These grilled surf and turf skewers combine tender sirloin and succulent shrimp for a high-protein meal. They are quick to prepare and perfect for an elegant outdoor dinner using a standard grill.

List of ingredients

1 lb sirloin steak – cut into uniform bite-sized cubes.
1/4 cup olive oil – divided for use in both marinades.
1/4 cup low sodium soy sauce – provides a savory base for the beef.
2 cloves of garlic, minced – used to flavor the steak marinade.
Salt and pepper – used for seasoning both proteins.
24 med-large raw peeled shrimp with tails on – ensures a professional look.
1/4 cup olive oil – for the shrimp marinade.
1/4 cup lemon juice – adds essential acidity to the seafood.
2 cloves of garlic, minced – used to flavor the shrimp marinade.

step-by-step instructions

Prepare skewers: Soak wooden skewers in water for at least 1 hour to prevent them from burning, or use reusable metal skewers.
Defrost: Ensure shrimp are completely thawed if they were previously frozen.
Prep garlic: Mince all garlic cloves finely to ensure even distribution in the marinades.
Cube steak: Cut the sirloin steak into consistent bite-sized cubes.
Separate proteins: Place the shrimp in one mixing bowl and the cubed steak in a second bowl.
Marinate shrimp: Toss the shrimp in olive oil, lemon juice, and minced garlic.
Marinate steak: Toss the steak cubes in olive oil, low sodium soy sauce, and minced garlic.
Chill: Cover both bowls and refrigerate for approximately one hour to infuse the flavors.
Assemble: Thread the shrimp and steak onto separate skewers to allow for different cooking times.
Heat grill: Preheat your grill to medium-high heat.
Start grilling: Place the skewers on the hot grill grates.
Cook shrimp: Grill the shrimp for 3 minutes per side, then remove them immediately.
Cook steak: Grill the steak for 12 minutes total, rotating every 3 minutes while keeping the grill lid closed.
Rest: Allow the steak skewers to rest for 10 minutes before serving to keep the meat juicy.

Optimizing Protein Selection

Choosing the Right Sirloin Cut

Select a top sirloin or sirloin tip for the best balance of flavor and tenderness. Trim away any thick layers of silver skin or excess gristle before cubing. This ensures every bite is tender and consistent.

Selecting High-Quality Shrimp

Use medium-to-large shrimp to ensure they do not overcook before the steak is done. Look for shrimp that are firm to the touch and have a mild, briny scent. Leaving the tails on helps protect the meat and provides a handle for eating.

Maintaining Uniform Cube Size

Cut the steak into cubes approximately one inch in size. Uniformity is critical because smaller pieces will overcook while larger pieces remain raw in the center. Use a sharp chef’s knife for clean cuts.

Handling Frozen Seafood

Thaw shrimp slowly in the refrigerator overnight for the best texture. Avoid using hot water to defrost, as this can make the shrimp rubbery. Pat the shrimp dry with paper towels before adding the marinade to prevent dilution.

Advanced Grilling Techniques

Managing Medium-High Heat

Aim for a grill temperature between 400°F and 450°F for a proper sear. You can test the heat by holding your hand four inches above the grate; it should feel uncomfortable after two seconds. Consistent heat prevents the meat from steaming rather than searing.

Using the Grill Lid for Convection

Keep the grill lid closed while cooking the steak to trap heat and cook the interior. This creates a convection effect that mimics an oven, ensuring the beef reaches the desired temperature. Only open the lid briefly to rotate the skewers.

Identifying Done Shrimp

Shrimp are finished when they turn opaque and form a tight ‘C’ shape. If they curl into a tight ‘O’ shape, they are likely overcooked and will be rubbery. Remove them from the heat the moment the translucency disappears.

Achieving a Deep Sear on Beef

Avoid moving the steak too frequently during the first three minutes of grilling. This allows the Maillard reaction to occur, creating a brown, flavorful crust. Rotate every three minutes to ensure all sides are evenly browned.

