FAQ
Can I use other types of mushrooms?
Yes, shiitake, portobello, or even white button mushrooms work well. Adjust cooking time slightly based on mushroom size and density.
How long will these keep in the refrigerator?
Store covered for up to 3 days. The flavor actually improves overnight as the mushrooms absorb more of the balsamic glaze.
Can I make this ahead for meal prep?
Absolutely. Make the full recipe and reheat gently in a skillet or microwave. They're great for adding to grain bowls or pasta.
