Ingredients
Below are the essential components of this homemade roast beef sandwich recipe. Find some yummy roast beef at your local deli or the deli department in the grocery store.
- Buns: I use sesame seed buns for this recipe. However, you can get creative with it. Make a tasty sub using this Italian herb and cheese bread, for example.
- Roast beef: Thinly sliced beef just tastes better and has a better texture. It's way more tender as well, which makes each bite perfect.
- Toppings: I chose lettuce, tomato, and caramelized onions. You can use any or all of these toppings for your sandwich. Raw red onions and pickles are delicious, too.
- Cheese: In my opinion, the best cheese for a roast beef sandwich is sharp cheddar. However, you can choose any that you like. Provolone and Swiss also pair well with the beef.
- Honey mustard mayonnaise: This is a homemade spread that I think pairs well with the roast beef. It consists of honey, Dijon mustard, and mayonnaise. You can even try making this sauce with yellow mustard if you like.

- Italian-style: Use an Italian-style roast beef, provolone or mozzarella cheese, and this garlic mayo to spread on the buns.

Recipe Tips
- Use good-quality roast beef: Don't skimp on the roast beef, as it's the most important component of the sandwich! Choose one of good quality, but it doesn't have to be super expensive.
- Pat the veggies dry: To prevent the sandwich from becoming too wet or soggy, gently pat the lettuce dry after washing it, and the tomatoes to minimize dripping.
- Toast the buns: I recommend toasting the buns if you can. It adds texture and helps create a barrier to prevent the condiments from soaking through.
- Storing: You may keep extra sandwiches in the refrigerator for 1-2 days, but I don't recommend freezing them, as it will make the bread soggy when they thaw.
