Mmm, pesto! I’ve sung its praises before, but I really have yet to exhaust its culinary potential. Here, it adds flavor and a nutritional boost to brown rice stuffed portobello mushrooms. The protein-rich cashew cream sauce rounds out this dish, which works equally well as a side dish or a vegetarian entree.
Pesto-Stuffed Mushrooms with Marsala Cream Sauce
For the mushrooms:
6 portobello mushrooms, stems removed
3 cups cooked brown basmati rice
1 cup homemade pesto
1/4 cup vegetable broth
1 large, ripe tomato
For the cream sauce:
1/2 cup raw cashews
1 red onion
1 tsp olive oil
1/4 cup Marsala wine
1 cup vegetable broth
1/4 tsp salt
Soak raw cashews in 1 cup cold water for at least 1 hour.
Preheat oven to 350 F. Line a baking sheet with foil or parchment. Lay out the mushrooms, top sides down.
Combine the pesto and cooked brown rice. Add the egg and broth, and mix until well combined. Spoon 1/2 cup of filling into each mushroom cap. Slice the tomato and top each stuffed mushroom with 1 slice of tomato. Bake for 30 minutes.
Meanwhile, chop the onion. Heat the oil in a skillet over low to medium-low heat and sweat the onion until translucent, about 10 minutes. Raise the heat to medium-high and add the Marsala. Simmer until the wine has reduced to almost nothing. Add broth and salt, and bring to a simmer. Remove from heat and let cool for about 5 minutes.
Drain the soaking cashews. Combine cashews and hot broth mixture in a high-powered blender and puree until velvety smooth.
Serve the stuffed mushrooms warm, with cashew cream sauce on the side or drizzled over top.
