Step 1: Prepare Your Ingredients (Mise en Place)

Before you turn on the heat, have everything prepped and ready to go. This makes the cooking process smooth and enjoyable.

1. Prep the Salmon: Pat the skinless salmon fillets dry with a paper towel. Cut them into generous 1-inch cubes. Season lightly with salt and pepper and set aside in the refrigerator while you prepare the base.

2. Prep the Vegetables: Thoroughly wash the leeks to remove all sand and grit, then thinly slice the white and light green parts. Finely chop the celery, dice the carrots and potatoes, and mince the garlic.

3. Prep the Herbs: Chop the fresh dill and parsley.

Step 2: Build the Aromatic Base

This is where the deep, foundational flavors of the stew are created.

1. Sauté the Vegetables: In a large Dutch oven or heavy-bottomed pot, melt the butter with the olive oil over medium heat. Add the sliced leeks, chopped celery, and diced carrots. Sauté for 8-10 minutes, stirring occasionally, until the vegetables have softened significantly and the leeks are translucent. This slow sauté builds sweetness.

2. Add the Garlic: Add the minced garlic and cook for another minute until fragrant. Be careful not to let it burn.

Step 3: Create the Roux and Deglaze

This step thickens the stew and adds another layer of flavor.

1. Thicken with Flour: Sprinkle the all-purpose flour over the softened vegetables. Stir constantly for about 2 minutes to cook out the raw flour taste. The mixture will become a thick paste.

2. Deglaze with Wine: Pour in the dry white wine. As it bubbles, use a wooden spoon or spatula to scrape up all the browned bits (the fond) from the bottom of the pot. These bits are packed with flavor. Let the wine cook down and reduce by about half.

Step 4: Simmer the Stew Base

Now it’s time to create the broth and cook the potatoes until they are perfectly tender.

1. Add Liquids and Seasoning: Gradually whisk in the chicken or vegetable broth, a little at a time, to ensure the flour mixture dissolves smoothly without lumps. Add the diced potatoes, the bay leaf, 1 teaspoon of salt, and 1/2 teaspoon of black pepper.

2. Simmer: Bring the mixture to a gentle boil, then reduce the heat to low, cover the pot, and let it simmer for 15-20 minutes, or until the potatoes are completely tender when pierced with a fork.

Step 5: Add the Cream and Salmon

This is the final cooking stage. It’s important to be gentle here to keep the salmon tender.

1. Temper the Cream: Reduce the heat to the lowest possible setting. Slowly pour in the heavy cream, stirring gently to combine. It’s important not to let the stew boil after adding the cream, as it could curdle.

2. Cook the Salmon: Gently add the cubed salmon to the hot stew. Stir once to submerge the pieces. Let the salmon poach gently in the hot broth for just 3-5 minutes. The salmon is done when it is opaque and flakes easily with a fork. Do not overcook it, or it will become tough.

Step 6: Finish with Freshness

These final additions will elevate your stew from great to absolutely exceptional.

1. Add Herbs and Lemon: Remove the pot from the heat. Discard the bay leaf. Gently stir in the chopped fresh dill, fresh parsley, and the fresh lemon juice.

2. Taste and Adjust: Taste the stew and adjust the seasoning as needed with more salt, pepper, or lemon juice. Let the stew rest for 5-10 minutes off the heat for the flavors to meld together perfectly before serving.
