Years ago I made this interesting Swiss Chard Casserole recipe that intrigued me partly because of the addition of a little soy sauce to the egg mixture, which gave it lots of great Umami flavor. And then I started growing Swiss Chard in my garden and kept making this recipe, adapting it in lots of different ways through the years!

Early on I replaced the breadcrumbs with hemp seeds, which made it a low-carb and gluten-free recipe, and I even went through a phase of cooking it in a mini loaf pan (see below). And for quite a few years I’ve been making it with a little grated Parmesan added to the top of the casserole before it goes in the oven.

I’m a fan of Swiss Chard in the garden for the way you can cut it and it keeps growing back all summer, and this Swiss Chard Casserole is good for breakfast, lunch, or dinner and it came to be one of my favorite ways to cook Swiss Chard. This year I didn’t grow any chard, but when I saw some at the store recently I decided this recipe needed better photos!

What is Swiss Chard?

Swiss Chard is a type of greens that’s one of The World’s Healthiest foods, containing significant nutrients with impressive health benefits. It has many other names, including Chard, Silverbeet, Perpetual Spinach, or Mangold. Chard has shiny green leaves, with stems that can be a variety of colors, and I’m fond of a variety called Rainbow Chard, with mixed stem colors in the same pack of seeds. Chard is one of the easiest greens to grow, and it’s also very versatile in cooking, and well worth adding to your vegetable shopping list if you haven’t tried it.

Can you use other leafy greens in this recipe?

I’ve loved this casserole with Swiss Chard, but of course you can use other leafy greens like kale, collards, spinach, or even Bok Choy or turnip greens in this veggie casserole.

This Swiss Chard Casserole is probably the type of dish that will never be too photogenic, but I did like my experiments with cooking it in a Mini Loaf Pan (affiliate link) for more defined portions. I like to eat these with a dollop of sour cream, as you can tell from the photo.

How to make Swiss Chard Casserole:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. Preheat oven to 375F/190C.
  2. Wash mushrooms if needed and chop into pieces.
  3. Cook chopped onions and minced garlic in olive oil for a few minutes. Add mushrooms and cook with soy sauce.
  4. When mushrooms are done remove the cooked mushroom mixture to a bowl.
  5. I love to make this with chard from my garden, but this time I had to buy some, and I wished I had gotten two bunches. I recommend using a generous amount of chard if you can.
  6. While the mushrooms cook cut away chard stems and chop leaves. (If you’re using garden chard, give them a good wash in a salad spinner.)
  7. Add chopped chard all at once to the pan. It will cook down quickly, about 3 minutes.
  8. Add the partly-cooked chard to the bowl with the mushroom-onion mixture, then stir in grated cheese, Hemp Hearts (affiliate link), and Spike Seasoning (affiliate link).
  9. Beat eggs and add them to the vegetable mixture in the bowl.
  10. You can probably bake this in a 9″ x 13″ casserole dish if you have a big bunch of chard, but I used a dish that was 8″ x 11″ to make six servings. You can also bake it in individual servings using this Mini Loaf Pan (affiliate link). Whichever type of baking dish you use, spray with nonstick spray.
  11. Transfer egg mixture to the baking dish and sprinkle the top with coarsely-grated Parmesan cheese.
  12. Bake the chard casserole about 25-30 minutes.
  13. Serve hot, with a little sour cream to add at the table if desired!

Notes

You can use minced garlic from a jar for this recipe.

I used brown Cremini mushrooms.

Use Gluten-Free Soy Sauce (affiliate link) if needed.

I used about 6 cups chopped chard and wouldn't have minded a bit more chard; you can also use other greens.

I loved this with Hemp Hearts (affiliate link) and you could also use Flaxseed Meal (affiliate link) or just use whole wheat breadcrumbs if you don't care if it's not gluten-free.

Swiss Chard Casserole will keep in the fridge for at least a week, and can be reheated in the microwave.
