Ingredients You’ll Need

One of my favourite things about this casserole is that the ingredients are simple and easy to find. You may already have most of them in your kitchen.

For the Casserole

• 1 bag frozen hash browns (about 20 ounces)
• 1 pound breakfast sausage
• 8 large eggs
• 2 cups shredded cheddar cheese
• 1 cup whole milk
• ½ cup heavy cream
• 1 small onion, diced
• 1 bell pepper, diced
• 1 teaspoon garlic powder
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon paprika
• Butter or cooking spray for greasing the dish

How to Make Easy Breakfast Casserole

Step 1: Prepare Your Baking Dish

Start by preheating your oven to 375°F.Grease a 9×13 inch baking dish with butter or nonstick cooking spray. I always make sure to coat the corners well because casseroles tend to stick there the most.

Step 2: Cook the Sausage

In a large skillet over medium heat, cook the breakfast sausage until it’s fully browned.As the sausage cooks, break it into smaller crumbles using a spatula. During the last few minutes of cooking, add the diced onion and bell pepper.This gives the vegetables enough time to soften while soaking up all the savory flavour from the sausage.Once everything is cooked, drain any excess grease and set the mixture aside.

Step 3: Layer the Hash Browns

Spread the frozen hash browns evenly into the prepared baking dish.I like gently pressing them down so the casserole bakes evenly and holds together nicely after slicing.The hash browns create the perfect hearty base and give the casserole that cozy breakfast texture everyone loves.

Step 4: Add the Sausage Mixture

Next, sprinkle the cooked sausage, onions, and peppers evenly over the hash browns.Try to spread everything out evenly so every slice gets plenty of flavour.

Step 5: Add the Cheese

Now comes one of the best parts the cheese.Sprinkle the shredded cheddar cheese generously across the entire casserole. I personally love using sharp cheddar because it gives the casserole a richer flavour, but mild cheddar works beautifully too.The melted cheese creates that golden, bubbly top layer that makes this casserole completely irresistible.

Step 6: Prepare the Egg Mixture

In a large mixing bowl, whisk together:

• Eggs
• Milk
• Heavy cream
• Garlic powder
• Salt
• Black pepper
• Paprika

Whisk until everything is smooth and fully combined.The heavy cream adds extra richness and helps create a softer, creamier texture that tastes absolutely amazing.

Step 7: Pour and Bake

Slowly pour the egg mixture evenly over the casserole.Once everything is combined, place the dish into the oven and bake uncovered for about 40 to 45 minutes.You’ll know it’s ready when the center is fully set and the top turns lightly golden brown.One of my favourite moments is when the casserole starts bubbling around the edges and the entire kitchen smells warm and comforting.

Tips for the Best Breakfast Casserole

After making this recipe countless times, I’ve learned a few simple tricks that really improve the final result.

1. Don’t Overbake It

The casserole should be fully set, but overbaking can make the eggs dry. I usually start checking around the 40-minute mark.

2. Use Freshly Shredded Cheese

Freshly shredded cheese melts much better than pre-packaged cheese and gives the casserole a creamier texture.

3. Let It Rest Before Serving

Allow the casserole to sit for about 10 minutes after baking. This helps it firm up slightly and makes slicing much easier.

Why This Recipe Is Perfect for Busy Mornings

Honestly, this recipe feels like a lifesaver during busy weeks.Instead of cooking breakfast from scratch every morning, you can prepare one casserole and enjoy ready to eat breakfasts for several days. It’s filling, protein packed, and much more satisfying than grabbing something quick on the way out the door.

I also love that it works for so many different situations. Whether you’re feeding kids before school, preparing brunch for guests, or simply trying to make mornings less stressful, this casserole makes everything easier.And because it reheats so well, leftovers never go to waste.

Make Ahead Instructions

One of my favourite things about this breakfast casserole is that you can completely prepare it the night before.Simply assemble the casserole, cover it tightly with foil or plastic wrap, and refrigerate overnight.

The next morning, place it directly into the oven and bake as directed.This is especially helpful during holidays or weekends when you want breakfast ready without spending extra time cooking early in the morning.

Freezing Instructions

This casserole also freezes beautifully, which makes it even more convenient for meal prep.

To Freeze Before Baking

• Assemble the casserole completely
• Wrap tightly with plastic wrap and foil
• Freeze for up to 2 months

When ready to use, thaw overnight in the refrigerator before baking.

To Freeze After Baking
