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.
Step 2: Cook the Squash
Add the sliced yellow squash to the pan. Cook for 10-12 minutes until soft, stirring frequently to prevent browning and encourage moisture release.

Place a towel in a colander to catch any pieces of squash. Transfer the cooked squash and onions to drain for at least 5 minutes. Press out any extra moisture gently.
Step 4: Mix Ingredients
In a mixing bowl, combine the drained squash mixture with garlic powder, salt, black pepper, sour cream, beaten egg, shredded cheddar cheese, and 1/4 cup of grated Parmesan cheese.
Step 5: Prepare the Topping
Melt the remaining 3 tablespoons of butter. Stir this melted butter along with the remaining 1/4 cup of Parmesan cheese into the crushed crackers until well combined.
Step 6: Assemble the Casserole
Scrape the squash mixture into a greased baking dish (8×8 square or similar). Spread it evenly across the bottom.
Step 7: Add Topping
Sprinkle the buttered cracker mixture evenly over the top of your casserole for that delightful crunch.
