Baked until the top is golden and bubbly, it's ready to serve alongside your favorite entrees.
Easy Homestyle Squash Casserole Recipe
Squash casserole is another dish that was regularly seen on our table when we were kids. My Dad typically grew yellow squash and zucchini. It's the kind of garden comfort food that I learned to make as a girl, from my Mom and I continue to love it to this day. I've also noted that making squash this way seems to be one of those sumptuous squash side dishes that kids will like better than steamed vegetables. That's always a huge perk for me being a Mom of two hungry teenage boys.
How to Make the Best Homestyle Squash Casserole Recipe
- Ingredients you'll need to make Homestyle Squash Casserole: Yellow squash, diced onion, salt, mayonnaise, sour cream, black pepper, granulated garlic, Italian seasoning, large eggs, Parmesan cheese, shredded sharp cheddar cheese, dry cornbread stuffing mix, (i.e. Pepperidge Farm or similar) and melted butter.
- Kitchen gadgets you'll need: A large bowl, cheese grater, sharp knife and cutting board, a 4 quart pot or saucepan, a large spoon or spatula for stirring, measuring cups and spoons and a 13 x 9 inch baking dish.
- Can You Use Crackers for the Topping? A resounding, yes! This squash dish can be topped with dry herb stuffing as I call for in the recipe, or crushed crackers such as Ritz or Club crackers.
- The casserole filling can be assembled one day in advance then covered and chilled. I recommend that you wait and add the topping just before baking.
- Store leftover Homestyle Squash Casserole chilled in the refrigerator for up to 3 days. Reheat in a 350°F oven for 15 minutes or until heated through or in single serving portions in the microwave.
Put Yellow Squash on the Manu Year-Round
While we most often think of yellow squash using the warm summer months, we're so blessed to have suppliers that make it possible to enjoy year-round. This casserole would be perfect for fall meals and Thanksgiving, too. It's a dish you'll find on our table anytime of year, it's a taste of the South in your mouth.

So YUMMY!!! Will definitely make this again. Used Stove Top Stuffing mix for the top with the 4 tbsps of butter. Worked beautifully!
I'm so happy you enjoyed it!
Just like my Mom used to make, we just love this casserole. I make it for Thanksgiving too, not just in the summer.
I have made this recipe several times and my family will requests it every time they see squash or zucchini! It is so delicious 😋!
I love that you also use zucchini, you're absolutely right it's interchangeable. I'm so happy your family enjoys this, thank you!

This was awesome! I didn't have the herb stuffing mix, so I used Ritz crackers. So flavorful and an excellent way to use a bumper summer squash crop! Thank you!
Ritz crackers are the perfect substitution, thanks so much!
Could you use Zucchini in place of the yellow squash, or mix them?
Absolutely, either way works.
Hi, do you have to peel the squash too or just slice like coins
Hi Jennifer, I don't ever peel the squash for this recipe. Slice into rounds, yes, just not too thin.
Sounds delicious! Similar to one my sister makes and our family loves!
I love squash casserole and could make a meal of it alone. Thank you!
Thank you so much for the squash casserole recipe of "old" like our parents use to make with the Pepperidge Farm dressing. I have looked everywhere for this and just found it on your website. Thank you AGAIN.
That's precisely why I love it, this is how I was introduced to squash casserole, too. Thanks for stopping by for a visit!
Thank you Melissa!

I didn't know what to expect from the title. You know I do not think I have encountered a squash casserole anywhere near this one. What a winner! No wonder it was a family favorite comfort food. I am going to introduce it to my family.
