📖 Instructions

1. **Prepare the Dough (if not using pre-made):** In a large bowl, whisk together 1½ cups all-purpose flour, ½ teaspoon salt, and 1 tablespoon granulated sugar. Cut in 1 stick (½ cup) unsalted butter, cubed and very cold, using a pastry blender or your fingertips, until the mixture resembles coarse meal with some pea-sized pieces of butter remaining. Gradually add 4-6 tablespoons of ice water, one tablespoon at a time, mixing until the dough just comes together. Be careful not to overmix. Form the dough into a disk, wrap it tightly in plastic wrap, and refrigerate for at least 30 minutes, or up to 2 days. This chilling step is really important for a flaky crust!
2. **Preheat Oven and Prepare Baking Sheet:** Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper. This prevents sticking and makes cleanup a breeze, believe me.
3. **Prepare the Fruit Filling:** In a large bowl, gently combine 3 cups sliced strawberries (halved or quartered depending on size) and 2 cups chopped rhubarb (cut into ½-inch pieces). Add ½ cup granulated sugar (adjust to your sweetness preference and the tartness of your rhubarb), 2 tablespoons all-purpose flour (this helps absorb excess liquid and thicken the filling), ½ teaspoon vanilla extract, and a pinch of salt. Toss everything together until the fruit is evenly coated. Sometimes, I like to add a tiny bit of lemon zest here for an extra zing!
4. **Roll Out the Dough:** On a lightly floured surface, roll out the chilled dough into a rough 12-14 inch circle, about ⅛ to ¼ inch thick. Don't stress about making it a perfect circle; the rustic look is part of its charm! Carefully transfer the rolled dough to your prepared baking sheet. If it tears a little, just patch it up with your fingers.
5. **Assemble the Galette:** Spoon the strawberry-rhubarb filling onto the center of the dough, leaving a 2-inch border around the edges. Try to mound the fruit slightly in the middle. Now, with a little finesse, fold the edges of the dough up and over the fruit, pleating it as you go. The center of the fruit will remain exposed. See? Easy-peasy!
6. **Egg Wash and Sugar Sprinkle:** In a small bowl, whisk 1 large egg with 1 tablespoon of water to create an egg wash. Brush the egg wash generously over the folded crust. This gives it that beautiful golden-brown sheen. Then, sprinkle 1 tablespoon of coarse turbinado sugar (or granulated sugar) over the egg-washed crust. This adds a lovely sparkle and a slight crunch.
7. **Bake the Galette:** Transfer the baking sheet to the preheated oven. Bake for 35-45 minutes, or until the crust is deeply golden brown and the fruit filling is bubbly and tender. If you notice the crust browning too quickly, you can loosely tent it with aluminum foil. Oven temperatures can vary, so keep an eye on it!
8. **Cool and Serve:** Once baked, remove the galette from the oven and let it cool on the baking sheet for at least 15-20 minutes before slicing. This allows the filling to set properly, preventing a runny mess. Trust me, patience here is a virtue! Serve warm, perhaps with a scoop of vanilla ice cream or a dollop of whipped cream. Enjoy every single bite of this summer delight!
9. **Storage:** Leftovers can be stored loosely covered at room temperature for up to 2 days, or refrigerated for up to 4 days. Reheat briefly in a warm oven for best results.
