Let’s Get Cooking!

Before we dive into the step-by-step process of making this Classic Egg Casserole Recipe, gather your ingredients. This simple yet flavorful breakfast casserole comes together with pantry staples, making it an easy go-to dish for any occasion.

Ingredients for Classic Egg Casserole Recipe

Meat

✔ 1 lb beef sausage (choose mild or spicy depending on your taste).

Egg Mixture

✔ 8 large eggs
✔ 2 cups whole milk
✔ ½ cup heavy cream
✔ 1 tsp salt
✔ ½ tsp black pepper
✔ ½ tsp garlic powder
✔ ½ tsp onion powder

Bread

✔ 6 cups cubed, day-old bread (or lightly toasted bread for extra texture).

Cheese

✔ 1 cup shredded cheddar cheese
✔ 1 cup shredded mozzarella cheese

Optional Garnish

✔ ¼ cup chopped green onions (adds a pop of color and flavor).

Step 1: Preheat and Prepare

First things first, preheat your oven to 350°F (175°C). While the oven is warming up, lightly grease a 9×13-inch baking dish. Trust me, you don’t want to skip this step—nobody loves scrubbing stuck-on casserole bits later! Proper greasing ensures that your Classic Egg Casserole Recipe comes out easily with perfect, golden edges.

Step 2: Cook the Sausage

Next, grab a large skillet and cook the beef sausage over medium heat. The goal is to get it beautifully browned and crumbly, bringing out a depth of flavor while ensuring the sausage is fully cooked before it mingles with the other ingredients. Once done, drain any excess grease and set the sausage aside.

🔹 Pro Tip: Want a lighter twist? Try swapping the beef sausage for turkey sausage or even a plant-based alternative—this simple swap makes your Classic Egg Casserole Recipe a bit healthier while keeping all the delicious flavors intact.

Step 3: Whisk Up the Egg Mixture

Now comes the creamy goodness! In a large mixing bowl, whisk together:
✔ 8 large eggs
✔ 2 cups whole milk
✔ ½ cup heavy cream
✔ 1 tsp salt
✔ ½ tsp black pepper
✔ ½ tsp garlic powder
✔ ½ tsp onion powder

This rich, savory egg mixture forms the backbone of your Classic Egg Casserole Recipe, ensuring every bite is packed with flavor.

🔹 Pro Tip: Want to enhance the flavor even more? Add a pinch of smoked paprika for a subtle smokiness or a dash of hot sauce for a slight kick!

Step 4: Time to Assemble Your Classic Egg Casserole Recipe

Here’s where the magic happens!

1️⃣ Layer the cubed bread evenly in the prepared baking dish—think of it as the foundation of your Classic Egg Casserole Recipe.
2️⃣ Spread the cooked sausage over the bread, ensuring every bite gets a bit of that savory, seasoned goodness.
3️⃣ Pour the egg mixture over the bread and sausage, then gently press down to make sure all the bread cubes are soaked—this step is key to achieving a moist and flavorful casserole.
4️⃣ Sprinkle the shredded cheddar and mozzarella cheese over the top. This final layer will melt into a golden, bubbly, cheesy topping that makes this Classic Egg Casserole Recipe truly irresistible!

Baking Your Classic Egg Casserole Recipe to Perfection

Now that your Classic Egg Casserole Recipe is beautifully assembled, it’s time to pop it into the oven and let those flavors meld together into something truly irresistible. This step is where all the rich, creamy, cheesy goodness comes to life, resulting in a golden, fluffy, and satisfying breakfast casserole. The aroma alone will have everyone eagerly waiting at the table!

Step 5: Into the Oven

To ensure your Classic Egg Casserole Recipe bakes perfectly, follow these steps carefully:

1️⃣ Cover the casserole dish with aluminum foil, making sure it’s snug around the edges. This crucial step traps in moisture, allowing the eggs to cook evenly while preventing the top from browning too quickly.

2️⃣ Place the dish in your preheated oven (350°F/175°C) and bake for 30 minutes. During this time, the eggs will begin to firm up, and the flavors will start to blend beautifully.

3️⃣ After 30 minutes, remove the foil to allow the casserole to develop that beautiful golden-brown crust on top. This final stage of baking enhances the texture, giving you a slightly crispy, cheesy topping with a soft, creamy center.

4️⃣ Continue baking uncovered for another 15–20 minutes. Keep an eye on the casserole during this time—the cheese should turn golden and bubbly, and the edges should be slightly crisp.

5️⃣ Check for doneness by gently pressing the center with a fork or inserting a skewer. If it comes out clean and the center feels firm, your Classic Egg Casserole Recipe is ready to serve! If it still looks slightly runny, bake for an additional 5 minutes, checking frequently.

🔹 Pro Tip: Short on time? You can speed up the baking process by increasing the oven temperature to 375°F (190°C) and reducing the covered baking time to 25 minutes. However, be sure to monitor closely to prevent over-browning!

Step 6: Let It Rest – A Crucial Final Step

As tempting as it may be to dive right in, giving your Classic Egg Casserole Recipe a few minutes to rest is crucial for the best texture and flavor.

✔ Allow the casserole to cool for at least 5–10 minutes before slicing. This allows the eggs to firm up slightly, making it easier to serve clean, structured portions instead of a runny mess.

✔ During this time, the cheese will continue melting and setting, giving you that perfect gooey, cheesy bite in every forkful.

✔ Serving tip: While waiting for the casserole to rest, prepare some fresh garnishes like chopped green onions, fresh parsley, or crumbled bacon for a final burst of color and flavor.

🔹 Pro Tip: If you’re making this Classic Egg Casserole Recipe for a large gathering, consider baking two at the same time in separate dishes. This ensures even cooking and gives you plenty of servings for everyone!

