• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 1 cup shredded cheddar cheese
• 0.5 cups sour cream

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a 9x13-inch casserole dish and set aside.

Step 2

Wash the yellow squash and slice it into thin rounds. Dice the onion into small pieces.

In a large skillet, melt 3 tablespoons of butter over medium heat. Add the sliced squash and diced onion to the skillet, and sauté until the vegetables are softened, about 8–10 minutes.

Step 4

Season the vegetable mixture with salt and black pepper, stirring to combine. Remove the skillet from the heat.

Step 5

In a large mixing bowl, combine the sautéed squash and onion with the shredded cheddar cheese and sour cream. Mix until well incorporated.

Step 6

Transfer the squash mixture to the prepared casserole dish, spreading it out evenly.

Step 7

In a small bowl, mix the crushed crackers with 2 tablespoons of melted butter until the crackers are coated.

Step 8

Sprinkle the cracker mixture evenly over the top of the squash in the casserole dish.

Step 9

Bake in the preheated oven for 25–30 minutes, or until the top is golden brown and the casserole is bubbly.

Remove from the oven and let it cool for 5 minutes before serving. Enjoy!
