🧾 Ingredients
- Potatoes - Use Yukon Gold, waxy potatoes, or any potato that holds its shape well when baked.
- Broccoli - Fresh broccoli florets work best, but frozen broccoli is a good shortcut (just thaw and pat dry).
- Shredded Cheese - Sharp cheddar adds great flavor, but you can also use mozzarella, Gruyère, or a mix.
- Milk - To create a creamy, velvety white sauce. Check this guide for more details on Besciamella (How to make Béchamel Sauce or White Sauce).
- Butter & Flour - Used to make a simple roux that thickens the cheese sauce.
- Salt & Pepper - Essential seasoning for both the vegetables and the sauce.
- Seasoning - A pinch of garlic powder, onion powder, and nutmeg will add more flavor to the vegetables and cheese sauce.
