👨🍳 Instructions
- 1
Pat the chuck roast down and season it with salt and pepper.
- 2
Heat a large skillet over medium-high heat.
- 3
Add the butter and the oil to the skillet.
- 4
Once the butter has melted and starts to crackle, add the chuck roast and sear, about 2-3 minutes per side.
- 5
Transfer the roast to a plate.
- 6
Add 1/2 of the onions, the garlic, the beef broth, the Worcestershire sauce, the vinegar, the onion powder, the thyme, the bay leaf, the celery seeds, the sugar, and the seared chuck roast to a slow cooker.
- 7
Top the roast with the remaining 1/2 of the onions.
- 8
Cover and cook on low until the roast is fall-apart tender, about 6-8 hours.
- 9
Transfer the meat to a plate, covering it to keep it warm.
- 10
Combine the cornstarch and the water to create a slurry.
- 11
Add the slurry to the slow cooker and stir.
- 12
Allow the mixture in the slow cooker to cook until thickened, about 5-7 minutes. If the sauce still seems too thin, add additional cornstarch slurry, 1 tablespoon of cornstarch to every 2 tablespoons of water at a time, and cook for an additional 5 minutes.
- 13
Remove and discard the bay leaf.
- 14
Return the meat to the slow cooker and heat through. Serve.
💡 Pro Tips
- ✓Divide onions into two portions and layer them—bottom half under the roast, top half on top—because the bottom onions caramelize in the broth (converting 15-20% of their sugars to deeper Maillard compounds) while top onions stay slightly firmer, creating textural contrast.technique15-20% sugar conversion via Maillard reaction
- ✓Use a 1:1 ratio of butter to oil (2 tbsp butter + 1 tbsp oil) for searing because butter alone has a 350°F smoke point and will burn, while the oil raises the effective smoke point to 400°F, ensuring proper browning without acrid flavors.ingredient1:1 butter:oil ratio, 400°F effective smoke point
- ✓Sear the roast 2-3 minutes per side on medium-high heat to develop a 1/16-inch Maillard crust, but don't flip more than twice because extended contact is what creates the crust; multiple flips interrupts the browning process.timing2-3 minutes per side, 1/16-inch crust depth
- ✓Add the apple cider vinegar (1 tablespoon) to balance the onion sweetness and beef richness; the acidity (pH ~2.5) cuts through fat and prevents the dish from tasting cloying, while also tenderizing collagen by 10-15% through acid hydrolysis.ingredient1 tablespoon, pH ~2.5, 10-15% collagen breakdown
- ✓Cook on low for 6-8 hours because chuck roast collagen converts to gelatin around 160-170°F, but needs sustained time below 210°F to achieve full breakdown without toughening the muscle fibers from excessive heat.timing6-8 hours low heat, 160-170°F collagen conversion zone
