  • 1 (12 oz.) package whole wheat lasagna noodles, cooked to package directions
  • 1 head raw cauliflower
  • 1/4 pound white mushrooms, sliced
  • 4 cups 1% milk
  • 1/4 cup whole wheat flour (we used white whole wheat flour)
  • 1 large white onion, chopped
  • 1 tbsp. onion powder
  • 2 tbsp. olive oil
  • 1-1/4 cup grated parmesan cheese (the real stuff)


  1. Cook the pasta as directed. Once cooked, drain and refill pot with cold water. This will keep your noodles from sticking together.
  2. Saute the onion in 1 tbsp. olive oil over low to medium heat. When finished, add the second tablespoon of olive oil and quickly whisk in the flour.
  3. Whisk in the milk, a little at a time, being sure to dissolve any clumps from the flour with the whisk.
  4. Do not stop whisking because the flour burns in the pan very easily, even after the milk is added.
  5. Add the onion powder and then 1 cup of the cheese. You should have a relatively thick sauce at this point.
  6. Remove from heat.
  7. In a lightly oiled lasagna pan (ours was 9X13), place the first layer of noodles on the bottom.
  8. Add a layer of cauliflower, then mushrooms and then sauce. Repeat.
  9. Finish with noodles on top and then sprinkle with the remaining 1/4 cup parmesan.
  10. Cover lightly with foil and bake at 350 degrees F. for about 1 hour to 1 - 1/2 hours, or until cauliflower is soft and cooked through.
  11. CAUTION! Because of the cauliflower, this lasagna retains it's heat in a big way. So allow ample time for it to cool down.
  12. NOTE: Just in case you make this and end up feeling like lasagna should really have red sauce, this is excellent with a little marinara over it too. Enjoy!

    Can this be made with almond milk instead of whole milk?

      Ann, Should work fine. The taste will be a little different, but that's okay.

    How do you prepare the cauliflower for this recipe?

    My sauce was extremely runny 🙁 will it thicken in the oven?

      Kelli, Did you add the 1/4 cup all purpose whole wheat flour to the olive oil? You should let the flour get a little golden and fragrant, incorporating with the oil and onions to form a paste, and stirring all the while. The milk should be added in a gradual stream stirring all the while. The olive oil and flour is called your roux(sometimes they are butter based), once you gradually whisk in the milk a bechamel sauce is formed, and adding any cheese will turn it into a mornay sauce. Was the milk you used 1% or higher?

        Yes I used the flour. I used skim milk b/c that is all I had. I have since made it again and it was still
        runny 🙁 It was also bland. I used garlic powder and onion powder. Is there something else I could use to give it some more flavor?

        • SkinnyMs  February 16, 2015

          Kelli, Parmesan cheese and 2% milk. Make sure a paste forms with the flour before you slowly whisk in the milk, and add parmesan at this stage as well.
