Herb Roasted Sweet Potatoes

This is a Martha Stewart recipe. It's really good.

3-4 sweet potatoes, peeled & cut into 1.5" rounds
3 Tablespoons olive oil
1 Tablespoon fresh thyme leaves (or ~1 teaspoon dry thyme)
2 small cloves garlic, minced
1/4 teaspoon crushed red-pepper flakes
1 teaspoon coarse salt

1. Preheat oven to 400 degrees F. In a medium-large bowl, toss the sweet potato rounds w/olive oil, thyme, garlic, red pepper, and salt.

2. Transfer to a rimmed baking sheet, garnish w/thyme sprigs if you like, and place in oven. Roast until tender and starting to brown, 40-45 minutes.
