Ingredients You’ll Need
Now that you’re excited about the Overnight Breakfast Casserole, let’s dive into the ingredients you’ll need to whip up this delicious dish. Don’t worry; it’s a straightforward list, and I promise you won’t need to hunt down any exotic items!
- 8 large eggs: The star of the show! Eggs provide the base for our casserole, giving it that fluffy, satisfying texture. You can use large or extra-large eggs, depending on what you have on hand.
- 1 cup heavy cream: This adds richness and creaminess to the casserole. If you’re looking for a lighter option, you can substitute half-and-half or even whole milk, but the texture might be a tad less decadent.
- 1 cup shredded cheddar cheese: Cheese makes everything better, right? Cheddar adds a sharp, tangy flavor that pairs beautifully with the other ingredients. Feel free to swap it for mozzarella or pepper jack if you want a different twist!
- 1 cup cooked and crumbled breakfast sausage: This is where the savory goodness comes in! You can use pork sausage, turkey sausage, or even a plant-based sausage if you’re looking for a vegetarian option.
- 1 cup chopped spinach (fresh or frozen, thawed and drained): Spinach adds a pop of color and a healthy dose of nutrients. If you’re using frozen spinach, just make sure to squeeze out the excess water after thawing.
- 1/2 teaspoon garlic powder: A little garlic goes a long way in enhancing the flavor. If you’re feeling fancy, you can use fresh minced garlic instead—just adjust the amount to your taste!
- 1/2 teaspoon onion powder: This adds a subtle sweetness and depth to the dish. You can also use finely chopped onions if you prefer a bit of crunch.
- 1/2 teaspoon salt: Essential for bringing out all the flavors. Adjust to your taste, especially if you’re using salty ingredients like cheese or sausage.
- 1/4 teaspoon black pepper: A dash of pepper adds a nice kick. If you like it spicy, feel free to add more!
- 1/4 teaspoon red pepper flakes (optional): For those who enjoy a little heat, these flakes are a great addition. If your family isn’t into spicy food, you can skip this.
- 1/4 cup chopped green onions (for garnish): These add a fresh, vibrant touch to your casserole when serving. You can also use fresh herbs like parsley or cilantro for a different flavor profile.
And there you have it! A simple yet flavorful lineup of ingredients that come together to create a breakfast masterpiece. If you’re looking for printable measurements, don’t worry! You’ll find them at the end of this article, ready for you to print and stick on your fridge for easy reference.
How to Make Overnight Breakfast Casserole
Now that you have all your ingredients ready, let’s get down to the fun part—making this Overnight Breakfast Casserole! I promise, it’s as easy as pie (or should I say, casserole?). Follow these simple steps, and you’ll have a delicious breakfast waiting for you in no time!
Step 1 – Prep Ingredients
First things first, let’s get our ingredients prepped. Start by gathering everything you need on your kitchen counter. It’s like setting the stage for a cooking show, and you’re the star!
Crack those 8 large eggs into a large mixing bowl. If you’re feeling a bit fancy, you can whisk them in a separate bowl first, but I usually just go for it in one big bowl. Next, pour in 1 cup of heavy cream. This is where the magic happens, adding that creamy goodness to our casserole.
Now, let’s chop up our spinach if you’re using fresh. If you’re using frozen, make sure it’s thawed and drained well. You don’t want any excess water ruining your casserole! If you’re adding any extra veggies like bell peppers or mushrooms, chop those up too. It’s all about making this dish your own!
Finally, if you’re using fresh garlic or onions instead of the powders, go ahead and mince those. You want everything ready to go so that when it’s time to mix, you can do it in a flash!
Step 2 – Begin Cooking
With your ingredients prepped, it’s time to mix! Grab that large mixing bowl with the eggs and cream, and whisk them together until they’re well combined. You want to see a lovely, frothy mixture that looks like it’s ready to party!
Now, it’s time to add in the fun stuff! Stir in the shredded cheddar cheese, cooked and crumbled breakfast sausage, and your chopped spinach. Sprinkle in the garlic powder, onion powder, salt, black pepper, and red pepper flakes if you’re feeling spicy. Mix everything together until it’s all evenly coated in that eggy goodness. It should look colorful and inviting—like a breakfast rainbow!
Step 3 – Combine Ingredients
Now that your mixture is ready, it’s time to transfer it to the baking dish. Grab your greased 9×13-inch baking dish and pour the egg mixture in. Use a spatula to spread it out evenly, making sure every corner is filled with that deliciousness.
