Method
Prep and preheat
- Preheat your oven to 350°F and grease a 9x13 baking dish so the casserole releases cleanly.
- Spread the prepared dish on a flat rack so it bakes evenly and you can easily monitor bubbling at the edges.
Make the custard mixture
- Whisk the beaten eggs, heavy cream, milk, melted butter, sugar, salt, black pepper, and onion powder together until smooth and well combined.
- Stir in the corn kernels and shredded cheddar cheese until evenly distributed.
Assemble
- Pour the corn mixture into the greased baking dish and spread it out evenly for consistent set and texture.
- Toss the crushed Ritz crackers with the melted butter and scatter evenly over the top so the crust browns deeply.
Bake
- Bake for 40–45 minutes at 350°F until the custard is set, the edges are bubbling, and the cracker topping is deeply golden.
Notes
Pro tip: for the cleanest custard slice, let the scalloped corn stand 5–10 minutes after baking so it thickens as it cools. Refrigerate leftovers in an airtight container up to 3 days; reheat in a 325°F oven until warmed through. Freezing is not recommended because the creamy custard can become grainy after thawing. Dietary swap: use lactose-free milk and lactose-free cheddar if you need lactose reduction (texture may be slightly softer).
