Ingredients
- 1 pkg. frozen artichoke hearts, thawed, drained, and larger ones cut in half
- 3-4 green onions, green part only, very thinly sliced
- 2 tsp. olive oil
- Salt and fresh ground black pepper to taste
- 1/4 cup whole wheat bread crumbs
- 1/3 cup grated Parmesan cheese
- 1/3 cup grated Pecorino-Romano cheese
- 1/2 tsp. dried thyme
- 1/4 tsp. dried oregano
- 1/3 cup mayo or light mayo
- Juice and zest of 1 lemon
- 1/2 tsp. garlic puree
Directions
- Heat the oven to 325F/170C. If the artichoke hearts are still frozen, thaw them in the microwave, then drain them thoroughly.
- Slice any larger artichoke hearts lengthwise so the pieces are fairly even. Rub 2 small gratin dishes or 1 medium sized baking dish with the olive oil. An 8.5 x 8.5 inch square baking dish works, as do 2 small 7 inch round gratin dishes.
- Spread the artichoke hearts out in the prepared dish in one layer. Scatter the very thin green onion slices over them, then add salt and freshly ground black pepper.
- In a bowl, combine the bread crumbs or almond meal, Parmesan, Pecorino-Romano, thyme, and oregano. If the grated cheese is on the coarse side, pulse it in a mini-processor for a minute or two to make it finer.
- In another bowl, whisk the mayo with the lemon juice, lemon zest, and garlic puree. Stir in 1/2 cup of the cheese mixture.
- With a rubber scraper, smooth the mayo mixture over the artichoke hearts. Save the remaining bread crumb and cheese mixture for the top.
- Cover the dish or dishes with foil and bake at 325F/170C for 30 minutes.
- Take the dish from the oven, then raise the heat to 375F/190C.
- Peel off the foil and scatter the reserved cheese mixture over each dish.
- Return to the oven and bake for about 25 minutes longer, until the top is lightly browned and everything is heated all the way through. Serve hot or warm.
