Ingredients

Fresh summer squash, cheese, eggs, and other essentials for squash casserole.

Now, let’s talk about what you’ll need for this comforting squash casserole dish. I always aim for fresh, quality produce because it truly shines through in the final dish. Here’s my ingredient list to get your squash bake recipe started:

  • 4 cups summer squash, sliced thin (I prefer a mix of yellow and zucchini for that beautiful color contrast)
  • 1 medium onion, finely chopped
  • 2 large eggs
  • 1 cup sour cream (this gives the casserole that creamy, rich texture)
  • 1 cup shredded cheddar cheese (sharp cheddar works best for my squash casserole)
  • 1 cup breadcrumbs (crunchy topping is crucial; sometimes I use panko for extra crispness)
  • 1/2 cup melted butter
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder

I always use fresh summer squash straight from the market when I can find it, but frozen slices thawed and drained can work if you’re short on time. When shopping for ingredients for squash casserole, check your local farmer’s market for excellent summer squash—sometimes they’re cheaper there, especially during peak season. And if you want a twist, try buying already shredded cheese to save time. Here’s a little kitchen wisdom: draining your squash well before mixing is a must to prevent a watery soupy mess.

For dressing up your squash bake recipe with extra flavor, sometimes I swap out regular sour cream for creamed yellow squash blends or add a pinch of smoked paprika. When you’re buying breadcrumbs, you might find seasoned ones that add a little extra pop. All leftovers store beautifully—refrigerate any unused sour cream in airtight containers for up to a week, and keep your cheese sealed tight so it stays fresh.

How to Make – Step-by-Step

Okay love, here’s where the magic happens. I’m going to walk you through my favorite way to make this classic squash casserole—a squash bake recipe that has truly stood the test of time in my kitchen. You’ll see, it’s not intimidating at all!

  1. Prep the squash: Start by slicing 4 cups of summer squash thinly. I like combining yellow squash and zucchini for color and flavor. Here’s a tip I learned from my mom: sprinkle the slices with salt and let them sit in a colander for about 20 minutes to draw out excess moisture. Then, gently squeeze to remove extra water—this keeps your squash casserole from being soggy.
  2. Sauté onions: While the squash is draining, soften one finely chopped medium onion in a skillet with a bit of butter until translucent and fragrant. This step adds a lovely sweetness to your squash casserole.
  3. Mix the base: In a large bowl, beat 2 eggs lightly, then stir in 1 cup sour cream, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1/2 teaspoon garlic powder. You can also fold in your creamed yellow squash here if you like that extra richness.
  4. Combine squash and onions: Add the drained squash and cooked onions to your sour cream mixture then mix gently until everything is well coated.
  5. Add cheese: Stir in 1 cup shredded sharp cheddar cheese. I’ve found that sharper cheese balances out the sweetness of the summer squash perfectly.
  6. Transfer to baking dish: Pour the mixture into a greased 9×13-inch baking dish, smoothing the top.
  7. Prepare topping: Mix 1 cup breadcrumbs with 1/2 cup melted butter, then sprinkle evenly over your squash casserole.
  8. Bake: Pop your casserole into a preheated oven at 350°F (175°C) for about 40-45 minutes. You want the top golden brown and crispy, and the casserole bubbly around the edges.
  9. Cool slightly before serving: This helps the casserole set and makes it easier to cut nicely.

Don’t worry if your squash casserole looks a little watery before baking—that’s totally normal! The magic happens as it bakes, and that crunchy breadcrumb topping seals it all in. In my kitchen, this squash bake recipe usually takes about an hour from start to finish, but feel free to multi-task—while the squash casserole is in the oven, I like to prep a quick side salad or catch up on emails.

If you run into any troubles or want to see step-by-step visuals, there’s a great southern squash casserole guide over at Basil And Bubbly that helped me polish my technique. Another gem for troubleshooting and tips is the Just A Pinch Facebook community post where cooks share their souvenirs and tweaks.

Southern squash casserole shines at holiday dinners and summer barbecues alike. It’s the perfect side dish for a potluck because it travels well and pleases even the pickiest eaters—you might be surprised how your guests’ll ask for seconds! On casual nights, I’ll serve it alongside a crusty bread and a simple green vegetable to keep things fresh.

FAQs

Q1: Can I make squash casserole ahead of time?
Absolutely! You can prepare the squash casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours before baking. I often do this to save time on busy days. Just add a few more minutes to the baking time if it’s coming out cold from the fridge.

Q2: What’s the best way to prevent watery squash casserole?
You’re not alone in this—soggy casserole is a common struggle! The key is draining your summer squash well. After slicing, sprinkle with salt and let it sit for at least 20 minutes. Then press or squeeze out the moisture before mixing. Also, sautéing the squash briefly can help reduce excess water.

Q3: Can I make this casserole dairy-free?
For sure! You can swap sour cream with a plant-based yogurt or coconut cream and choose vegan cheese alternatives. Just watch the seasoning and moisture levels—they might need adjustments to keep the casserole cozy and creamy.

Q4: What’s the difference between southern squash casserole and other versions?
Southern squash casserole often features a creamy base with cheddar cheese and a crispy breadcrumb topping, capturing that perfect blend of comfort and texture. Other vegetable casseroles might use different veggies, sauces, or toppings, but the southern style is distinct for its cheesy, comforting richness.

Q5: Can I add other vegetables to my squash casserole?
Oh yes! Bell peppers, mushrooms, or even some corn kernels add nice texture and flavor. Just be mindful to adjust moisture and cooking time accordingly. This makes a lovely vegetable casserole with your summer squash as the star.

Q6: How do I know when my squash casserole is done?
You want the top to be golden brown and crispy, and the edges bubbling up. Insert a knife or fork in the center; it should come out hot and the casserole should feel set, not watery.

Q7: Any favorite substitutions for breadcrumbs?
I’ve used crushed Ritz crackers or even crushed cornflakes for that extra crunch. Panko crumbs are another fantastic choice for a lighter crunch.
