Key Ingredients & Substitutions
Yellow Squash: Fresh squash gives this dish its essential taste. If you can’t find yellow squash, zucchini works well too! Just make sure to slice it thin for even cooking.
Onions: The base flavor comes from chopped onions. If you want something milder, try using shallots or green onions for a different taste.
Cheddar Cheese: Sharp cheddar is my top choice for a flavor kick. You can substitute with mild cheddar or even a pepper jack if you’re up for some heat.
Mayonnaise & Sour Cream: These add creaminess. Greek yogurt makes a nice substitute if you want a healthier option. Just keep the flavor consistent!
Crushed Crackers: Butter crackers like Ritz provide a great topping crunch. If you need a gluten-free version, you can use gluten-free crackers or even breadcrumbs.
How Do You Properly Cook the Squash for Casserole?
Cooking the squash before mixing it helps remove excess moisture, which prevents a soggy casserole. Here’s how to do it:
- Bring a large pot of water to a boil and add the sliced squash.
- Cook for about 5 minutes until the squash is tender but not mushy.
- Drain thoroughly to remove as much water as possible, then transfer to a mixing bowl to continue preparing your casserole.
By following this step, your casserole will have the perfect consistency and taste! Enjoy making this comforting dish!
Classic Southern Squash Casserole
Ingredients You’ll Need:
- 4 cups yellow squash, sliced (about 4 medium squash)
- 1 cup onion, finely chopped
- 1 cup shredded sharp cheddar cheese
- 3 large eggs, beaten
- 1/2 cup mayonnaise
- 1/2 cup sour cream
- 1 cup crushed buttery crackers (like Ritz)
- 4 tablespoons butter, melted
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder (optional)
How Much Time Will You Need?
This delicious casserole will take about 15 minutes to prepare and 40 to 45 minutes to bake, making the total time around 1 hour. You’ll have a bubbling, cheesy delight ready to enjoy in no time!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This gives it time to get nice and hot while you prep the other ingredients. Don’t forget to lightly grease your 2-quart casserole dish to prevent sticking!
2. Prepare the Squash:
In a large pot, bring water to a boil. Once it’s boiling, add the sliced yellow squash and cook for about 5 minutes, just until they are tender. Drain the squash well, and then transfer it to a large mixing bowl. This step helps to remove excess moisture, so your casserole doesn’t become soggy.
3. Mix All the Ingredients:
To the bowl with the cooked squash, add the finely chopped onions, shredded cheddar cheese, beaten eggs, mayonnaise, sour cream, salt, pepper, and garlic powder (if you’re using it). Stir everything together until well combined—this will make for a creamy, flavorful filling.
4. Transfer to Casserole Dish:
Pour your mixed squash filling into the greased casserole dish. Use a spatula to smooth the top evenly, so it cooks uniformly.
5. Prepare the Topping:
In a small bowl, mix the crushed buttery crackers with the melted butter. Stir until the crumbs are evenly coated, then sprinkle this mixture generously over the squash mixture in the casserole dish. This will create a delicious, crunchy topping that adds texture.
6. Bake the Casserole:
Place the casserole in the preheated oven and bake uncovered for 40 to 45 minutes. You’ll know it’s done when the casserole is bubbly and the topping is golden brown. Keep an eye on it, so it doesn’t over-brown!
7. Serve and Enjoy:
Once it’s out of the oven, let the casserole cool for a few minutes. This makes it easier to serve and helps bring out the flavors. Then, dig in and enjoy this comforting Southern classic alongside your favorite main dishes!
Can I Use Other Types of Squash?
Absolutely! While yellow squash is traditional, zucchini can also be used as a substitute. Just be sure to slice it thinly and pre-cook as directed for the right texture.
How Can I Make This Recipe Ahead of Time?
You can prepare the casserole up to the baking step and cover it tightly with plastic wrap or aluminum foil. Refrigerate for up to 24 hours. When you’re ready to bake, simply add about 10 extra minutes to the baking time if it’s cold from the fridge.
What’s the Best Way to Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place it in the oven at 350°F (175°C) until warmed through, or microwaving in individual portions works well too!
Can I Freeze This Casserole?
Yes! This casserole freezes well. After baking, let it cool completely, then wrap it tightly in foil and place it in an airtight container. It can be frozen for up to 3 months. Thaw overnight in the fridge before reheating.
