Cheesy Summer Squash Casserole Recipe

This Southern yellow squash casserole is a classic comfort side dish loaded with tender pan-fried squash, sharp cheddar, and a buttery Ritz cracker topping that bakes up golden and crisp. It comes together easily and works just as well for a weeknight supper as it does on the Thanksgiving table.

Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes

Ingredients 

  • 5 to 6 medium yellow squash sliced just a little over ¼ inch thick (you will need about 2 - 2.25 pounds)
  • ⅓ cup diced sweet onion or to taste
  • 3 tablespoons butter
  • 1 teaspoon kosher salt or to taste
  • ½ teaspoon black pepper or to taste
  • 2 ½ cups cheddar cheese shredded, divided
  • 1 large egg beaten
  • 1 cup sour cream

Cracker Topping

  • 1 sleeve ritz crackers crumbled (or saltine crackers)
  • ¼ cup butter melted

Instructions

  • Preheat oven to 350℉. Butter or lightly spray an 11 X 7 dish; set aside.
  • Over medium-high heat, melt butter in a skillet. Add sliced squash, onion, salt, and pepper. Cook while stirring occasionally until the squash is tender, but not mushy (about 10 minutes).
    Drain the squash mixture well in a colander to remove excess liquid.
  • In a large bowl, beat the egg. Add sour cream and 1 cup cheese. Fold in cooked and well-drained squash. 
  • In a small bowl, combine the crushed crackers with melted butter and stir until the crackers are coated. Sprinkle the crushed crackers over the top of the casserole.
  • Pour the squash mixture into the baking dish. Top with the remaining cheese.
  • Bake for 25 to 30 minutes or until golden and bubbly. Allow the casserole to rest for 5 to 10 minutes before serving.

Notes

My mom always used Saltine crackers on top of this. I usually use butter crackers, but make it with saltines from time to time, too.
