Do you ever just wish you could enjoy the finer things in life with reckless abandon? Trying to moderate your sodium, sugar, cholesterol, or calorie intake can sometimes feel like walking through a dangerous (yet very temptingly tasty) minefield.

Well, rejoice! This Low-Carb Yellow Squash Casserole is as delicious as sin but you can enjoy as much of it as you want. It satisfies a low-carb diet and provides a convenient way to use up a big harvest of summer squash. Heavy whipping cream for a delightfully smooth and creamy texture, shredded Colby-Monterey Jack cheese for that subtly sweet and slightly tangy bite, topped with smoky, salty roasted almonds — there’s no better way to enjoy summer squash. You can even serve it as a dip during snack time along with some chips and crackers, or you can serve it as a side during lunch or dinner. Instead of your typical mashed potatoes, why not try making this casserole your companion for steak night?

Now, I can’t take all the credit for thinking up this particular casserole — I have to extend my thanks to one of my dear neighbors, who offered it up as a suggestion when I was asking around for recipe ideas. She and her husband had been trying to commit to a healthier diet, and this Low-Carb Yellow Squash Casserole had become a staple in their household’s menu. She traded me tips on how to cook it for some squash from my garden, and I happily obliged. Little acts of kindness make the world go round and the kitchen a happier place — try cooking up this casserole and share some with your neighbors!
