Another one, because I came across it and wanted to remember it for later:
Healthy & Delicious: Mushroom 'Bolognese' | Serious Eats : Recipes
Ingredients
serves 3 or 4, active time 20 minutes, total time 40 minutes
1 tablespoon extra virgin olive oil
2 large shallots, finely chopped (about 1/4 cup)
1 large carrot, peeled and finely chopped (about 1/2 cup)
10 ounces button mushrooms, finely chopped
Kosher salt
Freshly ground black pepper
1 (14.4-ounce) can diced tomatoes
2 teaspoons chopped fresh oregano
Procedures
In a 10-inch heavy-bottomed skillet pan, heat oil over medium-high heat until shimmering. Add shallots, carrot, and mushrooms. Season to taste with salt and pepper. Cook, stirring occasionally, until mushrooms have reduced and their liquids have almost evaporated, about 12 minutes. Add tomatoes and oregano. Stir to combine. Cook, stirring occasionally, until sauce thickens to desired consistency. Serve with wide, flat pasta like pappardelle or tagliatelle or ridged pasta like rotini or rigatoni.