Marinade Customization and Science

Replacing Soy Sauce with Coconut Aminos

For a soy-free alternative, use coconut aminos in the same quantity as the soy sauce. Coconut aminos have a slightly sweeter profile and lower sodium content. This change maintains the savory depth while catering to different dietary needs.

Enhancing Garlic Infusion

Use a garlic press or microplane to create a paste rather than rough chops. A finer mince allows the garlic oils to integrate more thoroughly with the olive oil. This results in a more consistent flavor across all pieces of meat.

Citrus Alternatives for Seafood

While lemon juice is traditional, lime juice provides a zesty, tropical twist to the shrimp. Orange juice can also be used for a sweeter, milder acidity. Ensure the acid ratio remains the same to avoid ‘cooking’ the shrimp in the marinade.

The Role of Olive Oil

Olive oil acts as a vehicle for the garlic and soy flavors to penetrate the protein. It also creates a barrier that prevents the meat from sticking to the grill grates. For a higher smoke point, you may substitute with avocado oil.

Complementary Side Dishes

Pairing with Fresh Summer Salads

Serve these skewers over a bed of mixed greens with a light vinaigrette. Ingredients like sliced strawberries, cucumber, and feta cheese complement the richness of the beef. The acidity of the salad cuts through the savory marinades.

Incorporating Starch-Based Sides

Grilled corn on the cob or roasted baby potatoes provide a hearty accompaniment. For a more refined option, try a side of creamy corn pasta or quinoa. These starches help balance the high protein content of the meal.

Creating a Signature Dipping Sauce

A garlic butter sauce or a fresh chimichurri adds an extra layer of flavor. Whisk together melted butter, minced parsley, and a squeeze of lemon for a simple dip. This enhances the natural flavors of both the beef and the shrimp.

Storage and Preservation

Refrigerating Leftovers

Store leftover skewers in an airtight glass container in the refrigerator. Ensure the meat has cooled slightly before sealing the lid to prevent excess condensation. These will remain fresh and safe to eat for up to four days.

Best Practices for Reheating

Avoid the microwave as it often makes shrimp rubbery and steak tough. Instead, reheat the skewers in a skillet over medium heat with a teaspoon of oil. Warm them gently until just heated through to preserve the texture.

Freezing Cooked Proteins

Cooked steak and shrimp can be frozen for up to two months if vacuum-sealed. Remove the proteins from the skewers before freezing to save space and prevent ice crystals. Thaw in the fridge before reheating in a pan.

Troubleshooting Common Issues

Preventing Meat from Sticking

Ensure your grill grates are scrubbed clean and lightly oiled before adding the skewers. Do not try to flip the meat too early; it will naturally release from the grate once a proper sear has formed. Use metal tongs for a firm grip.

Fixing Overcooked Shrimp

If the shrimp cook too quickly, move them to a cooler part of the grill. If they are already overcooked, serve them with a creamy sauce or a squeeze of fresh lemon to add moisture. In the future, thread shrimp on their own separate skewers.

Managing Grill Flare-ups

Flare-ups occur when oil from the marinade drips onto the coals or burners. Move the skewers to a different section of the grill immediately to avoid charring. Keep a spray bottle of water nearby to douse small flames safely.

Frequently Asked Questions

Can I use a different cut of beef?

Yes, you can use ribeye or filet mignon for a more luxurious experience. Ribeye offers more fat and flavor, while filet is leaner and more tender. Adjust the cooking time slightly based on the fat content of the cut.

How long can I marinate the shrimp?

Shrimp should not marinate for more than two hours. Because they are delicate, the acid in the lemon juice will begin to break down the proteins, making them mushy. One hour is the ideal window for maximum flavor.

Can I cook these in an oven?

You can broil the skewers on a parchment-lined baking sheet for a similar effect. Set the oven to high broil and flip the skewers every few minutes. However, you will miss the smoky flavor that only a grill provides.

Why should I skewer the proteins separately?

Shrimp cook much faster than steak and would be overdone by the time the beef is ready. Using separate skewers allows you to remove the seafood while the steak continues to grill. This ensures both proteins are cooked to their ideal doneness.
