Lovely recipe. I did end up tripling the amount of butternut squash & then roasting it (so the end volume was more then the origial recipe, but not triple the amount). Roasted squash cannot be beat! I also used a combo of fresh sage & basil in place of the parsley as I think sage is a nice compliment to squash.
This is absolutely delicious!! I will definitely be making this dish again. I steamed the squash until it was just tender instead of microwaving it. I will probably use more squash next time. The sauce was very easy to prepare and added very little to the overall time. Fresh basil just can't be beat ( I doubled the amount in the recipe). The sauce is very very tart and is a perfect match for the sweetness of the squash. I loved the provolone cheese in the recipe. I also carmelized the onions before adding the spinach.
This was so much work for something that tastes okay. I would not make this again. The only thing I changed was that I didn't buy fresh oregano and basil for the sauce, I just bought tomatoes with oregano and basil. I thought everything tasted okay except for the butternut squash. It just doesn't right.
Very, very good! I found one large butternut squash to be more than enough. I was a little worried about butternut squash in my lasagna, but it was devine. Served it to a crew of carnivores and they loved it!
Fabulous recipe. Made a 9x13 pan and it made for a tall lasagna...I might add the squash to the onion mixture and then layer it next time. I made some changes: roasted the squash instead of microwave it and I used 2 cans of fire roasted tomatoes for the sauce, and I caramelized the onions before wilting the spinach. Added some crushed red pepper to the smoky marinara too. Boyfriend loved it!!! Will be making it again.
This was by far the most delicious vegetarian lasagna I've ever made. I took the easy way out and used store-bought marinara sauce instead of making my own, but it still turned out awesome. I couldn't find shredded provolone cheese in my grocery store so I subbed an Italian blend of parmesan, swiss and provolone. Definitely worth the time and effort it takes to make this dish. Yummy!!!
I really enjoyed this lasagna - it tasted great! I did roast my squash rather than microwave it. I found that the quantity of squash called for in the recipe to be very sparse (especially if it is roasted, and it shrinks!). Next time I would double the quantity of squash called for in the recipe. I also made the homemade smoky marinara - it was fairly simple and worth the extra steps.
