Key Ingredients & Substitutions
Turkey sausage: Ground turkey sausage provides lean protein and great flavor. You can substitute with chicken sausage or plant-based sausage for a different taste or dietary preference.
Cottage cheese: I recommend using full-fat cottage cheese for creaminess. If you’re looking for low-fat options, low-fat or non-fat versions work fine. Alternatively, ricotta cheese gives a similar texture.
Cheddar cheese: While I love sharp cheddar for its flavor, feel free to swap it for mozzarella, gouda, or pepper jack for a spicy kick.
Chives: Fresh chives brighten the dish! If you don’t have any, green onions work well as a substitute. Dried chives can be used too, though the flavor is milder.
Red bell pepper: Not a fan of bell peppers? You can use diced zucchini or spinach for added veggies without the extra crunch.
How Do I Ensure My Casserole Comes Out Perfectly Set?
Getting your casserole perfectly set is key for a great texture. It should be firm but not dry. Here’s how to achieve that:
- Check cooking time: Depending on your oven, it may take a bit longer or shorter. Look for the edges to be golden and the center to be firm.
- Test with a knife: Insert a knife in the center; if it comes out clean, the casserole is ready.
- Let it rest: Allowing the casserole to cool for 5-10 minutes helps it firm up, making it easier to slice.
Following these tips will help you create a delicious and visually appealing breakfast casserole. Happy cooking!

Cottage Cheese Turkey Sausage Breakfast Casserole
Ingredients You’ll Need:
- 1 lb ground turkey sausage
- 3 cups cottage cheese (preferably full fat)
- 8 large eggs
- 1 cup shredded cheddar cheese
- 1/4 cup chopped fresh chives or green onions, plus extra for garnish
- 1/2 cup diced red bell pepper
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 tsp garlic powder
- Cooking spray or butter (for greasing casserole dish)
How Much Time Will You Need?
This delicious casserole will take about 15 minutes to prepare and about 35-40 minutes to bake. So, in total, set aside around 50-55 minutes from start to finish. It’s a perfect option for any busy morning or a leisurely brunch with family!
Step-by-Step Instructions:
1. Preheat the Oven:
Begin by preheating your oven to 350°F (175°C). While the oven warms up, lightly grease a 9×9 inch (or similar sized) casserole dish with cooking spray or butter to prevent sticking.
2. Cook the Turkey Sausage:
In a skillet set over medium heat, add the ground turkey sausage. Cook it until it’s nicely browned and cooked through, which should take about 5-7 minutes. Make sure to break it apart into crumbles as it cooks. Once done, drain any excess fat and let it cool slightly while you prepare the other ingredients.
3. Mix the Egg Ingredients:
In a large mixing bowl, whisk together the eggs, cottage cheese, salt, black pepper, and garlic powder. Mix them until everything is smooth and well combined. It will be a bit thick, and that’s perfectly fine!
4. Combine the Sausage and Veggies:
Next, stir the cooked turkey sausage, diced red bell pepper, chopped chives (or green onions), and 3/4 cup of the shredded cheddar cheese into the egg mixture. Mix everything together until evenly distributed.
5. Pour and Spread:
Now, pour the entire mixture into the greased casserole dish. Use a spatula to spread it out evenly so it cooks uniformly.
6. Add the Final Touch:
Sprinkle the remaining 1/4 cup of cheddar cheese on top of the mixture. This will create a delicious cheesy layer as it bakes.
7. Bake Your Casserole:
Place the casserole in the preheated oven and bake uncovered for 35-40 minutes. Keep an eye on it! You’ll know it’s ready when the center is set and the top is golden brown.
8. Let It Cool:
Once out of the oven, let the casserole cool for about 5-10 minutes. This will make slicing easier and ensure it holds its shape.
9. Serve and Garnish:
Slice the casserole and serve warm. Top it with any extra chopped chives or green onions for a fresh touch. Enjoy your hearty breakfast casserole!
This casserole is rich, cheesy, and packed with protein from the cottage cheese and turkey sausage—perfect for a hearty breakfast or brunch. Enjoy!
Can I Use a Different Kind of Meat Instead of Turkey Sausage?
Absolutely! You can substitute ground turkey sausage with chicken sausage, pork sausage, or even a plant-based sausage for a vegetarian option. Just ensure that any meat you choose is fully cooked before adding to the casserole.
Can I Make This Casserole Ahead of Time?
Yes, you can prepare the casserole the night before! Just assemble it without baking, cover it tightly, and refrigerate. In the morning, pop it in the oven right from the fridge, adding a few extra minutes to the baking time if needed.
What’s the Best Way to Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or in the oven until warmed through. You can also freeze portions for up to 2 months—just thaw in the fridge overnight before reheating.
Can I Add More Vegetables to This Recipe?
Definitely! This casserole is very adaptable. Feel free to add sautéed spinach, mushrooms, or zucchini for extra veggies. Just be sure to chop them small and consider cooking them briefly to release any moisture before adding to the mixture.
