White Cheddar & Squash Casserole Recipe
This White Cheddar and Squash Casserole is like a macaroni and cheese casserole with squash instead of noodles. It is SO good! It will make squash haters change their mind! The best part is this casserole can be made ahead of time and baked later for entertaining. Perfect for a Memorial Day cookout!
This casserole took about 20 minutes to assemble. The squash and onions are sautéed until they are tender. Once the squash is done, a quick cheese sauce is made and tossed with the squash. Finally, pop it in the oven and you have a cheesy and delicious veggie side dish. We served this with some grilled chicken and Fried Okra. YUM!
