One such dish is Swiss Chard Gratin, a delicious and comforting recipe that showcases the vibrant and nutritious Swiss chard in a creamy, cheesy sauce. This gratin is a perfect side dish for any meal or a satisfying main course for a light lunch or dinner.

Background and Origin

Gratins are a staple in French cuisine, and their influence extends to Switzerland, particularly in the French-speaking regions. A gratin typically involves baking a dish with a crusty top, often achieved by adding breadcrumbs, cheese, or a combination of both. Swiss Chard Gratin, also known as “Gratin de Blettes” in French, is a popular variation that highlights the versatility and flavor of Swiss chard, a leafy green vegetable rich in vitamins and minerals.


To make a traditional Swiss Chard Gratin, you will need the following ingredients:

For the Swiss Chard:

  • Swiss Chard: 2 large bunches of Swiss chard (about 2 lbs or 900g), stems and leaves separated and chopped.
  • Olive Oil: 2 tablespoons.
  • Garlic: 2 cloves of garlic, minced.
  • Onion: 1 medium onion, finely chopped.
  • Salt: 1 teaspoon.
  • Black Pepper: 1/2 teaspoon.

For the Béchamel Sauce:

  • Butter: 3 tablespoons.
  • Flour: 3 tablespoons.
  • Milk: 2 cups, warmed.
  • Nutmeg: 1/4 teaspoon, freshly grated.
  • Salt: 1/2 teaspoon.
  • Black Pepper: 1/4 teaspoon.

For the Topping:

  • Swiss Cheese: 1 cup of grated Gruyère or Emmental cheese.
  • Breadcrumbs: 1/2 cup.
  • Parmesan Cheese: 1/4 cup of grated Parmesan cheese.
  • Butter: 2 tablespoons, melted.


Step 1: Prepare the Swiss Chard

  1. Separate and Chop: Separate the Swiss chard leaves from the stems. Chop the stems into small pieces and roughly chop the leaves.
  2. Sauté Onions and Stems: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and Swiss chard stems, and sauté for about 5-7 minutes, or until they start to soften.
  3. Add Garlic and Leaves: Add the minced garlic and cook for another 1-2 minutes. Then, add the chopped Swiss chard leaves, salt, and black pepper. Cook until the leaves are wilted and tender, about 5-7 minutes. Remove from heat and set aside.

Step 2: Prepare the Béchamel Sauce

  1. Make the Roux: In a medium saucepan, melt the butter over medium heat. Add the flour and whisk continuously for about 2 minutes to form a roux, which should be smooth and bubbling.
  2. Add Milk: Gradually whisk in the warmed milk, ensuring there are no lumps. Continue to whisk until the sauce thickens and starts to bubble.
  3. Season: Add the freshly grated nutmeg, salt, and black pepper. Stir to combine and remove from heat.

Step 3: Assemble the Gratin

  1. Combine Chard and Sauce: Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the sautéed Swiss chard mixture with the béchamel sauce. Mix well to ensure the chard is evenly coated with the sauce.
  2. Transfer to Baking Dish: Transfer the mixture to a greased baking dish, spreading it out evenly.

Step 4: Prepare the Topping

  1. Mix Topping Ingredients: In a small bowl, combine the grated Gruyère or Emmental cheese, breadcrumbs, grated Parmesan cheese, and melted butter. Mix until well combined.
  2. Add Topping: Sprinkle the topping mixture evenly over the Swiss chard and béchamel in the baking dish.

Step 5: Bake the Gratin

  1. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbly.
  2. Cool Slightly: Remove from the oven and let the gratin cool for a few minutes before serving. This allows the flavors to meld and makes it easier to serve.

Serving Suggestions

  • Accompaniments: Swiss Chard Gratin pairs wonderfully with roasted meats, grilled chicken, or fish. It also complements vegetarian dishes like stuffed mushrooms or roasted vegetables.
  • Wine Pairing: Enjoy this gratin with a crisp white wine such as a Swiss Chasselas or a light Chardonnay to balance the richness of the dish.
  • Garnishes: For added flavor and color, garnish the gratin with fresh chopped parsley or chives before serving.

  • Additions: Enhance the gratin with additional ingredients like sautéed mushrooms, diced ham, or crispy bacon for added texture and flavor.
  • Herb Variations: Incorporate fresh herbs like thyme, rosemary, or sage into the béchamel sauce for an aromatic twist.
