There’s something incredibly satisfying about a side dish that’s both wholesome and utterly delicious, and this Zucchini and Potato Bake perfectly fits the bill. It’s a comforting casserole that layers tender, thinly sliced zucchini and potatoes with aromatic onions and garlic, all bathed in a creamy sauce and topped with a golden, bubbly cheese crust. This dish is simple to prepare, making it ideal for any weeknight dinner, yet elegant enough to grace your holiday table.
Why I Love This Recipe
As a food writer, I’m always on the hunt for recipes that make vegetables the star without feeling like a compromise. This Zucchini and Potato Bake does just that. What I particularly love about it is the way the thinly sliced potatoes and zucchini absorb the flavors of the sautéed aromatics and the creamy liquid, becoming incredibly tender and flavorful. The combination of mozzarella and Parmesan cheese creates that irresistible golden-brown topping and a gooey, cheesy interior that everyone loves. It’s a wonderful way to utilize abundant summer squash, and it pairs beautifully with almost any main course. It’s pure comfort food that feels surprisingly light.
Ingredients
- 2 medium zucchini, thinly sliced (about ¼-inch thick)
- 2 medium Yukon Gold or russet potatoes, thinly sliced (about ¼-inch thick)
- 1 small onion, thinly sliced
- 2 cloves garlic, minced
- 1 cup shredded mozzarella cheese
- ⅓ cup grated Parmesan cheese
- ½ cup heavy cream or whole milk (heavy cream for richer, more indulgent results)
- 1 tablespoon olive oil or melted butter
- 1 teaspoon dried Italian seasoning
- Salt and black pepper, to taste
- Optional garnish: chopped fresh parsley or chives
Swaps and Notes
- Potatoes: Yukon Gold potatoes offer a creamier texture, while russets will be fluffier. Sweet potatoes could also be used for a slightly different flavor profile. Ensure consistent thin slicing for even cooking.
- Zucchini: Yellow summer squash can be used interchangeably with green zucchini.
- Onion & Garlic: Adjust the amounts to your taste. A shallot could also be used for a milder onion flavor.
- Cheese: Feel free to mix and match cheeses. A blend with Gruyère or provolone could add another layer of flavor.
- Cream/Milk: Heavy cream will yield a richer, thicker sauce. Whole milk will be lighter but still delicious. Lower-fat milks might result in a thinner sauce.
- Herbs: Dried oregano, basil, or a fresh sprig of thyme could replace or supplement the Italian seasoning. Fresh herbs, especially basil, are fantastic for garnish.
- Spice: A pinch of red pepper flakes added with the garlic can give it a subtle kick.
Directions
- Preheat Oven & Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish. This size is perfect for creating nice layers and ensuring even cooking.
- Prepare Vegetables: Thinly slice your zucchini and potatoes. Aim for uniform ¼-inch slices to ensure they cook evenly. A mandoline slicer is excellent for this if you have one, otherwise, a sharp knife and a steady hand will do the trick.
- Sauté Aromatics: In a small skillet, heat the olive oil (or melted butter) over medium heat. Add the thinly sliced onion and sauté for about 3-4 minutes, stirring occasionally, until it has softened and become translucent. Then, toss in the minced garlic and cook for an additional minute until fragrant—ah, that wonderful aroma means flavor is building!
- Layer the Bake (First Pass): Let’s start building those delicious layers! Place half of the thinly sliced potatoes evenly at the bottom of your prepared baking dish. Follow this with half of the thinly sliced zucchini, then spread half of the sautéed onion and garlic mixture over the zucchini. Season this first layer generously with salt, black pepper, and dried Italian seasoning.
- Layer the Bake (Second Pass): Repeat those fabulous layers: add the remaining sliced potatoes, then the remaining zucchini, and finally the rest of the sautéed onion and garlic mix. Season this second layer generously with more salt, black pepper, and Italian seasoning.
- Add Cream & Cheese: Evenly pour the heavy cream or milk over the top of the layered vegetables. Then, sprinkle the shredded mozzarella cheese generously over the cream layer, followed by the grated Parmesan cheese.
- Bake (Covered & Uncovered): Cover the baking dish tightly with aluminum foil. Pop it into the preheated oven and bake for 30 minutes. After 30 minutes, carefully remove the foil. Return the dish to the oven and bake for an additional 15–20 minutes, uncovered, until the top is beautifully golden brown, the cheese is bubbly, and the vegetables are tender when pierced with a fork.
- Rest & Garnish: Give the casserole a little time to rest for about 5 minutes before serving. This allows the creamy sauce to set slightly and makes for easier serving. If you’d like, garnish with fresh chopped parsley or chives for a pop of color and fresh herb flavor!
Tips for Success
- Uniform Slices: This is crucial for even cooking. Thin, consistent slices of potatoes and zucchini will ensure everything cooks through at the same rate.
- Don’t Overcook Onion/Garlic: Sautéing them just until fragrant is enough. They will continue to cook in the oven.
- Season Each Layer: Layering and seasoning each vegetable layer ensures that flavor is distributed throughout the entire casserole, not just on top.
- Covering is Key: Covering the dish for the first part of baking helps steam and tenderize the potatoes and zucchini without drying them out.
- Resting Time: Allowing the casserole to rest for a few minutes after baking helps the cheesy, creamy sauce set up, preventing it from being too runny when served.

Storage and Leftover Tips
Leftover Zucchini and Potato Bake can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can warm individual portions in the microwave, or for best results (to maintain a crispy top if it was there), warm it in a preheated oven at 350°F (175°C) until heated through and bubbly. If reheating in the oven, you can add a fresh sprinkle of cheese for extra melty goodness.
