Large skillet
Medium mixing bowl
9x13-inch baking dish
- 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
- 1½ cups shredded cheddar cheese
- 1 cup Ritz crackers crushed (about 1 sleeve)
- 2 tablespoons unsalted butter melted
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!
