Preheat the oven to 375 degrees. Coat a baking sheet with a bit of olive oil.
Place the baby carrots, fennel, and shallot together on the baking sheet with some of the garlic-infused olive oil (or plain is fine too). Season with sea salt and freshly cracked pepper, to taste. Toss to coat evenly.
Place into the oven and roast for 30-40 minutes, tossing every 10 minutes or so to prevent burning.
Remove from the oven and serve immediately. Enjoy.
