Ingredients

Instructions

  1. Step 1: Pat 4 trout filets dry and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 3 tbsp olive oil in a large nonstick skillet over medium-high heat.
  2. Step 2: Place the filets skin-side down in the hot skillet and sear for 4 minutes until the skin is crisp and golden. Flip and cook for another 2-3 minutes until the flesh is opaque and flakes easily.
  3. Step 3: In a small bowl, whisk together 2 tbsp Dijon mustard, 1/4 cup Greek yogurt, 1 tbsp lemon juice, 2 tbsp chopped fresh dill, and 1 minced garlic clove until smooth and creamy.
  4. Step 4: Serve the trout filets immediately topped with the mustard-dill sauce while still warm.

Frequently asked questions

How long does Pan-Seared Trout with Mustard-Dill Sauce take to make?

Total time is about 20 minutes (10 min prep + 10 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Pan-Seared Trout with Mustard-Dill Sauce?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep (6 oz each) trout filets from drying out.

Can I substitute ingredients in Pan-Seared Trout with Mustard-Dill Sauce?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Pan-Seared Trout with Mustard-Dill Sauce for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Pan-Seared Trout with Mustard-Dill Sauce?

Mediterranean seafood like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
