How to Make Cheesy Southern Squash Casserole

Now that you’ve gathered your ingredients, it’s time to roll up those sleeves and get cooking! Making this Cheesy Southern Squash Casserole is a delightful journey. Follow these step-by-step instructions for a simple and scrumptious dish your whole family will love.

Step 1: Prepare the Squash and Onion Mixture

Start by slicing the fresh squash into even 6 mm rounds. This helps them cook uniformly. In a large mixing bowl, combine the drained squash, chopped onion, garlic powder, salt, black pepper, sour cream, beaten egg, shredded cheddar cheese, and 25 grams of Parmesan cheese. Give it a good stir until everything is nicely blended.

Step 2: Mix the Cracker Topping

In another bowl, melt 45 millilitres of butter. Next, toss in the finely crushed butter crackers along with the remaining 25 grams of Parmesan cheese. Stir until each cracker is well-coated. This will give your casserole that lovely crunchy topping we all crave!

Step 3: Sauté the Onion for Flavor

Set a large pan on medium heat and melt 15 millilitres of butter. Add the chopped onion and sauté for about 7 to 8 minutes. You’re looking for that perfect golden-brown hue and a soft, translucent texture. This step really enhances the flavors in the Cheesy Southern Squash Casserole.

Step 4: Cook the Squash until Soft

Once your onions are sautéed, added the sliced squash to the pan. Cook for about 10 to 12 minutes, stirring often until the squash softens and some moisture evaporates. Don’t rush this step; it’s essential for making sure your casserole doesn’t turn soggy!

Step 5: Combine Ingredients in Baking Dish

Now it’s time to bring everything together! Carefully scoop the squash mixture into a 1.5-litre baking dish. Spread it out evenly to ensure an even cook. Then, sprinkle that gorgeous cracker mixture on top to create a delicious crust.

Step 6: Drain Excess Moisture

To keep your casserole from becoming too moist, place the squash and onion mix into a colander lined with a clean kitchen towel. Let it drain for at least 5 minutes, gently pressing to remove any excess liquid. This is a crucial step for a successful casserole!

Step 7: Bake the Casserole

Preheat your oven to 175°C (350°F). Slide that loaded dish into the oven and bake for about 25 minutes, or until the top is golden and bubbly. Once it’s out, let it cool for just a couple of minutes before serving. Your Cheesy Southern Squash Casserole is ready to shine on your table!

Tips for Success

Large pan: An ordinary skillet or frying pan will do just fine for sautéing.

Measuring cups and spoons: Handy for precise measurements, but you can use your everyday kitchen tools if needed.
