These crisp, buttery toast triangles are elevated with tender seared beef and a creamy horseradish sauce. Start by preparing the zesty horseradish cream, then sear seasoned beef to medium-rare perfection. Broil buttery toast triangles until golden and crisp. Layer the toast with horseradish cream, sliced beef, and a sprinkle of chives for an elegant appetizer or light lunch. Serve warm to enjoy the contrast of textures and flavors.
One evening, a friend arrived unannounced with a bottle of wine, and I had twenty minutes to turn something simple into something memorable. I'd just picked up beautiful beef tenderloin from the butcher, and inspiration struck—crispy toast, seared beef, a tangy cream. Those first golden triangles came out of the broiler nearly perfect, and watching his face when he bit into one made me realize appetizers don't need to be complicated to feel special.
I've made these countless times now, and what strikes me most is how they disappear fastest at the table—people grab them before they even sit down. That horseradish cream is the real magic; it transforms simple seared beef into something that feels restaurant-quality, the kind of thing that makes everyone ask for the recipe.
Ingredients
- Beef tenderloin or sirloin, 200 g (7 oz): Tenderloin is more tender and luxurious, but sirloin works beautifully if you're watching your budget—just slice it thinly to ensure tenderness.
- Kosher salt and black pepper: Don't skip seasoning the beef generously; it's the foundation of flavor.
- Olive oil, 1 tbsp: Use good oil here since it's the medium for the sear and contributes to taste.
- White sandwich bread, 4 slices: Standard white bread toasts evenly and has a gentle flavor that lets the beef shine.
- Unsalted butter, 2 tbsp softened: Softened butter brushes on easily and browns beautifully under the broiler.
- Sour cream, 2 tbsp: The creamy base that balances the heat of horseradish; crème fraîche adds richness if you prefer.
- Prepared horseradish, 1 tbsp: This is the backbone—it gives the cream its signature bite and awakens the palate.
- Dijon mustard, 1 tsp: A whisper of mustard rounds out the flavors and adds subtle depth.
- Lemon juice, 1 tsp: Brightness and acidity that keeps the cream from feeling heavy.
- Fresh chives, 1 tbsp chopped: A final green note and gentle onion flavor that feels like a restaurant detail.
- Flaky sea salt, optional: Adds textural contrast and a finishing touch of sophistication.
Instructions
- Mix the horseradish cream first:
- In a small bowl, combine sour cream, prepared horseradish, Dijon mustard, lemon juice, and a pinch of salt and pepper. Taste as you go—you want the horseradish to sing without overwhelming everything. Set it aside while you work on the beef and toast.
- Sear the beef until it's golden and blushing inside:
- Season your beef generously with salt and pepper on both sides. Heat olive oil in a skillet over medium-high heat until it shimmers, then lay the beef down—you should hear a satisfying sizzle. Sear for 2–3 minutes per side, aiming for a golden crust and a gentle blush of pink inside. Transfer to a plate and let it rest for 5 minutes; this keeps it tender and allows the juices to settle.
- Toast the bread while the beef rests:
- Preheat your broiler while the beef relaxes. Trim the crusts from your bread slices and cut each one diagonally into two triangles. Brush both sides generously with softened butter—don't be shy here, that butter is what creates the golden, crispy finish. Arrange the triangles on a baking sheet in a single layer.
- Broil until golden and crisp:
- Place the baking sheet under the broiler for 1–2 minutes per side, watching closely since broilers vary wildly in temperament. You want deep golden triangles with a slight crackle, not burnt edges. This happens faster than you'd think, so stay close.
- Slice the beef thin and against the grain:
- Once the beef has rested, slice it thinly with a sharp knife, cutting perpendicular to the muscle fibers for maximum tenderness. Each slice should be almost translucent.
- Assemble with a light hand:
- Spread a thin layer of horseradish cream on each warm toast point. Top with a slice or two of beef, then a small dollop more cream to anchor it. Finish with a sprinkle of fresh chives and a pinch of flaky salt if you have it. Serve immediately while the toast is still warm and crispy.
I remember pulling a batch of these from the broiler during a small dinner party, and the kitchen filled with the smell of buttered toast and seared beef—a scent that somehow says both "comfort" and "occasion" at the same time. That's when I realized these little triangles had become my go-to for moments when I want to impress without stress.
The Horseradish Secret
Horseradish gets a bad reputation for being aggressive, but when balanced with sour cream, mustard, and lemon, it becomes something almost elegant. The key is tasting as you build the cream—add horseradish a little at a time, stirring between additions, until you hit that sweet spot where it wakes up your palate without making you wince. If you've over-done it, thin it with a touch more sour cream. This cream keeps for two days, so you could make it ahead and assemble the toast points right before serving if life gets busy.
Why the Beef Matters
The quality of your beef here is everything—since it's the star and sliced thinly, you want something tender and flavorful. Beef tenderloin is the indulgent choice and practically melts, but good sirloin will work if you slice it thin and let it rest properly. The sear is quick, just long enough to develop a golden crust that contrasts with a tender, pink center. Medium-rare is where this shines; it's gentle enough to stay juicy but has enough color to look intentional.
Building the Perfect Bite
Assembly is simple, but there's a rhythm to it that matters. Warm toast first, then cream, then beef while everything is still temperate, finishing with the flourish of chives and salt. The contrast of temperatures and textures—crispy, creamy, tender, bright—is what makes these feel more than the sum of their parts. Think of it as building a small, edible moment rather than just stacking ingredients.
- If you want to go fancy, you can add a tiny leaf of microgreen or arugula for color, though chives alone are plenty.
- These are best served immediately, but if you're making them for a crowd, you can keep them warm on a low oven and assemble in batches.
- Leftover horseradish cream is excellent with roasted vegetables or stirred into mashed potatoes the next day.
These toast points have become my favorite way to say "I'm glad you're here" without spending hours in the kitchen. There's something about offering something both elegant and approachable that makes people feel welcome.
