Roasted Butternut Squash and Spinach Skillet Lasagna

Roasted Butternut Squash and Spinach Skillet Lasagna

This Roasted Butternut Squash and Spinach Skillet Lasagna is the perfect baked pasta for busy fall weeknights. Seasonal roasted butternut squash and spinach jive with a creamy sauce and lasagna noodles. I love that this all comes together in one pan making clean up super easy. It’s so yummy, a little cheesy, and adaptable! You can use mild Italian sausage, plant based sausage or sun dried tomatoes to bring this dish up one more level on the Yum-O-Meter. We are going to call for sausage in this dish. If your large skillet can fit in your fridge, this is also a great dish to make ahead. Skillet lasagnas are simply genius. I love ’em!

Why am I LOVING skillet lasagnas?

  • One pan cooking.
  • Fast cooking.
  • My kids will eat always eat this because they like their food deconstructed and this dish lends to that.
  • Adaptable and flexible. For instance, If you have a family member that doesn’t eat squash you can easily work around the squash when you serve this, but I highly recommend those picky eaters give it a try.
  • Go light on the carbs, or leave out the meat. Take your pick from the skillet and everyone is happy.

The Things:

  • Cutting board and knife
  • Oven safe skillet
  • Stock pot
  • Whisk

The Hacks/Tips:

  • Can of condensed cream of celery soup
  • Buy the butternut squash already peeled, seeded and cut (fresh or frozen)
  • If this store-bought option is not available for you, use a fork to poke holes in your squash and roast the whole thing on the weekend. When it’s soft, cut it open, take the seeds out, and store in your fridge until you are ready to skin, cube and brown it.
  • Reserve your pasta stock when you boil the noodles
