Pressure Cooker Mushroom and Wild Rice Soup
This comforting soup tastes long-simmered, but it’s cooked in a pressure cooker, which makes it a weeknight possibility (though you could also make this recipe in a slow cooker). Use any variety of mushrooms you like: Cremini (also called baby bella) are affordable and easy to find and work well, or you can add shiitake or oyster mushrooms for a mix of texture and flavors. Don’t worry about removing small, supple stems, but discard any that are tough or dried-out. Wild rice isn’t a true rice at all but the seed of a grass that’s native to North America. When it’s cooked, it should be pleasantly chewy and nutty, not hard, and most of the grains should be slightly split open to reveal their creamy insides.
- Serves: 6 persons
- 4tablespoons unsalted butter (1/2 stick)
- 1yellow or red onion, minced
- 2pounds mixed mushrooms (such as cremini and shiitake), tough stems removed, mushrooms chopped into 1/2- to 1-inch pieces
- Kosher salt and black pepper
- 2celery stalks, chopped
- 1large carrot, peeled and chopped
- 6garlic cloves, smashed and chopped
- 3sprigs fresh thyme or 1 teaspoon dried thyme
- 1teaspoon garlic powder
- ¼cup all-purpose flour
- 5cups vegetable or chicken stock
- ½cup dry white wine (see Tip)
- 1cup wild rice (about 6 ounces)
- ½cup sour cream
- Chopped scallions or chives and fresh dill, for topping
Step 1Turn on the sauté setting on a 6- to 8-quart electric pressure cooker. Melt the butter, then add the onion. Cook, stirring occasionally, until translucent, about 5 minutes.
Step 2Add the mushrooms and 1 teaspoon salt, and cook, stirring occasionally, until the mushrooms have released their liquid and shrunk a bit, about 8 minutes. Add the celery, carrot, chopped garlic, thyme, garlic powder and several generous grinds of black pepper. Stir to combine. Add the flour and stir until the vegetables are evenly coated and no white spots remain.
Step 3Pour in the stock and wine, and turn off the heat. Scrape the bottom of the pot very well to incorporate flour and any browned bits that are stuck to the bottom. (This will add flavor and also prevent a burn warning later.) Stir in the wild rice.
Step 4Cook on high pressure for 10 to 12 minutes. Turn off the heat and let the pressure reduce naturally for 10 minutes, then release the remaining pressure manually.
Step 5Stir the soup and check the texture of the wild rice; if it needs a bit more time repeat the pressure cooking process for a cook time of 2 minutes and rapidly release the pressure. Check the texture of the soup; if you’d like it to be thicker, turn on the sauté function and let the soup simmer to reduce to desired consistency. Turn off the heat.
Step 6Put the sour cream in a small bowl and slowly whisk in a few spoonfuls of warm soup until smooth, then stir the mixture into the soup. (This prevents the sour cream from separating.) Taste the soup and add salt and pepper to taste.
Step 7Serve the soup in bowls topped with chopped scallions or chives and dill. Reheat any leftovers on low until warm. (Boiling can cause the sour cream to break.)
