30-Minute Garlic Poached Salmon
Delicate salmon poached in white wine and garlic, finished with a bright lemon caper sauce enriched with Greek yogurt instead of cream. The poaching method keeps the fish moist and tender while infusing subtle wine and garlic notes. Fresh dill and capers add briny, herbaceous complexity. Perfect for weeknight dinners or light entertaining. This version swaps heavy cream for tangy Greek yogurt, making it lighter without sacrificing richness or the classic pairing of salmon with dill and capers.

Tips
Don't skip the gentle simmer; boiling too vigorously breaks apart delicate salmon. Keep heat low and covered.
Stir yogurt off heat to prevent curdling. If sauce breaks, whisk in a splash of cold water off heat.
Use fresh dill if possible; dried loses its bright, herbaceous quality in this bright sauce.
Good to Know
Refrigerate sauce and salmon separately up to 3 days. Reheat salmon gently in a 300F oven wrapped in foil; warm sauce over low heat, adding a splash of water if it's thick.
Make sauce up to 1 day ahead; store covered. Poach salmon no more than 4 hours before serving; keep in poaching liquid in fridge. Reheat gently.
Serve warm on individual plates with sauce spooned over. Pair with roasted vegetables, steamed potatoes, or a light salad. White wine, especially unoaked Chardonnay or Sauvignon Blanc, complements beautifully.
Common Mistakes
Boil the poaching liquid too hard to avoid breaking apart the delicate salmon flesh.
Stir yogurt while the sauce is still hot to avoid curdling; cool slightly or stir off heat.
Reduce the wine fully before adding yogurt to prevent a watery, separated sauce.

FAQ
Can I use frozen salmon filets?
Yes, thaw completely in the fridge first. Pat dry before poaching to remove excess water, which will dilute the poaching liquid and affect cooking time.
What if I don't have Greek yogurt?
Sour cream works 1:1; it's tangier. Heavy cream or creme fraiche are richer alternatives. Stir any off heat to prevent curdling from residual heat.
Can I freeze leftovers?
Freeze salmon and sauce separately for up to 2 months. Thaw in the fridge overnight. Sauce may separate slightly; whisk in 1-2 teaspoons water and warm gently over low heat.
