Ingredients
Method
- Preheat oven to 375°F (190°C). Sauté onion in butter for 5 minutes, then add garlic, zucchini, and corn; cook 3 to 4 minutes. Transfer to a greased 2-quart baking dish.
- Whisk cream, eggs, cheddar, thyme, salt, and pepper until smooth.
- Pour custard over vegetables and stir gently to distribute.
- Mix panko, melted butter, and Parmesan; sprinkle over the top.
- Bake 35 to 40 minutes until bubbling and golden. Rest 5 minutes before serving.
Notes
Let the casserole rest for at least 5 minutes after baking so the custard firms up enough to scoop cleanly. If your baking dish is deeper than 2 inches, you may need an extra 5 to 8 minutes of bake time.
