Some people swear by a meat sauce—ground beef, sausage, maybe a hint of fennel. That’s fine. But don’t just dump in raw meat; brown it first. You want flavor, not a gray, sad patch in the middle. I once saw a friend try to save time by using uncooked sausage. The lasagna looked like a crime scene from a horror movie.
If you’re going vegetarian, use mushrooms or lentils. But whatever you do, season them. A bland lasagna is a crime against humanity. It’s like wearing a stunning outfit with boring shoes—nobody remembers the shoes.
