Ingredients for Southern Squash Casserole

Step-by-Step Preparation of Southern Squash Casserole
Creating a delicious Southern Squash Casserole is not only an enjoyable experience, but it's also a fantastic way to showcase the flavors of summer squash. This guide will walk you through each step, making your casserole preparation a breeze!
Sautéing the Aromatics
Start by melting 1 tablespoon of butter in a large pan over medium heat. Once the butter has melted, toss in ½ cup of diced onion. Sauté the onions for about 7 to 8 minutes, stirring occasionally until they become soft and translucent. This initial step is not just about cooking the onions; it’s about building a solid flavor base. The sweet aroma filling your kitchen is the first sign that you're on the right track.
Cooking the Squash to Perfection
Next, it's time to add the star of the show: the yellow squash. With your sliced squash ready (about 2 pounds' worth), add it to the pan along with the onions. Cook them together for about 10 to 12 minutes, stirring frequently to avoid browning and ensure moisture is released. Crazy, right? But it’s these little moments in the kitchen that make all the difference. While you cook, the squash becomes tender, soaking up the flavors from the onions.
Draining Excess Moisture
After your squash and onions are cooked, it's crucial to drain any excess moisture. This is a simple but essential step. Place a clean kitchen towel in a colander, then transfer the squash-onion mixture onto the towel. Let it drain for at least 5 minutes, pressing gently to remove any excess water. No one likes a soggy casserole. Keeping it dry will only enhance the flavors and texture!
Mixing the Flavorful Mixture
In a large mixing bowl, combine your drained squash and onion with ½ teaspoon garlic powder, ¾ teaspoon salt, and ½ teaspoon black pepper. Then, stir in ½ cup of sour cream, one beaten egg, 1 cup of shredded cheddar cheese, and ¼ cup of grated Parmesan cheese. This mixture is where the magic happens! The cheese adds creaminess, while the spices elevate the dish to another level.
Preparing the Topping
While your Southern Squash Casserole mixture is resting, let’s prepare the topping. Melt the remaining 3 tablespoons of butter, then mix this with ½ cup of grated Parmesan cheese and your crushed butter crackers (about 25 crackers). The buttery crunch on top will create a delightful contrast with the creamy squash layer below.
Baking the Casserole
Finally, it’s time to bring it all together. Scrape your squash mixture into a 1.5-quart baking dish (an 8x8 square dish works just beautifully). Spread the buttery cracker topping evenly over the top. Now, pop it into the oven preheated to 350°F and let it bake for about 25 minutes, or until the top is golden and crispy. Your kitchen will smell incredible while you wait—just try not to peek too often!
Enjoy your Southern Squash Casserole as a comforting side dish or a delightful main course. With these steps, you're well on your way to impressing friends and family alike. Happy cooking!

Variations on Southern Squash Casserole
Adding Protein: Turkey Bacon Twist
For those looking to amp up the Southern Squash Casserole, consider adding a bit of turkey bacon. Cook and crumble two to four slices before mixing them into the squash mixture. This not only provides a tasty crunch but elevates your dish with a protein boost. The smoky flavor contrasts beautifully with the creaminess of the casserole, making it a hearty meal on its own or a delightful side for grilled chicken. Enjoy with a light salad for a balanced dinner.
Make it Vegetarian: Creative Alternatives
If you’d prefer a meat-free version, there are plenty of creative alternatives. Try substituting the turkey bacon with sautéed mushrooms or even chickpeas for added texture and protein. Another idea is to sprinkle in some fresh spinach or kale for a pop of color and nutrients. You’ll enjoy a deliciously comforting Southern Squash Casserole that aligns perfectly with your vegetarian lifestyle. And for additional flavor, consider enhancing the dish with spices like smoked paprika or a pinch of crushed red pepper for some heat.
Experimenting with these variations opens up a world of flavors and makes your casserole even more enjoyable. Happy cooking!
