Fettuccine with Shrimp and Spinach

There’s something irresistibly comforting about a bowl of pasta tossed with succulent shrimp, bright lemon, and tender spinach. This Fettuccine with Shrimp and Spinach recipe is quick enough for weeknights yet elegant enough for a weekend dinner. It uses a single box of 16 oz dry fettuccine and simple pantry staples—butter, garlic, Old Bay seasoning, Parmesan, and a splash of lemon—so you can turn out a flavorful plate without fuss. The sauce is light and glossy, clinging to each ribbon of pasta and coating the shrimp for a balanced bite every time.

Why this Fettuccine with Shrimp and Spinach works

Texture and contrast are the keys here. The fettuccine provides a broad, satisfying bite. Shrimp cook quickly and bring a tender, slightly sweet flavor that pairs beautifully with the tang of lemon and the savory depth of Parmesan. Spinach wilts into the sauce, adding color and a mild earthy note without overwhelming the other flavors. Using a measured amount of butter keeps the sauce silky without being heavy, and Old Bay Seasoning adds a warm, well-rounded seasoning that complements seafood perfectly.

Ingredient notes

• 16 oz dry fettuccine pasta (1 box) — Cook according to package directions until al dente so it holds up when tossed with the sauce.
• 3 tbsp butter — Provides the base for sautéing and creates a glossy sauce.
• 1 lb shrimp, peeled and deveined — Use fresh or fully thawed frozen shrimp for best texture. Size can vary; adjust cooking time slightly if using very large shrimp.
• 2 tsp Old Bay Seasoning — A signature blend that enhances the shrimp with a well-balanced savory flavor.
• 1 large garlic clove, finely chopped — Fresh garlic gives bright aromatic notes; chop finely so it distributes through the sauce.
• 8 oz baby spinach — Adds color, nutrients, and a tender leafy texture once wilted.
• 1 ½ tbsp lemon juice — Freshly squeezed is best; it brightens and balances the richness of butter and Parmesan.
• 1 cup shredded Parmesan cheese — Use a good-quality Parmesan for maximum flavor. It melts into the sauce and creates a lightly creamy coating.
• ¼ cup chopped parsley — Fresh parsley adds a herbaceous finish and a pop of color.
• Lemon slices and Parmesan to garnish — Optional, but pretty and practical for extra brightness and cheese at the table.

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan
• Tongs or pasta fork
• Colander
• Measuring spoons and cups

Make-ahead and serving suggestions

This pasta is best served immediately, while the shrimp remain tender and the sauce is glossy. If you need to make parts ahead, cook the pasta until just shy of al dente and toss with a tiny drizzle of olive oil to prevent sticking; reheat briefly with the sauce before serving. Leftovers keep well for one day in an airtight container. Rewarm gently over low heat with a splash of water or extra lemon juice to revive the sauce.

Step-by-step instructions

The following directions are rewritten for clarity and follow the original order of steps, while matching the ingredient list exactly.

1. Bring a large pot of salted water to a rolling boil. Add the 16 oz dry fettuccine pasta and cook according to the package directions until al dente. Reserve about 1 cup of the pasta cooking water, then drain the pasta in a colander and set it aside.
2. While the pasta cooks, heat a large skillet over medium heat. Add 3 tbsp butter to the skillet and let it melt, swirling so it coats the bottom evenly.
3. Once the butter is melted and starting to foam, add 1 lb shrimp that have been peeled and deveined. Sprinkle the shrimp with 2 tsp Old Bay Seasoning. Cook the shrimp for about 1–2 minutes per side, depending on their size, until they turn opaque and curl slightly. Remove the cooked shrimp from the skillet and set them aside on a plate to keep warm.
4. Reduce the heat to low-to-medium and add the finely chopped clove of garlic to the same skillet. Sauté the garlic briefly for 30–45 seconds, stirring constantly, until it becomes fragrant but not browned.
5. Add 8 oz baby spinach to the skillet with the garlic. Toss or stir the spinach until it wilts down, which should take about 1–2 minutes. If the pan looks dry, add a splash of the reserved pasta water to help the spinach cook and loosen any browned bits from the pan.
6. Return the cooked shrimp to the skillet with the wilted spinach. Pour in 1 ½ tbsp lemon juice, stirring to combine. Let everything heat together for about 30 seconds so the flavors marry.
7. Add the drained fettuccine to the skillet. Toss the pasta with the shrimp and spinach, adding small amounts of the reserved pasta cooking water as needed to create a silky coating. You may not need the full cup; add just enough so the sauce clings to the noodles without becoming watery.
8. Sprinkle 1 cup shredded Parmesan cheese over the pasta and toss until the cheese melts and forms a light, cohesive sauce. If the mixture seems too thick, add another tablespoon or two of the reserved pasta water to loosen it.
9. Stir in ¼ cup chopped parsley for freshness and toss one more time to distribute everything evenly.
10. Transfer the pasta to serving bowls or a large platter. Garnish with lemon slices and additional Parmesan cheese as desired. Serve immediately while hot.

Troubleshooting tips

• If the sauce separates or seems greasy, add a splash of the reserved pasta water and toss vigorously to emulsify the butter and cheese into a smooth coating.
• If the shrimp are overcooked and rubbery, for future batches reduce the cooking time and watch for the moment they turn opaque; shrimp cook quickly and carryover heat will keep them warm when tossed with the pasta.
• If the pasta feels bland, a final squeeze of lemon or a pinch more Old Bay Seasoning can lift the flavors instantly.

Flavor variations

There are a few easy swaps you can make while keeping the spirit of this Fettuccine with Shrimp and Spinach intact:

• Swap the baby spinach for a mix of baby kale and spinach for a heartier green.
• Add a pinch of red pepper flakes when sautéing the garlic for a touch of heat.
• Fold in a tablespoon of cream at the end for an extra-lush sauce, if you prefer a creamier texture.
