Ingredients:

1 pound lean ground turkey sausage (or your preferred lean breakfast sausage)
1 tablespoon olive oil (or your preferred cooking oil)
1 large yellow onion, finely chopped
1 large red bell pepper, finely chopped
1 cup fresh spinach, roughly chopped
12 large eggs
1 cup low-fat cottage cheese
½ cup milk (dairy or non-dairy, unsweetened)
¼ cup all-purpose flour (or a gluten-free alternative like oat flour)
1 teaspoon baking powder
½ teaspoon salt
¼ teaspoon black pepper
¼ teaspoon garlic powder
¼ teaspoon onion powder

Cooking spray or butter for greasing the baking dish

Prepping Your Delicious High Protein Cottage Cheese Turkey Sausage Breakfast Casserole Ingredients

Preheat Your Oven and Prepare Your Baking Dish: Before we dive into the fun stuff, let’s get our oven ready. Preheat your oven to 375°F (190°C). While it’s heating up, grab a 9×13 inch baking dish. This size is perfect for ensuring an even bake for our generous High Protein Cottage Cheese Turkey Sausage Breakfast Casserole. Liberally spray the inside of the dish with cooking spray, or grease it thoroughly with butter. This crucial step prevents your casserole from sticking, making cleanup a breeze and ensuring every glorious piece comes out intact.
Cook the Turkey Sausage: Place a large skillet over medium-high heat. Add your tablespoon of olive oil. Once shimmering, add the pound of lean ground turkey sausage to the pan. Using a wooden spoon or spatula, break up the sausage into small, crumble-like pieces as it cooks. Stir frequently to ensure even browning. You’re looking for the sausage to be fully cooked through and no longer pink, which typically takes about 5-7 minutes. Once cooked, transfer the sausage to a plate lined with paper towels to drain any excess grease. This helps keep our casserole from becoming oily and maintains that lean, high-protein profile.
Sauté the Aromatics and Vegetables: Using the same skillet (you can drain off any remaining residual grease if there is any, but typically with lean turkey sausage there isn’t much), reduce the heat to medium. Add the finely chopped yellow onion and red bell pepper. Sauté these vegetables for about 5-7 minutes, stirring occasionally, until they soften and become fragrant. We want them tender but not mushy, as they’ll continue to cook in the oven. The softening process here releases their natural sweetness and deepens their flavor, which is key for a well-rounded breakfast casserole.
Wilting the Spinach: Once the onion and bell pepper are tender, add the roughly chopped fresh spinach to the skillet. Continue to cook for another 1-2 minutes, stirring constantly, until the spinach wilts down significantly. It will shrink quite a bit, so don’t be alarmed if it looks like a lot at first! This step ensures the spinach is incorporated smoothly into the casserole without releasing too much water during baking.
Prepare the Egg and Cottage Cheese Mixture: In a very large mixing bowl, crack all 12 large eggs. To these, add the entire cup of low-fat cottage cheese. This is where a significant portion of the “High Protein” aspect of our High Protein Cottage Cheese Turkey Sausage Breakfast Casserole comes from, providing a wonderful creamy texture and protein boost. Pour in the ½ cup of milk.
Whisk in Dry Ingredients and Seasonings: Now, add the ¼ cup of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of salt, ¼ teaspoon of black pepper, ¼ teaspoon of garlic powder, and ¼ teaspoon of onion powder to the egg mixture. If you enjoy a little heat, go ahead and add that pinch of red pepper flakes now. Vigorously whisk everything together until the mixture is smooth and well combined. Make sure there are no lumps of flour and the cottage cheese is mostly broken down. The flour and baking powder here are important; the flour helps stabilize the egg mixture, preventing it from weeping during baking, and the baking powder contributes to a lighter, fluffier texture, making each bite of your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole wonderfully airy.

Assembling Your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole

Combine Sausage and Vegetables: To the large bowl containing the egg and cottage cheese mixture, add the cooked and drained turkey sausage. Then, add the sautéed onion, red bell pepper, and wilted spinach. Give everything a good stir with a large spoon or spatula to ensure all the components are evenly distributed throughout the mixture. This even distribution is crucial for getting a balanced flavor and texture in every single serving of your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole.
Add the First Layer of Cheese: Stir in 1 cup of the shredded reduced-fat cheddar cheese into the mixture. Yes, directly into the wet ingredients! This helps to incorporate the cheesy goodness throughout the casserole, rather than just having it on top. It contributes to the overall savory depth and creates pockets of melted cheese throughout the baked dish.
Transfer to the Baking Dish: Carefully pour the entire casserole mixture into your prepared 9×13 inch baking dish. Use your spatula to spread it out evenly so that the ingredients are distributed from corner to corner.
Top with Remaining Cheese: Sprinkle the remaining ½ cup of shredded cheddar cheese over the top of the casserole mixture. This top layer of cheese will melt into a beautiful golden-brown crust as it bakes, adding a delightful texture and extra layer of flavor to your magnificent High Protein Cottage Cheese Turkey Sausage Breakfast Casserole.

