Ingredients You’ll Need
(6-quart slow cooker)
For the Roast & Onions:
3–4 lbs (1.4–1.8 kg) beef chuck roast, trimmed
3 tbsp olive oil
4 large yellow onions, thinly sliced
4 cloves garlic, minced
2 cups (480ml) beef broth (low-sodium)
½ cup (120ml) dry red wine (like Cabernet) or extra broth
2 tbsp Worcestershire sauce
1 tbsp tomato paste
1 tsp fresh thyme leaves (or ½ tsp dried)
1 bay leaf
Salt & black pepper to taste
For the Cheesy Topping (Optional but Recommended):
1 cup (4 oz) shredded Gruyère or Swiss cheese
4–6 oven-toasted baguette slices or croutons
 Pro Tips:
Sear the roast first—adds depth (skip if short on time).
Slice onions thin—they melt into the sauce.
Deglaze the pan with broth to capture all the flavorful bits.
Step-by-Step Instructions (Savory, Tender, Foolproof)
1. Sear the Roast (Optional but Recommended)
Pat roast dry; season with salt and pepper.
Heat 1 tbsp oil in a skillet over medium-high heat. Sear roast on all sides until deeply browned (6–8 mins total). Transfer to slow cooker.
2. Caramelize Onions (Shortcut Method)
In same skillet, add 2 tbsp oil. Cook onions over medium-low heat 10–15 mins, stirring occasionally, until softened and golden.
Add garlic; cook 1 minute. Stir in tomato paste; cook 1 more minute.
Deglaze with ½ cup broth, scraping up browned bits.
3. Slow Cook to Perfection
Pour onion mixture over roast in slow cooker.
Add remaining broth, wine, Worcestershire, thyme, and bay leaf.
Cover and cook on LOW for 8–9 hours or HIGH for 5–6 hours, until fork-tender.
4. Finish & Serve
Remove roast; shred or slice. Skim excess fat from sauce if desired.
Return meat to pot; discard bay leaf.
Option 1 (Classic): Ladle stew into bowls; top with toasted bread and cheese.
Option 2 (Broiled Crust):
Spoon into oven-safe bowls.
Top with toasted baguette slices and cheese.
Broil 2–3 minutes until bubbly and golden.
