Cooking with Mushrooms: Roasted Portobello Mushroom Caps

Have you noticed all the buzz about mushrooms lately, too? From Star Trek: Discovery’s spore drive to learning that oyster mushrooms can eat plastic, we understand why some might refer to 2022 as the year of the mushroom.

As avid RVers, we love foraging and cooking with mushrooms while on the road. If you’re new to RVing and foraging for wild food, start by looking for mushrooms like lion’s mane, chicken of the woods, hedgehog, giant puffballs, and hen of the woods. Many resources are, but I recommend investing in a field guide. Forage ethically and know what you’re picking, as mushrooms can be toxic. When in doubt, throw it out.

Benefits of Mushrooms

Did you know mushrooms are low in calories and sodium and have no cholesterol? One cup of raw mushrooms contains 16 calories and one to two grams of protein. They’re also a good source of selenium, potassium, riboflavin, and niacin. These are just some of the reasons we love cooking with mushrooms!

Cooking with Mushrooms

Once you forage, it’s time to cook your mushrooms! Here’s a roasted portobello mushroom cap recipe you can make wherever you happen to be – on the road or at home. The mushrooms can be served on their own, topped with grated cheese, or in a hamburger bun with all the fixings.

Tip: We like to keep the discarded stems to use in a soup or stir fry another day!
