Ingredients You’ll Need
Ingredient | Amount |
---|---|
Breakfast sausage (e.g., Jimmy Dean) | 1 lb. |
Red bell pepper, chopped | 1 medium |
Green onions, chopped (white and green parts divided) | 4 |
Eggs | 10 large |
Heavy cream | 1 1/4 cups |
Dijon mustard | 1 tbsp. |
Hot sauce (optional) | 2 tsp. |
Salt | 1 1/2 tsp. |
Black pepper | 1 tsp. |
Shredded sharp cheddar cheese, divided | 2 cups |
Frozen shredded hash browns, thawed | 1 (30-oz.) package |
Butter or nonstick spray | as needed |
Step-By-Step Instructions
- Prepare Your Dish:
Preheat your oven to 350°F (175°C). Grease a 13-by-9-inch (or other 3-quart) baking dish with butter or a generous layer of nonstick cooking spray for hassle-free cleanup. - Cook the Sausage and Veggies:
In a large skillet over medium-high heat, add the breakfast sausage, breaking it up with a wooden spoon. Cook until there’s no pink left (about 6–8 minutes). Add the chopped red bell pepper and the white and light green parts of the green onions. Cook for an additional 3 minutes, stirring occasionally, then transfer the mixture to a plate and let it cool for a few minutes. - Mix the Egg Base:
In a large mixing bowl, whisk the eggs, heavy cream, Dijon mustard, hot sauce (if using), salt, black pepper, and about half of the remaining chopped green parts of the onions. Whisk until well combined so the mixture is light and uniform. - Combine Everything:
Gently fold 1 1/2 cups of the cheddar cheese, the thawed hash browns, and the cooled sausage mixture into the whisked egg mixture. Stir until everything is evenly distributed but don’t overmix, to keep the texture fluffy. - Assemble in the Baking Dish:
Pour the entire mixture into your prepared baking dish and smooth the top with a spatula for even cooking. - Bake the Casserole:
Cover the dish with foil and bake for 50 minutes. Remove the foil, sprinkle the remaining 1/2 cup of cheese over the top, and raise the oven temperature to 400°F (200°C). Continue baking for 10–15 minutes, until the cheese is melted and golden and the center of the casserole is set (not jiggly). - Finish and Serve:
Allow the casserole to rest for 10 minutes after baking. Sprinkle the remaining green onion tops over the casserole for a fresh burst of color and flavor, then serve hot.
Tips for the Perfect Sausage Breakfast Casserole
- Thaw Hash Browns Completely: Moisture from icy hash browns can make the casserole soggy. Spread them on paper towels to absorb excess moisture before combining.
- Use Quality Sausage: Choose a flavorful breakfast sausage you enjoy. Spicy or sage varieties can add more depth.
- Make-Ahead Instructions: Assemble the casserole the night before without baking, cover, and refrigerate. In the morning, let it come to room temperature for 20–30 minutes, then bake as directed.
- Test for Doneness: The center should be set—if it still jiggles, bake for an extra 5 minutes and check again.
Variations and Add-Ins
This casserole is endlessly customizable. Try these twists to keep breakfast exciting:
- Veggie Lovers: Add sautéed mushrooms, spinach, or zucchini for more color and flavor.
- Cheese Options: Swap cheddar for Monterey Jack, Swiss, pepper jack, or a blend.
- Meat Swaps: Substitute crumbled bacon, diced ham, or turkey sausage for variety.
- Herbs & Spices: Fresh parsley, chives, or a dash of smoked paprika bring brightness.
- Gluten-Free: Double-check that all packaged ingredients (like hash browns and sausage) are certified gluten-free.
Serving Suggestions
- Complete the Meal: Serve with fresh fruit, biscuits, or a simple green salad for a balanced breakfast.
- On the Go: Slice cooled casserole into squares—perfect for meal prep or reheating as a quick weekday breakfast.
Storing and Making Ahead
- Refrigerator: Leftovers keep in an airtight container for up to 4 days. Reheat individual portions in the microwave or oven.
- Freezer: Wrap baked casserole tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating in the oven at 350°F until heated through.
- Make Ahead: Assemble and refrigerate overnight (unbaked), then bake fresh in the morning for maximum flavor and texture.

Frequently Asked Questions (FAQs)
Q: Can I make this casserole vegetarian?
A: Yes, omit sausage and add more veggies such as mushrooms, spinach, or extra bell peppers. Use a vegetarian sausage substitute if you like.

A: Yes, grate russet potatoes, rinse, dry thoroughly, and measure about 3 1/2 cups for a fresh substitute.
