This lemon-garlic shrimp and orzo skillet is a one-pan evening dinner with tender shrimp, cherry tomatoes, spinach, and Parmesan folded through a bright, savory pasta. It comes together on the stovetop in about 45 minutes, and the orzo cooks directly in broth so it absorbs flavor as it softens.
Ingredients
- 1 pound (450 g) large raw shrimp, peeled and deveined, thawed if frozen
- 1½ cups (300 g) dry orzo
- 2 tablespoons (30 ml) olive oil
- 1 medium yellow onion, finely chopped, about 1 cup (150 g)
- 3 garlic cloves, minced, about 1 tablespoon (9 g)
- 1 pint (300 g) cherry tomatoes, halved
- 3 cups (710 ml) low-sodium chicken broth, or vegetable broth
- ½ teaspoon (1 g) dried oregano
- ¼ teaspoon (0.5 g) red pepper flakes, or less to taste
- ½ teaspoon (3 g) fine salt, plus more to taste
- ¼ teaspoon (0.5 g) ground black pepper
- 1 medium lemon, about 4 ounces (115 g), finely grated zest and 2 tablespoons (30 ml) juice
- 2 cups (60 g) baby spinach
- ⅓ cup (30 g) finely grated Parmesan
- 1 tablespoon (14 g) unsalted butter
- 2 tablespoons (8 g) chopped fresh parsley
Instructions
- Prepare the ingredients. If the shrimp are frozen, thaw them in the refrigerator or in a sealed bag submerged in cold water, changing the water as needed. Pat thawed shrimp dry with paper towels; excess moisture can dilute the seasoning and make the skillet watery. Chop the onion, mince the garlic, halve the tomatoes, zest and juice the lemon, and measure the remaining ingredients before you start cooking. Keeping the shrimp chilled while you prepare the vegetables helps maintain safe handling.
- Soften the onion and tomatoes. Heat the olive oil in a large, deep skillet or sauté pan over medium heat. Add the onion and cook for about 4 minutes, stirring occasionally, until softened but not browned. Stir in the garlic, oregano, red pepper flakes, salt, and black pepper, and cook for 30 seconds, just until fragrant. Add the halved tomatoes and cook for about 1½ minutes, stirring once or twice. The tomatoes should begin to release a little juice but do not need to collapse.
- Toast the orzo. Add the dry orzo and stir for 2 minutes so the pieces are lightly coated in oil and aromatics. Toasting adds a gently nutty flavor and helps the pasta cook evenly. Pour in the broth and scrape the bottom of the pan with a wooden spoon to loosen any browned bits. Bring the liquid to a gentle boil, then lower the heat so it simmers steadily.
- Simmer until nearly tender. Cook uncovered for 10 minutes, stirring every 2 to 3 minutes so the orzo does not settle and stick to the pan. Keep the heat moderate; a hard boil can reduce the broth too quickly before the pasta is tender. After 10 minutes, taste a piece of orzo. It should be close to al dente, with a little firmness at the center, and some liquid should remain around it. If the pan looks dry while the pasta is still firm, stir in a splash of hot broth or water.
- Add and cook the shrimp. Nestle the shrimp in a single layer over the orzo, then cover the skillet and cook for 3 to 4 minutes, turning the shrimp once if they are especially large. Check the thickest shrimp with a food thermometer: the USDA FSIS safe minimum internal temperature for seafood is 145°F (63°C). The flesh should also be opaque and firm. If the shrimp have not reached that temperature, cover and cook for another 30 seconds before checking again; avoid relying on color alone.
- Finish the skillet. Turn off the heat. Stir in the spinach, lemon zest, lemon juice, Parmesan, butter, and parsley until the spinach wilts and the butter melts, about 1 minute. The residual heat will finish softening the spinach without overcooking it. Taste the orzo and adjust the salt, pepper, or lemon juice. Serve promptly, while the sauce is creamy and the shrimp are tender.
Tips
- Choose shrimp that are similar in size. Large shrimp cook more evenly than a mix of small and jumbo pieces. If using smaller shrimp, start checking them after 2 minutes; they may reach 145°F (63°C) sooner. If the shrimp have shells, peel and devein them before cooking for an easier-to-eat skillet.
- Stir the orzo regularly. Unlike rice cooked in a covered pot, orzo can stick to the bottom of a shallow pan as its starch thickens the broth. Scrape the base gently every few minutes, especially around the edges, and keep the simmer gentle rather than vigorous.
- Adjust the broth as needed. Different pans and stovetops evaporate liquid at different rates. Keep a little extra broth or water nearby and add it a few tablespoons at a time if the orzo is still firm but the pan is nearly dry. If the pasta is done and the mixture looks loose, let it stand off the heat for 2 minutes; it will thicken as it rests.
- Use fresh lemon at the end. Lemon juice can taste muted if it cooks for a long time, so adding it after turning off the heat keeps the finished dish bright. For a milder flavor, begin with 1 tablespoon (15 ml) juice, taste, and add more only if you want extra tang.
Serving Suggestions
This skillet is a complete dinner with pasta, seafood, tomatoes, and greens, so it does not need a complicated side. Serve it in warm shallow bowls and spoon the tomatoey broth over each portion. A simple green salad dressed with olive oil and vinegar adds crispness, while steamed green beans or roasted zucchini are easy vegetable sides if you want a larger meal.
