Ingredients

3 tablespoons vegetable oil (more as needed)
1 lb sirloin steak, cubed
1 -2 teaspoon fresh ground black pepper
7 large fresh button mushrooms, sliced (or use as much as desired)
1 large onion, chopped
1 -2 tablespoon fresh minced garlic (or to taste)
1 teaspoon dried thyme (can use a pinch more)
1 (1 ounce) package dry mushroom gravy mix
1 cup water
2 -4 teaspoons Worcestershire sauce
1 sheet frozen puff pastry, thawed according to package directions
1 egg
1 tablespoon cold water

Equipment Needed

Large skillet
Greased casserole dish (or a 10-inch very deep-dish pie plate)
Small cup
Whisk

Instructions

Begin by heating the vegetable oil in a large skillet over medium-high heat. You might need a little extra oil depending on how lean your sirloin is.
Season the steak cubes generously with fresh ground black pepper. Adding pepper at this stage helps it adhere to the meat and infuse its flavor as it cooks.
Add the seasoned steak to the hot skillet. Brown the steak on all sides, creating a rich, flavorful crust. Don’t overcrowd the pan; work in batches if necessary to ensure even browning. Once browned, remove the steak from the skillet and set it aside in a bowl.
Now, add the sliced mushrooms to the same skillet. Cook until they are nicely browned and have released their moisture. This step is crucial for developing the deep, earthy flavor of the filling.
Introduce the chopped onion and dried thyme to the skillet. Sauté for about 5 minutes, stirring occasionally, until the onion becomes softened and translucent. Add the fresh minced garlic during the last 2 minutes of cooking, allowing its pungent aroma to fill your kitchen. Be careful not to burn the garlic; it should be fragrant, not bitter.
Return the browned beef to the skillet, combining it with the mushrooms, onions, and garlic.
Incorporate the dry mushroom gravy mix into the skillet. Pour in 1 cup of water and add Worcestershire sauce, starting with 2 teaspoons and adjusting to taste. Worcestershire sauce adds a wonderful umami depth to the gravy. Bring the mixture to a simmer over low heat and cook for 30-35 minutes, allowing the flavors to meld together beautifully. Stir occasionally to prevent sticking. The gravy should thicken and coat the beef and mushrooms.
Taste and season the beef mixture with salt and black pepper to your liking. Remember that the gravy mix already contains sodium, so be cautious with the salt.
Preheat your oven to 400 degrees F (200 degrees C).
Transfer the luscious beef mixture to a greased casserole dish (or a 10-inch very deep-dish pie plate).
On a lightly floured surface, roll out the puff pastry to a size slightly larger than the top of the casserole dish. Carefully drape the puff pastry over the dish, covering the beef mixture completely. Gently press the edges of the puff pastry onto the rim of the dish to seal it securely. This will create a beautiful, puffed crust during baking.
In a small cup, whisk together the egg and 1 tablespoon of cold water to create an egg wash. Brush the egg wash evenly over the top of the puff pastry. The egg wash will give the crust a gorgeous golden-brown sheen.
Bake in the preheated oven for 20 minutes, or until the puff pastry is puffed up and golden brown. Keep a close eye on it; ovens vary, and you might need a few extra minutes to achieve the perfect color.

Expert Tips & Tricks

For an even richer flavor, consider browning the steak in bacon fat instead of vegetable oil. The smoky notes from the bacon will complement the beef and mushrooms beautifully.
If you’re short on time, stewing beef can be used instead of sirloin. Adjust the cooking time as needed to ensure the beef is tender.
Don’t discard the mushroom stems! They are packed with flavor. Finely chop them and add them to the skillet along with the sliced mushrooms.
A splash of red wine added during the simmering stage will enhance the depth of flavor in the gravy.
To prevent the pastry from puffing up unevenly, you can dock it with a fork before brushing with egg wash.
If the crust starts to brown too quickly, tent it loosely with foil to prevent burning.
For a more rustic look, don’t worry about making the pastry edges perfectly neat. A slightly imperfect crust adds to the charm of this hearty pie.

Serving & Storage Suggestions

Serve the Steak & Mushroom Puff Pastry Pie hot from the oven, allowing it to cool slightly before slicing. A side of mashed potatoes, roasted vegetables, or a simple green salad makes a perfect accompaniment.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, warm the pie in a preheated oven at 350 degrees F (175 degrees C) until heated through. You can also reheat individual slices in the microwave, but the crust may become slightly soggy.

For longer storage, the cooked beef filling can be frozen for up to 2 months. Thaw overnight in the refrigerator before using. The unbaked pie can also be assembled and frozen. When ready to bake, thaw completely and bake as directed.
