Extra Sauce: If you are using a 32-ounce jar of sauce and have 3 1/2 cups sauce, go ahead and use it all!
Freezer Tip:To save on space in freezer and free up your baking dishes. Line pan with plastic wrap. Freeze until solid, about 4 hours. Remove from freezer and run bottom of pan briefly under warm water to loosen. Lift out of pan. Wrap well in plastic then in foil. When ready to bake. Unwrap and discard plastic. Return to baking dish. Use the same parchment paper and foil to cover while baking.
