Step-by-step: How to make Grilled Beef Tenderloin Crostini with Béarnaise Sauce

1. Prep the crostini:

   • Preheat your oven to 375°F (190°C). Brush baguette slices lightly with 2 tbsp olive oil, sprinkle with a pinch of salt and pepper. Toast for 8–10 minutes until golden and crisp. Set aside. If you prefer the charred flavor, grill them quickly on a hot grill pan for 30–60 seconds per side.

2. Season the beef:

   • Rub the tenderloin with 1 tbsp olive oil, garlic powder, salt, and black pepper. Bring it to room temperature for about 15 minutes; this helps it cook evenly.

3. Sear and grill the tenderloin:

   • Heat an ovenproof skillet (cast iron is perfect) over medium-high heat. Sear the tenderloin on all sides until browned, about 2 minutes per side.
   • Transfer to a 400°F (205°C) oven for 8–12 minutes for medium-rare depending on thickness (use a meat thermometer: 125–130°F for medium-rare). Tent with foil and let rest 10 minutes. Resting is non-negotiable — it keeps the meat juicy.

4. Make the Béarnaise sauce (stovetop method):

   • In a small saucepan, combine white wine vinegar, white wine (or water), shallots, and half the tarragon. Simmer until reduced by about half, then strain into a heatproof bowl. Cool slightly.
   • Whisk egg yolks into the reduction. Place the bowl over (not touching) simmering water (double boiler). Whisk constantly until thickened and pale.
   • Slowly drizzle in the warm melted butter while whisking vigorously. Finish with salt, cayenne, and the remaining chopped tarragon. If the sauce gets too thick, whisk in a teaspoon of warm water to loosen it. If it breaks, use a clean bowl and whisk in a tablespoon of warm water, then slowly whisk the broken sauce back in.

   Tip: If you’re nervous about making Béarnaise, you can use hollandaise as a fallback or try a reliable blender method (blend egg yolks and reduction, slowly add warm butter with the blender running). Béarnaise is worth trying once — it tastes like springtime butter.

5. Slice and assemble:

   • Thinly slice the rested tenderloin against the grain (think thin, elegant slices).
   • If using, spread a small smear of goat cheese or ricotta on each crostini. Top with a slice of beef and a generous dollop of Béarnaise. Garnish with microgreens or tarragon.

6. Serve immediately:

   • These are best fresh — warm crostini, room-temp or slightly warm beef, and silky Béarnaise. Arrange on a platter and watch them disappear.

Practical tips and tricks (because life happens)

• Don’t overcook the meat. Use a thermometer. No thermometer? Aim for slightly underdone when you pull it — it will carry over cook while resting.
• Béarnaise can be done ahead and kept warm in a thermos or over a bowl of warm water for an hour. Reheat gently; don’t blast it with heat.
• If your Béarnaise looks a bit grainy, whisk in a teaspoon of warm water or a squeeze of lemon to bring it back.
• For a shortcut, swap in a high-quality store hollandaise and stir in fresh tarragon for a Béarnaise-ish flavor when you’re short on time.
• Make crostini ahead: Toast and store in an airtight container. Assemble just before serving so they stay crisp.

A short story from my kitchen
The first time I made this for guests, my nephew — age nine and suspicious of anything that wasn’t chicken nuggets — took one bite, then asked for three more. That moment was everything: food that makes grown-ups feel proud, and kids curious enough to try something new. It’s become a little tradition: whenever we want to mark an occasion without fuss, this crostini shows up.

Substitutions and variations

• Beef alternatives: If beef tenderloin is too pricey, a well-trimmed sirloin or flank steak also works. Slice very thinly across the grain.
• Sauce swaps: Prefer less butter? Try a lemon-garlic aioli or chimichurri for a fresher bite. For a creamier base on the crostini, spread mascarpone or herbed cream cheese.
• Make it vegetarian: Replace the beef with grilled portobello slices and the Béarnaise with a lemon-herb hollandaise-style sauce for rich flavor.

FAQs (short, friendly answers)
Q: Can I substitute the beef tenderloin?
A: Yes — beef tenderloin with creamy gravy or a lean sirloin will work in a pinch. Just adjust grilling time and slice thinly.

Q: How do I store leftovers?
A: Store crostini components separately. Keep beef in an airtight container in the fridge for 2–3 days. Béarnaise should be used within a day and reheated gently over warm water.

Q: Can I make Béarnaise ahead?
A: You can, but be careful. Keep it warm in a thermos or over gently simmering water. It’s best the same day. For longer holds, consider a hollandaise-style shortcut.

Q: What are some good wine pairings?
A: A bright Pinot Noir or a crisp Chardonnay complements the richness. For a lighter, bubbly option, Prosecco is a cheerful match.

Serving suggestions
These crostini work beautifully as an appetizer for dinner parties, a luxe snack during wine night, or as a starter for a holiday spread. Pair with a simple arugula salad dressed with lemon and olive oil to cut through the richness.
