Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash is key for its mild flavor and tender texture. If you’re in a pinch, zucchini can be a great substitute, or you can use a mix of both for extra color!
Cheddar Cheese: Sharp cheddar is the star here, bringing a delicious tangy flavor. If you prefer something milder, feel free to use medium cheddar or even a cheese blend. For a lighter option, Monterey Jack works well too!
Eggs: Eggs help bind the casserole together. If you’re looking for an egg substitute, try using 1/4 cup of unsweetened applesauce or a flax egg (1 tablespoon ground flaxseed with 2.5 tablespoons water).
Sour Cream & Mayonnaise: Both add creaminess. If you need a lighter option, Greek yogurt can replace both for a similar texture, offering a bit of tang too!
Crackers: Buttery crackers like Ritz give a nice crunch. However, you can swap them with breadcrumbs or Panko for a crispier topping, or even use crushed cornflakes for a fun twist!
How Do You Properly Cook and Drain Squash?
Cooking the squash might seem simple, but it’s key to prevent a soggy casserole! Here’s how to do it right:
- Start by slicing your squash thinly for even cooking. Aim for about 1/4 inch thick.
- Boil in salted water for just a few minutes until they are slightly tender but not mushy. This usually takes about 3-4 minutes.
- Drain thoroughly and spread the squash on paper towels to soak up extra moisture. You can gently press them with a towel to get rid of any excess water.
- This step is crucial! Less water leads to a better textured casserole, avoiding that watery mess.

Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish with cooking spray or butter to prevent sticking.
2. Cook the Squash:
In a large pot, bring salted water to a boil. Add your thinly sliced yellow squash and cook for about 3-4 minutes until they are just tender. Once done, drain the squash well and allow it to cool. To remove any extra moisture, gently press the squash with paper towels.
3. Mix the Casserole Ingredients:
In a large mixing bowl, combine the cooled squash with the chopped onion, shredded sharp cheddar cheese, beaten eggs, sour cream, and mayonnaise. Give it a good stir until all ingredients are well mixed.
4. Season the Mixture:
Add in the salt, pepper, and, if you like, garlic powder and paprika for added flavor. Stir until everything is evenly seasoned.
5. Pour into Baking Dish:
Transfer the mixture into the greased baking dish. Use a spatula to spread it out evenly, ensuring an even bake.
6. Prepare the Topping:
In a small bowl, mix the crushed buttery crackers with melted butter. This will create a tasty, crispy topping. Sprinkle this mixture evenly over the squash mixture in the baking dish.
7. Bake the Casserole:
Place the baking dish in the preheated oven and bake for 30-35 minutes. You’ll know it’s ready when the top is golden brown and bubbly.
8. Serve and Enjoy:
Once it’s done, remove the casserole from the oven and let it sit for a few minutes before serving. This will help the dish set a little. Then, portion it out and enjoy this creamy, cheesy Southern classic as a delightful side!
