Cajun Shrimp Sheet Pan Dinner

This Cajun shrimp sheet pan dinner is one of those meals I make when I want the protein and vegetables handled on the same pan. The asparagus gets a head start in the oven, then the shrimp goes on for the last few minutes so everything finishes together.

The Cajun seasoning gives the shrimp plenty of bold flavor, while the roasted asparagus and fresh lemon keep the dinner from feeling heavy. It's simple, a little spicy, and easy to serve straight from the sheet pan or with rice when you want something more filling.

I roast the asparagus for 12 minutes before adding the shrimp. That timing gave the asparagus enough time to start browning while still keeping it tender by the time the shrimp finished cooking.

Quick Success Tips

• Give the asparagus the full 12-minute head start. That gives it time to begin softening and browning before the shrimp goes onto the pan.
• Start checking the shrimp at 6 minutes. Large shrimp cook quickly, and I take them out as soon as they are opaque and cooked through.
• Keep everything in a single layer. The asparagus and shrimp roast better when they have room on the pan.
• Taste your Cajun seasoning first. Some blends are much saltier or spicier than others, so I keep the extra salt light until I know what the blend needs.
• Finish with lemon after roasting. The fresh lemon wakes up the Cajun flavor without adding extra moisture while the shrimp cook.

Why This Recipe Works

The asparagus and shrimp need different amounts of time, so I don't put them on the pan together from the beginning.

The asparagus roasts for 12 minutes first, then the shrimp goes on for another 6-8 minutes. That gives the asparagus the time it needs without leaving the shrimp in the oven too long.

Using Cajun seasoning on both parts of the dinner also keeps the whole sheet pan connected instead of tasting like seasoned shrimp with plain vegetables on the side.

Ingredients You'll Need

Find the full ingredient list and exact measurements in the recipe card below.

• Large shrimp: Use raw, peeled and deveined shrimp. Thaw frozen shrimp completely and pat them dry before seasoning.
• Asparagus: Use one bunch with the woody ends trimmed. Choose stalks of similar thickness so they roast evenly.
• Olive oil: You'll season the asparagus and shrimp separately, using oil for both.
• Cajun seasoning: Use a blend you already enjoy. Heat and salt levels vary by brand.
• Garlic powder: Adds garlic flavor to the shrimp without extra chopping.
• Salt and black pepper: Season the asparagus along with the Cajun blend.
• Fresh lemon juice: Goes over the cooked shrimp and asparagus just before serving. Serve with lemon wedges.

How to Make Cajun Shrimp Sheet Pan Dinner

1. Roast the asparagus first

Preheat the oven to 425°F. Toss the asparagus with its olive oil, Cajun seasoning, salt, and pepper. Spread it in a single layer on a large sheet pan.

Roast for 12 minutes, until it begins to soften and brown.

2. Season the shrimp

While the asparagus roasts, toss the shrimp with olive oil, Cajun seasoning, and garlic powder.

3. Add the shrimp to the pan

Remove the sheet pan from the oven, add the shrimp, and spread everything into an even layer. Keep the shrimp from piling on top of each other.

Return the pan to the oven for 6-8 minutes, until the shrimp are opaque and cooked through. I start checking at 6 minutes because they can overcook quickly.

4. Finish with lemon

Squeeze the fresh lemon juice over the shrimp and asparagus and serve right away, with extra lemon wedges as desired.

Helpful Tips

• Dry the asparagus after washing. Water clinging to the stalks can leave the pan wet and make browning harder.
• Check a thicker asparagus stalk before adding the shrimp. It should be beginning to soften. Thin stalks can brown faster, so use the texture as well as the timer.
• Leave room for the shrimp. Use a pan large enough to hold both the asparagus and shrimp in a single layer once everything is added.

What to Serve With Cajun Shrimp Sheet Pan Dinner

The shrimp and asparagus can be dinner on their own. For a more filling plate, spoon them over Instant Pot brown rice or quinoa. Both work well with the Cajun seasoning and lemon.

I usually keep the side simple here. Leftover rice or a piece of bread makes this an easy dinner without starting another recipe.

How to Store and Reheat

Refrigerate leftovers in a shallow, airtight container within 2 hours of cooking, or within 1 hour when the temperature is above 90°F. Keep refrigerated for up to 3-4 days.

Reheat a portion in a covered skillet over low heat with a small splash of water, until it reaches 165°F. Remove it from the heat once reheated; continuing to cook will make the shrimp tougher.

I prefer making this fresh and using the leftovers for lunch rather than cooking several days of shrimp at once.
