Ingredients
  

  • 4 tablespoons butter divided
  • 1 large zucchini or 2 medium zucchinis chopped into 1/2 inch cubes
  • 1 small onion diced
  • 1/4 cup flour
  • 3/4 cup chicken broth
  • 1/2 cup half and half or milk
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 1/2 cup shredded cheddar cheese divided
  • 1 cup about 2/3 sleeve of buttery crackers, such as Ritz Crackers
  • 1 egg beaten

Equipment

  • 8x8 inch casserole dish
  • Large mixing bowl
  • Cutting board
  • Knife
  • Cheese grater, if grating a block of cheese yourself, which I do recommend
  • Measuring cups and spoons
  • Aluminum foil and plastic wrap, if freezing

Method
 

  1. Preheat your oven to 350°F.
  2. Melt 2 tablespoons of butter in a large skillet over medium-high heat.
  3. Add the zucchini and onion and cook for about 7 minutes, stirring occasionally, until the zucchini is tender and the onions are translucent. Transfer the mixture to a large bowl.
  4. In the same skillet used to cook the zucchini and onion, melt the remaining 2 tablespoons of butter over medium heat.
  5. Whisk the flour into the melted butter and cook for about 1 minute. (It will look like lumpy paste. That's okay! Trust the process.)
  6. Whisk in the broth and half and half until no lumps remain. After a minute or two, it will turn to a thick gravy consistency.
  7. Sprinkle in the garlic powder, salt, and pepper, and stir to combine.
  8. Pour the sauce into the bowl of zucchini and onion.
  9. Add 1 cup of the shredded cheese, the egg, and cracker crumbs. Stir gently until well combined.
  10. Pour the mixture into a greased 8X8 inch casserole dish.
  11. Sprinkle the remaining 1/2 cup of shredded cheese evenly over the top.
  12. Bake for 35-40 minutes, until golden and bubbly.
  13. Let it cool for a few minutes before serving.
