Ingredient List

For the Shrimp

• 1 lb large shrimp, peeled and deveined
• 1 tbsp olive oil
• 1 tsp Cajun seasoning
• 1/2 tsp paprika
• Salt and pepper, to taste

For the Sauce

• 1 tbsp butter
• 1 small onion, finely chopped
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 can (10 oz) Rotel diced tomatoes with green chilies
• 1/2 cup heavy cream
• 1/2 cup shredded cheddar cheese
• 1/4 cup grated Parmesan cheese
• 2 cloves garlic, minced
• 1/2 tsp crushed red pepper flakes (optional, for extra heat)

For Serving (Optional)

• Cooked rice, pasta, or crusty bread
• Fresh parsley, chopped, for garnish

Ingredient Notes

• I always use large, fresh shrimp if I can—it cooks perfectly and stays tender. Frozen works too, just thaw it completely.
• Don’t skip the Rotel diced tomatoes! They give the sauce that signature kick and balance the creaminess beautifully.
• Cajun seasoning is key here—my go-to brand adds just the right spice without being overpowering.
• Cheese blend is important: cheddar for gooey creaminess, Parmesan for that savory depth. It makes all the difference in the sauce.
• Bell peppers aren’t just for color—they add a little crunch and sweetness that pairs perfectly with the shrimp.

Kitchen Equipment Needed

• Large Skillet or Sauté Pan – Perfect for cooking shrimp evenly and simmering the creamy Cajun shrimp sauce. I love using my heavy-bottomed skillet because it distributes heat so well.
• Cutting Board & Sharp Knife – Essential for slicing bell peppers and chopping onions quickly. A good knife makes prep feel effortless.
• Measuring Cups & Spoons – For accurate portions of cream, cheese, and spices—no guessing needed.
• Wooden Spoon or Silicone Spatula – Ideal for stirring the sauce without scratching your pan. I personally use a silicone spatula for easy scraping.
• Colander (if serving with pasta or rice) – Makes draining cooked pasta or rinsing vegetables quick and mess-free.

Instructions

1. Prepare the Shrimp

• Pat the shrimp dry with paper towels—this helps them sear nicely.
• In a bowl, toss shrimp with Cajun seasoning, paprika, salt, and pepper until evenly coated.
• Pro tip: Don’t overcrowd the pan when cooking shrimp; it helps them brown instead of steaming.

2. Cook the Shrimp

• Heat olive oil in a large skillet over medium-high heat.
• Add the seasoned shrimp and cook for 2–3 minutes per side, until pink and opaque.
• Remove shrimp from the skillet and set aside on a plate.

3. Sauté the Vegetables

• In the same skillet, melt butter over medium heat.
• Add onions and bell peppers, sautéing for 3–4 minutes until softened.
• Stir in minced garlic and cook for another 30 seconds until fragrant.

4. Make the Creamy Cajun Shrimp Sauce

• Pour in the Rotel diced tomatoes (with juices) and stir to combine.
• Reduce heat to medium-low and slowly add the heavy cream, stirring continuously.
• Sprinkle in cheddar and Parmesan cheese, stirring until melted and smooth.
• Pro tip: Keep the sauce on low heat while adding cheese to prevent it from clumping.
• Add crushed red pepper flakes if you like an extra kick.

5. Combine Shrimp and Sauce

• Return cooked shrimp to the skillet, gently tossing to coat with the creamy Cajun shrimp sauce.
• Simmer for 2–3 minutes so the flavors meld together.

6. Serve and Garnish

• Spoon the creamy shrimp and vegetable mixture over cooked rice, pasta, or alongside crusty bread.
• Garnish with chopped fresh parsley for color and freshness.
• Enjoy immediately while warm!

Tips and Tricks for Success

• Don’t Overcook the Shrimp – Shrimp cook quickly, so keep an eye on them. Overcooked shrimp become rubbery.
• Use Fresh Ingredients When Possible – Fresh bell peppers and shrimp make a noticeable difference in flavor and texture.
• Season in Layers – Season the shrimp first and taste the sauce before serving; adjust salt and spice as needed.
• Keep the Sauce Smooth – Stir the cheese in slowly over low heat to avoid clumps in the creamy Cajun shrimp sauce.
• Serve Immediately – This dish is best enjoyed fresh, as the shrimp can release water if left to sit too long, thinning the sauce.

Ingredient Substitutions and Variations

• Shrimp – You can swap shrimp for scallops, chicken, or even firm white fish for a different Cajun seafood twist.
• Cheese – Try Monterey Jack or pepper jack for a creamier, slightly spicier sauce.
• Rotel Diced Tomatoes – Regular diced tomatoes work if you don’t have Rotel; add a pinch of cayenne for extra heat.
• Bell Peppers – Swap with orange or green bell peppers, or add a handful of chopped zucchini for variety.
• Cream – Half-and-half or coconut milk can be used for a lighter or dairy-free option.

Serving Suggestions

• I love serving this creamy Cajun shrimp over a bed of fluffy white rice—it soaks up all the sauce beautifully.
• Spoon it over fettuccine or your favorite pasta for a comforting Cajun shrimp dinner that feels indulgent but easy.
• Pair it with garlic bread and a crisp green salad—it balances the richness perfectly and adds a fresh crunch.
• For a low-carb option, serve it over sautéed zucchini noodles or cauliflower rice for a lighter twist.
• It also works great as a filling for soft tortillas or wraps, turning it into a fun, handheld Cajun shrimp meal.

Storage and Reheating Instructions

• Refrigerate: Store leftovers in an airtight container for up to 2 days.
• Freeze: Not ideal for freezing due to the cream, but if needed, freeze the shrimp and sauce separately for up to 1 month.
• Reheat on Stovetop: Gently warm over low heat, stirring occasionally to keep the creamy sauce smooth.
• Microwave: Cover with a microwave-safe lid and heat in 30-second intervals, stirring in between, to avoid overcooking the shrimp.
• Tip: Add a splash of cream or milk while reheating to refresh the sauce and maintain its richness.
