When you think of "au gratin," chances are you're imagining a potato dish. And that makes sense! Usually, this French classic involves loads and loads of potatoes, cheese, and breadcrumbs. So, we've taken that model and recreated a lightened-up version, which led to this recipe for Swiss chard au gratin. You might be able to guess from the recipe title that we've swapped in Swiss chard instead of potatoes, so it will be less dense and more earthy! You also have several tasty options: Swap spinach for the chard, use paprika or Dijon mustard instead of nutmeg, or look for rainbow chard for a bright-colored, fun spin on this recipe.


Uncooked Swiss chard

1½ pound(s), stems trimmed, chopped

Olive oil

1 Tbsp

All-purpose flour

1 Tbsp

Low-fat milk

1 cup(s), at room temperature

Uncooked onion(s)

½ small, minced

Ground nutmeg

tsp, optional

Grated Parmesan cheese

½ cup(s), Parmigianno-Reggiano recommended

Dijon Mustard

½ tsp

Table salt

tsp, or to taste

Black pepper

tsp, or to taste


  1. Steam, parboil or microwave chard until wilted, about 2 to 3 minutes; drain and place in a serving dish.
  2. Place a medium-size saucepan over medium-low heat; add oil. When oil begins to shimmer, add flour, whisking constantly for 3 minutes. Slowly whisk in milk, making sure to scrape bottom of pan.
  3. Add onion and nutmeg; simmer gently, stirring often, until mixture starts to thicken.
  4. Remove pan from heat; stir in cheese. Season to taste with salt and pepper; stir until well-combined. Pour sauce over chard; toss and serve. Yields about 1/2 cup per serving.
