Grilling shrimp on a pellet grill is a fantastic way to impart a smoky flavor and create a delicious, quick meal. However, achieving perfectly cooked shrimp requires understanding the right cooking time and temperature. Overcooked shrimp are rubbery and unpleasant, while undercooked shrimp pose a health risk. This guide provides everything you need to know to master shrimp grilling on your pellet grill.
Understanding Shrimp and Pellet Grills
Before diving into cooking times, let’s understand the basics of shrimp and pellet grills. Different shrimp sizes and the unique characteristics of pellet grills play a significant role in the final result.
Shrimp Size Matters
Shrimp are categorized by size, usually denoted by a number indicating how many shrimp make up a pound. For example, “16/20” shrimp means there are 16 to 20 shrimp per pound. The size significantly impacts the cooking time. Smaller shrimp cook faster than larger ones. Common shrimp sizes include:
- Jumbo (U/12, 13/15): Extra large shrimp, usually used for shrimp cocktails or grilled on skewers.
- Extra Large (16/20, 21/25): Excellent for grilling, offering a good balance of size and cook time.
- Large (26/30, 31/40): A versatile size that works well for various recipes, including grilling.
- Medium (41/50, 51/60): Smaller shrimp often used in pasta dishes or salads.
- Small (61/70, 71/90): Generally not ideal for grilling due to their small size and tendency to overcook quickly.
Pellet Grill Peculiarities
Pellet grills offer precise temperature control and infuse food with wood-fired flavor. Unlike gas or charcoal grills, pellet grills use wood pellets as fuel, providing consistent heat and a smoky taste. The type of wood pellet also influences the flavor profile of your shrimp. Popular choices include:
- Hickory: Delivers a strong, smoky flavor.
- Mesquite: Offers a bold, earthy taste.
- Apple: Provides a sweet, mild smoky flavor.
- Cherry: Adds a subtle, fruity note.
Understanding your pellet grill’s temperature range and how it distributes heat is crucial for consistent cooking. Always preheat the grill thoroughly before adding the shrimp.
Preparing Shrimp for the Grill
Proper preparation is key to grilling delicious shrimp. This includes choosing the right shrimp, cleaning them, and deciding whether to grill them with the shell on or off.
Selecting Fresh or Frozen Shrimp
Fresh shrimp should have a firm texture, a translucent appearance, and a mild, sea-like smell. Avoid shrimp that smell fishy or ammonia-like, as these are signs of spoilage.
Frozen shrimp are a convenient alternative to fresh shrimp and can be just as good if thawed properly. Thaw frozen shrimp in the refrigerator overnight or place them in a sealed bag in cold water for about 30 minutes to an hour. Never thaw shrimp at room temperature, as this can encourage bacterial growth.
Cleaning and Deveining Shrimp
Rinse the shrimp under cold water. To devein, use a small, sharp knife to make a shallow cut along the back of the shrimp and remove the dark vein. While not always necessary, deveining improves the shrimp’s texture and appearance.
Shell On or Off?
Grilling shrimp with the shell on helps to retain moisture and flavor. The shell acts as a protective barrier, preventing the shrimp from drying out on the grill. However, it can be slightly more challenging to determine when the shrimp are fully cooked.
Grilling shrimp with the shell off allows for quicker cooking and easier access for seasoning. However, be mindful of overcooking, as shell-less shrimp tend to dry out more quickly.
Marinating for Flavor
Marinating shrimp adds flavor and helps to keep them moist during grilling. A simple marinade can consist of olive oil, lemon juice, garlic, herbs, and spices. Marinate the shrimp for at least 30 minutes, but no more than a few hours, as the acid in the marinade can break down the shrimp’s texture if left for too long.
Optimal Grilling Temperatures and Times
The ideal grilling temperature and time for shrimp on a pellet grill depend on the shrimp size and whether they are grilled with the shell on or off.
Recommended Grilling Temperatures
Aim for a medium-high heat, around 350-400°F (175-200°C), for grilling shrimp on a pellet grill. This temperature allows the shrimp to cook quickly without drying out.
Grilling Times by Shrimp Size and Shell
These are general guidelines; always check for doneness visually. Shrimp are done when they turn pink and opaque.
