We looked to Julia Child for tips on this iconic French dish, but we’ve given it the Cook Smarts treatment to cut down on dishes and streamline the cooking process. Even with our shortcuts, the key to this rich stew is to develop layers of flavor by sauteing the ingredients in batches, so you'll need a little extra time to assemble this one. Finishing the dish in the slow cooker or oven at low heat will tenderize the meat and help to develop the flavors. Smarts #1: This is even better if made a day or two ahead, so feel free to make it when you have time and just reheat it to serve. Smarts #2: This recipe could be made in the Instant Pot.

Sweet potatoes / Carrots / Onions / Garlic - Prep as directed. Combine carrots and onions in one container. Store sweet potatoes and garlic in their own containers. (Can be done up to 5 days ahead)
Make vinaigrette - Whisk together vinegar, lemon juice, and mustard. Add olive oil while whisking. (Can be done up to 5 days ahead)
Mushrooms / Beef - Prep as directed. Store separately. (Can be done up to 3 days ahead)
Dry and season beef - Pat beef dry with paper towels. (This will help it to brown.) Season with some salt and pepper. (Can be done up to 3 days ahead)
Slow cook beef - Heat a Dutch oven over medium heat. Add cooking oil and then beef to heated oil. Cook on all sides until deep golden brown, 8 to 10 minutes. Transfer beef to a plate. In remaining fat in pan, saute carrots, onions, and mushrooms until onions are tender, ~5 minutes, adding some more oil if the pan starts to look dry. Add garlic, tomato paste, thyme, salt, and black pepper. Stir for 1 minute. Pour stock over vegetables and bring to a simmer. Add bay leaves. Return beef to pot and simmer everything together for 5 minutes. Transfer to a slow cooker and cook until the beef is very tender, low for 8 to 10 hours (high for 4 to 5 hours). (If you prefer to use the oven: Cover the Dutch oven, leaving the lid slightly ajar, and bake the dish in the oven at 325F / 163C for 2 hours.) (Can be done up to 2 days ahead)
