Ingredients

4 cups yellow squash, sliced (about 4–5 medium squashes)
1 small onion, finely chopped
1 cup sharp cheddar cheese, shredded
½ cup sour cream
⅓ cup mayonnaise
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon garlic powder
2 large eggs, beaten
1 cup Ritz crackers, crushed (about 24 crackers)
3 tablespoons unsalted butter, melted
Optional: ¼ teaspoon paprika for topping

Directions

Prep and Preheat

Preheat your oven to 350°F (175°C).
Grease a 2-quart Casserole dish with nonstick spray or butter.

Cook the Squash

Add sliced squash and chopped onion to a large skillet with a splash of water.
Cook over medium heat for 8–10 minutes until squash is tender and most liquid is absorbed. Drain any excess moisture and let cool slightly.

Mix the Filling

In a large mixing bowl, combine sour cream, mayonnaise, eggs, salt, pepper, and garlic powder.
Stir in the cooked squash and onions, then fold in shredded cheddar cheese.

Assemble

Spread the squash mixture evenly in the prepared Casserole dish.
Mix crushed Ritz crackers with melted butter.
Sprinkle cracker mixture evenly over the casserole. Add paprika if desired.

Bake

Bake for 30–35 minutes, or until top is golden brown and casserole is bubbling.
Let cool for 10 minutes before serving for best texture.

Notes

Drain squash thoroughly after cooking to avoid a watery casserole.
Use freshly grated cheddar for maximum melt and flavor.
For a deeper flavor, try sautéing the onions until just caramelized before mixing.

Variations

Spicy Kick: Add ½ teaspoon crushed red pepper or diced jalapeños for extra heat.
Gluten-Free: Substitute gluten-free crackers or panko for the topping.
Protein-Packed: Fold in 1 cup cooked, diced chicken or turkey for a hearty main dish.

Required Equipment

Storage Instructions

Store cooled leftovers in an airtight container in the refrigerator for up to 4 days.
Reheat individual portions in the microwave, or the whole casserole in a 325°F oven for 15 minutes.
Freezing is not recommended, as the texture may become watery after thawing.

Pairings & Serving Recommendations

Pair with roasted chicken, baked ham, or grilled pork chops for a balanced meal.
Serve alongside fresh garden salad and cornbread for classic Southern comfort.
Add a dash of hot sauce or a drizzle of ranch if you like extra flavor!

Pro Tips

Let the casserole rest for at least 10 minutes after baking for easier slicing and serving.
Slice squash thinly and evenly for even cooking and a tender texture.
If using larger squash, cut away any large seeds to maintain a creamy texture.
