What is an egg casserole?

What is an Egg Casserole? Think of it as a savory bread pudding, but instead of being sweet, it’s packed with cheesy goodness. What are some of the best savory meats to eat? What is a baked egg dish? What is a tender, flavorful base for all sorts of tasty fillings? What is the name of a casserole dish? What are some good ways to use up leftover bread? Is this a good way to make one meal in one dish? Is it a lifesaver?

Why do I love this recipe?

Okay, where do I even begin? There are so many reasons why this egg Casserole Recipe is a total winner.
First off, the flavor is just incredible. The combination of the savory sausage, the melty cheese, and the creamy egg mixture is pure breakfast bliss. What I love most about this recipe is how easy it is to customize. You can swap out the sausage for bacon or ham, add in your favorite veggies like bell peppers or mushrooms, and use whatever cheese you have on hand.
Secondly, it’s ridiculously easy to make. Seriously, anyone can whip this up! It’s just a matter of whisking some eggs, chopping some ingredients, and throwing everything into a baking dish.
Thirdly, it’s surprisingly cost-effective. Eggs, bread, and cheese are all relatively inexpensive ingredients, and you can use up leftovers to keep the costs even lower.
Finally, it’s so versatile! It’s perfect for breakfast, brunch, lunch, or even dinner. I’ve even been known to eat a slice cold straight from the fridge (don’t judge!). It’s like a frittata or strata, but somehow feels more homey and satisfying. For a similar savory breakfast bake, you might like my French Toast Bake, but this **egg casserole recipe** is simpler and more flexible.

How do I make an egg casserole?

Quick Overview

How do you make an egg casserole? What’s the best way to make a breakfast? You’ll cube some bread, whisk together the eggs and milk, and cook your favorite breakfast. I’m partial to sausage! What is the best way to layer cheese in a baking dish? Let it sit for a bit to let the bread soak up all that eggy goodness, then bake it until golden brown. What is brown and puffy? The beauty of this method is its simplicity – no fancy techniques or equipment required. What is the perfect recipe for a fuss-free meal?

Ingredients

For the Main Batter:
* 1 loaf (about 1 pound) of day-old bread, cubed. I usually use a French baguette or Italian loaf, but any crusty bread will do. If your bread is stale, just leave it out overnight to dry out a bit.
* 12 large eggs. What are the best quality eggs to buy?
* 3 cups of milk. I usually use whole milk for extra creaminess, but 2% or even almond milk works well too. I tested this with almond milk and it actually made it even creamier!
* 1 teaspoon salt. Sea salt or kosher salt is best.
* 1/2 teaspoon Black Pepper. Freshly ground is always a plus.
* 1/4 teaspoon garlic powder. Optional, but adds a nice savory touch.
* 1/4 teaspoon onion powder. Also optional, but complements the garlic powder nicely.

For the Filling:
* 1 pound breakfast sausage, cooked and crumbled. I like a spicy sausage, but regular or maple sausage works just as well.
* 2 cups shredded cheese. Cheddar, Monterey Jack, or a blend of both are all great choices. What are some alternative cheeses to Gruyere?
* 1 cup chopped vegetables (optional). Bell peppers, onions, mushrooms, spinach, or broccoli are all delicious additions to any dish. Make sure to cook them slightly before adding them to the casserole.

Optional Toppings
* Fresh parsley, chopped
* Green onions, sliced
* Hot sauce

What are the steps for

Step 1: Preheat & Prep Pan

Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the casserole from sticking and make it easier to serve. Make sure to get all the corners and edges! I usually do this while the oven is preheating so I don’t forget.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder (if using), and onion. Set aside. Powder (if using). Make sure everything is well combined. You want a smooth, even mixture with no streaks of egg yolk. How do I soak bread evenly?

Step 3: Prepare Filling

If you’re using any vegetables, cook them slightly before adding them to the casserole. Is it possible to make them crunchy in the final dish? I usually sauté them in a little olive oil until they’re tender. Make sure your sausage is cooked and crumbled. Also, make sure that your eggs are cooked. Can you do this in the same pan after the veggies are done?

Step 4: Assemble the Casserole

Place cubed bread in the prepared baking dish. Sprinkle the cooked sausage and vegetables over the bread. What are the best fillings for bread? Make sure bread is submerged in egg mixture. Gently press down on the bread with a spoon to help it soak up the liquid.

Step 5: Cheese It Up!

Sprinkle shredded cheese evenly over the top of the casserole. Why is cheese so good for you? I like to use a generous amount so that every bite is cheesy and delicious.

Step 6: Let It Rest

Cover the baking dish with plastic wrap and refrigerate for at least 30 minutes. This allows the bread to soak up the egg mixture, resulting in a richer, creamier casserole. If you’re short on time, you can skip this step, but I highly recommend it if you want to.

