Step‑by‑Step Instructions for Cozy Southern Squash Casserole with Cheese
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms, take a 2-quart baking dish and generously grease it with cooking spray or a pat of butter, ensuring the final product won’t stick. This step is crucial for easy serving later on!
Step 2: Prepare Squash and Onion
In a large pot, bring water to a boil, then add your sliced yellow squash and chopped onion. Let them cook for about 5 minutes until they soften but retain some texture. Once tender, drain the vegetables thoroughly and allow them to cool slightly, keeping the flavors vibrant for your Cozy Southern Squash Casserole.
Step 3: Mix Ingredients
In a spacious mixing bowl, combine the cooled squash and onion with cheddar cheese, crushed buttery crackers, milk, eggs, melted butter, and all the seasonings. Mix thoroughly until every ingredient is well incorporated, creating a rich and creamy base that embodies the essence of Southern comfort.
Step 4: Bake Casserole
Pour the fluffy mixture into your pre-greased baking dish, spreading it evenly across the surface. Place the dish in the preheated oven and bake for 30-35 minutes. Look for a golden-brown top, and ensure the casserole is set in the center—this is when it’s at its savory best!
Step 5: Serve
Once baked, remove your Cozy Southern Squash Casserole from the oven and let it cool for about 5 minutes. This short resting time allows the flavors to meld beautifully. Then, slice it up and serve warm, letting the delightful aroma fill your home as you enjoy this comforting dish with loved ones.
