Heat a large skillet over medium-high heat. Add the sliced smoked cheddar sausage and cook until browned and slightly crispy around the edges.
Add the diced onion to the skillet and cook until softened and lightly browned.
Stir in the steamed broccoli florets.
Season everything with garlic salt, black pepper, garlic powder, onion powder, and Kinder’s Buttery Garlic & Herb Seasoning. Mix well so the sausage, onion, and broccoli are evenly coated.
Add both packets of Knorr Broccoli Cheddar Pasta to the skillet.
Pour in the water and milk, then add the butter. Stir everything together and bring the mixture to a boil.
Reduce the heat to a simmer and cook, stirring occasionally, until the pasta is tender and most of the liquid has been absorbed.
Add the entire bag of shredded cheddar cheese and stir until the cheese is completely melted and the pasta is creamy.
Serve hot and enjoy.
