Marinated Steak and Potato Skewers Ingredients
For the Marinade
• Lean beef (sirloin recommended) – Perfect for tenderness and flavor, but any lean cut works.
• Soy sauce – Adds umami depth; low-sodium is a great healthy alternative.
• Neutral oil (grapeseed, canola, or vegetable) – Prevents sticking and ensures even cooking.
• Worcestershire sauce – Infuses richness; tamari can be used for gluten-free options.
• Packed brown sugar – Balances flavors with sweetness; you can substitute with white sugar if necessary.
• Small diced yellow onion – Enhances the marinade with aromatic flavor; shallots are a lovely swap.
• Garlic cloves (minced) – Fresh garlic is key for a robust taste; garlic powder will work in a pinch.
• Kosher salt – Boosts overall flavor; sea salt is a good alternative.
• Black pepper – Adds spice; use white pepper for a milder flavor.
• Crushed red pepper flakes – Brings heat and complexity; fresh chilies add even more zest.
For the Skewers
• Small red new potatoes – A delightful side that complements the beef; baby potatoes are an excellent alternative.
• Unsalted butter (softened) – For basting, it gives a rich flavor to the potatoes; margarine can substitute but changes the taste.
• Minced Italian parsley – Freshens up the basting butter and adds a pop of color; cilantro or chives can also work.
These mouthwatering Marinated Steak and Potato Skewers not only promise flavor but also bring the essence of summertime grilling to your table. Enjoy!
Step‑by‑Step Instructions for Marinated Steak and Potato Skewers
Step 1: Marinate the Beef
In a bowl or zip-top bag, combine the sirloin steak with soy sauce, Worcestershire sauce, brown sugar, diced onion, minced garlic, kosher salt, black pepper, and crushed red pepper flakes. Ensure all the meat is well coated in the marinade. Seal the bag or cover the bowl and refrigerate for at least 6 hours or overnight for maximum flavor infusion.
Step 2: Prepare the Potatoes
While the beef marinates, bring a pot of cold salted water to a boil. Add the small red new potatoes and let them cook for about 7 minutes, or until they are just tender but still firm enough to hold their shape. Drain the potatoes and allow them to cool slightly before assembling the skewers.
Step 3: Make the Basting Butter
In a mixing bowl, combine the softened unsalted butter with minced Italian parsley, a pinch of black pepper, and a sprinkle of kosher salt. Mix well until all ingredients are thoroughly incorporated. Set this basting butter aside at room temperature—don’t refrigerate it, as it should be soft for easy application later.
Step 4: Assemble the Skewers
Preheat your grill to medium heat, around 350°F (175°C). Take skewers (metal is preferred) and start threading the marinated steak pieces and partially cooked potatoes onto the skewers in an alternating fashion. Fill each skewer, leaving a little space between the pieces for even cooking.
Step 5: Grill the Skewers
Once the grill is ready, place the assembled skewers on the grates. Grill the Marinated Steak and Potato Skewers for about 10 minutes, turning occasionally to achieve even cooking. Baste with the prepared parsley butter during grilling for added flavor. Look for a nice sear on the meat, indicating it’s reached a medium doneness.
Step 6: Serve
Once cooked to your liking, remove the skewers from the grill and let them rest briefly. Serve the Marinated Steak and Potato Skewers hot, accompanied by any remaining parsley butter for dipping. Enjoy the delightful flavors of this summer grilling staple!

How to Store and Freeze Marinated Steak and Potato Skewers
Fridge: Store any leftovers in an airtight container for up to 3 days. Make sure to let the skewers cool completely before sealing to prevent condensation.
Freezer: If you want to freeze the skewers, place them in a freezer-safe bag or container. They can be kept for up to 3 months—perfect for last-minute meals!
Reheating: To reheat, thaw in the fridge overnight and then grill on medium heat for about 5-7 minutes until heated through, basting with a little butter for extra flavor.
Make-Ahead: Prepare and marinate the skewers a day in advance. Grill them fresh when ready to serve for the best flavors in your Marinated Steak and Potato Skewers!
Expert Tips for Marinated Steak and Potato Skewers
-
Choose Quality Meat: Select high-quality sirloin for tenderness and flavor. Lower-grade cuts can become tough if overcooked.
-
Don’t Rush Marination: Allow the meat to marinate for at least 6 hours, or overnight if possible. This optimizes the flavor infusion and ensures juicy, tender steak.
-
Par-Cook Potatoes: Boil the potatoes until just tender. This prevents them from overcooking on the grill, which can lead to a mushy texture.
-
Maintain Grill Temperature: Keep the grill at medium heat. A temperature that’s too high can char the outside while leaving the inside undercooked.
-
Baste Frequently: Brush the skewers with the basting butter often during grilling for added flavor and moisture. This enhances the rich taste of your marinated steak and potato skewers.
-
Rest Before Serving: Let the skewers rest for a few minutes after grilling. This allows the juices to redistribute, resulting in a more flavorful bite.
Make Ahead Options
These Marinated Steak and Potato Skewers are perfect for meal prep enthusiasts! You can prepare the marinade and marinate the beef up to 24 hours in advance, allowing the flavors to fully develop. Simply combine the beef with marinade ingredients and refrigerate it in a zip-top bag or covered bowl. Additionally, you can par-cook the potatoes up to 3 days ahead; just boil them until slightly tender, cool, and store them in the fridge. To maintain quality, ensure you keep the beef and potatoes covered tightly to prevent drying out. When you’re ready to grill, assemble the skewers with the marinated beef and potatoes, baste with the prepared parsley butter, and grill for about 10 minutes for a delicious weeknight meal with minimal effort!

Marinated Steak and Potato Skewers Recipe FAQs
How do I choose the right beef for these skewers?
Absolutely! When selecting your beef for Marinated Steak and Potato Skewers, I recommend going for a lean cut like sirloin. Sirloin not only enhances the flavor but also ensures tenderness when grilled. Look for well-marbled meat, which indicates a juicy piece. If you’re in a pinch, flank steak or tenderloin can be good alternatives too.
How do I store the leftover skewers?
Very easy! After enjoying your skewers, make sure to let them cool completely, then store any leftovers in an airtight container in the refrigerator for up to 3 days. This way, they’ll stay fresh and ready for a quick meal. If you want to keep them longer, consider freezing them!
Can I freeze the marinated beef and potatoes before grilling?
Absolutely! To freeze, place the marinated beef and any leftover assembled skewers into a freezer-safe bag or container. They will keep well for up to 3 months. When you’re ready to enjoy them, thaw in the refrigerator overnight, and they’ll be ready for grilling!
What should I do if my beef becomes tough after grilling?
Don’t worry, it happens to the best of us! If your beef turns out tough, it’s often due to overcooking. Always aim for medium doneness and use a meat thermometer to check the internal temperature (about 145°F or 63°C) for juicy results. Also, marinating the meat for a longer time can help it stay tender.
Are there any allergies I should consider with this recipe?
Great question! This recipe contains soy sauce, which is a common allergen, particularly for those with gluten sensitivities (unless you use gluten-free tamari). Additionally, check for any allergies to garlic or onion, as these ingredients are freestanding flavors in the marinade. Always tailor the ingredients to fit the needs of your guests!
Can I use vegetables on the skewers as well?
Absolutely! Feel free to enhance your Marinated Steak and Potato Skewers by adding seasonal vegetables. Bell peppers, zucchini, cherry tomatoes, or even mushrooms add color and flavor, turning your skewers into a fantastic medley. Just be sure to cut the veggies into similar sizes for even cooking!
