Chef's knife (very sharp)

Steps

Before you start

Buy beef from a butcher you trust and ask for the leanest grade (eye of round or strip loin), ground fresh while you watch or packaged that morning
Chill all prep bowls and the cutting board in the freezer for 15 minutes before you begin
Have all ingredients prepped and arranged before you start assembling—raw beef must spend minimal time at room temperature

1
Chill mise en place
- Place the chilled cutting board, a small bowl, and a shallow serving dish in the freezer.
- Slice the shallots very thinly, keeping them separated into rings.
- Pat the capers completely dry with paper towels and set aside.
- Have the lemon zested and juiced.
- Measure all spices into a small ramekin.

Tip: Keeping everything cold prevents the beef from warming too much, which can compromise both texture and food safety.
2
Toast the bread
- Heat a large skillet or griddle over medium-high heat (6/10 heat level).
- Lightly brush both sides of each sourdough slice with softened butter.
- Once the pan is hot and the butter foams, arrange the bread in a single layer and toast for 1½ to 2 minutes per side until golden brown and crisp, with no soft center.
- Work in batches if needed.
- Transfer to a cooling rack or clean plate.

Ready when: Bread is golden brown, crisp to the bite, with a toasted aroma
Tip: Don't toast too long or the bread becomes brittle and will crack when topped. Aim for a light, crisp exterior and warm interior.
3
Season and dress the beef
- Immediately after toasting (while bread is still warm), remove the chilled bowl from the freezer.
- Add the hand-chopped beef to the cold bowl, breaking it up gently with a fork if it's clumped.
- Sprinkle with fleur de sel, white pepper, ground coriander, and a tiny pinch of cayenne if using.
- Drizzle in 2 tablespoons of the olive oil and the lemon juice, then fold gently 3 to 4 times with a fork until just combined.
- Taste and adjust seasoning—tartare should taste bold but not overly spiced.
- Set aside.

Ready when: Beef is evenly colored and just combined, still cold to the touch
Tip: Don't overwork the beef—fold it gently so it remains loose and tender, not pasty. A light touch is essential.
4
Spread mustard on toast
- While the bread is still warm, spread about 1 teaspoon of Dijon mustard on each toast slice, distributing it evenly with the back of the spoon.

Tip: Spreading mustard on warm bread helps it set slightly and creates better flavor integration.
5
Top with tartare
- Using a small spoon or caviar spoon, place a generous mound of the spiced beef tartare (about 1½ tablespoons) in the center of each toast.
- Do not press it down; let it sit slightly proud of the bread.

Tip: Build these tartines just before serving so the bread stays crisp and the beef stays cold.
6
Garnish and finish
- Scatter a small pinch of capers on and around each tartare mound.
- Arrange a few shallot rings on top of each.
- Drizzle lightly with the remaining 1 tablespoon of olive oil.
- If using cornichons and chives, tuck a few thin slices of cornichon alongside and sprinkle chives over the top.
- Add a final whisper of fleur de sel and a grind of white pepper.

Tip: Garnish right before serving so shallots stay crisp and capers add their briny pop.

Tips

Source your beef from a butcher with high turnover and excellent hygiene standards. Ask specifically for tartare-grade beef and confirm how fresh it is. Never use beef from a regular grocery store unless explicitly labeled 'beef for tartare' or ground fresh in front of you.
The spice blend—coriander, white pepper, and a whisper of cayenne—mimics the warm notes of classic French seasoning without overpowering the delicate beef. Taste as you season; it's easy to add but impossible to remove.
Assemble tartines at the very last moment. The beauty of this dish lies in the contrast: a crisp, warm toast against cold, tender beef and the sharp bite of capers and shallots. Build them no more than 2 minutes before serving.
White pepper is essential here because black pepper specks can look unappealing in tartare. If you only have black pepper, grind it very fine and use less.

Make ahead

Sourdough can be sliced and toasted up to 4 hours ahead; store in an airtight container at room temperature. Beef tartare seasoning mix can be measured ahead, but the beef must not be dressed more than 15 minutes before serving. Shallots and capers can be prepped 2 hours ahead and refrigerated separately.

Storage & reheating

Serve immediately. Leftover toasted bread keeps in an airtight container at room temperature for 2 days, but tartare is best consumed the day it is made and should never be eaten raw more than 2 hours after preparation. Do not freeze.

Substitutions

beef for tartare → Venison or duck breast tartare. Use the same weight and prep method. Venison adds gaminess; duck is richer. Both are excellent alternatives in French cuisine.
Dijon mustard → whole-grain mustard. Provides a speckled appearance and slightly more texture. Use the same amount.
sourdough bread → dark rye or pumpernickel bread. Toast the same way. Rye's earthiness complements beef tartare beautifully and is traditional in Nordic versions.
extra-virgin olive oil → walnut oil. Use half the amount (1½ tablespoons total) for a more pronounced, nutty flavor that suits beef tartare well.
