Peel, trim ends, and cut carrots into equal-sized pieces about 2 inches long.
Place carrots on a 9-by-13-inch baking sheet, leaving a little space between carrots. Drizzle with 2 tablespoons olive oil and mix to coat.
Sprinkle with red pepper flakes, if using.
Place carrots in oven and roast for 15 minutes.
While roasting, whisk together the maple syrup, soy sauce, and remaining olive oil in a small bowl.
Remove carrots from oven and drizzle with the maple syrup mixture. Turn carrots gently to coat.
Return carrots to oven. Roast 10-15 minutes longer, or until carrots are tender. Carrots are done when a fork can be inserted easily.
Serve immediately or cover and refrigerate for up to two days.
Notes
Change it Up
Replace the soy sauce with balsamic vinegar.
Sprinkle with 2 tablespoons fresh thyme or sprigs of fresh thyme before roasting.
Skip the maple syrup mixture in Step 7. Halfway through cooking, toss the carrots with ⅓ cup grated Parmesan cheese and 2 teaspoons minced garlic instead.
