How to Make Potato Squash Casserole
Step 1: Preheat and Prep
Preheat the oven to 375°F and lightly coat a 9×9-inch baking dish with 1 tablespoon of softened butter, ensuring the bottom and sides are evenly greased.
Step 2: Cook the Vegetables
Bring a large pot of water to a boil and add the diced potatoes and butternut squash. Cook for 8–10 minutes, or until the vegetables are fork-tender but still hold their shape. Drain the vegetables well in a colander and set aside.
Step 3: Mix the Cream Sauce
In a medium mixing bowl, combine the heavy cream, garlic powder, dried thyme, salt, and black pepper using a whisk or fork until the mixture is smooth and fully blended.
Step 4: Assemble the Casserole
Arrange the cooked potatoes and squash in an even layer in the prepared baking dish. Pour the cream mixture evenly over the vegetables, then sprinkle the finely chopped onion on top.
Step 5: Bake to Perfection
Distribute the shredded cheddar cheese evenly over the dish, then dot the surface with the remaining tablespoon of softened butter. Bake uncovered in the preheated oven for 25–30 minutes, or until the cheese is melted, bubbly, and golden brown. Remove from the oven and let the dish rest for 5 minutes before serving.

Mistakes to Avoid
Even the simplest recipes can have their pitfalls, and this Potato Squash Casserole is no exception. One common mistake is overcooking the vegetables, which can leave them mushy.

Using too much liquid is another issue that can make the casserole soggy. I’ve learned to measure the cream or milk carefully and adjust based on the moisture of the vegetables.

Don’t be shy with the salt, pepper, and herbs—they bring out the natural flavors of the squash and potatoes.

Just wrap it tightly in foil or place it in a freezer-safe container.
When reheating, I like to cover the casserole with foil and warm it in the oven at 350°F until it’s heated through. This helps retain its creamy texture.
