Instructions

1. Prepare the Beef
Pat the beef chuck roast dry and season all sides with salt and pepper.
2. Sear the Roast
In a large skillet, heat olive oil over medium-high heat. Sear the roast on all sides until browned (about 3–4 minutes per side). Transfer to the slow cooker.
3. Add Vegetables
Add onion, garlic, carrots, and celery around the roast in the slow cooker.
4. Make the Broth Mixture
In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, thyme, rosemary, and bay leaves. Pour over the roast and vegetables.

Drain well and return potatoes to pot. Add butter and milk; mash until smooth and creamy. Season with salt and pepper to taste. Add more milk if needed for desired consistency.
7. Rest and Shred Beef
Remove the roast from the slow cooker and let rest for 5 minutes. Discard bay leaves. Shred or slice the beef.

Zusatztipps für die Zubereitung

Für eine dickere Soße nehmen Sie ½ Tasse der Kochflüssigkeit ab, verquirlen sie mit 1 EL Maisstärke und rühren sie zurück in den Slow Cooker. Dort 10 Minuten auf hoher Stufe kochen lassen. Verwenden Sie statt Rinderbrühe einen halben Becher Rotwein für ein besonders intensives Aroma. Die Wahl von Yukon-Gold-Kartoffeln sorgt für eine cremige, buttrige Konsistenz der Kartoffelpüree, aber auch Russet-Kartoffeln sind gut geeignet.

Varianten und Anpassungen

Dieses Gericht lässt sich leicht an verschiedene Ernährungsbedürfnisse anpassen, zum Beispiel durch die Verwendung von glutenfreier Brühe und Worcestershire-Sauce. Für eine reichhaltigere Geschmacksvariante können zusätzlich Pilze oder rote Paprika in den Slow Cooker gegeben werden. Um es vegetarisch zu gestalten, kann das Rezept auf Pilze oder Seitan mit geeigneter Brühe umgestellt werden, allerdings fällt dann die klassische Fleischnote weg.

Serviervorschläge

Servieren Sie das Pot Roast zusammen mit den gedünsteten Gemüse aus dem Slow Cooker auf einem Bett aus cremigem Kartoffelpüree. Ein frischer Petersilienzweig als Garnitur bringt zusätzliche Farbe und Frische. Als Getränk empfehlen wir einen kräftigen Rotwein wie Cabernet Sauvignon, der das herzhafte Aroma des Fleisches hervorragend unterstützt.
