Ingredients
• 2 medium zucchini, sliced thinly
• Salt, for drawing out moisture
• 500 g potatoes (about 17.6 oz), peeled and thinly sliced
• 150 g (5.3 oz) grated cheese, divided (cheddar, mozzarella, or blend)
• 2 Tbsp butter
• 2 Tbsp all-purpose flour
• 500 ml (2 cups) milk
• 1 tsp salt
• ½ tsp ground nutmeg
• Olive oil, for greasing
Step-by-Step Cooking Directions
-
Prep the zucchini by salting liberally and letting it sit 10 minutes to expel water; gently press to drain.
-
Slice potatoes into 2–3 mm rounds; blanch in boiling salted water for 7 minutes until just tender; drain.
-
Preheat oven to 375 °F (190 °C); grease a baking dish with olive oil or butter.
-
In a saucepan over medium heat, melt butter. Whisk in flour to create a roux; cook 1–2 minutes.
-
Gradually whisk in milk, stirring to prevent lumps. Add salt and nutmeg; simmer until thick enough to coat a spoon. Remove from heat.
-
Layer half the potatoes in the dish; pour one-third of the sauce over them; sprinkle with half the cheese.
-
Arrange zucchini slices in an even layer; pour another third of the sauce; top with remaining potatoes, remaining sauce, and remaining cheese.
-
Bake 25–30 minutes until the top is golden and bubbly. Let rest 5 minutes before slicing.

The Origins and Popularity of the Recipe
Gratinated vegetable dishes date back to 18th-century French cuisine, epitomized by Gratin Dauphinois—thin potatoes baked in cream with garlic. In North America, home cooks adapted the gratin technique to include local produce, giving rise to versions layered with summer squash, zucchini, and cheese. Its ease of assembly and crowd-pleasing appeal made it a staple in community cookbooks and church potlucks. Today, the Cheesy Zucchini and Potato Bake enjoys renewed popularity on social media, praised for its vibrant layers, ease of preparation, and adaptability to gluten-free or dairy-free diets.
