Step-by-step Preparation of Southern Squash Casserole
Southern Squash Casserole is a dish that effortlessly combines comfort and nostalgia. It’s a side dish that brings family and friends together, especially during those backyard BBQs or family gatherings. Let’s dive into the simple steps to prepare this delicious casserole.
Sautéing the Onions
First, in a large pan set over medium heat, melt 1 tablespoon of butter. Then, toss in ½ cup of diced onions. Sauté the onions for about 7 to 8 minutes, stirring occasionally, until they become soft and translucent. This step not only builds flavor but also sets the foundation for your casserole.

Cooking the Squash
Next, add your 2 pounds of sliced yellow squash to the pan. Cook them for 10 to 12 minutes, stirring frequently to prevent them from browning. We want the squash to become soft and release its moisture. This is also a good time to season things up!

Draining Excess Moisture
Once your squash is tender, it's vital to drain the excess moisture to avoid a watery casserole. Grab a colander and place a clean towel inside. Add the cooked squash and onions to the colander and let them drain for at least 5 minutes. Press down gently to squeeze out any additional liquid. This step can't be skipped if you want that perfect texture.
Mixing the Casserole Ingredients
In a large mixing bowl, combine the drained squash and onions with the following ingredients:
- ½ teaspoon garlic powder
- ¾ teaspoon salt
- ½ teaspoon black pepper
- ½ cup sour cream
- 1 beaten egg
- 1 cup shredded cheddar cheese
- ¼ cup grated Parmesan cheese
Make sure to mix everything thoroughly. The cheeses add a creamy texture that really elevates the flavor of the Southern squash casserole.
Preparing the Topping
In a separate bowl, melt the remaining 3 tablespoons of butter. Stir this melted butter together with an additional ¼ cup of Parmesan cheese and 1 cup of crushed butter crackers (about 25 crackers). This mixture creates a crispy topping that adds texture and richness to your casserole.
Baking to Perfection
Now it's time to bring everything together. Scrape the squash mixture into a greased 1.5-quart baking dish (an 8x8 square works perfectly). Evenly sprinkle your buttery cracker topping over the casserole. Bake in a preheated oven at 350°F for about 25 minutes, or until the top is golden brown and bubbly.
And there you have it—the perfect Southern squash casserole is ready to be devoured! Enjoy this comforting dish with your loved ones, and watch as they come back for seconds (and maybe thirds)!

Variations on Southern Squash Casserole
Southern squash casserole is incredibly versatile, opening the door for delicious variations that can fit any palate. Whether you're a cheese lover or looking for a veggie boost, there’s something for everyone.
Adding Different Cheeses
Why stop at cheddar and Parmesan? Experiment with a blend of cheeses, such as mozzarella for stretchiness or pepper jack for a spicy kick. These combinations can elevate the flavor profile of your classic southern squash casserole, making it even more appealing.
Incorporating Other Vegetables
Don’t hesitate to sneak in other veggies! Chopped bell peppers, zucchini, or even spinach can enhance the nutritional value and taste. For a fun twist, try adding corn for a sweet crunch or sweet potatoes for a hearty addition. Each vegetable can bring a unique flavor that complements the squash beautifully.

Cooking Tips for Southern Squash Casserole
Choosing the Right Squash
To make the best Southern squash casserole, start with fresh yellow squash. Look for squash that’s firm to the touch and free of blemishes. Varieties like crookneck and straightneck offer great flavors. If you can, choose squashes that are medium in size, as these tend to have fewer seeds and better texture for baking.
Preventing a Watery Casserole
One common issue when making a squash casserole is excess moisture, which can lead to a soggy dish. To combat this, be sure to drain your cooked squash thoroughly after sautéing. You can use a colander lined with a clean kitchen towel to catch the squash while allowing moisture to escape easily. Press down gently to squeeze out any extra liquid before mixing in the other ingredients. For more helpful tips on preventing watery casseroles, check out The Kitchn.
