Salade Nicoise Slab Tart! In Partnership with Maille and Silpat

It's funny how refinement of a palate can mean embracing the more rustic side to food. When I first began cooking, I thought that French food was a paradigm to strive towards. I realized that the food I still loved most was uncut edges and cracked tops. In some ways, it's a lack of stress in baking, a lackadaisical approach to the homemade that still intrigues me. It's the extra butter, the egg wash that tans, and the layers of hearty flavors that I gravitate more towards.

Recipes like this are more my style, and I learned that through the trial and error of hubris and pretension when it comes to cooking.

I look to the Midwestern casseroles my mother made, how economical and in different shades of cheddar cheese and golden potatoes. I think of how they stayed on the oven top to be picked at throughout the day with fingertips and by the forkful. I think about how natural it was to look at food for how it felt and not what it always looked like. If that was a lesson my mother taught me, it was in the space between conscious need and survival instinct: get dinner on the table and get laundry done and go to sleep for tomorrow.

So I've taken what came so natural to me and added a few French elements and came up with this tart - cracked and rustic and good throughout the day. With the help of Maille and Silpat, it was an instant hint when the in-laws came over to help with yard work this weekend and I remember how far we've come together, my partner and I.

• 2 medium-sized Yukon Gold or similar potato
• 15-20 green beans
• 2 eggs + 1 for egg wash
• 1/4 cup oil
• 1/2 TB lemon zest
