Tips & Tricks for Portobello Mushroom Steak
Baking Time
Depending on the size of your mushrooms, the bake time will vary. Make sure you use the baking time in the recipe as a guide. You will need to check on your mushrooms to make sure they are cooked to your preference.
Cooking Vegetables
I added asparagus to my baking dish as an extra side, but adding asparagus to the pan is optional. Alternately, you could add other different vegetables into your baking dish. Broccoli, snap peas, Brussels sprouts, and more would all be tasty.
Mushroom Marinade
Once you baste the mushrooms, pour the remainder of the marinade into the baking dish. As the mushrooms bake, they will soak up the additional marinade flavor. The extra marinade also provides a nice texture to the outside of the baked mushrooms.
Variations To Portobello Mushroom Steak
Seasoning the Steaks
I used a simple marinade, but you are welcome to change it up using ingredients you prefer. I find this marinade to have a savory and tangy flavoring that makes these steaks really stand out. If you are looking for a different flavor profile, feel free to alter the ingredients to match your flavor preference.
Adding Vegetables
Cook your mushrooms with different vegetables. Broccoli, cauliflower, carrots, or even green beans could be a delicious swap for the asparagus!
Portobello Mushroom Steak FAQs
How do you know when mushroom steaks are cooked?
Your steaks are done once they have browned up a bit in the oven. You will want to bake the steaks to your preference of doneness. Since there is no meat in this recipe, you can cook the mushrooms as long or little as you prefer.
How do you store leftover mushrooms?
Place your cooked mushrooms in an airtight container and store them in the fridge for 2–3 days. You will find that after 3 days the mushrooms begin to get a bit softer in texture.
How do you reheat mushroom steaks?
I find that reheating mushrooms steaks in the oven or even a skillet on the stove helps to give them a better texture. You can reheat them in the microwave, but the mushrooms will be a bit softer in texture.
