Absolutely!   This recipe will work great in a glass casserole dish. The standard advice for baking in glass is to lower the oven temperature by 25°F from what the recipe calls for, and bake up to 10 minutes longer. So, for this recipe, you would the stuffed shells at 325 degrees F and bake for 40 minutes.  Also, broiling is not recommended with glass bakeware because it can shatter.
