Mushroom Gratin with Dijon Cream

How to make it

1. Pat the mushroom 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 mushroom until deeply colored.
3. Add the aromatics with the fingerling potatoes and carrots; cook until fragrant and just tender.
4. Build the dijon cream 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.
