Step-by-step instructions for making Southern Squash Casserole
This simple Southern Squash Casserole comes together in just a few easy steps. Follow along, and I’ll guide you through it!
Step 1: Preheat the oven and prepare your dish
Preheat your oven to 350°F (175°C). Grease your baking dish lightly with butter or cooking spray. This will prevent the casserole from sticking and make cleanup a breeze.
Step 2: Sauté the squash and onion
In a large skillet, melt the butter over medium heat. Add the sliced squash and diced onion. Sprinkle with salt and pepper.
Cook for about 5–7 minutes, stirring occasionally, until the squash is tender and just starting to soften. Remove from heat and let it cool slightly.
Step 3: Mix the creamy filling
In a large mixing bowl, combine the sour cream and shredded cheddar cheese. Stir in the cooked squash and onion mixture. Mix everything gently but thoroughly to coat the squash in that creamy, cheesy goodness.
Step 4: Assemble the casserole
Pour the squash mixture into your prepared baking dish, spreading it out evenly. Top with the crushed buttery crackers, then drizzle the melted butter over the crackers for that golden, crunchy topping.
Step 5: Bake to perfection
Bake the casserole in your preheated oven for 25–30 minutes, or until the top is golden brown and the filling is bubbly. Let it cool for about 5 minutes before serving.
And that’s it! You’ve just made a delicious Southern Squash Casserole. Serve it warm and watch it disappear fast!
Recipe variations and customization ideas for squash casserole
One of the best things about this recipe is how versatile it is. You can easily tweak it to suit your preferences or dietary needs. Here are some ideas to try:
- Gluten-free option: Swap the traditional cracker or breadcrumb topping with gluten-free breadcrumbs or crushed gluten-free crackers for a celiac-friendly version.
- Vegan-friendly: Skip the cheese and use a plant-based cheese substitute. Replace any dairy with unsweetened non-dairy milk and a vegan butter alternative.
- Make it spicy: Add a pinch of red pepper flakes, cayenne pepper, or a dash of hot sauce to the creamy filling for a little Southern heat.
- Protein boost: Stir in some cooked shredded chicken, ground turkey, or even crumbled sausage if you want to turn this into a main dish.
- Cheese lover’s version: Go all-in with a blend of sharp cheddar, Monterey Jack, and a sprinkle of Parmesan for an ultra-cheesy casserole.
- Crunchy topping twist: Instead of crackers, try French fried onions, panko breadcrumbs, or even crushed cornflakes for extra texture.
- Add more veggies: Toss in some sautéed onions, bell peppers, or even a handful of spinach for extra color and nutrients.
- Make-ahead tip: Assemble everything (except the topping) up to a day ahead and store it covered in the fridge. Add the cracker topping right before baking for the best crunch.
Leftovers can be stored in an airtight container in the fridge for up to three days. Reheat individual portions in the microwave or warm the whole casserole in the oven at 325°F until heated through.
Frequently asked questions about Southern Squash Casserole
Can I make this recipe ahead of time?
Yes, you can! Prepare the casserole up to the point of baking. Cover it tightly and refrigerate for up to 24 hours. When you’re ready to bake, let it sit at room temperature for about 15 minutes, then bake as directed.
What kind of squash should I use?
This recipe works best with yellow summer squash. You can also use zucchini or a mix of both for a slightly different flavor and color.
Why is my casserole watery?
If your casserole turns out watery, it’s likely because the squash released too much moisture. To avoid this, you can lightly salt the squash slices and let them sit for 10 minutes before cooking. Pat them dry with a paper towel before sautéing.
Can I freeze squash casserole?
I don’t recommend freezing this dish, as the creamy filling can separate and become watery when thawed. It’s best enjoyed fresh or reheated from the fridge within a few days.
What can I serve with squash casserole?
This casserole pairs beautifully with roasted chicken, or even a simple green salad. It’s a wonderful side dish for any Southern-inspired meal!
Is this recipe gluten-free?
It can be! Just use gluten-free crackers or breadcrumbs for the topping, and make sure your soup base (if using) and cheese are gluten-free.
