01 - Heat 1 tbsp olive oil in a large, deep skillet over medium-high heat. Pat the shrimp dry with paper towels and season lightly with salt, pepper, and smoked paprika. Sear for 2–3 minutes per side until just pink and opaque. Transfer to a plate and set aside.
02 - Add the remaining 1 tbsp olive oil to the same skillet. Sauté the onion for 2–3 minutes until translucent. Stir in the garlic and chili flakes if using, and cook until fragrant, about 30 seconds.
03 - Add the orzo to the pan and toast for 1–2 minutes, stirring constantly to coat the pasta evenly in the oil and aromatics.
04 - Pour in the broth, lemon juice, and lemon zest. Stir well, scraping up any browned bits from the bottom of the pan. Bring to a boil, then reduce the heat and simmer uncovered for 7–10 minutes, stirring occasionally, until the orzo is al dente and most of the liquid has been absorbed.
05 - Stir in the cherry tomatoes and baby spinach. Cook for 1–2 minutes until the spinach is wilted and the tomatoes have softened slightly.
06 - Return the seared shrimp to the skillet and gently toss everything together. Cook for 2 more minutes until the shrimp are heated through. Adjust seasoning with salt and pepper as needed.
07 - Remove from heat and sprinkle generously with fresh chopped parsley. Serve immediately with lemon wedges on the side.
