Instructions
6 steps · tick them off as you cookWhisk balsamic vinegar, olive oil, garlic and thyme; marinate portobello caps gill-side-up for 20 minutes.
20 minutesHeat a grill pan to medium-high. Grill caps 4-5 minutes per side until tender and lightly charred.
4-5 minutesIn the last minute, top each cap with provolone and cover to melt.
Toast the buns cut-side-down until golden.
Spread mayo on the buns and layer arugula and roasted red pepper.
Set the cheesy portobello on top, cap the burger and serve warm.
Chef's tip
Score the gills lightly and grill the cap dome-side-down first — it releases excess moisture so the mushroom stays meaty, not soggy.
Suggested pairing
A medium-bodied Pinot Noir complements the earthy grilled mushroom and balsamic.
