High-Protein Turkey Sausage Breakfast Bake
This high-protein turkey sausage breakfast bake leans on sharp cheddar and whole wheat bread for a dense, savory morning slice. It takes fifteen minutes to assemble before the oven does the heavy lifting, making it exactly what a lazy Saturday needs.


Assembling the Layers
Start by spreading your cubed whole wheat bread and cooked turkey sausage across the bottom of a greased baking dish. Whisk your liquid eggs, nonfat milk, green onions, and spices in a large bowl. You might catch a harsh whiff of the dry mustard powder here. Don’t worry—it mellows completely in the oven into a warm, savory depth.
Pour the liquid mixture slowly over the bread. Watch for this—the first time I made it, I dumped the liquid in all at once. The bread cubes just floated to the top, leaving the bottom bare. Pour gently, then press the bread down lightly with a spatula. This helps it absorb the eggs instead of swimming in them.
Top with the cheddar, cover tightly with foil, and bake at 350°F for 20 minutes. Remove the foil and let it finish until the center is barely set and the edges brown.


A Few Morning Adjustments
- The bread matters: Using a hearty loaf gives the best texture. I often use leftovers from my whole wheat bread bakes for this.
- Drink pairings: A bright, acidic drink cuts the richness of the cheese nicely. I usually blend a quick Mediterranean smoothie while the casserole cools on the counter.
Storage & Reheating
- To Store: Keep leftover squares in an airtight container in the fridge for up to four days.
- To Reheat: A microwave works fine, but tossing a slice in the air fryer for three minutes brings back the crispy edges.
Quick FAQs
Can I assemble this the night before?
Yes. Cover the unbaked dish and leave it in the fridge overnight. Add five to ten minutes to your final uncovered bake time.
Can I use a different type of sausage?
Absolutely. Chicken or pork sausage works just as well, as long as it is fully cooked and diced before going into the dish.

Description
This wholesome, American-style breakfast casserole offers a lighter take on the classic strata, combining savory turkey sausage with whole grains for a satisfying start to the day. It is designed to provide a source of protein and flavor without the heaviness of traditional brunch dishes.
Ingredients
- 4 slices whole wheat bread (cut into 1/2-inch cubes)
- 4 precooked turkey breakfast sausage patties (diced)
- 1/2 cup reduced-fat sharp cheddar cheese (shredded)
- 16 oz liquid egg substitute (approx. 2 cups)
- 2 cups nonfat milk
- 1/2 cup green onions (chopped)
- 1/2 tsp dry mustard powder
- 1/4 tsp garlic powder
- 1/4 tsp black pepper
- 1/8 tsp salt (optional)
- Nonstick cooking spray
Instructions
- Preheat oven to 350°F (175°C). Generously coat a 9×13-inch baking dish with nonstick cooking spray.
- Arrange the whole wheat bread cubes and diced turkey sausage evenly across the bottom of the prepared baking dish.
- In a large mixing bowl, whisk together the liquid egg substitute, nonfat milk, chopped green onions, dry mustard powder, garlic powder, black pepper, and optional salt until well blended.
- Slowly pour the egg mixture over the bread and sausage, ensuring the liquid is distributed evenly to soak the bread. Top evenly with the shredded cheddar cheese.
- Cover the dish tightly with aluminum foil and bake for 20 minutes.
- Remove the foil and bake for an additional 35-40 minutes, or until the center is set and the top is lightly golden.
- Remove from the oven and allow the casserole to rest for 15-20 minutes on a wire rack before slicing.
Notes
- Doneness Tip: To ensure the eggs are fully cooked without becoming rubbery, insert a knife near the center; it should come out clean when the dish is done.
- Allergy Alert: This recipe contains Wheat (Gluten), Eggs, and Milk (Dairy). Use gluten-free bread or dairy-free cheese/milk alternatives if necessary.
