Ingredients
This recipe makes 6 servings, with each serving being low in WW SmartPoints.
Base Ingredients:
- Eggs: 6 large (or substitute with liquid egg whites for fewer points)
- Egg Whites: 1 cup (approximately 8 large egg whites)
- Low-Fat Milk: 1/2 cup (or unsweetened almond milk for fewer points)
- Turkey Sausage: 1/2 pound (99% lean, cooked and crumbled)
- Potatoes: 2 medium-sized (about 2 cups, shredded or diced)
- Onion: 1 medium, finely chopped
- Bell Peppers: 2 medium, chopped (use a mix of colors for added vibrancy)
- Spinach: 2 cups, chopped
Seasonings:
- Garlic Powder: 1 teaspoon
- Onion Powder: 1 teaspoon
- Paprika: 1/2 teaspoon
- Salt and Black Pepper: To taste
Toppings:
- Reduced-Fat Cheddar Cheese: 1/2 cup, shredded
- Green Onions: 2, sliced

Instructions
Step 1: Preheat the Oven
- Preheat your oven to 375°F (190°C).
- Lightly spray a 9×13-inch baking dish with nonstick cooking spray or line it with parchment paper.
Step 2: Prepare the Turkey Sausage
- In a nonstick skillet over medium heat, cook the turkey sausage until browned and fully cooked, about 5–7 minutes.
- Remove from the skillet, crumble it into smaller pieces if needed, and set aside.
Step 3: Sauté the Vegetables
- In the same skillet, add the onions and bell peppers. Cook for 3–4 minutes until softened.
- Add the spinach and cook for an additional 1–2 minutes until wilted. Remove from heat and set aside.
Step 4: Prepare the Potato Layer
- If using raw potatoes, shred or dice them finely. Parboil the shredded potatoes for 3–4 minutes or microwave them for 2 minutes to ensure they cook evenly in the casserole.
Step 5: Whisk the Egg Mixture
- In a large bowl, whisk together the eggs, egg whites, and milk until well combined.
- Stir in the garlic powder, onion powder, paprika, salt, and pepper.
Step 6: Assemble the Casserole
- Layer the prepared potatoes evenly at the bottom of the baking dish.
- Spread the cooked turkey sausage over the potatoes.
- Add the sautéed vegetables evenly across the dish.
- Pour the egg mixture over the top, ensuring it covers all the ingredients.
Step 7: Add the Cheese
- Sprinkle the reduced-fat cheddar cheese evenly over the casserole.
Step 8: Bake the Casserole
- Place the baking dish in the preheated oven and bake for 35–40 minutes or until the eggs are fully set and the top is golden brown.
- Test doneness by inserting a knife or toothpick in the center; it should come out clean.
Step 9: Rest and Garnish
- Remove the casserole from the oven and let it rest for 5–10 minutes.
- Garnish with sliced green onions before serving.
Step 10: Serve and Enjoy
- Cut into 6 equal portions and serve immediately. Pair with fresh fruit or a small side of whole-grain toast for a complete meal.
