Instant Pot Shrimp Scampi Pasta
A quick and flavorful one-pot shrimp scampi pasta made in the Instant Pot, featuring garlic, butter, and lemon, perfect for busy weeknights or entertaining.
I still remember the first weeknight I tested this Instant Pot shrimp scampi pasta — ten minutes to sauté, ten minutes to build flavor, and the rest to sit back while the pressure cooker did the heavy lifting. It’s the kind of dinner that feels restaurant-worthy but comes together fast, which is why I reach for it on busy evenings and when entertaining friends who expect big flavor with minimal fuss. If you like bold garlic-butter sauce and tender shrimp with perfectly cooked pasta, this one delivers every time. For another one-pot comfort option that’s great for weeknights, I often pair menus with a hearty pasta like chicken pot pie pasta to mix up family favorites.
Why you’ll love this dish
This Instant Pot shrimp scampi pasta hits a sweet spot: restaurant-style sauce, weeknight speed, and minimal cleanup. Cooking pasta and shrimp together in the pressure cooker concentrates flavors because the garlic, lemon, and butter steam into the pasta while the shrimp cooks quickly on top. It’s budget-friendly when you use frozen shrimp and pantry staples, and it’s flexible — easily doubled for company or pared down for two.
Besides weeknight dinners, it’s a great option for date nights at home, quick entertaining, or when you want something impressive without babysitting a stove.
The cooking process explained
Before we list ingredients, here’s a quick overview so you know what to expect:
- Sauté aromatics (garlic, shallot) in the Instant Pot to bloom flavor.
- Deglaze with chicken broth (or broth) and build the lemon-butter sauce.
- Add uncooked pasta and liquid; lay shrimp on top.
- Pressure-cook briefly so pasta finishes al dente and shrimp cooks just through.
- Quick release, stir in butter and parsley, and serve.
This method keeps the shrimp from overcooking because it’s placed on top of the pasta and finishes during the resting/stirring stage.
What you’ll need
- 1 lb (450 g) shrimp, peeled and deveined (use medium to large; bigger shrimp are easier to avoid overcooking). Frozen shrimp work fine if thawed.
- 8–10 oz (225–285 g) pasta (linguine, spaghetti, or bucatini). Short cuts like penne can work but may change texture.
- 4 tbsp unsalted butter
- 2 tbsp olive oil
- 4–5 cloves garlic, minced
- 1 small shallot, finely chopped (optional; adds sweetness)
- 1/2 cup dry chicken broth or low-sodium chicken broth (substitute: extra broth)
- 2 1/2 cups low-sodium chicken broth or water (liquid for pasta)
- Zest and juice of 1 lemon (about 2 tbsp juice)
- 1/4 tsp red pepper flakes (optional)
- 1/4 cup chopped fresh parsley
- Salt and black pepper to taste
- Grated Parmesan, for serving (optional)
Notes/substitutions: For a dairy-free version, swap butter for extra olive oil. For gluten-free, use GF pasta and adjust cooking time per package.
Directions to follow
- Set the Instant Pot to Sauté and add olive oil and 2 tablespoons of butter. Once hot, add shallot and cook 1–2 minutes until translucent.
- Add garlic and red pepper flakes; sauté 30–45 seconds until fragrant. Don’t let garlic brown.
- Pour in the chicken broth (or broth) and use a wooden spoon to scrape any browned bits from the bottom. Simmer 1 minute to reduce slightly.
- Add the pasta in an even layer and pour the 2 1/2 cups broth over it. Press the pasta down so it’s mostly submerged but don’t stir excessively.
- Nestle the shrimp on top of the pasta in a single layer. Sprinkle with a little salt and pepper. Close the lid, set valve to sealing, and pressure-cook on High for 4 minutes. (If using very thin pasta like angel hair, reduce to 1–2 minutes.)
- Perform a quick release carefully once the cook time ends. Open lid and stir gently — pasta will finish cooking in the hot sauce. If sauce seems thin, set to Sauté and simmer 1–2 minutes to reduce.
- Stir in remaining butter, lemon zest, lemon juice, and parsley. Taste and adjust seasoning. Serve immediately with grated Parmesan if desired.
Short, active steps and a quick-release keep shrimp tender and pasta at the right texture.

Best ways to enjoy it
Serve this scampi pasta straight from the pot into warm bowls for a cozy presentation. Pairing ideas:
- A crisp green salad with lemon vinaigrette to echo the dish’s brightness.
- Garlic bread or crusty baguette to mop up the sauce.
- Sparkling lemonade or a chilled citrus soda complement the lemon and garlic. For a non-alcoholic option, sparkling water with a lemon wedge works well.
For a family-style dinner, place lemon wedges and extra parsley on the table. If you want a Tex-Mex twist for a casual night, try the tangy side dishes you’d serve with taco pasta to mix up the plate.
How to store & freeze
Refrigerator: Cool leftovers within two hours and store in an airtight container for up to 3 days. Shrimp-based dishes don’t keep as long as purely vegetable or grain dishes.
Reheating: Reheat gently on the stovetop over low heat with a splash of water or broth to loosen the sauce, or microwave in short bursts, stirring between intervals. Avoid high heat which makes shrimp rubbery.
Freezing: Not recommended for best texture — shrimp and pasta both can become mushy after freezing. If you must freeze, place in a shallow airtight container for up to 1 month. Thaw overnight in the fridge and reheat gently.
Food safety: Always cool and refrigerate within 2 hours of cooking and reheat to at least 165°F (74°C) before serving.
Creative twists
- Spicy tomato scampi: Add 1/2 cup crushed tomatoes before pressure cooking.
- Lemon-herb skillet: Finish with 1 tbsp capers and extra parsley for tang.
- Gluten-free: Use GF pasta and follow package timing; you may need a minute less in the Instant Pot.
- Vegetarian swap: Replace shrimp with sautéed mushrooms and roasted cauliflower, and use vegetable broth.
- Creamy parmesan: Stir in grated Parmesan and a splash of cream after pressure cooking for a richer finish.
Helpful answers
Can I use frozen shrimp straight from the freezer?
A: I don’t recommend it for this method because frozen shrimp releases water and can affect timing and texture. Thaw under cold water first.
What if my Instant Pot gives a burn notice?
A: Cancel Sauté, open and deglaze thoroughly with the chicken broth/broth, scraping the bottom. Make sure there are no stuck bits before adding pasta and liquid.
Can I double the recipe?
A: Yes, but don’t overfill your Instant Pot. Keep at or below the max fill line and increase liquid proportionally. You may need to stagger batches for best results.
How do I know when shrimp are done?
A: Shrimp turn opaque and curve into a loose “C”. If they curl tightly into an “O”, they’re overcooked.
Can I make this dairy-free?
A: Yes — use olive oil instead of butter and omit Parmesan.
