This Easy Yellow Squash Casserole is a warm, tasty dish that brings out the best in summer squash. With a creamy filling and a crunchy topping, it’s simply yummy!
Key Ingredients & Substitutions
Yellow Squash: This is the star of the dish! Look for firm, blemish-free squash. If yellow squash is unavailable, zucchini works well as a substitute.
Onion: You can use yellow or white onion for their sweetness. If you need a milder flavor, try using a shallot or green onions instead.
Cheddar Cheese: I love sharp cheddar for its bold flavor. Mild cheddar or even a blend of cheeses like mozzarella or Monterey Jack can be nice alternatives!
Sour Cream and Mayonnaise: Greek yogurt can replace sour cream for a healthier option without sacrificing creaminess. You could omit mayonnaise, but it adds great moisture.
Crackers: For a gluten-free option, try crushed gluten-free crackers or use almond flour mixed with some melted butter. It won’t have the same texture, but it works!
How Do I Ensure the Squash Isn’t Watery?
A common issue with casseroles is excess moisture. Here’s how to manage it:
- Always drain the cooked squash well to remove excess water.
- Consider salting the slices before cooking. Let them sit for 10 minutes and then pat dry with paper towels.
- Don’t skip baking uncovered – this allows steam to escape and keeps the casserole from getting soggy.
Following these tips will give you a firm and flavorful casserole that everyone will love!
Easy Yellow Squash Casserole
Ingredients:
- 4 cups yellow squash, sliced
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 cup shredded cheddar cheese
- 1 cup sour cream
- 1/2 cup mayonnaise
- 2 large eggs, beaten
- 1 cup crushed buttery crackers (such as Ritz)
- 1/4 cup butter, melted
- 1/4 teaspoon black pepper
- 1/2 teaspoon salt
- 1/2 teaspoon dried thyme or parsley (optional)
Time Needed:
This delicious casserole will take about 15 minutes to prep and around 35-40 minutes to bake. Allow an additional few minutes for cooling before serving. In total, you’re looking at approximately 1 hour to have this dish ready to enjoy!
Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While it’s heating up, grease a 9×13 inch baking dish to prevent sticking.
2. Prepare the Squash:
In a large pot, bring water to a boil. Once boiling, add the sliced yellow squash and cook for about 3-4 minutes, just until tender but not mushy. Drain the squash and set it aside to cool slightly.
3. Sauté the Aromatics:
In a skillet over medium heat, add a little butter or oil and sauté the chopped onion and minced garlic until they’re softened, which should take about 3-4 minutes. This will add great flavor to your casserole!
4. Mix the Filling:
In a large mixing bowl, combine the cooked squash, sautéed onions and garlic, shredded cheddar cheese, sour cream, mayonnaise, beaten eggs, salt, black pepper, and the optional thyme or parsley. Stir everything together until well mixed.
5. Assemble the Casserole:
Pour the squash mixture into your greased baking dish, spreading it out evenly. This is going to be a flavorful base for your casserole!
6. Add the Crunchy Topping:
In a small bowl, mix the crushed crackers with melted butter. Sprinkle this mixture evenly over the top of the squash filling. This will give your casserole a delightful crunchy texture!
7. Bake It:
Place the baking dish in the preheated oven and bake uncovered for 35-40 minutes or until the casserole is set and the cracker topping is golden brown.
8. Cool and Serve:
Once it’s baked, take the casserole out and let it cool for a few minutes before digging in. This allows the flavors to settle and makes serving easier!
Enjoy your delicious, creamy, and crunchy Easy Yellow Squash Casserole! It’s perfect as a side dish for any meal or a wonderful vegetarian entree!
Can I Use Different Types of Squash?
Absolutely! While yellow squash is the star of this recipe, zucchini works wonderfully as a substitute. You can even combine both for a colorful twist.
How Can I Make This Casserole Healthier?
To lighten it up, use low-fat sour cream and mayonnaise, or substitute Greek yogurt for the sour cream. You can also reduce the amount of cheese or use a low-fat cheese option.
Can I Prepare This Casserole in Advance?
Yes! You can prepare the casserole a day ahead of time. Just cover it and refrigerate before baking. When you’re ready to bake, you might need to add an extra few minutes to the cooking time since it will be cold from the fridge.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm it in the oven at 350°F (175°C) until heated through, or microwave in individual portions until hot.
