Portobello Mushroom Burger Recipe

This Simple Portobello 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.

Should you Remove Gills from Portobello Mushrooms

A lot of you wonder why I removed the gills from portobellos. While the gills are edible, I choose to remove them, because they add a bit of muddy flavor. However, it is perfectly ok to leave them, if you prefer. Here is a video from America's Test Kitchen you might find interesting: How to Properly Prepare Portobello Mushrooms

How to Make Portobello Mushroom Burger:

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.

Are these Mushroom Burgers Healthy?

Depends on how you serve them. The "burger" itself is just a marinated mushroom. It is Whole30 compliant, low carb, keto-friendly, vegan, gluten-free, and dairy-free. It’s suitable for pretty much every eating style out there. Serve the "burger" on whole wheat bun, together with fresh veggies and some mustard for the most health benefits.

How to Serve Mushroom Burgers

Choose your bun. Use the bun you enjoy most: potato bun, ciabatta bun, kaiser roll, pretzel roll, keto hamburger bun, or English muffin.

Choose your sauce. Mayonnaise, mustard, ketchup, BBQ sauce, blue cheese, or ranch dressing are among my favorites.

Choose your toppings. Get creative! Popular options are: lettuce, tomatoes, onions, avocado, bacon, spinach, arugula, caramelized onions, grilled peppers, grilled eggplant, and pickles.

Choose your cheese. Fresh mozzarella, Swiss, provolone, Monterey Jack, feta, goat cheese, or cheddar are popular options.
