Ingredients

4 large portobello mushroom caps, stems removed
1/4 cup extra-virgin olive oil
2 tbsp balsamic vinegar
2 tbsp soy sauce
2 garlic cloves, minced
1/2 tsp smoked paprika
1/4 tsp black pepper, freshly ground
4 brioche burger buns, split
4 Swiss cheese slices
4 leaves green leaf lettuce
2 ripe tomato, sliced
1/2 red onion, thinly sliced
1/4 cup mayonnaise

Instructions

1

In a small bowl, whisk together 1/4 cup extra-virgin olive oil, 2 tbsp balsamic vinegar, 2 tbsp soy sauce, 2 minced garlic cloves, 1/2 tsp smoked paprika, and 1/4 tsp freshly ground black pepper.
2

Wipe 4 stems removed large portobello mushroom caps clean and place them gill-side up in a shallow dish. Pour the marinade over them, spooning some into the gills. Let marinate for at least 15 minutes, flipping once.
3

Preheat the grill to medium-high heat (400°F / 200°C). Clean and oil the grates.
4

Grill the portobellos gill-side down for 5-6 minutes, then flip and grill for another 4-5 minutes until fully tender and juicy. In the last minute, place a slice of 4 Swiss cheese slices on each cap to melt.
5

Toast the 4 split brioche burger buns cut-side down on the grill for 1-2 minutes until golden.
6

Spread 1/4 cup mayonnaise on each bun. Layer 4 leaves green leaf lettuce, grilled portobello, 2 sliced ripe tomato slices, and 1/2 thinly sliced red onion. Serve immediately.

Questions

Can I make Grilled Portobello Burgers dairy-free?

Yes. The dairy in this entry is 4 Swiss cheese slices. Swap the cheese for a plant-based melting cheese (expect a milder flavor). The richness shifts slightly, but the method does not change.

Can I make Grilled Portobello Burgers gluten-free?

Yes. The gluten in this entry is 2 tbsp soy sauce, 4 brioche burger buns, split. Swap the soy-based sauce for tamari or coconut aminos; the bread or crumbs for a gluten-free loaf or gluten-free panko. Everything else proceeds as written.

How long does Grilled Portobello Burgers keep?

Refrigerate leftovers within two hours and eat them within three days. Reheat in a hot skillet rather than the microwave to keep the char.

Can I halve or double Grilled Portobello Burgers?

Yes. As written it serves 4. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. Doubling on the grill just takes more surface area; keep the heat zones the same.
