Mushrooms can be a bit bland on their own, so the key to adding flavor to this portobello mushroom recipe is our Smoked Tea Rub! Added to a marinade, this rub brings a balance of sweetness and smokiness with notes of rosemary and the added crunch of sesame seeds.

These burgers are naturally vegan and vegetarian. For a gluten-free burger be sure to choose a gluten-free burger bun.

Portobello Mushrooms.

What are Portobello mushrooms? And why use it as a burger substitute?

First off, just how do you spell portobello mushrooms? We’ve seen them spelled as portabella, portobello, and portobella in reputable sources. Go with what works for you! For clarity, we’re sticking with Portobello!

Now that we know how to spell the word, just what are portobellos? Portobello mushrooms are mature white, button, or crimini mushrooms. All three of these mushrooms are a type of Agaricus bisporus strain of fungus, so all three of the mature versions of these mushrooms are portobello mushrooms.

Portobello mushrooms are known for their meaty texture and savory almost meat-like flavors.

Balsamic Vinegar. Balsamic vinegar adds a sweet and deep note to this recipe. Although SpiceTopia offers many different infused balsamics, we find that traditional balsamic without any extra flavors works best in this recipe.

Lemon Juice. This recipe calls for 1 tablespoon of lemon juice which is the juice of about one lemon.

Extra Virgin Olive Oil. We enjoy the peppery sharp flavor of Arbequina Olive Oil in this recipe.

Parsley. If you have fresh flat-leaf parsley available, chop ¼ cup roughly–stems and all. If fresh is not available, 2 tablespoons of Dried Parsley works well.

Smoked Tea Rub. Our Smoked Tea Rub has a base of Lapsang Souchong Tea which is a tea smoked over pine needles. This unique tea brings a note of smokiness to the rub. In addition to the smoked tea, we add granulated molasses, paprika, garlic, fennel, rosemary, and marjoram to this rub. All these flavors together add notes of smokiness, rich sweetness, and herbiness to this marinade.


How to Prepare a Portobello Mushroom to Eat

Be sure to look for medium-sized mushrooms which will fit well on your bun.

All of the portobello mushroom is edible, but the stem and gills are best removed. Stems can be woody and are hard to eat. They easily snap off and can be saved to add to any stock recipe. The gills, while edible, can seep out a dark murky liquid making your food around it an undesirable brownish-gray color! So, it’s best to remove them with a spoon.

After removing the stem and gills, wipe the mushroom down with a barely damp towel.

Portobello mushrooms tend to shrink when cooked. We find when cooking them whole, that scoring the cap (or top of the mushroom) allows steam to escape which allows the mushroom to cook more quickly and evenly and prevents some of that shrinkage.

If it’s not grilling season where you are, Portobello Mushrooms also turn out well roasted. Roast on a rack at 450°F for 15 minutes.

Let’s get cooking!
