Cajun Shrimp Rice – Easy One-Pan Dinner
Cajun Shrimp Rice is a one-pan dinner made with seared, Cajun-seasoned shrimp, fluffy long-grain rice, and a colorful base of onion, bell pepper, and celery. It takes about 35 minutes from start to finish and is ideal for spice lovers, busy weeknights, or anyone who wants bold, restaurant-style flavor without a sink full of pots.
Why This Recipe Works
Why You'll Love This Cajun Shrimp Rice
The trick that makes this dish work is treating the shrimp and the rice as two separate timing problems in the same pan. Shrimp only needs a couple of minutes to cook, while rice needs almost twenty — so searing the shrimp first, setting it aside, and stirring it back in at the very end is what keeps it tender instead of turning rubbery by the time the rice is done.
It's a genuinely one-pan dinner built around pantry staples: rice, broth, the Cajun holy trinity of onion, bell pepper, and celery, and a spice blend you probably already have. That makes it an easy repeat on a busy week, and it's flexible enough to take a handful of sliced andouille sausage or a can of diced tomatoes if that's what you're in the mood for.
Ingredients
- 1 lb large shrimp, peeled and deveined
- 2 tbsp Cajun seasoning, divided
- 1 tbsp olive oil
- 2 tbsp unsalted butter (or additional olive oil for dairy-free)
- 1 small yellow onion, diced
- 1 red bell pepper, diced
- 2 celery stalks, diced
- 3 garlic cloves, minced
- 1 cup long-grain white rice
- 2 cups chicken broth
- 1 tsp smoked paprika
- 1/2 tsp dried thyme
- 1/4 tsp cayenne pepper (optional, for extra heat)
- 1 small lemon, juiced, plus wedges for serving
- 2 tbsp fresh parsley, chopped
Instructions
- Pat the shrimp dry with paper towels, then toss with 1 tablespoon of the Cajun seasoning.
- Heat the olive oil in a large skillet or deep pan over medium-high heat. Add the shrimp in a single layer and sear for 1-2 minutes per side, until just opaque. Remove to a plate — they'll finish cooking later.
- Melt the butter in the same skillet. Add the onion, bell pepper, and celery, and cook, stirring occasionally, until softened, about 4-5 minutes.
- Stir in the garlic and cook until fragrant, about 30 seconds.
- Add the rice and stir to coat it in the butter and vegetables, toasting it for 1-2 minutes until it smells nutty.
- Pour in the chicken broth and stir in the remaining 1 tablespoon Cajun seasoning, smoked paprika, thyme, and cayenne pepper, if using. Bring to a boil.
- Reduce the heat to low, cover, and simmer undisturbed for 15-18 minutes, until the rice is tender and the liquid is absorbed. Resist lifting the lid to stir — that lets steam escape and can leave the rice underdone.
- Remove from the heat and let it rest, covered, for 5 minutes so the moisture redistributes.
- Fluff the rice with a fork, then stir in the seared shrimp and lemon juice, tossing gently until the shrimp is warmed through and cooked to opaque all the way through.
- Top with fresh parsley and serve with lemon wedges.
Ingredient Substitutions
No large shrimp? Use medium shrimp instead — just reduce the sear time to about 1 minute per side so they don't overcook when stirred back in.
No fresh Cajun holy trinity? Use 1 1/2 cups of a frozen onion-pepper-celery blend instead — thaw and pat dry first so you're not adding extra liquid to the pan.
No long-grain white rice? Use Jasmine rice instead — it's aromatic and cooks in about the same time. Basmati also works, but check it a minute or two early since it can cook slightly faster.
No chicken broth? Use vegetable broth or water with an extra pinch of salt instead — the flavor will be a little less rich, but the rice will still cook properly.
No fresh garlic? Use 1/2 teaspoon garlic powder instead — stir it in with the smoked paprika rather than sautéing it separately.
Want it milder? Skip the cayenne and use a mild Cajun seasoning blend, then let people add hot sauce at the table.
Want it saucier? Stir in a drained can of diced tomatoes along with the shrimp at the end.
Storage & Reheating
Store leftover Cajun shrimp rice in an airtight container in the refrigerator for up to 3 days. Freezing isn't recommended — the shrimp texture suffers noticeably once thawed, and the rice can turn mushy.
