Root Vegetables, Low Carb to High Carb: + Root Veggie Recipe

Root Vegetables, Low Carb to High Carb: + Root Veggie Recipe
Home » Recipes by Ingredients » Vegetables » Low carb root vegetables

Although root vegetables are generally higher in carbohydrates than other vegetable choices, if you choose the right ones, and roast them or sauté them without adding sugar or sauces, you can still get high-flavor (and healthy) comfort food without going over your daily carb count. This ”Ragù” recipe is a sauté of root vegetables on the stovetop.

What are Root Vegetables Anyway?

Well, to put it simply they are the vegetables that develop under the soil instead of above. They may have edible greens that grow above ground, but typically the vegetable is thought of as the “tuber” part of the plant instead of the greens.

Generally root vegetables like potatoes, carrots and sweet potatoes are too high in carbs to include in a low-carb or keto diet, but they are still quite healthy and some of the carbs are mitigated by the amount of fiber in these vegetables.

Root vegetables are full of powerful antioxidants, fiber, and beneficial vitamins, so you really don’t want to ignore them…..just don’t make a whole meal out of them.

Lower carb options would include root vegetables like:

  • Onions,
  • Cabbage,
  • Radish,
  • Jicama, and
  • Rutabaga

Here is a list summarizing the carb level from lowest to highest (includes the fiber count):

  • Fennel: 6.4 grams carbs; 3.6 grams fiber

Getting the Most Flavor: Roasting or Dehydrating

Roasting is an extremely popular way to cook these firm vegetables, as it caramelizes them and brings out the sweetness that you don’t get when eaten raw.

A simple sheet pan filled with root vegetables and placed in a 425 degree F oven for 30-40 minutes is a very easy and increasingly popular way to roast root vegetables. Just sprinkle them with your favorite spice and drizzle with olive oil before roasting.

The spices you choose will allow you to change up the flavor profile so as not to get bored.

Add some chicken or fish to the cookie sheet and you have what is referred to as a “sheet pan dinner”, or as the Brits would say….”a traybake”.

One of my favorite Fall dishes is this recipe for a sheet-pan roasted root veggies with a breaded pork chop. Of course the breaded pork chop is not low carb, but it’s easy to modify if you want to comply with a low carb lifestyle (just cook without the breading!)

How to Roast Veggies without Oil

A drizzle of oil on the ingredients prior to roasting can certainly help to prevent the ingredients from drying out in the hot oven. Olive oil is my oil of choice, but if you prefer no oil at all, you can steam the veggies first and then finish in the oven.

Steaming works well, but it does add an extra step, so if it keeps you from cooking nutritious root veggies, just add a drizzle of oil and call it good.

Dehydrated Vegetable Chips

Root vegetables are the perfect foil for making a crunchy, crispy low carb snack. They are firm and not filled with water, allowing them to turn crispy in the dehydrator.

Just use a dehydrator that has temperature controls so that you can adjust based on the vegetable. We grow chile peppers and tomatoes and dry them for our online spices all Fall, and so I’ve gone through a lot of dehydrators.

If you plan to do much dehydrating of produce, this Gardenmaster dehydrator has been the most reliable workhorse for me.

The best thing about making vegetable chips is the flexibility you have with the seasonings. You can give them a Mexican flair, a Moroccan taste, a Korean twist, etc. Here are some of my favorite ways to make vegetables in the dehydrator.

How to Store Raw Root Vegetables

Most root veggies can be stored one of two ways: wrapped and in the crisper drawer of the refrigerator, or in your pantry in a cool, dark, dry place. I store radishes, carrots, jicama and parsnips in the crisper drawer and then place onions and potatoes in a cool (55 to 60 degrees F) dark place that is dry.

Most of the root vegetables you get at the store have been cured and should keep for a month or more.

If you plan to keep your vegetables for a long time, this post from The Spruce gives you detailed instruction for each of the different root vegetables.
