Buttermilk Poached Egg and Herb Stir-Fried Noodles
Tender egg noodles tossed with browned butter, shallots, and fresh herbs, topped with a silky buttermilk-poached egg. The buttermilk adds a subtle tang to the poaching liquid, creating a delicate egg white while keeping the yolk perfectly runny. This French-inspired dish is elegant enough for dinner yet simple enough for a weeknight meal.

Steps
Before you start
- Bring a large pot of salted water to boil for the noodles
- Have all herbs and aromatics prepped and measured
- Bring a second pot of buttermilk-water mixture to a gentle simmer for poaching
Prepare poaching liquid
- Combine buttermilk, water, and white vinegar in a shallow saucepan (10 inches / 25 cm).
- Bring to a gentle simmer over medium heat, adjusting the heat so small bubbles rise slowly to the surface—the liquid should steam gently but never boil vigorously.
- Season lightly with salt.
- Keep at this temperature throughout poaching.

Ready when: Small bubbles rise slowly; liquid steams gently
Tip: A rolling boil will shred the egg whites. The buttermilk-vinegar combination creates a milky, slightly acidic poaching liquid that sets the egg whites quickly and gently.
Cook egg noodles
- Bring a large pot (at least 4 quarts / 4 liters) of salted water to a rolling boil.
- Add egg noodles and cook according to package directions (usually 5–6 minutes) until al dente.
- Reserve 1 cup (240 ml) of pasta water before draining.
- Drain noodles in a fine-mesh sieve but do not rinse.

Ready when: Noodles are tender but still have a slight firmness when bitten
Tip: Reserve the starchy pasta water—it will help emulsify the butter and aromatics later. Do not rinse; the starch helps bind the sauce.
Brown butter with aromatics
- In a large 12-inch (30 cm) skillet, melt butter over medium-high heat.
- Once foaming, add sliced shallots and cook, stirring often, for 3–4 minutes until they turn golden and fragrant.
- Add minced garlic and cook for 30 seconds more, stirring constantly, until fragrant.
- The butter should smell rich and nutty.

Ready when: Shallots are golden and caramelized at the edges; butter is nutty and fragrant
Tip: Watch the heat carefully—if the butter burns or the garlic blackens, start over. The goal is a rich, toasted flavor, not charring.
Toss noodles with butter mixture
- Add the drained egg noodles to the skillet with the browned butter and shallots.
- Toss continuously over medium-high heat for 2–3 minutes, breaking up any clumps.
- As you toss, splash in 2–3 tablespoons (30–45 ml) of the reserved pasta water at a time, tossing between additions.
- The starch in the water will create a light, glossy coating.
- The noodles should separate and coat evenly with golden butter.

Ready when: Noodles are glossy, well-coated, and moving freely in the pan
Tip: Toss constantly to prevent sticking and ensure even coating. If the pan looks too dry, add pasta water 1 tablespoon at a time.
Add fresh herbs
- Remove the skillet from the heat.
- Add parsley, tarragon, and chives to the noodles.
- Toss gently to distribute the herbs throughout.
- Taste and season with salt and black pepper.
- If using, toss in the lemon zest for brightness.

Ready when: Herbs are evenly distributed throughout the noodles; herbs are bright green
Tip: Add herbs off the heat so they stay vibrant and don't wilt from prolonged heat. Taste and adjust seasoning before plating.
Poach the eggs
- Working with one egg at a time, crack it gently into a small bowl or ramekin.
- Gently slide each egg into the simmering buttermilk poaching liquid by tilting the bowl just above the surface and letting it slip in.
- The egg white will immediately begin to turn opaque and cloud the surrounding liquid.
- Poach for 3–4 minutes for a runny yolk and set whites.
- Use a slotted spoon to gently lift the egg from the liquid.

Ready when: Egg white is opaque and set; yolk jiggles slightly when moved with spoon
Tip: A gentle slide into simmering liquid prevents the white from breaking apart. If the liquid boils even slightly, the egg will shred. The cold egg straight from the refrigerator helps set the whites quickly.
Plate and serve
- Divide the herb-buttered noodles between two bowls or plates, creating a loose nest.
- Use a slotted spoon to place one warm poached egg on top of each nest of noodles.
- Spoon 1–2 tablespoons (15–30 ml) of the warm buttermilk poaching liquid gently over each egg.
- Garnish with a small pinch of fleur de sel or finishing salt and a few grinds of black pepper.

Tip: Serve immediately while the noodles are warm and the yolk is still runny. The buttermilk liquid creates a silky sauce when combined with the yolk.
Good to know
Tips
- The buttermilk in the poaching liquid is essential—it creates a milky, gentle cooking environment that sets the egg whites quickly while keeping the yolk runny. Never skip this step or use only water.
- Cold eggs straight from the refrigerator poach more evenly. The cold yolk takes longer to set than the white, creating the perfect contrast.
- If you're nervous about poaching, crack the egg into a small ramekin or cup first, then gently slide it into the liquid. This gives you more control and prevents splashing.
- Taste the noodles before plating—the salt level should be seasoned to your preference since you'll be adding the warm buttermilk liquid which is also gently salted.
Make ahead
The noodles can be cooked and drained up to 2 hours ahead; store uncovered at room temperature. The herb mixture can be prepped up to 4 hours ahead and stored in an airtight container. Reheat the noodles by tossing gently in a warm skillet with a splash of pasta water for 1–2 minutes before browning the butter and shallots. Always poach the eggs fresh to order for the best result.
Storage & reheating
Best served immediately. Leftover plain noodles (without egg) can be refrigerated in an airtight container for up to 2 days; reheat gently in a skillet with a splash of water. Do not refreeze poached eggs. Store remaining buttermilk-herb mixture in the refrigerator for up to 3 days.
Substitutions
- fresh tarragon → fresh chervil or fresh dill (1 tablespoon / 3 g). Tarragon is classic in French cooking, but chervil offers a milder anise flavor and dill adds a bright, slightly peppery note. Both work beautifully with poached eggs.
- buttermilk → whole milk mixed with 1 tablespoon lemon juice (let sit 5 minutes before using). This creates an acidic poaching medium similar to buttermilk, though the texture may be slightly less delicate.
- egg noodles → fresh ribbon pasta or fettuccine (5–6 oz / 150 g). Fresh pasta cooks in 2–3 minutes and has a silkier texture. Adjust cooking time accordingly.
- white vinegar → white wine vinegar or lemon juice (1 tablespoon / 15 ml). The acidity helps set the egg white. White wine vinegar adds a slightly more complex flavor; lemon juice is more assertive.
