Five-Spice Duck Breast with Flavor Grenade Pluot Sauce, Roasted Summer Squash & Spring Onions, and Roasted Hannah Sweet Potatoes
Caption calls out three components. Photo shows medium-rare sliced duck under a chunky pluot pan sauce, charred summer squash with spring onions, and split roasted Hannah sweet potatoes. I’m assuming a classic crisp-skin duck sear with a quick pluot-ginger pan sauce; squash glazed with aged balsamic; and whole roasted Hannahs finished with ghee. Bay Area August seasonality fits pluots, squash, and spring onions.

Crisp-Skinned Five-Spice Duck Breast
Dry-brined five-spice seasons the fat cap and perfumes the meat. A cold-pan render yields glassy-crisp skin while keeping the meat rosy.
Ingredients
- 4 pieces duck breasts, skin-on (6–8 oz each)
- 2 tsp Chinese five-spice powder
- 2 tsp kosher salt
- 1/2 tsp black pepper
Instructions
- Pat duck dry. Score skin in a 1/2-inch crosshatch, cutting only through fat. Season all over with salt, five-spice, and pepper; rest uncovered in the fridge 30–60 minutes (up to overnight).
- Set a heavy skillet over medium-low with the breasts skin-side down in a cold pan. Slowly render 8–12 minutes, adjusting heat to keep sizzling gentle, until skin is deep gold and much of the fat has rendered (about 1/4 cup in pan). Spoon off and reserve excess fat, leaving a thin film in the pan.
- Flip and sear meat-side 1–2 minutes. Either finish on the stovetop over low heat or in a 350°F oven 4–6 minutes to 129–132°F internal for medium-rare.
- Rest 8–10 minutes before slicing across the grain into 1/2-inch slices. Save resting juices for the sauce.
Notes
- Sous vide option: season, bag, and cook 133°F for 1–2 hours. Dry well and sear skin-side down 5–7 minutes to crisp, then briefly kiss the flesh side.
- If your five-spice blend is very fresh/potent, use 1.5 tsp and taste sauce before adding more spice elsewhere.
Flavor Grenade Pluot–Ginger Pan Sauce
Tart-sweet pluots, ginger, and vinegar cut the duck’s richness; coconut aminos add umami without soy.
Ingredients
- 2 tbsp reserved duck fat (from searing)
- 1 large shallot, finely minced
- 1 tbsp fresh ginger, finely minced or julienned
- 4 medium Flavor Grenade pluots, firm-ripe, pitted and sliced into 1/2-inch wedges
- 2 tbsp unseasoned rice vinegar
- 1 tbsp coconut aminos
- 1/2 cup duck or chicken stock (or water)
- 1 tsp honey (optional, to balance)
- kosher salt and black pepper, to taste
- resting juices from the duck
Instructions
- Pour off all but 2 tbsp fat from the duck pan. Over medium heat, sauté shallot and ginger until translucent and fragrant, 2–3 minutes.
- Add pluot wedges and toss 60–90 seconds.
- Deglaze with rice vinegar and coconut aminos, scraping up fond. Add stock and simmer 3–5 minutes until pluots soften but hold shape and the sauce lightly coats a spoon.
- Stir in duck resting juices. Taste; add a touch of honey if too tart, more vinegar if too sweet. Season with salt and pepper. Keep warm off heat.
Notes
- If using another pluot/plum, choose firm-ripe fruit so it doesn’t collapse.
- Too thick? Add a splash of stock. Too thin? Simmer 1–2 minutes more.
- For extra spice warmth, add a pinch of five-spice at the end—go light so it doesn’t get bitter.
Roasted Summer Squash and Spring Onions with Aged Balsamic
Hot-sheet roasting gives deep browning; a quick hit of aged balsamic glazes and brightens without making the vegetables soggy.
Ingredients
- 2 lb mixed summer squash (zucchini, yellow crookneck, pattypan), cut into 3/4-inch pieces
- 6 pieces spring onions, bulbs halved lengthwise (greens trimmed to 4–5 inches)
- 3 tbsp olive oil
- 1 1/4 tsp kosher salt
- 1/2 tsp black pepper
- 1 1/2 tbsp aged balsamic vinegar
Instructions
- Heat oven to 450°F with a rimmed sheet pan preheating inside.
