Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the Casserole:

4 cups yellow squash, sliced (about 1–1.5 lbs)
1 small onion, finely chopped
2 tablespoons butter
2 large eggs, lightly beaten
1 cup shredded sharp cheddar cheese
1 cup sour cream
1/2 cup mayonnaise
1 teaspoon salt
1/2 teaspoon black pepper

For the Topping:

1 sleeve buttery crackers (such as Ritz), crushed (about 1 1/2 cups)
1/4 cup grated Parmesan cheese
4 tablespoons melted butter

Directions

Cook the Squash: I bring a large pot of salted water to a boil, add the sliced squash, and cook for 5–7 minutes until tender but not mushy. After draining, I let it cool slightly and gently press out excess moisture to prevent a watery casserole.
Sauté the Onions: In a skillet over medium heat, I melt 2 tablespoons of butter, add the chopped onion, and sauté for 3–4 minutes until soft and translucent. I then set it aside.
Make the Filling: In a large mixing bowl, I combine the cooked squash, sautéed onions, beaten eggs, shredded cheddar cheese, sour cream, mayonnaise, salt, and black pepper. I mix everything well until evenly combined.
Prepare the Topping: In a separate bowl, I mix the crushed buttery crackers, grated Parmesan cheese, and melted butter until the crumbs are evenly coated.
Assemble the Casserole: I preheat the oven to 350°F (175°C), transfer the squash mixture into a greased 9×13-inch baking dish, and spread it evenly. Then, I sprinkle the cracker topping over the casserole.
Bake: I bake the casserole for 30 minutes covered with foil to prevent the topping from burning. Then, I uncover it and bake for an additional 15–20 minutes until the top is golden brown and the casserole is bubbly.

Servings and Timing

This recipe yields approximately 8 servings. The total preparation time is about 20 minutes, with a cook time of 45–50 minutes, making it a perfect dish to prepare ahead of time for gatherings.

Variations

Add Protein: Sometimes, I add cooked, chopped chicken or turkey to make it a more substantial main dish.
Spice It Up: For a bit of heat, I include a dash of cayenne pepper or chopped jalapeños.
Herbaceous Twist: Fresh herbs like thyme or parsley can add a refreshing flavor.

Storage and Reheating

I store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, I cover the casserole with foil and warm it in a 350°F (175°C) oven until heated through. Alternatively, individual portions can be microwaved for 1–2 minutes.

FAQs

How can I prevent the casserole from becoming watery?

I make sure to drain the cooked squash thoroughly and press out any excess moisture before mixing it with the other ingredients.

Can I prepare this casserole ahead of time?

Yes, I often assemble the casserole a day in advance, cover it tightly, and refrigerate it. I add the topping just before baking.

Is it possible to freeze this casserole?

Absolutely. I assemble the casserole without the topping, wrap it well, and freeze it. When ready to bake, I thaw it overnight in the refrigerator, add the topping, and bake as directed.

Can I use a different type of squash?

Yes, zucchini works well as a substitute or in combination with yellow squash.

What can I serve with this casserole?

I like to pair it with grilled meats, a fresh green salad, or roasted vegetables for a complete meal.
