Ingredients:

• 2 pounds yellow squash (sliced ¼ inch thick (about 5 medium sized squash))
• 1/4 cup butter
• 1/2 cup diced onion
• 1/2 teaspoon garlic powder
• 3/4 teaspoon salt
• 1/2 teaspoon black pepper
• ½ cup sour cream
• 1 large egg (beaten)
• 1 cup shredded cheddar cheese
• ½ cup grated Parmesan cheese
• 1 cup butter crackers (finely crushed ( about 25 crackers ))

Cooking Instructions

1.

Prepping the Squash and Aromatics

The first step in creating our delicious squash casserole is to prepare the star ingredient: the yellow squash. Make sure to wash your squash thoroughly. We want to slice them about ¼ inch thick. This thickness is crucial; too thin and they might turn to mush, too thick and they might not cook through evenly. Once sliced, you can set them aside for now. Next, let’s get our flavor base started. In a large skillet, melt the 1/4 cup of butter over medium heat. Once the butter is melted and slightly shimmering, add the 1/2 cup of diced onion. We want to sauté these onions until they become translucent and tender, which usually takes about 5-7 minutes. This process brings out their sweetness and mellows their bite. Don’t rush this step; it builds a foundational layer of flavor for the entire casserole.

2.

Cooking the Squash

Once the onions are softened, add the sliced yellow squash to the skillet. We’re not trying to fully cook the squash at this stage, but rather to par-cook them and remove some excess moisture. Add the 1/2 teaspoon of garlic powder, 3/4 teaspoon of salt, and 1/2 teaspoon of black pepper to the skillet with the squash and onions. Stir everything together to ensure the seasonings are evenly distributed. Cook the squash, stirring occasionally, for about 8-10 minutes. You’ll notice the squash starting to soften and release some of its liquid. We want it tender-crisp, not mushy. If there seems to be a lot of liquid in the pan, you can carefully drain off any excess before proceeding. This step is important for preventing a watery casserole.

3.

Creating the Creamy Sauce

Now it’s time to bring the creamy goodness to our casserole. In a medium bowl, combine the 1/2 cup of sour cream and the 1 large beaten egg. Whisk these two ingredients together until they are well combined and smooth. This mixture will act as the binder for our casserole, creating a rich and luxurious sauce. Once the squash and onion mixture has cooled slightly in the skillet (you don’t want to scramble the egg!), gently fold the sour cream and egg mixture into the squash. Add the 1 cup of shredded cheddar cheese and the 1/2 cup of grated Parmesan cheese to the bowl with the squash. Stir everything together gently until all the ingredients are evenly incorporated and coated. The cheese will start to melt slightly from the residual heat of the squash, creating a beautiful, cohesive mixture.

4.

Assembling and Topping the Casserole

Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). While the oven is preheating, lightly grease a 9×13 inch baking dish. Spoon the squash mixture evenly into the prepared baking dish, spreading it out so it forms an even layer. Now for that irresistible crunch! In a separate small bowl, combine the 1 cup of finely crushed butter crackers with about 1 tablespoon of melted butter (you can melt a little extra butter if needed, or use some from the initial step). Sprinkle this buttery cracker crumb mixture evenly over the top of the squash casserole. This topping will bake up into a golden-brown, crispy layer that is absolutely divine. Ensure the entire surface is covered for maximum crunch.

5.

Baking to Perfection

Place the assembled casserole into the preheated oven. Bake for 25-30 minutes, or until the casserole is heated through, bubbly around the edges, and the cracker topping is golden brown and deliciously crisp. Keep an eye on it during the last 10 minutes of baking to ensure the topping doesn’t get too dark. If it’s browning too quickly, you can loosely tent the dish with aluminum foil. Once baked to perfection, carefully remove the casserole from the oven. Let it rest for about 5-10 minutes before serving. This resting period allows the casserole to set up slightly, making it easier to serve and ensuring all those wonderful flavors meld together. Serve hot and enjoy the applause!
