Pro Tips

To achieve a proper sear on mushrooms without steaming, cook them in a single layer over medium-high heat. Do not overcrowd the pan; work in batches if necessary. Add onions after mushrooms have released most of their moisture, or cook them separately.
For caramelized onions, slice them uniformly and cook slowly over medium-low heat with a touch of oil and butter for 30-45 minutes. Patience is key to developing their deep sweetness and rich brown color.
Consider the onion type: yellow onions caramelize best for sweetness, red onions offer a sharper bite (good raw or lightly pickled), and shallots provide a delicate, sweet-savory profile, excellent with milder mushrooms.
Deglazing the pan after sautéing mushrooms and onions captures all the flavorful fond. Use a splash of wine, broth, or even water, scraping the bottom of the pan to incorporate these concentrated flavors into your dish.
