Fill a pasta pot with water and bring it to a boil. Once it boils, salt the water well and add the broccoli. Cook for 3-4 minutes, until it turns a vivid green.

Meanwhile, heat the olive oil in a large pan or skillet over medium-high heat. Remove the chicken sausage from its casing and brown in the pan, using a spatula to break it up into crumbles. Once it is brown, use a slotted spoon and transfer the cooked pasta onto a paper towel-lined plate.

Tumble the cooked broccoli into the pan that had once held the sausage and reduce the heat to medium. Bring the water in the pasta pot back to a boil and add the pasta.

Add the garlic to the broccoli, along with the ricotta cheese and the drained sausage. Stir to combine.

When the pasta is finished cooking, drain it and pour it into the pan with the other ingredients. Stir to combine and add 1/2 cup of grated parmesan cheese, along with 1/2 cup of pasta cooking water.

Season with salt and pepper, and add more pasta water, if it is too thick.

Top with the remaining parmesan cheese. Slide the pan under the broiler to brown the top.
