Ingredient Notes

Spicy chili powder, savory veggie broth, and fragrant garlic help bring out the flavors in this parsnip potato soup. Scroll to the bottom of the post for exact ingredient amounts.

• Butter – I prefer unsalted butter. Margarine works too.
• Olive oil – Feel free to use corn, canola, or vegetable oil.
• Parsnips – Make sure they’re peeled.
• Potatoes – 2 cups baby potatoes are a great swap.
• Carrots – You can use 1 cup baby carrots instead.
• Yellow onion – White onions are fine as well.
• Garlic – Fresh garlic and garlic paste are best for this.
• Fresh herbs – You need parsley and basil.
• Salt and pepper – Go for kosher salt and freshly-cracked black pepper.
• Bay leaf – Feel free to leave it out.
• Vegetable broth – Low-sodium versions are best.
• 2% milk – You can also use half-and-half or heavy cream.
• Chili powder – Cayenne pepper and red pepper flakes are good substitutes.

What Are Parsnips? What Do They Taste Like?

Parsnips are a pale-looking, fall and winter root veggie with a white to beige color. They’re long, thin, and pointy on one end. Parsnips are basically carrots’ close cousin. They’re also related to parsley. In terms of flavor, they have a sweet and slightly spicy licorice-like taste that’ll remind you of radishes. They also have a subtly nutty taste to them.

Tips and Variation Ideas

You can make this creamy parsnip potato soup even more comforting with some cream of chicken, cheese, and leftover veggies.

• Use leftovers. Swap the raw potatoes for leftover Air Fryer Potatoes or Grilled Potatoes in Foil. You can also use my Garlic Butter Roasted Carrots and Air Fryer Carrots. Don’t add them to the pot until the rest of the veggies are cooked through.
• Make it cheesy. Mix 4 oz cream cheese into the pot 5 minutes before blending the soup for added creaminess.
• Add protein. Shred my Instant Pot Turkey Breast or Roasted Chicken. Top the soup with it for a heartier bite.
• More soup. Instead of using milk for the recipe, add your favorite canned cream of chicken or cream of mushroom soup.
• Use the right pot. While stainless steel pots are great, it’s extremely easy for things to stick and burn. Use a non-stick pot or Dutch oven for making this soup to prevent any messes.
• Add toppings. A sprinkle of crispy croutons, salted pistachios, or crumbled bacon can add wonderful texture and flavor.

What Goes With Potato Parsnip Soup?

Hearty parsnip potato soup is great with your favorite steak, chicken, and pork dinners. I love it with my Juicy Pork Loin Roast, Steak au Poivre, or Classic Baked Chicken. For side ideas, stick to non-starchy recipes like my Asparagus Frittata and Shaved Brussels Sprouts Salad.

How to Store and Reheat Extras

This rich parsnip potato soup is great for prepping your weeknight dinners in advance.

• Fridge: Place it in an airtight container for up to 4 days. Discard immediately if it tastes sour.
• Freezer: Pour it into freezer bags or containers in serving-size portions. Freeze for up to 3 months and thaw overnight in the fridge. If it separates, use the immersion blender to process it again for 20-30 seconds until smooth.
• To reheat it: Microwave it for 30 seconds, stir, and microwave again until warm. For larger portions use a pot over medium-high heat for 8-10 minutes.
