Step‑by‑Step Instructions for Buttermilk-Poached Salmon

Step 1: Prepare the Aromatics
Begin by peeling and halving the medium shallot lengthwise, then smash the two garlic cloves with the flat side of a knife to release their flavor. Thinly slice the lemon into rounds and set aside. These ingredients will enhance the poaching liquid of your buttermilk-poached salmon, providing a fragrant foundation for the dish.

Step 2: Season the Salmon
Generously season both sides of the skinless salmon fillet with kosher salt, allowing it to absorb the flavor. Place the salmon in a large skillet or pot, making sure it fits comfortably without crowding. This setup will enable even cooking as the salmon poaches in the rich and creamy buttermilk mixture.

Step 3: Combine the Poaching Liquid
Pour the full-fat buttermilk and low-sodium vegetable broth into the skillet, ensuring the salmon is submerged. Add the shallots, smashed garlic, lemon slices, fresh thyme sprigs, and bay leaves on top of the fish. This mixture creates a delightful poaching liquid that will infuse your salmon with a tangy, herbaceous taste while keeping it tender.

Step 4: Start Poaching
Set your skillet over medium heat and bring the liquid to a gentle simmer. Once you see small bubbles appearing, reduce the heat to low to maintain a steady warm temperature. Allow the salmon to poach quietly for 11 to 12 minutes, or until it becomes opaque and firm, signaling that it is perfectly cooked.

Step 5: Remove the Salmon
Carefully lift the salmon fillet out of the poaching liquid using a slotted spatula, letting excess liquid drain off. Transfer the poached salmon to a serving plate and set it aside, allowing it to rest while you prepare the sauce. The salmon should look moist and flaky, demonstrating the effectiveness of the buttermilk poaching technique.

Step 6: Prepare the Sauce
Stir in the Dijon mustard into the remaining poaching liquid, bringing it back to a simmer over medium-low heat. Let it cook for about 9 to 11 minutes, or until the sauce has reduced by half, thickening slightly to enhance the richness of your dish. This sauce will add an extra layer of flavor to your buttermilk-poached salmon.

Step 7: Strain and Serve
Once reduced, strain the sauce through a fine mesh sieve into a bowl, discarding the solids. Drizzle this smooth, flavorful sauce over the poached salmon on your serving plate. With the tender fish and creamy, tangy sauce, your buttermilk-poached salmon is now ready to delight your family or guests!

Variations & Substitutions for Buttermilk-Poached Salmon

Customize your buttermilk-poached salmon to match your taste preferences and dietary needs for a delightful twist!

Dairy-Free: Substitute full-fat buttermilk with a plant-based milk mixed with lemon juice for a similar tang. Your dish will still retain that creamy texture!
Spicy Kick: Add a dash of cayenne pepper or red pepper flakes to the poaching liquid for a little heat. This will elevate the flavor profile, making it exciting and zesty!
Herbal Infusion: Try fresh dill or tarragon in place of thyme for a different herbal finish. The unique flavors will create a new culinary experience, while still being incredibly savory.
Citrus Variety: Swap the lemon for orange or grapefruit slices for a surprising sweetness in the dish. This fruity twist will lighten the overall flavor and complement the salmon beautifully.
Texture Up: Top your finished salmon with toasted nuts like almonds or walnuts for added crunch. It’s a delightful contrast to the tender poached fish, making every bite satisfying!
Umami Boost: Incorporate a tablespoon of miso paste into the poaching liquid for a deeper flavor profile. It’s an easy way to add complexity, making the dish richer in taste!
Creamy Sauce Upgrade: Mix in a splash of cream to the reduced poaching liquid for a richer, silkier sauce. The creamy finish promises to coat the salmon perfectly, enhancing each mouthful.

Make Ahead Options

These Buttermilk-Poached Salmon fillets are perfect for meal prep enthusiasts looking to save time during busy weekdays! You can poach the salmon up to 2 days in advance; simply store the salmon in its poaching liquid in an airtight container in the refrigerator to maintain its moisture and flavor. To serve, gently reheat the salmon in the poaching liquid over low heat to avoid overcooking. The sauce can also be prepared ahead by straining it and refrigerating it separately. This way, when you’re ready to enjoy your meal, simply reheat the sauce and drizzle it over the salmon for restaurant-quality results with minimal effort!

Helpful Tricks for Buttermilk-Poached Salmon

Watch the Heat: Keep your poaching liquid at a gentle simmer. High heat can overcook the salmon, leading to a dry texture.
Curdling is Normal: If the buttermilk curdles while cooking, don’t fret! It’s standard during poaching and strains out nicely afterwards.
Fresh Ingredients Matter: Opt for the freshest skinless salmon fillet you can find. Fresh fish not only tastes better but also enhances the buttermilk-poached salmon experience.
Don’t Skip the Herbs: Fresh thyme adds a delightful aroma; if you use dried thyme, reduce the amount to avoid overpowering the dish.
Let it Rest: Allow the salmon to rest for a minute after poaching. This helps retain moisture and ensures a tender, flaky finish.

How to Store and Freeze Buttermilk-Poached Salmon

Room Temperature: Avoid leaving the salmon out at room temperature for more than 2 hours to ensure food safety and quality.

Fridge: Store leftover buttermilk-poached salmon in an airtight container for up to 2 days, ideally keeping it in the poaching liquid to retain moisture.

Freezer: For longer storage, freeze the salmon in a freezer-safe container or wrap tightly in plastic wrap. It can last up to 2 months, but may lose some quality after thawing.

Reheating: When you’re ready to enjoy leftovers, reheat gently in the microwave or on the stovetop over low heat to keep the salmon tender and prevent drying out.

Buttermilk-Poached Salmon Recipe FAQs

How do I choose the best salmon for this recipe?
Absolutely! Look for skinless salmon fillets that are bright pink with a moist, shiny surface. The flesh should feel firm to the touch, and avoid any that have dark spots or a fishy smell. Freshness is key, so don’t hesitate to ask your fishmonger about the sourcing to ensure top quality for your buttermilk-poached salmon.

How can I store leftover buttermilk-poached salmon?
Very simply! Place the leftover salmon in an airtight container and store it in the refrigerator for up to 2 days. I recommend keeping it in the poaching liquid as this helps retain the salmon’s moisture and flavor. Just remember to let it cool down to room temperature before putting it in the fridge.

Can I freeze buttermilk-poached salmon?
Absolutely! To freeze, wrap the cooled salmon tightly in plastic wrap, then place it in a freezer-safe container or a resealable bag, pushing out as much air as possible. It’ll last up to 2 months in the freezer. When you’re ready to enjoy it again, thaw it in the refrigerator overnight and gently reheat it to maintain its tenderness.

What if my buttermilk curdles during cooking?
Don’t worry at all! A little curdling is normal when poaching in buttermilk, and it straining out is easy. If you encounter this, simply continue to simmer the poaching liquid until it mostly reduces and thickens. The flavors will still meld beautifully, so go ahead and enjoy your meal!

Is this recipe suitable for people with dairy allergies?
No need to miss out! While buttermilk provides a unique flavor and texture, you can substitute it with a dairy-free version. Try using a non-dairy milk like almond or soy mixed with a splash of lemon juice or vinegar to achieve a similar tang and maintain the poaching effect for your buttermilk-poached salmon.

Can I make this dish in advance?
Certainly! You can poach the salmon a day or two ahead of time. Just keep the salmon and sauce in separate airtight containers until you’re ready to serve. This makes mealtime easier and allows the flavors to develop further. Just remember to reheat gently so it stays moist and delicious!
