Cuisine: American

Ingredients

1 stick butter
1½ –2 pounds chuck roast
2 large onions thinly sliced
2 tablespoons Worcestershire sauce
2 tablespoons olive oil
2 cups beef broth
1 packet Dano’s Dips French Onion Seasoning
2 tablespoons Dano’s Outlaw Butter Seasoning

Method

Preheat the Oven

Preheat your oven to 350°F.

Season the Roast

Pat the chuck roast dry and generously season all sides with Dano’s Outlaw Butter Seasoning.

Sear the Roast

Heat a large cast iron skillet over medium-high heat. Add the butter and olive oil.
Once melted and sizzling, add the chuck roast and sear on both sides until deeply browned. This step builds flavor.
Remove the roast and push it to the side of the skillet.

Cook the Onions

Add the sliced onions directly into the skillet. Cook for 5–7 minutes, stirring occasionally, until softened and lightly golden.

Build the French Onion Base

Pour in the beef broth and Worcestershire sauce. Sprinkle the entire packet of Dano’s French Onion Dip Seasoning over the onions and liquid. Stir gently to combine.

Return the Roast

Nestle the chuck roast back into the skillet. Sprinkle a little extra Outlaw Butter Seasoning over the top.

Bake Until Fall-Apart Tender

Cover the skillet tightly with aluminum foil and transfer to the oven.
Bake at 350°F for 2½–3 hours, or until the roast is fork-tender and easily shreds.

Serve

Shred the roast directly in the skillet and spoon the onions and juices over the top.
Serve over mashed potatoes, roasted potatoes, egg noodles, or pile onto slider rolls for game day. Touchdown.
