Cook the rotini pasta according to package instructions. Drain and set aside.
In a saucepan, melt butter over low-med heat. Slowly add in flour & mix to combine. Pour in heavy cream or milk and stir well to make a roux. The mixture should be thick, but smooth.
Stir in crushed tomatoes and one pouch of Cerebelly Butternut Squash Chicken Broth. Season with salt and pepper, if desired.
Add cooked rotini pasta and fold into the sauce until coated. P.S. Pasta will cook a bit in the oven, so it’s okay if it is slightly al dente.
Transfer pasta mixture into a greased baking dish. Be careful! Mixture may be hot.
In a separate small bowl, grate parmesan cheese into the panko crumbs and distribute evenly over pasta. Finish with shredded mozzarella.
Broil at 400 F for 5 min, or until the cheese is golden and bubbly.
