5Brown the beef in two batches in a Dutch oven with 1 teaspoon of vegetable oil over medium-high heat.
6Cut the portabella mushroom into 1/2 inch pieces.
7Add the mushrooms to the Dutch oven and cook over medium heat using the fat left from browning the beef. Cover and let the mushrooms sweat for 5-10 minutes.
8Remove the woody stem from the kale and cut the leaves crosswise into 1/2 inch slices. Wash in a salad spinner.
9Cut the parsnips lengthwise, then crosswise into 1-inch pieces.
10Once the mushrooms have sweated, cook until browned (5-10 minutes).
11Add 1 tablespoon of vegetable oil, 2 chopped onions, 3 cloves of minced garlic, and 1 tablespoon of fresh thyme.
12Cook for 30 seconds to bloom the garlic.
13Add 3 tablespoons of all-purpose flour and 1 tablespoon of tomato paste. Stir to combine and ensure no dry bits of flour remain.
14Add 1.5 cups of red wine, whisking to dissolve the flour.
15Add 2 cups of beef broth and 2 cups of chicken broth. Whisk to combine and ensure there are no lumps.
16Add 2 bay leaves.
17Add the browned beef and any accumulated juices from the bowl.
18Bring the stew to a simmer, cover, and cook in a 300°F oven for 1 hour and 30 minutes.
19After 1 hour and 30 minutes, add the parsnips, carrots, and potatoes (all cut into 1-inch pieces). Stir.
