  • 8-10 small yellow squash sliced
  • 1 pound hamburger meat
  • 1 small onion diced
  • 1 10 ounce can cream of mushroom soup
  • 1 10 ounce can diced tomatoes with green chilies
  • 1 cup shredded cheddar cheese
  • 2 large eggs lightly beaten
  • 24 butter flavored crackers crushed


  • Bring a large stockpot of salted water to a boil. Add the squash, return the water to a boil and cook for 3 minutes. Immediately drain the squash and run under cold water to stop the cooking. Set aside to drain.
  • Brown the hamburger meat in a large skillet. Add the diced onion and cook until the hamburger is not longer pink and the onion is tender. Place the burger in a large mixing bowl.
  • Add the cream of mushroom soup, the diced tomatoes with green chilies, the shredded cheddar cheese and the two beaten eggs. Stir until everything is combined.
  • Add the squash to the bowl. Gently stir until the squash is evenly incorporated throughout the mixture.
  • Place the squash mixture in one large 9 x 12 x 2-inch casserole dish or two 8 x 8 x 2-inch casserole dishes. At this point, the squash can be covered with aluminum foil and stored in the fridge for up to 24 hours or frozen.
  • Preheat the oven to 350 degrees.
  • Sprinkle the crushed crackers over the top of the casserole.
  • Bake for 20-30 minutes until the casserole is bubbling and the cracker crust is golden brown. If using frozen squash, you may need to allow the casserole to bake for and extra 10-15 minutes. Allow casserole to rest for 10 minutes before serving.
