Description
Southern Squash Casserole brings southern comfort right to your dinner table with a creamy, cheesy twist that’ll make your family ask for seconds. Packed with fresh yellow squash and a surprising cracker crumb topping, this classic side dish delivers pure comfort on a plate.
Ingredients
Protein and Dairy:
- 6 slices bacon, chopped
- ½ cup grated Parmesan cheese
- 1 cup heavy cream
Vegetables:
- 2 pounds yellow squash, thinly sliced
- 1 large onion, thinly sliced
Seasonings and Toppings:
- ¼ teaspoon salt
- ¼ teaspoon black pepper
- ¼ cup breadcrumbs
Instructions
- Warm your oven to 375°F, creating the perfect environment for a rich, comforting casserole.
- Render the bacon in a large skillet over medium heat until it turns deliciously crisp and golden. Transfer the bacon pieces to a paper towel, reserving the flavorful drippings in the pan.
- Sauté the thinly sliced onion in the bacon fat, stirring occasionally. Allow them to soften and caramelize for 10-15 minutes, developing a deep, sweet flavor.
- Slice 2 pounds of yellow squash into thin rounds, ensuring uniform cooking and texture.
- Combine the squash slices, crispy bacon bits, and caramelized onions in a spacious mixing bowl.
- Pour 1 cup of heavy cream over the vegetable mixture, then sprinkle ½ cup of Parmesan cheese, ¼ teaspoon of black pepper, and ¼ teaspoon of salt. Stir thoroughly to distribute the seasonings evenly.
- Transfer the creamy mixture to a 9×13 inch baking dish, spreading it out in an even layer.
- If you enjoy a crunchy topping, scatter ¼ cup of breadcrumbs across the surface for added texture.
- Slide the casserole into the preheated oven and bake for 30-35 minutes until the edges bubble and the squash becomes tender.
- Allow the casserole to rest for 5 minutes after removing from the oven, which helps the creamy sauce settle and intensify its flavors.
Notes
- The secret to perfectly caramelized onions is patience, letting them slowly cook and develop deep, sweet flavor without burning.
- Slice squash uniformly to ensure even cooking and a consistent texture throughout the casserole.
- Use thick-cut bacon for maximum flavor and a satisfying crunch that contrasts with the creamy squash.
- For a lighter version, substitute half-and-half for heavy cream and use turkey bacon instead of traditional bacon.
