Introduction
Rich, garlicky, and genuinely hands-off, this crockpot garlic parmesan shrimp pasta recipe turns a classic Italian-inspired flavor combination into a true one-pot slow cooker meal. Pasta simmers right in the crockpot in a savory broth, and a creamy garlic parmesan sauce comes together as the pasta cooks, with tender shrimp stirred in near the end to finish everything off.
I love this one because it takes the effort out of a dish that usually requires babysitting a stovetop sauce and a separate pot of boiling pasta. Everything happens in one crockpot, and by the time the shrimp goes in, you’ve already got a rich, cheesy pasta base ready to bring it all together into a genuinely satisfying dinner.
Serve it straight from the crockpot with a sprinkle of extra parmesan and fresh parsley. However you serve it, this crockpot garlic parmesan shrimp pasta recipe proves that a slow cooker can absolutely handle pasta night.

Ingredient Notes
Small pasta shapes like penne, rotini, or shells work best here since they cook evenly in the crockpot and hold onto the sauce well. Larger or longer pasta shapes tend to cook unevenly in a slow cooker, so it’s worth sticking with something compact and sturdy.
Freshly grated parmesan cheese melts more smoothly into the sauce than the pre-shredded, bagged kind, which often contains anti-caking agents that can leave the sauce slightly grainy. A generous amount of fresh garlic is essential here, since it’s the dish’s signature flavor alongside the parmesan.
For the shrimp, medium to large peeled and deveined shrimp work best, and just like other crockpot shrimp dishes, timing matters most here. Stir it in only during the final 15–20 minutes of cooking, since shrimp cooks quickly and will turn tough and rubbery if left in the slow cooker’s steady heat for the full cook time.
🧄 Crockpot Garlic Parmesan Shrimp Pasta Recipe
Prep Time: 15 minutes | Cook Time: 2–2.5 hours (low) | Total Time: about 2 hours 45 minutes Servings: 6
Ingredients
For the Pasta Base:
- 2 cups penne or rotini pasta, uncooked
- 3 cups chicken broth
- 1 cup heavy cream
- 4 tbsp unsalted butter, cubed
- 6 cloves garlic, minced
- 1 tsp dried Italian seasoning
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper
- Pinch of red pepper flakes (optional)
For the Cheese:
- 1 cup freshly grated parmesan cheese, plus extra for serving
- 4 oz cream cheese, cubed and softened
For the Shrimp:
- 1.5 lbs medium to large shrimp, peeled and deveined
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp smoked paprika
For Finishing:
- 2 tbsp chopped fresh parsley
Instructions
Step 1: Add the pasta and liquid to the crockpot. Add the uncooked pasta, chicken broth, heavy cream, cubed butter, minced garlic, Italian seasoning, salt, pepper, and red pepper flakes (if using) directly to the crockpot. Stir well, making sure the pasta is mostly submerged in the liquid.
Step 2: Cook on low. Cover and cook on low for 2 to 2.5 hours, stirring every 30–45 minutes, until the pasta is tender and most of the liquid has been absorbed. Tip: stirring periodically here is important — it prevents the pasta from sticking together or settling unevenly at the bottom of the crockpot.
Step 3: Season and sear the shrimp. While the pasta cooks, toss the shrimp with salt, pepper, and smoked paprika. About 20 minutes before the pasta finishes, heat a skillet over medium-high heat and sear the shrimp for about 1–2 minutes per side, until just pink and opaque.
Step 4: Stir in the cheese. Once the pasta is tender, stir in the grated parmesan and cream cheese, mixing well until fully melted and smooth. Tip: add the cheese gradually and stir thoroughly between additions — dumping it all in at once can cause it to clump instead of melting evenly.
Step 5: Adjust the consistency. If the pasta seems too thick after the cheese is stirred in, add a splash of extra chicken broth or cream to loosen it to your preferred consistency. Keep in mind it will continue to thicken slightly as it sits.
Step 6: Add the shrimp. Gently fold the seared shrimp into the pasta, being careful not to break up the noodles too much. Cover and cook on low for another 10–15 minutes, just until everything is heated through and the shrimp is fully incorporated.
Step 7: Taste and adjust. Give the dish a final taste and adjust the salt, pepper, or garlic as needed to get the balance right. If you’d like a little extra richness, stir in an additional tablespoon or two of butter at this point.
Step 8: Garnish and serve. Sprinkle with chopped fresh parsley and extra parmesan, then serve warm straight from the crockpot.
Recipe Notes
- Check the pasta a bit earlier than the suggested time if your crockpot tends to run hot, since overcooked pasta can turn mushy.
- Freshly grated parmesan melts far more smoothly than the pre-shredded, bagged kind, so it’s worth grating your own for the best texture.
- This dish also works well with a handful of fresh spinach stirred in along with the shrimp for added color and nutrition.

Storage & Reheating
Leftovers will keep in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop over low heat or in the microwave in short bursts, stirring in a splash of milk or cream to loosen the sauce, which tends to thicken significantly once chilled.
This dish isn’t a great candidate for freezing, since both the pasta and the cream sauce change texture noticeably after thawing. If you’d like to prep ahead, you can measure out the dry ingredients and chop the shrimp a day in advance to make assembly quicker.
Budget Note
This recipe costs about $4–5 per serving, with shrimp and parmesan being the main cost drivers, though it’s still generally more affordable than ordering a similar dish at a restaurant. To stretch it further, use a bit less shrimp and add extra pasta or vegetables to bulk up the dish without significantly increasing the cost.
Variations
Healthier/Lighter Version: Use half-and-half in place of heavy cream and reduce the butter slightly to lighten up the sauce while still keeping it creamy. The texture stays fairly similar, so this swap doesn’t drastically change the eating experience.
Spinach Version: Stir in 2 cups of fresh baby spinach along with the shrimp, letting it wilt into the pasta during the final cooking stage. This adds color, nutrition, and a nice freshness that balances the richness of the sauce.
Spicy Version: Increase the red pepper flakes, or stir in a diced jalapeño along with the garlic for extra heat. A dash of hot sauce mixed into the sauce also works well if you want a spicier kick throughout.
Meal-Prep Friendly: Make a full batch and portion it into containers for easy lunches throughout the week. Reheat gently on the stove or in short microwave bursts, stirring in a splash of milk to keep the sauce smooth and the shrimp from turning tough.
Frequently Asked Questions
Can I make this ahead of time? You can chop the shrimp and measure out the dry ingredients a day in advance, but it’s best to actually cook the pasta and sauce fresh for the best texture. Cooked leftovers do reheat reasonably well, so making a full batch ahead and reheating portions throughout the week also works.
Why is my pasta mushy? This usually happens from cooking it too long or on too high a heat setting. Stick to low heat, check the pasta a bit early if your crockpot tends to run hot, and remove it from heat as soon as it’s tender rather than letting it continue cooking.
Can I use a different pasta shape? Yes — rotini, shells, or any small, compact pasta shape will work well in place of penne. Avoid long noodles like spaghetti or fettuccine, since they don’t cook as evenly in a slow cooker.
Can I use frozen shrimp? Yes — just make sure it’s fully thawed and patted dry before searing, since excess moisture can prevent a good sear and may thin out the sauce slightly. Thaw it overnight in the fridge or under cold running water if you’re short on time.
What should I serve with crockpot garlic parmesan shrimp pasta? A simple green salad or steamed vegetables like broccoli or asparagus pair nicely to balance out the richness of the dish. Garlic bread is also a natural addition if you want to round out the meal even further.
