Mostly Mushroom Pasta
If you’re a mushroom-lover, this is the pasta dish for you. It’s chock-full of three kinds of fresh mushrooms (2 pounds of them) that contribute their own flavors and textures—meaty, hearty portobello; super savory, tender shiitake; and earthy, chewy cremini. We cook them in stages so the tougher mushrooms cook longer and the more delicate shiitakes cook less so they hold their shape. The touch of crème fraîche in the sauce gives the dish a stroganoff-like flavor; substitute full-fat sour cream if you can’t find it.
