Beef Tenderloin Sliders

These beef tenderloin sliders are a delicious and elegant appetizer for a party or gathering that is sure to impress even the most picky guests.

The first time I made these Beef Tenderloin Sliders it was for a Super Bowl party. They were such a big hit that they have become a favorite for any special occasion or get together. The key to this is the beef tenderloin.

I choose to cook mine by sous vide method. Sous vide cooking is a great way to ensure that the beef cooks to the perfect temperature all the way through. Detailed cooking instructions and all you need to know about sous vide cooking are here in our Sous Vide Beef Tenderloin post. Check it out, sous vide cooking is too good to miss out on!

Once the tenderloin is finished in the sous vide, just finish it with a quick hit on the grill to give it that nice char. Slice it up and it’s ready for the sandwiches.

If you don’t have a sous vide, using the grill or oven is perfectly fine. For either of these methods, I simply use salt and pepper and then cook at a low temperature. In the oven, I go for 200 degrees for about 1 hour for a 2lb. tenderloin or until a thermometer inserted in the middle reads 130 degrees for medium rare.

On the grill, I cook over indirect heat for 45-60 minutes, or again, until it reaches an internal temperature of 130 degrees for medium rare.

Once the beef is done, let it rest for at least 10 minutes. Carve it into thin slices and it is ready for when you build the sliders.

Building the sliders

There are many options for building these sliders and it really depends on your preferences, but we think this is the perfect tenderloin slider: Arugula (adds a great peppery flavor) or spinach, caramelized onions, blue cheese and horseradish sauce. As with anything, quality of the ingredients does matter, so choose what is fresh and looks the best.

First, toast the buns in the broiler. Next, slather some of the horseradish sauce on the bottom of the bun. Add the caramelized onions, one or two slices of tenderloin and top with the arugula and blue cheese crumbles. Voila, you have the best beef tenderloin slider!

Beef Tenderloin Sliders-Ingredients

• 2 lbs beef tenderloin
• 2-3 vidalia onions (medium)
• 1-2 tbsp olive oil
• 1 bag of arugula
• 1 package blue cheese crumbles
• 1 package slider rolls

Beef Tenderloin Sliders-Instructions

• Salt and pepper the tenderloin. 
• Cook tenderloin via, sous vide, oven or grilling methods. 
  • Sous Vide Cooking: Fill a pot or sous vide container with water and attach the immersion circulator. Set the temperature for 130-135 for medium rare, 135-140 degrees for medium, and 145-155 for medium well. Once water is up to desired temperature, add the prepared tenderloin to the bag and squeeze the air out of the bag. Slowly lower the bag into the water allowing any air to escape, then zip the bag. Cook for 2-3 hours at desired temperature. Once desire temperature is reached, remove the tenderloin from the bag, pat dry with a paper towel and lightly salt. Place on a hot grill for 30-45 seconds per side to get a nice char. 
  • Oven Cooking: Place prepared tenderloin in a roasting pan. Cook tenderloin in a preheated oven set to 200 degrees for about an hour or until a thermometer inserted in the middle reaches the desired internal temperature. 
  • Grill Cooking: Cook over indirect heat for 45-60 minutes, or again, until it reaches the desired internal temperature. 
  • Once tenderloin is done, let rest for 10 minutes before carving. 
• While the tenderloin is cooking slice the onions. Add oil to a sauté pan. Over medium heat, cook onions until caramelized, stirring occasionally for about 30 minutes. Set aside.

Horseradish Sauce

• Mix together sour cream, horseradish, dijon mustard, lemon juice and salt. Set aside.
