Beef Tenderloin Crostini

This is medium-rare, spice-crusted filet mignon, cut into slabs and placed on a toasted baguette with creamy horseradish Sauce and Blue Cheese crumbles.

And this is a real guy type of appetizer, so serve it in the oven tray that the baguette is toasted in.

We’re not looking for fancy here, just a very good beef tenderloin Steak appetizer.

It’s something you can make in the first half of the game and serve during the halftime show.

Just allow for 15 minutes of Cooking and 10 minutes of resting time.

Prep everything ahead of time, and you can pick and choose when you are busy in the kitchen. This is pretty versatile.

Dry Rub for Beef Tenderloin Crostini

Keeping it simple, I used salt, pepper, granulated Garlic, and oregano for the dry rub.

This gives the beef’s Crust a burst of flavor. The recipe ingredients are enough for a 7 or 8-ounce filet.

First, take the Meat out of the refrigerator 30 to 60 minutes before searing. 

Lightly coat the filet with canola oil and then press all of the Dry Rub onto the surfaces of the filet.

Pan-Searing the Tenderloin Filet

The tenderloin should be seared in a heavy skillet and I recommend cast iron.

A non-stick skillet is not good for this amount of heat and it would probably get damaged by the high heat.

Place a tablespoon of canola oil in the skillet and bring the oil to smoking on high heat.

My infrared temperature gun had the temp at 450°F.

Try to keep the temperature at no more than this. I have an electric stove, so I raise the skillet off the element to let it cool a little if it’s too hot. I try to aim for 425° to 440°F.

A laser temperature gun (#ad), is a good tool to have for this.

Place the filet into the skillet on the edge to brown the sides of the Meat.

Let the meat sear for a minute, then turn to another edge. Keep working around the filet to brown.

Turn the meat to the top side to sear. Let this go for a couple of minutes, then turn to the opposite side.

Turn the heat down and flip the meat every couple of minutes until the internal temperature is around 130° for medium-rare. 

Beef Cooking Temperatures

Here are the recommended temperatures for the amount of doneness of the beef.

Rare – 125°

Medium-rare – 135°

Medium – 145°

Medium-well – 150°

Well done – 160°

When cooking the beef you would remove the meat from the heat 5 degrees less than the finished temperature.

Rest the beef by tenting it with aluminum foil and while it rests, the temperature will rise around 5 degrees.

With experience, you can judge the Perfect doneness of a filet with your fingers.

Place a finger on the meat and see how much the meat jiggles with movement.

If it seems like the meat is a water-filled balloon, it has to cook some more. 

If the meat doesn’t jiggle but is soft, the Temperature is probably good for medium-rare. It’s best to use an instant-read thermometer though. 

Remove the filet from the skillet and tent it with foil for 10 minutes before slicing.

Toast the Baguette

Turn on your oven broiler to high and place a rack 6 or 7 inches away from the element.

Slice the baguette into 1/4 inch slices and place on a baking sheet. 

Drizzle the bread with olive oil, then spread the oil with a brush. Sprinkle the bread with a bit of kosher salt and granulated garlic, (or garlic salt).

Place the sheet into the broiler for 1 to 1 1/2 minutes, turning the sheet occasionally to brown evenly.

This is where you have to really babysit the bread so it doesn’t burn. That can happen fast if you are not careful.

Assemble your Beef Tenderloin Appetizer

After the filet has rested, cut it into 1/4″ pieces using a sharp knife.

Keep the toasted baguettes on the baking sheet and spoon some horseradish sauce onto each piece.

Use a good amount of the sauce because it is so tasty. 

Lay a Medium Rare Filet slice on the horseradish sauce, then use a spoon to sprinkle crumbles of blue cheese onto the beef appetizer. 

Finish by sprinkling on a little chopped parsley and serving on the Baking Sheet with extra blue cheese. There is no need to plate the tenderloin toasts. They will get gobbled up, as will the extra blue cheese.

By the time the filet mignon crostini is served, it is most likely room temperature, and that makes no difference. It tastes amazing.

This Tenderloin Recipe is so tasty that you may want to serve it as a Main Course meal. Serve it with a side salad and a nice Red Wine. 

Frequently Asked Questions

Slice the beef thinly against the grain to ensure tenderness and ease of eating.

Beef tenderloin is ideal due to its tenderness and flavor. It’s perfect for quick searing and pairs well with various toppings.

Ingredients

  • 1 7 or 8 oz. beef tenderloin, (filet mignon)

Beef Dry Rub

  • 1 tsp kosher salt
  • 1/2 tsp black pepper, fresh coarse ground is best
  • 1/2 tsp granulated garlic
  • 1/2 tsp dried oregano

Horseradish sauce

  • 1 or 2 tbsp fresh ground horseradish, Silver Springs Foods brand or similar, see notes Not creamy prepared
  • 1/4 cup sour cream
  • 1 tsp dijon mustard
  • pinch of salt

All other ingredients

  • 2 tbsp canola oil, divided

  • granulated garlic, for the baguette
  • Chopped parsley for garnish

Instructions

  • Take the filet out of the refrigerator 30 to 60 minutes before cooking.
  • Mix the horseradish sauce ingredients in a small bowl and set aside.
  • Mix together the dry rub ingredients. Apply a light coating of canola oil on the filet and sprinkle the dry rub on all sides of the meat.
  • Using a cast iron or heavy stainless steel skillet, add 1 tablespoon of canola oil and place on high heat. Once the oil is smoking, start searing the beef starting with the sides. Lower the heat and try to maintain about 440°F. Sear each side for around 90 seconds to get some nice browning. Keep turning the meat to the remaining sides. Once the sides are browned, turn the meat to the first end and sear about 90 seconds, then turn to the final un-browned end. Keep rotating the meat with tongs until the internal temperature is 130° when measured with an instant read thermometer. This will take 8 to 12 minutes depending on the temperature of the skillet. Remove the filet from the heat and rest for 10 minutes tented with foil. Then slice into 1/4" pieces.
  • Turn on your broiler on high and place the rack 6 to 7 inches from the heating element or flame. Place the sliced baguette onto a small, sided baking sheet and drizzle with olive oil then brush to coat. Next sprinkle the bread with a very small amount of kosher salt and granulated garlic. Place the sheet under the broiler to toast the bread, turning every 30 seconds or so to brown evenly. Keep a close eye on this and remove the pan from the oven when slightly toasted, 1 1/2 to 2 minutes.
  • Keep the toasted baguettes in the baking sheet and spoon the horseradish sauce on each slice. Place a slice of filet on each, then sprinkle with crumbled blue cheese. Garnish with chopped parsley. Serve warm or at room temperature.

Notes

  1. For the horseradish sauce, start with 1 tablespoon of horseradish and taste. If you would like more heat add up to 1 more tablespoon.
  2. If you have a favorite brand of creamy prepared horseradish you could use it rather than making my sauce.
  3. Without an infrared thermometer it is hard to know the temperature of your skillet. The meat will start really smoking if it's too hot. It might be best to turn the heat down after the initial sear to finish cooking. And you don't want your smoke alarm going off either.
