Wash, peel and quarter beets. I suggest wearing gloves when working with beets or you'll end up with stained fingers & hands.
Place beets on cookie sheet covered in aluminum foil. Drizzle olive oil over beets, toss until coated.
Generously salt beets.
Bake for 70 - 85 minutes or until beets are fork tender and nicely caramelized. Flip a few times during cooking, add a bit more oil if beets seem to be drying out.
Taste, salt additionly if needed. Lightly drizzle balsamic vinegar over beets if desired. Enjoy!
