Roasted Root Veggie Health Benefits

Blood Sugar Regulating: Turnips, rutabagas, and radishes are all cruciferous root vegetables that are generally considered “non-starchy” despite containing some starch. This trio delivers a variety of vitamins and minerals with less impact on blood sugar than starchy potatoes.

Liver Detoxification: Radishes and turnips may support the liver’s natural detoxification process, while the fiber from all three vegetables aids in healthy digestion and elimination.

Anti-Inflammatory: When paired with anti-inflammatory garlic and rosemary, this easy roasted root vegetables recipe is a tasty way to introduce more variety into your meals.

Ingredients

This beautiful combination of roasted root veggies is a favorite of mine. Their seasons coincide in the fall, making grocery shopping efficient.

RADISHES – Roasting softens the sharp bite of radishes, resulting in mild flavor with subtle sweetness. Red radishes are easiest to find, but Easter egg radishes add vibrant color if you’re feeling fancy. If they’re particularly large, cut them into eighths for even cooking.
TURNIPS – Smaller turnips tend to be less bitter so look for ones about 4 inches in diameter or smaller.
RUTABAGA – One soft-ball-sized rutabaga is plenty. Peeling isn’t necessary unless the skin is particularly gnarly, or wax-coated.

How to Make Roasted Root Vegetables

Heat oven to 375º F. Set a casserole dish with an inch of water on the bottom rack of the oven. Line a rimmed baking sheet with unbleached parchment paper.
Toss the chopped veggies in a large mixing bowl and drizzle with 1 tablespoon of extra virgin olive oil. Sprinkle with 1 tablespoon chopped rosemary, ½ teaspoon granulated garlic, and ½ teaspoon salt. Using your hands, massage the oil and seasonings into the veggies until evenly coated and spread in an even layer on a rimmed baking sheet. Bake until golden and easily pierced with a fork, about 20-25 minutes. CAUTION! Stand back when opening the oven so the steam doesn’t burn you!
Remove the roasted root veggies from the oven and serve with your favorite protein and greens. Season to with salt and fresh pepper taste.
Refrigerate any leftovers in a sealed glass container for 3-5 days.

Recipe Tips

Simplify prep: Save time by opting for a 12-ounce bag of pre-trimmed radishes instead of a bunch with greens attached.
Cut uniform pieces: Chop the vegetables to a similar size for even cooking. If radishes are large, cut them into eighths rather than quarters.
Spread evenly: Arrange the veggies in a single layer to allow proper air circulation, ensuring a better roast.
Optional browning: For extra caramelization, remove the dish of water from the oven once the veggies are fork-tender and roast for an additional 5-10 minutes. Keep an eye on them to prevent the rosemary from burning.
