Paula Deen’s Portobello Mushroom Burger: A Savory Delight

I remember one summer cookout in Savannah, the air thick with humidity and the smell of grilling meats. I was still a young apprentice, eager to impress. Everyone was raving about the burgers, but I was captivated by something else – a platter of plump, juicy portobello mushrooms sizzling on the grill. That day, I learned that sometimes, the simplest things, like a perfectly grilled mushroom, can be the most unforgettable. This recipe, reminiscent of that day, captures the earthy depth and satisfying heartiness of portobellos, transforming them into a burger that even the most ardent meat-lover will appreciate.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 8 minutes
• Total Time: 18 minutes
• Servings: 4
• Dietary Type: Vegetarian

Ingredients

• 4 portobello mushroom caps, cleaned
• 1/4 cup olive oil
• Salt & freshly ground black pepper
• 1/2 cup mayonnaise
• 1 tablespoon prepared pesto sauce
• 2 teaspoons coarse grain mustard
• 4 hamburger buns, split, buttered, and toasted
• 1 cup baby arugula
• 1 (12 ounce) jar roasted red peppers, drained

Equipment Needed

• Grill
• Small bowl
• Spatula

Instructions

1. Preheat your grill to medium-high heat. Ensure the grates are clean to prevent sticking.

2. Brush the portobello mushroom caps generously with olive oil. Season them evenly with salt and freshly ground black pepper. Don’t be shy with the seasoning, as portobellos can absorb a lot of flavor.

3. Place the mushroom caps on the preheated grill, smooth side down. Cover the grill with the lid and cook for 6 to 8 minutes, or until the mushrooms are tender. The cooking time may vary slightly depending on the size of your mushrooms and the heat of your grill. You’ll know they’re ready when they are slightly softened and have grill marks.

4. While the mushrooms are grilling, prepare the sauce. In a small bowl, combine the mayonnaise, pesto, mustard, 1/4 teaspoon salt, and 1/4 teaspoon pepper. Mix well until all ingredients are fully incorporated. This sauce adds a tangy, herbaceous kick that complements the earthy mushrooms beautifully.

5. Spread the mayonnaise mixture evenly over the cut sides of the buttered and toasted hamburger buns. The toasting helps prevent the buns from becoming soggy.

6. Divide the baby arugula evenly over the bottom halves of the buns. Arugula adds a peppery bite and a fresh, vibrant green color.

7. Top each bun with the drained roasted red peppers, distributing them evenly. The sweetness of the roasted red peppers adds another layer of flavor.

8. Once the mushrooms are grilled and tender, place the mushroom caps over the roasted red peppers.

9. Cover with the tops of the buns and serve immediately.

Expert Tips & Tricks

• Marinating the Mushrooms: For even more flavor, marinate the portobello caps in the olive oil, salt, and pepper for at least 30 minutes before grilling. You can add other herbs and spices to the marinade, such as garlic powder, onion powder, or dried oregano.
• Preventing Soggy Buns: Toasting the buns is essential. You can also lightly grill the cut sides for extra flavor and crispness.
• Grilling Without a Grill: If you don’t have a grill, you can cook the portobello mushrooms in a grill pan on the stovetop or broil them in the oven. If broiling, keep a close eye on them to prevent burning.
• Adding Cheese: A slice of melted provolone, mozzarella, or even a tangy goat cheese would be a delicious addition to this burger. Add the cheese during the last minute or two of grilling to allow it to melt.
• Making it Vegan: Use vegan mayonnaise and ensure your pesto is dairy-free (some pestos contain Parmesan cheese).

Serving & Storage Suggestions

Serve these portobello mushroom burgers hot off the grill. They pair perfectly with a side of sweet potato fries, a fresh green salad, or grilled corn on the cob.

Leftovers can be stored in the refrigerator for up to 2 days. Store the mushrooms and the bun components separately to prevent the buns from becoming soggy. Reheat the mushrooms in a skillet or microwave before assembling the burger. The assembled burger is best eaten immediately. Do not freeze.
