Cook ground beef and minced garlic clove for 5-7 minutes until browned.
1 lb ground beef, 1 garlic clove, 1 pinch salt
Add the beef broth, water, and pasta. Bring everything to a rolling boil and cook until the pasta according to package instructions, about 10 minutes.
2 cups beef broth, 8 oz penne, 3/4 cup water
5 minutes into boiling the pasta, add the broccoli florets and frozen peas. Bring the sauce back up to a low simmer and cook everything until the vegetables are tender and the pasta is al dente. Add more broth if needed (note 1 below).
1 1/2 cups broccoli florets, 1 cup frozen peas
On a low simmer, add the cream, followed by parmesan cheese. Stir until the cheese has fully melted and the sauce is creamy. Season to taste (note 2 below).
1 cup heavy cream, 1 cup parmesan cheese, 1/4 pinch salt, 1/8 tsp ground black pepper
Serve immediately with chopped parsley.
1/4 cup parsley

Notes
Adjust consistency: If the sauce gets too dry while you're cooking the pasta, add more beef stock but you don't want too much liquid or the sauce will be too runny. For a thicker sauce later on, add 2 tsp of cornflour mixed 1/4 cup of extra beef stock.Seasoning: Taste and adjust the seasoning of the sauce at the end as the broth and parmesan cheese can both add a lot of saltiness.Storage: You can store the dish in an airtight container in the fridge for up to 3 days. Slowly reheat the pasta dish on the stove or in the microwave. Add more stock to the homemade Alfredo sauce if it's too dry. I don't recommend freezing leftovers of this dish as the texture of the creamy meat sauce and broccoli will change.
