The best part about this — well, besides all of it, — is that it’s a bourguignon without the heft of beef, but all of the indulgence. Plus, since you don’t need to braise it in the oven for three hours, it can be a weekday night dinner.
2 tablespoons olive oil
2 tablespoons butter, softened
2 pounds portobello mushrooms, in 1/4-inch slices (save the stems for another use) (you can use cremini instead, as well)
1/2 carrot, finely diced
1 small yellow onion, finely diced
2 cloves garlic, minced
1x cup full-bodied red wine
2 cups beef broth
2 tablespoons tomato paste
1 tsp fresh thyme leaves (1/2 teaspoon dried)
1 1/2 tablespoons all-purpose flour
1x cup pearl onions, peeled (thawed if frozen)
Egg noodles, for serving
Sour cream and chopped chives or parsley, for garnish (optional)
Heat 1 tbsp of olive oil and 1 tbsp of butter in a medium Dutch oven or heavy saucepan over high heat. Sear the mushrooms until they begin to darken, but not yet release any liquid — about three or four minutes. Remove them from pan.
Lower the flame to medium and add the second tbsp of olive oil. Toss the carrots, onions, thyme, a few good pinches of salt and a several grinds of black pepper into the pan and cook for 10, stirring occasionally, until the onions are lightly browned. Add the garlic and cook for just one more minute.
Add the wine to the pot, scraping any stuck bits off the bottom, then turn the heat all the way up and reduce it by half. Stir in the tomato paste and the broth. Add back the mushrooms with any juices that have collected and once the liquid has boiled, reduce the temperature so it simmers for 20 minutes, or until mushrooms are very tender. Add the pearl onions and simmer for five minutes more.
Combine remaining butter and the flour with a fork until combined; stir it into the stew. Lower the heat and simmer for 10 more minutes. If the sauce is too thin, boil it down to reduce to the right consistency. Season to taste.
To serve, spoon the stew over a bowl of egg noodles, dollop with sour cream (optional) and sprinkle with chives or parsley.
