Equipment

  • Large skillet
  • Medium mixing bowl
  • 9x13-inch baking dish

Ingredients
  

  • 6 cups yellow squash thinly sliced (about 4 medium squash)
  • 1 small onion finely chopped
  • 2 tablespoons unsalted butter
  • ½ cup sour cream
  • 1 can 10.5 oz cream of mushroom soup
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • cups shredded cheddar cheese
  • 1 cup Ritz crackers crushed (about 1 sleeve)
  • 2 tablespoons unsalted butter melted

Instructions
 

Step 1: Sauté the squash and onions

  • Start by heating 2 tablespoons of butter in a large skillet over medium heat. Add the sliced yellow squash and chopped onions.
  • Cook for about 8–10 minutes, stirring occasionally, until the squash is tender and the onions are translucent. Remove from heat and set aside.

Step 2: Mix the creamy filling

  • In a medium mixing bowl, combine the sour cream, cream of mushroom soup, salt, black pepper, and garlic powder.
  • Stir until everything is well blended. Add the cooked squash and onions to the bowl, then gently mix to coat the vegetables in the creamy mixture.

Step 3: Add the cheese

  • Stir 1 cup of shredded cheddar cheese into the squash mixture. This adds a rich, cheesy flavor that makes the casserole irresistible. Once mixed, transfer the filling to a greased 9x13-inch baking dish, spreading it out evenly.

Step 4: Make the buttery cracker topping

  • In a small bowl, mix the crushed Ritz crackers with the melted butter. Sprinkle this mixture evenly over the top of the casserole. Finally, sprinkle the remaining 1/2 cup of shredded cheddar cheese on top for extra gooey goodness.

Step 5: Bake to perfection

  • Preheat your oven to 350°F. Bake the casserole for 25–30 minutes, or until the top is golden brown and bubbling. Let it cool for a few minutes before serving, it’s hard to wait, but trust me, it’s worth it!
