Step‑by‑Step Instructions for Leek, Sausage & Butternut Squash Tart
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (350°F). This step is essential to ensure your Leek, Sausage & Butternut Squash Tart bakes evenly and achieves that perfect golden crust. While the oven warms up, gather your ingredients and prepare your workspace for a smooth cooking experience.
Step 2: Prepare the Pastry Crust
Roll out your pastry dough on a lightly floured surface until it’s about ¼ inch thick. Carefully fit the rolled pastry into a tart pan, pressing it against the edges. Trim any excess pastry hanging over the sides. A neatly shaped crust provides the perfect base for the savory filling, so take your time to get it right.
Step 3: Sauté the Vegetables and Sausage
In a large sauté pan over medium heat, add a splash of oil and toss in the chopped leeks and your choice of sausage. Cook for about 5–7 minutes, stirring occasionally, until the leeks are softened and translucent, and the sausage is browned and cooked through. Drain any excess moisture to prevent a soggy tart.
Step 4: Whisk the Egg and Cream Mixture
In a mixing bowl, whisk together the eggs and cream until well combined. This mixture will create the custard base for your filling. Once mixed, gently fold in the sautéed leeks and sausage, ensuring everything is evenly distributed. This rich filling will bring depth to your Leek, Sausage & Butternut Squash Tart.
Step 5: Fill the Tart Shell
Pour the creamy leek and sausage mixture into the prepared pastry crust, spreading it evenly to cover the base. Be careful not to overfill, as the mixture will puff slightly while baking. This step is crucial for achieving a beautiful presentation and prevents any spillage while in the oven.
Step 6: Bake the Tart
Place the tart in the preheated oven and bake for 30–35 minutes. You’ll know it’s ready when the filling is set, lightly puffed, and the pastry is a lovely golden brown. Keep an eye on it after the 30-minute mark to avoid over-baking, as each oven varies slightly.
Step 7: Cool and Serve
Once baked, carefully remove the tart from the oven and let it cool for about 10 minutes before slicing. This resting period helps the filling set and makes it easier to cut neat slices. Serve your warm Leek, Sausage & Butternut Squash Tart to family and friends—it’s bound to be a hit!

Leek, Sausage & Butternut Squash Tart Recipe FAQs
How do I select ripe leeks?
When choosing leeks, look for firm stalks that are bright green with no signs of wilting or dark spots. The white part should be clean and intact, as blemishes can indicate age or spoilage.
How should I store leftovers from the tart?
Store any leftover Leek, Sausage & Butternut Squash Tart in an airtight container in the refrigerator for up to 3 days. This keeps the flavors fresh and the texture intact for your next meal!
Can I freeze the tart?
Absolutely! To freeze, let the tart cool completely, then slice it into individual portions. Wrap each slice tightly in plastic wrap, followed by aluminum foil, and store in a freezer-safe bag. It can be kept for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight and reheat in a preheated oven at 180°C (350°F) for about 10-15 minutes until warmed through.
What if my tart turns out soggy?
Sogginess is often caused by excess moisture in the filling. To avoid this, make sure to sauté the leeks and sausage thoroughly, allowing any released moisture to evaporate. Also, consider draining any frozen butternut squash before adding it to the mixture. If you do end up with a soggy tart, reheating it in the oven can help crisp it up slightly.
Is this recipe suitable for vegetarians?
Yes, you can easily make the Leek, Sausage & Butternut Squash Tart vegetarian by substituting the sausage with a plant-based option. I often use crumbled vegetarian sausage or even feta cheese for an exciting twist, which complements the flavors beautifully!
