Step-by-Step Recipe Instructions

1. Preparing the Ingredients

Begin by preheating your oven to 350°F (175°C). Grease a 2-quart casserole dish with butter or non-stick spray. Gather all your ingredients, ensuring they’re measured and ready to go. Proper preparation is key to a smooth cooking process.

2. Cooking the Squash and Onion

In a large skillet, melt 3 tablespoons of butter over medium-high heat. Add the sliced yellow squash and chopped onion, seasoning with salt and pepper. Sauté the vegetables until the squash is tender, about 10 minutes. Transfer the mixture to a colander to drain any excess liquid, which prevents the casserole from becoming watery.

3. Making the Casserole Filling

In a large mixing bowl, whisk together the eggs, sour cream, Cheddar cheese, Swiss cheese, and milk. Season with salt, pepper, and a pinch of thyme if desired. Gently fold in the drained squash and onion mixture, ensuring everything is well combined.

4. Assembling the Casserole

Spoon the squash mixture into the prepared casserole dish. In a separate bowl, mix the crushed Ritz crackers with melted butter and Parmesan cheese. Sprinkle this mixture evenly over the top of the casserole.

5. Baking the Casserole

Bake the casserole uncovered in the preheated oven for about 30 minutes, or until the top is golden brown and the casserole is bubbling around the edges. Allow the casserole to cool for a few minutes before serving, which helps the dish set and makes it easier to slice.

Tips for the Best Squash Casserole

Achieving the perfect Squash Casserole requires attention to detail and a few essential tips:

Drain the Squash Thoroughly: Properly draining the sautéed squash and onions is crucial to avoiding a watery casserole. Let the vegetables sit in a colander for several minutes to remove excess moisture.
Use Fresh Cheese: Freshly grated cheese melts more smoothly and provides a better flavor than pre-shredded cheese, which often contains anti-caking agents.
Don’t Overcook the Squash: Sauté the squash just until tender. Overcooking can result in a mushy texture that detracts from the dish.
