Key Ingredients & Substitutions
Breakfast Sausage: This is essential for flavor. If you want a lighter option, turkey sausage works nicely. For a vegetarian twist, try using a meatless sausage or additional veggies like bell peppers and mushrooms.
Eggs: Large eggs are standard, but you can use egg whites or egg substitutes if you’re watching cholesterol. Just remember, adjust the amount based on substitution guidelines.
Cheddar Cheese: Cheddar gives a nice tang. Feel free to replace it with Monterey Jack or Colby for a different flavor. Vegan cheese can also work if you need a dairy-free option.
Cottage Cheese: This adds creaminess. If you’re not a fan, swap it out with ricotta or leave it out entirely for a simpler mix.
Green Onions: They add a fresh crunch. Chives or regular onions can substitute. Just chop them finely so they blend well.
How Can I Ensure Perfect Cooking in My Slow Cooker?
Cooking a breakfast casserole in a slow cooker is an easy way to have a hot meal ready when you wake up. However, to get it just right, pay attention to a few key points:
- **Layering:** Start with your wet ingredients, then add the meat and cheeses, finishing with the egg mixture on top to ensure even cooking.
- **Timing:** Cooking on low for 6-7 hours is ideal, especially if you’re making this overnight. On high, it takes 3-4 hours, but check at 3 hours so it doesn’t overcook.
- **Testing for Doneness:** Make sure eggs are set in the middle, not runny. If you poke it with a knife and it comes out clean, it’s ready!
- **Letting it Rest:** After cooking, let the casserole sit for about 10 minutes before cutting. This helps it firm up a bit.
With these tips, you’ll have a delicious breakfast casserole that everyone will love!

- 1/2 cup cottage cheese
Seasonings:
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
Extras:
- 4-5 slices cooked bacon, chopped (plus extra for garnish)

Detailed Instructions:
1. Cooking the Sausage:
Start by heating a skillet over medium heat. Add the breakfast sausage and cook it until it’s nicely browned and cooked all the way through, which should take about 5-7 minutes. Once done, drain any excess grease and set the sausage aside.
2. Mix the Egg Mixture:
In a large mixing bowl, crack the 10 large eggs. Add in the milk, salt, black pepper, garlic powder, and onion powder. Whisk everything together until well combined and frothy. This will give your casserole a nice, fluffy texture!
3. Combine the Ingredients:
Next, stir in the cooked sausage, shredded cheddar cheese, and cottage cheese into the egg mixture. Make sure everything is mixed thoroughly so that every bite has that yummy flavor.
4. Prepare the Slow Cooker:
Spray your slow cooker insert with nonstick cooking spray to prevent sticking. Pour the entire egg and sausage mixture into the slow cooker, spreading it out evenly.
5. Add the Bacon and Cheese:
Sprinkle the chopped cooked bacon over the top of the mixture, along with a little extra cheddar cheese for added flavor and a nice gooey texture once cooked.
6. Cook the Casserole:
Cover the slow cooker and set it to cook on low for 6-7 hours, or on high for 3-4 hours. You know it’s ready when the eggs are fully set and cooked through—no more runny eggs!
7. Garnish and Serve:
Once cooked, carefully remove the lid and garnish your casserole with chopped green onions and any extra bacon you’d like. Slice into pieces and serve warm for a delightful breakfast that everyone will love!
Enjoy a delicious, hearty breakfast that’s ready when you wake up!
Can I Use Different Types of Sausage?
Absolutely! You can substitute breakfast sausage with turkey sausage for a leaner option, or even a vegetarian sausage if you prefer. Just make sure it’s cooked before adding it to the casserole!
Is It Possible to Make This Recipe Dairy-Free?
Yes! You can use dairy-free milk (like almond or oat milk) and replace the cheddar and cottage cheese with dairy-free cheese alternatives. Just ensure the flavors align with your taste preference!
Can I Add Vegetables to the Casserole?
Definitely! Chopped vegetables like bell peppers, spinach, or mushrooms can be a great addition. Sauté them briefly before mixing them in, so they don’t release too much moisture during cooking.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. You can reheat individual portions in the microwave or oven until warmed through.
