This is a lower-fat, no-boil version of Julesong's Creamy Spinach Mushroom Lasagna. After one bite, my 11 year old son said, "make this again, Mom." Many thanks to Julesong for this delicious combination of flavors.

Ingredients Nutrition


  1. Melt 1 tablespoon butter in a large sauté pan over medium-high heat; add the mushrooms and cook until golden, about 5 minutes.
  2. Add the onions and garlic, and sauté for 3 minutes.
  3. Add the drained, chopped spinach, salt, and pepper, stir well and sauté for an additional 5 minutes.
  4. Over medium heat melt 4 tablespoons butter in a saucepan; add the flour and cook, stirring constantly to keep it from browning.
  5. Gradually add the chicken or vegetable broth and milk; cook, stirring occasionally, until smooth and thickened, about 5 minutes.
  6. As soon as sauce begins to boil, remove it from the heat and add thyme and basil.
  7. Combine the shredded cheeses together until well mixed.
  8. Pour 1/2 cup of the sauce into the bottom of a 9x13-inch baking pan.
  9. Lay 5 noodles in a single layer in the pan. (Four the long way and one broken-off one the short way.).
  10. Layer with 1/2 each of the mushroom/spinach mixture and shredded cheeses, then coat with 1/2 of the sauce.
  11. Repeat the process, ending with the sauce.
  12. Cover the pan tightly with foil and bake at 350F for 45 minutes, then remove foil and bake 15 minutes longer.
  13. Remove from oven and let sit a few minutes before serving.

This was a huge hit at my Christmas party. It has such a different flavor than traditional Italian lasagna. I used smoked gruyere instead of havarti and it added a really deep flavor to the cheeses. I also added a layer of ricotta to make the dish higher. And sauteed fresh rather than frozen spinnach. Delish!

This was a huge success. I didn't know how many guests I would have, so I made a double recipe of this in my roasting pan. I doubled all ingredients except the cheeses (used 8 oz ea) and butter, but added some leftover proscuitto (highly recommended). I also did not quite double the liquids because I was pre-boiling my noodles. I layered sauce, noodles, veggies, proscuitto, cheese, N, S, V, P, C, N, S, C. I made it the afternoon before. To cook it, I baked 45 min, then let stand 20 min or so. We wound up being 9 people, and by the time everyone was finished, I ended up with about a 2" x 3" block as leftovers! That was the only downside to the whole thing (we were secretly hoping for more leftovers!). It was great because the only dish at the end of the evening was the roasting pan. Thanks for a wonderful recipe and a successful evening.

Nice change, very delicious!! Easy to put together. I used fresh spinach but otherwise followed the recipe! Thanks for another favorite.
