Ingredients for Marinated Portobello Mushrooms

For the Mushrooms and Marinade:

• 4 large Portobello mushrooms, cleaned and stems removed
• 1 tablespoon olive oil
• 2 tablespoons balsamic vinegar
• 2 cloves garlic, minced
• 1 teaspoon dried oregano
• 1 teaspoon dried thyme
• Salt and black pepper to taste

For the Optional Sides:

• 1 bunch of asparagus (optional, but adds color and flavor!)
• 4 medium-sized potatoes (for mashed potatoes)

Substitutions:

Feel free to use fresh garlic instead of minced for a stronger flavor.

If you don’t have balsamic vinegar, you can use red wine vinegar for a tangy twist.

How to Make Marinated Portobello Mushrooms

Step 1: Prepare the Marinade

Preheat your oven to 400°F (200°C). In a large bowl, whisk together olive oil, balsamic vinegar, minced garlic, oregano, thyme, salt, and pepper until well combined.

Step 2: Marinate the Mushrooms

Place the Portobello mushrooms and asparagus (if using) into an oven-safe skillet. Using a pastry brush, generously coat the tops and bottoms of the mushrooms and asparagus with the marinade. Let them sit for a few minutes to absorb the flavors.

Step 3: Bake the Mushrooms

Place the mushrooms top side down in the skillet and pour any remaining marinade over them. Bake for 20 minutes, then flip the mushrooms and continue baking for an additional 5-10 minutes until the mushrooms are tender and fully cooked.

Step 4: Make the Mashed Potatoes

While the mushrooms are baking, wash and peel the potatoes. Bring them to a boil in a pot of salted water until tender. Drain and mash using a potato masher or hand blender for extra smoothness. Stir in olive oil, salt, black pepper, and fresh herbs to taste.

Serve your marinated mushrooms and mashed potatoes immediately for the best results!

How to Store and Reheat Marinated Portobello Mushrooms

Storage:

• Store leftover mushrooms in an airtight container in the refrigerator for up to 2 days.

Reheating:

• To reheat, place the mushrooms in a skillet over medium heat for about 5 minutes, or warm them in the oven at 350°F (175°C) for 10 minutes.

Additional Tips and Recommendations

1. Try grilling the mushrooms – For a smoky flavor, grill the marinated Portobello mushrooms instead of baking them.
2. Add cheese – For extra flavor, sprinkle some grated Parmesan or vegan cheese on top of the mushrooms before baking.
3. Double the recipe – If you’re hosting a gathering, double the recipe and serve the mushrooms as an appetizer for your guests.

Frequently Asked Questions (FAQs)

1. Is it OK to eat the gills of a Portobello mushroom?
   Yes, the gills of Portobello mushrooms are perfectly edible. In some dishes, they might affect the look, but in this recipe, the marinade covers them, so no need to worry.
2. How long should I marinate Portobello mushrooms?
   Because mushrooms are very porous, it’s best not to marinate them for longer than 30 minutes. Any longer, and they may absorb too much liquid and become soggy.
3. Should I rinse Portobello mushrooms before cooking?
   Yes, lightly rinse the mushrooms under cool water and pat them dry with a paper towel. Avoid soaking them, as they can absorb water, which prevents them from soaking up the marinade.
