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 the diced onion and sauté for 7-8 minutes until soft and translucent. This will bring out the sweetness of the onion.
Step 2: Cook the Squash
Add the sliced squash to the pan. Cook for 10-12 minutes, stirring frequently, until the squash becomes soft. It should be tender but still hold its shape.
Step 3: Drain Excess Moisture
Drain the cooked squash and onions in a colander lined with a towel. Let it sit for at least 5 minutes while pressing out the excess moisture. This step ensures the casserole is not watery.
Step 4: Combine Ingredients
In a bowl, mix the drained squash and onion with garlic powder, salt, black pepper, sour cream, beaten egg, shredded cheddar cheese, and ¼ cup grated Parmesan. Stir until thoroughly combined, creating a creamy mixture.
Step 5: Prepare the Cracker Topping
Melt the remaining 3 tablespoons of butter. Mix it with the crushed crackers and remaining ¼ cup of Parmesan. This will form a flavorful, crunchy topping.
Step 6: Transfer to Baking Dish
Scrape the squash mixture into a baking dish. Evenly sprinkle the cracker mixture on top to create a delicious crust.
Step 7: Bake
Bake at 350°F for 25 minutes or until the top is golden brown and bubbly. Let it cool for a few minutes before serving. Enjoy your dish!
Pro Tips from My Kitchen
✓ Fresh Squash – Opt for fresh yellow squash for the best flavor and texture. Check for firm, blemish-free squash at the market.
✓ Watch the Moisture – Ensure you drain the squash well. Excess moisture can make the casserole soggy instead of creamy.
✓ Cheese Varieties – Feel free to experiment with different cheese types. Mixing in mozzarella or pepper jack adds variety to the flavor profile.
✓ Make it Ahead – Prepare the casserole in advance and refrigerate before baking. Just add extra baking time if baking straight from the fridge.
✓ Tweak the Toppings – Swap the cracker topping for breadcrumbs or crushed cornflakes for a different crunch and flavor profile.
