How to Make Sausage Breakfast Casserole
Phase 1 – Prep
- Preheat your oven to 350°F (175°C).
- In a large skillet, cook the ground sausage over medium heat until fully browned. Drain any excess fat.
- While the sausage cooks, prepare a 9×13-inch baking dish with cooking spray or butter.
- In a mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until smooth.
Phase 2 – Cook/Assemble
- Spread the thawed hash browns evenly across the bottom of your prepared baking dish.
- Layer the cooked sausage on top of the hash browns, then sprinkle the onions and bell peppers evenly.
- Pour the egg mixture over the layers, ensuring it coats all ingredients.
- Finally, sprinkle the shredded cheese evenly over the top.
- Bake in the preheated oven for 45-50 minutes, or until the edges are golden and the center is set.
Phase 3 – Serve
- Remove the casserole from the oven and allow it to cool for 5-10 minutes.
- Slice into squares and serve warm.
- For an extra touch, add toppings like fresh herbs, avocado slices, or a dollop of sour cream.
Pro Tips for the Best Results
- Sauté the Vegetables: Sauté onions and peppers before adding them to the casserole to enhance their sweetness.
- Cheese Swap: Try different cheeses like feta for a tangy twist or mozzarella for a milder flavor.
- Storage Solution: Make extra and store leftovers in individual portions for easy breakfasts throughout the week.
Common Mistakes to Avoid
- Overcooking the Sausage: If you cook the sausage too long, it can become dry. Aim for browned but not crispy; it will continue cooking in the oven.
- Not Thawing Hash Browns: Cooking frozen hash browns directly will make the casserole watery. Always ensure they are completely thawed and well-drained if necessary.
- Skipping Cooling Before Serving: Cutting into a hot casserole makes it fall apart. Letting it rest for a few minutes helps it firm up for cleaner slices.
Recipe Variations
- Gluten-Free: Use gluten-free hash browns.
- Dairy-Free: Substitute with dairy-free cheese and plant-based milk.
- Spicy: Add diced jalapeños or red pepper flakes for some heat.
- Herbal: Toss in fresh herbs like parsley or chives for added freshness.
- Instant Pot: Cook in an Instant Pot for a quicker version (adjust time accordingly).
How to Serve Sausage Breakfast Casserole
- Best Pairings: Fresh fruit salad or crispy bacon complements this dish nicely.
- Toppings: Add a sprinkle of fresh herbs, avocado slices, or salsa for a zesty kick.

Reheating
To reheat, place slices in the oven at 350°F for about 15-20 minutes or microwave for 1-2 minutes, stirring halfway for even warming.
FAQs
Can I use frozen cauliflower instead of hash browns? Yes, frozen cauliflower works, but it may change the texture. Drain well!
