Ingredients
  

  • 8 large eggs
  • 1 cup heavy cream (you can use half heavy cream and half unsweetened almond milk for a lighter texture)
  • 1 1/2 cups shredded cheese (cheddar, Gruyère, or Swiss work well)
  • 6 slices bacon, cooked and crumbled (or 8 oz breakfast sausage, cooked and drained)
  • 1 cup spinach, roughly chopped (fresh or thawed and well-squeezed)
  • 1/2 cup mushrooms, sliced and sautéed
  • 1/4 cup onion, finely diced and sautéed (optional if you’re strict with carbs)
  • 2 tablespoons butter (for sautéing and greasing)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried thyme (or Italian seasoning)
  • 1/2 teaspoon kosher salt, plus more to taste
  • 1/4 teaspoon black pepper
  • Red pepper flakes to taste (optional)
  • Fresh chives or parsley, chopped, for garnish (optional)

Method
 

  1. Preheat and prep: Heat your oven to 350°F (175°C). Grease a 9-inch pie dish or a 9x9-inch baking dish with butter or spray.
  2. Cook the add-ins: In a skillet over medium heat, cook bacon until crisp, then crumble. If using sausage, cook and break into small pieces. Sauté mushrooms and onions in butter with a pinch of salt until softened and lightly browned. Add spinach and cook just until wilted. Let everything cool slightly.
  3. Whisk the egg mixture: In a large bowl, whisk eggs, heavy cream, garlic powder, thyme, salt, pepper, and red pepper flakes if using, until smooth and well combined.
  4. Layer the dish: Spread the cooked meats and veggies evenly over the bottom of the greased dish. Sprinkle most of the cheese over the top, reserving a small handful.
  5. Pour and top: Pour the egg mixture evenly over the fillings. Jiggle the dish gently to settle. Sprinkle the remaining cheese on top.
  6. Bake: Place on the center rack and bake for 28–35 minutes, or until the edges are set and the center has a slight jiggle. A knife inserted near the center should come out mostly clean.
  7. Rest and slice: Let it rest for 10 minutes before slicing. Garnish with chopped chives or parsley if you like.
  8. Serve: Enjoy warm as-is or with a simple side like sliced avocado or a small green salad.
