About This Recipe
Here's what most people don't know about shrimp scampi: authentic Italian families from the Veneto region never actually put pasta in the dish. True 'scampi' refers to langoustines sautéed in garlic, white wine, and butter - that's it. The pasta version we love? That's pure Italian-American genius from the 1920s, when Italian immigrants in New York couldn't find langoustines and substituted shrimp, then started serving it over linguine to make it more filling for working families. Each Italian-American neighborhood developed its own twist - some added red pepper flakes (Sicilian influence), others used more lemon (Amalfi Coast style). The pressure cooker method actually mimics how many Italian-American grandmothers would finish the dish - they'd toss everything in one pot after the initial sauté, cover it, and let the steam marry all those flavors together. That's why the Instant Pot version tastes so authentic - you're accidentally following a century-old Italian-American technique.

How to Make 20 Minute Instant Pot Shrimp Scampi Pasta
- Special equipment: a 6- or 8-quart Instant Pot® multi-cooker
- Add the butter, olive oil, and garlic to a 6- or 8-quart Instant Pot® multi-cooker and set to high saute. Cook, stirring often until the garlic is softened but not browned, about 3 minutes. Add the wine, lemon juice and zest, red pepper flakes, 2 teaspoons salt, and several grinds of pepper. Bring to a boil and let simmer for 2 minutes. Add 2 cups water, then add half of the pasta all in one direction and then the other half of the pasta in a criss-cross fashion. Top with the shrimp.
- Follow the manufacturer's guide for locking the lid and preparing to cook. Set to pressure cook on high for 1 minute. After the pressure-cook cycle is complete, follow the manufacturer's guide for natural release. After 5 minutes, being careful of any remaining steam, unlock and remove the lid.
- Using tongs, toss the pasta to coat with the sauce and break up any clumps. Top with Italian parsley and parmesan cheese. Serve with salad and garlic bread.
- Enjoy, buen provecho!
- Settings may vary on your Instant Pot® depending on the model. Please refer to the manufacturer's guide.

What to Serve With 20 Minute Instant Pot Shrimp Scampi Pasta
A crisp arugula salad with lemon vinaigrette cuts beautifully through the rich, garlicky butter sauce in this scampi. The peppery bite of arugula contrasts perfectly with the sweet shrimp, while the citrus brightens every forkful without competing with those bold Italian flavors.
My garlic herb focaccia bread is absolutely perfect for soaking up every drop of that incredible scampi sauce – trust me, you don't want to waste a single bit. The soft, pillowy texture and aromatic herbs complement the pasta without overwhelming the delicate shrimp, making it the ultimate comfort food pairing.
For something completely different, try serving this alongside tostones – those twice-fried plantains from my Dominican roots. The crispy, starchy sweetness of the plantains creates an unexpected but gorgeous contrast to the buttery pasta, bridging Italian and Caribbean flavors in the most delicious way possible.
Frequently Asked Questions
1. Can I really make shrimp scampi pasta in 20 minutes?
Yes — the Instant Pot pressure cooks the pasta directly in the garlic butter sauce in just 4 minutes. Total time including prep and pressurization is about 20 minutes.
2. Do I cook the shrimp under pressure?
No — add the shrimp after pressure cooking the pasta. Use the residual heat to cook them for 3-4 minutes until pink. Shrimp overcook quickly and would become rubbery under pressure.
3. What pasta works in the Instant Pot?
Linguine broken in half, penne, or angel hair work best. Set the pressure cook time to half the package cooking time. For linguine, 4 minutes on high pressure is standard.
4. How much liquid do I need?
Just enough broth to cover the pasta — about 3 cups for a pound of pasta. The Instant Pot retains all moisture, so you need less liquid than stovetop cooking.
5. What is in the scampi sauce?
Butter, garlic (lots of it), white wine, chicken broth, lemon juice, and red pepper flakes. The pasta absorbs all these flavors as it pressure cooks directly in the sauce.
6. Should I saute the garlic first?
Yes — use the Instant Pot's saute function to cook the garlic in butter for 30 seconds before adding the liquid and pasta. This blooms the garlic flavor into the butter.
7. Why do I need to deglaze after sauteing?
Adding the wine or broth and scraping the bottom removes any garlic or butter residue. Skipping this step can trigger the Instant Pot's burn warning during pressure cooking.
8. What size shrimp should I use?
Large (21-25 count) shrimp, peeled and deveined. Add them to the hot pasta after releasing pressure — they cook in 3-4 minutes from the residual heat without becoming tough.
9. What do I add after pressure cooking?
Shrimp, extra butter, lemon juice, Parmesan, and fresh parsley all go in after the pressure releases. The hot pasta finishes cooking the shrimp and melts the butter and cheese.
10. Can I use frozen shrimp?
Thaw frozen shrimp under cold water first. Adding frozen shrimp to the hot pasta cools it too quickly and the shrimp will not cook through properly from residual heat alone.

Notes
Buy shell-on shrimp and peel them yourself because the shells contain natural gelatin that enriches your cooking liquid - I save those shells and toss them right into the Instant Pot with everything else, then strain them out before serving for deeper flavor. Use day-old bread for your garlic breadcrumbs instead of fresh because slightly stale bread crisps better and won't get soggy when it hits that buttery pasta - I learned this after too many mushy-topped disasters in my early pressure cooking days. Add your white wine to the cold Instant Pot before heating because alcohol needs time to cook off properly under pressure - if you add it to an already hot pot, you'll get that harsh, boozy bite instead of mellow complexity. Finish with cold butter off heat and toss vigorously because the temperature contrast creates an emulsion that coats each strand of pasta perfectly - this Italian technique called 'mantecatura' is what makes restaurant scampi so silky compared to home versions.
