The Best Sausage Casserole

If breakfast is your favorite meal of the day, you will love this sausage casserole. From the seasoned sausage to the hearty hash browns, this casserole recipe is perfect from the first bite to the last.

Not to mention, this casserole works equally as well for breakfast as it does for dinner. You can even assemble it at night and toss it in the oven right before breakfast the next morning.

But, even if you make it in the morning, it will only take you about 10 minutes of prep work to whip up. Then, the oven does all the heavy lifting after that.

In addition to tasting great, though, this sausage casserole is also a super customizable recipe. With that said, I'll get into more ways you can change it up later on.

By the way, if you're making this for brunch (which you totally should), then I highly recommend serving it up alongside this Starbucks cafe mocha recipe. After all, you'll have plenty of time to make it while your casserole is in the oven.

Ingredients

As I mentioned above, the ingredient list is pretty straightforward, and you have tons of room to modify things depending on the flavor you're after. Honestly, one quick trip to the grocery store is all you need to make this easy sausage and potato casserole!

Anyway, here's exactly what you'll need to make this sausage casserole:

• ½ lb. breakfast sausage (I used spicy sausage)
• ¼ cup chopped red bell pepper
• ¼ cup chopped yellow bell pepper
• ¼ cup chopped onions
• Salt and pepper, to taste
• 10oz. hashbrowns, fresh or frozen, chopped
• 6 eggs
• ¼ cup heavy cream
• ¼ cup milk
• 1 ¼ cups shredded cheddar cheese
• Fresh parsley, chopped, for garnish

See, that's not so bad, right?

By the way, if you have all - or most - of these ingredients, then you already have everything you need to make this chicken hashbrown casserole as well.

Ingredient Substitutions and Suggestions

As I mentioned earlier, there are a ton of different ways you can change up this casserole. 

For example, I used some spicy breakfast sausage to make my casserole because that's what my family likes, but you could easily make it with Italian sausage, chicken sausage, or vegetarian sausage!

As for the veggies, I love the combination of peppers and onions, but you can leave one or both of them out if you don't like them. You can also add or replace them with other veggies like broccoli, kale, and spinach. 

Lastly, for the optional toppings, I like to serve this breakfast sausage casserole with some sour cream to counter some of the heat. Having said that, you can also serve it with sliced avocado on top, salsa, or even this McDonald's breakfast sauce! 

How To Make Sausage Casserole

Now it's time for the fun part, making the breakfast casserole!

Honestly, making this casserole could not be any easier. As I said, it will only take you 10 minutes to prepare the casserole, then it just has to bake in the oven.

So let's stop wasting time and get into how to make sausage casserole.

Step 1: Cook The Sausage & Veggies

First things first, preheat the oven to 375°F (190°C) and grease an 8x8 inch. baking dish with cooking spray or butter.

While the oven is preheating, you can cook the sausage. To do this, heat a large skillet over medium-high heat and add enough oil to fully coat the bottom of the pan.

Then once your pan is hot, remove the sausage casing and add the sausages to the pan. Now cook the sausages for a few minutes, breaking them apart into crumbles until they're golden brown.

Next, add the bell peppers and onions to the pan with the sausage and cook them for 5 minutes, making sure to stir frequently. 

Once the veggies are cooked, you can transfer the sausage, peppers, and onions to the prepared baking dish.

Step 2: Make the Egg Mixture

Now that the sausage and veggies are prepared, you can make the egg mixture.

To do that, beat add the eggs, milk, and heavy cream to a large bowl and beat them together with a whisk until everything combines.

Then add the shredded sharp cheddar cheese to the bowl along with a dash of salt and pepper, and give the mixture a good stir.

Now you can pour the egg mixture into the casserole dish over the sausage and veggies. Lastly, add the hash browns on top and gently stir to combine all of the ingredients together.

Step 3: Bake The Casserole

Now it's time to bake the casserole! Put this breakfast casserole in the oven for 45 minutes or until the top is golden brown and the egg mixture has solidified.

By the way, you can test and see if the egg is fully cooked by gently pressing down on the center of the casserole. If liquid comes through, let it cook for a few more minutes.

Finally, let the cooked casserole cool on a wire rack briefly before slicing. Then slice the sausage casserole and serve with anything that you want. Enjoy!

How To Store Sausage Casserole

This recipe for sausage casserole will make 4 hearty servings. So it's really perfect for a big family breakfast or dinner or to have leftovers as meal prep for the week.

Speaking of leftovers, if you end up with some, you can either put a lid on the casserole dish or transfer the leftover breakfast casserole to an airtight container. Stored this way, it'll last in the fridge for up to 4 days. 

Alternatively, if you want to make it ahead of time and have it on hand for longer, you can freeze the casserole for up to 6 months.

How To Reheat Sausage Casserole

Now, this sausage casserole is actually really tasty cold, but you can definitely heat it up.

To reheat your sausage casserole, put it back in a casserole dish, if it's not still in it, and warm it in the oven at 350°F for about 10-12 minutes or until it reaches your desired temperature. 

For reheating the frozen casserole, simply cover the baking dish with aluminum foil and heat at 350°F in the oven until it's warmed through.

Wrapping It Up

That's how to make sausage casserole! I know I'm biased, but out of all the sausage casserole recipes out there, I think this is the best one.
