About Onion tart

Onion tart is a savory dish originating from French cuisine, particularly from the Alsace and Lorraine regions. It combines caramelized onions, cream, eggs, and sometimes cheese, baked in a pastry crust. It’s a rich and flavorful dish often enjoyed as an appetizer or main course. While onion tart is calorie-dense due to its use of cream and pastry, onions themselves are a good source of vitamin C, fiber, and various antioxidants like quercetin. The eggs and cream contribute protein, calcium, and vitamin D, making it a balanced but indulgent dish. However, its high fat and sodium content may not suit individuals with specific dietary needs.

Health Benefits

• Onions are rich in antioxidants like quercetin, which support cellular health and reduce inflammation.
• Eggs in the tart provide choline, a nutrient crucial for brain health and memory function.
• Cream contributes calcium, essential for maintaining strong bones and teeth.
