How to Make Southern Squash Casserole
Step 1: Sauté the Onions
In a large pan set over medium heat, melt 1 tablespoon of butter. Add 1/2 cup of diced onion to the pan and sauté for 7 – 8 minutes until soft and translucent.
Step 2: Cook the Squash
Add 2 pounds of sliced yellow squash to the pan. Cook for 10 – 12 minutes, stirring frequently to prevent browning and to promote moisture release until the squash is soft.
Step 3: Drain Excess Moisture
Place a towel in a colander so your squash doesn’t slip through. Put the cooked squash and onions on top of the towel to drain for at least 5 minutes, pressing out any extra moisture.

– 1/2 teaspoon garlic powder
– 3/4 teaspoon salt
– 1/2 teaspoon ground black pepper
– 1/2 cup sour cream
– 1 beaten egg
– 1 cup shredded cheddar cheese
– 1/4 cup grated Parmesan cheese
Reserve the remaining Parmesan cheese for later.
Step 5: Prepare Topping Mixture
Melt the remaining 3 tablespoons of butter. Stir melted butter into crushed crackers along with another 1/4 cup of Parmesan cheese.
Step 6: Assemble Casserole
Scrape the squash mixture into a baking dish (size approximately 8×8 square or similar).
Step 7: Add Topping
Sprinkle the buttered cracker mixture evenly over the top of your casserole.

Common Mistakes to Avoid
When making Southern Squash Casserole, a few common missteps can lead to less-than-desirable results. Here are some mistakes to watch out for:
- Using too much moisture: Squash contains a lot of water. Be sure to drain it well after cooking to prevent a soggy casserole.
- Not seasoning enough: Proper seasoning is essential. Don’t skip the salt and pepper; they enhance the flavors of the dish significantly.
- Skipping the egg: The egg helps bind the mixture together. Omitting it can result in a casserole that falls apart instead of holding its shape.
- Neglecting the topping: The buttered cracker topping is a key feature. Ensure you evenly distribute it over the casserole for that crunchy texture.
- Overcooking or undercooking: Follow the baking time closely. Overcooking can dry out the casserole, while undercooking may leave it mushy.
Refrigerator Storage
- Store in an airtight container for up to 3-5 days in the refrigerator.
- Allow the casserole to cool completely before sealing it to maintain freshness.
Freezing Southern Squash Casserole
- You can freeze for up to 2-3 months.
- Use freezer-safe containers or wrap tightly with plastic wrap and aluminum foil.
Reheating Southern Squash Casserole
- Oven: Preheat to 350°F and heat for about 20 minutes or until warmed through.
- Microwave: Place a portion in a microwave-safe dish, cover, and heat for 1-2 minutes, checking periodically.
- Stovetop: Heat in a skillet over low heat, stirring occasionally until heated through.
