Expert Notes for the Best Results

• Skip the Soggy Struggle: To dodge watery layers, fully sauté the mushrooms until they’re deeply golden and any liquid cooks off. Wilt the spinach just enough so it’s still bright but not wet excess moisture is your lasagna’s nemesis.
• Cheese That Goldens Just Right: For a melt that’s oozy on the inside and lightly crisped on top, use a mix of mozzarella and a sprinkle of Parmesan. Uncover the lasagna for the last stretch so those edges can bubble up bronzed and irresistible.
• Sauce Savvy: Your béchamel should coat the back of a spoon and pour like a velvet ribbon. If it’s runny, simmer another minute or two; if too thick, whisk in a splash more milk.
