Grilling scallops requires a very hot, clean grate and a quick cook time to achieve those desirable caramelized marks. If you have ever wondered how to cook scallops on the grill, you are in the right place. This guide will walk you through every step, from picking the right scallops to serving them perfectly.
Scallops are delicate, but grilling them is surprisingly simple. The key is to avoid overcooking, which makes them rubbery. With a few tips, you can get restaurant-quality results at home.
Why Grill Scallops?
Grilling adds a smoky flavor that you cannot get from pan-searing. The high heat creates a beautiful crust while keeping the inside tender and sweet. It is also a fast cooking method, perfect for busy weeknights or summer gatherings.
Plus, grilling scallops is healthier than frying. You use minimal oil, and the scallops cook in their own natural juices. It is a win-win for flavor and nutrition.
Choosing The Right Scallops
Not all scallops are the same. For grilling, you want large, dry-packed sea scallops. Wet scallops have been treated with a solution that makes them waterlogged, so they won’t sear properly.
Dry Vs. Wet Scallops
Dry scallops are untreated and have a natural, sweet flavor. They brown beautifully on the grill. Wet scallops are soaked in a phosphate solution to preserve moisture, but this makes them taste bland and prevents browning.
Look for scallops that are off-white or pale beige. Avoid any that look bright white or have a milky liquid in the package. Ask your fishmonger for dry-packed scallops specifically.
Size Matters
Large sea scallops (about 10-20 per pound) are best for grilling. They are thick enough to hold up to the heat without falling apart. Smaller bay scallops are too delicate and will likely fall through the grates.
If you can only find medium scallops, use a grill basket or skewers to prevent them from slipping.
How To Cook Scallops On The Grill
Now we get to the main event. Follow these steps for perfectly grilled scallops every time.
Step 1: Preheat The Grill
Start with a clean grill grate. Scrub it well with a wire brush to remove any residue from previous cooks. Then, preheat your grill to high heat, around 450-500°F (230-260°C).
A hot grate is essential for getting those nice sear marks. If the grill is not hot enough, the scallops will stick and steam instead of searing.
Step 2: Prepare The Scallops
Pat the scallops dry with paper towels. This is crucial because any moisture will prevent browning. Remove the small side muscle if it is still attached—it is tough and chewy.
Season the scallops simply. A light drizzle of olive oil, salt, and pepper is all you need. You can add garlic powder or paprika for extra flavor, but keep it minimal.
Step 3: Oil The Grate
Right before placing the scallops on the grill, oil the grates. Use a pair of tongs to hold a paper towel dipped in vegetable oil and rub it over the grates. This prevents sticking.
Be careful not to use too much oil, or it will cause flare-ups. A light coating is enough.
Step 4: Grill The Scallops
Place the scallops on the hot grill, flat side down. Leave space between each one so they cook evenly. Do not move them for 2-3 minutes.
You will know they are ready to flip when they release easily from the grate. If they stick, they need more time. Flip them once and cook for another 2-3 minutes.
The scallops are done when they are opaque in the center and have a golden-brown crust. Overcooking makes them rubbery, so keep an eye on them.
Step 5: Rest And Serve
Remove the scallops from the grill and let them rest for a minute. This allows the juices to redistribute. Serve immediately with a squeeze of lemon or a drizzle of herb butter.
Grilled scallops pair well with salads, rice, or grilled vegetables. They are also great on their own as an appetizer.
Common Mistakes To Avoid
Even experienced cooks can mess up scallops. Here are the most common pitfalls and how to avoid them.
Overcooking
Scallops cook very fast. Overcooking turns them into rubbery, flavorless discs. Aim for an internal temperature of 115-120°F (46-49°C) for medium-rare. They will continue to cook slightly after removal.
Using Wet Scallops
As mentioned, wet scallops are a disaster on the grill. They release water, which steams them and prevents browning. Always choose dry-packed scallops for grilling.
