Dinner in 30 · American
One Pan Lemon Herb Salmon
This is my favorite kind of dinner: the oven does the work and I do the standing around part. Salmon fillets and green beans roast on one sheet pan with lemon, garlic, and dried herbs, and 25 minutes after you start, dinner is on the table.
The beans get a 6 minute head start in the oven so they finish at the same time as the fish. Without that head start you end up with perfectly cooked salmon next to squeaky green beans, and nobody wants that trade.
Everything in this recipe is naturally gluten free and dairy free, no swaps, no label hunting. About 390 calories a serving, with around 30 grams of protein from the salmon.

Why you will love it
25 minutes total, and most of it is hands off while the oven runs.
One sheet pan, and the parchment means cleanup takes two seconds.
Gluten free and dairy free as written, nothing to swap or substitute.
The lemon rounds roast right onto the fish, so it tastes bright instead of heavy.
About 30 grams of protein per serving for around 390 calories.
Tips
Use parchment, not just for cleanup. Salmon skin glues itself to a bare pan.
Do not skip the 6 minute head start for the beans, or you get raw crunchy beans with perfect fish.
Check the salmon at 12 minutes. Thick center fillets take 14, skinny tail pieces take 11.
Pull the fish at 145 F (63 C) and not a degree more. Salmon carries on cooking a little as it sits.
Swaps and variations
Fresh herbs: use 1 tbsp chopped fresh dill stirred in with the lemon juice at the end, and skip the dried oregano and thyme. What changes: a brighter, greener flavor.
Cod instead of salmon: roast the same way. What changes: cod fillets are thinner, so check at 10 minutes, and it is leaner and milder, still done at 145 F (63 C).
Broccoli instead of green beans: cut small florets and give them the full 6 minute head start. What changes: a heartier vegetable with more bite at the end.
What to serve
Steamed white rice, with the pan juices and lemon poured over everything.
Crusty bread to wipe the pan clean.
A cold cucumber salad with vinegar, which takes five minutes and balances the warm fish.
Storage and reheating
Leftovers keep in the fridge for 3 days. Honest note: salmon tastes brightest the day it is cooked, and it dries out when reheated. When I reheat it, I use a 300 F (150 C) oven for about 10 minutes, until it reaches 165 F (74 C), and I accept that it will be more cooked than it was fresh. Some nights I skip the reheating and flake the cold salmon over a salad instead, which is honestly the better move. The beans reheat fine in a hot skillet, 2 to 3 minutes. You can freeze the salmon up to 2 months, but the texture comes back softer.

Questions cooks actually ask
Can I use frozen salmon fillets?
Yes, but thaw them overnight in the fridge first and pat them very dry. What changes: nothing else, except wet fillets steam instead of roast, so the drying step matters even more with thawed fish.
Can I use frozen green beans?
You can, but thaw them and pat them very dry, and spread them out with space. What changes: they come out softer and less blistered than fresh beans, still perfectly fine for a Tuesday.
How do I know the salmon is done without a thermometer?
Two cues: the flesh turns opaque all the way to the top, and it flakes apart when you press it with a fork at the thickest point. If it still looks translucent and glossy, give it 2 more minutes. A thermometer reading 145 F (63 C) is the sure answer if you have one.
Do I eat the skin?
It is edible, but roasted skin side down on parchment it goes soft rather than crisp. Lift the fillet off with a spatula and leave the skin behind on the paper if you would rather skip it.
