Ingredients You’ll Need for Southern Squash Casserole
When it comes to making a Southern Squash Casserole, the magic is in the ingredients. This dish is all about balance—fresh vegetables, creamy dairy, and that crunchy, buttery topping that makes everyone sneak back for seconds. Below, I’ll break down each ingredient so you know exactly why it’s included and how to choose the best version when you’re at the store or rummaging through your pantry.
- 6 medium yellow squash
Yellow squash is the heart of this dish. Look for squash that feels firm to the touch with a glossy, bright skin—avoid any with soft spots or wrinkles. When cooked, squash adds a natural sweetness and tender bite that makes this casserole so comforting. If you’ve tried my Paleo Roasted Spaghetti Squash – Quick, Healthy, and Amazing Flavor, you already know how versatile squash can be in Southern-style cooking. - 1 small onion, diced
Onion brings just the right amount of savory depth. A sweet onion works beautifully, but a standard yellow onion will do just fine. Dice it small so it melts right into the casserole mixture. - 2 tablespoons butter
Butter is what makes this recipe taste like, well, home. It’s used to sauté the squash and onion, and it adds richness that can’t be beat. - 1 cup shredded cheddar cheese
Sharp cheddar cheese is ideal because it gives the casserole a bold, tangy flavor that pairs perfectly with the mild squash. If you like a little extra creaminess, mix in half cheddar and half Monterey Jack. - 1/2 cup sour cream
Sour cream adds creaminess and a subtle tang. This is one of those ingredients that transforms the casserole from “good” to “wow.” It keeps everything moist and ties the flavors together. - 2 large eggs, beaten
Eggs act as the binder in this dish, helping the casserole set into that perfect, scoopable texture. Without them, the casserole would be too loose. - 1 sleeve buttery crackers, crushed
Ah, the topping. Buttery crackers—like Ritz—are crushed and mixed with melted butter to form that golden, crunchy layer on top. This is the piece that makes folks fight for the corners of the dish. - Salt and pepper to taste
Don’t skip this. Seasoning properly is what makes all the flavors shine. Taste your filling before baking and adjust as needed. - 1/2 teaspoon garlic powder
A little garlic powder adds depth without overpowering. It’s just enough to round out the flavors.
When combined, these humble ingredients turn into something far greater than the sum of their parts. That’s the charm of a Southern Squash Casserole—it takes simple, familiar foods and transforms them into a dish that feels like a warm embrace.
How to Make Southern Squash Casserole (Step by Step)
Making a Southern Squash Casserole is a whole lot easier than it looks, and I’ll walk you through every step so you feel confident from start to finish. Think of this as more than just a recipe—it’s the kind of dish that can bring back memories of Sunday dinners at Grandma’s table, or even start new traditions in your own kitchen.
Step 1: Preheat and Prep Your Dish
Before you even touch the squash, set your oven to 350°F (175°C). This way, it’s ready to go when you are. Grease a 9×13-inch baking dish generously with butter or cooking spray. A little extra love here ensures nothing sticks and makes cleanup easier later.
Step 2: Slice and Dice
Wash your squash thoroughly, then slice into thin, even rounds. Too thick, and they won’t soften properly; too thin, and they’ll turn mushy. Dice the onion finely so it blends seamlessly into the filling—nobody likes a big chunk of onion surprise.

Step 3: Cook the Veggies
In a large skillet, melt 2 tablespoons of butter over medium heat. Add your sliced squash and diced onion, stirring occasionally. Cook for 5–7 minutes until the squash softens and the onions turn translucent. The smell at this point? Pure Southern comfort.
Pro tip: Don’t rush this step. Cooking the veggies properly is key to avoiding a watery casserole later.
Step 4: Mix the Filling
Transfer the cooked squash and onion into a big mixing bowl. Stir in the shredded cheddar cheese, sour cream, beaten eggs, garlic powder, salt, and pepper. Mix until everything looks creamy and well blended. This is when the casserole starts coming together—the squash softens, the cheese melts slightly, and the eggs tie it all into one cozy mixture.
Taste the filling now. If it needs more salt or pepper, add it. Remember, seasoning makes all the difference.
Step 5: Fill the Baking Dish
Spoon the mixture into your prepared baking dish, spreading it evenly. You want every bite to have that perfect balance of squash, onion, and cheese.
Step 6: Add the Crunchy Topping
In a small bowl, combine your crushed buttery crackers with a little melted butter (just enough to coat). Sprinkle the cracker mixture evenly over the top of the casserole. This is the pièce de résistance—the golden, crunchy crown that makes this dish unforgettable.
Step 7: Bake to Golden Perfection
Slide the dish into the preheated oven and bake for 25–30 minutes. You’ll know it’s ready when the casserole is bubbling around the edges and the topping is a beautiful golden brown.
Step 8: Cool and Serve
As hard as it is, let your Southern Squash Casserole cool for about 5 minutes before digging in. This quick rest helps it set so you can scoop clean portions. Then serve warm and watch it disappear faster than you can say “who wants seconds?”
Tips and Tricks for Perfect Southern Squash Casserole
- Don’t overcook the squash before baking—it should be just softened, not mushy.
- Drain well if your squash releases extra liquid; otherwise, the casserole can turn watery.
- Cheese swap: Try Monterey Jack or Colby if you like it milder.
- Make ahead: Assemble up to 24 hours in advance, refrigerate, then bake when ready.
- Double batch alert: This disappears fast at potlucks—trust me, make two.
Storage
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Freeze: Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and reheat in the oven for best texture.
FAQs
Can I use zucchini instead of yellow squash?
Yes, though the flavor will be a little different. A mix of both works nicely too.
What can I use instead of crackers for the topping?
Breadcrumbs, panko, or even crushed cornflakes will give you a different crunch.
Can I make it lighter?
Swap Greek yogurt for sour cream, or use reduced-fat cheese. It’ll still taste fantastic.
