Recipe Background

We are big fans of casseroles around here, especially when we take our favorite standalone dishes and turn them into a simpler, (usually) more flavorful version, thanks to baking it in the oven! Take Steak Diane Casserole for example. It incorporates the savory flavors you love from the original and turns it into a juicier, even more tender version! Sure, it takes a little bit of time to bake, but that's another reason why we love this bubbly bake so much — you throw it together and let the oven do the hard work for you. Steak Diane Casserole is really a delicious upgrade!

Ingredients

  • 2 tablespoons vegetable oil
  • 3 pounds braising beef chopped into bite-sized chunks
  • 3 tablespoons all-purpose flour
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper plus more, to taste, for garnish
  • 1 large onion chopped
  • 4 cloves garlic minced
  • 2 tablespoons tomato paste
  • 4 tablespoons brandy
  • 1 tablespoon Worcestershire sauce
  • 4 1/4 cups beef stock plus more, to taste
  • 10 1/2 ounces chestnut mushrooms
  • 1 tablespoon cornstarch
  • 3 tablespoons cold water
  • 1/2 cup heavy cream
  • 1 small bunch fresh parsley roughly chopped, for garnish

Directions

  • Preheat the oven to 320 degrees F.
  • In a large Dutch oven over high heat, add the vegetable oil.
  • In a large bowl, add the beef pieces, the flour, the salt, and 1/2 teaspoon of the black pepper and gently toss to coat.
  • Add the coated beef pieces to the heated oil and cook, flipping occasionally, until they are browned all over, about 6-8 minutes.
  • Reduce the heat to medium. Add the onions to the beef and cook, stirring frequently, until the onions start to soften, about 3-4 minutes.
  • Add the garlic and the tomato paste to the beef mixture and cook, about 1 minute.
  • Add the brandy, the Worcestershire sauce, 4 1/4 cups of the beef stock, and the mushrooms to the beef mixture, then use a wooden spoon to combine and loosen any of the browned bits from the bottom of the Dutch oven.
  • Bring the beef mixture to a boil.
  • Place the lid on the Dutch oven and transfer it to the oven. Bake the beef casserole until the meat is tender, about 3 hours. Note: Occasionally check on the casserole during the last hour of cooking to ensure it isn't too dry. If it is, add the extra beef stock.
  • In a small bowl, add the cornstarch and the water and whisk to combine.
  • Transfer the beef casserole to a wire rack. Add the slurry and the heavy cream and stir to combine.
  • Serve the beef casserole garnished with the parsley and the extra black pepper.
