How to Make Cajun Shrimp with Mashed Potatoes and Roasted Broccolini Recipe
Step 1: Prepare the Mashed Potatoes
Start by peeling and cutting the russet potatoes into even chunks so they cook uniformly. Boil them in salted water until they are fork-tender, about 15 minutes. Drain well, then mash with butter, heavy cream, garlic powder, salt, and pepper until you get a smooth, creamy consistency. Set aside and let the rich flavors meld while you move on to the next steps.
Step 2: Roast the Broccolini
Preheat your oven to 400°F (200°C). Toss the broccolini with a tablespoon of olive oil, salt, and pepper, making sure every stalk is well coated. Lay them out in a single layer on a baking sheet and roast for 15 to 20 minutes. They should become tender with slightly charred edges, which brings out a wonderful natural sweetness. If you love a hint of zest, sprinkle lemon zest over the broccolini right before serving for an extra fresh note.
Step 3: Cook the Cajun Shrimp
In a mixing bowl, coat the peeled and deveined shrimp evenly with olive oil, Cajun seasoning, paprika, garlic powder, onion powder, cayenne pepper, salt, and pepper. Heat a skillet over medium-high heat and cook the shrimp for 2 to 3 minutes per side. You’ll know they’re ready when they turn pink and opaque, with a slight crisp on the edges that’s just irresistible.
Step 4: Assemble and Serve
It’s time to bring everything together! On each plate, spread a generous bed of the creamy mashed potatoes, lay down a handful of the spicy Cajun shrimp, and add a serving of the roasted broccolini. This layered presentation not only looks inviting but ensures every bite hits all the best flavors and textures you’ve prepared.
How to Serve Cajun Shrimp with Mashed Potatoes and Roasted Broccolini Recipe
Garnishes
Fresh garnishes really elevate this dish. Try sprinkling chopped parsley or cilantro for a burst of color and freshness that cuts through the richness. Lemon wedges on the side are a perfect complement, allowing each person to add a pop of brightness that balances the spicy shrimp beautifully.
Side Dishes
Though this Cajun Shrimp with Mashed Potatoes and Roasted Broccolini Recipe shines all on its own, you can add a simple side salad with a light vinaigrette or some crusty garlic bread for crunch and to soak up the delicious flavors. A chilled white wine or sparkling water with lemon pairs wonderfully here as well.
Creative Ways to Present
For a special occasion, consider serving the shrimp in small individual cast iron skillets atop the mashed potatoes, with broccolini artfully arranged on the side. Alternatively, stack the mashed potatoes in a ring shape and heap the shrimp in the center, draping broccolini around it—an eye-catching dinner plate that will surely impress your dinner guests.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer your leftover Cajun Shrimp with Mashed Potatoes and Roasted Broccolini Recipe into airtight containers. Store in the refrigerator for up to 3 days to ensure maximum freshness without losing the dish’s vibrant flavors.
Freezing
You can freeze the mashed potatoes and shrimp separately for best results. Store mashed potatoes in a freezer-safe container and the cooked shrimp in a sealed bag or container. Both should be used within 1 to 2 months. Roasted broccolini is best enjoyed fresh but can be frozen as well though the texture may soften.
Reheating
Reheat mashed potatoes gently on the stovetop or in a microwave, stirring in a splash of cream or milk to bring back creaminess. Warm the shrimp quickly in a pan over medium heat, being careful not to overcook. Reheat broccolini in the oven or microwave until just warm to preserve its tender crunch.

A chilled Sauvignon Blanc or a crisp Chardonnay complements the spicy and creamy elements beautifully, balancing out the flavors without overwhelming the seafood.
