List of Root Vegetables

Classic & Common Root Vegetables

  • Carrots – Sweet, crisp, and perfect for roasting or raw snacking.
  • Potatoes (white, red, gold) – Starchy and versatile; great mashed, roasted, or fried.
  • Sweet Potatoes – Naturally sweet and creamy when cooked; great in both savory and sweet dishes.
  • Beets (red, golden, chioggia) – Earthy flavor and vibrant color; excellent roasted or pickled.
  • Parsnips – Mildly sweet and nutty; great roasted or puréed.
  • Turnips – Slightly peppery; wonderful in soups and stews.
  • Rutabaga (Swede) – Cross between a cabbage and a turnip; sweet and dense.

Hearty & Less Common Root Veggies

  • Celery Root (Celeriac) – Mild celery flavor; delicious mashed or in soups.
  • Radishes (red, daikon, watermelon) – Peppery raw, mellow when roasted.
  • Sunchokes (Jerusalem Artichokes) – Nutty and slightly sweet; best roasted or sautéed.
  • Yuca (Cassava) – Dense and starchy; used in Latin American and African cuisines.
  • Taro – Earthy and slightly nutty; often used in Asian dishes.
  • Lotus Root – Crunchy and slightly sweet; common in Asian cooking.

Ingredients You’ll Need

  • 3 pounds of root vegetables – In this recipe, we chose to use a combination of carrots, parsnips, sweet potatoes, and beets.
  • Red Onion – Adds balance and light sweetness. I used red onion mostly because I think the color is beautiful when it is roasted. Yellow or white onions also works and tastes just as good.
  • Olive Oil – Enhances flavor and helps crisp the veggies. Avocado oil is a great substitute.
  • Kosher Salt – Brings out natural flavors; sea salt also works well.
  • Black Pepper – Adds just enough spice to balance the sweetness.
  • Fresh Rosemary – Classic herb pairing; thyme or sage make excellent swaps.

Instructions

Step 1 – Prepare oven. Preheat oven to 425°F.

Step 2 – Cut vegetables. Peel and cube all vegetables into ½-inch pieces. Keep beets in a separate bowl to avoid staining the others.

Step 3 – Add oil. Toss beets with 1 tbsp olive oil, ½ tsp salt, ½ tbsp rosemary, and a pinch of black pepper. Toss remaining veggies with the rest of the olive oil, salt, rosemary, and pepper.

Step 4 – Add to pan. Spread evenly on a parchment-lined baking sheet. Scatter beets among the other vegetables.

Step 5 – Cook. Roast for 45 minutes, stirring once halfway through, until tender and golden brown.

Step 6 – Serve. Serve warm as a side dish—or make it a main with your favorite grain or protein.

Pro Tip: Cover the baking pan with aluminum foil. It prevents sticking and makes cleanup easier.

Frequently Asked Questions (FAQs)

Can I prep the veggies ahead of time?

Yes! Chop everything a day ahead and store in airtight containers in the fridge.

What’s the best way to reheat them?

Oven or air fryer. Avoid the microwave if you want them crispy.

Can I use frozen vegetables?

Fresh is best for roasting. Frozen veggies tend to steam and get mushy.

How can I make this dish vegan or Whole30-friendly?

It’s naturally vegan and Whole30-compliant—just make sure your oil and spices are compliant if you’re following a strict plan.

Do I need to peel the vegetables?

Peeling is recommended, especially for beets and parsnips, but you can leave the skins on carrots and sweet potatoes if well-scrubbed.

Ingredients

  • 3 pounds Root vegetables, such as carrots, parsnips, sweet potatoes, and beets
  • 1 small Red onion
  • 1/4 cup Olive oil
  • 1 1/2 teaspoons Kosher salt
  • 1/4 teaspoon Freshly ground black pepper
  • 2 tablespoons Coarsely chopped fresh rosemary leaves

Instructions

  • Preheat oven to 425°F.
  • Peel vegetables and cut into 1/2 -inch cubes. Place all cut vegetables into a large bowl EXCEPT for the beets. Place those in their own smaller bowl. This will prevent the red juice from getting all over your other vegetables when you toss them in oil.
  • Pour one tablespoon of the olive oil over the beets and toss them in it until coated.
  • Pour the remaining oil over the other vegetables tossing them until coated.
  • Sprinkle ½ teaspoon of salt, ½ tablespoon of rosemary, and a pinch of black pepper over the beets. Sprinkle the remaining salt, rosemary, and pepper over the other vegetables. Toss both bowls so the beets and vegetables are coated in the seasoning.
  • Place root vegetables on your baking sheet and then evenly distribute the beets amongst the vegetables.
  • Bake for 45 minutes until softened and slightly browned.
  • Remove from oven and let cool slightly before serving.
