When you think of po boy sandwiches, your mind probably goes to a shrimp po boy, but roast beef po boy sandwiches are just as common, and probably easier to make at home! Here’s our take on how to make a delicious roast beef po boy sandwich at home that brings authentic New Orleans flavor to your kitchen.

Po Boy sandwiches are a staple of Louisiana cooking. We’d like to call them a Cajun take on a submarine sandwich, but that’s doing them a little bit of an injustice. These sandwiches are dripping with juicy gravy and have the perfect combination of ingredients to bring a balanced flavor to the dish, just like all Cajun cooking.

You can make po boys with fried shrimp, oysters, catfish, or crab, but as a butcher shop, we’re here for the roast beef po boy. We’re making this sandwich as simple as possible by starting with deli roast beef and using a beef gravy packet for the sauce.

If you want, you can definitely make your own roast beef and then make a gravy from the drippings, but we want our roast beef po boy recipe to be as simple, fast, and easy as possible. If you’re looking for a more involved recipe, check out this Roast Beef Po Boy recipe from one of New Orleans’ most famous chefs – Emril Lagasse!

What type of beef should I use for my roast beef po boy?

We recommend starting with thinly sliced roast beef from your favorite deli – hopefully that’s our deli here at Lake Geneva Country Meats! You can certainly make your own roast beef (see below), but you can save time and get a really great product by buying already roasted roast beef.

We sell Boar’s Head London Broil Roast Beef, which in our opinion is perfectly seasoned and cooked for this sandwich. Remember, you can’t have a great sandwich without great ingredients, so don’t skimp on the roast beef.

Can I make my own beef for this sandwich?

Of course you can! If you want to really make a roast beef po boy sandwich from scratch, follow these instructions to make your own roast beef at home:

  1. Season a 1.5# beef top round roast with salt and pepper, and then sear all sides in 2 tbsp. of vegetable oil inside a Dutch oven.
  2. Once seared, remove the beef and set aside. Add 1 chopped onion, 2 stalks of chopped celery, and 2 cloves of minced garlic to the pot and cook over medium heat until softened.
  3. Add the beef back in, along with 4 cups of chicken broth and 2 bay leaves.
  4. Bring the mixture to a boil, cover the Dutch oven, and let cook at a simmer for about 2 hours, until the beef is fork tender.
  5. Once the beef is fork tender, remove from the pot and place in refrigerator for at least two hours.
  6. Once chilled, slice the beef into thin slices and use for this recipe.

Can I make this a spicy roast beef po boy sandwich?

Of course you can! The easiest way to make this spicy is to spice up the mayonnaise. To do so, add 1 tablespoon of hot sauce such as Tabasco to your favorite mayonnaise and mix together. Taste and add more hot sauce as you’d like. You can also purchase spicy mayonnaise or mustard to use, if you like!

What should I serve with my roast beef po boy sandwich?

Whatever you would normally serve on the side of a sandwich is great with your roast beef po boy, but here are some suggestions on sides:

  • Cajun-seasoned potato chips
  • French fries seasoned with Cajun seasoning
  • Fried pickles
  • Mac & Cheese
  • Nothing, because this is a super filling and delicious sandwich all by itself 🙂

We hope you like this very simple, and very delicious roast beef po boy sandwich recipe. We’re not trying to create the most perfect sandwich, just one that is yummy and easy to get out for a meal.