Once it’s all in the dish, cover it tightly with plastic wrap. This is where the overnight magic happens! Pop it in the fridge and let it chill out for at least 4 hours, or preferably overnight. This allows all those flavors to meld together, creating a breakfast that’s bursting with taste!
Step 4 – Finish and Serve
When morning rolls around, it’s time to bake! Preheat your oven to 350°F (175°C). While it’s heating up, take the casserole out of the fridge and remove the plastic wrap. You don’t want to bake it with that on—trust me, it won’t end well!
Once the oven is ready, pop the casserole in and let it bake for 30-35 minutes. You’ll know it’s done when the top is golden brown and the casserole is set in the middle. The aroma wafting through your kitchen will be enough to make everyone’s mouths water!
After it’s baked to perfection, let it cool for a few minutes before slicing it into squares. Garnish with chopped green onions for that extra pop of color and flavor. Serve it warm, and watch as your family digs in with smiles on their faces. You’ve just created a breakfast masterpiece that’s sure to become a family favorite!
Tips for Perfect Results
Now that you’re all set to make your Overnight Breakfast Casserole, let me share some of my favorite tips to ensure you get perfect results every time. These little nuggets of wisdom can make a big difference, especially when you’re juggling a busy schedule!
- Enhance flavor with additional spices or herbs: Don’t be afraid to get creative! Add a pinch of smoked paprika for a smoky kick, or toss in some fresh herbs like basil or parsley for a burst of freshness. A dash of hot sauce can also elevate the flavor profile if your family enjoys a bit of heat!
- Speed up prep by using pre-cooked sausage or frozen spinach: If you’re short on time, consider using pre-cooked sausage crumbles. They’re a lifesaver! Just toss them in, and you’re good to go. Frozen spinach is also a great shortcut—just make sure to thaw and drain it well to avoid excess moisture.
- Store leftovers properly for easy reheating: If you happen to have leftovers (which is rare in my house!), store them in an airtight container in the fridge. They’ll keep for about 3-4 days. When you’re ready to enjoy them again, simply pop a slice in the microwave for a quick reheat. It’s like having a homemade breakfast ready to go at a moment’s notice!
With these tips in your back pocket, you’ll be well on your way to mastering the art of the Overnight Breakfast Casserole. Happy cooking!
Essential Equipment Needed
Before you dive into making your Overnight Breakfast Casserole, let’s make sure you have all the right tools on hand. Trust me, having the right equipment can make the cooking process smoother and more enjoyable. Here’s what you’ll need:
- 9×13-inch baking dish: This is the star of the show! A standard size for casseroles, it allows for even cooking and easy serving. If you don’t have one, a similar-sized dish will work, or you can use two smaller dishes to divide the mixture.
- Mixing bowls: You’ll need a couple of these for whisking your eggs and combining ingredients. If you’re short on bowls, a large pot can double as a mixing bowl in a pinch!
- Whisk: A good whisk is essential for blending the eggs and cream smoothly. If you don’t have one, a fork will do the trick, though it might take a bit more elbow grease!
- Plastic wrap: This is crucial for covering your casserole while it chills in the fridge. If you prefer, you can use a lid if your baking dish has one, or even a clean kitchen towel to cover it.
- Cooking spray or butter for greasing: You’ll want to grease your baking dish to prevent sticking. If you’re out of cooking spray, a little olive oil or melted butter brushed on with a paper towel works just as well!
With these essential tools at your disposal, you’re all set to create a delicious Overnight Breakfast Casserole that will make your mornings a breeze. Happy cooking!

Now that you’ve got the basics down, let’s talk about how to make this Overnight Breakfast Casserole your own! One of the best things about this dish is its versatility. You can easily tweak the ingredients to suit your family’s tastes or dietary needs. Here are some delicious variations to consider:
- Add diced bell peppers or mushrooms for extra veggies: If you’re looking to sneak in more nutrients, consider adding some colorful diced bell peppers or earthy mushrooms. They not only enhance the flavor but also add a lovely texture. Just sauté them lightly before mixing them in to bring out their natural sweetness!
- Substitute turkey sausage for a leaner option: If you’re trying to cut back on fat or calories, swapping out pork sausage for turkey sausage is a fantastic option. It still provides that savory flavor we all love, but with less grease. Plus, it’s a great way to keep things light without sacrificing taste!
- Make it gluten-free by ensuring all ingredients are certified gluten-free: For those with gluten sensitivities, this casserole can easily be made gluten-free. Just double-check that your sausage and any other packaged ingredients are labeled gluten-free. You can enjoy this hearty breakfast without any worries!
