Step 1: Prepare the Marinade

1. Combine the Marinade Ingredients: In a medium mixing bowl, whisk together the olive oil, balsamic vinegar, soy sauce, maple syrup, Dijon mustard, minced garlic, smoked paprika, black pepper, dried thyme, and salt until smooth.
2. Taste and Adjust: Taste the marinade and adjust the seasonings as needed. For a sweeter glaze, add more maple syrup; for extra saltiness, add a dash more soy sauce.

This marinade brings together savory, smoky, and slightly sweet flavors, creating the perfect base for a rich, steak-like taste.

Step 2: Marinate the Mushrooms

1. Add the Mushrooms: Place the portobello mushroom caps in a shallow dish or a large resealable plastic bag. Pour the marinade over the mushrooms, ensuring each cap is well-coated.
2. Marinate: Allow the mushrooms to marinate for 15-20 minutes, flipping them halfway through. This will allow the mushrooms to absorb the flavors, enhancing their umami richness.

Marinating the mushrooms creates a deep, savory flavor that mimics the complexity of a steak marinade.

Step 3: Cook the Portobello Mushroom Steaks

Option 1: Pan-Searing

1. Heat the Oil: In a large skillet, heat 1-2 tablespoons of olive oil over medium-high heat.
2. Sear the Mushrooms: Place the marinated mushroom caps in the skillet, cooking each side for 4-5 minutes, or until they are golden-brown and slightly crispy on the edges. Use a spatula to press down gently on the mushrooms to help them release their juices.
3. Reduce Heat and Finish Cooking: Lower the heat to medium and cook for an additional 2 minutes, allowing the mushrooms to soak up any remaining marinade in the skillet.

Option 2: Grilling

1. Preheat the Grill: Preheat your grill to medium-high heat. Lightly oil the grates to prevent sticking.
2. Grill the Mushrooms: Place the mushroom caps on the grill and cook for 4-5 minutes per side, or until they are tender and have visible grill marks. Baste with extra marinade if desired.

Grilling gives the mushrooms a smoky, charred flavor that adds to the steak-like experience.

Step 4: Garnish and Serve

1. Garnish with Fresh Parsley: Sprinkle the cooked mushroom steaks with chopped fresh parsley for a burst of color and flavor.
2. Serve Hot: Serve the mushroom steaks hot with your favorite sides, such as mashed potatoes, roasted vegetables, or a fresh side salad.

These mushroom steaks are best enjoyed immediately, with their rich flavors and juicy texture at their peak.
