Can I use frozen ravioli?
Yes. Follow the package directions if you have them. If you do not, boil straight from frozen and start checking doneness about 1 to 2 minutes after the “fresh ravioli” timing. You want them tender and heated through, not burst.
Do I have to use brown butter?
You do not have to, but it is the secret weapon. For a stress-free cue, watch for the milk solids (the little specks) to turn amber and smell nutty. As soon as you see golden-brown bits, pull the pan off the heat for a few seconds so it does not tip into burned.
What mushrooms work best?
Cremini are perfect for everyday cooking. If you want to level up, use a mix of cremini and shiitake, or add a few oyster mushrooms for extra “forest” energy.
How do I keep mushrooms from getting soggy?
Do not overcrowd the pan, and do not salt them at the very start. Let them brown first, then season. Brown equals flavor. If your skillet is smaller than 12 inches or your mushrooms look very wet, brown them in two batches.
Can I make this vegetarian?
It already is, as long as your ravioli and Parmesan are vegetarian-friendly. If that matters to you, check labels for animal rennet.
Any allergy notes?
This dish typically contains gluten (ravioli), dairy (butter, cream, Parmesan), and soy (soy sauce). Swap tamari for gluten-free soy sauce, and use gluten-free ravioli if needed.
