Description

A rich and creamy Southern-style squash casserole made with cheddar cheese, sour cream, and a buttery cracker topping. Perfect as a crowd-pleasing side dish for holidays or any family dinner.


Ingredients

Scale
  • 2 lbs yellow squash, sliced into rounds
  • 1 medium onion, chopped
  • 3 tbsp unsalted butter (divided)
  • 2 large eggs
  • ½ cup heavy cream or half-and-half
  • ½ cup sour cream
  • ¼ cup mayonnaise
  • 1 cup shredded cheddar cheese (+½ cup for topping)
  • 1 sleeve buttery crackers (like Ritz), crushed
  • ¼ tsp paprika
  • ¼ tsp garlic powder
  • Salt and pepper to taste

Instructions

  1. Prep the Squash and Onion: Melt 1½ tbsp butter in a skillet over medium heat. Add squash and onions and sauté for 5–10 minutes until tender. Drain in a colander and blot with paper towels. Let cool.
  2. Make the Filling: In a bowl, whisk together eggs, cream, sour cream, mayonnaise, 1 cup shredded cheddar, paprika, garlic powder, salt, and pepper. Fold in the cooled squash and onion mixture.
  3. Assemble and Bake: Preheat oven to 350°F (175°C). Spread the mixture into a greased 9×13-inch baking dish. Top with the remaining ½ cup of cheddar cheese.
  4. Mix the crushed crackers with the remaining 1½ tbsp melted butter and sprinkle evenly over the top.
  5. Bake for 25–30 minutes until the top is golden brown and the casserole is bubbling.
  6. Serve: Let sit for 5–10 minutes before serving to allow it to set.

Notes

For extra flavor, add a pinch of cayenne or substitute a portion of the cheddar with Gruyère. This dish can be made ahead and reheated for potlucks or holiday meals.
