Instructions

In a medium bowl, whisk together olive oil, lemon juice (or vinegar), minced garlic, dried oregano, Dijon mustard, salt, and pepper. Stir in soy sauce or maple syrup if using.
Place portobello mushrooms in a shallow dish or zip-top bag. Pour marinade over the mushrooms, turning to coat well on all sides.
Let the mushrooms marinate for at least 30 minutes, up to 2 hours. For best flavor, turn them occasionally so every side absorbs the marinade.
Preheat grill, oven, or skillet to medium-high. Remove mushrooms from marinade and shake off excess.
Grill or roast mushrooms for 5–7 minutes per side, or until tender and caramelized at the edges. If using a skillet, cook for 4–6 minutes per side.
Slice and serve warm or cold. Garnish with fresh herbs if desired. Enjoy as a main, side, in sandwiches, salads, or bowls!

Notes

Try different acids like red wine vinegar, lime juice, or orange juice for a twist. For a Mediterranean vibe, add capers or a pinch of chili flakes. Marinated mushrooms keep well in the fridge for up to 3 days—great for meal prep, sandwiches, or salads. Don’t over-marinate for more than 24 hours to keep the texture just right.
