Why You’ll Love This Recipe
High Protein, Lower Fat
Traditional versions rely on sour cream and condensed soup. We replace these with non-fat Greek yogurt and cottage cheese blended together. This “secret sauce” creates a creamy, cheesy texture that mimics the original but adds a massive punch of protein and probiotics while slashing the fat content.
Veggie-Packed Volume
This dish is a prime example of volume eating. By bulking up the casserole with fresh spinach, onions, and peppers, you get a larger, more filling portion for fewer calories. It’s an effortless way to get 2-3 servings of vegetables in before noon.

- 1 cup plain non-fat Greek yogurt
- 1 cup cheddar cheese, shredded (reduced fat optional)
- 1 tsp garlic powder
- 1/2 tsp salt
Instructions

- Sauté turkey sausage, peppers, and spinach in a skillet until cooked.

Ingredient Highlights & Substitutions
Essential Ingredients
- Frozen Hashbrowns: Look for brands with no added oil or salt. Thaw them and squeeze out the water to ensure the casserole isn’t soggy.
- Lean Turkey Sausage: Provides savory breakfast flavor with a fraction of the saturated fat of pork sausage.
- Egg Whites + Whole Eggs: We use a mix. The whole eggs provide richness and vitamins, while the whites boost the protein structure.
- Greek Yogurt: Plain, non-fat Greek yogurt adds tang and creaminess.
- Fresh Spinach: Chopped fresh spinach wilts beautifully into the bake.
- Bell Peppers: Red and yellow peppers add sweetness and Vitamin C.
Smart Substitutions
- Vegetarian: Skip the sausage and add sautéed mushrooms or black beans for a plant-based protein boost.
- Dairy-Free: Use a high-quality almond milk yogurt and nutritional yeast or vegan cheese shreds.
- Potato Swap: For an even lower-carb option, swap half the hashbrowns for riced cauliflower. You won’t even taste the difference once it’s baked with the spices.
Step-by-Step Instructions
Prep Phase
Preheat oven to 375°F (190°C). Grease a 9×13 baking dish with olive oil spray. Squeeze your thawed hashbrowns dry in a clean kitchen towel.
Cooking Phase
- Sauté Aromatics: Heat a skillet over medium heat. Cook the turkey sausage until browned, breaking it apart. Add the diced onion and peppers and cook for 3 minutes until soft. Stir in the spinach until wilted.
- Prepare the Base: In a large bowl, whisk together the eggs, egg whites, Greek yogurt, garlic powder, salt, and pepper until smooth.
- Combine: Stir the hashbrowns, cooked sausage-veggie mixture, and half of the cheese into the egg bowl. Mix well.
- Bake: Pour the mixture into the prepared baking dish. Top with the remaining cheese.
- Cook: Bake for 40-50 minutes. The center should be set (not jiggly) and the edges golden brown. Let cool for 10 minutes to set before slicing.
Pro Tips for Perfect Results
Technique Secrets
The Cottage Cheese Hack. If you want extra creaminess, blend 1/2 cup of cottage cheese into your eggs. It melts down and creates cheesy pockets without needing as much actual cheddar.
Common Mistakes to Avoid
- Soggy Veggies: Vegetables release water. Sautéing them before adding them to the casserole ensures the excess moisture evaporates in the pan, not in your casserole.
- Over-browning: Since this is a lighter casserole, it can dry out. If the top gets brown before the center sets, cover loosely with foil.
Serving Ideas & Pairings
Presentation & Plating
Serve squares on white plates with a side of sliced avocado and fresh berries. The green avocado adds healthy fats that make the meal even more satiating.
Pairing Suggestions
This savory dish pairs beautifully with a light, citrusy sweet.
If you are looking for a guilt-free dessert to round out your brunch, these Lemon Bars are a bright and zest option that complements the veggies perfectly.
