2 large Portobello mushrooms: The star of the dish, they provide a meaty texture and rich, earthy flavor. Opt for fresh, firm mushrooms for the best results.

1 teaspoon garlic powder: Offers a burst of flavor without the hassle of fresh garlic. Fresh minced garlic can be substituted for a more intense flavor.

How to Make Portobello Mushroom Burgers

Clean the Mushrooms: Gently wipe the mushrooms with a damp paper towel to remove dirt, and remove stems.
Prepare the Marinade: In a small bowl, whisk together 2 tablespoons of olive oil, 1 tablespoon of balsamic vinegar, 1 teaspoon of garlic powder, and 1 teaspoon of dried oregano. Add a pinch of salt and pepper.
Marinate the Mushrooms: Place the cleaned mushrooms in a shallow dish and pour the marinade over them, ensuring all surfaces are covered. Let them marinate for at least 15 minutes; longer if time allows.
Preheat the Grill: Heat a grill or grill pan over medium-high heat.
Grill the Mushrooms: Once hot, place the marinated mushrooms on the grill. Grill for about 5-7 minutes on each side, or until they are tender and have nice grill marks.
Toast the Buns: While the mushrooms are grilling, cut the burger buns in half and toast them lightly on the grill or in a toaster.
Assemble Your Burgers: Place the grilled Portobello mushrooms on the bottom half of each bun. Top with your choice of fresh spinach, slices of tomato, avocado, or cheese. Cap with the top half of the bun.

Storing & Reheating

For storing leftovers, keep the cooked Portobello mushroom burgers in an airtight container in the refrigerator for up to 3 days. If you wish to keep them longer, they can be frozen for up to 3 months. To reheat, thaw them in the refrigerator overnight and then warm them in a skillet over low heat for about 5-7 minutes. Note that the texture might change slightly after freezing, so refresh with a drizzle of olive oil before serving.

Try adding your favorite condiments like mustard or aioli to bring an extra flavor dimension.
If using cheese, consider a slice of provolone or mozzarella for that melty goodness.
Planning ahead? Marinade the mushrooms in advance to let flavors deepen.
