The zucchini is the heart of this pie, so choose firm, medium-sized ones—they'll be sweeter and less watery. Trader Joe's or local farmers' markets often have the freshest zucchini, but grocery store produce works too. Grilling them first removes excess moisture, which is key for a light filling. My grandmother always used organic zucchini from the garden when she could, but conventional works just fine. Look for vibrant green skin with no soft spots—they should feel heavy for their size, indicating freshness.
No sharp cheddar? Pepper jack or Gruyère add nice depth, though the flavor will shift slightly. The eggs must be room temperature—they blend smoother and create a lighter texture. Kirkland Signature or Organic Valley eggs are reliable choices if you're buying store-brand. For the lattice, King Arthur flour yields the best results—it has a higher protein content that creates a more tender crust. Substituting all-purpose flour works, but the texture won't be quite as delicate. The baking powder is crucial—Aluminum-free brands like Bob's Red Mill prevent any metallic aftertaste.
This pie keeps beautifully—3-4 days in the fridge wrapped tightly in foil. For longer storage, freeze portions for up to 3 months. I always bake an extra crust to make mini pies for lunches. The lattice design stays crisp for 2 days at room temperature if stored in an airtight container. Reheat slices in a 350°F oven for 10 minutes to restore that golden crunch.

Step-by-step instructions for Grandma's old-fashioned zucchini pie
Here's how to create a rich, creamy zucchini filling with a buttery lattice crust that stays golden and crisp.
Grill and Prepare the Zucchini Filling
Preheat your grill to medium-high heat. Grill the 4 whole medium zucchini for 8-10 minutes per side until they develop grill marks and soften slightly. This step removes excess moisture and adds subtle charred flavor. Transfer the zucchini to a colander and let them cool slightly before gently squeezing out all the liquid. You want the filling to be completely dry—this ensures your pie stays creamy, not soggy.
While the zucchini cools, preheat your oven to 350°F. In a large bowl, combine the grilled zucchini with the 2 cups shredded sharp cheddar cheese, 4 whole large eggs, 0.25 cup granulated sugar, 1.5 teaspoons salt, and 0.5 teaspoon ground black pepper. Mix until the cheese is fully melted and the mixture is smooth. The sugar balances the richness of the cheese, while the spices enhance the natural sweetness of the zucchini. Stir in the 0.5 cup whole milk to create a thick, velvety batter that will form the heart of your pie.
Prepare the Lattice Crust
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 1.5 teaspoons baking powder, and 1.5 teaspoons salt. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Gradually add 0.5 cup ice water (or cold milk if you prefer) until the dough comes together. Wrap the dough in plastic wrap and chill for 30 minutes—this prevents the butter from melting and ensures a flaky texture.
On a lightly floured surface, roll out half of the dough to a 12-inch circle (about 1/8-inch thick). Transfer it to a 9-inch pie dish and trim the edges. Roll out the remaining dough and cut it into 1-inch wide strips. Arrange half the strips horizontally across the pie, spacing them 1/2 inch apart. Fold back every other strip, then weave the remaining strips over and under to create a classic lattice pattern. Brush the lattice with 1 tablespoon extra-virgin olive oil to add shine and flavor. Prick the lattice all over with a fork to allow steam to escape during baking.
Assemble and Bake the Pie
Pour the zucchini filling into the prepared pie crust, spreading it evenly. Sprinkle the 0.25 cup chopped fresh chives over the top for a touch of brightness. Place the pie on a baking sheet lined with parchment paper to catch any drips. Bake for 45-50 minutes until the lattice is deep golden brown and the filling is set but still slightly jiggly in the center. The pie should pull away from the edges of the crust, indicating it's fully baked.
Remove the pie from the oven and let it cool for 15 minutes before serving. The filling will continue to thicken as it cools, becoming even creamier. For best results, serve warm with a side of mixed greens or crusty bread. This pie tastes even better the next day, so consider making it ahead—just reheat in a 350°F oven for 10-15 minutes to restore its warmth.
Pro Tips For Making Grandma'S Old Fashioned Zucchini Pie
- SALT THE ZUCCHINI FIRST: Dump those grated zucchini in a colander and toss with 1 teaspoon of salt—let it sit for 10 minutes while you prep the rest. This pulls out the excess water so your pie filling stays thick and doesn’t turn into soup. I learned this the hard way after my first batch wept like a sad houseplant.
- GRATE CHEDDAR COLD: Skip the pre-shredded bag—use a box of sharp cheddar and grate it yourself while it’s straight from the fridge. Cold cheese melts more evenly in the filling and won’t clump into greasy lumps. (Yes, even if you’re impatient like me.)
