Steps of Preparation
The steps of preparation (possible in all kinds of variations):
Before starting, preheat your oven to 350°F (175°C) to ensure it’s ready for baking when the casserole is prepared.
- Preheat a large skillet over medium heat and add the butter. Once melted, add the chopped onion and sauté for about 5 minutes, or until the onion is soft and translucent.
- Add the sliced yellow squash and zucchini to the skillet. Sauté for another 10 minutes, stirring occasionally, until the squash is tender but not mushy.
- While the vegetables are cooking, prepare the creamy sauce. In a large bowl, combine the cream of mushroom soup, sour cream, shredded cheddar cheese, grated Parmesan cheese, garlic powder, onion powder, salt, and pepper. Mix well until smooth.
- Once the squash and onion mixture is cooked, transfer it to a large mixing bowl and add the creamy sauce mixture. Stir to combine thoroughly.
- Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.
- In a small bowl, mix together the breadcrumbs, grated Parmesan cheese, and melted butter until the breadcrumbs are well-coated.
- Sprinkle the breadcrumb mixture evenly over the top of the casserole, creating a crispy, cheesy topping.
- Bake the casserole in the preheated oven for 30–35 minutes, or until the top is golden brown and the casserole is bubbly.
- Remove the casserole from the oven and let it cool for a few minutes before serving.
- Garnish with fresh parsley, if desired, and serve warm.
Enjoy the creamy, savory goodness of this squash casserole with its perfectly crisp topping. It’s a versatile dish that pairs well with a variety of main courses or stands alone as a satisfying vegetarian meal.
