Gathering Ingredients for a Perfect Sour Cream Squash Casserole
When I’m making my sour cream squash casserole, I always pick the freshest squash. Look for firm, bright yellow ones. For the sour cream, I usually go for full-fat.

Making this sour cream squash casserole is straightforward. I promise! Just follow these simple steps. You’ll have a delicious side dish in no time. I’ve broken it down for you. This makes it super easy to follow along. You will love how quickly it all comes together. Let’s get started on this creamy delight.
Preparing Your Sour Cream Squash Casserole with Ease
First, preheat your oven to 375°F (190°C). This gets it ready for baking. Next, you need to cook your sliced yellow squash. I usually steam mine. You can boil it too. Cook it until it’s tender. This takes about 10-15 minutes. The crucial part here is draining it really well. No one likes a watery casserole! After draining, mash the cooked squash in a large bowl. I use a potato masher for this. It works perfectly.
Baking Your Golden Sour Cream Squash Casserole
Now, let’s get that amazing flavor going. Stir in the sour cream with your mashed squash. Add the cheddar cheese, chopped onion, salt, black pepper, and garlic powder. Mix everything until it’s fully combined. Pour this mixture into a 9×13 inch baking dish. For the topping, combine the breadcrumbs and melted butter in a small bowl. Sprinkle this evenly over the squash mixture. Bake for 25-30 minutes. It’s ready when it’s golden brown and bubbly. Serve it hot and enjoy!

My goal is always to help you create something truly special. So, here are my best secrets. They will ensure your casserole is absolutely perfect.
Making Your Sour Cream Squash Casserole Shine
For the creamiest texture, I always recommend full-fat sour cream. It just makes it so rich. If you like a little heat, add a tiny pinch of cayenne pepper. It won’t make it spicy. It simply adds a lovely warmth. Don’t forget to really drain your squash well. This prevents a watery casserole. These small steps make a big difference.
Serving and Storing Your Sour Cream Squash Casserole
Once your sour cream squash casserole is golden and bubbly, it’s ready! I love to serve it right from the oven. It’s perfect as a side dish for almost any meal.
