How to Make Savory Butternut Squash Pie Recipe
Step 1: Roast the Butternut Squash
Start by peeling and dicing your butternut squash into small, even pieces about ¼-inch thick. Toss them with 2 tablespoons of olive oil and a generous pinch of coarse kosher salt. Spread evenly on a baking sheet and roast in a preheated oven at 400°F until tender and caramelized, usually about 25 to 30 minutes. This step transforms the squash into a sweet, soft base that fills the pie with warmth and silkiness.
Step 2: Caramelize the Onions
While the squash roasts, slice your onions thinly and cook them low and slow with 1 tablespoon of olive oil in a large skillet over medium-low heat. Stir occasionally to develop a deep golden-brown color, which should take around 40 minutes. Stir in a splash of balsamic vinegar at the end for complexity and to brighten those rich onion flavors.
Step 3: Prepare the Custard
In a mixing bowl, whisk together the eggs, whole milk, and heavy cream. Add apple cider vinegar or lemon juice for acidity, then season with coarse kosher salt and freshly ground black pepper. This silky custard will hold the filling together and offer that luscious, creamy texture that makes this pie unforgettable.
Step 4: Assemble the Pie
Lay your prepared pie crust in a 9-inch pie dish and gently prick the bottom with a fork to prevent bubbling. Combine the roasted squash, caramelized onions, and fresh thyme leaves in a bowl, then gently fold in the custard mixture. Pour this filling evenly into the crust. Sprinkle crumbled feta cheese and sliced green onions on top for bursts of flavor and color before placing the pie in the oven.
Step 5: Bake to Perfection
Bake your Savory Butternut Squash Pie Recipe at 375°F for about 40 minutes or until the custard is set and the crust is golden brown. Let it cool for at least 10 minutes before slicing so the filling can firm up, making every slice neat and satisfying.
How to Serve Savory Butternut Squash Pie Recipe

Garnishes
Add a fresh splash of color and flavor with extra thyme leaves or a handful of chopped fresh herbs like parsley or chives. A light drizzle of good-quality olive oil or a dollop of sour cream can elevate each slice with wonderful richness and freshness.
Side Dishes
This pie pairs beautifully with crisp green salads featuring lemon vinaigrette or roasted vegetables like Brussels sprouts or asparagus. The combination of fresh, crunchy sides with the pie’s creamy texture keeps your meal balanced and exciting.
Creative Ways to Present
Serve individual mini pies for a charming appetizer or create a beautiful open-faced tart variation by skipping the top crust and layering decorative slices of squash and onions. This gives a rustic yet elegant presentation that guests will love.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover pie tightly with plastic wrap or cover with foil, and store it in the refrigerator for up to 3 days. The flavors continue to meld beautifully overnight, making leftovers even more delicious.
Freezing
For longer storage, you can freeze the pie whole or in individual slices. Wrap tightly with plastic wrap followed by aluminum foil to prevent freezer burn. The pie can be frozen for up to 2 months without losing quality.
Reheating
Reheat slices in an oven set at 350°F for about 15 to 20 minutes until warmed through and the crust crisps back up. Avoid the microwave if you want to maintain that wonderful flaky texture of the crust.
FAQs
Can I use a different type of cheese instead of feta?
Absolutely! While feta offers a lovely tangy contrast, goat cheese or ricotta would work well for a milder, creamy flavor that complements the sweetness of the squash.
Is it possible to make this pie vegan?
Yes, by substituting the eggs and dairy with plant-based alternatives like silken tofu or cashew cream, and using a vegan pie crust, you can create a delicious vegan version of this recipe.
What can I do if I don’t have balsamic vinegar?
You can replace balsamic vinegar with a splash of apple cider vinegar or lemon juice for acidity, just keep it moderate to avoid overpowering the sweetness of the onions.
Can I prepare the caramelized onions in advance?
Certainly! Caramelized onions keep well in the refrigerator for up to 4 days, so making them ahead can save time and deepen the flavors.
What type of pie crust works best?
Both spelt and butter-based pie crusts are wonderful for this recipe. Spelt brings a heartier texture and nuttiness, while butter crust offers classic flakiness and richness.
Final Thoughts

Instructions
- Prepare Butternut Squash: Peel and dice the butternut squash into ¼-inch pieces, yielding approximately 2 and a half cups. Toss the squash with 2 tablespoons of olive oil and a sprinkle of coarse kosher salt. Spread evenly on a baking sheet.
- Roast Squash: Roast the butternut squash in a preheated oven at 400°F (200°C) for about 25-30 minutes until tender and caramelized, stirring halfway through for even cooking. Remove from the oven and set aside to cool slightly.
- Caramelize Onions: While the squash roasts, heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions with a pinch of coarse kosher salt and cook slowly, stirring occasionally, for about 25-30 minutes until deeply browned and caramelized. Towards the end, stir in the balsamic vinegar and cook for an additional 2 minutes to meld flavors. Remove from heat and let cool.
- Prepare Custard Mixture: In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, apple cider vinegar (or lemon juice), 1 teaspoon kosher salt, and freshly ground black pepper until fully combined.
- Assemble the Pie: Lay the prepared pie crust in a 9-inch pie dish. Combine the roasted butternut squash and caramelized onions and evenly distribute over the crust. Pour the custard mixture evenly over the vegetables. Sprinkle the top with crumbled feta cheese, sliced green onions, and fresh thyme leaves for added aroma and flavor.
- Bake the Pie: Place the pie in the preheated oven at 375°F (190°C) and bake for about 35-40 minutes, until the custard is set and the top is golden brown. A knife inserted in the center should come out clean.
- Cool and Serve: Allow the pie to cool for at least 10-15 minutes before slicing to help the filling set properly. Serve warm or at room temperature, and enjoy this savory seasonal treat!
Notes
- Coarse kosher salt is used throughout for seasoning; adjust the quantity to taste but be mindful of the feta cheese’s saltiness.
- Use either spelt pie crust or butter pie crust depending on dietary preference.
- Roasting the squash before baking enhances its sweetness and texture in the pie.
- Caramelize onions slowly over medium heat; rushing this step can result in uneven flavor development.
- This pie can be reheated and served as leftovers or made ahead and refrigerated overnight.
