Ingredients
- 2 lbs zucchini
- 2 lbs Yukon Gold potatoes (small, similar in diameter to zucchini)
- 1 tsp sea salt
- 1/2 tsp black pepper, divided
- 1/2 tsp dried oregano
- 2 cups heavy whipping cream
- 1 1/2 cups shredded Parmesan cheese (low fat), divided
- 2 garlic cloves, minced
- 2 Tbsp chopped chives or green onions, plus extra for garnish
Instructions
- Prepare the Cream Mixture: In a medium bowl, combine the heavy whipping cream, 1 cup of Parmesan cheese, minced garlic, and chopped chives. Stir well and set aside.
- Slice the Vegetables: Thinly slice the zucchini into 1/4-inch thick rounds. Slice the potatoes very thinly (1/16-inch thick) to ensure even cooking. Transfer both to a large mixing bowl and season with sea salt, black pepper, and oregano.
- Assemble the Dish: In a greased 9×13-inch casserole dish, layer the zucchini and potatoes, alternating them. Since there will be more potato slices, double up on them as needed.
- Add the Cream Mixture: Evenly pour the prepared cream mixture over the layered vegetables. Sprinkle the remaining 1/2 cup of Parmesan cheese over the top.
- Bake: Place the dish in a preheated 400˚F oven and bake uncovered for 40-45 minutes, or until the potatoes are tender and can be easily pierced with a fork.
- Rest and Serve: Remove from the oven and let it rest for at least 10 minutes before serving. Garnish with additional chives if desired.
Tips
- Even Cooking: Cutting the potatoes very thin ensures they cook evenly with the zucchini.
- Cheese Choices: For extra flavor, try mixing in some shredded mozzarella or Gruyère with the Parmesan.
- Prevent Sogginess: If your zucchini releases too much water, lightly salt and drain them on paper towels before layering.
- Cream Alternative: Half-and-half can be used for a lighter version.

Variations and Substitutions
- Different Vegetables: Swap zucchini for yellow squash or eggplant for a twist.
- Herb Options: Fresh basil or thyme can replace oregano for a different flavor profile.
- Protein Boost: Add cooked, crumbled bacon or shredded rotisserie chicken for extra heartiness.
- Dairy-Free: Substitute heavy cream with coconut cream and use nutritional yeast instead of Parmesan.
