Yield
Serves 6 generous portions
Difficulty Level
Easy – Perfect for cooks of all skill levels
Ingredients
- 3 medium zucchinis, thinly sliced
- 1 cup shredded sharp Cheddar cheese
- 1 cup shredded Gruyère cheese, for a rich, nutty flavour
- ½ cup freshly grated Parmesan cheese (plus extra for topping)
- 1 cup whole milk
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- Salt and freshly cracked black pepper to taste
- ½ teaspoon smoked paprika
- ¼ teaspoon nutmeg (optional, for depth)
- Fresh thyme sprigs for garnish
- ½ cup panko breadcrumbs (optional, for an extra crunchy topping)

Instructions
- Prepare the zucchini: After washing, slice zucchinis into uniform thin rounds, about ¼ inch thick. Lay them on paper towels to absorb excess moisture. This step ensures your casserole isn’t watery but delightfully creamy.
- make the cheese sauce: In a medium saucepan, melt butter over medium heat. Sauté the finely chopped onion and minced garlic for 3-4 minutes until translucent and fragrant, stirring frequently.
- Whisk in flour: Sprinkle in the all-purpose flour, stirring constantly to form a smooth roux. Cook for 1-2 minutes, until golden but not browned, to avoid any raw flour taste.
- Gradually add milk: Slowly pour in whole milk, whisking continuously to prevent lumps. Continue to cook and whisk until the sauce thickens and coats the back of a spoon, about 5-6 minutes.
- Add cheeses: Remove the sauce from heat and stir in shredded Cheddar, Gruyère, and Parmesan. Season with salt, pepper, smoked paprika, and nutmeg. Stir until the cheeses melt wholly into a silky, luscious sauce.
- Assemble the casserole: In a buttered baking dish, layer half of the zucchini slices evenly. Pour half of the cheese sauce over the zucchini. Repeat with remaining zucchini and cheese sauce, ensuring even coverage.
- Add the topping: In a small bowl, mix panko breadcrumbs with a tablespoon of parmesan. Sprinkle this mixture evenly over the top to create a crunchy golden crust.
- Bake: Place the casserole in a preheated oven at 375°F (190°C). Bake uncovered for 35-40 minutes or until the top is bubbling and beautifully golden brown.
- Rest before serving: Remove from the oven and let the casserole rest for 5 minutes. This resting time allows the layers to set, making serving easier and maintaining that perfect melt-in-your-mouth texture.
Tips for Customizing Your Golden Cheesy Zucchini Casserole Bake

Adding your own twist is one of the joys of this dish. Swap Gruyère for Fontina for a creamier melt or add crumbled feta for tangy bursts.For a gluten-free variation, replace all-purpose flour with cornstarch in the sauce and omit panko or use gluten-free breadcrumbs.To introduce a protein element, stir in cooked, crumbled Italian sausage or roasted chicken before baking. Fresh herbs like basil or oregano can amplify the freshness of zucchini, while a dash of cayenne pepper spices things up for adventurous palates.Don’t hesitate to adjust seasoning gradually-balancing the rich cheese with the mild zucchini is key.
Chef’s Notes
- Zucchini Prep: Salt sliced zucchini lightly and let sit for 10 minutes, then pat dry to remove excess moisture and prevent a watery casserole.
- Cheese Selection: Use freshly shredded cheese rather than pre-shredded for better melt and flavor.
- Make-Ahead: Assemble the casserole and refrigerate up to 24 hours before baking. Add extra baking time if chilled.
- Storage: Leftovers store well in the fridge for 3 days and reheat beautifully in the oven or microwave.
