Oh my goodness.  I found a new recipe to love using butternut squash.  The flavors of cream, nutmeg and a little heat mixed with the sweetness of butternut squash, sage, and garlic in a lasagna is pure heaven!

On Sunday when Rose was visiting and we were making Challah bread, I also made lasagna.  Lasagna happens to be Grumpy’s very favorite casserole dish but I rarely make it.  I’m not a fan of the meaty dish much.  Oh, I can eat it and I don’t think it’s horrible, but I don’t love it.  Never have.  But, I am a fan of butternut squash.  So when I came across a recipe for a lasagna with a bechamel type sauce that also incorporated a ton of flavor using sage, garlic, cayenne and nutmeg, well, I knew it was going to be my dinner!  I promptly decided to make 1/2 a recipe of regular meaty lasagna for Grumpy and 1/2 a recipe of this to die for Butternut Squash lasagna.Butternut Squash, Caramelized Onion, Spinach Lasagna

You gotta love Rose (can I adopt her please?  or maybe introduce her to Chris? ha ha).  She is such a happy young lady with great values and morals.  I have to commend her parents for raising such a beautiful young lady.  When I asked her which one she liked best her comment was the regular lasagna called out to the meat eater in her while she loved the vegetarian one also.  🙂  I promptly sent her home with a piece of each when it was time for her to leave!

No doubt for me however.  This butternut squash recipe has now become my favorite and I will make it again!  It is also diet friendly 🙂  Yay!  I am trying really hard to lose the 12 pounds I’ve gained over this year.  It really stinks getting old and having everything slow down.  The only thing that doesn’t seem to slow down is my life.  Per Dr. Guptil’s instructions, I am bringing exercise back into my life, eating less, and eating healthier.  I hope when I go back in 4 months I can have lost at least half of what I gained this year!

When I made both lasagna recipes I used the Dreamfield lasagna noodles.  These noodles supposedly are a lower carb version of pasta.  I hope so anyway 🙂  BTW, one serving is only 6 WW Points Plus!

    Why use Almond milk if you are going to use dairy cheese?

      Hi Diane, I use almond milk because I don’t drink or like regular milk (pretty sad because I grew up on a farm!). It had nothing to do with the fact that it was dairy. You can use regular milk in this recipe if you wish. It won’t affect the outcome. Thanks for stopping by!
