The best roast beef sandwich recipe

Cold cut sandwiches tend to be boring and lack flavor, but this isn't your average cold cut sandwich. This homemade roast beef sandwich puts regular old sandwiches to shame. 

That's because we'll be putting together several delicious components, and layering this sandwich with ingredients to create a delicious combination of flavors.

And the garlic aioli recipe incorporated into this sandwich, along with the caramelized onions, tie everything together giving you a flavor that you can't even get at the deli.

Now let's check out what makes this roast beef sandwich so delicious.

 Ingredients

So, the recipe we're making today is comprised of three different components - the caramelized onions, the garlic aioli, and then everything else that completes the sandwich.

That said, here's what you'll need to make the caramelized onions:

• 1 onion (yellow, white, or red)
• ⅔ cup apple cider vinegar
• 5-6 tbsp. brown sugar

For the garlic aioli:

• ⅓ cup mayonnaise
• 1 small clove of garlic, minced
• 1 teaspoon of freshly squeezed lemon juice 

And to complete the sandwich:

• 4 brioche hamburger buns
• ½ pound of thickly sliced roast beef (you can use more if you prefer a thicker sandwich) 
• 4 ounces sliced provolone
• Green leaf lettuce
• Sliced tomato
• Small cucumber, sliced
• Microgreens for a garnish

Of course, feel free to leave out any ingredients that you may not like, or substitute them with an ingredient of your choice.

You can really customize this sandwich however you want, just like with these shrimp burgers!

TYPES OF BREAD TO USE 

So, there are an endless amount of bread options for you to choose from when it comes to this sandwich.

And you can pick a new bread every time, giving you a completely different experience.

Brioche Roast Beef Sandwich

With that said, my favorite bread to use for this roast beef sandwich recipe is a brioche hamburger bun. The soft brioche bun adds a nice buttery flavor to the sandwich, and it crisps up perfectly too.

Ciabatta Roast Beef

Now, if you prefer a harder roll, you can use ciabatta bread, which has a more chewy texture - by the way, this is a great ciabatta bread recipe. And you can also turn this recipe into a roast beef sub just by using a hard or soft submarine roll. 

Low Carb Roast Beef

Lastly, to lower the carb count of this recipe and turn it into a low carb sandwich, you can have it on this low carb bun, or this 2-minute keto bread. 

And of course, if you don't have any of these options, you can use whatever bread you have at home. Your roast beef sandwich will still turn out quite tasty.

CHEESE OPTIONS

Along with the bread, cheese is another component of a complete sandwich. And of course, there are countless cheeses you can choose from for this sandwich. 

That said, I prefer to use provolone cheese because I like how the mild, flavor compliments the other ingredients, instead of overpowering them. 

But, if you want a sharper cheese taste to your sandwich, try using cheddar or Swiss. 

And for a smokey flavor with a stronger taste, use smoked gouda or gruyere

Lastly, to give your sandwich a spicy kick, you can use pepper jack cheese.

The options are practically endless - so try experimenting with different types of cheese until you find which one you like best! 

How to Make A Roast Beef Sandwich

Ok, so we went over the ingredients you need to make this roast beef sandwich - and we talked about some alternatives as well - now it's time to go over how to make it.

And, as I mentioned earlier, there are only a few simple steps you need to follow - so, let's get to it!

Step 1: Caramelizing the Onions

The first thing you will want to do is peel your onion and cut it into relatively thin slices. 

Then, heat a skillet over medium-high heat with enough olive oil to cover the entire surface of it. And 2 minutes is all that you should need to heat it for.

Once your skillet is hot, add your onions to it and spread them out evenly, then cook them until they are soft and golden brown. 

Then, when the onions are cooked, add your apple cider vinegar and the brown sugar, and stir everything together until the mixture thickens.

Step 2: Making the Garlic Aioli 

To make the garlic aioli, crush the garlic cloves with the flat side of a knife, remove the skin, and finely mince.

Then, using the flat of a knife again, you can scrape and press the garlic against the cutting surface to make a paste that's as smooth as possible. 

Now, once you've created that garlic paste, add it to a small bowl, and whisk it together with the mayonnaise and lemon juice.

Then, when it is fully combined, cover the aioli with plastic wrap and refrigerate for about 30 minutes.

Step 3: Making the Sandwich

So, assembling this roast beef sandwich is just about as easy as assembling any other kind of sandwich.

Having said that, if you're making a cold roast beef sandwich, just spread the garlic aioli on both sides of your bun, and put all of the fixings on it in any order you want.

Making a Hot Roast Beef Sandwich

Ok, so, you'll need to follow a few extra steps to make a hot roast beef sandwich.

First set your oven to broil, and then spread the garlic aioli on both sides of the bun. Then, top each half with roast beef, onions, and cheese. 

Now, place the sandwich halves on a cookie sheet, and broil 3 inches away from the heat for 2-3 minutes - or until the cheese is melted. 

So, once that cheese melts, take your hot roast beef sandwich out of the oven, and top it with the fixings of your choice!

STORING YOUR LEFTOVERS

The ingredients you'll need to make this roast beef sandwich refrigerate incredibly well.

Fresh roast beef from the deli will last in the refrigerator for up to 5 days, and the caramelized onions will last for up to 4 days in an airtight container.

And the garlic aioli will last in the refrigerator in an airtight container for up to 10 days.

So you can enjoy a few sandwiches throughout the week!
