  • Onion: Chopped and cooked with the pot roast, this ingredient will add a sweet and savory touch to your hash.
  • Salt and Pepper: Simple but essential seasonings to enhance the flavors in your dish.
  • Flour: This will be used to thicken the sauce in your hash and create a rich and creamy texture. You can also use cornstarch if you don’t have any flour or want to keep it gluten-free!
  • Water: To help dissolve the flour and make a slurry so it can be added to the beef hash.
  • Biscuits: Warm, flaky biscuits are the perfect base for this dish. Whether you make them from scratch or use store-bought ones, they will add a touch of buttery goodness to every bite.
  • Diced Veggies: This is optional but can add some extra flavor and texture to your hash. You can use carrots, celery, bell peppers, or any other veggies you have on hand. I use the ones leftover from making my pot roast.

Tips for making roast beef hash

Making beef hash with leftover pot roast is a great way to repurpose your leftovers and create a delicious and hearty meal. Here are some tips to help you make the best pot roast hash:

  1. Use leftover pot roast: The key ingredient in this dish is the leftover pot roast. It’s already been cooked and seasoned, making it perfect for creating a flavorful hash.
  2. Dice the meat: Make sure to dice the pot roast into small, bite-sized pieces. This will ensure that the beef is evenly distributed throughout the hash and makes it easier to eat.
  3. Add diced vegetables: If you have any leftover roasted vegetables, such as carrots or potatoes, feel free to add them in for extra flavor and texture.
  4. Season to taste: The pot roast has already been seasoned, but feel free to add in any additional salt or pepper to adjust the flavor to your liking.
  5. Use a pan, not microwave: While it may be tempting to just throw the leftover pot roast in the microwave, taking the time to cook it in a pan will result in a better texture and flavor for your hash.

What to serve with beef hash

Whenever I plan on making some leftover pot roast hash, I always make sure to grab some of my favorite biscuits. Freshly baked and warm out of the oven, they are the perfect accompaniment to this hearty dish.

I like to keep some frozen in my freezer for recipes like this! All you have to do is pop them in the oven while you prepare your hash, and they will be ready in no time.

If you don’t have any biscuits, you can also use some warm yeast rolls or some homemade cornbread!

You can also serve the beef hash over rice or with a side of steamed vegetables for a well-rounded meal.
