Originally this recipe for Swiss Chard and Mushroom Squares was adapted from Regina Schrambling’s Collard Squares, and when I had an abundance of Swiss Chard in the garden this year, I decided to re-do the photos and cook then in individual-sized servings which are great for a grab-and-go breakfast. These veggie-centric squares (that are now rectangles!) have just enough egg to make them breakfast possibilities, but the mushrooms add such savory umami flavor that they could work well for lunch or a light dinner as well.

This is probably the type of dish that will never be too photogenic, but I did like my new idea of cooking them in a Mini Loaf Pan (affiliate link) for more defined portions, and this version also uses Hemp Hearts instead of breadcrumbs to make them lower in carbs and gluten-free. I like to eat these with a dollop of sour cream, as you can tell from the new photo. 

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 if you keep trimming the leaves, it will continue producing new growth all season. It’s also very versatile in cooking, and well worth adding to your vegetable shopping list if you haven’t tried it. And check out my Salute to Swiss Chard for more Swiss Chard ideas!

How to Make Swiss Chard and Mushroom Squares:

(Scroll down for complete recipe with nutritional information.)

  1. First chopped onions and minced garlic are sauteed in olive oil for a few minutes. Then mushrooms are added and cooked with a bit of Tamari or soy sauce.
  2. When they’re done remove the cooked mushroom mixture to a bowl.
  3. I used a generous bunch of chard from my garden, but most every grocery store carries bunches of chard. While the mushrooms cook cut away the chard stems and chop the leaves. (If you’re using garden chard, give them a good wash in a salad spinner.)
  4. The original recipe boiled the chard, but I decided to just saute them in the same pan I had cooked the mushrooms in this time, a good change.
  5. Add chard to the pan all at once. It will cook down quickly, about 3 minutes. This cooks more in the oven so it doesn’t need to be fully cooked at this point.
  6. Combine the mushroom-onion mixture with the barely-cooked chard, then stir in the grated cheese, Hemp Hearts (affiliate link) beaten eggs, and Spike Seasoning (affiliate link).
  7. You can definitely bake this in a 9″ x 13″ casserole dish, but I thought it would be fun to make more defined “squares” by using this Mini Loaf Pan (affiliate link).
  8. Bake the chard squares about 35 minutes at 350F/180C.
  9. Serve hot, with a little sour cream to add at the table if desired!

  12. Spray Mini Loaf Pan (affiliate link) or 9″ X 13″ inch glass or crockery casserole dish with olive oil or non-stick spray.
  13. Pour in egg mixture dividing it among the sections if you're using the loaf pan.

  15. Let cool slightly, then cut into squares if using the casserole dish. Serve hot or at room temperature.
  16. This is good served with sour cream.

Notes

You can also use 2 tsp. 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; can also use other greens. If you don't have Hemp Hearts (affiliate link) you can 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 and Mushroom Squares will keep in the fridge for at least a week, and can be reheated in the microwave.

  1. this sounds pretty much like a baked frittata to me – great way to do it, though! And I just happen to have some chard and mushrooms in my fridge – yay!

  2. Too funny … I’m a bachelor this week while DPaul is traveling for work. I just finished a heaping bowl of quinoa and — swiss chard! It’s maybe not typical bachelor chow, but it’s the sort of stuff I crave when my cro-magnon meat eating husband is away. 🙂

  3. I love swiss chard…especially in frittatas or quiches…makes me think of flans…:)

  4. This looks like a tasty way to include some swiss chard into my meal plan!

  5. Damn I wish I didn’t just go on a low-fat diet!! But maybe I’ll cheat and make this… as an excuse to get my healthy greens!

  6. This looks delicious! I love te square pan. I made a Chard and Roasted Pepper Frittata in August that was tasty. I love the idea of using mushrooms!

  7. Bella, in Utah I can find Ians brand whole wheat Panko crumbs at Wild Oats. That’s the only place I’ve seen them. You could use whole wheat bread and make your own breadcrumbs too.

  8. This looks delicious. I LOVE swiss chard and make it often, but never like this. I can’t wait to try it.

    One question — where do you find whole wheat panko crumbs? I live in the Bay Area in CA (where we can find lots of unusual things), but I can’t seem to find this anywhere. I haven’t made my way to an Asian market yet.

    Any ideas?

  9. Looks fabulous — we grew chard on our farm when I was growing up and love it. Recently, I’ve been having a thing for kale, another yummy leafy green. I’ll have to give this recipe a try — thanks for sharing!

  10. Wow, Kalyn…that looks so tempting! I’m putting swiss chard on my shopping list right away.

  11. This looks so delicious and so original. I’ll be making this for brunch this weekend. Great recipe!

  12. This is my kind of dish — good hot or cold, and using things I always have in the fridge. Thanks for the recipe.

  13. I think spinach would taste great in this. I would probably saute the chopped spinach in a little olive oil rather than boiling it, since spinach cooks so quickly.

    MMM, I’m imagining spinach and feta cheese!

    Thanks everyone who thinks this sounds good, and especially Gretchen for finally inspiring me to make it!

  14. I’ve been looking for fresh Chard or Collard Greens at my local store but they don’t have them. You mentioned substituting other greens…would spinach work? Or should it be more substantial type greens?

  15. These look great and delicious, Kalyn – I love the shape and the flavors as well.

  16. This looks delicious–and a lot better for you than many breakfast stratas. I love mushrooms and greens added to eggs, so this will be perfect!

  17. That look delicious Kalyn. I would love to wrap up a big slab of that and take it with me for lunch. Yum!

  18. I am so glad you were able to try this! I wish I had some chard at home since I have a pack of mushrooms to use up before traveling again. Thanks so much for the mention also!

  19. It looks appetizing and I too enjoy swiss chard…it’s an underused ingredient.

  20. What a good looking and delicious sounding dish! I am so busy, I have no idea for my own submission.
