How to Make Onion and Blue Cheese Tart
Prepare the Crust: In a large mixing bowl, combine the all-purpose flour and salt. Cut in chilled unsalted butter until the mixture resembles coarse crumbs. Gradually add ice water until the dough holds together. Form into a ball, wrap in plastic, and refrigerate for 30 minutes.
Caramelize the Onions: Slice your onions thinly. In a skillet, melt a bit of butter over medium heat, adding the onions. Cook slowly, stirring occasionally, for about 20-30 minutes, until they are golden brown and sweetly fragrant.
Roll Out the Dough: Preheat your oven to 375°F (190°C). On a floured surface, roll out the chilled dough into a 12-inch circle and carefully fit it into a tart pan. Trim any excess dough and prick the bottom with a fork to prevent bubbling.
Mix the Filling: In a medium bowl, whisk together heavy cream, eggs, black pepper, and a pinch of salt. Fold in the caramelized onions and crumbled blue cheese until well combined.
Assemble and Bake: Pour the filling mixture into the prepared crust, spreading it evenly. Bake in the preheated oven for 30-35 minutes or until the filling is set and the top starts to turn golden.
Cool and Serve: Allow the tart to cool for a few minutes before slicing. Serve warm or at room temperature, and enjoy every savory bite!
Optional: Drizzle with honey for a balanced sweetness.

Onion and Blue Cheese Tart Recipe FAQs
What kind of onions are best for caramelizing?
Sweet onions like Vidalia, Walla Walla, or yellow onions are ideal for caramelizing due to their high sugar content. They become beautifully sweet and tender when cooked slowly, enhancing the overall flavor of your tart.
How should I store leftover Onion and Blue Cheese Tart?
To keep your tart fresh, store it in an airtight container in the fridge for up to 3 days. This keeps the creamy filling moist and prevents the crust from becoming stale. If you want it to last longer, you can freeze it.
Can I freeze Onion and Blue Cheese Tart?
Absolutely! Wrap your cooled tart tightly in plastic wrap, ensuring no air escapes, then follow with a layer of aluminum foil. This will keep it fresh for up to 3 months. When you’re ready to enjoy it, let it thaw in the fridge overnight and then reheat in a preheated oven at 350°F (175°C) for about 15-20 minutes.
What if my tart crust shrinks while baking?
To avoid shrinkage, make sure your dough is well-chilled before rolling it out. Also, avoid overworking the dough, as this can lead to gluten development, causing shrinkage during baking. Pricking the bottom of the crust with a fork can help prevent bubbling and shrinkage too.
Is there a gluten-free alternative for the crust?
Yes! You can use a gluten-free flour blend to make the crust. Just make sure to add a bit of xanthan gum if it’s not included in the blend, as this helps mimic the texture of traditional flour. Look for a recipe specific to gluten-free tart crusts for best results.
Can I make this recipe vegetarian-friendly?
Certainly! Simply omit the chicken bouillon powder or replace it with a vegetable bouillon powder. This will keep the savory flavor profile intact while making it suitable for vegetarians.
