Introduction
Bright, buttery, and just a little indulgent, this crockpot creamy lemon butter shrimp recipe is the kind of dinner that feels fancy without asking much of you. A silky lemon-butter sauce simmers away in the slow cooker while you handle the rest of your day, and the shrimp gets stirred in right at the very end so it stays tender and never rubbery.
There’s something so satisfying about a sauce that’s rich from butter and cream but lifted by fresh lemon — it keeps every bite from feeling heavy, even though it tastes plenty decadent. This is the dinner I make when I want something that feels a little special but still fits into a normal weeknight.
Spoon it over pasta, rice, or mashed potatoes, or just serve it with warm crusty bread for scooping up every last drop of sauce. However you plate it, this one’s going to earn a permanent spot in your dinner rotation.

Ingredient Notes
Fresh lemon juice and zest are what set this dish apart, so skip the bottled lemon juice if you can — fresh really does make a noticeable difference in brightness and aroma. If you’re zesting, do it before you juice the lemon; it’s much easier to zest a whole lemon than a juiced, floppy half.
Butter and heavy cream form the base of the sauce, giving it that rich, glossy texture worth writing home about. Half-and-half can be used in place of heavy cream for a slightly lighter sauce, though it won’t thicken quite as much on its own, so you may want to let it reduce a bit longer or add a small cornstarch slurry near the end.
For the shrimp, medium to large peeled and deveined shrimp work best, and as with any crockpot shrimp dish, timing is everything. Stir it in only during the final 15–20 minutes of cooking — shrimp cooks fast, and letting it sit in the slow cooker’s steady heat for the full cook time will leave it chewy instead of tender.
🍋 Crockpot Creamy Lemon Butter Shrimp Recipe
Prep Time: 15 minutes | Cook Time: 2–2.5 hours (low) | Total Time: about 2 hours 45 minutes Servings: 4–6
Ingredients
For the Lemon Butter Sauce:
- 6 tbsp unsalted butter, cubed
- 4 cloves garlic, minced
- 1 small shallot, finely diced (or 1/4 cup diced yellow onion)
- 1 cup chicken broth
- 1 cup heavy cream
- Zest of 1 lemon
- 1/4 cup fresh lemon juice (about 2 lemons)
- 1/2 tsp dried Italian seasoning
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper
- Pinch of red pepper flakes (optional, for a little heat)
- 1/3 cup grated parmesan cheese
For the Shrimp:
- 1.5 lbs medium to large shrimp, peeled and deveined
- 1 tbsp fresh lemon juice
- 1/4 tsp salt
- Pinch of black pepper
For Serving/Garnish:
- Cooked pasta, rice, or mashed potatoes
- 2 tbsp chopped fresh parsley
- Extra lemon wedges and grated parmesan, for serving
Instructions
Step 1: Start the sauce base. Add the cubed butter, minced garlic, and diced shallot directly to the crockpot. There’s no need to pre-cook anything on the stove — the slow cooker will gently melt the butter and soften the garlic and shallot as it heats up.
Step 2: Add the liquids and seasoning. Pour in the chicken broth and heavy cream, then stir in the lemon zest, lemon juice, Italian seasoning, salt, pepper, and red pepper flakes (if using). Stir everything together so the seasoning is evenly distributed through the liquid. Tip: add the lemon juice now rather than at the very end — cooking it in gently mellows any sharp edge while still keeping the sauce bright.
Step 3: Cook on low. Cover and cook on low for 2 to 2.5 hours, until the shallot is soft and the sauce has come together into a fragrant, slightly thickened base. Avoid cooking on high, since a gentler heat keeps the dairy from separating or curdling over the cook time.
Step 4: Stir in the parmesan. About 15 minutes before adding the shrimp, stir the grated parmesan into the sauce until melted and smooth. This adds a subtle savory depth and helps thicken the sauce slightly, rounding out the bright lemon flavor with something richer.
Step 5: Season the shrimp. While the sauce finishes coming together, toss the raw shrimp in a bowl with the extra tablespoon of lemon juice, salt, and pepper. This quick step layers a little extra brightness directly onto the shrimp itself, rather than relying on the sauce alone to carry all the flavor.
