Steps
Before you start
- Have all ingredients measured and ready (mise en place), especially shrimp patted dry to ensure crispy searing
- Choose a sourdough loaf with a sturdy crust and open crumb that won't fall apart when toasted
- Bring shrimp to room temperature 10 minutes before cooking for even searing
Roast garlic cloves
- In a small skillet over medium-low heat, add 2 tablespoons (30 ml) of the neutral oil and place the 4 whole garlic cloves in the pan.
- Adjust heat so the garlic sizzles gently but doesn't brown too fast—you want them to turn golden and tender, infusing the oil.
- Stir occasionally, cooking for about 6–8 minutes until the cloves are very soft and just beginning to turn golden.
- The oil will smell sweet and nutty.
- Transfer the garlic and oil to a small bowl and let cool for 1 minute.

Ready when: Garlic cloves are very soft, golden in color, and easily pierced with a fork
Tip: Low heat is essential—high heat will burn the garlic and make the aioli bitter. The oil flavor is as important as the garlic itself.
Make roasted garlic aioli
- Press the roasted garlic cloves with the back of a fork in the small bowl to break them down into a paste (you should have about 1 tablespoon of soft garlic puree).
- Add the egg yolk and Dijon mustard, then whisk together for 30 seconds until combined and pale.
- Slowly drizzle in the remaining ¾ cup (150 ml) neutral oil while whisking constantly—start with just a few drops, whisking after each addition.
- Once the mixture begins to emulsify and thicken (after about 2 tablespoons of oil), you can add the oil in a thin stream while continuing to whisk.
- When all the oil is incorporated, whisk in the 1 tablespoon lemon juice and a pinch of salt and pepper.
- The aioli should be thick, glossy, and pale (like mayonnaise).
- If it breaks (becomes grainy or separates), start over with a fresh egg yolk in a clean bowl and slowly whisk the broken aioli into it drop by drop.

Ready when: Aioli is thick, glossy, pale in color, and holds a peak when the whisk is lifted
Tip: Temperature matters—cold oil into cold egg yolk helps emulsion. Never rush: slow oil addition is the key to a stable aioli. If it looks thin or grainy after the oil is fully added, it may have broken; start the rescue with a fresh egg yolk.
Toast sourdough slices
- Heat a large skillet over medium-high heat.
- Once hot, lay the sourdough slices in a single layer (work in batches if needed).
- Toast for 2–3 minutes per side until the bread is golden-brown with light char marks but still tender inside, not rock-hard.
- If using softened butter, lightly brush one side during the last 30 seconds of toasting for richness.
- Transfer toasted slices to a clean cutting board or plate.

Ready when: Bread is golden-brown with light char, still has a tender crumb inside, and is warm to the touch
Tip: Don't walk away—bread can go from perfect to burnt in seconds. The slices should still have some give; over-toasting makes them hard and unable to hold the toppings.
Sear shrimp until crispy
- Return the skillet to medium-high heat (don't wipe it; any bread crumbs add flavor).
- Add 1 tablespoon (15 ml) of fresh neutral oil and heat for 30 seconds until shimmering.
- Working in two batches if needed, lay the shrimp in the pan in a single layer.
- Sear without moving them for 2 minutes until the bottoms are pink and opaque with light golden edges.
- Flip and cook the other side for another 1–2 minutes until the shrimp is just cooked through and curled.
- Season with salt and pepper.
- Transfer to a clean plate.

Ready when: Shrimp are opaque throughout, pink, and curled; flesh is firm when pressed but still moist
Tip: Don't move the shrimp while they sear—you want that golden crust. Crowding the pan lowers heat and creates steam; work in batches if needed. Overcooked shrimp becomes tough and rubbery.
Assemble tartines
- Spread about 1½ tablespoons of roasted garlic aioli on each warm toasted sourdough slice.
- Top with 3–4 seared shrimp per tartine.
- Garnish with a pinch of fresh chopped parsley and a light dusting of fleur de sel and black pepper.
- Arrange tartines on a serving platter and serve immediately with lemon wedges on the side for squeezing.

Ready when: Tartines are ready to serve and eat immediately while bread is still warm and shrimp are at peak freshness
Tip: Assemble just before serving—warm toast combined with cool aioli and warm shrimp creates the best texture. If you must wait a few minutes, keep tartines uncovered so the bread doesn't steam and soften.
Good to know
Tips
- For a silkier aioli, use room-temperature ingredients and whisk by hand rather than with a food processor, which can overwork the emulsion. Patience with the oil drizzle pays off.
- Pat shrimp very dry before searing—any surface moisture prevents browning. Bring them to room temperature 10 minutes before cooking so they cook evenly.
- Roasting whole garlic cloves in oil mellows and sweetens them far beyond raw minced garlic; the oil becomes an asset in the aioli, not a filler.
- Serve tartines within a minute of assembly so the warm bread, cool aioli, and warm shrimp create a textural contrast. Once they sit, the bread softens and loses appeal.
Make ahead
The roasted garlic aioli can be made up to 2 days ahead and stored covered in the refrigerator. Bring to room temperature (or thin with 1 teaspoon water at a time) before spreading. Toast the bread and sear the shrimp no more than 15 minutes before serving to keep everything warm and crisp.
Storage & reheating
Leftover aioli keeps refrigerated in an airtight container for up to 3 days. Do not reuse raw egg yolk after tasting or if any tartine residue has touched it. Leftover tartines do not store well due to the contrast of textures; assemble to order for best results. Sourdough bread can be wrapped and frozen for up to 2 weeks and toasted fresh before serving.
Substitutions
- large egg yolk → 1 tablespoon (15 g) whole-egg mayonnaise mixed with the roasted garlic and mustard, then whisk in the oil slowly. A safer swap if you're concerned about raw egg; the aioli will be slightly less silky but still delicious.
- sourdough bread loaf → Crusty baguette or ciabatta, sliced diagonally into ½-inch rounds. Any sturdy, crusty bread works. Avoid soft white bread, which will fall apart under toppings.
- fresh flat-leaf parsley → Fresh tarragon, chives, or a mix of both. Each brings a slightly different flavor; tarragon is more French, chives more delicate.
- large shrimp, peeled and deveined → Crispy pancetta or prosciutto crisps, or sautéed white fish (halibut or cod cut into small pieces). Protein options that work equally well for texture and flavor; adjust cooking time accordingly.
