This spinach and mushroom pasta is creamy and full of flavor thanks to my favorite garlic parmesan cream sauce. I sautéed onions, garlic, mushrooms and spinach then added cream and parmesan and mixed the cream sauce in with the pasta, topped with mozzarella cheese and baked until bubbly. The result is a creamy, hearty pasta that is sure to please the entire family!Creamy Spinach and Mushroom Pasta BakeCreamy Spinach and Mushroom Pasta Bake Creamy Spinach and Mushroom Pasta Bake Creamy Spinach and Mushroom Pasta BakeCreamy Spinach and Mushroom Pasta BakeThis pasta with spinach and mushrooms comes together in under 30 minutes and stores can be prepped ahead of time and frozen.

    It’s in the oven. Smells delicious. Some warm bread on the side. Perfect snow day dish. Thank you for sharing


      Thanks for the feedback, Patricia! Enjoy 🙂


    Really delicious. Chopped the spinach. I thickened the broth and cream with arrowroot since I’m gluten free. Topped with asiago. Nice subtle nuttiness with the spinach. Thanks for the inspiration. I think it would be good with chopped up ham too.


      Thanks for the feedback! Glad you enjoyed the pasta 🙂


    Looks wonderful but how many serving are in the 13×9″ pan? It tells us that there are 413 calories per serving.

    This was delicious! We used portobellos instead of button, subbed cashew milk for the cream, and added a bit of thyme. My husband had 3 servings, and he’s a meat eater.

    Tried recipe last evening, very delicious!


    Making it now and realize there is no oven temp setting… going with the standard 350 and hoping it doesn’t dry out.


      I got too lost in the recipe! just added the temp. Pre-heat the oven to 375F before doing anything else.


    This pasta bake looks so creamy and packed with flavor! Loving the spinach and all the cheese 🙂 Pinning!
