Step‑by‑Step Instructions for Squash Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grab a 9×13 inch baking dish and generously grease it with butter or cooking spray, creating a non-stick surface for your delicious squash casserole.
Step 2: Cook the Squash
In a large pot, bring water to a boil and add your sliced squash. Allow it to cook for 8–10 minutes until the squash is fork-tender but not mushy. Once done, drain the squash well to eliminate excess moisture; this prevents your casserole from becoming watery.
Step 3: Mix the Ingredients
In a large mixing bowl, combine the drained squash with melted butter, sour cream, shredded cheddar cheese, and finely chopped onion. Season with salt and pepper to taste. Stir the mixture thoroughly until all the ingredients are blended well for a creamy consistency that forms the heart of your squash casserole.
Step 4: Assemble the Casserole
Transfer the squash mixture into your prepared baking dish, smoothing it out evenly with a spatula. This layering ensures that every bite of the casserole will be packed with flavor and creaminess, setting the stage for the delicious toppings to come.
Step 5: Add the Topping
Sprinkle the crushed crackers evenly over the top of your squash mixture. This will create a lovely golden crust as it bakes, adding texture and crunch that beautifully contrasts with the creamy filling of your squash casserole.
Step 6: Bake the Casserole
Place the baking dish in your preheated oven and bake for 25–30 minutes. Keep an eye on it; the casserole is ready when it’s bubbly and the top is a lovely golden brown, creating an inviting visual that will draw everyone to the table.
Step 7: Rest Before Serving
After baking, remove the squash casserole from the oven and allow it to rest for about 5-10 minutes. This brief cooling time helps the casserole set up and makes serving easier, ensuring you can scoop out perfect portions filled with creamy goodness and crispy topping.
