Nothing beats the smell of warm and earthy mushroom caps stuffed with hatch chiles from the oven. Often called umami (fifth taste) mushrooms have a rich-tasty profile that can be added to stocks, soups, and sauces. The Early Greeks and Romans are thought to be the first cultivators of mushrooms, using them in their cuisines. Today you may find thousands of varieties of  this desirable fungus. What you see today in the markets are the cultivated types. For the more exotic ones reach for the wild mushrooms such as chantrelle, enoki, morel. shitake. In this recipe I’m used the common baby bella mushroom .

As for Hatch chiles, they can be found growing in the New Mexico region for a very short time during the summer months. Because of the unique weather conditions the chiles develop a very unique flavor. Hatch Chiles have a meaty flesh and mild-medium heat making them ideal for use in Chile Con Queso, Chile Rellenos, and Chile Verde. But, don’t stop there…try roasting and using them in salads, soups, stews, dips, and sandwiches.  Go to Melissa’s Produce for more information about these special chiles.

Mushrooms are a great replacement for meat.  Exploring with all the varieties will help you add more flavor and texture to your dishes. Mushrooms are a fungus not a real vegetable. Often, the deeper the mushrooms’ color, the more umami it brings to the table. They contain a variety of powerful phytochemicals and have been linked to decreased risk of chronic diseases, especially cancer.

The more mushroom umami you add to a dish, the more intense flavor it imparts. Here are a few suggestions~

  • beans, seasoned with herbs and lemon juice
  • stock and sauces for more flavor
  • add to vegetable based soups
  • scrambled eggs
  • stews with root vegetables
  • spinach salad
  • risotto or rice dishes
  • pasta sauces and pasta

Try this delicious appetizer and share with your family and friends!
