Why You’ll Love This Recipe
This isn’t just another roast beef sandwich recipe; it’s a special treat for your taste buds! The combination of tender slices of beef, homemade garlic aioli, and buttery lettuce makes every bite pure perfection. Plus, it’s a versatile, no-fuss recipe that transforms leftover roast beef into a completely new meal.
In my opinion, a good roast beef sandwich starts with the most amazing beef roast. Use this easy sirloin tip roast beef recipe to make a roast that you can later cut into slices.
Alternately, you can go to the deli counter and ask for their best cut of meat. Have the butcher cut it into thick slices to use in this recipe. The thicker cut of meat adds to the rich flavor of this sandwich.
Next, you’ll want to make a quick sauce to pair with the roast beef. We love this roasted garlic aioli recipe. It’s really what makes this sandwich so delicious and flavorful.
We have some variations and suggestions at the bottom of the post, if you don’t have time to make the sauce. But we highly recommend that you do! It’s super easy and totally worth it.