Step 6: Add the shrimp and finish cooking. Stir the seasoned shrimp into the sauce, cover, and cook on low for another 15–20 minutes, just until the shrimp are pink, opaque, and cooked through. Tip: check at the 15-minute mark — shrimp can go from tender to rubbery quickly, so it’s better to pull it a touch early than to leave it too long.
Step 7: Taste and adjust. Give the sauce a final taste, adjusting salt, pepper, or lemon juice as needed to get the balance right. If you’d like the sauce thicker, mix 1 teaspoon of cornstarch with 1 tablespoon of cold water and stir it in during the last few minutes of cooking.
Step 8: Serve. Spoon the creamy lemon butter shrimp over pasta, rice, or mashed potatoes, or serve it straight from the crockpot with warm crusty bread for dipping. Finish with a sprinkle of fresh parsley, extra parmesan, and a lemon wedge on the side for anyone who wants an extra pop of brightness.
Recipe Notes
- If you prefer an extra glossy, restaurant-style finish, stir in an additional 1–2 tablespoons of cold butter right before serving.
- Frozen shrimp works well here as long as it’s fully thawed and patted dry first, since excess moisture will thin out the sauce.
- Leftover sauce (without shrimp) makes a wonderful base for a quick lemon butter chicken or vegetable dish later in the week.

These numbers are estimates based on standard ingredients and do not include pasta, rice, or bread served alongside. Actual values will vary depending on brands and exact portions used.
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, stirring often, and add a splash of extra broth or cream if the sauce has thickened too much in the fridge — this helps bring it back to its original silky texture without overcooking the shrimp.
This dish doesn’t freeze particularly well, since cream-based sauces tend to separate once thawed. If you want to plan ahead, freeze just the lemon butter sauce base before the shrimp and parmesan are added, then finish those final steps fresh after thawing.
Budget Note
This recipe costs around $4–5 per serving, with shrimp being the biggest expense. To make it more budget-friendly, look for frozen shrimp on sale and buy in bulk bags rather than from the fresh seafood counter, and stretch the dish further by serving it generously over pasta or rice rather than adding more shrimp.
Variations
Healthier/Lighter Version: Use half-and-half in place of heavy cream and reduce the butter slightly to cut down on richness while still keeping that classic lemon butter flavor. The sauce will be a touch thinner, but the bright lemon notes still shine through.
Keto/Low-Carb Version: This recipe is naturally low-carb as written, especially when served over zucchini noodles or a simple side of sautéed greens instead of pasta or rice. Just double-check that your chicken broth and parmesan don’t contain any added sugars or fillers.
Instant Pot Method: For a quicker version, sauté the butter, garlic, and shallot directly in the Instant Pot using the sauté function, then stir in the broth, cream, lemon juice, and seasonings and let it simmer on sauté for 5 minutes to meld the flavors. Stir in the parmesan, then add the shrimp and cook using the sauté function for another 3–4 minutes until just opaque and cooked through.
Meal-Prep Friendly: Make a full batch and portion it into containers with rice or pasta for easy lunches throughout the week. Reheat gently on the stove or in short microwave bursts, stirring frequently, to keep the shrimp from turning tough.
Frequently Asked Questions
Can I make this ahead of time? Yes — you can prepare the lemon butter sauce a day in advance and store it in the fridge, then reheat it gently in the crockpot or on the stove and stir in fresh shrimp when you’re ready to serve. This keeps the shrimp perfectly tender instead of overcooked from sitting too long.
What can I use instead of heavy cream? Half-and-half works as a lighter substitute, though the sauce won’t be quite as thick or rich. Avoid using plain milk on its own, since it’s more likely to separate under the slow cooker’s steady heat over a longer cook time.
Is this recipe very lemony? It has a noticeable, bright lemon flavor that balances the richness of the butter and cream, but it’s not overwhelmingly tart. You can adjust the amount of lemon juice up or down slightly to match your personal taste.
Can I use a different protein instead of shrimp? Yes — this sauce pairs beautifully with chicken as well, though chicken will need a longer cook time added directly to the crockpot with the sauce rather than stirred in at the end like shrimp. Scallops are another great option and follow a similar quick-add timing to shrimp.
What should I serve with crockpot creamy lemon butter shrimp? Pasta, rice, or mashed potatoes are all wonderful for soaking up the sauce, while a simple green salad or steamed asparagus adds a fresh, light contrast. Crusty bread on the side is never a bad idea either, especially for scooping up extra sauce.
