Tips & Substitutions
For a deeper flavor, consider adding herbs like thyme or chives to the onion mixture. If you're short on time, pre-cooked caramelized onions can serve as a time-saving substitute. You can also use a store-bought pastry shell to simplify the process. If you want a lighter version, substitute half of the heavy cream with milk or a non-dairy alternative.
Serving Suggestions
Serve the Swiss Onion Tart warm or at room temperature, making it perfect for brunch or a light lunch. Pair it with a fresh salad or Cucumber Rounds for a refreshing contrast. A glass of white wine or a light beer would complement the tart's rich flavors beautifully.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, place the tart in a preheated oven at 350°F for about 15-20 minutes, or until warmed through. This will help maintain the crispness of the pastry while warming the filling evenly.
