Step-by-Step Instructions

1. Prep the Zucchini (Critical Step!)

Shred zucchini using a box grater or food processor.

Place in a colander; toss with 1 tsp salt. Let sit 10 minutes.

Squeeze aggressively in a clean kitchen towel until no more liquid drips out (~½ cup liquid removed). Set aside.

2. Mix Dry Ingredients

Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish.

In a large bowl, whisk:

→ Cornmeal

→ Flour

→ Sugar

→ Baking powder + baking soda + salt

3. Mix Wet Ingredients

In another bowl, whisk:

→ Buttermilk

→ Sour cream/yogurt

→ Melted butter/oil

→ Eggs (beaten first)

4. Combine & Fold

Pour wet ingredients into dry; stir until just combined (lumps are fine!).

Fold in:

→ Squeezed zucchini

→ Corn kernels

→ Cheese + green onions (if using)

5. Bake Until Golden

Pour batter into prepared dish; spread evenly.

Bake 25–30 minutes until golden brown and a toothpick inserted in the center comes out clean.

✨ Edges should pull slightly from the pan.

6. Cool & Serve

Let rest 10 minutes before slicing (holds together better).

Serve warm with butter, honey, or alongside chili, BBQ, or roasted chicken.

🌽 Optional topping: Brush with melted butter + sprinkle with extra cornmeal before baking for crunch.

Serving Suggestions

Brunch star: Top with a fried egg and hot sauce

Pro Tips for Success

SQUEEZE THE ZUCCHINI—this is the #1 reason casseroles turn out soggy.

Don't overmix—stir until just combined for tender crumb.

Add corn—the pops of sweetness balance zucchini's mildness perfectly.

Make it ahead: Assemble unbaked; refrigerate overnight. Add 5 mins to bake time.

FAQs: Your Questions, Answered

Q: Can I use yellow squash?

A: Yes! Or a mix of zucchini + yellow squash.

Q: Why is my casserole dense/gummy?

A: Overmixed batter or under-baked. Mix gently and bake until toothpick is clean.

Q: Can I make this gluten-free?

A: Yes! Use 1:1 GF flour blend + certified GF cornmeal.

Q: How do I store leftovers?

A: 3 days covered at room temp; 5 days refrigerated. Reheat in oven or toaster oven (microwave makes it soggy).

Vegan Version

Replace eggs with 2 tbsp ground flaxseed + 6 tbsp water (let sit 5 mins)

Use plant-based butter + unsweetened almond milk + 1 tbsp vinegar for buttermilk

Skip cheese or use vegan shreds
