Spinach and Mushroom Mostaccioli Casserole
Who doesn’t love comfort food? Not only is it delicious, it has a way of soothing the soul and making your insides feel all warm and cozy. This casserole has to be one of my favorite “comfort food” meals. It’s rich, creamy, flavorful, and oh so satisfying. We used to make it all the time when I was little using regular pasta, heavy cream, and ham instead of the mushrooms, but to be honest, I love this version so much more!
Why This Recipe is Better
Subbing the coconut cream for the regular heavy cream adds a much richer flavor that just makes your tastebuds burst with happiness! Plus, the coconut cream provides those healthy MCTs (medium chain triglycerides–read more here) that get absorbed right into your system, bypassing the digestive tract! The green lentil pasta also adds a nice protein and fiber kick that’ll be sure to keep you satisfied.
Thinking of Making Regular Mostaccioli?
Kick that traditional mostaccioli recipe to the side and try this irresistible twist instead! You might never go back to regular mostaccioli again!
