Step 1

Preheat the oven to 450 degrees F. Line a large rimmed baking sheet with parchment paper or a silicone baking mat.

Step 2

Cook the vegetables: Zest the lemon into a large bowl. Add 1 tablespoon lemon juice (reserve the lemon's remaining juice for the shrimp and serving), oil, garlic, salt, pepper, and oregano. Whisk to combine.

Step 3

Add the artichokes, tomatoes, olives, and onion.

Step 4

Trim off the ends of the zucchini, then quarter lengthwise so that you have four batons. Slice the batons crosswise into ½-inch pieces. Add them to the bowl with the other vegetables. With your hands or a large spoon (hands are easier) toss to coat.

Step 5

Transfer the mixture to a large rimmed baking sheet and spread it into an even layer (keep the bowl handy; no need to clean it yet). Place in the oven and bake until the tomatoes begin to soften and release their juices, about 12 minutes.

Step 6

Prep the shrimp: While the vegetables are cooking, in the same bowl you used for the vegetables, stir together 1 tablespoon lemon juice, oil, oregano, red pepper, garlic, and salt. Add the shrimp and toss to coat.

Step 7

Remove the baking sheet from the oven and add the shrimp (discard any liquid that collects in the bowl). With a large spatula, stir to combine the shrimp and vegetables together. Spread back into an even layer.

Step 8

Return to the oven and continue baking until the shrimp are pink, opaque, and cooked through, 6 to 10 minutes more depending upon the size of your shrimp. Do not overcook! As soon as the shrimp look opaque and pink, they are cooked.

Step 9

Remove the pan from the oven. Sprinkle with the feta and parsley and squeeze the remaining 1 to 2 tablespoons lemon juice over the top. Season with a pinch of additional salt and black pepper to taste. Serve warm with rice or baguette slices.