Not Drying Thoroughly
Moisture is the enemy of a good sear. Pat the scallops dry with paper towels and let them sit at room temperature for a few minutes before grilling. This helps them brown better.
Moving Them Too Early
When you first place scallops on the grill, they will stick. Resist the urge to move them. Once they develop a crust, they will release naturally. Forcing them will tear the meat.
Flavor Variations
Scallops are a blank canvas for flavors. Here are some simple ways to change things up.
Garlic Butter Scallops
Melt butter with minced garlic and brush it on the scallops during the last minute of grilling. Be careful, as butter can cause flare-ups. Use a low flame or move the scallops to a cooler part of the grill.
Spicy Cajun Scallops
Mix paprika, cayenne, garlic powder, and oregano. Coat the scallops with this spice blend before grilling. The heat pairs wonderfully with the sweet scallop meat.
Lemon Herb Scallops
Marinate scallops in lemon juice, olive oil, and fresh herbs like parsley or thyme for 15 minutes before grilling. Do not marinate longer, as the acid can start to cook the scallops.
Bacon-Wrapped Scallops
Wrap each scallop with a half slice of bacon and secure with a toothpick. Grill until the bacon is crispy and the scallop is cooked through. This is a classic appetizer that always impresses.
Equipment You Will Need
You do not need fancy tools, but a few items make the job easier.
- Grill: Gas or charcoal works fine. Charcoal adds more smoky flavor.
- Tongs: Long-handled tongs for flipping scallops without burning your hands.
- Grill basket: Useful for smaller scallops or if you are worried about them falling through the grates.
- Skewers: Metal or wooden skewers for threading scallops. Soak wooden skewers in water for 30 minutes to prevent burning.
- Instant-read thermometer: To check doneness without cutting into the scallops.
Serving Suggestions
Grilled scallops are versatile. Here are some ideas for serving them.
- Over pasta: Toss with linguine, olive oil, garlic, and cherry tomatoes.
- On a salad: Serve over mixed greens with a citrus vinaigrette.
- As tacos: Place in warm corn tortillas with slaw and avocado.
- With rice: Pair with cilantro lime rice and black beans.
- As an appetizer: Serve on a platter with dipping sauce like aioli or cocktail sauce.
Frequently Asked Questions
Can I Grill Frozen Scallops?
It is best to thaw scallops first. Frozen scallops release too much water and will steam instead of sear. Thaw them in the refrigerator overnight or in a bowl of cold water for 30 minutes. Pat them dry before grilling.
How Do I Know When Scallops Are Done?
Scallops are done when they are opaque in the center and firm to the touch. The internal temperature should be 115-120°F (46-49°C) for medium-rare. They will continue to cook after removal, so take them off slightly before they reach your desired doneness.
Why Are My Scallops Sticking To The Grill?
Sticking usually happens because the grill is not hot enough or the scallops are not dry enough. Make sure your grill is preheated to high heat and the grates are clean and oiled. Also, pat the scallops dry thoroughly before seasoning.
Can I Use Wooden Skewers For Scallops?
Yes, wooden skewers work well. Soak them in water for at least 30 minutes before grilling to prevent burning. Thread the scallops with a little space between each for even cooking.
What Is The Best Oil For Grilling Scallops?
Use an oil with a high smoke point, like avocado oil, grapeseed oil, or canola oil. Olive oil has a lower smoke point and can burn, giving the scallops a bitter taste. A light coating is all you need.
Final Tips For Success
Grilling scallops is easy once you know the basics. Remember these key points:
- Always use dry-packed sea scallops.
- Pat them very dry before seasoning.
- Preheat the grill to high heat and oil the grates.
- Cook for 2-3 minutes per side without moving them.
- Do not overcook—scallops are best when slightly translucent in the center.
With practice, you will be able to grill scallops confidently. They are a quick, impressive dish that works for any occasion. Try different seasonings and serving styles to find your favorite.
