Ingredients

  • 16 ounces broccoli (see notes)
  • 1 onion or leek, diced
  • 12 tablespoons olive oil
  • 1 red bell pepper, diced
  • 8 ounces mushrooms, sliced
  • pinch salt and pepper
  • ——–
  • 12 large eggs
  • 1 cup ricotta (or sour cream)
  • 1 cup heavy cream (or sour cream)
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • ———
  • 1/2 cup fresh basil (save some for garnish)
  • 12 cups chopped baby spinach
  • 12 cups grated mozzarella (or other melty cheese- cheddar, jack, or crumbled goat cheese)

Instructions

Preheat oven to 350F

Make the veggie filling: Cut the broccoli into small florets and steam until just tender, let cool. At the same time, saute the onion or leek in olive oil, 3-4 minutes, over medium heat. Add the peppers and mushrooms and season with salt and pepper. Keep sauteing until tender.

Make the custard: While the veggies are cooking whisk (or blend in a blender) the eggs with the ricotta, cream, salt and pepper. ( Most any combo of ricotta, sour cream and cream will work here- 2 cups total.)

Assemble the frittata: Grease a deep 9 x 13-inch baking dish or 12-inch skillet. Pour 1/2 of the egg mixture in the bottom. Add the cooked veggies (you should have roughly 6 cups). Add the basil, spinach and cheese and pour in the remaining egg mixture. Give the veggies and little swirl so egg mixture is incorporated.

Bake: in the middle of the oven until the center is puffed and the frittata is nice and golden about 1 hour. Check at 30-40 minutes and tent with foil if getting too dark.

You’ll know frittata is done with it puffs slightly at the very center and is not too wobbly.

Let stand 5 minutes before serving.

Leftovers keep 4 days in the fridge.


Notes

Veggies: Feel free to swap other veggies for these- just make sure they are cooked and lightly seasoned with salt and pepper. Think roasted potatoes or sweet potatoes, roasted butternut squash, roasted cauliflower, sauteed zucchini, frozen spinach or corn, roasted peppers, sundried tomatoes, chili peppers, wilted kale or chard.  In summer I’ll top it with fresh vine-ripened cherry tomatoes. In spring, I’ll add raw asparagus tips. You’ll need 6 cups of cooked veggies total. 

Cast-Iron: If you would like to bake this in a cast-iron skillet- no problem, make sure it is extra-large (12 inches in diameter) and greased well.

If making ahead: assemble, refrigerate, and make sure to bring unbaked refrigerated frittata to room temp one full hour before baking. Frittata can also be baked ahead and reheats well.

When Halving the recipe-bake in a standard 9-inch pie pan, or 9-inch cast-iron skillet.