Shell-On Shrimp:
- Jumbo (U/12, 13/15): 4-6 minutes total (2-3 minutes per side)
- Extra Large (16/20, 21/25): 3-5 minutes total (1.5-2.5 minutes per side)
- Large (26/30, 31/40): 3-4 minutes total (1.5-2 minutes per side)
Shell-Off Shrimp:
- Jumbo (U/12, 13/15): 3-5 minutes total (1.5-2.5 minutes per side)
- Extra Large (16/20, 21/25): 2-4 minutes total (1-2 minutes per side)
- Large (26/30, 31/40): 2-3 minutes total (1-1.5 minutes per side)
Tips for Perfect Grilling
- Preheat the grill: Ensure the pellet grill is fully preheated to the desired temperature before adding the shrimp.
- Use a grill basket or skewers: To prevent shrimp from falling through the grates, use a grill basket or thread them onto skewers. Skewers also make it easier to flip the shrimp.
- Don’t overcrowd the grill: Leave enough space between the shrimp for even cooking.
- Flip only once: For best results, flip the shrimp only once during grilling.
- Watch for doneness: Shrimp cook quickly, so keep a close eye on them. They are done when they turn pink and opaque.
- Use a meat thermometer: To ensure the shrimp are fully cooked, use a meat thermometer to check the internal temperature. Shrimp are safe to eat when they reach an internal temperature of 145°F (63°C).
- Rest briefly: Let the shrimp rest for a minute or two after grilling to allow the juices to redistribute.
Troubleshooting Common Issues
Even with the best preparation, grilling shrimp can sometimes present challenges. Here are some solutions to common problems:
Shrimp Sticking to the Grill
- Ensure the grill grates are clean and well-oiled.
- Use a high-heat cooking oil, such as canola or grapeseed oil, to prevent sticking.
- Don’t try to flip the shrimp too soon. Wait until they have developed a slight sear on the bottom.
Overcooked, Rubbery Shrimp
- Reduce the grilling time.
- Use a lower grilling temperature.
- Consider grilling the shrimp with the shell on to help retain moisture.
- Avoid overcrowding the grill, which can lower the temperature and lead to uneven cooking.
Undercooked Shrimp
- Increase the grilling time.
- Ensure the grill is properly preheated.
- Use a meat thermometer to check the internal temperature.
- If the shrimp are very thick, consider butterflying them to ensure even cooking.
Unevenly Cooked Shrimp
- Make sure the shrimp are all the same size for uniform cooking.
- Spread the shrimp evenly across the grill surface.
- Flip the shrimp halfway through the cooking time.
- Check for hot spots on your grill and adjust the placement of the shrimp accordingly.
Serving Suggestions and Recipes
Grilled shrimp are incredibly versatile and can be served in various ways. Here are a few ideas:
- Shrimp Tacos: Serve grilled shrimp in warm tortillas with your favorite taco toppings, such as shredded cabbage, pico de gallo, and avocado cream.
- Shrimp Skewers: Thread grilled shrimp onto skewers with vegetables like bell peppers, onions, and zucchini.
- Shrimp Salad: Add grilled shrimp to a refreshing salad with mixed greens, tomatoes, cucumbers, and a light vinaigrette.
- Shrimp Scampi: Toss grilled shrimp with pasta, garlic, butter, white wine, and Parmesan cheese for a quick and easy scampi.
- Shrimp Cocktail: Serve chilled grilled shrimp with cocktail sauce for a classic appetizer.

Cold Smoking Shrimp
Cold smoking shrimp before grilling imparts a deeper smoky flavor without fully cooking them. Use a smoke tube or pellet smoker attachment to cold smoke shrimp at a low temperature (below 90°F or 32°C) for 1-2 hours. After cold smoking, grill the shrimp as usual.
Plank Grilling Shrimp
Grilling shrimp on a cedar plank adds a subtle woody flavor and helps to keep them moist. Soak the cedar plank in water for at least 30 minutes before placing it on the grill. Arrange the shrimp on the plank and grill until cooked through.
Using Different Wood Pellets
Experiment with different wood pellet flavors to find your favorite combination with shrimp. For example, try using pecan pellets for a nutty flavor or alder pellets for a mild, balanced smoke.
Reverse Searing Shrimp
For extra-tender shrimp, try reverse searing. First, cook the shrimp at a low temperature (around 225°F or 107°C) until they are almost done. Then, crank up the heat to high and sear the shrimp for a minute or two per side to create a caramelized crust.

