Ingredients

  • 3 medium potatoes cut into small cubes (about 3 cups)
  • 1 tbsp avocado oil
  • 1/2 tsp sea salt divided
  • 1/2 tsp black pepper divided
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 8 large eggs whisked
  • 1/3 cup milk of your choice (I used almond milk)
  • 3 slices turkey deli meat chopped
  • 1/2 cup cherry tomatoes diced (remove excess seeds if very juicy)
  • 2 tbsp green onions chopped
  • 1/2 tsp smoked paprika
  • pinch of red pepper flakes (optional)
  • oil or spray for greasing the pie dish

Instructions

  • Preheat oven to 400°F. If using an air fryer for the potatoes, preheat air fryer to 400°F.
  • In a medium bowl, toss the diced potatoes with avocado oil, garlic powder, onion powder, and half of the salt and pepper.
    3 medium potatoes, 1 tbsp avocado oil, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1/2 tsp sea salt

Air fryer method for potatoes (what I recommend):

  • Cook at 400°F for 15-20 minutes, shaking halfway through, until tender and slightly crispy. Preheat oven to 375°F while the potatoes finish.

Oven method for potatoes:

  • Spread onto a sheet pan and roast for 22 to 28 minutes, flipping halfway through, until fork tender and lightly golden.
  • Reduce the oven temperature to 375°F once the potatoes are done.
  • Lightly grease a 9-inch pie dish.
  • In the same bowl used for the potatoes, add the roasted potatoes, chopped turkey deli meat, diced tomatoes, green onions, whisked eggs, milk of your choice, smoked paprika, remaining salt and pepper, and red pepper flakes if using. Stir everything together until evenly combined.
    8 large eggs, 1/3 cup milk of your choice, 3 slices turkey deli meat, 1/2 cup cherry tomatoes, 2 tbsp green onions, 1/2 tsp smoked paprika, pinch of red pepper flakes
  • Pour the mixture into the prepared pie dish and spread it into an even layer.
  • Bake at 375°F for 30 to 38 minutes, or until the center is set and a knife inserted comes out clean.
  • Let rest for 10 minutes before slicing and serving.

Notes

  • Dice potatoes small for even cooking and best texture.
  • Let potatoes cool slightly before mixing to avoid scrambling the eggs.
  • Remove excess moisture from tomatoes to prevent a watery casserole.
  • Don’t overbake or the eggs can become rubbery.
  • The center should be just set when you remove it from the oven.
  • You can customize with extra veggies like spinach, peppers, or mushrooms.
