This savory sweet corn zucchini pie transforms summer's bounty into a delicious meal that's both comforting and fresh. The combination of sweet corn kernels, tender zucchini, and earthy mushrooms creates a vegetable-packed dish that's substantial enough for dinner yet light enough for lunch.
I created this recipe during a particularly productive garden season when zucchini was taking over my kitchen. Now it's become our go to solution for using summer produce before it goes to waste.
Ingredients
- Butter provides the rich foundation for sautéing and adds wonderful flavor to the vegetables
- Yellow onion creates an aromatic base that sweetens as it cooks
- Sweet corn kernels bring natural sweetness and juicy pops of flavor use fresh summer corn when possible
- Zucchini contributes moisture and a tender texture slice them thin for quicker cooking
- Mushrooms add savory umami depth and meaty texture cremini work particularly well
- Dried basil and oregano infuse classic Italian flavors that complement the vegetables
- Salt enhances all the flavors and balances the natural sweetness of the corn
- Cheese blend creates the creamy binding texture using both mozzarella and Swiss gives the perfect melt and flavor
- Eggs provide structure and richness allowing the pie to set up properly
Step-by-Step Instructions
- Prepare Your Pan
- Preheat your oven to 375°F and thoroughly grease a 9 inch pie dish. Be generous with the greasing as this helps achieve clean slices when serving.
- Sauté Aromatics
- Melt the butter in a large skillet until it begins to foam. Add the diced onion and cook over medium heat until they become translucent and aromatic about 3 minutes. Avoid browning them too quickly as you want them sweet not bitter.
- Cook Mushrooms
- Add your sliced mushrooms to the onions and continue cooking. Watch as they release their moisture and begin to shrink and brown around the edges. This process takes 3 to 4 minutes and builds wonderful flavor through caramelization.
- Add Vegetables
- Introduce the corn kernels and thinly sliced zucchini to the skillet. Sprinkle in the dried herbs and salt evenly across the mixture. Cook for a full 6 to 8 minutes stirring occasionally to ensure even cooking. The zucchini should become tender but not mushy and most of the liquid should evaporate to prevent a soggy pie.
- Cool Mixture
- Remove your skillet from heat and allow the vegetable mixture to cool slightly. This prevents the eggs from scrambling when combined and makes handling easier.
- Combine Filling
- In a large bowl whisk eggs until well beaten then fold in the shredded cheese ensuring even distribution. Add your slightly cooled vegetable mixture and gently fold everything together until thoroughly combined.
- Bake Pie
- Pour the entire mixture into your prepared pie dish spreading it evenly to the edges. Place in the preheated oven and bake for 30 to 35 minutes until the center is set and the top develops an appetizing golden color.
- Rest Before Serving
- Allow the finished pie to rest for at least 10 minutes before slicing. This resting period is crucial for the pie to fully set and makes for cleaner more attractive slices.

The secret to this pie's incredible flavor is allowing the vegetables to caramelize properly before combining with the eggs and cheese. I learned this technique from my grandmother who always said that patience in the pan pays off on the plate. Her wisdom rings true every time I make this dish.
Make Ahead Options
This zucchini pie is perfect for meal prep. You can prepare the entire vegetable mixture up to two days ahead and store it in the refrigerator. When ready to bake simply bring it to room temperature combine with the egg and cheese mixture and proceed with baking. The finished pie also freezes remarkably well. Cut into individual portions freeze on a baking sheet until solid then transfer to freezer bags for easy single servings that can be reheated in the microwave.
Seasonal Adaptations
While summer provides the ideal ingredients for this recipe it can be enjoyed year round with simple adaptations. In winter substitute frozen corn kernels thawed and patted dry. You can also experiment with different seasonal vegetables such as bell peppers in late summer or butternut squash in fall. The basic egg and cheese base works beautifully with nearly any vegetable combination making this a versatile recipe for your cooking repertoire.
Serving Suggestions
This zucchini corn pie works wonderfully as the centerpiece of a light meal served with a simple green salad dressed with lemon vinaigrette. For brunch pair it with fresh fruit and yogurt. If serving for dinner consider adding a protein side like grilled chicken or fish. A dollop of crème fraîche or sour cream on top adds a lovely tangy contrast to the savory pie especially when garnished with fresh herbs like chives or basil.
