There’s something about the combination of Cajun spice and a tangy tomato cream sauce that hits every note at once — smoky, savory, a little spicy, and rich enough to feel indulgent. This skillet Cajun tomato cream shrimp brings all of that together in one pan, and it’s built to work with shrimp straight from the freezer, so there’s no thawing or planning ahead required.
The sauce starts with a Cajun-seasoned base, builds in diced tomatoes for tang and body, and finishes with cream to bring everything together into something velvety and rich, with just enough heat to keep things interesting. It’s a little different from a straight cream sauce or a straight tomato sauce, landing somewhere in between — bold enough to stand on its own, but still comforting and family-friendly if you keep the heat level in check.
Since the shrimp go in frozen, this recipe is timed to let the tomatoes and Cajun seasoning build flavor first, then lets the shrimp cook gently in that base before the cream goes in at the end. The result is a dinner with real depth of flavor that still comes together in about 20 minutes from start to finish.

Ingredient Notes
Cajun seasoning blends vary quite a bit in saltiness and heat depending on the brand, so it’s worth tasting yours first, or making your own blend with paprika, garlic powder, onion powder, oregano, thyme, cayenne, and black pepper so you have full control over both. If you like a milder dish, start with less cayenne and add heat gradually; if you love spice, this recipe can easily handle more.
For the tomatoes, a can of diced tomatoes (regular or fire-roasted) works well, with fire-roasted adding an extra layer of smoky flavor that pairs especially nicely with the Cajun seasoning. Crushed tomatoes can also be used for a slightly smoother sauce, though diced tomatoes give a bit more texture throughout the dish.
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 relatively short simmer time. Heavy cream gives the richest, most stable sauce; half-and-half can be used for a lighter version, though it’s a bit more prone to separating if the heat runs too high.

Step-by-Step Instructions
- Sauté the garlic and Cajun seasoning. Heat butter or oil in a large skillet over medium heat, then add the minced garlic and Cajun seasoning, stirring for about 30–60 seconds until fragrant. Tip: cooking the seasoning briefly in the fat helps bloom the spices, giving the finished sauce a deeper, more developed flavor.
- Add the tomatoes. Stir in the diced tomatoes along with their juices and let the mixture simmer for 2–3 minutes to start building the sauce base.
- Add the frozen shrimp. Add the shrimp straight from frozen, breaking apart any large clumps, and stir gently to coat them in the tomato mixture.
- Simmer until nearly cooked through. Let the shrimp simmer in the sauce for 5–6 minutes, stirring occasionally, until they’re mostly pink and opaque. Tip: some extra liquid may pool in the pan as the shrimp thaw — that’s expected and will cook down as the sauce comes together.
- Stir in the cream. Lower the heat slightly and stir in the heavy cream, letting the sauce simmer gently for another 2–3 minutes until it thickens slightly and the shrimp are fully cooked through. Tip: keep the heat moderate here — boiling cream too hard can cause it to break instead of thickening smoothly into the tomato base.
- Finish and serve. Stir in fresh parsley and a squeeze of lemon juice, taste and adjust the Cajun seasoning, salt, or hot sauce as needed, then serve immediately over pasta, rice, or with crusty bread.

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 occasionally, or in the microwave in short bursts at reduced power, since the cream can separate if reheated too quickly or at full power.
This dish freezes reasonably well compared to some other cream-based shrimp recipes, since the tomatoes help stabilize the sauce somewhat. Freeze in an airtight container for up to 1 month, thaw overnight in the fridge, and reheat gently on the stovetop, stirring in a splash of cream to help bring the sauce back together.
Budget Note
This recipe comes out to roughly $3.50–$4.50 per serving, with frozen shrimp being the main cost driver. To stretch it further, buy shrimp in bulk frozen bags rather than small portions, and bulk up the dish with extra bell peppers or onions so you can use slightly less shrimp per serving without sacrificing how filling the meal feels.
Variations to Try
Lighter version: Swap the heavy cream for half-and-half, keeping the final simmer gentle so the lighter dairy doesn’t separate. The sauce will be a touch thinner but still full of smoky, tangy Cajun flavor.
Keto / low-carb: This recipe is naturally low-carb as written — simply serve it over cauliflower rice or steamed vegetables instead of pasta, and double-check your Cajun seasoning blend for any hidden added sugar.
Vegetable-packed version: Stir in sliced bell peppers and onions along with the garlic at the start, letting them soften as the sauce builds, for a heartier, more complete one-pan meal.
Meal-prep friendly: Portion the finished dish into individual containers with rice or pasta, and it holds up reasonably well in the fridge for a couple of days. A splash of cream when reheating helps bring 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 simmer time in step 4 to about 2–3 minutes, since they cook faster and won’t release as much extra liquid.
Why is my sauce thin? This usually happens when the liquid from the frozen shrimp and canned tomatoes isn’t given enough time to reduce. Let the sauce simmer a bit longer before adding the cream, or let it simmer uncovered for a few extra minutes after the cream goes in.
Can I make this ahead of time? The tomato and Cajun seasoning base (through step 2) can be made a day ahead and refrigerated, then reheated before adding the frozen shrimp fresh, which helps cut down on the actual cook time.
What can I use instead of heavy cream? Half-and-half works as a lighter substitute, though the sauce will be thinner and needs gentler heat to avoid separating.
Is this recipe very spicy? It’s mild-to-medium as written, with the heat mostly coming from the Cajun seasoning and any cayenne it contains. Start light and add hot sauce or extra cayenne at the end if you’d like more kick.
