Gathering Your Ingredients for Brisket Hashbrown Casserole

Here is everything you will need to make this brisket hashbrown casserole, along with a quick note on what each ingredient brings to the dish.

• Cooked shredded brisket (3 cups): The star of the recipe, adding rich, beefy flavor and tender, meaty texture throughout the casserole.
• Frozen shredded hash browns, thawed (32 oz): The hearty potato base that soaks up the creamy sauce and bakes into a soft, comforting layer.
• Unsalted butter (2 tbsp): Used to sauté the onion and garlic, adding richness and a gentle buttery flavor to the base of the dish.
• Diced yellow onion (1 cup): Brings sweetness and aromatic depth, forming a flavorful foundation for the casserole.
• Garlic, minced (2 cloves): Adds a warm, savory note that enhances the brisket and creamy sauce.
• Kosher salt (1 tsp): Balances and heightens all the flavors in the casserole.
• Black pepper (0.5 tsp): Adds gentle heat and complexity without overpowering the other ingredients.
• Smoked paprika (1 tsp): Echoes the smoky character of the brisket and adds a subtle, earthy warmth.
• Dried thyme (0.5 tsp): Provides a mild herbal note that pairs beautifully with beef and potatoes.
• Sour cream (1 cup): Creates a tangy, creamy base that keeps the casserole moist and flavorful.
• Condensed cream of mushroom soup (10.5 oz can): Adds body and savory creaminess, tying the sauce together easily.
• Whole milk (1 cup): Loosens the sauce to the perfect consistency so it coats the hash browns and brisket evenly.
• Shredded sharp cheddar cheese, divided (2.5 cups): Melted into the filling for cheesy richness and sprinkled on top for a bubbly, golden crust.
• Chopped fresh parsley, divided (0.25 cup): Adds freshness and color, brightening the finished casserole.
• Panko breadcrumbs (0.5 cup): Create a light, crisp topping that contrasts with the creamy interior.
• Olive oil (1 tbsp): Helps the panko brown evenly and stay crunchy in the oven.

• Worcestershire sauce (1 tbsp): Brings a deep savory note that enhances the brisket and overall sauce.

How to Make Brisket Hashbrown Casserole Step by Step

Follow these straightforward steps and you will have a bubbling, golden brisket hashbrown casserole ready to share.

1. Preheat the oven and prepare the dish. Set your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with a little butter or nonstick spray so the casserole releases easily after baking.
2. Thaw and dry the hash browns. If your frozen shredded hash browns are still icy, spread them out in a large bowl or on a tray and let them thaw. Once thawed, gently pat them dry with a clean kitchen towel or paper towels. Removing excess moisture helps the casserole bake up creamy rather than watery.
3. Sauté the onion. Place a large skillet over medium heat and add 2 tablespoons of unsalted butter. When the butter is melted and starting to sizzle, add the diced yellow onion. Cook, stirring occasionally, for about 4–5 minutes, until the onion is soft and translucent.
4. Add the garlic. Stir the minced garlic into the skillet with the onion and cook for another 30–60 seconds, just until fragrant. Take care not to brown the garlic. Remove the skillet from the heat and set it aside.
5. Make the creamy base. In a large mixing bowl, combine the sour cream, condensed cream of mushroom soup, and whole milk. Whisk or stir until the mixture is smooth and fully blended, with no streaks of soup or sour cream.
6. Season the sauce. Add the kosher salt, black pepper, smoked paprika, dried thyme, and Worcestershire sauce to the bowl. Stir well so the seasonings are evenly distributed throughout the creamy mixture.
7. Stir in the cheese. Add 2 cups of the shredded sharp cheddar cheese to the bowl, reserving the remaining 0.5 cup for the topping. Fold the cheese into the sauce until it is evenly mixed.
8. Fold in the hash browns. Add the thawed and dried shredded hash browns to the bowl with the creamy cheese mixture. Gently fold everything together until all of the potatoes are coated and there are no dry pockets.
9. Add the brisket and parsley. Add the cooked shredded brisket and half of the chopped fresh parsley to the bowl. Fold gently until the brisket and parsley are evenly distributed throughout the potato mixture, being careful not to overmix.
10. Transfer to the baking dish. Spoon the brisket and hashbrown mixture into the prepared 9x13-inch baking dish. Use a spatula to spread it into an even layer, smoothing the top so it bakes uniformly.
11. Prepare the topping. In a small bowl, combine the panko breadcrumbs, olive oil, melted butter for topping, and the remaining 0.5 cup shredded sharp cheddar cheese. Toss with a fork until the panko is evenly coated and starts to clump lightly with the cheese.
12. Top the casserole. Sprinkle the breadcrumb and cheese mixture evenly over the surface of the casserole, covering it from corner to corner. This will bake into a crisp, golden crust.
13. Bake until bubbly and golden. Place the baking dish on the center rack of the preheated oven. Bake for 35–45 minutes, or until the casserole is hot and bubbling around the edges and the topping is nicely golden brown.
14. Let it rest. Remove the casserole from the oven and set it on a heatproof surface. Allow it to rest for 10–15 minutes. This short resting time helps the creamy layers set, making it easier to slice and serve.
15. Garnish and serve. Sprinkle the remaining chopped fresh parsley over the top for a pop of color and freshness. Slice or scoop the brisket hashbrown casserole into portions and serve warm, enjoying the tender brisket, creamy potatoes, and crispy cheesy topping together in every bite.

Common Questions About Brisket Hashbrown Casserole

Can I make this casserole ahead of time?

Yes. You can assemble the brisket hashbrown casserole through the step where you spread the mixture in the baking dish and add the topping. Cover it tightly and refrigerate for several hours or overnight.

Can I freeze leftovers of this casserole?
