme) 
  • 4 cups vegetable broth (low sodium preferred) 
  • 2 tablespoons olive oil 
  • 1 bay leaf 
  • Salt and pepper, to taste 
  • 1 cup unsweetened plant-based milk (like almond or oat, for creamy parsnip soup texture)

If you don’t have fresh thyme on hand, dried thyme works beautifully in this Roasted Parsnip Soup with Thyme, just use a bit less since dried herbs pack a stronger punch. Most of these ingredients are easy to find at your local grocery store or farmers’ market. Parsnips are often affordable, especially in fall and winter, which makes this soup wallet-friendly.

Quick prep tip: I find that roasting the parsnips and garlic together brings out the best flavor with minimal effort. You can chop your veggies ahead of time, store them in an airtight container, and be ready to roast whenever you want a batch of this Roasted Parsnip Soup with Thyme.

Don’t forget to keep your vegetable broth stocked in the freezer or fridge—it saves so much time when making this vegan roasted parsnip soup. I like to add an extra sprig of thyme while roasting for just a touch more aroma—it’s my little trick that makes this Roasted Parsnip Soup with Thyme extra wonderful.

How to Make This Roasted Parsnip Soup with Thyme:

  1. Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup. 
  2. Toss the peeled and chopped parsnips along with whole garlic cloves in olive oil and sprinkle with some fresh thyme leaves. Spread them out evenly on the sheet. Roast for about 25-30 minutes until they are tender and golden brown on the edges. Your kitchen will start to smell absolutely heavenly—a sign your Roasted Parsnip Soup with Thyme is on its way.
  3. While the parsnips roast, chop your onion roughly. In a large pot over medium heat, add a splash of olive oil and sauté the onion until soft and translucent, about 5-7 minutes. This is the step where a gentle hand makes all the difference with your Roasted Parsnip Soup with Thyme—be patient and let the onions develop that natural sweetness.
  4. Add the roasted parsnips and garlic to the pot with onions. Pour in the vegetable broth and throw in the bay leaf and a pinch of salt and pepper. Bring the mixture to a simmer and let it cook for 15 minutes to allow all those cozy flavors to blend together beautifully.
  5. Remove the bay leaf, then carefully blend the soup with an immersion blender until smooth and creamy. If you don’t have an immersion blender, transfer the soup in batches to a regular blender (just be cautious—hot liquid!). This part is where your creamy parsnip soup texture comes alive.
  6. Stir in the plant-based milk until fully incorporated and check for seasoning, adding more salt, pepper, or thyme if needed. From start to finish, this Roasted Parsnip Soup with Thyme takes about an hour, which is perfect for a comforting fall soup fix.
  7. Serve hot with a sprinkle of fresh thyme as a thyme garnish soup touch. While your Roasted Parsnip Soup with Thyme warms up your kitchen, take a moment to tidy up or enjoy a cup of tea—you deserve it.

If your soup looks perfectly smooth and tastes like it could warm any chilly day, you’re on track. If it’s a little thick, add broth a splash at a time until you reach your desired creaminess. Roasting is what sets this soup apart from your everyday creamy parsnip soup, giving it that lovely depth of flavor.

Serving Your Roasted Parsnip Soup with Thyme:

Serving Roasted Parsnip Soup with Thyme garnished with fresh thyme and crusty bread

This Roasted Parsnip Soup with Thyme really shines when served simply with a crusty bread or a fresh green salad. I love to pair mine with a warm whole-grain roll and a bit of vegan butter. It’s an easy combo that makes the comforting fall soup feel like a full meal.

For a thyme garnish soup flourish, I often add a small sprig of fresh thyme on top or a swirl of olive oil. It adds that little bit of extra charm without any fuss. If you’re hosting a casual gathering, this Roasted Parsnip Soup with Thyme impresses without stealing all your time in the kitchen.

Leftovers? No problem. This vegan roasted parsnip soup keeps well in the fridge for up to three days and actually tastes even better the next day. You can also freeze it in portions. When you want a splash of variety, stir in some sautéed mushrooms or top with roasted pumpkin seeds.

Seasonal note: during winter, I like to mix in a bit of roasted carrot or celery root to make a delicious roasted root vegetable soup twist with the same beloved thyme garnish soup style. Friends and family love how versatile and cozy this soup feels all through the colder months.

Common Questions About This Roasted Parsnip Soup with Thyme:

Can I make this Roasted Parsnip Soup with Thyme ahead of time?

Absolutely! It actually tastes even better the next day after the flavors have had time to meld. Just keep it in an airtight container in the fridge for up to three days or freeze in portions for longer storage.

What’s a good substitute for plant-based milk in this Roasted Parsnip Soup with Thyme?

I’ve used regular milk, coconut milk, and even cashew cream with great results. If you want to keep it vegan, almond or oat milk works beautifully and keeps that creamy parsnip soup texture.

Can I use dried thyme instead of fresh?

Yes! Use about a third of the amount of dried thyme since it’s more concentrated. It still adds that comforting fragrant note we love in this Roasted Parsnip Soup with Thyme.

How can I adjust this soup for smaller or larger batches?

This recipe scales really well. Just adjust your baking time slightly for roasting and keep an eye on the texture as you blend. More parsnips mean a thicker soup, so you might want extra broth or plant-based milk on hand.

Can I add other root vegetables to this soup?

For sure! Roasted carrots, sweet potatoes, or celery root all add nice layers of flavor. This gives you a lovely roasted root vegetable soup variation while keeping the thyme garnish soup feel.

How thick should my Roasted Parsnip Soup with Thyme be?

I prefer mine creamy but not too thick—think comforting fall soup you can sip from a bowl. You can thin it with broth or plant milk to suit your taste.

I don’t have a blender. Any ideas?

If you’re okay with a chunkier texture, you can mash the roasted parsnips with a potato masher. It’s not as silky but still delicious. Otherwise, a regular blender works fine—just blend in batches carefully.

If you love this Roasted Parsnip Soup with Thyme, you might also enjoy recipes like the roasted cauliflower curry soup from CakesByBelinda’s blog for a different spin on creamy roasted soups. And for something hearty and full of flavor, try the garlic butter beef bites with creamy mashed potatoes—perfect comfort food alongside this vegan roasted parsnip soup.
