How to Make Sausage and Egg Casserole
-
Preheat your oven to 375°F (190°C). This ensures that your casserole cooks evenly and reaches that delightful golden brown crust everyone loves. Lightly grease a 7×11-inch (or 8×11-inch) baking dish with butter or nonstick spray to prevent sticking.
-
Brown the sausage in a skillet over medium heat, breaking it into small crumbles. This step infuses the dish with savory goodness. Once browned, drain any excess grease and set it aside to cool slightly.
-
Whisk together in a large bowl the eggs, milk, salt, pepper, garlic powder, and smoked paprika. The mixture should be smooth and well combined—this is what brings all your casserole ingredients together!
-
Layer the cooked sausage, optional vegetables, and shredded cheese in the greased baking dish. If you’re using bread cubes, sprinkle them on top for added texture. Finally, pour the egg mixture evenly over the top to make sure everything is integrated beautifully.
-
Bake for 30-40 minutes, or until the center is set and the top is golden brown. The irresistible smell will fill your kitchen, making it hard to wait!
-
Let cool for 5 minutes before slicing. This allows the casserole to set, making it easier to serve. Enjoy it warm for the best taste experience!
Optional: Serve with a dollop of salsa or hot sauce for an extra kick!

Make Ahead Options
These Sausage and Egg Casserole preparations are perfect for busy weeks! You can cook the sausage and mix the egg mixture for up to 24 hours in advance, refrigerating them separately to maintain freshness. If you’re using any vegetables, chop those ahead too. On the day you plan to serve, simply layer everything in your greased baking dish and pour the egg mixture over; then bake right before enjoying! For optimal flavor and texture, avoid adding the bread cubes until you’re ready to bake, as this will prevent sogginess. With this make-ahead approach, your hearty breakfast dish will be just as delicious and satisfying without the morning rush.

Chef's Helpful Tips
- For your Sausage and Egg Casserole, be sure to brown the sausage completely to enhance the flavor before mixing it with other ingredients.
- Avoid overfilling your baking dish to allow the casserole to rise properly; a dish that is too full can prevent even cooking.
- Whisk the egg mixture until you achieve a uniform consistency, as this will ensure that every bite is flavorful and cohesive.
- Bake the casserole until the top is golden brown and the center has set, which usually takes about 30-40 minutes; check for doneness by inserting a knife in the center – it should come out clean.
Sausage and Egg Casserole Recipe FAQs
How do I choose the right sausage for my casserole?
Absolutely! When selecting a breakfast sausage, consider your taste preference. You can opt for mild, spicy, or even Italian sausage to add a unique twist. For the best flavor, choose fresh sausage from your local butcher or grocery store, and ensure it hasn’t got any dark spots or an off smell.
What’s the best way to store leftovers?
You can keep your Sausage and Egg Casserole in an airtight container in the fridge for up to 3 days. Make sure to let it cool down completely before sealing it up; this prevents excess moisture from accumulating. If you want to keep it longer, freezing is a great option!
Can I freeze Sausage and Egg Casserole?
Yes! I often recommend freezing individual portions of your Sausage and Egg Casserole for later enjoyment. Wrap each portion tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can last up to 2 months in the freezer. To reheat, simply defrost overnight in the fridge and then warm it up in a preheated oven at 350°F (175°C) for about 15-20 minutes.
What if my casserole isn’t cooking evenly or is too soggy?
Very! If your casserole is not cooking evenly, ensure you’re not overfilling your baking dish; it’s best to leave some space for rising. If it turns out too soggy, it might be due to excess liquid from vegetables or milk. To counter this next time, squeeze out extra moisture from veggies like spinach, and avoid adding too many wet ingredients.
Is this recipe suitable for people with dietary restrictions?
Absolutely! You can tailor the Sausage and Egg Casserole to fit various dietary needs. For gluten-free options, use gluten-free bread cubes or skip them altogether. If you’re dealing with dairy allergies, substitute cow’s milk with almond, oat, or coconut milk, and select a dairy-free cheese. Just keep in mind the changes in texture and flavor depending on the substitutions you use.
Can my pets eat the sausage from this recipe?
It’s best to avoid giving the sausage directly to pets, as it might contain spices and additives that are harmful to them. Always check with your vet before sharing human food with your furry friends, to ensure it’s safe for their diet!
