Preheat oven to 425 degrees F. Peel the parsnips, and cut them into coins. If they are quite wide, and the core is thick, you may need to trim around the core. The core can be kind of tough if the parsnip is very wide.
Place the peeled and sliced parsnips, minced garlic, and olive oil on a baking sheet lined with parchment paper.
Sprinkle with salt and pepper. Use your hands to make sure the parsnips are evenly coated.
Bake at 425 degrees for about 30 minutes until parsnips are tender and a little brown on the edges. Stir once during the cooking time.
Season with more salt and pepper if desired.
Notes
Try to choose parsnips that are about one inch in diameter at the top. If they are too wide, then may be tough or woody in the middle. Store leftover roasted parsnips in the refrigerator. They should stay fresh for about 4 days.You can garnish these with any fresh herbs that you like. Try thyme, basil, or sage.
