How to Make Cheesy Squash Casserole
Creating a Cheesy Squash Casserole is a straightforward process that anyone can master. Follow these simple steps, and you’ll have a delicious dish ready to impress your family or friends.
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Preheating is crucial because it ensures even cooking. You want that casserole to bake perfectly, so don’t skip this step!
Step 2: Sauté the Onions
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté for about 3 minutes until it becomes translucent. This step enhances the flavor, making your casserole even more delicious. The sweet aroma of sautéing onions is a sure sign you’re on the right track!
Step 3: Cook the Squash and Zucchini
Next, toss in the sliced yellow squash and zucchini. Season them with salt, pepper, and garlic powder. Cook for about 5-7 minutes until the vegetables are tender but still have a bit of bite. You want them to retain their shape and not turn mushy. This is where the magic begins!
Step 4: Mix the Egg and Cheese Base
In a large mixing bowl, combine the beaten eggs, milk, and half of the shredded cheddar cheese. Stir until well blended. This mixture will create a creamy texture that binds everything together, making each bite a cheesy delight.
Step 5: Combine Ingredients
Now, fold the sautéed vegetables into the egg and cheese mixture. In a separate bowl, mix the crushed buttery crackers and Parmesan cheese. Reserve half of this mixture for topping the casserole. Fold the remaining cracker mixture into the vegetable and egg mixture until everything is well combined.
Step 6: Prepare the Baking Dish
Grease a 9×13-inch baking dish with a bit of olive oil or cooking spray. Pour the combined mixture into the dish, spreading it evenly. This ensures that every bite is packed with flavor and goodness.
Step 7: Bake the Casserole
Place the dish in the preheated oven and bake for 25-30 minutes. Keep an eye on it! You’ll know it’s done when the top is golden brown and bubbly. That’s the sign of a perfectly baked Cheesy Squash Casserole!
Step 8: Cool and Serve
Once it’s out of the oven, let the casserole cool for about 5 minutes before serving. This brief cooling period allows the flavors to settle and makes it easier to cut into portions. Trust me, the wait will be worth it!

Tips for Success
- Use fresh vegetables for the best flavor and texture.
- Don’t rush the sautéing process; it builds a rich base.

Equipment Needed
- Large Skillet: A non-stick skillet works best, but any large pan will do.

- Baking Dish: A 9×13-inch dish is ideal; a similar-sized casserole dish can substitute.
- Spatula: A rubber spatula helps in folding ingredients without damaging them.
