Importance of Each Tool

Ingredients

For the Sandwiches

8 slices Toast
600 grams Roast beef
salt
freshly ground peppers
1 Tbsp Mustard
4 Tbsps vegetable oil
2 onions
1 handful Lettuce (such as arugula and spinach)

How to Make Roast Beef Sandwiches with Lettuce and Onions

Step 1: Sear the Roast Beef

Rinse the roast beef under cold water and pat it dry with paper towels.
Season generously with salt and freshly ground pepper.
Heat 2 tablespoons of vegetable oil in a frying pan over medium-high heat.
Sear the roast beef until golden brown on all sides.

Step 2: Roast the Beef

Remove the seared roast from the pan and brush it with mustard.
Transfer it to a rack set over a roasting pan.
Preheat your oven to 140°C (approximately 275°F).
Roast the beef in the oven for about 30 minutes.

Step 3: Prepare the Onions

Peel the onions and cut them into rings.
In the same frying pan used for searing, add any remaining oil if needed.
Sweat the onion rings over medium heat until they are golden brown, stirring occasionally.
Season with salt and pepper.

Step 4: Assemble Your Sandwiches

Rinse the lettuce, pat it dry, and chop it coarsely.
Toast your bread slices until golden brown.
Once the roast is done resting (about 5 minutes), slice it thinly.
On four slices of toast, layer thin slices of roast beef, sprinkle with salt and pepper, add caramelized onions, then top with lettuce.
Finish by placing another slice of toast on top of each sandwich. Cut each sandwich in half diagonally before serving.

Common Mistakes to Avoid

When making Roast Beef Sandwiches with Lettuce and Onions, a few common mistakes can impact your dish’s flavor and texture. Here are some tips to keep in mind.

Skipping seasoning: Failing to season the roast beef properly can lead to bland sandwiches. Always season generously with salt and pepper before cooking.
Overcooking the beef: Cooking the roast beef for too long will make it tough and dry. Use a meat thermometer and aim for medium-rare for the best results.
Slicing too thick: Cutting the roast beef into thick slices can make it hard to eat. Aim for thin, even slices for ideal texture and flavor integration.
Neglecting freshness: Using wilted lettuce or stale bread will negatively affect your sandwich. Always use fresh ingredients for maximum crunch and taste.
Ignoring resting time: Cutting into the roast immediately after cooking can result in juices spilling out. Let it rest for at least 5 minutes before slicing.

Refrigerator Storage

Store leftover sandwiches in an airtight container.
Keep them in the fridge for up to 3 days.

Freezing Roast Beef Sandwiches with Lettuce and Onions

Wrap each sandwich tightly in plastic wrap or aluminum foil.
