What is Flan Provençal?

Flan? But wait, isn’t that a sweet, wobbly caramel dessert? You’re not wrong! But have you ever known the French to make things simple? This is where the beautiful confusion begins. In France, “flan” can refer to both sweet and savory tarts or custards. Our Flan Provençal is firmly in the savory camp, more like a crustless quiche or a baked frittata. Think of it as the original flan’s sophisticated, worldly cousin who summers in the Mediterranean. They say the way to a person’s heart is through their stomach, and this dish is a delightful surprise that wins everyone over. Ready to solve this delicious mystery for yourself? Let’s get cooking!

Why You’ll Love This Flan Provençal

This recipe is a staple in my home for so many reasons, and I know it will become one in yours too. Here’s why you’ll fall head over heels for this simple French classic:

• A Taste of the Mediterranean Sun: The absolute highlight of this dish is its flavor. Each bite is a journey to the South of France. The sweetness of slow-cooked onions and ripe tomatoes, the earthy notes of zucchini, and the fragrant bouquet of Herbes de Provence are all brought together by a rich, creamy egg custard. The top bakes to a beautiful golden-brown, while the inside remains tender and luscious. It’s pure comfort food that tastes light and sophisticated.
• Budget-Friendly & Beautiful: Who says elegant food has to be expensive? This Flan Provençal is a champion of frugality. It uses humble, inexpensive summer vegetables like zucchini and tomatoes. It’s the perfect recipe for using up that last bit of produce in your crisper drawer. Making this at home costs a fraction of what you’d pay for a similar dish at a café, proving that a five-star meal can be achieved on a one-star budget.
• The Magic is in the Herbs (and Cheese!): What makes this dish truly special are the quintessential Provençal ingredients. A generous sprinkle of Herbes de Provence (a blend of thyme, rosemary, savory, and oregano) infuses the entire flan with its signature aroma. For the cheese, I use Gruyère for its nutty, salty flavor that melts beautifully, but as you’ll see in my tips, you can easily swap it. It’s a simple combination that, much like in my Rustic Vegetable Tart, proves that great ingredients need little fuss. Give it a try and see just how simple delicious can be!

Key Ingredients for Flan Provençal

Here are the simple, fresh ingredients you’ll need. The beauty of this recipe lies in its quality produce, so use the best you can find!

• 1 tbsp Olive Oil
• 1 Large Yellow Onion, finely chopped
• 2 Cloves Garlic, minced
• 2 Medium Zucchini (about 500g or 1 lb), thinly sliced
• 2 Large Roma Tomatoes, sliced
• 4 Large Eggs
• 1 cup (240ml) Heavy Cream (or half-and-half)
• 1 cup (100g) Gruyère Cheese, grated (plus extra for topping)
• 1 tsp Herbes de Provence
• 1/2 tsp Salt (or to taste)
• 1/4 tsp Black Pepper, freshly ground

Step-by-Step Instructions

1. Preheat and Prepare: First things first, preheat your oven to 180∘C (350∘F). Generously grease a 9-inch (23cm) pie dish or a similar-sized baking dish with butter or olive oil.
2. Sauté the Vegetables: Heat the olive oil in a large skillet or frying pan over medium heat. Add the chopped onion and cook for 5-7 minutes, until softened and translucent. Add the minced garlic and cook for another minute until fragrant.
3. Cook Down the Zucchini: Add the sliced zucchini to the skillet. Cook for about 8-10 minutes, stirring occasionally, until the zucchini is tender and has released most of its water. This step is crucial to prevent a watery flan!
4. Create the Custard Base: While the vegetables are cooking, grab a large bowl. Crack in the 4 large eggs and whisk them until they are light and frothy. Pour in the heavy cream, and whisk again to combine everything smoothly.
5. Season and Combine: To the egg mixture, add the grated Gruyère cheese, Herbes de Provence, salt, and freshly ground black pepper. Give it one final whisk to ensure everything is well incorporated.
6. Assemble the Flan: Once the zucchini is tender, remove it from the heat. Carefully spoon the cooked vegetable mixture into your prepared baking dish, spreading it out evenly. Arrange the sliced Roma tomatoes over the top of the zucchini.
7. Pour and Bake: Gently pour the egg and cheese mixture over the vegetables in the baking dish. Tilt the dish slightly to make sure the custard fills in all the gaps. Sprinkle a little extra grated Gruyère on top for a beautiful golden crust.
8. Bake to Perfection: Place the dish in the preheated oven and bake for 40-45 minutes. The Flan Provençal is ready when the center is just set (it should have a very slight jiggle) and the top is golden brown and puffed up.
9. Rest and Serve: Let the flan rest for at least 10 minutes before slicing and serving. This allows it to set properly and makes for cleaner slices. It tastes wonderful warm or at room temperature.

