Pesto Salmon
The story
Pesto and salmon are both rich in the same direction, which is why most versions of this pairing come out heavy. The fix is not less pesto. The fix is acid and heat: blistered tomatoes that burst into something jammy and sharp, a squeeze of lemon at the end, and a hot oven that crisps the pesto crust on top of the fillet rather than letting it sit there as a green paste.
The crust is the technique. Pesto spread on salmon and roasted at high heat dries at the surface and toasts the parmesan and pine nuts in it, so you get a savory crust rather than a sauce. Underneath, the fish stays at medium and releases its oil. That oil has to go somewhere, and a District Biscuit is the rare base that treats salmon fat as an asset. Its own laminated butter means oil reinforces rather than saturates, and the crisp edges hold while the layers take it in.
That is the culinary canvas doing weeknight elegance. Thirty minutes, one sheet pan, and a plate that looks considerably more considered than the effort behind it.
Why you'll love it
- Roasting the pesto creates a toasted crust rather than leaving a green sauce on top.
- The District Biscuit treats salmon oil as reinforcement instead of getting saturated by it.
- Blistered tomatoes bring the acid that keeps pesto and salmon from doubling up on richness.
- One sheet pan, thirty minutes, and about five minutes of actual work.
- High in protein and omega-3s while still eating like an indulgence.
Ingredients
- 4 District Biscuits, warmed and split
- 4 salmon fillets, about 6 oz each, skin removed
- 3/4 cup basil pesto, store-bought or homemade
- 2 cups cherry tomatoes
- 2 tbsp olive oil
- 1 lemon, half juiced and half cut into wedges
- 1/4 cup grated parmesan
- 2 cups baby arugula
- 1 clove garlic, minced
- Flaky salt and black pepper
How to build it
-
1
Heat the oven to 425F and line a sheet pan with parchment.
-
2
Pat the salmon fillets completely dry and season them lightly with salt and pepper on all sides.
-
3
Spread the pesto thickly over the top and sides of each fillet, then scatter the grated parmesan over the pesto so it toasts into a crust.
-
4
Toss the cherry tomatoes with the olive oil, minced garlic, and a pinch of salt, then spread them around the fillets on the pan.
-
5
Roast for 12 to 14 minutes until the pesto crust darkens at the edges, the tomatoes burst, and the salmon reaches 125F at the thickest point.
-
6
Warm the District Biscuits in a 350F oven for the last 5 minutes and split them so the layers are open.
-
7
Rest the salmon for 3 minutes so the flakes set, and toss the arugula with lemon juice and a pinch of salt.
-
8
Set a fillet on each biscuit bottom, spoon the blistered tomatoes and their pan juices over the top, add dressed arugula and flaky salt, cap, and serve with lemon wedges.
Pro tips & swaps
- Dry the salmon before the pesto goes on. Surface moisture steams under the crust and prevents it from toasting.
- Parmesan over the pesto, not mixed into it. On top it browns, mixed in it just melts.
- Pull the salmon at 125F. It climbs while resting, and salmon taken to visibly well done in the oven is already past it.
- The tomato pan juices are the sauce. Spoon them onto the biscuit deliberately rather than leaving them on the pan.
- Swap salmon for arctic char or thick cod, reducing the roast to 10 minutes for cod since it is more delicate.

Frequently asked questions
Can I make the Pesto Salmon Biscuit ahead of time?
Pesto keeps 5 days refrigerated under a layer of oil, and the salmon can be portioned and pesto-coated a few hours ahead. Roast to order, since reheated salmon dries out quickly. Assemble on freshly warmed District Biscuits.
What's the best biscuit to use for a salmon sandwich?
A flaky, butter-laminated biscuit like a District Biscuit is ideal because salmon releases oil and pesto adds more. Ordinary bread goes greasy and translucent, while the District Biscuit's own butter content means the oil reads as richness.
Can I substitute the salmon in this recipe?
Yes. Arctic char and steelhead trout behave almost identically. Thick cod works with a shorter roast, and chicken breast takes the same pesto crust at about 20 minutes. **Is there a gluten-free or vegetarian version of the Pesto Salmon Biscuit?** For vegetarian, use thick planks of eggplant or halloumi with the same pesto crust. Check your pesto label, and note the District Biscuit is wheat-based, so check with the District Biscuit cafe about gluten-free options.
How do I know when salmon is done?
Pull it at 125F internal for medium, where it stays moist and flakes with slight resistance. It climbs a few degrees while resting. Without a thermometer, press the thickest part and look for flakes that separate but do not fall apart.
What should I serve or drink with a Pesto Salmon Biscuit?
Roasted asparagus, white beans dressed in lemon, or more of the arugula salad. For drinks, a Vermentino, a Sauvignon Blanc, or a dry rose.
How many calories are in a Pesto Salmon Biscuit?
A single build lands roughly in the 620 to 760 calorie range, driven by the salmon and the oil in the pesto. Reducing the pesto to half a cup brings it near 540.
How do I store and reheat leftovers?
Store the salmon and tomatoes separately for up to 2 days. Reheat the salmon gently at 275F for 8 minutes so it does not dry, and re-crisp the District Biscuit at 350F. Cold leftover pesto salmon flaked over greens also makes a very good next-day salad.
What makes a District Biscuit different from a regular biscuit?
District Biscuits are made with crisp, buttery edges and distinct flaky layers engineered to be a legit sandwich base, not just a side. That structure is why they hold up under oily builds like pesto and salmon where ordinary bread goes translucent. It is your culinary canvas, built to carry big flavor from first bite to last.
