Step‑by‑Step Instructions for Cheesy Yellow Squash Casserole
Step 1: Preheat Your Oven
Begin your culinary adventure by preheating your oven to 350°F (175°C). This crucial step ensures that your Cheesy Yellow Squash Casserole cooks evenly and thoroughly. While the oven warms up, gather your ingredients and prepare your workspace so that everything is within arm’s reach for a smooth cooking experience.
Step 2: Mix the Casserole Ingredients
In a large bowl, combine 4 cups of sliced yellow squash, 1 cup of shredded cheddar cheese, 1/2 cup of sour cream, 1/2 cup of milk, 1/4 cup of chopped onions, and a sprinkle of salt and pepper. Stir the mixture well until all ingredients are evenly coated. You want to see creamy, cheesy goodness enveloping your fresh squash.
Step 3: Prepare the Baking Dish
Next, take a greased 9×13 inch baking dish and carefully transfer the squash mixture into it. Spreading it evenly across the dish is essential, as it ensures even cooking and melty cheese distribution. Make sure to smooth the top with a spatula so that it looks inviting before adding the topping.
Step 4: Create the Crunchy Topping
In a separate bowl, mix together 1/2 cup of breadcrumbs, 1/4 cup of grated Parmesan cheese, and 2 tablespoons of melted butter. Stir until the breadcrumbs are well combined and coated with butter, creating a rustic, crispy texture. This crunchy topping will add an irresistible contrast to the creamy flavors of your Cheesy Yellow Squash Casserole.
Step 5: Sprinkle and Bake
Evenly sprinkle the breadcrumb mixture over the top of the squash mixture, allowing it to cover every inch. Place the baking dish in the preheated oven and bake for 30 to 35 minutes. You’ll know it’s ready when the top is golden brown and the squash is tender; a gentle poke with a fork should easily break through the layers.
Step 6: Cool and Serve
Once baked to perfection, take your Cheesy Yellow Squash Casserole out of the oven and let it cool for a few minutes. This resting time allows the flavors to meld and makes slicing easier. After cooling slightly, serve warm and enjoy the delightful blend of creamy and crunchy textures that this comforting dish has to offer!

Cheesy Yellow Squash Casserole Recipe FAQs
What type of yellow squash should I use for the casserole?
Absolutely! Look for firm, bright yellow squash without any dark spots or soft areas. This ensures that your Cheesy Yellow Squash Casserole has the best flavor and texture. You can also substitute with zucchini if you prefer a slightly different taste, or even mix both for added color and nutrition.
How long can I store leftovers of the casserole?
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Be sure the casserole has cooled completely before sealing to maintain its freshness and prevent sogginess as you store it.
Can I freeze Cheesy Yellow Squash Casserole?
Definitely! To freeze your casserole, wrap it tightly in plastic wrap, followed by aluminum foil, to prevent freezer burn. It will keep well for up to 3 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and reheat in the oven at 350°F (175°C) for about 20 minutes until heated through.
What should I do if my casserole turns out watery?
If you find that your Cheesy Yellow Squash Casserole seems watery, this typically happens with older or overripe squash. To avoid this, I recommend slicing the squash and letting it sit with a sprinkle of salt for about 15 minutes before mixing it into the casserole. This draws out excess moisture so that you’re left with a creamy texture rather than a soggy one.
Are there any dietary considerations I should be aware of?
Very! This casserole is vegetarian-friendly and can easily be made gluten-free by using gluten-free breadcrumbs. If you have lactose intolerance, feel free to swap the sour cream and milk for dairy-free alternatives, such as Greek yogurt and almond milk. Always double-check ingredient labels to avoid any known allergens.
Can I make the casserole ahead of time?
Yes, absolutely! This is a fantastic make-ahead dish. Assemble the casserole a day in advance, cover it, and refrigerate it. When you’re ready to bake, just pop it in the oven. This not only saves you time but also helps the flavors to meld beautifully!
