Family Pleasing Cheddar Vegetable Gratin

When I first began making this dish for my family, my boys were little. When I came across a flavor combination that they liked, it tended to show-up rather often on our dinner rotation. Apart from stand-by’s like green bean casserolehot dog cheesy macaroni and cheese and cheesy mashed potato casserole, this gratin  became a regular side dish. I must admit, I love it too. It’s one of those mix-it-all-together then bake until bubbly dishes. The perfect complimentary vegetable side dish to so many entrees, and it’s colorful, too. Another delicious recipe to try are these Honey Garlic Butter Roasted Carrots from Cafe Delights,

  1. Just made this today and my son loves it ! I did something a bit different I mixed the crackers in instead of putting it on top. I’m not huge with crunchy texture and it turned out really good. So easy to make. Thank you ! My house smells so good and it hardly took any time. I’m sort of getting into cooking more so this was great! I recommend it for the kiddos for sure.

      1. He did thank you ! I’m definitely making this again ! It’s so easy to and takes no time love it !
