Ingredients (4 servings)

Trout & Seasoning

4 whole rainbow trout (¾–1 lb each), gutted, scaled, and cleaned
2 tbsp olive oil
1½ tsp kosher salt
½ tsp freshly cracked black pepper

Aromatic Stuffing

2 lemons (1 thinly sliced, 1 cut into wedges for serving)
8–12 sprigs fresh dill (or thyme, parsley, tarragon)
8 cloves garlic, smashed
1 small shallot or red onion, thinly sliced

Optional Butter Finish

2 tbsp unsalted butter, melted
Pinch red pepper flakes or smoked paprika

Garnish

Fresh dill, parsley, lemon wedges

Essential Tools and Equipment

Large rimmed baking sheet
Parchment paper or foil
Sharp knife for scoring (optional)

Step-by-step process

Preheat oven to 450 °F (230 °C) with rack in upper third. Line a baking sheet with parchment.
Prep trout — pat fish completely dry inside and out. Score skin 3–4 times per side (helps seasoning penetrate). Rub inside and out with olive oil, salt, and pepper.
Stuff — place 2–3 lemon slices, 2–3 dill sprigs, 2 garlic cloves, and a few shallot slices in each cavity.
Arrange — lay trout on a baking sheet without crowding.
Bake 12–18 minutes (12 min per inch of thickness) — flesh turns opaque and flakes easily; skin will blister and crisp. No flipping needed.
Optional butter baste — last 2 minutes, brush with melted butter + paprika for extra golden glow.
Rest 3 minutes → serve whole or fillet tableside with extra lemon wedges.

Mistakes to avoid

Wet fish — soggy skin; pat aggressively dry.
Low oven — no crispy skin; 450 °F minimum.
Overcooking — pull at 135–140 °F internal; carryover brings to 145 °F.
Skipping scoring — seasoning stays on the surface only.
Crowding pan — steams instead of roasts.

Variations of the Best Baked Rainbow Trout

Mediterranean — stuff with tomatoes, olives, and feta.
Cajun Blackened — heavy Cajun spice + butter baste.
Asian — ginger, scallions, soy-sesame glaze last 2 min.
Almondine — top with toasted almonds + lemon butter after baking.
Fillets — same method, 8–10 min total.

Tips for better storage & make-ahead

Leftovers — fridge up to 2 days; flake cold into salads or tacos.
Reheating — 275°F 8–10 min to gently warm without drying.
Freezer — whole raw trout freezes beautifully up to 3 months.

Strong fish taste? Fresh rainbow trout is mild — soak in milk for 20 minutes if worried.
Grill version? Same stuffing → 6–8 min per side over medium-high.
