Tips & Substitutions
For a richer flavor, consider using caramelized onions instead of raw. If you're short on time, pre-sliced onions can be a great time-saver. You can substitute the mild Wisconsin cheese with cheddar or Monterey Jack for a different taste. For a crunchier texture, add some crushed garlic croutons on top before baking.
Serving Suggestions
