It’s Always a Good Time For Pie
If there’s one thing I’ll never say no to, it’s squash—especially when it’s cooked into a savory pie with caramelized onions and bacon. This recipe is basically my love language in edible form. A buttery, flaky crust filled with sweet onions, golden squash, crispy bacon, and gooey Gruyère cheese? Come on. Who can say no to that?
Now, I know caramelizing onions takes time (40 whole minutes!), but hear me out—it’s absolutely worth it. This is the kind of dish that looks like you put in way more effort than you did.
And the result? A golden, bubbling, cheesy pie that’s the centerpiece of any brunch table—or, you know, just dinner on a Wednesday when you want to feel fancy.
And let’s not overlook the homemade pie crust—it’s buttery, flaky, and absolutely worth the chill time in the fridge. But if you cheat and use a store-bought pie crust, I won’t judge. Well…maybe.
Why this Recipe Works
•Caramelized onions add a deep, sweet flavor that balances the richness of the bacon and cheese.
•Summer squash brings a fresh spring note and tender bite.
•Homemade pie crust gives it a rustic, buttery base that beats store-bought every time.
•Gruyère cheese melts beautifully and adds nutty, savory depth.
• Perfect for brunch, lunch, or leftovers—this pie reheats like a dream.
Tips for Making Squash, Caramelized Onion, and Bacon Pie
•Use a mandoline to slice the squash evenly for consistent cooking.
•Don’t rush the onions—low and slow is the way to go for perfect caramelization.
•Make the pie crust a day ahead and chill overnight to save time.
•Want to make it vegetarian? Skip the bacon and add mushrooms or sun-dried tomatoes.
•Serve with a light salad and a crisp white wine (because you deserve it).

Make the Pie Dough
Cut the butter into small cubes. Combine the butter and flour in a mixing bowl. Using a pastry blender or your fingers, work the butter into the flour. Add the salt and sugar. Continue to work the butter into the flour until the mixture is a consistency of ground cornmeal. The cubes of butter should be the size of a pea.
Handle the dough as little as possible. The more you work and handle it, the warmer the ingredients. If it gets too warm, put the bowl in the fridge to chill. -
Add the water, all at once. Continue to work the dough until the dough begins to come together. Form the dough into a ball, wrap with plastic wrap, and press into a disk. Place in the fridge for 2 hours to chill.
-
Remove the dough from fridge and roll into a 12-inch circle. Place into a 9-inch round pie plate. Prick the dough with a fork on the bottom and up the sides of the plate. Place in freezer for 30 minutes before baking. Preheat the oven to 375°F.
When rolling out the dough, roll from the center to the edges. Then quarter turn the dough and roll from the center and back out to the edge again. Continue quarter turning the dough and repeating this process until a nice even circle is formed. -
Remove the dough from the freezer and line the dough with parchment paper, completely covering the surface. Fill the pie plate with pie weights. This will ensure that the dough maintain it's shape while baking. Bake for 12-15 minutes. Remove the pie weights and parchment. Set on counter to cool.

Note
The trick to making pie dough is using cold ingredients. I even chill the flour, salt, and sugar. Place the dry ingredients into the bowl and put entire bowl into the fridge to chill.
