Ingredients

For the Casserole

  • Yellow squash: The base of the casserole, providing a mild flavor and tender texture when cooked.
  • Onion: Adds flavor and depth to the casserole.
  • Butter: For sautéing the squash and onion, adding richness to the dish.
  • Eggs: Help bind the ingredients and create a cohesive texture.
  • Heavy cream or sour cream: Adds creaminess and a tangy flavor that enhances the casserole.
  • Cheddar cheese: Sharp cheddar cheese melts perfectly into the casserole, providing flavor and richness.
  • Mozzarella cheese: Adds a mild, melty texture to the casserole.
  • Salt and pepper: For seasoning the dish and bringing out the natural flavors.

For the Topping

  • Breadcrumbs: The topping adds a crispy, crunchy texture.
  • Parmesan cheese: Sprinkled on top for added flavor and to help brown the breadcrumbs.
  • Butter: For melting into the breadcrumbs and giving them a rich, golden color.

Instructions

Step 1: Prepare the Squash

Slice the yellow squash into thin rounds. If desired, lightly salt the squash slices to draw out excess moisture. Let them sit for about 10 minutes, then pat dry with a paper towel to remove any excess water.

Step 2: Sauté the Squash and Onion

In a large skillet, melt the butter over medium heat. Add the onion and sauté until softened, about 5 minutes. Add the squash slices and cook for another 5-7 minutes, stirring occasionally, until the squash is tender and most of the moisture has evaporated.

Step 3: Make the Casserole Mixture

Preheat your oven to 350°F (175°C). In a large mixing bowl, combine the sautéed squash and onion with the eggs, heavy cream or sour cream, and cheddar cheese. Stir until everything is well combined. Season with salt and pepper to taste.

Step 4: Assemble the Casserole

Transfer the squash mixture into a greased 9×13-inch baking dish, spreading it evenly.

Step 5: Prepare the Topping

In a small bowl, melt the butter and mix it with the breadcrumbs and parmesan cheese. Sprinkle this mixture evenly over the top of the casserole.

Step 6: Bake

Place the casserole in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the casserole is bubbly around the edges.

Step 7: Serve

Allow the casserole to cool for a few minutes before serving. Enjoy this comforting Southern dish with your favorite meals!

Tips for Success

  • Don’t skip the salting step: Salting the squash before cooking helps to draw out excess moisture, preventing the casserole from being too watery.
  • Customize with seasonings: You can add other seasonings such as garlic powder, onion powder, or cayenne pepper for extra flavor.
  • Make ahead: You can assemble the casserole a day ahead, cover it, and refrigerate it until you’re ready to bake.

Ingredients

Scale
  • 2 pounds yellow squash, sliced 1/4 inch thick (about 5 medium-sized squash)
  • 1/4 cup butter, divided
  • 1/2 cup diced onion
  • 1/2 teaspoon garlic powder
  • 3/4 teaspoon salt

    • Add the sliced squash and cook for 10-12 minutes, stirring frequently until the squash is soft and releases moisture.
  • Drain Excess Moisture:
    • Place a towel in a colander to prevent the squash from slipping through. Transfer the cooked squash and onions into the towel-lined colander.
    • Let it drain for at least 5 minutes, pressing out any extra moisture.

  • Bake:

Notes
