Step-by-Step Instructions for Grilled Steak and Sweet Potato Skillet

1. Preheat your grill. If using a gas grill, preheat to medium-high heat (around 400-425°F). For a charcoal grill, arrange the coals for direct heat. You should be able to hold your hand about 6 inches above the grate for 3-4 seconds. This high heat is perfect for searing the steak.
2. Season the steak. In a bowl, toss the thinly sliced steak with 1 tablespoon of olive oil, chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, and pepper. Make sure every piece is evenly coated. Set aside.
3. Par-cook the sweet potatoes (optional but recommended). To ensure perfectly cooked sweet potatoes, par-cook them in the microwave for 3-4 minutes or boil them for 5 minutes until slightly tender. This step helps them cook through evenly on the grill.
4. Heat your skillet. Place a large cast-iron skillet on the grill grate. Add the remaining 1 tablespoon of olive oil and let it heat up for about a minute until it shimmers.
5. Cook the sweet potatoes. Add the diced sweet potatoes to the hot skillet in a single layer. Cook for 8-10 minutes, stirring occasionally, until they are golden brown and caramelized at the edges. The direct heat from the grill brings out their natural sweetness and adds a lovely smoky flavor.
6. Add the vegetables. Push the sweet potatoes to one side of the skillet. Add the sliced red onion and bell pepper to the other side. Cook for 4-5 minutes until they are soft and slightly charred. Add the minced garlic and cook for another minute until fragrant.
7. Cook the steak. Push the vegetables to the sides and add the seasoned steak to the center of the skillet in a single layer. Cook for 2-3 minutes per side, stirring occasionally, until browned and cooked to your desired doneness. The high heat creates a beautiful caramelized crust on the meat.
8. Combine and serve. Toss everything together and let it cook for 1-2 minutes to meld the flavors. Remove the skillet from the grill. Garnish with fresh parsley or cilantro and serve with lime wedges if desired. Enjoy this protein-packed grilled meal!

Tips for the Best High Protein Steak and Sweet Potato Skillet

• Slice the Steak Thinly: For the best texture, slice the steak against the grain into thin strips. This ensures tenderness and quick cooking. Freezing the steak for 15-20 minutes before slicing makes it easier to cut thin pieces.
• Don’t Overcrowd the Skillet: When cooking the steak, make sure it’s in a single layer. If your skillet is too full, the steak will steam instead of sear. Cook in batches if necessary.
• Get That Smoky Flavor: For an even more pronounced smoky taste, add a smoker box with wood chips (hickory or mesquite) to your gas grill. On a charcoal grill, the flavor is already built in. The smoked paprika also adds a lovely smoky undertone.
• Par-Cook for Perfect Sweet Potatoes: Par-cooking the sweet potatoes ensures they’re fully cooked through and creamy on the inside while getting caramelized and crispy on the outside. If you skip this step, make sure to dice them into small, uniform pieces.
• Heat Zone Management: On a charcoal grill, set up a two-zone fire. Start the skillet over direct heat for searing, then move to indirect heat if things are cooking too quickly. On a gas grill, simply adjust the burner knobs.

Delicious Variations to Try

• Spicy Version: Add a diced jalapeño with the vegetables and increase the chili powder. Stir in a dash of cayenne pepper for an extra fiery kick.
• BBQ Steak Version: Brush the steak with your favorite BBQ sauce during the last minute of cooking. The sweet and tangy flavor adds a wonderful BBQ recipe twist to this healthy dish.
• Garlic Herb Version: Add fresh rosemary or thyme to the skillet with the garlic. The aromatic herbs pair beautifully with the steak and sweet potatoes.
• Southwest Version: Add black beans and corn to the skillet along with the vegetables. Top with fresh cilantro, avocado, and a squeeze of lime for a zesty Tex-Mex twist.
• Breakfast Version: Top the finished skillet with fried or poached eggs for a high-protein breakfast or brunch that will keep you fueled all day.

Storage and Reheating Instructions

To Store: Allow the steak and sweet potato mixture to cool completely before transferring to an airtight container. It will stay fresh in the refrigerator for up to 4 days. This makes it perfect for meal prep!

To Reheat: For the best results, reheat in a non-stick skillet over medium heat on your grill or stovetop. Add a splash of broth or water to bring back moisture and prevent the steak from drying out. Stir occasionally until heated through. You can also reheat individual portions in the microwave, but cover the bowl to trap steam and add a little liquid.

Freezing: This dish freezes well for up to 3 months (without the vegetables, which can become mushy). Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions (FAQ)

Can I make this steak and sweet potato skillet on a gas grill?

Absolutely! A gas grill is ideal for this recipe. Its precise temperature control makes it easy to cook both the steak and sweet potatoes perfectly. Just preheat to medium-high and follow the instructions as written.

What type of steak is best for this dish?

Sirloin and flank steak are excellent choices because they’re lean, flavorful, and cook quickly when sliced thinly. Ribeye or strip steak also work wonderfully if you prefer more marbling. Just make sure to slice against the grain for maximum tenderness.

How do I get a smoky flavor without a charcoal grill?

While a charcoal grill naturally provides that wonderful smokiness, you can achieve a similar effect on a gas grill by using a smoker box filled with wood chips (hickory or mesquite work great). Alternatively, the smoked paprika in the seasoning already adds a nice smoky undertone.

Can I use regular potatoes instead of sweet potatoes?

Yes, regular potatoes work well too. Yukon Gold or Russet potatoes are great options. Just follow the same cooking instructions—they may need a slightly different cooking time depending on their size.

Can I use pre-cooked steak for this recipe?

You can use leftover grilled chicken or steak, but the flavor won’t be quite as rich. If using pre-cooked, simply slice it thinly and add it to the skillet during the last 2-3 minutes to heat through. For the best flavor, I recommend cooking fresh steak directly on the grill.

What can I serve with this skillet meal?

This dish is a complete meal on its own! However, if you want to round it out, serve it with a side salad, rice, or quinoa. It also pairs beautifully with a simple avocado or lime crema.
