This Easy Southern Squash Casserole is a warm and cozy dish made with fresh squash, creamy cheese, and crunchy topping. It’s the perfect side for any meal!
Let’s face it, the cheesy goodness is hard to resist! I love serving this as a happy companion to grilled chicken. Trust me, everyone will be back for seconds! 😋
Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash gives this dish a mild flavor and soft texture. If you can’t find yellow squash, zucchini is a great substitute and works just as well!
Onion: I use a medium onion for its sweetness. If you prefer a milder taste, try green onions or shallots. You can even skip it entirely if you’re not a fan!
Cheddar Cheese: Shredded cheddar adds creaminess and a nice flavor. For a twist, substitute with Monterey Jack or a mix of cheeses like mozzarella and parmesan for variation.
Sour Cream and Mayonnaise: These ingredients contribute creaminess. If you’re looking for a lighter option, Greek yogurt can replace sour cream or mayo, keeping a tangy flavor.
Crushed Buttery Crackers: These create a crunchy topping. Instead, you can use bread crumbs, corn flakes, or even crushed tortilla chips for a different texture and taste.
How Can I Make Sure My Casserole is Creamy and Flavorful?
The key to a creamy squash casserole is to mix the ingredients thoroughly and ensure the squash isn’t watery. Here are some tips:
- Boil the squash for just 5 minutes. This softens it without making it too mushy. Drain well, then pat dry with a paper towel.
- Mix the cooked squash with cheese, sour cream, eggs, and other ingredients until well combined for a uniform consistency.
- Season to taste! Adding a bit more salt and pepper can elevate the flavor. You can also try adding herbs like thyme or a dash of hot sauce for an extra kick.

Ingredients You’ll Need:
For the Casserole:
- 4 cups fresh yellow squash, sliced
- 1 medium onion, finely chopped
- 1 cup shredded cheddar cheese
- 1 cup sour cream
- 2 large eggs, beaten
- 1/2 cup mayonnaise

Seasoning:
- 1 teaspoon salt

How Much Time Will You Need?
This delicious casserole takes about 15 minutes to prepare. After that, it will bake for 30-35 minutes in the oven. In total, plan for about 45-50 minutes from start to finish, plus a little cooling time before serving.
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C) so it’s nice and hot for your casserole. Grease a 9×13-inch baking dish lightly to prevent sticking.
2. Prepare the Vegetables:
In a large pot, bring salted water to a boil. Add your sliced yellow squash and chopped onions, cooking them for about 5 minutes until they are just tender. Once done, drain them well and use a paper towel to pat them dry and soak up any extra moisture.
3. Mix the Filling:
In a large mixing bowl, combine the cooked squash and onion with the shredded cheddar cheese, sour cream, beaten eggs, mayonnaise, salt, black pepper, and garlic powder if you like. Mix everything together until it’s well blended and creamy.
4. Transfer to Baking Dish:
Carefully pour the squash mixture into the greased baking dish and spread it out evenly. This ensures each bite will be delicious!
5. Make the Crunchy Topping:
In a small bowl, mix the crushed crackers with the melted butter until the crumbs are well coated. This will give you that nice crunchy topping. Sprinkle this mixture evenly over the casserole.
6. Bake the Casserole:
Place the baking dish in the preheated oven and bake it uncovered for about 30-35 minutes. Keep an eye on it; you want the casserole to be bubbly and the topping to be golden brown.
7. Serve and Enjoy:
Once it’s out of the oven, let it cool for a few minutes before serving. This gives it a chance to set a little. Enjoy your wonderful Easy Southern Squash Casserole, perfect as a side dish or even as a main meal!
