How to Make the Best Steak and Pepper Foil Packets on the Grill: Customization is Key!
This Grilled Steak and Pepper Foil Packet Dinner is not only simple but also remarkably customizable, allowing you to tailor it to your taste and dietary needs. Here’s how you can make it truly your own:
- Choosing Your Steak: While this recipe calls for sirloin steak due to its excellent flavor, tenderness, and affordability, feel free to use your favorite cut. Ribeye, New York strip, or even flank steak (sliced against the grain for tenderness) work beautifully. Ensure the steak is cut into approximately 1 to 2-inch cubes for even cooking within the foil packet, ensuring every piece is perfectly cooked and juicy.
- Bell Pepper Variety: The recipe suggests three bell peppers, and any colors you like will work! Red bell peppers offer a sweeter flavor and beautiful color, as seen in the photos, but orange, yellow, and even green bell peppers (which have a slightly more robust, less sweet flavor) can be used. Don’t hesitate to mix and match for a vibrant and flavorful medley. You could also experiment with other firm vegetables like zucchini, cherry tomatoes, or sliced mushrooms.
- Onion Selection: Sweet yellow onions are preferred for their mellow flavor, which caramelizes beautifully on the grill. However, white onions provide a sharper bite, and red onions add a distinct color and slightly peppery taste. Choose based on your preference or what you have on hand; all will contribute wonderfully to the overall flavor profile of these grilled steak foil packets.
- Potato Power (or Low-Carb Options): Dicing red potatoes into small, uniform pieces is crucial for even cooking, ensuring they become tender at the same rate as the steak and peppers. If you’re aiming for a lower-carb meal, feel free to omit the potatoes entirely or substitute them with other vegetables like cauliflower florets or green beans. Sweet potatoes are also a fantastic alternative for a different flavor dimension.
To prevent any sticking and to ensure all your ingredients cook beautifully, you’ll want to generously spray the inside of your heavy-duty aluminum foil with nonstick cooking spray. Additionally, tossing the cubed steak and diced vegetables with a good quality olive oil (or avocado oil for a higher smoke point) before assembling the packets helps to coat everything, promoting browning and preventing anything from burning directly over the grill flames. This simple step ensures a perfectly cooked and flavorful meal every time.

Before grilling, I love to toss the steak and veggies with a blend of dried pantry spices to enhance their natural flavors. A classic combination of paprika, garlic powder, salt, and black pepper works wonders, but feel free to experiment with your favorite steak rubs or spice blends. Once these delicious Steak and Pepper Foil Packets are cooked and removed from the grill, a fresh garnish can elevate the dish even further. We enjoy a sprinkle of fresh chopped parsley for a bright, herbaceous note and a touch of crushed red pepper flakes for a gentle kick. This final touch is completely optional, so customize it to your liking – you do YOU!
Expert Tips for Folding Foil Packets for the Grill
Properly sealing your foil packets is essential for trapping steam and flavor, ensuring your ingredients cook perfectly and don’t dry out. You’ll need heavy-duty aluminum foil to withstand the heat of the grill and non-stick cooking spray for easy release. Follow these steps for perfectly sealed packets:
- Prepare Your Foil: Tear off a sheet of heavy-duty aluminum foil approximately 12-18 inches long. The exact length depends on how much food you’re putting in each packet; aim for enough to easily fold and seal. Generously spray the dull side of the foil with nonstick cooking spray. For this recipe, you will typically prepare four (4) such sheets.
- Combine Ingredients: Once all your steak and veggies are prepped and seasoned, toss them together thoroughly in a large bowl with olive oil and your chosen spices. This ensures every piece is coated and flavorful.
- Divide and Distribute: Evenly divide the seasoned mixture among your prepared sheets of foil. Try to keep the ingredients in the center of the foil, leaving ample space around the edges for folding.
- The First Fold (Long Edges): To close each packet, bring the two long edges of the foil together directly above the food. Crimp them together tightly, folding the seam over at least twice, about 1/2 inch each time, to create a secure seal. Make sure there’s a little air space between the food and the foil; this helps steam build up inside, which is crucial for cooking the ingredients evenly.
- The Side Folds (Short Edges): Next, fold up the short ends of the foil. Press the edges together and fold them over once or twice, creating another 1/2-inch space. The goal is to create a tight, sealed pouch that allows steam to circulate and cook the food without any leaks.
- Grill and Enjoy: With your packets securely sealed, they are now ready for the grill! Place them directly on the grates and let the magic happen. The result will be a tender, flavorful, and incredibly satisfying meal.


These Steak and Potato Foil Packets are absolutely perfect for weekend entertaining, especially since they can be prepped ahead of time and cooked in less than 30 minutes. Imagine having friends or family over; you can easily toss these on the grill, mix up a refreshing cocktail while they cook, and then everyone can dig into their personalized, flavorful meal. It’s a relaxed approach to hosting that everyone will appreciate.
Beyond special occasions, these versatile foil packets are also fantastic for weekly meal prep. During busy seasons, grilling a variety of proteins and then assembling complete meals like these foil packets makes weeknight dinners incredibly straightforward. They are a complete, balanced meal all in one, which undeniably makes Monday dinners (and any other busy night) a little bit easier and a lot more delicious, wouldn’t you agree? This recipe is also simple to double or triple for larger families or to ensure you have plenty of scrumptious leftovers. Enjoy the convenience and flavor!

- 4 cloves garlic, minced
- 1/2 tablespoon paprika
- 1 teaspoon Kosher salt
- 1 teaspoon black pepper
- ¼ cup olive oil

- 1-2 teaspoons crushed red pepper flakes, for garnish – optional, for a little heat
Instructions
-
Preheat your grill to medium-high heat, aiming for approximately 400°F (200°C). While the grill is heating, begin preparing your foil packets. Take four sheets of heavy-duty aluminum foil, each roughly 12-18 inches long, and spray the inside with nonstick cooking spray.
-
Using a chef’s knife, quarter the potatoes into small, even pieces. Dice the yellow onion, and thinly slice the bell peppers. Cut the sirloin steak into approximate 1.5-inch to 2-inch chunks. In a large mixing bowl, combine the cubed steak and all the chopped vegetables. Add the olive oil, minced garlic, paprika, Kosher salt, and black pepper. Toss everything together thoroughly until all ingredients are well coated with the seasoning blend.
-
Divide the seasoned steak and veggie mixture evenly among the four prepared sheets of foil. Carefully gather the long edges of each foil sheet and crimp them together tightly. Then, fold up the shorter ends to create securely sealed packets, ensuring there’s a little space inside for steam to circulate.
-
Place the sealed foil packets directly on the preheated grill grates. Grill for 25-30 minutes, or until the steak is cooked to your desired doneness and the vegetables are tender. Carefully remove the packets from the grill. Open them with caution to release the steam. If desired, garnish with fresh chopped parsley and a sprinkle of crushed red pepper flakes. Serve immediately and savor this effortless and flavorful grilled dinner!
