Spring on a Slice: Warm White Asparagus & Avocado Tartines
Listen, my loves, if there is one thing I cannot abide, it is a heavy lunch when the California sun is shining. The inspiration for this tartine came to me on a lazy Sunday afternoon sitting on my patio, craving the elegance of a Parisian bistro but needing the bright, unapologetic freshness of the West Coast. I remember finding these gorgeous, ghostly white asparagus stalks from my favorite farmer up in Yolo County. He handed me a bunch with hands still dusted in earth, and I knew exactly what to do. I blanched them gently and draped them over thick, charred sourdough slathered in smashed avocado. But the real magic? A quick Meyer lemon and charred shallot emulsion. Just whisk it up like a simple beurre blanc, but let it get thick, glossy, and impossibly bright. This dish is so special to me because it bridges my two worlds perfectly: French technique and California soul. Feel free to make it your own! Swap the sourdough for a rustic rye, or toss some toasted hazelnuts on top for a little crunch. Just promise me you will serve it with a chilled glass of skin-contact Chenin Blanc. Et voilà, perfection.

Warm White Asparagus & Avocado Tartines with Meyer Lemon-Shallot Emulsion
Bistro patio lunches in the California sun demand something elegant but entirely effortless. Enter the tartine. We are taking tender, beautifully blanched white asparagus—a springtime jewel from my favorite farmer up in Yolo County—and draping it over creamy smashed avocado on thick, charred sourdough. The real magic happens when we pour over a quick, glossy Meyer lemon and charred shallot emulsion. It is rich, it is unapologetically bright, and it practically demands a chilled glass of skin-contact Chenin Blanc.

Timeline
Ingredients
- 3 tbsp olive oil(divided)
- 3 tbsp capers(drained and patted very dry)
- 1 lb white asparagus(thick spears, woody ends trimmed)
- 1 tbsp kosher salt(for blanching water)
- 2 whole Meyer lemons(divided for juice)
- 4 slices sourdough bread(cut thick)
- 1 large shallot(finely minced)
- 1/4 cup dry white wine(Sauvignon Blanc or Chenin Blanc preferred)
- 6 tbsp unsalted butter(very cold, cut into small cubes)
- 2 whole ripe avocados(halved and pitted)
- 1 pinch flaky sea salt(to taste)
- 1 pinch white pepper(freshly ground)
- 2 tbsp fresh tarragon(finely chopped)
Instructions
- 1
Heat 2 tbsp olive oil in a small skillet over medium-high heat. Add the dried 3 tbsp capers and fry until they open up like little flowers and get incredibly crispy, about 4 to 5 minutes. Use a slotted spoon to transfer them to a paper towel. Leave the fragrant oil in the pan for the bread!
5 min
Tip: Make sure the capers are completely dry before they hit the hot oil, otherwise they will violently splatter and ruin your patio lunch vibe.
- 2
While the capers fry, prep the 1 lb white asparagus by peeling them starting just below the delicate tips, snapping off the woody ends. Bring a large wide pot of water to a rolling boil. Season it generously with 1 tbsp kosher salt and a squeeze of juice from 1/2 Meyer lemon.
10 min
Tip: White asparagus has a thicker, more fibrous skin than its green cousin. Don't be shy—peel off a good, thick layer so every bite is melt-in-your-mouth tender.
- 3
Drop the peeled 1 lb white asparagus into the gently boiling water. Let them blanch until tender but still holding a proud shape, about 6 to 8 minutes depending on thickness. Gently remove them with tongs and let them drain on a clean kitchen towel.
8 min
Tip: Test for doneness by piercing the thickest part of a stalk with a paring knife; it should slide in with little resistance.
- 4
Add the remaining 1 tbsp olive oil to your caper skillet. Toast the 4 slices sourdough bread over medium heat until the edges are beautifully charred and the centers are golden. Set aside on your serving plates.
5 min
Tip: I love using the caper-infused oil for the bread; it builds layers of flavor without needing to reach for more ingredients.
- 5
In a small saucepan, combine the minced 1 large shallot, 1/4 cup dry white wine, and the freshly squeezed juice of 1 Meyer lemon. Simmer over medium-low heat until the liquid is heavily reduced to just about a tablespoon. This sharp, acidic reduction is the backbone of your emulsion.
8 min
Tip: Watch the pan closely at the end of the reduction; it goes from perfect to scorched in seconds.
- 6
While the liquid reduces, scoop the flesh of the 2 whole ripe avocados into a mixing bowl. Add 1 pinch flaky sea salt and the juice from the remaining 1/2 Meyer lemon. Roughly smash everything together with a fork—we want a chunky, rustic texture, not a smooth purée.
3 min
Tip: The avocado acts as the rich, cool foundation that contrasts perfectly with the warm asparagus and sauce.
- 7
Turn the saucepan heat under your reduction to the absolute lowest setting. Whisking continuously and vigorously, add the very cold 6 tbsp unsalted butter one or two small cubes at a time. The sauce will magically emulsify into a thick, glossy cream. Remove from heat immediately and stir in 1 pinch white pepper.
4 min
Tip: If the sauce looks like it's starting to break or separate, immediately pull it off the heat and whisk in a splash of cold water to bring the emulsion back together.
- 8
Slather the smashed avocado generously over the warm sourdough toasts. Drape the blanched white asparagus spears right on top. Generously spoon the warm, velvety Meyer lemon emulsion over the asparagus, allowing it to drip down the sides. Scatter the dish with your crispy capers and the finely chopped 2 tbsp fresh tarragon.
3 min
Tip: Serve immediately while the sauce is warm and the bread is crisp. It's the ultimate high-low California bistro bite.
Chef's Notes
The key to this dish is temperature contrast. You want the cool, rich avocado against the warm, earthy asparagus and the silky, warm emulsion. Don't let your beurre blanc sit around too long—make it right before you plan to eat! If you cannot find Meyer lemons, a mix of regular lemon juice and a tiny splash of fresh orange juice does a lovely job mimicking that floral sweetness.

French soul, California sun
I grew up in a small village outside Lyon, where my grandmother taught me that the best meals come from respecting your ingredients. After training at Le Cordon Bleu and spending years in Parisian kitchens, I moved to San Francisco and fell in love with California's farmers markets and wine country. Now I cook the food I wish my grandmother could taste—French technique with California abundance, where a perfect roast chicken might come with Meyer lemon and wild fennel instead of tarragon.
