This mushroom stew is made with a mix of mushrooms, veggies and beans in a white wine tomato base and seasoned with rosemary. It's delicious, comforting, and perfect with a big piece of crusty bread!
Start by cooking the mushrooms in batches (Note 3). Coat the bottom of a large skillet with about 2 tablespoons of olive oil and place it over medium heat.
When the oil is hot, add a layer of mushrooms. Cook the mushrooms for about 5 minutes on each side, until browned, then transfer them to a plate. Cook subsequent batches of mushrooms in the same manner, until they're all cooked. Add oil to the skillet as needed.
While the mushrooms are cooking, start the stew. Coat the bottom of a large pot with a tablespoon of olive oil and place it over medium heat.
Once the oil is hot, add the celery, carrots, and onions. Sweat the veggies, stirring occasionally, until they start to soften, about 10 minutes.
Stir in the garlic and cook it with the vegetables for about 1 minute, until very fragrant, stirring constantly.
Stir in the wine and bring it to a simmer. Let the wine cook for about 4 minutes, until reduced by about half.
Stir in the cooked mushrooms, tomatoes, beans, broth, tomato paste, and whole sprigs of rosemary. Raise the heat and bring the stew to a boil. Lower the heat and allow it to simmer for about 30 minutes, stirring occasionally, until the base has thickened and the veggies are soft.
Remove the pot from heat. Remove the rosemary sprigs and season the stew with salt and pepper to taste.
Ladle into bowls and serve.
