Buttermilk-Poached Salmon Ingredients

For the Salmon

  • Salmon Fillet – Choose skinless fillets for a tender bite without the hassle of removing skin.

For the Poaching Liquid

  • Buttermilk – This creamy base not only poaches the fish but also adds a slight tang. Opt for full-fat for the best results.
  • Vegetable Broth – Use low-sodium broth to enrich the flavor while keeping the dish healthy.
  • Shallot – Infuse the poaching liquid with a mild, sweet flavor; if unavailable, onion can be a suitable substitute.
  • Garlic – Elevates the dish’s flavor; garlic powder works in a pinch if fresh is not handy.
  • Lemon – Provides a bright acidity; ensure you slice it and remove the seeds for a cleaner taste.
  • Fresh Thyme – This aromatic herb enhances the overall flavor; feel free to use dried thyme if fresh is out of reach.
  • Bay Leaves – Optional but recommended for a subtle depth in the poaching liquid.
  • Dijon Mustard – Adds richness to the poaching liquid; you might swap it for whole grain mustard for a different texture.

For the Finish

  • Kosher Salt – Essential for seasoning the salmon and enhancing all the flavors.

Step‑by‑Step Instructions for Buttermilk-Poached Salmon

Step 1: Prepare Ingredients
Begin by prepping your ingredients for the Buttermilk-Poached Salmon. Peel and halve the shallot, then lightly smash the garlic cloves to release their flavor. Next, slice the lemon, ensuring to remove any seeds, and gather fresh thyme and bay leaves, preparing them for the poaching process.

Step 2: Season Salmon
Sprinkle kosher salt generously over both sides of the salmon fillet, allowing it to absorb the flavor. This step not only enhances the taste but also helps firm up the fish’s texture during poaching. Set the seasoned salmon aside while you prepare the poaching liquid.

Step 3: Combine in Skillet
In a large skillet, arrange the salmon fillet at the center. Pour in the buttermilk and vegetable broth until the fish is well-covered. Add the prepared shallot, smashed garlic, fresh thyme, bay leaves, and lemon slices to the skillet. This aromatic medley sets the stage for your flavorful poaching liquid.

Step 4: Heat
Place the skillet over medium heat and bring the mixture to a gentle simmer. Once it reaches a simmer, reduce the heat to low, maintaining a gentle simmer for about 11-12 minutes. As it cooks, the salmon will turn opaque and flake easily, signaling it’s ready to be removed from the heat.

Step 5: Rest
Once the salmon has finished cooking, remove the skillet from the heat and cover it with a lid. Let the salmon rest in the residual heat for about 5 minutes. This resting period helps the flavors meld and ensures the fish remains tender and moist.

Step 6: Serve
Carefully transfer the salmon fillet to a plate once rested. Strain the poaching liquid into a saucepan and add Dijon mustard. Heat it over medium flame, gently whisking until the mixture has reduced by half and becomes creamy and milky. Drizzle this luxurious sauce over the salmon before serving for a delightful finish.

How to Store and Freeze Buttermilk-Poached Salmon

Fridge: Store leftover Buttermilk-Poached Salmon in an airtight container for up to 2 days. Keep the poaching liquid separate to preserve freshness and prevent sogginess.

Freezer: If you want to extend the shelf life, freeze the salmon individually wrapped in plastic wrap and aluminum foil for up to 3 months. Thaw in the refrigerator before reheating.

Reheating: Gently reheat the salmon in a preheated oven at 350°F (175°C) for about 10 minutes, or until warmed through. Avoid microwaving to maintain its tender texture.

Accompaniments: Serve the reheated salmon with fresh herbs, a squeeze of lemon, or the reserved poaching liquid for enhanced flavor upon serving.

Buttermilk-Poached Salmon Variations

Feel free to get creative and make this Buttermilk-Poached Salmon your own with these delightful twists!

  • Herb Change-Up: Use dill or parsley instead of thyme for a fresh herbal note that pairs beautifully with fish.

  • Spicy Kick: Add a pinch of red pepper flakes to the poaching liquid for a gentle heat that warms each bite.

  • Citrus Zest: Incorporate lime or orange zest into the poaching liquid; this brightens the dish with a lovely citrusy fragrance.

Buttermilk-Poached Salmon Recipe FAQs

What should I look for when selecting salmon?
When choosing salmon fillets, look for bright, vibrant colors and a fresh, slightly sweet aroma without any fishy smell. The flesh should appear moist, and if it’s skinless, there should be no dark spots all over. Always opt for wild-caught if available, as it tends to have a better flavor and texture!

How should I store leftovers from Buttermilk-Poached Salmon?
Leftover Buttermilk-Poached Salmon can be stored in an airtight container in the refrigerator for up to 2 days. To keep it fresh, keep the poaching liquid separate from the salmon until you’re ready to enjoy it again. This helps prevent the fish from getting soggy!

Can I freeze Buttermilk-Poached Salmon?
Absolutely! To freeze, wrap the individual salmon portions in plastic wrap, then in aluminum foil, or place them in a freezer-safe bag for up to 3 months. When ready to enjoy, thaw the salmon in the refrigerator overnight before gently reheating it.

What should I do if my buttermilk curdles while poaching?
A little curdling is perfectly normal when poaching in buttermilk; don’t panic! Just strain the poaching liquid through a fine sieve after cooking to remove any curds. The resulting sauce will still be creamy and delicious, enhancing the dish beautifully.

Is this recipe suitable for people with allergies?
This Buttermilk-Poached Salmon recipe contains dairy (buttermilk) and mustard. If you’re allergic to dairy, consider substituting buttermilk with a non-dairy milk mixed with a splash of lemon juice or vinegar for acidity. Always check ingredient labels for allergies, particularly with broths or mustard.

Can I use different herbs or fish for this recipe?
Very! Feel free to swap the salmon with other fish like trout or cod, which poach beautifully as well. As for herbs, dill or parsley offers a lovely twist instead of thyme. Experimenting with different flavors can make the dish your own!
