how long do you cook stuffed shells
Once the stuffed shells are frozen, place them in a plastic freezer bag and seal the bag. Store frozen. To bake the shells, heat the oven to 350Â°F. Continue assembling the recipe just like I showed above but use the frozen stuffed shells, spaghetti sauce and cheese. Bake for 50 to 60 minutes or until the stuffed shells are heated. Add a green salad and some French bread, and your meal is complete. This recipe offers lots of preparation options â microwave, oven, or make-ahead.
