Broccoli & Smoked Sausage Casserole

Like, was it just an overgrown hot dog? Why are you slicing it up and putting it in things? What is even happening?

So, today we’ve got this broccoli cheddar casserole situation loaded with browned smoked sausage. It’s beyond easy and oh so delicious.

You ready for the step by step?

How to make broccoli cheddar casserole with smoked sausage:

First, you’re going to want about 28 ounces of broccoli florets. I just buy the bag of florets, but you can definitely by a head of broccoli and chop it up yourself.

I don’t recommend frozen broccoli for this recipe. Fresh is best, always.

Add your broccoli to a large mixing bowl along with a couple tablespoons of water and cover it all tightly with plastic wrap. Microwave this for 2 minutes and then let it sit for 2 minutes to steam.

If you don’t have a microwave or don’t like using plastic wrap in the microwave, you can do this on a stove top steamer. You’re looking for warm, barely cooked broccoli. We’re going to finish this in the oven, so don’t over do it.

While the broccoli is doing it’s thang, slice up some smoked sausage and toss it in a hot skillet to brown. I like to get mine really browned on the edges, because it amps the flavor up majorly.

Add some cream cheese, mayo, cheddar, garlic powder, and pepper to a mixing bowl and stir really well to combine.

Dump that mixture over your hot broccoli and sausage and stir to coat. The cheese mixture is thick, but it should mix in pretty easily since the broccoli is hot.

Pop all that in a baking dish, top it off with a sprinkle of Parmesan, and bake it up!

Side dish or main dish? 

This recipe is pretty filling thanks to all of the cheese, broccoli, and sausage so you definitely could consider it a main dish. Just know that it also packs a lot of fat and is a bit carb heavy if you’re keto.

We serve this as a side dish and the nutrition is based on this making 8 servings. If you’d like to serve as a main, double each portion to serve 4 people and be sure to double the nutrition info when tracking. 🙂

What kind of smoked sausage to use? 

Smoked sausage comes in a variety of flavors and from many different brands. I was super surprised to see how many carbs are loaded in some of those sausages!

Hillshire Farm makes a smoked sausage with only 1 carb per 2 ounce serving and that’s what I use and how I’ve calculated the nutrition info for this recipe. It’s the lowest carb option I’ve seen and tastes great.
