- Add a sprinkle of chopped walnuts or pecans for extra crunch and richness.
- For a vegetarian option with extra depth, drizzle a little honey over the tarts before baking.
- If fresh thyme isn’t available, substitute with rosemary or oregano for a different herbal note.
Storage
Store any leftover tarts in an airtight container in the refrigerator for up to 2 days. Reheat gently in an oven or toaster oven at 350°F (175°C) for 5–7 minutes to restore crispness. Avoid microwaving to keep the pastry flaky.
