Ingredients

• 1.5 lbs beef chuck, cut into 1-inch cubes
• 3 medium, peeled and sliced into 1/2-inch rounds carrots
• 2 medium, peeled and sliced into 1/2-inch rounds parsnips
• 1 large, diced yellow onion
• 4 cloves, minced garlic cloves
• 3 cups beef broth
• 2 tbsp tomato paste
• 1/2 cup red wine
• 2 tbsp olive oil
• 1 tbsp chopped fresh thyme
• 1 bay leaf
• 1 tsp salt
• 1/2 tsp black pepper
• 1 tbsp cornstarch
• 2 tbsp cold water

Instructions

1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add 1.5 lbs beef chuck cubes and brown them on all sides for about 5-7 minutes; transfer browned beef to the slow cooker.
2. Step 2: In the same skillet, add 1 large diced yellow onion and sauté for 4 minutes until translucent. Add 4 minced garlic cloves and cook for 1 minute until fragrant.
3. Step 3: Transfer onions and garlic to the slow cooker with the beef. Add 3 sliced carrots, 2 sliced parsnips, 3 cups beef broth, 1/2 cup red wine, 2 tbsp tomato paste, 1 tbsp chopped fresh thyme, 1 bay leaf, 1 tsp salt, and 1/2 tsp black pepper.
4. Step 4: Stir to combine, cover, and cook on low for 7-8 hours or on high for 4-5 hours until beef is tender and vegetables are soft.
5. Step 5: About 30 minutes before serving, mix 1 tbsp cornstarch with 2 tbsp cold water to make a slurry. Stir the slurry into the stew to thicken the sauce. Cook uncovered on high for 25-30 minutes until the stew thickens and coats the back of a spoon.
6. Step 6: Remove the bay leaf before serving. Adjust seasoning if needed and ladle stew into bowls.
