Pat the chuck roast dry with a paper towel. Season with salt and pepper. Heat the pan/skillet to medium-high. Add 2 tbsp butter, olive oil and wait for it to get hot. Sear the roast chunk for 4-5 minutes per-side. Remove the roast and set aside.

Add 2 tbsp butter and wait for it to melt. Add sliced onions and sauté for 10-12 minutes or until caramelized. Add minced garlic and sauté for 1 minute.

Place the seared roast in the slow cooker. Add cajun seasoning, caramelized onion, beef broth & bay leaves.

In a small bowl: combine cornstarch and water, mix until the cornstarch is fully dissolved. Transfer the broth to a pan. Add cornstarch mixture and mix.

Add cornstarch mixture to the slow cooker and simmer for 20 minutes or until desired consistency. Season with salt & pepper to taste.

Pour 1-2 cups of gravy over the shredded meat and mix. Toast Bread – Preheat the oven to 300°F (148°C). Slice the bread in half (vertically). Spread melted butter/ mayo on the inside of the bread. Lay the bread butterside down on a baking pan. Bake for 2-3 minutes. Remove bread from the oven.
