Mushroom, Rainbow Chard & Gruyere Lasagna

Mushroom, Rainbow Chard & Gruyere Lasagna

I’m a big fan of any kind of baked and bubbly casserole, especially one covered in melty, browned cheese. And even more if that cheese is an aged Gruyere. Last week I was craving lasagna, but didn’t have the traditional ingredients on hand. Don’t you hate when that happens? Not to be downtrodden, I used whatever I had around and made this mushroom, rainbow chard and Gruyere lasagna.

Portabllo and baby bella mushroom are sauteed with onions until browned and almost caramelized, then layered with whole wheat lasagna and Rainbow Chard, ricotta and Parmesan. Cover everything with shredded Gruyere cheese and bake. Definitely much simpler than a traditional lasagna, and much more weeknight-friendly.

While I loved the richness of the mushrooms, I think I used too many. Next time, I’ll use half the amount and add some spicy Italian sausage or ground beef. I’m posting the recipe as I made it below, but am asking you all for any recommendations. What do you think this lasagna needs?

Mushroom, Rainbow Chard & Gruyere Lasagna
You can assemble the lasagna up to 24 hours in advance, then pop it in the oven half hour before your ready to eat.

1 tbsp. olive oil
1 large yellow onion, diced
6 cloves garlic, mined
2 pints baby bella mushrooms, sliced
2 large portabello mushroom caps, chopped
1 tbsp. kosher salt
1 tsp. ground pepper

1 tbsp. olive oil
2 bunches rainbow chard, greens only, sliced into thin ribbons (reserve the stalks for other uses – pasta sauces, stocks, tacos, etc.)
1/4 cup chicken stock (or water)
30 oz. ricotta cheese
1 cup freshly grated Parmesan cheese

1 lb. whole wheat, no-boil lasagna
2 oz. aged Gruyere, freshly grated

Preheat the oven to 375°. Set a large skillet over medium-high heat. Once it’s hot, add the olive oil, then the onions. Saute the onions for 5 – 7 minutes, or until soft and starting to brown. Add the garlic and saute for another minute, then add the mushrooms and continue to cook for 7 – 8 minutes, or until the mushrooms are slightly browned, but not soggy. Remove the contents of the skillet to a bowl.

Return the skillet to the heat and add another tablespoon of olive oil and the ribbons of rainbow chard and stock. Saute for 5 minutes, or until the chard just begins to wilt, then remove from heat and stir in the ricotta and Parmesan.

Now you can begin assembling your lasagna. Place half of the mushroom mixture at the bottom of a 13 x 9 casserole dish. Add a layer of noodles, then place half of the ricotta mixture over the noodles. Another layer of noodles, then the remainder of the mushrooms. Another layer of noodles, then the remainder of the ricotta mixture. Last layer of noodles on top, then cover with the shredded Gruyere.

Bake for 30 – 35 minutes, or until the cheese is browned and crisp. Cut into portions and serve immediately with a big, green salad.

Makes 6 – 8 servings.


  1. I can’t tell you how happy finding your site has made me. I do a long-distance weekly recipe with a dear friend in NYC, and I post about these meals on my otherwise-literary blog. I’m also constantly sharing my kitchen adventures (mostly photos) with readers, and my Mom, via snailmail.

    But going through your site… Well, it makes me nod my head in a ‘THAT’S how it’s done!’ way, as well as making me genuinely excited about cooking. (If I needed any more help!)

    Thanks for putting a smile on my face; am really, really looking forward to trying so many of what you’ve shared here. (Including this lasagna recipe).

    Good cheer to you from The Great White North.

    Of course I’d have to add some red bell pepper just because I add it to almost everything. This sounds amazing!

  3. Delicious! Added some artichoke hearts for good measure… more please!



  4. schmadrian – WOW! Thank you so much! Comments like yours make me want to keep posting when I’m exhausted and don’t feel like cooking :)

    Mary – Good idea…would add nice color too!

    heather – artichoke hearts! duh! I loooooove artichoke hearts :)

  5. Love the ricotta. Makes it so lofty and high.

  6. You had me at the bubbly crisp cheese… ohhhhh… my the connotations.. Adding the mushrooms is just pleasure on perfection.

  7. This sounds so good!

  8. Oh my Gosh! I am so excited to stumble across your site. My sister just bought me a bag of farro and I am so excited to try the soup. I too am an avid food lover, finding a new recipe or trying a new spice gives me a thrill! I am constantly cooking, even though I am tired from work and commuting so I truly appreciate your site…… Kudos to you!!
    Keep Cooking!

  9. Sorry guys —- meant that comment for the farro/kale/soup!

  10. FoodGeekLee – Thanks for the lovely comments! It’s always good to hear :)

  11. I love this combination. Although your recipe is very healthy I have an overwhelming desire to leave out the ricotta and add a bechamel sauce to this. I make a spinach and mushroom white lasagna like that and everyone just loves it!

  12. Danielle – Bechemel sauce would be delicious! GREAT idea!

  13. I made this recipe tonight, and added marsala sauce instead of the stock… delish!! thanks for a great recipe

  14. Well hair of the dog and all, I took my obligatory swig from him and felt like I should use that empty grave for the Vietnam unknown. His strength was fully realized however as he proceeded to swat vampires out of the air with wet, bloody slaps. Before it truly is installed, it might be cleaned with gasoline and kerosene initial and after that spread with good quality lubrication grease.

  15. Thanks for every other wonderful post. The place else may anybody get that type of info in such a perfect means of writing?
    I have a presentation subsequent week, and I’m at
    the look for such info.

  16. I really like what you guys tend to be up too. This kind
    of clever work and reporting! Keep up the superb works guys I’ve
    included you guys to blogroll.

  17. When you purchase a solo ad, your ad is the only message the reader sees,
    and so the name, “solo” is created. It is a full service media agency
    that deals with media planning, marketing and buying in London. It is noticeable
    from all sides and cannot be converted off or ignored.

  18. You think that was it? Because I have been trying to iatlsoe what made it so spicy. It called for 2 tablespoons each of salt and paprika but I cut it down to one. I’ll try cutting the cayenne and black pepper down next time.
