Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash gives this dish its vibrant color and mild flavor. If you can’t find yellow squash, zucchini works well as a substitute.
Onion: Using finely chopped onion adds a nice flavor boost. If you’re not a fan of onions, you can omit them or use minced green onions instead.
Cheddar Cheese: I love sharp cheddar for its strong flavor, but feel free to use mild cheddar or a blend of cheeses like Monterey Jack and mozzarella for a creamier texture.
Sour Cream & Mayonnaise: These ingredients provide creaminess. Greek yogurt can be a healthier substitute for sour cream; use it in the same amount. If you prefer, you can use all sour cream instead of mayo.
Crackers: I like using Ritz crackers for their buttery taste, but any crispy cracker will do! Gluten-free crackers work great if you need a gluten-free option.
How Do I Make Sure My Casserole Stays Creamy and Doesn’t Get Watery?
It’s important to properly prepare your squash to avoid excess moisture in your casserole. Here’s how:
- Start by cooking the squash and onion briefly to soften them. This step helps release some moisture.
- Drain the cooked squash well to remove as much water as you can. Squeezing it in a clean towel can help too.
- Mix your squash with the creamy ingredients right away while they’re still warm. This helps everything blend nicely.
Following these steps will help keep your casserole creamy and delicious. Enjoy making your dish!
Easy Yellow Squash Casserole
Ingredients You’ll Need:
For the Casserole:
- 4 cups yellow squash, sliced
- 1/2 cup onion, finely chopped
- 1 cup shredded cheddar cheese
- 1 cup sour cream
- 1/2 cup mayonnaise
- 2 large eggs, beaten
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon garlic powder (optional)
For the Topping:
- 1 cup crackers, crushed (such as Ritz or buttery crackers)
- 3 tablespoons butter, melted
How Much Time Will You Need?
The total time to prepare and bake this delicious casserole is about 50 minutes. You’ll spend around 15 minutes prepping the ingredients and about 35 minutes baking it until golden and bubbly. A quick, delightful dish that everyone will love!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This ensures it will be hot and ready when you’re done mixing the ingredients.
2. Cook the Squash and Onions:
In a large pot, bring salted water to a boil. Once it’s boiling, add in the sliced yellow squash and chopped onions. Cook for about 5 minutes, or until they are tender but not mushy. Drain them well and set them aside to cool a bit.
3. Make the Casserole Mixture:
In a large mixing bowl, combine the drained squash and onions with sour cream, mayonnaise, beaten eggs, shredded cheddar cheese, salt, pepper, and garlic powder (if you’re using it). Stir everything together until it’s combined nicely and creamy.
4. Assemble the Casserole:
Pour the squash mixture into a greased 9×13 inch baking dish. Spread it evenly so it cooks evenly.
5. Prepare the Cracker Topping:
In a small separate bowl, mix the crushed crackers with melted butter, making sure each piece is evenly coated. This will create a delicious, crunchy topping.
6. Top and Bake:
Sprinkle the buttery cracker mixture evenly over the squash casserole. Bake in the preheated oven for 30-35 minutes, or until the cheese is melted, and the topping is golden brown and crispy.
7. Serve and Enjoy:
Once out of the oven, let the casserole cool for a few minutes before serving. This hearty and easy yellow squash casserole is perfect as a side dish or even a main meal. Enjoy!
Can I Use Different Types of Squash?
Yes! While yellow squash is traditional for this casserole, you can use zucchini or a mix of both for added flavor and variety. Just ensure you slice them thinly for even cooking.
Can I Prepare This Casserole in Advance?
Absolutely! You can prepare the casserole mixture a day ahead. Store it in the refrigerator, and when you’re ready to bake, simply add the cracker topping and bake as directed. It’s a great time-saver!
How Should I Store Leftovers?
Leftover casserole can be stored in an airtight container in the fridge for up to 3 days. To reheat, place it in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through. You can also microwave individual portions for a quick meal!
Can I Make This Casserole Healthier?
Yes! You can reduce the calories by using low-fat sour cream and mayonnaise. Additionally, you can substitute the crackers with a whole-grain option or even crushed nuts for a healthier twist on the topping.
