Introduction

Ingredients
- 2 pounds beef roast (chuck or round works well)
- 1 medium onion, sliced
- 2 cups beef broth
- 2 tablespoons Worcestershire sauce
- 1 tablespoon soy sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme
- 1 teaspoon black pepper
- 1/2 teaspoon salt
- 2 tablespoons cornstarch + 2 tablespoons cold water (for slurry)
- 6 slices of bread (white or Texas toast style)
- 4 cups mashed potatoes (homemade or prepared)
Instructions
- Step 1: Place the sliced onion in the bottom of your slow cooker. Lay the beef roast on top of the onions.
- Step 2: Pour in the beef broth, Worcestershire sauce, and soy sauce over the beef.
- Step 3: Sprinkle garlic powder, onion powder, thyme, black pepper, and salt evenly over the beef.
- Step 4: Cover and cook on LOW for 8 hours or HIGH for 4–5 hours, until the beef is tender and easy to shred.
- Step 5: Remove beef from the slow cooker and shred it with two forks.
- Step 6: Strain out the onions and return the broth to the pot. Stir in the cornstarch slurry (2 tablespoons cornstarch mixed with 2 tablespoons cold water) and cook a few minutes until the gravy thickens.
- Step 7: To serve, place a slice of bread on a plate, top with mashed potatoes, add shredded beef, and ladle the hot gravy generously over the top.
Tips & Variations
- For extra flavor, sear the beef roast in a hot pan before placing it in the slow cooker.
- Use leftover mashed potatoes or instant mashed potatoes for a quicker version.
- Try topping with sautéed mushrooms or caramelized onions for added richness.
- Texas toast adds a nice buttery crunch, but any sturdy white bread works well.
Storage
Store leftover beef and gravy in an airtight container in the refrigerator for up to 3 days. Bread and mashed potatoes are best prepared fresh but can be refrigerated separately for the same time. Reheat beef and gravy gently on the stove or in the microwave, stirring occasionally to maintain moisture.

FAQs
Can I use a different cut of beef for this recipe?
Yes, chuck and round are ideal because they become tender when slow-cooked, but you can also use brisket or other roasts suitable for slow cooking.
How do I prevent the bread from getting soggy?
Serve the dish immediately after assembling, and use sturdy bread like Texas toast. Toasting the bread lightly can also help it hold up better under the mashed potatoes and gravy.
