Make marinade by stirring together:

balsamic vinegar

olive oil


garlic, minced

fresh lemon juice

Set aside.

Scoop ribs and stem from portobello mushrooms.

Brush marinade on mushrooms.

Let rest for 30-40 minutes.

Grill 4-5 minutes per side, or roast.

Saute sliced red onions with a little olive oil and garlic, minced.


brioche slider rolls

grilled mushrooms

sauteed onions

fresh arugula

drizzle with:

balsamic glaze (not vinegar)


  • Make sure to use balsamic glaze, not vinegar. The glaze has a thicker consistency & is more sweet.
  • These are a nice meatless option when you’re grilling. They are good without a bun too.
