This Zucchini-Mushroom Frittata has a satisfying mix of dill seasoned veggies and a potent burst of the sweet onion topping. I’m pleased to report, it was recently voted the #1 favorite frittata by my family.


  • 1 large onion (cut in half and sliced 1/3 inch thick pieces )
  • 3 cups sliced zucchini (1/3 inch half rounds )
  • 8 -9 Shiitake mushrooms (sliced into bite size pieces or use 1/2 to 1 cup dried mushrooms)
  • 6 large eggs (cage free and organic are optimum)
  • 2 tablespoons water
  • 1/2 teaspoon dried dill (or substitute 1 T plus 1 t of finely chopped fresh dill)
  • 1/4 teaspoon salt
  • black pepper (to taste )
  • 2 tablespoons olive oil (this is approximately amount needed for sautes & oiling baking dish)


  • Step 1
  • White onions at time of turning heat to low

    Saute onion slices in olive oil (up to a tablespoon) on medium heat, stirring until lightly browned. I like the looks of some browned edges on the onions that comes with the use of medium heat. Turn the heat down to low stirring occasionally. Continue cooking until soft. Approximately 10 to 20 minutes. You can begin step 2 as the onions are on low, if you don’t mind multitasking.
  • Step 2
  • STep 2 in making zucchini for frittata by Luscious and Local

    In a separate pan, saute zucchini slices in a little olive oil. Add the dill and salt during this quick saute. (if you are using dried mushrooms soak them first in a small amount of warm water for a few minutes)
  • Step 3
  • Zuchinni, mushrooms, dill and salt in the saute pan

    Stir in the mushrooms. (if you are using dried mushrooms soak first in a small amount of warm water for a few minutes, before this step) Saute just until the zucchini is well heated and everything is mixed together. Turn the heat off and let rest while you prepare the eggs.
  • Step 4
  • A good size bowl makes whipping the eggs easier with less chance of mess

    Crack the eggs into a medium size mixing bowl. Add the water or 2 T of the liquid left over from soaking the mushrooms. Whip with a whisk until the eggs and water are very well mixed and frothy.
  • Step 5
  • Firttata is almost ready to place in the oven.

    Lightly oil a 9 X 9″ (or similar size) baking dish and evenly distribute the zucchini and mushroom mixture in the dish. Pour the frothy eggs over the vegetables. Top with the sauteed onions. Bake at 350 Degrees for about 30 minutes. Test the center with a knife. if the knife comes out clean it is done. It will be puffy when it is done and then settle as it begins to cool. Serve at once or serve at room temperature.
