Open Faced Roast Beef Sandwich Recipe – Using the Slow Cooker!

I. LOVE. MY. SLOW. COOKER.

There's just nothing better than waking up in the morning with a plan of attack for the day . . . (well, at least a plan for dinner) . . . . and knowing that my cooking is just about finished up by 8 AM.

This recipe for open faced roast beef sandwiches is seriously some good stuff. It's made with a sirloin tip roast and a yummy marinade. Your family will love this!

Just make sure to stick your meat and marinade in the fridge the night before you make it, so it'll be all set to dump in the crockpot in the morning.

How to make the BEST Hot Open Faced Roast Beef Sandwich:

Start by mixing together teriyaki or soy sauce, beef broth, vegetable oil, onion, garlic, brown sugar, Worcestershire, and hot pepper sauce.

Next, place your roast in a large zip-top bag, pour the marinade over the top and refrigerate at least overnight. The longer the better!

In the morning, place the roast and the marinade in your slow cooker. Cover and cook on low 7-8 hours. When the meat is done, shred meat and return to slow cooker and mix in with all the remaining liquids.

Toast bread and place on a baking sheet; layer shredded beef and cheese on top of toasted bread. Then broil in oven 2-3 minutes, or until cheese is lightly browned.

You can use a store bought Italian loaf bread here but consider making my homemade bread for these sandwiches. It's soooo yummy and worth the extra few minutes. 🙂

What is the best cut of beef to use in this recipe?

A sirloin tip roast is perfect, but if you can't find one a shoulder roast or even a chuck roast will work as well.

What toppings are good on a hot sirloin sandwich?

Melted gooey Provolone cheese is my favorite on these open faced sirloin steak sandwiches! If you're feeling adventurous, sauté some onions until they are caramelized and add those to your sandwich ~ this is just divine. Mustard and mayo (either one) are great, as well as pickles if those are your thing.

What sides go well with roast beef sandwiches?

I'm always a fan of a good side salad but a few other ideas are:

• baked potatoes
• grilled veggies
• broccoli salad
• sweet potato fries

This is a wonderful recipe for the beginner or the most experienced cook. You'll for sure want to add these sirloin steak sandwiches to your menu rotation. 🙂
