Ingredients for French Onion Tart

- 1 tablespoon butter
- 1 teaspoon sugar (to help caramelize those onions perfectly)
- 1 teaspoon salt
- 1 teaspoon dried thyme (or fresh if you have it on hand)
- 1 cup heavy cream (for that luscious, creamy filling)
- 2 large eggs (make sure they’re fresh!)
- 1 pre-made pie crust (you can make your own if you’re feeling adventurous!)

How to Prepare French Onion Tart
Now that we’ve got our ingredients lined up, it’s time to dive into the delightful process of making this French onion tart! I promise, it’s easier than it sounds. Let’s break it down step-by-step so you can enjoy every moment of this savory creation.
Step-by-Step Instructions
- First things first, preheat your oven to 375°F (190°C). This is crucial to ensure your tart bakes evenly and comes out perfectly golden!
- While the oven heats up, grab a large skillet and heat the olive oil and butter over medium heat. You want that butter to melt and start bubbling, but not browning. Careful now!
- Next, add those thinly sliced onions to the pan. Sprinkle in the sugar and salt, and give it a good stir. We want to cook these babies down until they’re soft and beautifully caramelized, which usually takes about 20-25 minutes. Just keep an eye on them and stir occasionally to prevent sticking.
- Once your onions are a rich, golden color, toss in the thyme and let it cook for another minute to release that lovely aroma.
- In a separate bowl, whisk together the heavy cream and eggs until well combined. You want this mixture to be smooth and creamy, so give it a good whisk!
- Now, it’s time to fold those caramelized onions into the cream mixture. Make sure it’s all mixed together nicely, so every bite of your tart is bursting with flavor.
- Pour this delicious filling into your pre-made pie crust, spreading it out evenly.
- Finally, sprinkle the grated Gruyère cheese generously on top. This is where the magic happens—trust me, you want that melty goodness!
- Pop the tart into the oven and bake for about 30-35 minutes. You’ll know it’s done when the filling is set and the top is golden and bubbly. Oh, the smell will be heavenly!
- Once it’s out of the oven, let it cool for a few minutes before slicing. This allows the filling to firm up a bit, making it easier to serve. Just try to resist diving in right away!
And there you have it—a scrumptious French onion tart that’s sure to impress! Can’t wait for you to taste it!
