Ratatouille Tart

I made a double cornmeal crust for this and even after baking it twice, once for the crust and again with the assembled tart, the crust did not hold up too well to slicing. Some potluck guests had suggested that instead of it being the crust, to use the cornmeal as a topping on top of the crust. That would be an interesting notion. I'll have to think about how to make it so that it cuts well and is crust-less. It is entirely doable if the bottom layer is comprised of sturdier slices of vegetables like more overlapping layers of eggplant and zucchini. This tart only had a single layer of roasted eggplant, zucchini and tomato slices. Without the 1/4" cornmeal crust it can easily accommodate more layers of vegetables. The inclusion of the shredded Gruyere and Swiss cheese into one of the cheese layers was certainly worth repeating. The original Food Network recipe only called for shredded mozzarella cheese, and three ounces was not enough for a 10" tart. I don't think it would be enough had I used a 9" tart pan.

For roasting:

1 green zucchini
1 Japanese eggplant (the long, thin one)
3 medium tomatoes
2 tbsp olive oil
kosher salt, to taste
freshly ground black pepper, to taste

Slice vegetables into 1/8" slices and lay out in a single layer on a 9" x 13" glass baking dish (for easier cleaning) or onto a Silpat-lined baking tray. Preheat oven to 400 degrees F and bake vegetables for 12 minutes. The vegetables should be soft and doesn't have to be cooked all the way through. Take roasted vegetables out and set aside to cool until ready to fill the tart pan.

The cornmeal crust (optional):

One batch will supposedly fill a 9" tart pan with a removable bottom. But, that is not the size I had on hand. I made a double batch and packed it all into the 10" tart pan, which turned out to be way too much crust.

2/3 c. finely ground white cornmeal
1/3 c. whole wheat flour
1 tsp dried rosemary
2 tbsp unsalted butter, cut into chunks
2 tbsp olive oil
1/4 tsp kosher salt

In a food prep, pulse together dry ingredients, then add butter and pulse until coarse crumbs form. Add in the olive oil and pulse until well combined.

If you managed to roast the vegetables first, turn the heat down to 350 degrees F. After packing the crust into the tart pan with a 1/4" edge around the base of the tart. Place a sheet of aluminum foil between the top of the tart and the pie weights. Bake for 10 minutes. Remove the aluminum foil and pie weights and bake for an additional 5 minutes or until the crust no longer looks shiny.

Kitchen note: this crust did not hold together and tasted very dry. The combination of olive oil and butter did not do much as a binder. Perhaps just a water, butter, flour crust would have sufficed.

Putting it all together:

The remaining ingredients for this recipe involves shredded cheese, sliced basil leaves, and grated Parmesan cheese (or some comparable tasting hard cheese).

3 oz - 5 oz mozzarella cheese, shredded
4 oz Gruyere and Swiss blend cheese, shredded
5 medium fresh basil leaves, sliced
1/4 c. grated Parmigiano-regianno cheese

Bottom layer:  roasted eggplant slices and mozzarella cheese. When I did this, I placed the slices in a circular manner with the slices slightly overlapping each other.

Middle layer: zucchini slices and Gruyere and Swiss cheese

Top layer: tomato slices, fresh basil leaf slices, and the remainder of the mozzarella cheese. Generously scatter the grated hard cheese on top of the tart.

Bake tart for 30 minutes, or until all the cheese has melted. It will smell a lot like a pizza because it is made up of similar ingredients.

Remove tart from oven and let cool before serving.
