How to Make Sausage and Egg Casserole – Step by Step

Step 1: Prepare Your Ingredients

1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking dish.
2. Cut bread into 1-inch cubes and set aside.
3. Measure out all remaining ingredients for easy assembly.

Step 2: Cook the Sausage

1. In a large skillet over medium heat, cook the breakfast sausage until no longer pink, breaking it into small pieces as it cooks (about 5-7 minutes).
2. If using vegetables, add bell pepper and onion to the skillet during the last 3 minutes of cooking and sauté until softened.
3. Drain excess grease from the sausage mixture.

Step 3: Assemble the Casserole

1. Spread the cubed bread evenly across the bottom of the greased baking dish.
2. Sprinkle the cooked sausage mixture over the bread layer.
3. Distribute 1½ cups of shredded cheese evenly over the sausage layer.

Step 4: Prepare the Egg Mixture

1. In a large bowl, whisk together the eggs, milk, salt, pepper, dried mustard powder, and garlic powder until well combined.
2. For a silkier texture, whisk vigorously for 1-2 minutes to incorporate air into the mixture.

Step 5: Combine and Bake

1. Pour the egg mixture evenly over the layers in the baking dish, ensuring all bread pieces are soaked.
2. Top with the remaining 1/2 cup of shredded cheese.
3. For immediate baking: Bake at 350°F for 35-40 minutes until the center is set and the top is golden brown.
4. For overnight preparation: Cover the dish with plastic wrap and refrigerate for up to 24 hours. When ready to bake, remove from refrigerator 30 minutes before baking, then follow the same baking instructions.

Step 6: Finish and Serve

1. Check doneness by inserting a knife in the center – it should come out clean with no runny egg.
2. Allow the casserole to rest for 5-10 minutes before serving.
3. Garnish with fresh herbs if desired.
4. Cut into squares and serve warm.

Pro Tips for Making the Best Sausage and Egg Casserole

• Use day-old or slightly stale bread for the best texture – it absorbs the egg mixture better without becoming soggy.
• Don’t skip the resting time after baking – this allows the casserole to set properly for easier serving.
• For a richer flavor, use half-and-half or cream instead of milk.
• Create a custom flavor profile by using different cheese varieties (Gruyère, pepper jack, or Swiss all work beautifully).
• For a spicier version, use hot Italian sausage or add a diced jalapeño.
• Test for doneness carefully – overbaking can result in a dry casserole.
• Can I make this ahead of time? Yes! This sausage and egg casserole is perfect for preparing the night before.
• What is the secret to a moist egg casserole? Don’t overbake and use enough milk in your egg mixture.

FAQs for Sausage and Egg Casserole

Can I freeze sausage and egg casserole?

Yes! This breakfast casserole freezes exceptionally well. Either freeze the entire unbaked casserole (thaw completely before baking) or freeze baked portions for quick individual breakfasts. When properly stored in an airtight container or wrapped tightly, it will keep for up to 2 months in the freezer.

What can I use instead of pork sausage in egg casserole?

You have several options: turkey sausage for a leaner alternative, chicken sausage for a different flavor profile, or vegetarian sausage crumbles for a meatless version. The key is ensuring your substitute is well-seasoned, as the sausage provides much of the flavor in this dish.

How do I know when my egg casserole is done?

A perfectly cooked sausage and egg casserole should be slightly puffed, golden brown on top, and set in the center. Insert a knife into the middle – it should come out clean without any runny egg mixture. The internal temperature should reach 160°F for food safety.

Can I make sausage and egg casserole without bread?

Absolutely! For a low-carb or gluten-free version, simply omit the bread. You can substitute with 2 cups of diced cooked potatoes, or for a keto-friendly option, add extra vegetables like bell peppers, spinach, and mushrooms to bulk up the casserole without adding carbs.
