Recipe Information
Ingredients
- 4 pieces portobello mushrooms (large, stems removed)
- 2 tablespoons olive oil
- 2 tablespoons soy sauce
- 1 tablespoon balsamic vinegar
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- 2 teaspoons black peppercorns
- 3 tablespoons vegetable broth
- 1 tablespoon unsalted butter (vegetarian, or substitute with plant-based alternative)
- 1 cup heavy cream (or plant-based cream for a vegan option)
- 1 teaspoon cornstarch
- 2 tablespoons water
- 1 tablespoon parsley (fresh, chopped, optional for garnish)
Instructions
Preheat your oven to 375°F (190°C).
In a small bowl, mix olive oil, soy sauce, balsamic vinegar, smoked paprika, and garlic powder to prepare the marinade.
Brush the portobello mushrooms generously with the marinade, ensuring both sides are coated. Let them sit for 10 minutes to absorb the flavors.
Place the marinated mushrooms on a baking sheet lined with parchment paper or lightly greased. Bake for 20 minutes, flipping them halfway through the cooking time to ensure even caramelization.
While the mushrooms are baking, prepare the peppercorn sauce. Lightly crush the black peppercorns using a mortar and pestle or the back of a spoon.
In a small saucepan over medium heat, melt the butter (or plant-based alternative). Add the crushed peppercorns and toast them for about 1 minute to release their aroma.
Stir in the vegetable broth and cream. Bring the mixture to a gentle simmer and let it cook for 3–4 minutes, stirring occasionally.
In a small bowl, mix the cornstarch and water to create a slurry. Slowly add this to the saucepan, whisking constantly, to thicken the sauce. Simmer for an additional 2 minutes until the sauce reaches your desired consistency.
Remove the baked portobello mushrooms from the oven and plate them as vegetarian steaks.
Generously pour the peppercorn sauce over the mushrooms and garnish with chopped parsley, if desired.
Serve immediately with your favorite sides, such as mashed potatoes or roasted vegetables.
