My grandma always tossed a pinch of nutmeg in the white sauce. It’s such a tiny thing, but wow does it make a difference at the table.
Easy Prep Ahead
You can put the whole thing together a day early and stash it in the fridge covered. Just let it warm up on the counter before it hits the oven.
Cheese Choices
For the best taste and melt, combine shredded mozzarella, creamy ricotta, and a handful of aged Parmesan cheese.
Veggie Steps
Mushrooms need room to brown, so don’t crowd them in the pan or they’ll just steam instead of getting flavorful and golden.
Sauce Tricks
Keep that béchamel lump-free by slowly pouring in warmed milk and whisking all the way.
