In your crockpot, combine onions, butter, olive oil, salt, and pepper. Cook on low for 8 hours until onions are golden brown. Add in balsamic vinegar and broth; cover and continue cooking on low for an additional 6 hours. Ladle soup into bowls, top with Gruyere cheese, and broil in the oven until top is golden.
