Potato squash casserole is a hearty and satisfying dish featuring tender layers of potatoes and squash baked with a rich, cheesy sauce. This warm, comforting casserole is perfect for cozy dinners or as a side dish for holiday gatherings.
Ingredients (for 6-8 servings):
2 medium potatoes, thinly sliced
2 medium yellow squash or zucchini, thinly sliced
1 cup shredded cheddar cheese
½ cup grated Parmesan cheese
1 cup heavy cream
2 garlic cloves, minced
1 tsp fresh thyme leaves (or ½ tsp dried thyme)
Salt and pepper, to taste
2 tbsp unsalted butter, melted
Optional: ½ cup breadcrumbs for topping
Instructions:
Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish or similar casserole dish.
In a bowl, mix the heavy cream, minced garlic, thyme, salt, and pepper. Stir in half of the cheddar and Parmesan cheeses, reserving the rest for the topping.
Arrange alternating layers of potato and squash slices in the prepared baking dish, slightly overlapping them like shingles. Season each layer lightly with salt and pepper as you go.
Pour the cream and cheese mixture evenly over the layered vegetables, ensuring it seeps between the slices.
Sprinkle the remaining cheeses evenly over the top. If desired, mix the breadcrumbs with the melted butter and sprinkle over the cheese layer for extra crunch.
Cover the dish with foil and bake in the preheated oven for 30 min. Remove the foil and bake for an additional 15-20 min., or until the top is golden brown and bubbly and the potatoes are fork-tender.
Let the casserole cool for 5 min. before serving. Garnish with fresh thyme if desired.
