Italian Spaghetti Bake

This hearty casserole recipe makes two large baking dishes. The tasty layers of meat sauce, spaghetti and gooey cheese are sure to appeal to pizza-loving kids…and adults. You'll bring home empty pans when you take this to a potluck. —Janice Fredrickson, Elgin, Texas

    I've made this recipe several times. The family welcomes it. We like that it is large enough to have the second day when the flavors are even more pronounced. I tweak it a little depending on what ingredients I have on hand. We like garlic so I add 3 chopped cloves. I have never used the sliced pepperoni as we prefer it with just the beef. Nothing not to like about it and kudos to the developer of it.

    I thought there was too many noodles. if I were to make again, I would only use 1 pound of spaghetti.

    I took this to a church pot luck and the platter came back empty! I'm making this for the second time later this week. My three young boys love it.

    I omit the green peppers and use fresh mushrooms but otherwise follow the recipe. It is a hit whenever i serve it and has a wonderful flavor.

    This recipe is okay. I just personally prefer more sauce with my spaghetti.~ Theresa

    Like the idea of a dish I can put away in the freezer for another time or as a gift for a new mom. I needed to cook the entire recipe for my family (very large family). A little dry so might add to the sauce the next time. I Look for suggestions from others so appreciate the comments made on variations. Relax mailladyrr!

    We make a version of this but we also add Italian hot sausage in addition to the hamburger meat and some sliced green olives and green pepper.

    Didn't care for the addition of pepperoni. Otherwise just okay.
