This Simple Mushroom Burger is SO FLAVORFUL and TASTY! Grill it or cook it on the stovetop. 

These Mushroom Burgers are so meaty and filling that even meat lovers will enjoy them. The Portobello mushrooms are marinated in a garlic-balsamic marinade, and they just soak up the flavors. These would taste best when cooked on the grill (like any food, right?), but it is also possible to cook these mushroom burgers on the stovetop.

By the way, Portobello mushrooms (or other edible mushrooms) are good for you. They are low in fat, high in fiber, and contain B vitamins, selenium, and potassium.  When buying Portobello mushrooms, look for smooth, firm caps without wet slimy patches. Store them in the refrigerator, inside a loosely closed bag or wrap them in a damp cloth. Let’s get back to cooking!

INGREDIENTS FOR THE MUSHROOM BURGER:

For the marinade:

• 3 tbsp. olive oil
• 2 tbsp. balsamic vinegar
• 2 garlic cloves, minced
• 1 tsp. dried Italian herbs
• salt and pepper, to taste

For the burger:

• 2 hamburger buns
• 2 caps Portobello mushroom
• 2 tsp. mustard
• 2 slices provolone, or your favorite cheese
• 1 small onion, cut into rings and fried

INSTRUCTIONS: 

1. Mix all of the marinade ingredients together. Cover the mushrooms with marinade on both sides. (For best results, marinate the mushrooms for at least 2 hours.)
2. IF USING AN OUTDOOR GRILL: Brush grate with oil. Grill the mushrooms for 5-7 minutes on each side. Use the leftover marinade for basting.
3. IF USING A STOVETOP: Cook mushrooms in a frying pan covered with a tight lid, on medium-low heat, for about 4-5 minutes on each side. Cooking time may vary depending on the size of the mushroom. If your mushrooms are small, they will need 3 minutes on each side.
4. While the mushrooms are cooking, toast the buns. You may choose to skip this step.
5. Spread 1 tsp. of mustard on each bun.
6. Once the mushrooms are cooked, lift the lid, place the cheese on top, and return the lid, allowing the cheese to melt.
7. Transfer the mushrooms to the buns, top with fried onions and assemble the burger.
