Ingredients
Base Ingredients
200 g feta cheese, crumbled
200 ml crème fraîche or heavy cream
2 tablespoons olive oil
Vegetables
3 medium potatoes, peeled and thinly sliced
2 carrots, peeled and thinly sliced
1 zucchini, washed and sliced
1 medium onion, thinly sliced
1 clove garlic, minced or finely chopped
Seasonings & Herbs
1–2 teaspoons Herbs de Provence, or a blend of dried thyme, rosemary, and oregano
Salt, to taste
Freshly cracked black pepper, to taste
Instructions
Prepare the Vegetables
Preheat the oven to 375°F (190°C).
Peel the potatoes and carrots, then slice them thinly and evenly. Thin slices are important because they allow the vegetables to cook at the same rate and create tender layers throughout the gratin.
Slice the zucchini and onion. Mince the garlic finely.
If the potato slices feel very starchy or wet, gently pat them dry with a clean kitchen towel. This helps prevent the gratin from becoming overly watery.
Prepare the Creamy Feta Mixture
Place the crème fraîche or heavy cream in a bowl. Add about half of the crumbled feta, the minced garlic, Herbs de Provence, a small pinch of salt, and freshly cracked black pepper.
Stir gently until the ingredients are well combined.
Reserve the remaining feta for the top of the gratin. Keeping some feta aside allows it to form a flavorful golden topping during baking.
Layer the Vegetables
Lightly grease a medium-sized baking dish with a little olive oil.
Arrange a layer of potato slices across the bottom of the dish. Add some carrots, zucchini, and onion over the potatoes.
Season lightly with black pepper and a small amount of salt. Be careful with the salt because feta is naturally salty.
Continue layering the remaining vegetables, trying to distribute them evenly throughout the dish.
Add the Cream and Feta
Pour the creamy feta mixture evenly over the layered vegetables. Gently spread it with the back of a spoon so that it reaches as many areas as possible.
Drizzle the remaining olive oil over the top.
Finish by scattering the remaining crumbled feta evenly across the surface.
Bake the Gratin
Cover the baking dish loosely with aluminum foil and place it in the preheated oven.
Bake for approximately 40 minutes. The foil helps the vegetables soften without allowing the top to brown too quickly.
Remove the foil and continue baking for another 15–25 minutes, or until the potatoes and carrots are completely tender and the top is lightly golden.
To check for doneness, insert a thin knife into the center. It should slide easily through the vegetables.
If the top needs additional browning, place the gratin under the broiler for 1–2 minutes at the end, watching carefully to prevent burning.
Rest and Serve
Remove the gratin from the oven and allow it to rest for about 10 minutes before serving.
This short resting period allows the creamy mixture to settle slightly and makes the gratin easier to portion.
Serve warm as a side dish with roasted chicken, grilled fish, baked meat, or a fresh Mediterranean salad.
Tips
Slice the Vegetables Evenly
Try to keep the potatoes and carrots thin and similar in thickness. If some pieces are much thicker than others, the thinner vegetables may become soft before the thicker pieces are fully cooked.
Choose the Right Baking Dish
A medium-depth baking dish works well for this recipe. Avoid using a dish that is extremely deep because the center may take much longer to cook.
Do Not Over-Salt
Feta provides plenty of salty flavor. Season the vegetables lightly and taste the cream mixture before adding additional salt.
Use Heavy Cream for Extra Richness
Crème fraîche gives the gratin a slightly tangy and luxurious flavor, while heavy cream creates a smoother and richer texture. Either works well.
Do Not Skip the Resting Time
Letting the gratin rest after baking gives the creamy sauce time to thicken slightly. Cutting into it immediately may cause more of the sauce to run to the bottom of the dish.
Check the Potatoes First
Potatoes are usually the best indicator of doneness. If a knife slides easily through the center potato slices, the other vegetables should generally be tender as well.
Watch the Final Browning
Feta can brown quickly under high heat. If using the broiler, stay close to the oven and remove the dish as soon as the top reaches the desired golden color.
Make It Ahead
The gratin can be assembled several hours before baking and kept covered in the refrigerator. Allow the dish to sit at room temperature briefly before placing it in the oven, then bake until completely hot and tender.
Variations
Add Mushrooms
Sliced mushrooms can be added between the vegetable layers for a deeper earthy flavor and extra texture.
Add Bell Peppers
Red or yellow bell peppers can add sweetness, color, and a slightly smoky Mediterranean character to the gratin.
Add Spinach
A handful of fresh spinach can be layered between the vegetables. It will wilt as the gratin bakes and adds extra greens to the dish.
Add Tomatoes
Thinly sliced tomatoes can be included for a brighter, more summery Mediterranean variation. Pat them lightly dry first to reduce excess moisture.
Add Parmesan
For a more deeply browned topping, sprinkle a small amount of Parmesan over the feta before baking.
Use Different Herbs
Instead of Herbs de Provence, try dried oregano, thyme, rosemary, basil, or a combination of your favorite Mediterranean herbs.
Make It More Garlicky
If you enjoy a stronger garlic flavor, increase the garlic slightly or add a small amount of roasted garlic to the cream mixture.
Q&A
Can I use heavy cream instead of crème fraîche?
Yes. Heavy cream works very well and creates a smooth, rich sauce. Crème fraîche adds a slightly tangy flavor.
Can I prepare this gratin ahead of time?
Yes. Assemble the gratin several hours ahead, cover it, and refrigerate it until ready to bake. Allow it to warm slightly before baking.
Why are my potatoes still firm?
The potato slices may be too thick, or the baking dish may be too deep. Slice the potatoes thinly and evenly, and make sure the dish is covered during the first stage of baking.
Can I use different vegetables?
Absolutely. Mushrooms, bell peppers, spinach, tomatoes, or other seasonal vegetables can be incorporated while keeping the same creamy feta base.
How do I store leftovers?
Allow the gratin to cool, then cover and refrigerate. Store leftovers for up to 3 days and reheat gently in the oven or microwave.
Can I freeze vegetable gratin?
It can be frozen, although the texture of the zucchini and cream sauce may change slightly after thawing. For the best texture, enjoy it fresh or refrigerated.
What should I serve with this gratin?
It pairs well with grilled or roasted chicken, fish, lamb, beef, or a simple green salad. It can also be served as a vegetarian main dish with crusty bread and additional salad.