What to Serve Flan Provençal With

This versatile dish pairs beautifully with a variety of sides. Here are a few of my favorite combinations:

• Simple Green Salad: A crisp salad with a classic French vinaigrette is the perfect fresh counterpoint to the rich flan.
• Crusty Baguette: Essential for soaking up every last bit of flavor! A warm, crusty loaf of French bread is non-negotiable in my house.
• Chilled Rosé Wine: To complete the Provençal experience, serve it with a glass of dry, chilled rosé wine.
• Grilled Meats: For a heartier meal, the flan works beautifully as a side dish to grilled chicken, fish, or even a simple steak.

Top Tips for Perfecting Flan Provençal

• Don’t Skip Sautéing! The most common mistake is not cooking the water out of the vegetables, especially zucchini. Taking the time to sauté them properly ensures your flan is creamy and custardy, not watery.
• Cheese Variations: While Gruyère is classic, feel free to experiment! Crumbled feta or goat cheese would add a tangy kick. A sharp cheddar or Parmesan would also be delicious.
• Herb Power: If you don’t have Herbes de Provence, you can make your own blend with dried thyme, rosemary, and oregano. Fresh, finely chopped basil or parsley stirred into the custard at the end is also a wonderful addition.
• Make-Ahead Tip: You can sauté the vegetables a day in advance and store them in the refrigerator. When you’re ready to bake, just assemble with the custard and pop it in the oven for a super-fast meal.

Storing and Reheating Tips

• Storing: Allow the Flan Provençal to cool completely to room temperature. Cover the dish tightly with plastic wrap or transfer leftovers to an airtight container. It will stay fresh in the refrigerator for up to 4 days.
• Freezing: I generally don’t recommend freezing egg-based custards as the texture can become a bit spongy upon thawing. However, if you must, wrap individual slices tightly in plastic wrap and then foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
• Reheating: For the best results, reheat slices in an oven or toaster oven at 160∘C (325∘F) for 10-15 minutes, or until warmed through. This helps the top get a little crisp again. You can use a microwave in a pinch, but be careful not to overdo it, as it can make the eggs rubbery.

FAQs about Flan Provençal

1. What is the exact difference between Flan Provençal, a frittata, and a quiche? This is a fantastic question as they are all very similar! The main difference lies in the crust and the cooking method. A quiche traditionally has a pastry crust. A frittata is an Italian dish that typically starts cooking on the stovetop and is then finished in the oven or under the broiler, and it contains less dairy, making it firmer.

Our Flan Provençal is crustless (like a frittata) but contains a higher ratio of cream or milk to eggs (like a quiche), which is baked entirely in the oven. This high dairy content is what gives it that signature light, soft, and incredibly creamy custard texture that sets it apart. It’s the most delicate of the three.

2. Can I make this Flan Provençal dairy-free? Absolutely! To make a dairy-free version, you can easily substitute the heavy cream with a full-fat, unsweetened plant-based alternative. Canned coconut cream would give a rich result, or a good quality soy or oat cream would also work well. For the cheese, use your favorite brand of dairy-free shredded cheese that melts well. The flavor profile will change slightly, but it will still be incredibly delicious.

3. Why did my flan turn out watery? The most likely culprit is vegetable moisture. Vegetables, especially zucchini and tomatoes, release a lot of water when they cook. It is absolutely essential to follow step 3 and sauté the zucchini until it is tender and the excess liquid has evaporated from the pan. If you add watery vegetables to the egg custard, that water will seep out during baking and prevent the flan from setting properly, resulting in a soggy bottom and a watery texture. Take your time with this step; it’s the key to a perfect, creamy consistency.

4. Can I add other vegetables or proteins to this recipe? Yes, this recipe is incredibly versatile! Think of it as a base for your creativity. Sautéed mushrooms, bell peppers, spinach (be sure to squeeze it dry!), or asparagus would all be wonderful additions. Just make sure to cook them first to release their moisture. For a protein boost, you can add cooked, crumbled bacon or sausage, diced ham, shredded chicken, or even some canned tuna (drained well). Just fold your chosen additions into the vegetable base before pouring over the custard.
