5-Ingredient Boursin & Roast Beef Crostini

These boursin and roast beef crostini are a stunning (but uber easy), no-cook appetizer. They’re piled with tender roast beef, peppery arugula, and a sprinkling of fresh chives. But the real key here is the herby boursin cheese which adds so much flavor with no extra work. Make sure to bring these to your next holiday party or get together with friends!

Hi friends! I’m just sneaking in with one last holiday appetizer recipe before I officially hit snooze on working for the next few days to watch movies, finish out my Christmas cookie stash, and sip champagne.

So, if you need a nice little appetizer on your hands for New Year’s and any upcoming get-togethers, let me introduce you to this crostini! All you need is 5 ingredients and about 10 minutes to whip it up. Add another 5 minutes if you decide to make homemade boursin cheese instead of store-bought.

This appetizer is inspired by these roast beef sandwiches that I used to make in culinary school. We replaced the mayo with boursin cheese and it was ridiculously good. So I’m crostini-fying it!

Once you have a crispy, crunchy batch of homemade crostini, the rest comes together pretty easily. Swipe some boursin over each cracker, add a small pile of arugula and roast beef, and top everything off with fresh chives. And there you have it. A quick-and-easy app that comes together in minutes.

Also, if you’re looking for more easy beef appetizers, I have plenty! Start with these blue cheese and steak crostini or for a super elegant option, beef Wellington bites. For something on the gooier end of the spectrum, you also can’t go wrong with Philly cheesesteak sliders!

Pick a good roast beef

Like I said, you only need a few basic ingredients here. But since this recipe simple, high-quality ingredients are important. Especially the roast beef! I 1,000% recommend getting the good stuff from the deli. And thinner sliced is better for easy piling.

You’ll also need either store-bought or homemade crostini. I like homemade cause it’s just so easy but store-bought is totally fine in a pinch. You’ll also need boursin cheese, peppery arugula (or whatever greens you like), and fresh chives.

3 easy steps

I like to serve the crostini at room temperature cause it brings out all of the best flavors in the cheese. Just make them about 30 minutes before you’re ready to serve!

Roll the roast beef

To keep the meat from slipping off the toasts, make sure you get thinly-sliced roast beef! I like to buy it from the deli counter so it’s as fresh as possible. Then, you’ll want to roll the beef or fold it into ribbons and place it seam-side down. This will help the beef stay on top!

Make the crostini in advance

Since this recipe doesn’t have any sauces, it holds up better than other crostini I’ve made. You can make the crostini a few hours before your party! Just cover the tray and refrigerate them for up to 3-4 hours. Make sure to take them out about 30 minutes before eating so they come to room temp.

Refrigerate leftovers

If you have any leftovers, you can store them for up to 2 days. Place the crostini in an airtight container, cover, and refrigerate.

Keep in mind that the crostini may get soggier as they sit in the fridge! If you want them as fresh as possible, I’d prep all the ingredients and make them right before serving.

If you make this recipe, I would love it if you left a star rating and review! I read every single comment and love hearing what you think about my recipes. Thank you for supporting Sunday Table!
