Ingredients

Instructions

  1. Step 1: In a medium bowl, whisk together 1 cup all-purpose flour, 2 large eggs, 1/3 cup milk, and 1/2 tsp salt to form a sticky batter. Let rest 10 minutes.
  2. Step 2: Bring a large pot of salted water to a rolling boil. Using a spätzle maker or colander with large holes, press the batter into boiling water. Cook spätzle for 2-3 minutes until they float, then remove with a slotted spoon and drain.
  3. Step 3: Heat 3 tbsp unsalted butter and 2 tbsp olive oil in a large skillet over medium heat. Add 4 trout fillets skin-side down, seasoning with 1/2 tsp salt and 1/2 tsp black pepper. Cook 4-5 minutes until skin is crisp, flip carefully and cook 2 more minutes until opaque.
  4. Step 4: In a separate pan, melt remaining 3 tbsp unsalted butter over medium heat. Stir in 2 tbsp chopped fresh parsley and 1 tbsp chopped fresh chives, then toss the cooked spätzle in the herb butter until coated and heated through.
  5. Step 5: Plate the trout fillets atop the buttery spätzle and serve with lemon wedges on the side.

Frequently asked questions

How long does Pan-Seared Trout with Herb Butter and Spätzle take to make?

Total time is about 40 minutes (20 min prep + 20 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 Herb Butter and Spätzle?

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 (5 oz each) trout fillets from drying out.

Can I substitute ingredients in Pan-Seared Trout with Herb Butter and Spätzle?

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 Herb Butter and Spätzle 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.
