Quick, easy broccoli and cheese sauce recipe, homemade with simple ingredients in one pot in 20 minutes over stovetop. A classic side side dish with steamed broccoli and creamy cheddar cheese mixture.
In a large nonstick pot, add milk, cheese, dissolved cornstarch, salt, pepper, garlic, mustard.
Cook over low heat, whisking often, until cheese has fully melted into a thick, smooth sauce.
If sauce is too thick, thin it out by adding a little more milk. If it's too thin, cook uncovered for longer until excess liquid evaporates and sauce is reduced.
Pour this over steamed broccoli (I used roasted). Season with more salt and pepper, if you like.
Serve immediately and enjoy!