- BAKE THE CRUST SEPARATELY: Blind-bake that crust for 8–10 minutes at 375°F before adding the filling—just weigh it down with pie weights or dried beans. This guarantees a crisp base that won’t turn soggy when the wet filling goes in. My grandmother swore by this, and she was right: the difference is noticeable.
- WHISK EGGS UNTIL THICK: Beat those eggs with the flour and milk until the mixture is noticeably thicker—about 2–3 minutes with a whisk. This makes the pie filling set faster and keeps it from curdling when it hits the oven. Sounds weird, but it works: the texture changes from liquid to something that holds its shape.
Pro cooking tips for grandma's old fashioned zucchini pie
Grill for Perfect Texture
Grilling the zucchini first is non-negotiable for the best texture—it removes excess moisture while adding subtle char that deepens the flavor. I use a charcoal grill set to medium-high heat (about 450°F) for 8-10 minutes per side, turning once.
If you don’t have a grill, a cast-iron skillet over medium-high heat works just as well. The key is to get those grid marks—they’re not just for looks, they add a smoky depth that elevates the pie. 🔥
Squeeze Dry Like Your Life Depends On It
After grilling, let the zucchini cool slightly before squeezing. I wrap them in a clean kitchen towel and gently press out every last drop of liquid—this is what keeps your filling light and creamy, not watery.
Some people use a mandoline to grate the zucchini first, but I find grilling and squeezing works better for moisture control. Pro tip: Wear thick gloves—zucchini gets hot after grilling! 💫
Butter Temperature Matters
The secret to a flaky lattice crust lies in keeping the butter cold when mixing. Cut the 1 cup unsalted butter into small cubes and chill them for 15 minutes before adding to the flour.
I use my fingers to work the butter into the flour until it resembles coarse crumbs, then add ice water one tablespoon at a time. If the dough feels too warm, pop it back in the fridge for 10 minutes—this prevents a tough crust. 🧈
Lattice Weaving Tricks
Creating the lattice can feel intimidating, but I’ve got a foolproof method. Roll out the second half of the dough and cut 1-inch strips with a pizza cutter—it’s faster than a knife. Start by placing 3-4 strips horizontally across the pie, spacing them ½ inch apart.
Fold back every other strip, then weave the remaining strips over and under like a basket. Brush with extra-virgin olive oil right before baking for that golden, crisp finish. 🌟
Bake Until Golden, Not Dry
Remove the pie from the oven when the lattice is deep golden brown (not burnt) and the filling is just set—it should still jiggle slightly in the center. Overbaking dries out the filling, so I always check at 45 minutes and tent with foil if needed.
Let it cool for 15 minutes before slicing—this lets the juices redistribute, giving you that perfect creamy texture every time. 💡
Make-Ahead Magic
This pie tastes even better the next day, so I always bake it ahead of time. Store leftovers in an airtight container in the fridge for up to 4 days.
To reheat, cover with foil and warm in a 350°F oven for 10-15 minutes—just until the lattice crisps up again. For freezing, wrap individual slices in plastic wrap and freeze for up to 3 months. Thaw overnight in the fridge before reheating. ❄️

Frequently asked questions
Can I substitute grilled zucchini with raw or sautéed?
Grilled zucchini is key for removing moisture and adding smoky depth, but sautéed works in a pinch. Sauté 4 medium zucchini in a skillet with 1 tbsp olive oil for 5-6 minutes until tender, then cool and squeeze dry. Raw zucchini will make the filling watery—always cook it first!
What if I don’t have a lattice crust mold?
No mold? No problem! Roll out the second dough half and cut 1-inch strips with kitchen scissors or a knife. Weave them over the pie like a basket—fold back every other strip first, then weave the rest over/under. Brush with olive oil for that golden finish.
Why did my filling turn out watery?
Watery filling usually means excess moisture wasn’t removed. Always grill or sauté zucchini first, then squeeze it dry in a clean towel. For extra insurance, let the filling sit for 10 minutes before baking—this helps thicken it.
Can I make this pie ahead of time?
This pie tastes even better the next day. Bake it fully, then store in an airtight container for up to 4 days. Reheat slices in a 350°F oven for 10-15 minutes to restore crispness. Freeze individual slices for up to 3 months.
What’s the best cheese substitute if I don’t have sharp cheddar?
For a similar tang, try pepper jack or Gruyère. If you prefer milder options, Swiss or provolone work well. Just reduce the salt slightly—aged cheeses are saltier. Avoid pre-shredded cheese (it has anti-caking agents that make the filling grainy).
