Why Choose This Vegetable Gratin

Traditional gratins often rely on heavy cream and butter, which add richness but also extra calories and saturated fat. This version uses blended cottage cheese and milk to create a creamy sauce that adds protein and calcium without heaviness. Parmesan cheese and olive oil provide flavor and a satisfying texture, so you don’t miss the usual richness.

The spiral arrangement of the vegetables looks impressive but is surprisingly simple to prepare. It’s a great way to serve a colorful, nutritious side dish that feels special without complicated steps.

The Role of Each Vegetable

• White Potato

White potatoes supply energizing carbohydrates, potassium, and vitamin C. They provide a comforting, starchy base that balances the other vegetables.

• Sweet Potato

Sweet potatoes add natural sweetness and beta-carotene, which the body converts into vitamin A. This boosts the dish’s nutritional value and adds a subtle flavor contrast.

• Zucchini

Zucchini contributes fiber, hydration, and extra vitamins and minerals. Its lighter texture and fresh flavor balance the denser potatoes, preventing the gratin from feeling too heavy.

Together, these vegetables create a dish that is colorful, flavorful, and packed with nutrients.

How the Sauce Brings It All Together

The sauce combines cottage cheese, milk, and Parmesan cheese. Blending the cottage cheese creates a smooth, creamy base that coats the vegetables without the need for heavy cream. This adds protein and calcium, making the gratin more filling and nourishing, without adding unhealthy fats and extra calories.

Olive oil adds richness and helps the top brown beautifully in the oven. Parmesan cheese adds a salty, nutty flavor that enhances the overall taste without overpowering the vegetables.

Serves: 6–8

Prep time: 25 minutes

Baking time: 60–75 minutes

Ingredients

• 2 medium white or Yukon Gold potatoes

• 1 large sweet potato, peeled

• 2 medium zucchini

• 1 cup low-fat cottage cheese

• 2 tsp salt, divided

• 2 tsp black pepper, divided

• 2 tsp garlic powder, divided

• 2 tsp Italian seasoning, divided

• 1 tsp sweet paprika

• ½ cup milk

• 1 large egg

• ⅓ cup grated Parmesan cheese, divided

• 1 tablespoon olive oil

• Chopped parsley or additional thyme, for garnish

Directions

1. Preheat the oven to 400°F.

2. Slice the potatoes, sweet potato, and zucchini into approximately ⅛-inch rounds. Keeping the slices similar in thickness will help them cook evenly. A mandoline is helpful, but a sharp knife also works.

3. Place the slices in a single layer on a baking sheet prepared with parchment paper. sprinkle with olive oil and season with paprika, 1 tsp each of salt, pepper, garlic powder and Italian seasoning. Bake for about 15 minutes.

4. Add the cottage cheese, milk, egg, remaining seasonings and half of the Parmesan to a blender or food processor. Blend until mostly smooth.

5. Grease a 9" round baking dish and spread 3 tbsp of the cheese mixture on the bottom.

6. Once vegetables are cool enough to handle, arrange the slices upright around the baking dish, alternating vegetables, in the pattern of your choice.

7. Slowly pour the remainder of the cottage-cheese mixture around and between the vegetables. Drizzle the top with olive oil.

8. Cover the dish tightly with foil and bake for 20-30 minutes. Remove the foil, sprinkle with the remaining Parmesan, and bake for another 20–30 minutes. The gratin is ready when the potatoes are easily pierced with a knife and the top is lightly golden.

9. Allow the gratin to rest for 10–15 minutes before serving. This gives the sauce time to settle and makes the dish easier to portion.

Serving Suggestions
