  • One batch Ratatouille
  • One cup quinoa rinsed, cooked according to package instructions and drained well
  • 1 1/2 cups grated mozzarella cheese divided


  • Preheat the oven to 350 degrees.  Spray a 9 x 13" baking dish with cooking spray.
  • Combine the ratatouille with the desired amount of quinoa.  I suggest using 2-2 1/2 cups of quinoa if you'd like your casserole to be a bit "saucier".  Add the remaining quinoa if you'd your casserole less saucy.  Stir in 3/4 cup of the cheese and pour into the prepared baking dish.
  • Top with the remaining cheese and bake for about 30 minutes or until bubbly and golden brown.  Remove from heat and cool for about 10 minutes.
  • Serve and enjoy!


  • Cook time for the ratatouille is not included as you can choose whether to make it on the stove top or try my Instant Pot Ratatouille.
  • The ratatouille may be made in advance and even frozen until ready to use.  Simply thaw, toss with quinoa and cheese and bake!
  • The casserole may be assembled up to a day in advance.  Bring to room temperature for 30 minutes before baking as a cold casserole will take longer to bake.
