There is something quite Southern about yellow squash. It is being grown in abundance on local farms. The beautiful yellow blooms are pretty enough to make a bouquet, but those beauties are needed to pollinate the squash and make it grow into this deliciousness.

During this time, I find many ways to get this veggie on my menu! I will be sharing some of those dishes with you soon.

This classic is a southern staple it seems. I don’t know many of my southern foodie friends that haven’t made this delightful dish! After all, it is smothered in butter, cheese, and Ritz crackers! I mean can it get much better than this?


  • Yellow Squash
  • Onion
  • Butter
  • Salt and Pepper to taste
  • Egg
  • Cheddar Cheese
  • Sour Cream
  • Ritz Crackers


Now turn on the ole faithful oven and get it heating up to 350 degrees. And BUTTA up that dish!

Yellow Squash frying in a cast iron skillet with salt and pepper on top

On the stove top heat a skillet (my preference is a cast iron skillet) over medium high heat. Melt that glorious BUTTA!! Add in the sliced squash and salt and pepper it to taste! Then saute and stir it lots for about 10 minutes or until it’s nice and soft. Drain it in a colander.  Let it sit a few minutes to get that water off!

Cooked Yellow Squash mixed with sour cream, egg and cheese

In a good sized, bowl mix together 1 cup of cheese, sour cream, and egg. Then fold in the cooked yellow squash!

Pour mixture into the prepared baking dish. Top with cheese and crushed cracker then drizzle butter on top. Bake uncovered for 20 to 30 minutes, until nice and golden brown and oh so bubbly!

Remove from oven and serve while warm and delicious!

Helpful Tools

  • Good Knives are a must in the kitchen for any home cook. I have fallen in love with Kyocera ceramic knives. I have the 5 inch, 7 inch , and a pairing knife!
  • A Cutting Board is also essential! I use a nice large wood board almost every day and also keep a utility board on hand too! As long as they are nice and sturdy they will make cutting an easy task in the kitchen.
  • A Large Skillet is my go to tool for my kitchen. My favorite is cast iron, but I always have a nonstick skillet too. I like something with a heavy bottom and high sides.
  • A classic Baking Dish is a must have. They don’t have to be fancy. I find I use my standard glass pyrex a lot. They often have lids and are easy to store leftovers or take to a potluck.  I also like stoneware baking dishes. They cook wonderfully and keep your food warmer for a longer period of time.

  1. your directions say ‘egg” but I didn’t see one listed on any of the ingredients. But I am tired. so maybe it’s there. looks delish though, so can’t wait to make it. Is it 1 egg or 2?
