- 2½–3 cups zucchini, grated and thoroughly drained (about 2 medium zucchini)
- 1 (8.5 oz) box cornbread/muffin mix (like Jiffy)
- 1 cup shredded sharp cheddar cheese (optional but highly recommended)
- ½ cup sour cream or plain Greek yogurt
- ½ cup milk (dairy or unsweetened plant-based)
- 2 large eggs, room temperature
- ¼ cup melted butter or oil
- ½ tsp garlic powder
- ½ tsp onion powder
- ½ tsp salt
- ¼ tsp black pepper
For the Topping (Optional):
- ¼ cup shredded cheddar
- 1 tbsp melted butter
- Pinch of paprika or cayenne
🥒 Zucchini tip: Squeeze grated zucchini in a clean kitchen towel—excess moisture = soggy casserole!
Step-by-Step Instructions
1. Prep the Zucchini
Grate zucchini (peeled or unpeeled—your choice!). Place in a colander, sprinkle with a pinch of salt, and let sit 10 minutes. Then squeeze out as much liquid as possible using a towel.
2. Make the Batter
Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
In a large bowl, whisk cornbread mix, sour cream, milk, eggs, melted butter, garlic powder, onion powder, salt, and pepper until smooth.
Fold in drained zucchini and 1 cup cheese (if using).
3. Bake to Golden Perfection
Pour into the baking dish.
For extra crunch, top with ¼ cup cheese, drizzle with 1 tbsp melted butter, and sprinkle with paprika.
Bake for 35–40 minutes, until golden and a toothpick comes out clean.
Let rest 10 minutes before serving.
Tips for Casserole Success
- Dry zucchini is non-negotiable—this is the #1 secret to a firm, not mushy, casserole.
- Use room-temperature eggs—they blend smoother and add lift.
- Don’t skip the sour cream—it adds moisture and tang to balance the cornbread’s sweetness.
- Make it ahead: Assemble unbaked, cover, and refrigerate for up to 24 hours. Add 5–10 minutes to bake time.
- Double the zucchini if you’re feeling generous—just squeeze extra dry!
Delicious Variations
- Mexican-Style: Add 1 cup corn, ½ cup black beans, and 1 tsp cumin
- Herb Garden: Mix in 2 tbsp fresh basil, thyme, or chives
- Spicy Kick: Stir in 1 diced jalapeño or ½ tsp cayenne
- Gluten-Free: Use GF cornbread mix (like Krusteaz)
- Vegan: Use flax eggs, plant-based milk/yogurt, and dairy-free cheese
Serving Suggestions
- Classic: With grilled chicken, burgers, or BBQ ribs
- Vegetarian feast: Alongside black-eyed peas and collard greens
- Brunch side: Next to scrambled eggs and bacon
- Potluck star: Cut into squares and serve with a dollop of sour cream
