Parsnips are like the long-forgotten cousin of carrots. Perhaps you just pass them by, not really sure what to do with them – well, I hope to change that.

I love how food and our senses can evoke long-ago memories – it’s something that never ceases to amaze me. My mom used to bread and shallow-fry parsnips for me as a kid and I loved them so much! My memory of them is so strong that I can almost taste them as I write this.

The sweet earthiness that is different from any other root vegetable, parsnips make regular appearances in my fall and winter cooking. Whether they’re combined with potatoes to make the ultimate mashed potatoes or roasted with other roots alongside a whole chicken, I never tire of them.

They add an unexpected pop of flavor that is just perfect.

Let’s get into it!

Why I love this recipe:


  • BUDGET FRIENDLY – This is a very inexpensive side dish and only has seven ingredients, most of which you probably have in your pantry.
  • EASY & DELICIOUS SIDE DISH – These roasted parsnips could not be any easier to make – mix up the honey mustard sauce and roast them – easy peasy!
  • GREAT FOR THE HOLIDAYS – Around the holidays, we’re always looking for side dishes that are easy and a little bit different – this one fits the bill!

Ingredient Notes & Substitutions

The ingredients to make these roasted parsnips are easy to find and readily available at any grocery store.

Here are a few ingredient notes:

Parsnips: A parsnip is a light, cream-colored root vegetable from the carrot and parsley family and looks just like a carrot. It’s a naturally sweet vegetable, similar to a carrot, but the sweetness is more earthy in flavor. Use medium parsnips that are firm and look fresh without dried-out ends.

Dijon mustard: Use Dijon mustard for its sharpness, which lends a nice counterpoint to the sweetness of the parsnips and honey. Maille is the brand that I use and is my favorite among all of the brands of Dijon, but if you don’t have Dijon mustard, you can double down on the whole grain mustard as a substitute.

Whole grain mustard: Slightly more subtle than Dijon, whole grain mustard also brings a sharpness in flavor, but also the texture from the mustard seeds. Maille is my favorite and what I use, but if you don’t have whole-grain mustard, you can substitute Dijon or even a high-quality honey mustard.

Honey: Honey provides a little sweetness, but also has the effect of rounding out the sharpness of the mustard. You can substitute brown sugar or maple syrup if you don’t have honey.

Apple cider vinegar: Some acidity rounds out the flavor of the honey mustard sauce. You can substitute it with white wine vinegar or white balsamic vinegar.

Fresh thyme: Fresh thyme pairs nicely with mustard and also provides a nice pop of green to the finished dish. Substitute with fresh rosemary or parsley if you don’t have thyme.

Garlic: Use one clove of fresh garlic and grate it on a microplane, if you can, as it will emulsify into the sauce more easily and not burn when roasting.

Let’s Make Simple Honey and Mustard Roasted Parnsips Together: STEP BY STEP

Be sure to check out the full recipe details and ingredient list in the recipe card below.

Steps 3 & 4:

Third, using a vegetable peeler, peel the parsnips and discard the peels.

Next, cut the parsnips in half, crosswise, so that you have a thicker end and a thinner end.

Steps 5 & 6:

To cut the parsnips into ‘french fry’ shapes, take the thinner end and cut it in half, lengthwise, and then cut each half again lengthwise.

For the thicker end, cut them into quarters, lengthwise, and then standing each quarter upright, remove the core by cutting it from top to bottom.

Steps 7 & 8:

Finally, place the parsnips onto a sheet pan and toss them with the honey mustard sauce, making sure each one is coated and that they are spread out into a single layer.

Drizzle them with the remaining tablespoon of olive oil and roast them in a preheated oven for about 25 mintues.

Natalie’s Expert Tips

  • Cut all of the parsnips the same size, to the best of your ability, to prevent some being overcooked or undercooked.
  • If your parsnips are large, remove the core of the thick end of the parsnip, so that you don’t have any of the woody texture. See visual instructions above, or the recipe card below, for how to do this.
  • If you want your parsnips even more caramelized, turn your oven to broil, raise your oven rack, and put the parsnips under the broiler for a few minutes.

Serving Suggestions


Storage & Reheating

STORAGE:
Store the parsnips in an airtight container in the refrigerator for up to 4 days.

REHEATING:
To reheat in the oven, place everything in an oven-proof pan or dish with a splash of water and cover with aluminum foil. Place in a 375-degree oven until warmed through. Remove the foil for last 5 minutes, so the parsnips can crisp back up. On the stovetop, place everything into a sauté pan with a splash of water or cream and heat over medium-low heat until warmed through. And finally, you can also reheat everything in the microwave in 30 second intervals until they are warmed through.

FREEZING:
These parsnips freeze well in an airtight container for up to 6 months. Thaw in the refrigerator overnight before reheating.


Frequently Asked Questions for these Honey Mustard Parsnips

Yes, you certainly can. All air fryers seem to cook differently, but I would start with 10 minutes at 390 degrees F and adjust from there accordingly. Also, for best results, keep them in a single layer.

Yes, just substitute brown sugar or maple syrup for the honey.

Although they are best enjoyed right after they are made, they can be made beforehand. I suggest undercooking them slightly so they don’t become overcooked when reheating them.

As with any root vegetable, the only way to know if they are done is to pierce them with the tip of a knife. If the knife meets no resistance, they are done.

Carrots are the other root vegetables that would work well to add to the parsnips, as they will require the same cooking time. Be sure to cut them the same way and the same size.

Ingredients
  

  • 1 1/2 lbs medium parsnips
  • 2 tsp Dijon mustard
  • 2 tsp whole grain mustard
  • 3 tbsp honey
  • 1 tbsp apple cider vinegar
  • 1 garlic clove (grated)
  • 4 tbsp olive oil (divided)
  • 4 thyme sprigs
  • 1 1/2 tsp kosher salt
  • 1/2 tsp black pepper

Instructions
 

  • Preheat the oven to 400 degrees Fahrenheit.
  • Prepare the honey mustard sauce. In a small bowl, combine both mustards, honey, apple cider vinegar, salt, pepper, 3 tablespoons of the olive oil, and the grated garlic clove. Whisk it until well combined and then add in the fresh thyme leaves picked from the sprigs. Set aside.
  • Prepare the parsnips. The parsnips should look like french fries when they are prepared. To do this, cut the parsnips in half horizontally. Then, cut the thinner half into quarters (or thinner, if it's a really large parsnip).
    For the thicker top half, cut it in half, lengthwise, and then cut each of those halves in half again. Stand the quarters up on the cutting board, and cut downward from top to bottom to remove the inner woody core. Discard this core, and then cut the remaining parsnips into french fry shapes to match the ones you cut previously.
  • Roast. Place the parsnips on a large baking sheet or baking dish and toss them with the honey mustard sauce, making sure they are spread out into a single layer and are well-coated. Drizzle everything with the remaining tablespoon of olive oil and transfer to the preheated oven. Roast for about 25 minutes, or until the parsnips are golden brown and completely tender when pierced with the tip of a knife. *If the parsnips are not brown enough to your liking, pop them under the broiler for a few minutes and you'll be good to go.
  • Remove from the oven, transfer the hot parsnips to a warm serving dish, and ENJOY!
