Several hours of cook time makes the meat butter-knife tender—and just 10 to 15 minutes for the vegetables keeps them bright in color and perfectly fresh so that everything is at its best taste and texture.
Serves 4
Prep: 25 minutes
Slow Cook: 7 hours (low) or 3½ hours (high)
Total: 7 hours 35 minutes
1 large sweet onion, halved and cut lengthwise into thin wedges
1 green bell pepper, thinly sliced lengthwise
1 boneless beef arm roast (2½ to 3 pounds), trimmed
Salt and black pepper
3 tablespoons coconut aminos
4 cloves garlic, minced
2 tablespoons grated fresh ginger
1 teaspoon sesame oil
2 cups snow peas, trimmed
8 ounces shiitake mushrooms, stemmed and sliced
1 bunch green onions, white and green parts, cut into 1-inch pieces
In a 5- to 6-quart slow cooker, combine the onion and bell pepper. Season the beef with salt and pepper and add to the slow cooker. In a small bowl, combine the coconut aminos, garlic, ginger, and sesame oil. Drizzle over the beef.
Cover and cook on low for 7 to 8 hours or on high for 3½ to 4 hours, or until tender. Remove the roast from the cooker. Cover with foil to keep warm.
Turn the slow cooker to high if using the low setting. Stir the snow peas, mushrooms, and green onions into the slow cooker. Cover and cook until the snow peas are crisp-tender and mushrooms are softened, 10 to 20 minutes. Slice or shred the beef and serve with the vegetables and mushrooms.
Instant Pot Variation Follow the directions in the first step using a 6-quart Instant Pot. Lock the lid in place. Select Manual and cook at high pressure for 45 minutes. Use natural release for 10 minutes, then quick release. Add the vegetables, select Sauté, and adjust to Less/Low. Simmer, uncovered, until the snow peas are crisp-tender and the mushrooms have softened, 10 to 20 minutes. Continue with the remaining directions.
