Portobello burgers with grilled onions, salsa and mozzarella

Portobello burgers with grilled onions, salsa and mozzarella

I love to serve these juicy, spicy burgers with fresh corn, grilled in their husks, and tender baby greens from our local Farmers’ Market or from my garden.

Food & wine pairing: Syrah or Zinfandel with Portobello burgers

Red wine icon
There are many wines you could serve with these burgers: Cabernet Sauvignon, Malbec, Tempranillo or even Pinot Noir. But for a bit of fun you might want to try a red with a hint of spice, like a Syrah or Zinfandel.

In-Their-Husks Grilled Corn on the Cob

Portobello burgers with grilled onions, salsa and mozzarella

serves 4
active time: 40 min

For the onions

  1. 2 medium red onions – peeled and cut crosswise in 1/4″ slices
  2. 1 tablespoon aged balsamic vinegar
  3. 1 tablespoon extra virgin olive oil
  4. 1/8 teaspoon sea salt
  5. freshly ground black pepper to taste

For the Portobello

  1. 4 medium Portobello mushrooms (about 4″ across, approximately the same size as the buns) – stems trimmed at base of cap, left whole and brushed clean
  2. extra virgin olive oil to brush the vegetables
  3. sea salt to taste
  4. freshly ground black pepper
  5. 4 oz (115 g) fresh mozzarella – cut in 1/4″ slices (slices should be same size as the Portobello mushrooms)
  1. 4 whole-wheat buns
  2. olive oil to brush the buns
  3. 1 jar roasted garlic salsa
  4. 1 recipe in-their-husks grilled corn on the cob
  5. 1 recipe leafy green salad with aged balsamic vinaigrette

  1. Step 1: For the onions – Place the onion slices in a large bowl. Add the vinegar, oil, salt and pepper and toss with your fingers until well blended. Set aside.
  2. Step 2: For the mushrooms – Brush the mushrooms lightly with olive oil, on all sides. Sprinkle with salt and pepper. Place on a jelly roll pan and set aside.
  3. Step 3: Preheat gas grill to medium-high heat or prepare charcoal grill. When the grill is ready place the onion slices in a perforated stainless steel pan and grill until the onions are golden-brown, tossing with tongs only occasionally. Remove from pan and transfer to a bowl. Place the mushroom (cap-side-down) on the grill. Grill until grill marks appear on each side, flipping them two or three time during the cooking so they grill evenly. When the mushrooms are almost done, turn the mushrooms gill-side-up and top with a slice of mozzarella. Continue grilling until the mozzarella starts to melt. Transfer to a platter and sprinkle with a little salt and pepper to taste.
  4. Step 4: Place the buns on the grill cut-side-down and grill until grill marks appear. If your grill is very hot it could take only a few seconds.
  5. Step 5: To assemble the burgers, brush the buns on both sides with a little olive oil. Top the bottom bun with a few red onion slices, one Portobello mushroom and some salsa. Finish with the top-side of the bun and slightly press with your hand. Serve immediately while still warm, with in-their-husks grilled corn on the cob and a leafy green salad with aged balsamic vinaigrette.

  3. I think I was one of your “testers” for this one. They were superb then, although I did have to enjoy a third serving to be sure!

    • Tim! You have an excellent memory. You were indeed a tester for this recipe (I’m glad you enjoyed it enough to remember it!)… Which makes me think, that if you’re willing, I have loads more for you to test 😉

  5. Gosh, send that rain my way! We are SO dry. While you’re at it, you can send me some of these amazing meatless burgers. I love the mushroom, salsa and gooey cheese combination 🙂

  6. Hot stuff! Obviously, we don’t have the 4th of July in Cayman but tomorrow is a bank holiday called Constitution Day! We were thinking of grilling the standards but (if the supermarkets are open!) I’m thinking this mega burger would be a much sexier alternative 🙂 Looks fab!
