This side dish recipe is a quick and delicious way to cook yellow squash – with lots of butter. It is inspired by a recipe from a New Orleans restaurant called Tujague’s and it is so delicious.

Onions and red bell peppers are cooked in lots of butter, then round slices of summer squash are added. They simmer in the butter and sop it up – along with some chicken broth – and it becomes flavorful and delicious. 

You can also add a little bacon grease like you do when making Southern green beans or collard greens, but I love the simplicity of the flavor of butter.

Variations

  • I love to make this recipe using yellow summer squash, but you can also use zucchini rounds, diced patty pan squash, or really any other squash from the garden.
  • Use bacon grease instead of butter.
  • Make it vegetarian by using vegetable broth.

Storage & Reheating

Store leftovers in the fridge.

Reheat in the microwave until the butter melts. If there’s extra butter, you can use it to fry eggs with a little cheese – yum!
