For an extra layer of flavor, consider adding a pinch of nutmeg or a dash of hot sauce to the onion mixture. If you prefer a sharper cheese, you can substitute some of the Monterey Jack with Gruyere or sharp cheddar. To prevent the crust from browning too quickly, you can cover the edges with foil during the last 15 minutes of baking. This tart is delicious served warm or at room temperature. It can also be made ahead of time and reheated gently before serving.

Jun 18, 2025My crust browned too quickly, even with foil. Next time, I'll try blind baking it for a few minutes first.