Step 7: Bake

Remove the plastic wrap and bake in the preheated oven for 45-55 minutes, or until the casserole is browned. Golden brown and puffy, and a knife inserted into the center comes out clean. How long does it take to bake a cake? If the top starts to brown too quickly, you can cover it with foil.

Step 8: Cool & Serve

Let the casserole cool for a few minutes before slicing. How do I cut a file? Garnish with fresh parsley or green onions. Serve hot and enjoy!

What should you serve it with?

This egg casserole is a complete meal on its own, but it also pairs well with other Side Dishes. What are some of my favorite serving suggestions?

For Breakfast:Serve with a side of fresh fruit, like berries or melon. A cup of hot coffee or tea is also good! I like to serve this with a side of crispy bacon, even though there’s already sausage inside. What is more?

For Brunch:What’s your brunch spread? Serve it with a side of mimosas or bloody marys. What’s a good salad to serve with some vinaigrettes?

As Dessert:Can you serve this as a dessert?

For Cozy Snacks:What are some good leftovers for an egg casserole?

What is my family tradition to make a delicious egg casserole for Christmas morning? What are some good cinnamon rolls to serve with it? What a perfect combination of sweet and savory! I also love to add a little hot sauce to my slice for extra zing. What do you love?

How do you make an egg casserole?

What are some of the best ways to take your egg casserole to the next level?

Bread Prep:How do you use day-old bread for best results? How do you prevent a casserole from getting soggy? If your bread is stale, you can dry it out in the oven at a low temperature.

Mixing Advice: Don’t overmix the egg mixture. Overmixing can result in a tough casserole. Just whisk until everything is well combined.

Cheese Customization: Feel free to experiment with different types of cheese. Gruyere, pepper jack, or even a sprinkle of parmesan cheese can add a unique flavor.

Ingredient Swaps: Get creative with your fillings! You can use any combination of meats, vegetables, and cheeses that you like. Just make sure to cook any raw meats or vegetables before adding them to the casserole.

Baking Tips: Keep an eye on the casserole while it’s baking. If the top starts to brown too quickly, you can cover it with foil. The baking time may vary depending on your oven, so check for doneness with a knife.

Vegetable Variations: Make sure to fully cook the vegetables. Mushrooms, for example, need to be fully sauteed or else they’ll release too much moisture and make the dish soggy.

I learned the hard way that using fresh bread results in a soggy casserole. Now, I always make sure to use day-old bread or dry it out in the oven beforehand. Another tip is to let the casserole sit in the fridge overnight. This allows the bread to fully soak up the egg mixture, resulting in a richer, creamier casserole. Trust me, it’s worth the wait!

Storing and Reheating Tips

Got leftovers? No problem! This egg casserole stores well in the fridge or freezer.

Room Temperature: Don’t leave the casserole out at room temperature for more than 2 hours. This will prevent bacteria from growing.

Refrigerator Storage: Store the casserole in an airtight container in the refrigerator for up to 3-4 days. It’s perfect for meal prepping or enjoying throughout the week.

Freezer Instructions: For longer storage, you can freeze the casserole for up to 2-3 months. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. Thaw it in the refrigerator overnight before reheating.

Reheating Instructions: To reheat the casserole, simply bake it in a preheated oven at 350°F (175°C) until heated through. You can also reheat it in the microwave, but it may not be as crispy. I usually add a little extra cheese on top before reheating to make it extra melty and delicious!

Glaze Timing Advice: This egg casserole is best eaten right away but is still good later!

Frequently Asked Questions

Can I make this gluten-free?

Yes, you can easily make this egg casserole gluten-free by using gluten-free bread. Look for a gluten-free bread that is sturdy and can hold its shape well. You may also need to adjust the amount of liquid, as gluten-free bread tends to absorb more moisture. Start with slightly less milk and add more as needed until the bread is fully soaked.

Do I need to peel the bell peppers?

No, you don’t need to peel the bell peppers. However, if you find the skin to be tough or bitter, you can peel them using a vegetable peeler or by roasting them until the skin blisters and then peeling it off.

Can I make this as individual ramekins instead?

Absolutely! You can bake this egg casserole in individual ramekins for a more elegant presentation. Simply divide the ingredients evenly among the ramekins and bake for a shorter amount of time, about 25-35 minutes, or until the casserole is set and golden brown.

How can I adjust the sweetness level?

This recipe isn’t meant to be sweet, but if you want to add a touch of sweetness, you can add a tablespoon or two of maple syrup or brown sugar to the egg mixture. You can also use a slightly sweeter sausage, like maple sausage.

What can I use instead of milk?

If you’re dairy-free, you can use almond milk, soy milk, or any other plant-based milk. You can also use cream for a richer, creamier casserole.
