- Skillet
- Cutting board
- Knife
Ingredients
For the casserole
- 10 large eggs
- 1 cup heavy whipping cream
- 2 cups shredded sharp cheddar cheese divided, or use half cheddar and half mozzarella
- 1 cup shredded mozzarella cheese low-moisture, part-skim; for extra melt and stretch
- 2 cups diced sugar-free ham about 12 oz; choose ham with no added sugar
- 2 tablespoons butter for greasing the dish and sautéing vegetables
- 1/4 teaspoon garlic powder
- 1/4 teaspoon onion powder
- 1/2 teaspoon sea salt or to taste; ham and cheese are already salty
- 1/4 teaspoon black pepper freshly ground, or to taste
Optional low-carb vegetables
- 1 cup fresh spinach roughly chopped; about 1 large handful
- 1/2 cup red bell pepper diced small; about 1/2 medium pepper
- 2 tablespoons green onions sliced thin, for topping before or after baking
Instructions
- Preheat the oven to 350°F and generously grease a 9×13-inch baking dish with about 1 tablespoon of the butter.
- Place a skillet over medium heat and melt the remaining 1 tablespoon butter.
- Add the diced red bell pepper to the skillet and sauté for 3 to 4 minutes until it begins to soften, then add the chopped spinach and cook for another 1 to 2 minutes just until wilted and any excess moisture has cooked off.
- Remove the skillet from the heat and set the cooked vegetables aside to cool slightly while you prepare the egg mixture.
- In a large mixing bowl, whisk the eggs until well combined and slightly frothy.
- Whisk the heavy whipping cream, garlic powder, onion powder, sea salt, and black pepper into the eggs until the mixture is smooth and uniform.
- Stir in 1 and 1/2 cups of the shredded cheddar cheese, all of the mozzarella cheese, the diced sugar-free ham, and the sautéed vegetables until everything is evenly distributed in the egg mixture.
- Pour the egg and ham mixture into the prepared baking dish, spreading the ham and vegetables evenly so every bite has a bit of everything.
- Sprinkle the remaining 1/2 cup shredded cheddar cheese evenly over the top of the casserole, adding sliced green onions on top if you like them baked in.
- Bake the casserole for 30 to 35 minutes, or until the center is just set, the edges are puffed, and the top is golden and bubbly.
- Remove the baking dish from the oven and let the casserole rest for 5 to 10 minutes to firm up for clean slices and to allow the flavors to settle.
- Sprinkle with additional sliced green onions, if desired, then slice into 8 portions and serve warm, or let cool completely for meal prep and refrigerate or freeze for later.
