Creamy Tuscan shrimp has that restaurant-special feel — sun-dried tomatoes, wilted spinach, garlic, and a rich Parmesan cream sauce all coming together in one dreamy dish. This slow cooker version gives you all of that flavor with almost none of the effort, and the best part is that the shrimp go in straight from frozen. No thawing, no planning ahead, no soggy shrimp sitting in a bowl of water on the counter.
The slow cooker does most of the heavy lifting here, letting the garlic, sun-dried tomatoes, and Italian seasoning slowly build a deeply flavorful base before the shrimp go in at just the right moment to cook gently without turning tough. By the time everything’s ready, you’ve got a rich, creamy, slightly tangy sauce clinging to tender shrimp and wilted spinach — the kind of dinner that feels far more impressive than the effort it actually took.
This recipe has been tested specifically with frozen shrimp in mind, since timing matters a lot more with seafood than with chicken or beef in a slow cooker. Add the shrimp too early and they turn rubbery; add them too late and they don’t fully cook. This version walks you through exactly when to add them so you get perfectly tender shrimp every time.

Ingredient Notes
Sun-dried tomatoes are the backbone of the “Tuscan” flavor here, and the oil-packed kind tend to be more flavorful and tender than the dry-packed variety, which can be a little chewy if not rehydrated first. If you only have dry-packed sun-dried tomatoes, soak them in warm water for about 10 minutes before chopping and adding them to the slow cooker.
For the greens, fresh baby spinach is the easiest option since it wilts down quickly once stirred into the warm sauce at the end. Frozen chopped spinach can also work in a pinch, just be sure to thaw and squeeze out as much excess water as possible first, or it can water down the sauce. Kale is a heartier substitute if you prefer, though it may need a few extra minutes to soften.
As for the shrimp, frozen, peeled, and deveined shrimp in the medium-to-large range (31/40 or 26/30 count) hold up best without turning tough during the shorter high-heat cooking window. A good-quality Parmesan, freshly grated if possible, makes a noticeable difference in how smoothly the sauce comes together compared to the pre-shredded, anti-caking-coated kind.

Step-by-Step Instructions
- Build the sauce base in the slow cooker. Add the chicken broth, minced garlic, chopped sun-dried tomatoes, Italian seasoning, and a splash of the sun-dried tomato oil directly to the slow cooker insert and stir to combine. Tip: using a bit of the flavorful oil from the sun-dried tomato jar adds extra depth without any additional effort.
- Cook the base low and slow. Cover and cook on LOW for 2–3 hours, or on HIGH for 1–1.5 hours, to let the garlic and tomatoes infuse the broth. Tip: this step matters more than it seems — a well-developed base is what separates a flat-tasting Tuscan sauce from a rich one.
- Add the frozen shrimp. Add the shrimp straight from frozen, breaking apart any large clumps, and stir gently to coat in the broth mixture.
- Cook until just opaque. Cover and cook on HIGH for 45–60 minutes, checking at the 45-minute mark. The shrimp are done as soon as they turn pink and opaque throughout. Tip: this is the step to watch closely — shrimp overcook quickly, so check early rather than letting the full hour run if they look done sooner.
- Stir in the cream, Parmesan, and spinach. Add the heavy cream and Parmesan, stirring until melted and smooth, then fold in the fresh spinach and let it wilt for about 5 minutes on LOW. Tip: adding the Parmesan gradually while stirring helps it melt smoothly instead of clumping at the bottom.
- Finish and serve. Taste and adjust salt, pepper, and a squeeze of fresh lemon juice if desired, then serve immediately over pasta, rice, or with crusty bread to soak up the sauce.

Storage & Reheating
Leftovers keep well in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop over low heat, stirring often, or in the microwave in short bursts at reduced power, since cream-based sauces can separate if reheated too quickly or at full power.
Freezing is possible but not ideal, as the cream and Parmesan sauce can turn grainy or separate slightly after thawing. If you do want to freeze it, store the sauce and shrimp together in a freezer-safe container for up to one month, thaw overnight in the fridge, and reheat low and slow, stirring in a splash of fresh cream to help bring the sauce back together.
Budget Note
This recipe runs roughly $4–$5 per serving, with shrimp and sun-dried tomatoes being the priciest ingredients. To bring the cost down, buy shrimp in bulk frozen bags rather than smaller portions, and use dry-packed sun-dried tomatoes (which are usually cheaper than oil-packed) rehydrated in warm water before adding them to the pot.
Variations to Try
Lighter version: Swap the heavy cream for half-and-half and use a reduced-fat Parmesan, keeping the final simmer gentle so the lighter dairy doesn’t separate. The sauce will be a touch thinner but still full of that garlicky, sun-dried tomato flavor.
Keto / low-carb: This recipe is naturally low-carb as written — just skip the pasta and serve it over cauliflower rice or steamed zucchini noodles instead, and double-check your Italian seasoning blend for any hidden added sugar.
Chicken swap: If shrimp isn’t your thing, this same sauce works beautifully with diced or sliced chicken breast — just extend the initial slow cook time to fully cook the chicken through before adding the cream and spinach at the end.
Meal-prep friendly: Portion the finished dish into individual containers with a scoop of rice or pasta, and it holds up nicely in the fridge for a few days. Adding a splash of cream or broth when reheating helps loosen the sauce back to its original consistency.
Frequently Asked Questions
Can I use fresh shrimp instead of frozen? Yes — if using fresh or thawed shrimp, reduce the high-heat cooking time in step 4 to about 20–30 minutes, since fresh shrimp cook faster than frozen.
Why is my sauce watery? This is usually caused by frozen spinach that wasn’t drained well, or shrimp that released extra moisture as they thawed. Let the sauce simmer uncovered on LOW for an extra 10–15 minutes to thicken, or stir in a bit more Parmesan.
Can I make this ahead of time? The sauce base through step 2 can be made a day ahead and refrigerated, then reheated in the slow cooker before adding the frozen shrimp, which helps cut down on day-of cooking time.
What can I use instead of sun-dried tomatoes? Halved cherry tomatoes or a couple tablespoons of tomato paste can work in a pinch, though you’ll lose some of the concentrated, slightly tangy flavor that sun-dried tomatoes bring.
Is this recipe spicy? No, this is a rich, savory dish rather than a spicy one — if you’d like some heat, a pinch of red pepper flakes stirred in with the garlic works well.
