  • 6 large yellow squash sliced in ¼ inch slices (about 2½ pounds squash)
  • 8 oz shredded cheddar cheese divided
  • 2 large eggs
  • ½ sweet onion diced
  • 7 Tbsp butter divided
  • 1 ½ cups almond flour
  • 1 tsp salt


  • Preheat oven to 350.
  • Bring a medium pot of salted water to a boil. Add the squash and cook 5 minutes or until just becoming tender. Drain well in a colander and let cool for a few minutes.
  • While the squash is cooling, melt 2 tablespoons of butter in a small saucepan over medium high heat. Add diced onions and cook until translucent. Remove from heat and let cool slightly.
  • In a medium sized bowl, combine almond flour, remaining butter (melted), 2 oz cheese and salt for crumble topping.
  • In a large mixing bowl, combine squash, onions (and the butter they cooked in!), 6 oz cheese, and eggs. Pour into a greased 9 x 13 inch casserole dish.
  • Add crumble topping to the top of the casserole, crumbling with your fingers.
  • Cook 30 minutes or until egg is set and edges and topping are beginning to brown.
