Shopping List
- 4 trout fillets (about 5–6 ounces each), skin-on if possible
- 12 ounces fresh green beans, trimmed
- 2 lemons (zest and juice)
- 2–3 tablespoons olive oil
- 2 tablespoons unsalted butter
- 2 teaspoons lemon pepper seasoning (or more to taste)
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper (if your lemon pepper seasoning is mild)
- 2 garlic cloves, minced
- 1/4 teaspoon red pepper flakes (optional)
- Fresh parsley or chives, chopped (optional, for garnish)
- Lemon wedges, for serving
How to Make It
- Pat the trout dry. Use paper towels to remove surface moisture. This helps you get a good sear and prevents sticking.
- Season the fillets. Sprinkle both sides with lemon pepper seasoning and kosher salt.
If your lemon pepper blend is mild, add a little extra black pepper.
- Blanch the green beans (optional but helpful). Boil salted water, add beans for 2–3 minutes until bright green, then drain and rinse with cold water. This jump-starts the cooking and keeps them crisp-tender.
- Heat the pan. Set a large skillet over medium-high heat. Add 1–2 tablespoons olive oil and let it shimmer.
- Sear the trout, skin-side down first. Place fillets in the pan without crowding.
Press gently with a spatula for the first 20–30 seconds to keep the skin flat. Cook 2–3 minutes, then flip and cook another 1–2 minutes, depending on thickness. Trout should flake easily but remain moist.
- Add butter and lemon. Reduce heat to medium.
Add 1 tablespoon butter to the pan, along with the zest of 1 lemon and a squeeze of lemon juice. Spoon the buttery lemon over the fish for 30 seconds. Transfer trout to a warm plate and tent loosely with foil.
- Sauté the green beans. In the same pan, add another drizzle of olive oil if needed, plus the remaining butter.
Add garlic and red pepper flakes; cook 20–30 seconds until fragrant. Add the green beans, a pinch of salt, and toss for 3–4 minutes until glossy and tender-crisp.
- Finish with brightness. Zest the second lemon over the beans, squeeze in more juice to taste, and toss. Adjust seasoning with salt and pepper.
- Plate and serve. Arrange trout over or beside the green beans.
Spoon any pan juices on top. Garnish with herbs and serve with extra lemon wedges.
Storage Instructions
- Refrigerate: Store leftover trout and green beans in separate airtight containers for up to 2 days.
- Reheat gently: Warm the trout low and slow—either in a 275°F (135°C) oven for 8–10 minutes or in a covered skillet over low heat with a splash of water. Avoid microwaving at high power to keep it from drying out.
- Freeze: Trout can be frozen up to 2 months, but texture may soften.
Green beans are best eaten fresh.
Health Benefits
- Lean protein: Trout offers high-quality protein to keep you full and support muscle health.
- Omega-3 fats: Trout contains heart-friendly fats that support brain and cardiovascular health.
- Vitamins and minerals: You get B vitamins from fish and vitamin C from lemon, plus potassium and fiber from green beans.
- Light on calories: The recipe uses modest oil and butter for flavor without overloading on heaviness.
- Gluten-free by default: No flour or breadcrumbs needed, making it an easy fit for many diets.
Pitfalls to Watch Out For
- Overcooking the fish: Trout cooks fast. Pull it as soon as it flakes and looks slightly translucent in the center.
- Soggy skin: For crisp skin, start with a very dry fillet, a hot pan, and avoid moving the fish for the first minute.
- Too much lemon too soon: Adding lots of juice early can steam the fish. Finish with citrus and adjust to taste at the end.
- Underseasoned beans: Green beans need salt and a little fat.
Taste and tweak before serving.
- Burning the garlic: Add garlic after the butter melts and keep the heat moderate. Burnt garlic turns bitter fast.
Recipe Variations
- Sheet pan style: Roast trout and green beans on a lined sheet at 425°F (220°C). Toss beans with oil, salt, and pepper; roast 10 minutes.
Add seasoned trout to the pan and roast 8–10 minutes more. Finish with lemon-butter.
- Herb-forward: Add chopped dill, parsley, or tarragon to the butter. A teaspoon of capers brings briny pop.
- Garlic-lemon panko: For a crunchy topping, mix 1/2 cup panko with olive oil, lemon zest, and a pinch of salt.
Toast in a skillet and sprinkle over the plated fish.
- Spicy citrus: Swap red pepper flakes for Aleppo pepper or add a touch of hot honey to the beans for sweet heat.
- Dairy-free: Skip butter and finish with extra-virgin olive oil for a bright, clean finish.
- Grilled trout: Oil the grates well. Grill skin-side down over medium heat 3–4 minutes, then flip for 1–2 minutes. Toss beans in a grill basket.
FAQ
Can I use frozen trout?
Yes.
Thaw it overnight in the fridge, then pat very dry before cooking. Frozen fish can release extra moisture, so take your time drying it for a better sear.
What can I use instead of trout?
Arctic char, steelhead trout, or salmon are great swaps. Thin white fish like tilapia or sole also work but cook even faster, so reduce the time.
Do I have to blanch the beans?
No.
You can sauté them directly. They’ll just take a couple more minutes to reach tender-crisp. Taste as you go and season well.
How do I know when the trout is done?
The flesh should flake easily and look opaque with a slight translucence in the center.
If you use a thermometer, aim for 125–130°F (52–54°C) for moist, tender fish.
Is lemon pepper seasoning necessary?
It’s convenient, but you can make your own. Combine lemon zest, freshly ground black pepper, a pinch of garlic powder, and kosher salt. Add a touch of sugar if you like a rounder flavor.
In Conclusion
Lemon pepper trout with green beans delivers bright flavor, crisp textures, and a low-stress cooking process.
It’s fast enough for a weeknight but fresh and pretty enough for company. Keep a couple of fillets in the fridge, a bag of green beans on hand, and a lemon or two on the counter. With those basics, you can put a satisfying, wholesome dinner on the table any night of the week.