Serving Suggestions for Your Classic Egg Casserole Recipe

Now that your Classic Egg Casserole Recipe is beautifully baked to golden perfection, it’s time to serve it up in style! Whether you’re preparing a quick weekday breakfast or a special weekend brunch, these serving ideas will take your dish to the next level.

How to Serve Your Classic Egg Casserole Recipe

1️⃣ Slice It Perfectly
Once the casserole has rested, cut it into squares or rectangles, depending on the size of your baking dish. This makes serving easy and ensures everyone gets a hearty portion.

2️⃣ Add a Fresh Garnish
For a finishing touch, sprinkle chopped green onions over the top. This adds:
✔ A pop of vibrant color
✔ A mild oniony kick that enhances the dish’s flavor
✔ A restaurant-quality presentation that makes your Classic Egg Casserole Recipe even more irresistible!

🔹 Pro Tip: Not a fan of green onions? Try garnishing with chopped fresh parsley, crispy bacon bits, or a sprinkle of smoked paprika for extra flavor and visual appeal!

What to Serve with Classic Egg Casserole Recipe

While this Classic Egg Casserole Recipe is a complete meal on its own, pairing it with the right sides can enhance the experience and create a well-rounded breakfast.

✔ Fresh Fruit – A side of mixed berries, sliced oranges, or a fruit salad balances the richness of the casserole with a refreshing sweetness.
✔ Simple Green Salad – A light salad with arugula, cherry tomatoes, and a lemon vinaigrette adds a crisp contrast to the creamy eggs and cheese.
✔ Toast or Biscuits – Serve with buttery toast, flaky biscuits, or even croissants for an extra indulgent breakfast.
✔ Hash Browns or Roasted Potatoes – If you’re craving something heartier, crispy hash browns or seasoned roasted potatoes pair beautifully with the cheesy egg casserole.
✔ Avocado Slices – Creamy avocado with a sprinkle of salt and pepper complements the dish while adding healthy fats.

Beverage Pairings for the Perfect Breakfast

To complete your Classic Egg Casserole Recipe meal, don’t forget a refreshing drink!

☕ Hot Coffee or Cappuccino – The bold flavors of coffee contrast beautifully with the rich, cheesy, and savory notes of the casserole.
🍊 Fresh-Squeezed Orange Juice – A glass of OJ adds a naturally sweet, citrusy touch to brighten up your meal.
🥤 Smoothies – A banana, strawberry, or green smoothie makes a delicious and nutritious addition.
🍵 Iced Tea or Herbal Tea – If you prefer tea, a mint or chamomile tea can be a soothing choice to balance the hearty flavors of the dish.

Tips for the Best Classic Egg Casserole Recipe Every Time

Want to ensure your Classic Egg Casserole Recipe turns out perfectly fluffy, flavorful, and satisfying every single time? These expert tips will help you elevate your casserole game and impress your family with every bite!

1. Use Stale or Toasted Bread for the Best Texture

✔ Why? Day-old bread absorbs the egg mixture better, giving your casserole a rich, custard-like texture without becoming soggy.
✔ How to fix fresh bread? If your bread is too fresh, lightly toast it in the oven at 300°F (150°C) for 5–7 minutes before assembling your Classic Egg Casserole Recipe.

🔹 Pro Tip: Try using sourdough, whole wheat, or brioche for a unique flavor twist!

2. Customize the Cheese for Maximum Flavor

While cheddar and mozzarella are classic choices for this Classic Egg Casserole Recipe, you can get creative with different cheeses:

✔ Pepper Jack – Adds a spicy kick for those who love bold flavors.
✔ Gouda or Smoked Cheddar – Infuses the casserole with a smoky, rich depth.
✔ Swiss or Gruyère – Brings a mild, nutty taste that complements eggs perfectly.

🔹 Pro Tip: Want a super cheesy casserole? Mix two or three cheeses for a more complex, gooey texture!

3. Make It Ahead for Easy Mornings

✔ Busy mornings? Assemble your Classic Egg Casserole Recipe the night before and refrigerate it overnight.
✔ The longer the bread soaks in the egg mixture, the more flavorful and cohesive your casserole will be.

🔹 Pro Tip: If baking straight from the fridge, let the casserole sit at room temperature for 15 minutes before placing it in the oven. This ensures even baking and prevents the dish from being too cold in the center.

4. Add Vegetables for Extra Nutrition & Color

Want to sneak in more nutrients without sacrificing flavor? Toss in some veggies to enhance the color, texture, and nutritional value of your Classic Egg Casserole Recipe.

✔ Diced bell peppers – Add sweetness and crunch.
✔ Sautéed mushrooms – Enhance the umami flavor.
✔ Spinach or kale – A great way to add greens without overpowering the dish.
✔ Onions and tomatoes – Bring natural sweetness and acidity to balance the richness.

🔹 Pro Tip: Sauté harder vegetables before adding them to the casserole to ensure they cook evenly and don’t release too much moisture during baking.

5. Scale It Up or Down for Any Occasion

✔ Hosting a crowd? Double the recipe and bake it in two 9×13-inch dishes for a larger serving.
✔ Cooking for two? Halve the recipe and bake in an 8×8-inch pan for a smaller, more intimate breakfast.

🔹 Pro Tip: If making individual portions, divide the egg mixture into muffin tins for easy grab-and-go breakfast cups!

FAQs About Classic Egg Casserole Recipe

Here are answers to the most common questions about making this Classic Egg Casserole Recipe perfectly every time!

Yes! Assemble it the night before, cover, and refrigerate. Let it sit at room temperature for 10–15 minutes before baking.