Reheat in a skillet over medium-low heat with a splash of broth or water to loosen the rice, stirring gently just until warmed through. The microwave works too — cover loosely and reheat in short bursts, stirring in between so the shrimp doesn't overcook.

How to Make Cajun Rice Fluffy
Fluffy rice comes down to ratio and patience more than anything else.
- Stick to the 1 cup rice to 2 cups broth ratio — too much liquid leaves rice gummy, too little leaves it undercooked.
- Keep the lid on during the simmer. Lifting it to check lets steam escape and can leave the rice unevenly cooked.
- Avoid stirring while it simmers — this releases starch and makes the rice stickier.
- Let it rest, covered, for 5 minutes off the heat before fluffing. This lets the last bit of moisture redistribute evenly.
- If the rice is still firm after resting, add a splash more broth, cover, and simmer a few more minutes.
- If it turns out too wet, simmer uncovered for a minute or two to let the extra liquid cook off.
How to Keep the Shrimp Tender
- Pat shrimp completely dry before seasoning — excess moisture keeps it from searing properly.
- Sear over medium-high heat just until opaque, about 1-2 minutes per side, then pull it out of the pan.
- Add it back in only at the very end, off the direct heat of the simmer, so it reheats gently instead of overcooking.
- Look for an opaque, C-shaped curl as your doneness cue — a tight "O" shape usually means it's gone too far.
Can I Use Frozen Shrimp?
Yes. Thaw it in the fridge overnight, or run it under cold water for a quicker thaw, then pat it thoroughly dry before seasoning. Skipping the dry-off step is the most common reason a shrimp skillet turns watery.
Adjusting the Spice Level
- Mild: Skip the cayenne and use a mild or salt-free Cajun blend.
- Medium: Use the recipe as written with a standard Cajun seasoning.
- Spicy: Add the full 1/4 teaspoon cayenne, and pass hot sauce at the table.
Variations
- With andouille sausage: Brown 8 oz sliced sausage before searing the shrimp, then stir both back in at the end.
- Tomato version: Stir in a drained can of diced tomatoes along with the shrimp for a saucier, Creole-style finish.
- Extra vegetables: Add a handful of frozen corn or diced zucchini along with the onion, pepper, and celery.
- Extra spice: Finish with a dash of hot sauce or extra cayenne.
What to Serve With Cajun Shrimp Rice
- Crusty bread or cornbread
- A simple green salad
- Steamed green beans or okra
- Extra lemon wedges and hot sauce on the side
Frequently Asked Questions
What kind of rice is best for Cajun shrimp rice?
Long-grain white rice is the most reliable choice — it stays separate and fluffy rather than sticky. Jasmine rice works as an aromatic swap with a similar cook time. Basmati also works but can cook slightly faster, so start checking it a couple of minutes early. Brown rice needs a different liquid ratio and cook time, so don't substitute it 1:1.
Can I use frozen shrimp?
Yes. Thaw it first if you can — overnight in the fridge or under cold running water — then pat it very dry before seasoning. Skipping this step adds extra water to the skillet and can leave your rice soggy. If you're short on time, a quick cold-water thaw works fine.
When should I add the shrimp to the rice?
Sear it briefly at the start for flavor, then set it aside and stir it back in at the very end, after the rice has finished simmering and resting. Shrimp cooks in just a couple of minutes, so adding it too early — or leaving it in while the rice simmers — is the main reason shrimp turns rubbery.
How do I keep the shrimp from getting rubbery?
Sear it quickly over medium-high heat just until it turns opaque, then pull it out of the pan before it's fully done. It finishes cooking gently when you stir it back into the hot rice at the end, which keeps it tender instead of overcooked.
Can I make this less spicy for kids?
Yes. Leave out the cayenne pepper entirely and use a mild or salt-free Cajun seasoning blend instead of a hot one. You can always add hot sauce or extra cayenne to individual plates afterward so everyone can adjust their own heat level.
Can I add andouille sausage?
Yes — slice about 8 ounces and brown it in the skillet before you sear the shrimp, then set it aside with the shrimp. Stir both back in together at the end. The rendered fat also adds extra flavor to the vegetables and rice.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over medium-low heat with a splash of broth or water to loosen the rice, or microwave in short bursts, stirring in between so the shrimp doesn't overcook.
