Ground Beef Alfredo with Broccoli

Fill large pot with 4 to 6 cups water. Place pot on stove over high heat and bring water to rolling boil. When water begins to boil, add salt and stir to incorporate salt into water.
Once salted water begins to boil, add uncooked noodles. Cook pasta according to package instructions. When pasta is fully cooked, use tongs or slotted spoon to transfer noodles from water to bowl. Set pot of pasta water aside.
Heat large skillet over medium-high heat. When skillet is warm, add ground beef. Cook and crumble ground beef until meat is almost completely browned, with little if any pink remaining.
Add onions to skillet with ground beef. Stir to incorporate and cook 2 to 3 minutes or until ground beef is cooked through and onions are translucent.
Add garlic to skillet and stir. Sauté garlic 1 minute or until fragrant.
Add alfredo sauce and ⅓ cup reserved pasta water to skillet. Stir well to fully incorporate ingredients.
If using broccoli florets, add veggies to skillet and stir to coat broccoli in alfredo sauce.
Cover skillet with lid and reduce heat to medium-low. Simmer 5 to 8 minutes or until sauce has thickened slightly. If using broccoli, florets should be cooked through but not mushy. Note: if sauce is too thick, stir in ½ to 1 tablespoon water until desired consistency is achieved.
When satisfied with sauce, turn off heat under skillet. Add pasta and grated parmesan to sauce and mix until pasta is fully coated.
Divide pasta into preferred portions and serve warm.
