"[Photographs: Elizabeth Barbone] These savory muffins welcome variations. Variations: For Garlic Bread Muffins: Omit the onion. Increase garlic to five cloves and parmesan cheese to 1/2 cup. For Herb Muffins: Stir 1 tablespoon of dried herbs into the batter. For milder herbs, like basil, consider increasing the amount to 1 1/2 tablespoons. For stronger herbs, like rosemary, reduce amount to 2 teaspoons. For Caramelized Onion Muffins: Add 1/2 cup cooled caramelized onions to the batter. For Dairy-Free Muffins: Replace the milk with dairy-free milk and omit cheese. Dairy-free muffins bake off lighter than muffins with dairy.