What type of shrimp is best for grilling on a pellet grill?
Large or jumbo shrimp are generally the best choice for grilling on a pellet grill. Their size prevents them from falling through the grates easily and makes them easier to handle. Look for shrimp labeled 16/20 or 21/25, which indicates the number of shrimp per pound, as these sizes tend to stay moist and flavorful during the grilling process.
Shell-on shrimp are often preferred, as the shell helps protect the delicate flesh from direct heat, resulting in a more tender and juicy outcome. However, peeled and deveined shrimp can also be used; just be sure to keep a close eye on them and adjust the cooking time to prevent overcooking. Marinating peeled shrimp before grilling can help them retain moisture and enhance their flavor.
What temperature should I set my pellet grill to for cooking shrimp?
The ideal temperature for cooking shrimp on a pellet grill is between 350°F and 400°F (175°C and 205°C). This temperature range allows for relatively quick cooking, preventing the shrimp from drying out while still imparting a nice smoky flavor from the wood pellets. It’s a balance between achieving a good sear and maintaining a moist interior.
If you are using a marinade with high sugar content, it’s wise to keep the temperature closer to 350°F to avoid burning the marinade. Conversely, if you desire a more pronounced char, you can briefly raise the temperature to 400°F for the last minute or two of cooking, but monitor closely to prevent the shrimp from becoming rubbery.
How long does it take to cook shrimp on a pellet grill?
Shrimp typically cook very quickly on a pellet grill. Depending on their size and the grill temperature, they usually take between 4 and 8 minutes to cook. The goal is to cook them until they turn pink and opaque, with a slight curve. Overcooked shrimp become rubbery and lose their desirable texture.
It is crucial to check the shrimp frequently, especially if you are using smaller shrimp or a higher grill temperature. Flip the shrimp halfway through the cooking time to ensure even cooking on both sides. Use a meat thermometer if you’re unsure; the internal temperature should reach 145°F (63°C).
Should I marinate the shrimp before grilling?
Marinating shrimp before grilling is highly recommended as it adds flavor and helps keep them moist during the cooking process. A good marinade typically consists of oil, an acid (like lemon juice or vinegar), herbs, and spices. Marinate the shrimp for at least 30 minutes, but no more than 2 hours, in the refrigerator.
Over-marinating can cause the shrimp to become mushy, especially if the marinade contains a strong acid. Be sure to discard the marinade after removing the shrimp to avoid any potential cross-contamination. Patting the shrimp dry before placing them on the grill will help achieve a better sear.
How do I prevent shrimp from sticking to the grill grates?
Preventing shrimp from sticking to the grill grates is essential for easy cooking and preventing them from tearing. Ensure the grill grates are clean and well-oiled before placing the shrimp on them. You can use a high-heat cooking oil, such as canola or vegetable oil, applied with a brush or spray.
Also, make sure the grill is properly preheated before adding the shrimp. The hot grates will help create a sear, which will reduce the likelihood of sticking. Avoid moving the shrimp around too much during the initial cooking phase. Give them a chance to develop a slight crust before attempting to flip them.
What type of wood pellets are best for grilling shrimp?
Lighter wood pellets, such as apple, alder, cherry, or pecan, are generally preferred for grilling shrimp. These woods impart a subtle, sweet, and smoky flavor that complements the delicate taste of the shrimp without overpowering it. Stronger wood flavors like hickory or mesquite might be too intense for shrimp.
Experimenting with different wood pellet blends can also yield interesting results. For example, a blend of apple and alder can provide a balanced smoky and slightly sweet flavor. Consider the other ingredients in your dish when selecting your wood pellets to ensure the flavors harmonize well.
How do I know when the shrimp are done cooking on the pellet grill?
The easiest way to determine if shrimp are done cooking on the pellet grill is by observing their appearance. Cooked shrimp will turn pink and opaque throughout, with a slight curve in their shape. Avoid overcooking, as this will result in rubbery and tough shrimp.
You can also use a meat thermometer to ensure the internal temperature reaches 145°F (63°C). Insert the thermometer into the thickest part of the shrimp. Remove the shrimp from the grill as soon as they reach this temperature to prevent overcooking. Carryover cooking will continue to raise the temperature slightly after they are removed from the heat.
