Pre-heat oven to 350℉. Cut the vegetables as explained above. Remember to cut it lengthwise if you can.
2 sweet potatoes, 4 shallots, 1 yellow onion, 6 carrots
Tear off 3 or 4 large pieces of heavy-duty foil.
Put each type of vegetable in it's own packet. Place on the lower edge of the foil - leave enough room to fold and seal the foil.
Drizzle olive oil on vegetables.
3 tablespoons olive oil
Sprinkle onion powder, garlic powder, salt, and pepper.
2 teaspoons onion powder, 2 teaspoons garlic powder, 1/2 teaspoon salt, 1/16 teaspoon pepper
Fold foil over vegetables and seal by scrunching the ends together.
Place foil packets on jelly roll pans and bake for 40 minutes. After 30 minutes, don an oven mitt and gently press down on the vegetables. If any vegetable is soft to the touch, take it out of the oven. Otherwise, these vegetables take 40 minutes.
Unwrap foil carefully so you're not burned by escaping steam.
Transfer the contents of the packets including the juices to a serving bowl.
Serve, eat, and enjoy.
