Easy Breakfast Casserole

Easy Breakfast Casserole Ingredients

When all those ingredients come together and bake up, the flavor and texture are just amazing. It’s the kind of breakfast that fills you up and keeps you going all day long. It’s packed with nutrients, and the flavors all work together to make sure you’re set for a good day!

• Ground sausage – Sauté ground breakfast sausage over medium-high heat until it is browned in the skillet. Spoon excess grease out of the pan before adding the other ingredients. This is a meaty and delicious flavored sausage that we love to have in the egg mixture.
• Red pepper – Wash and chop the red bell peppers into small cube pieces. These give an extra soft crunch as you are enjoying your casserole for breakfast.
• Onion – Slice and chop the onion as little or big as you would like. This gives a delicious spice to the casserole.
• Hash brown potatoes – Either shredded or cubbed hash browns work great for this recipe. We use the frozen kind that is already freeze-dried. Freshly shredded or cubed potatoes will become soft and mushy in the oven with the egg mixture. We have even used tater tots with great results!
• Cheddar cheese – Shredded sharp cheddar cheese is sprinkled in the easy breakfast casserole.
• Eggs – This is one of the main ingredients that hold the other ingredients together while baking. Large or medium eggs work best.
• Milk – The creaminess from the milk fluffs up the eggs while baking.

How to Make Easy Breakfast Casserole

Trust me, once you try this breakfast casserole, it’s going to be your new favorite! It’s so simple to make, and you can have it ready in an hour. With protein, potatoes, veggies, and a savory egg mixture, it’s basically the breakfast of dreams!

1. Saute – Preheat oven to 350 degrees. Heat a large skillet over medium heat. Cook sausage, pepper, and onion until sausage is browned and vegetables are tender. Drain off any excess fat.
2. Combine – In a large bowl, combine the sausage mixture with hash browns and cheddar cheese. Pour into a greased 9×13 baking dish.
3. Whisk – In a separate bowl, combine eggs and milk. Whisk until fully blended. Pour over the hash brown mixture.
4. Bake – Place in the oven and bake at 350 degrees for 50-60 minutes, or until eggs are set in the center and don’t jiggle.

Tips and Variations for the Best Breakfast Casserole

What I love about this casserole is how versatile it is! You can easily mix and match ingredients. Here are a few tips to make it your own or simplify prep.

• Cooking Spray: Always spray your baking dish to prevent the eggs from sticking.
• Overnight Prep: Make the casserole the night before, cover, and refrigerate. Just bake it the next morning—perfect for busy mornings or holiday breakfasts.
• Baking Tip: It usually takes 50-60 minutes in my oven. If the edges brown too fast, cover them with foil or lower the oven temperature and bake longer.
• Potatoes: I use frozen hash browns, but you can use fresh potatoes, thinly sliced, or even a Potatoes O’Brien mix.
• Veggies: I love red bell pepper and onion, but any veggies work—broccoli, zucchini, spinach, or mushrooms. Try swapping the cheese for mozzarella or pepper jack if using spinach.
• Meat: Maple sausage is my favorite, but bacon, ham, chorizo, or a vegetarian version work great too.
• Slow Cooker: Short on time? Make it in a slow cooker! Just add everything the night before and wake up to a fully-cooked breakfast. Try our Slow Cooker Breakfast Casserole.

Feeding a Crowd

When I have guests over, this is my go-to breakfast casserole. It’s so simple to put together, and you can easily adjust it to suit even the pickiest eaters. This recipe makes 12 large servings or 15 regular servings, but I have a trick—since I can fit two 9×13 pans in my oven, I double the recipe and can feed up to 30 people! I just switch the pans halfway through (top and bottom) for even cooking. I also like to pre-cut slices in the pan, so everyone gets a piece.

What to Serve with this Breakfast Casserole Recipe

At home on a regular morning, we usually just eat it as is, or I’ll serve it with some fresh fruit on the side. My kids love to add ketchup on top, while my husband and I like to top ours with sour cream and salsa. But if I’m feeding a bigger or especially hungry crowd, I’ll add something sweet to balance out the meal.

• Fresh Fruit: Strawberries, melon, or citrus fruits are a great way to balance out the richness.
  • Fruit Trifle
  • Cream Cheese Fruit Dip
  • Fruit Salsa
  • Easy Fruit Salad
• Smoothies: A fruit smoothie is a great way to add some fiber and vitamins to your breakfast!
  • Boba Smoothies
  • Piña Colada Smoothie
  • Creamy Peach Smoothie
  • Mango Avocado Smoothie
  • Banana Berry Smoothie

Storing and Making Ahead Easy Breakfast Casserole

Here’s another great tip: Turn this into a make-ahead breakfast casserole! You can prepare it the day before and keep it in the fridge, or even freeze it for later. If you have any leftovers, just store them in an airtight container in the fridge, and they heat up perfectly in the microwave.

Prep the Day Before

To save time in the morning, you can prep the casserole the day before you plan to bake it. Just follow the first few steps in the recipe, cover the dish with plastic wrap, and pop it in the fridge. When you’re ready to bake, take it out about 30 minutes before you put it in the oven, then bake for an hour or until a toothpick or knife inserted in the center comes out clean.

Freezing Instructions

If you want to freeze it, just follow the recipe up until the casserole is done, then let it cool. After it’s cooled, wrap it tightly with plastic wrap, then cover it with aluminum foil to keep it from freezer burn. You can even freeze individual portions, so you can heat up just one serving at a time. It will stay good in the freezer for up to 2 months.

When you’re ready to cook it from frozen, just thaw it in the fridge overnight, then bake at 350°F for about 30-40 minutes, or until it’s heated through. If you’re heating individual portions, just thaw and then microwave or bake until warm. It’s so comforting knowing there’s a delicious breakfast waiting in the freezer, ready to go whenever you need it!
