Ingredients

Makes about 24 crostini (serves 6–8 as an appetizer)

For the crostini

1 French baguette, sliced into 1/2-inch rounds (about 24 slices)
2 tablespoons olive oil
Salt and pepper, to taste

For the beef

1 1/2 lb beef tenderloin, trimmed (or center-cut filet), very well chilled
2 tablespoons olive oil
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
1 teaspoon garlic powder
1 tablespoon unsalted butter

For the Parmesan Cream Sauce

1 tablespoon unsalted butter
1 small shallot, finely minced
1 garlic clove, minced
1/2 cup dry white wine or low-sodium chicken broth
1 cup heavy cream
3/4 cup freshly grated Parmesan cheese
Freshly ground black pepper, to taste
Pinch of nutmeg (optional)

For assembly

2 tablespoons fresh parsley, chopped
1 tablespoon fresh chives, thinly sliced
A drizzle of balsamic glaze (optional)
Arugula leaves (optional, for a peppery pop)

Notes: If you prefer, substitute a pre-cut beef tenderloin roast or even steak medallions. This recipe is flexible.

Step-by-Step Directions

Preheat and prep:
- Preheat oven to 400°F (200°C). Line a baking sheet with parchment.
- Toss baguette slices with 2 tablespoons olive oil, salt, and pepper. Arrange in a single layer and toast in the oven for 8–10 minutes until golden and crisp. Set aside.

Sear the beef:
- Pat the beef tenderloin dry with paper towels. Season evenly with kosher salt, black pepper, and garlic powder.
- Heat 2 tablespoons olive oil in a heavy skillet over medium-high heat until shimmering. Add the tenderloin and sear on all sides until a golden crust forms — about 2–3 minutes per side for a medium-rare finish depending on thickness.
- Add 1 tablespoon butter to the pan for the last 30 seconds, spooning it over the beef. Transfer the tenderloin to a cutting board and tent loosely with foil. Let it rest for 8–10 minutes (important for juicy, even slices).
Make the Parmesan cream sauce:
- In the same skillet, reduce heat to medium and add 1 tablespoon butter. Sauté the minced shallot for 1–2 minutes until translucent, then add the garlic and cook 20–30 seconds.
- Pour in the white wine (or chicken broth) to deglaze the pan, scraping up browned bits. Let it reduce by about half — 2–3 minutes.
- Stir in the heavy cream and bring to a gentle simmer. Add the grated Parmesan in small handfuls, whisking until smooth. Season with black pepper and a pinch of nutmeg if using. If the sauce seems too thick, add a splash more cream or a tablespoon of milk.
- Taste and adjust salt/pepper. Keep warm on low.
Slice the beef:
- Slice the rested tenderloin into very thin medallions (about 1/8–1/4 inch thick). Thin slices are easier to eat on crostini and feel delicate.
Assemble the crostini:
- Place a small spoonful of parmesan cream sauce on each toasted baguette round.
- Top with a slice or two of beef tenderloin.
- Spoon a bit more sauce over the beef, sprinkle with chopped parsley and chives, and add an arugula leaf if desired.
- Finish with a tiny drizzle of balsamic glaze for a sweet-tart lift if you like.
Serve immediately:
- Arrange on a platter and serve warm. These are best eaten within an hour of assembly so the crostini stays crisp.

Cooking Tips (Because Life Gets Busy)

Resting is non-negotiable. Let the beef rest after searing to keep it juicy — that 8–10 minutes makes a big difference.

Keep slices thin. Thin medallions sit nicely on crostini and are easier to eat at a party.
Make sauce ahead. Parmesan cream keeps well for up to 48 hours in the fridge. Warm it gently before using.
Bread stays crisp if toasted right before assembly. If you must prepare early, keep them in an airtight container and re-toast for 3 minutes.

Don’t fret about lumps. If your sauce looks a little grainy from the cheese, whisk vigorously or strain; it will still taste amazing.

A Little Backstory

This recipe started as a fancy test for a family gathering. Patricia wanted an appetizer that felt special but wouldn’t have me glued to the stove all evening. I seared a modest tenderloin, stirred up a cheesy cream sauce, and the crostini disappeared fast. My kids loved the bite-sized format (and yes, they ate the arugula, much to my surprise). Since then, it’s my “I have guests but only 30 minutes” secret weapon.

FAQs

Q: Can I use a different cut of beef?
A: Absolutely. Strip steak, ribeye medallions, or sirloin tip can work — but adjust searing time and slice thinly. For budget-friendliness, flank steak works if sliced thin against the grain.

Q: Can I make this vegetarian?
A: Try roasted mushrooms or seared portobello slices instead of beef, with the same parmesan cream sauce — still elegant, still delicious.

Q: How do I store leftovers?
A: Keep the sauce in an airtight container for up to 48 hours. Store beef separately. Crostini will soften if stored together, so assemble only what you’ll serve within an hour.

Q: Can I use store-bought sauce?
A: Sure! A good-quality alfredo can be jazzed up with extra Parmesan, a splash of white wine, and a pinch of nutmeg.

Q: Is this recipe freezer-friendly?
A: You can freeze the seared beef tightly wrapped for up to 3 months, but the sauce and crostini are best made fresh.

Serving Ideas and Pairings

Serve with a simple arugula and pear salad dressed in lemon vinaigrette to balance richness.
Pair with a medium-bodied red wine (Pinot Noir) or a crisp Chardonnay to complement the cheese and beef.

Add pickled red onions to the crostini for a bright contrast.