- In a bowl, toss squash and spring onions with olive oil, salt, and pepper.
- Spread onto the hot pan cut-sides down. Roast 15 minutes until well browned on edges.
- Toss, drizzle with aged balsamic, and roast 3–5 minutes more until glossy and lightly charred in spots. Adjust salt and finish with a thread of olive oil if desired.
Notes
- If your balsamic isn’t syrupy, reduce 3 tbsp in a small pan to ~1.5 tbsp before tossing so it glazes instead of puddling.
- Add chili flakes or thyme if you like heat/herb notes, though the original looks straight and simple.
Roasted Hannah Sweet Potatoes
Slow roasting concentrates the white-fleshed Hannahs into a custardy interior with caramelized skins; a quick broil crisps the edges.
Ingredients
- 4 pieces Hannah (white-fleshed) sweet potatoes, medium, scrubbed
- 1 tbsp olive oil
- 3 tbsp ghee, for serving
- 1 tsp kosher salt, plus more to finish
- black pepper, to taste
Instructions
- Heat oven to 400°F. Prick potatoes a few times, rub with olive oil and 1 tsp salt.
- Roast on a rack set over a foil-lined sheet 60–80 minutes, until very tender and skins are deeply colored.
- Rest 5 minutes. Split lengthwise, add ghee, and lightly smash to expose flesh. Season with salt and pepper.
- Optional: Broil 2–3 minutes to blister the edges before serving.
Notes
- Sizes vary—add time for large potatoes. If you rendered plenty of duck fat, spoon some over before the optional broil.
Overall Timing / Workflow
Staggers long-roast potatoes with a quick duck sear and fast veg roast so everything lands hot without crowding the stove.
Instructions
- Start: Heat oven to 400°F. Get potatoes roasting (60–80 minutes).
- While potatoes roast, score/season duck; slice pluots; mince shallot and ginger; cut squash and spring onions.
- When potatoes have ~30 minutes left, place a clean sheet pan in the oven and raise temp to 450°F for the squash (potatoes can stay in).
- About 15 minutes before eating, sear duck skin-side down slowly. Flip and finish on stovetop to 129–132°F (or briefly in a 350°F oven if you have a second oven). Rest duck.
- Roast squash/onions 15 minutes, toss with balsamic, and finish 3–5 minutes while you make the pan sauce in the duck skillet.
- Plate: split potatoes with ghee; slice duck and sauce; add squash and onions. Serve immediately.
Notes
- If using one oven and finishing duck in the oven, roast squash after the duck is out (it’s fast); keep potatoes warm tented with foil.
Plating
Simple arrangement keeps duck skin crisp while the pluot sauce shines and vegetables stay distinct.
Instructions
- Warm plates. Fan sliced duck off-center, keeping most skin above the sauce line.
- Spoon pluot sauce over the meat side and onto the plate, not directly onto the skin.
- Nest a mound of balsamic-glazed squash and spring onions alongside.
- Add a split roasted Hannah sweet potato with a knob of ghee. Finish with flaky salt and fresh black pepper.
Notes
- If you want extra gloss, whisk a small cube of cold ghee into the warm sauce right before plating.
Leftover Path
Turns high-value duck and seasonal sauce into next-day meals without losing texture.
Instructions
- Storage: Cool components separately; refrigerate up to 3 days. Keep sauce in a jar.
- Reheat duck gently: place slices skin-side down in a cold nonstick pan; warm over low until skin re-crisps and meat is just warm, or serve room-temp.
- Lettuce cups: slice cold duck, add a spoon of pluot sauce, herbs, and cucumber in butter lettuce.
- Breakfast hash: cube sweet potatoes, sear in duck fat with leftover spring onions; add duck at the end and a squeeze of vinegar.
- Frittata: chop roasted squash/onions and fold into eggs; serve with a dab of pluot sauce.
- Pluot sauce as chutney: reduce briefly and serve with grilled pork or spoon over unsweetened coconut yogurt.
Notes
- Freeze sauce in an ice cube tray if you won’t use it within 3 days.
