Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash is key for this recipe. If you can’t find it, zucchini makes a great substitute. It gives a similar texture and flavor, though you might want to adjust the seasoning slightly.
Sharp Cheddar Cheese: I love using sharp cheddar for its rich flavor. If you’re looking for something milder, try Monterey Jack or a blend of cheeses like Gouda and mozzarella for a different taste.
Sour Cream & Mayonnaise: These add creaminess. For a lighter option, Greek yogurt can replace both. It’s tangy and healthy, but may change the flavor slightly.
Crushed Crackers: Buttery crackers are classic for the topping. If you want a gluten-free option, crushed corn chips or almond flour combined with melted butter works well without losing that crunch!
How Do I Deal with Excess Moisture in My Squash?
Getting rid of excess moisture is crucial for a perfect casserole texture. If your squash is watery, the casserole will be soggy. After boiling, be sure to drain the squash well. I like to spread the squash on a clean kitchen towel, fold it, and squeeze out any extra water.
- Boil squash and onion for just 3-5 minutes.
- Drain in a colander and pat dry with a towel.
- Squeezing out moisture ensures a firmer casserole.

Step-by-Step Instructions:

Start by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly and perfectly.

Frequently Asked Questions (FAQ) about Southern Squash Casserole
Can I Use Other Vegetables Instead of Yellow Squash?
Absolutely! While yellow squash is traditional, you can substitute zucchini or even a mix of vegetables like carrots and bell peppers. Just ensure they are chopped and cooked until tender before mixing them in.

Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. To reheat, pop it in the microwave or warm it in the oven at 350°F until heated through.

What Can I Use Instead of Mayonnaise?
If you prefer not to use mayonnaise, Greek yogurt is a great substitute. It adds creaminess and a bit of tang. You could also use more sour cream if you’d like!
