How To Make Sausage and Egg Casserole
Ready to assemble this hearty breakfast bake? In just a few simple steps, you’ll brown savory sausage, sauté sweet peppers and onions, whisk together a rich egg custard, fold in cubed bread, and let your oven work its magic. Follow the detailed instructions below to ensure each layer of flavour and texture comes together perfectly—then sit back and enjoy the golden, bubbling result.
1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter and set aside.
2. In a large skillet over medium heat, add the breakfast sausage. Break apart with a spatula and cook until browned and cooked through, about 8–10 minutes. Drain any excess fat to keep the casserole from becoming greasy.
3. Add the diced bell peppers and onions to the same skillet with the cooked sausage. Sauté until the vegetables are softened and fragrant, about 5 minutes. Remove from heat and set aside.
4. In a large mixing bowl, whisk together the eggs, milk, garlic powder, salt, black pepper, paprika, and dried thyme until smooth and well combined.
5. Add the cubed bread to the egg mixture and gently fold until each piece is coated in the custard.
6. Stir in the sausage and vegetable mixture, followed by the shredded cheddar cheese. Mix until everything is evenly distributed.
7. Pour the entire mixture into the prepared baking dish, spreading it out evenly with a spatula.
8. Bake in the preheated oven for approximately 30–40 minutes, or until the casserole is set in the middle and golden brown on top. Insert a knife in the center; it should come out clean.
9. Once baked, remove from the oven and let it rest for about 10 minutes before slicing and serving to ensure neat, firm slices.
Serving Suggestions
When this golden, bubbling masterpiece comes out of the oven, you’ll want to serve it in style. These ideas will help you balance flavours and textures, turning your breakfast or brunch into a memorable meal.
- Fresh fruit platter: Offer a colourful spread of berries, melon, or citrus segments to cut through the casserole’s richness.
- Simple green salad: Toss baby spinach or arugula with a light lemon vinaigrette for a crisp, refreshing contrast.
- Spicy hot sauce: Provide a drizzle or side of your favourite hot sauce to wake up each bite with zesty heat.
- Warm toast or English muffins: Toasted bread on the side lets guests scoop up every last cheesy, eggy morsel.
Tips For Perfect Sausage and Egg Casserole
This make-ahead bake is flexible and forgiving, but a few insider tricks will take it from good to unforgettable. Always use day-old bread for the ideal custardy texture without sinking into mush.

How To Store It
Proper storage keeps every slice of your sausage and egg casserole tasting fresh, whether you’re saving leftovers for later in the week or stashing portions for future breakfasts. Follow these methods to maintain flavour, texture, and safety.
- Refrigeration: Allow the casserole to cool to room temperature, then transfer individual slices into an airtight container. Store in the fridge for up to 4 days.
- Freezing: Wrap portions tightly in plastic wrap and aluminum foil, or use freezer-safe bags. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating in the Oven: Preheat oven to 350°F (175°C). Place a slice on a baking sheet and heat for 10–12 minutes until warmed through and slightly crisp on top.
- Microwave Method: Cover a portion with a damp paper towel and microwave on medium power for 1–2 minutes, pausing halfway to check for even heating.
Frequently Asked Questions
Got questions? Here are some quick answers to common queries about this sausage and egg casserole.
- How long does it take to prepare and bake this casserole?
A: The prep work—browning the sausage, chopping and sautéing vegetables, whisking eggs, and assembling—takes about 20–25 minutes. Bake at 350°F for 30–40 minutes, then let it rest for 10 minutes before slicing. In total, you’ll need around 60–75 minutes from start to finish.
- Can I assemble the casserole the night before?
A: Yes. After cooking the sausage, peppers, and onions, combine all ingredients in the greased baking dish, cover tightly with plastic wrap or foil, and refrigerate overnight. The next morning, remove the cover and bake as directed—this makes breakfast effortless.
- What type of bread works best, and can I use gluten-free alternatives?
A: Day-old or slightly stale bread—white, whole wheat, sourdough, or even cornbread—absorbs the egg mixture without turning mushy. For gluten-free, use a gluten-free loaf cut into cubes; baking time may vary slightly, so check for doneness with a clean knife insertion.
- How can I customize the flavor or add more vegetables?
A: Feel free to swap or add vegetables like chopped spinach, mushrooms, zucchini, or leftover stuffing. Sauté moisture-heavy veggies first to remove excess liquid. To boost flavor, experiment with cheeses (pepper jack, Gruyère) and herbs (rosemary, chives, oregano) or spices like red pepper flakes.
- How do I know when the casserole is fully baked?
A: The top should be golden brown and the edges slightly puffed. Insert a knife or toothpick into the center—if it comes out clean or with just a few moist crumbs, it’s done. Underbaking may leave the center runny, so bake until the middle is set.
- What’s the best way to store and reheat leftovers?
A: Store cooled leftovers in an airtight container in the fridge for up to 4 days. Reheat individual servings in the microwave for 1–2 minutes or in a 350°F oven for about 10 minutes. For longer storage, freeze portions for up to 2 months; thaw overnight in the refrigerator before reheating.