Crusty bread is useful for scooping up any broth and melted Parmesan left in the bowl. Put extra lemon wedges and grated Parmesan on the table so everyone can season their portion. If serving the skillet family-style, bring the pan to the table only if its handle is protected and the pan is stable; otherwise, transfer the food to a warmed serving dish. The orzo thickens as it sits, so serve soon after finishing and loosen any portions that have rested with a spoonful of warm broth.
Variations
Make it dairy-free: Leave out the butter and Parmesan, then finish with an extra tablespoon of olive oil and a little more lemon zest. The result will be less creamy and savory, but the tomatoes, garlic, and broth still give the orzo plenty of flavor. For a dairy-free cheesy note, use a plant-based Parmesan-style topping that you already enjoy.
Use another protein: Scallops can replace the shrimp, but their cooking time depends on size; check them with a thermometer and cook seafood to 145°F (63°C). For chicken, use small pieces of boneless chicken breast or thigh and cook them in the skillet before adding the orzo, checking that poultry reaches 165°F (74°C) with a food thermometer. Do not add raw chicken at the same stage as the shrimp, because the orzo’s short finishing time is not enough to cook it safely.
Change the vegetables: Replace the spinach with 2 cups (60 g) chopped kale, adding it with the broth so it has time to soften. Diced zucchini can go in with the tomatoes, while frozen peas can be stirred in during the final 2 minutes. If tomatoes are out of season, use 1 cup (240 g) drained canned diced tomatoes; the sauce will be slightly softer and more concentrated.
Make it mild or spicier: Omit the red pepper flakes for a gentle family-style dinner, or increase them to ½ teaspoon (1 g) for noticeable heat. A pinch of smoked paprika gives a warm, smoky note, though it changes the clean lemon-and-herb flavor of the original. Add seasonings gradually, since broth and Parmesan can both contribute salt.
Storage and Reheating
Refrigerate leftovers within 2 hours of cooking, dividing them into shallow, airtight containers so they cool promptly. Keep them refrigerated for 3 to 4 days. The orzo will absorb more liquid as it rests, and shrimp can become firmer after chilling, so leftovers are best reheated gently rather than boiled again. Do not leave the skillet at room temperature for more than 2 hours, or more than 1 hour when the surrounding temperature is above 90°F (32°C).
For the stovetop, put a portion in a small saucepan with 1 to 2 tablespoons (15 to 30 ml) of water or broth per serving. Cover and warm over low to medium-low heat, stirring occasionally, until steaming throughout. In a microwave, cover loosely and heat in short intervals, stirring between intervals and adding a little liquid if needed. Reheat leftovers to 165°F (74°C), checked with a food thermometer. Reheat only the portion you plan to eat, since repeated warming can make shrimp tough and pasta mushy.
Freezing is possible, although the shrimp may become firmer and the orzo softer after thawing. For best quality, freeze portions in airtight freezer-safe containers for up to 2 months. Thaw in the refrigerator, then reheat as described above to 165°F (74°C). Do not thaw the meal on the counter, and discard leftovers that have been left out beyond the safe time limit.
Frequently Asked Questions
Can I use frozen shrimp?
Yes. Thaw the shrimp before adding them so they cook evenly and do not release a large amount of ice into the skillet. The refrigerator is the easiest method if you plan ahead; for a faster option, keep the shrimp in a sealed bag and submerge it in cold water. Pat the shrimp dry after thawing, and keep them refrigerated until they go into the pan.
Can I use a different pasta instead of orzo?
Orzo is a small, rice-shaped pasta that cooks quickly in the broth. Small pasta shapes such as ditalini or small shells can work, but they may need a different amount of liquid and a longer cooking time, so follow the package timing and check often. Long pasta is not a direct substitute because it is harder to cook evenly in this shallow skillet. If using another shape, add broth as needed and cook the shrimp only once the pasta is nearly tender.
Why is my orzo still firm or sticking?
Orzo can stay firm if the simmer is too low or the liquid evaporates before the pasta has absorbed enough. Add warm broth or water a few tablespoons at a time and continue simmering until tender. If it sticks, the heat may be too high or the pan may not have been stirred often enough. Scrape the bottom gently every few minutes, and avoid leaving the pan at a rolling boil.
Can I make this recipe without chicken broth?
Yes. Vegetable broth works well, and water can be used in a pinch. Broth provides a fuller savory base, while water makes the finished orzo milder, so taste and adjust the salt and Parmesan at the end. If your broth is salted, begin with less added salt than the ingredient list suggests, then season the finished dish to taste.
How can I tell when the shrimp are done?
Use a food thermometer to check the thickest shrimp; seafood should reach the USDA FSIS safe minimum internal temperature of 145°F (63°C). Properly cooked shrimp are opaque and firm, but size and pan conditions affect how quickly they cook, so the thermometer is the reliable check. If a reading is below 145°F (63°C), continue cooking briefly and check again rather than leaving them covered for several extra minutes.
Can I prepare any part of the recipe ahead?
You can chop the onion, mince the garlic, halve the tomatoes, and grate the Parmesan earlier in the day; store the prepared ingredients covered in the refrigerator. Thaw and dry the shrimp close to cooking time, and keep them separate from ready-to-eat ingredients. The orzo is best cooked just before serving because it continues absorbing liquid as it sits, though leftovers can be loosened with broth when reheated.
