How do you make Paula Deen's Squash Casserole
Well in full honesty, I too am a big fan of hers but no one can make as good as hers. My recipe is my own and somewhat similar but it tastes so good! So here's how to make my version of the famous Southern Squash Casserole recipe.
Cut the Squash and Onions into thin slices. Throw them in a big pot, add water and cover cook for 4-5 min over medium high heat.
After the Squash gets cooked, drain and set aside.
Combine Ritz Cracker Crumbs and Shredded Cheddar Cheese in a medium sized mixing bowl.
Whisk together Eggs, Whole Milk, Mayonnaise, Salt & Pepper in a mixing jar and set aside.
Arrange the cooked veggies in alternating motion in the baking dish.
Add some of the ritz cracker and cheese mixture after one layer and then top with the other layer.
Pour the milk and eggs mixture over it.
Top with rest of the cracker & cheese mixture. Place in the preheated oven and bake @400F for 20 min.
Once this gets cooked, get it out of the oven, let it rest for about 5-10 min and serve!
How do you keep Squash Casserole from getting watery?
The only and the best trick I always use is to cook the Squash in advance. You can either saute them in a skillet or even better cook them in a closed lid saucepan.
Cooking the Squash before baking them in the casserole, releases extra moisture from them.
Also don't forget the cracker crumbs topping over the Squash Casserole. It really makes a difference in taste and texture of this Yellow Squash Casserole.
Do you put eggs in Squash Casserole?
Yes, I put Eggs in my Yellow Squash Casserole because it really acts like a thickening agent in the casserole and doesn't get it get watery!
What can I do with a lot of Squash?
This is the most common problem we all face. Especially every July I get this huge chunk of Squash from the store and need recipes to make them.
I think the best way to use them is in the form of a casserole or a stir fry as it acts as a perfect bbq side dish.
Besides this here are some more Summer Squash recipes you might love.
Do you peel Yellow Squash before cooking?
NO. Yellow Squash has a very thin skin which gets cooked right upon boiling or sauteing. So you do not need to peel the skin of Yellow Squash before cooking.
Can I freeze leftover Squash Casserole?
Store leftover Summer Squash Casserole in an airtight container. Refrigerate this for up to 2 weeks. Reheat in the microwave and serve hot.
Freeze: Yes absolutely! Summer Squash Casserole is a perfect make ahead casserole. Bake it, cool it down to room temp. cover with plastic wrap and foil and freeze. You can freeze this for up to a month.
Reheat - Thaw overnight in the refrigerator and reheat before serving!
- Zucchini - instead yellow Squash you can use Zucchini as well. Or you can use both Zucchini and Yellow Squash like I did.
- Sour Cream Base - instead of Mayonnaise you can use thick and creamy Sour Cream. Its very commonly substituted with Mayonnaise. But I personally love the Mayo version!
- Pulsed Squash - many southerns dice the Squash and many slice it.Many even pulse it into a fine puree along with onions using a food processor. Then they add other ingredients and make the casserole.
- Gold Medal Flour - a perfect replacement for cracker crumbs in Gold Medal Flour, which is so commonly used. You can combine it with shredded cheddar cheese and top over the casserole.
- Cornmeal - I also sometimes add some Cornmeal to the Casserole. I usually add it in the milk mixture. I whisk it until combined and add to the Summer Squash Casserole. This acts like a thickening agent and also improves the taste a LOT!
- Spices & Herbs - a bit of Dried Thyme and some Cayenne Pepper acts as a perfect spice to this Summer Squash Casserole.

Top tips to make the Best Squash Casserole
- Use unsalted Butter - if you are using Butter to combine Ritz Crackers and Cheddar Cheese, then I would prefer to use Unsalted Butter
- Smaller Squash - I always prefer to use small and fat Squash as they are seedless and full of taste.
- Shred your own Cheese - I would prefer that you shred your own cheese.
- Mandolin Slicer - The best way to slice Squash is to use a Mandolin Slicer. You get thin slices which are perfect for this recipe.