Baking Your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole to Perfection

Initial Bake (Covered): Cover the baking dish tightly with aluminum foil. This step is important because it helps the casserole cook through evenly without the top browning too quickly. Place the covered dish into your preheated 375°F (190°C) oven and bake for 30 minutes. Baking covered creates a steamy environment, ensuring the egg mixture sets properly and the vegetables become perfectly tender, contributing to a moist and flavorful result.
Final Bake (Uncovered): After 30 minutes, carefully remove the foil. Return the uncovered casserole to the oven and continue baking for another 20-30 minutes, or until the casserole is set in the center and the cheese on top is beautifully melted, bubbly, and golden brown. To check for doneness, gently shake the dish; if the center has only a slight jiggle, it’s ready. You can also insert a knife into the center; if it comes out clean, your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole is perfectly cooked. Be mindful not to overbake, as this can lead to a dry casserole. Every oven is a little different, so keep an eye on it during this final stage!

Resting, Serving, and Enjoying Your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole

Let It Rest: Once baked to perfection, remove the casserole from the oven. This part requires a little patience, but it’s essential! Let the High Protein Cottage Cheese Turkey Sausage Breakfast Casserole rest for 10-15 minutes before slicing and serving. This resting period allows the egg mixture to fully set and firm up, making for cleaner cuts and preventing the casserole from falling apart when you scoop it out. It also allows the internal temperatures to equalize, ensuring every bite is uniformly delicious.
Garnish and Serve: If desired, sprinkle with fresh chopped chives or parsley just before serving. These fresh herbs add a lovely pop of color and a touch of fresh flavor that brightens up the rich casserole. Slice the casserole into generous squares and serve warm. This dish is fantastic on its own, but it also pairs wonderfully with a side of fresh fruit, a simple green salad, or a dollop of your favorite salsa or hot sauce for an extra kick. Each serving offers a fantastic balance of protein, vegetables, and complex flavors, making it an ideal choice for a satisfying and nutritious start to your day.

Make-Ahead Tips and Storage for Your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole

One of the best things about this High Protein Cottage Cheese Turkey Sausage Breakfast Casserole is how incredibly versatile it is for meal prep! You can assemble the entire casserole the night before. Simply follow all the steps up to adding the remaining cheese on top (Step 10). Then, cover the dish tightly with plastic wrap and refrigerate overnight. When you’re ready to bake it in the morning, remove it from the refrigerator about 30 minutes before baking to allow it to come closer to room temperature. You might need to add an extra 5-10 minutes to the covered baking time, as it will be starting colder. This makes busy mornings so much easier, allowing you to wake up to the delicious aroma of a freshly baked, high-protein breakfast with minimal effort.

Leftovers: Any leftover slices of your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. They reheat beautifully in the microwave or in a toaster oven for a crispier edge. This makes it an excellent option for grab-and-go breakfasts or quick lunches throughout the week, ensuring you always have a protein-packed meal at your fingertips.

Freezing Instructions: If you’re looking to extend the life of your casserole even further, it freezes remarkably well! Once baked and completely cooled, you can slice the casserole into individual portions. Wrap each portion tightly in plastic wrap, then again in aluminum foil, or place them in freezer-safe containers. Frozen portions of the High Protein Cottage Cheese Turkey Sausage Breakfast Casserole will keep for up to 2-3 months. To reheat, simply unwrap a frozen portion and microwave it until heated through, or thaw it in the refrigerator overnight and then reheat in the oven or microwave. This makes batch cooking a breeze and ensures you always have a wholesome and convenient meal option on hand.

Customizing Your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole

This recipe is incredibly adaptable, allowing you to tailor it to your personal preferences or what you have on hand. Feel free to experiment with different vegetables! Diced zucchini, mushrooms, or even chopped kale would be fantastic additions. If you prefer a different kind of lean protein, ground chicken or even plant-based sausage crumbles can be used in place of the turkey sausage. For an extra cheesy kick, try adding a sprinkle of Parmesan cheese to the egg mixture, or experiment with different cheese blends for the topping, like Monterey Jack or Gruyere. The beauty of this High Protein Cottage Cheese Turkey Sausage Breakfast Casserole lies in its flexibility, so don’t hesitate to make it your own!

Want to get even more creative? Here are a few ideas to customize your High Protein Cottage Cheese Turkey Sausage Breakfast Casserole experience and make it uniquely yours:

Spice it Up: If you love a bit of heat to awaken your senses, consider adding a pinch of red pepper flakes to the egg mixture, or swap out some of the bell peppers for finely diced jalapeños (seeded or unseeded, depending on your preferred level of spiciness).
Veggie Power: Don’t be afraid to experiment with other vegetables from your crisper! Fresh spinach, sautéed mushrooms, diced zucchini, chopped asparagus, or even a handful of diced sweet potato can be fantastic additions. Just ensure any high-water content vegetables like zucchini are lightly sautéed first to remove excess moisture, preventing a soggy casserole.
Cheese, Please: While cottage cheese provides the essential protein and moist texture, a sprinkle of sharp cheddar, creamy Monterey Jack, or even a smoky gouda on top during the last 10 minutes of baking can add a delightful melted, golden-brown cheesy crust that’s utterly irresistible.
Herb Garden Freshness: Fresh herbs like fragrant dill, vibrant parsley, or aromatic basil can introduce entirely different flavor profiles. Mix them directly into the egg mixture for a subtle infusion or use them generously as a fresh garnish before serving.
Make it Meatless: For a delicious vegetarian version, simply omit the turkey sausage and compensate by adding extra vegetables, or consider incorporating a plant-based sausage alternative to maintain that savory depth.
Individual Portions: For ultimate meal prep convenience, divide the entire mixture into greased muffin tins and bake them as individual breakfast cups. Adjust baking time accordingly, likely around 20-25 minutes, until golden and set. These are absolutely perfect for grab-and-go mornings or portion-controlled snacks!
