Old-Fashioned Cajun Classic Roast | Cajun 911 Cuisine
This is the old-school Cajun way of cooking a roast. A mustard-coated chuck roast seasoned simply, piled high with onions, and slow-braised in the oven until fork-tender. The onions melt down into a deep, savory gravy made for French bread dipping and Sunday dinner plates with greens and glazed carrots. No shortcuts. No fuss. Just real Louisiana comfort food.
INGREDIENTS
FOR THE ROAST
1 (3–4 lb) chuck roast
3–4 Tbsp yellow mustard
1–1 1/2 Tbsp Cajun seasoning
1/2 tsp garlic powder
1/2 tsp black pepper
Optional dash Worcestershire sauce
FOR THE POT
3–4 large onions, thick sliced
3 garlic cloves, smashed
2–3 Tbsp vegetable oil or butter, for searing
1 cup beef broth
Optional 1 bay leaf
FOR SERVING
Steen’s glazed carrots
Braised greens such as mustard, turnip, or collards
French bread for dipping
INSTRUCTIONS
1. Prepare the Roast
Pat the chuck roast dry. Coat all sides with yellow mustard. Season evenly with Cajun seasoning, garlic powder, and black pepper. Add a dash of Worcestershire if using.
2. Sear the Roast
Heat a cast iron pot or heavy Dutch oven over medium-high heat. Add oil or butter. Sear the roast on all sides until deeply browned.
3. Add Onions the Old Cajun Way
Do not sauté the onions. Pile all sliced onions directly on top of the roast. Add smashed garlic around the roast. Pour beef broth around the sides, not over the top. Add bay leaf if using.
4. Oven-Braise
Cover tightly. Bake at 300°F for 3–4 hours. The onions will brown naturally in the oven and create a rich gravy. Roast is done when it pulls apart easily.
5. Serve
Serve hot with glazed carrots, braised greens, and French bread. Spoon the onion gravy generously over the meat.
