Portabella and Gouda Burger with Garlic Mayo

I still remember the first time I tasted a portabella mushroom burger that truly blew me away. It wasn’t at some fancy restaurant, but a humble outdoor market, where the aroma of grilled garlic mingled with the earthy scent of the mushrooms themselves. The vendor had stacked layers of perfectly grilled portabella, melted cheese, and fresh tomato between crusty bread. That simple creation ignited my love for this hearty, satisfying vegetarian alternative, and this recipe aims to recapture that moment of pure culinary joy.

Recipe Overview

• Prep Time: 45 minutes
• Cook Time: 10 minutes
• Total Time: 55 minutes
• Servings: 2
• Dietary Type: Vegetarian

Ingredients

• 2 large portabella mushroom caps, cleaned and stem removed
• 3-4 slices gouda cheese (thin slices, smoked is good!)
• 2 tablespoons olive oil
• 1 clove garlic, sliced
• 1 teaspoon dried thyme
• 2 slices fresh ripe tomatoes (thick slices)
• 2 good bakery rolls or 4 slices French bread, lightly toasted

Garlic Mayo

• 2 tablespoons mayonnaise
• 1 teaspoon lemon juice
• 1 clove garlic, minced
• 2 teaspoons Bermuda onions, minced
• ½ teaspoon dried thyme or 1 teaspoon fresh thyme, minced
• ½ tablespoon dried parsley or 1 ½ tablespoons fresh parsley, minced

Equipment Needed

• Zipper-lock bag
• Skillet with lid
• Small bowl
• Fork or whisk

Instructions

1. In a zipper-lock bag, combine 2 tablespoons of olive oil, the sliced clove of garlic, and the dried thyme.
2. Add the cleaned portabella mushroom caps to the bag. Seal the bag, pressing out any excess air. Gently massage the marinade into the mushrooms to ensure they are well coated.
3. Marinate the mushrooms in the refrigerator for at least 30 to 45 minutes. This allows the flavors to penetrate the mushrooms, resulting in a more flavorful and juicy burger.
4. While the mushrooms are marinating, prepare the Garlic Mayo. In a small bowl, combine the mayonnaise, lemon juice, minced clove of garlic, minced Bermuda onions, ½ teaspoon of dried thyme (or 1 teaspoon of fresh thyme), and ½ tablespoon of dried parsley (or 1 ½ tablespoons of fresh parsley).
5. Stir the Garlic Mayo ingredients together thoroughly with a fork or whisk. Cover the bowl and refrigerate the Garlic Mayo to allow the flavors to meld while the mushrooms marinate.
6. When the mushrooms are ready, heat a little olive oil (about a tablespoon) in a skillet over medium heat.
7. Carefully place the marinated portabella mushroom caps in the skillet, stem side down. Try to include as much of the sliced garlic and thyme from the marinade as possible in the skillet to infuse the oil and further flavor the mushrooms.
8. Sauté the mushrooms for about 5 minutes, allowing them to brown and soften on the first side.
9. Turn the mushroom caps over and immediately top each with 3-4 slices of gouda cheese.
10. Cover the skillet with a lid. This will trap the heat and help the cheese melt quickly and evenly.
11. Cook for another 5 minutes, or until the gouda cheese is completely melted and bubbly. Keep a close eye on the mushrooms during this step, as the cheese can melt very quickly and you want to prevent it from burning.
12. Alternatively, these are also delicious grilled. Prepare your grill to medium heat and grill the marinated mushrooms for about 5 minutes per side, topping with gouda during the last few minutes until melted.
13. To assemble the burgers, spread the prepared Garlic Mayo generously on the toasted bakery rolls or French bread.
14. Place a cooked portabella mushroom cap on the bottom half of each roll or slice of bread.
15. Top with slices of fresh, ripe tomatoes.
16. Finish with the top half of the roll or bread, and serve immediately. Consider serving with a side of sliced avocado for added richness and flavor.

Expert Tips & Tricks

• Marinating Time: While the recipe suggests a minimum of 30-45 minutes for marinating, allowing the mushrooms to marinate for longer (even overnight) will result in a more intensely flavored burger.
• Cheese Variations: Feel free to experiment with different types of cheese. Smoked provolone, Monterey Jack, or even a sharp cheddar would all be delicious alternatives to gouda.
• Garlic Mayo Customization: Adjust the amount of garlic in the mayo to your liking. For a milder flavor, use roasted garlic instead of raw. You can also add a pinch of red pepper flakes for a touch of heat.
• Preventing Soggy Buns: To prevent the buns from becoming soggy, lightly toast them before assembling the burgers. You can also spread a thin layer of mayonnaise or butter on the cut sides of the buns to create a moisture barrier.
• Mushroom Doneness: Portabella mushrooms are done when they are tender and slightly shrunken. Avoid overcooking, as they can become rubbery.

Serving & Storage Suggestions

Serve the Portabella and Gouda Burgers immediately after assembling to enjoy them at their best. The warm, melted cheese and juicy mushrooms are most appealing fresh off the skillet or grill.

Leftover cooked portabella mushrooms can be stored in an airtight container in the refrigerator for up to 3 days. The Garlic Mayo should also be stored in the refrigerator and is best consumed within 2-3 days.

To reheat the mushrooms, you can sauté them in a skillet over medium heat or microwave them until warmed through. Reheating may slightly alter the texture, but the flavor will remain delicious.

Assembled burgers are best eaten fresh, but if necessary, they can be wrapped tightly and refrigerated for a short period (no more than 24 hours). However, be aware that the bread may become soggy during storage.
