A comforting cheesy squash casserole that’s easy to make and perfect for gatherings, filled with creamy goodness and packed with flavor.

Ingredients

  • 2 pounds yellow squash (thinly sliced – about 1/4-inch thick)
  • 1/2 sweet onion (finely diced)
  • 3 tablespoons bacon grease (or butter)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 (10.5-ounce) can cream of chicken and mushroom condensed soup
  • 1/2 cup sour cream
  • 2 cups shredded sharp cheddar cheese
  • 1/4 cup unsalted butter (melted)
  • About 30 buttery crackers like Ritz (crushed)

Instructions

  1. Preheat the oven to 350°F and lightly spray a 9×13-inch baking dish with nonstick cooking spray; set aside.
  2. Add the bacon grease to a large skillet over medium heat. Once melted, add the onions and squash. Season with the salt and pepper. Cook, stirring occasionally, until the squash is tender but not mushy—about 10 minutes.
  3. Drain the squash mixture well in a colander to remove excess liquid.
  4. In a large bowl, stir together the undiluted cream of chicken and mushroom soup, sour cream, and cheese. Fold in the drained squash mixture. Spread into the prepared dish.
  5. In a small bowl, combine the crushed crackers with the melted butter until the cracker crumbs are coated. Sprinkle the mixture over the top of the casserole.
  6. Bake, uncovered, for 25 to 30 minutes or until golden brown and cooked through. Allow to rest for about 10 minutes before serving.

Notes

To reduce prep time, consider using pre-sliced squash or frozen squash, but be sure to thaw and drain thoroughly. Adjust the cheese type based on your preferences; a mix of cheddar and mozzarella adds great flavor and creaminess.
