Ingredients

Tip: You can find the full list of ingredients and measurements in the recipe card below.

3 lb (≈1.4 kg) boneless pot roast (chuck)
3 tbsp extra virgin olive oil, divided
1 tsp fine sea salt
1 tsp freshly ground black pepper
3 lbs yellow onions (about 8 medium-large), sliced
2 cloves garlic, finely chopped
1 tbsp pure maple syrup or brown sugar
1 tbsp all-purpose flour (or gluten-free flour)
2½ cups beef stock
1 sprig fresh rosemary or a small handful of thyme
1 bay leaf

Step-by-Step Instructions

Step 1: Sear the Roast

Heat 1 tablespoon of olive oil in a Dutch oven over medium heat. Season the roast with half the salt and pepper. Brown on all sides—2–3 minutes per side—then remove and set aside.

Step 2: Caramelize the Onions

Add the remaining oil and all the sliced onions to the pot. Cook over medium heat until translucent, about 5 minutes. Reduce heat and continue cooking for 20 minutes until they turn light golden, stirring often to prevent burning.

Step 3: Add Garlic & Sweetener

Stir in garlic and maple syrup (or sugar). Continue cooking for 7–8 minutes until onions are deeply caramelized.

Step 4: Build the Braising Liquid

Sprinkle flour over the onions and stir to coat. Deglaze with beef stock , scraping up browned bits. Return the roast to the pot, nestle in herbs, and bring to a simmer.

Step 5: Slow-Braise

Cover the pot and bake at 300°F (150°C) for 3 hours. Then turn the roast over and pull it into a few pieces—should shred easily with two forks. Cover and return to the oven for another 30–45 minutes, until meltingly tender.

Step 6: Rest & Serve

Remove from oven and let cool. Refrigerate overnight in the pot to let flavors develop even more. When ready to serve, gently reheat and pair with mashed potatoes, polenta, or egg noodles.
