Classic Salmon Gratin

How to make it

1. Pat the salmon dry and season well with salt, pepper, and a little of the spice mix.
2. Heat the butter in a dutch oven over medium-high and roast the salmon until deeply colored.
3. Add the aromatics with the carrots and tomatoes; cook until fragrant and just tender.
4. Build the herbes de provence sauce in the pan and simmer until it clings to everything.
5. Fold it back together, taste for salt, and finish with the fresh herbs.
