Ingredients (Serves 4–6)

Built directly from your post, with a few helpful “optional but awesome” add‑ins for finish and balance. We also include weights for accuracy.

Core Ingredients

• Lean sirloin steak, cut into 2‑inch chunks — 2 lbs (900 g)
• Baby yellow potatoes, quartered — 1 lb (450 g)
• Minced garlic — 1 Tbsp (about 3 cloves / 12 g)
• Italian seasoning — 2 tsp
• Onion powder — 1 tsp
• Olive oil — 3 Tbsp (45 ml)
• Kosher salt — 1–1½ tsp, to taste
• Freshly ground black pepper — ¾ tsp

Optional Flavor Boosters (Highly Recommended)

• Unsalted butter, diced — 2 Tbsp (28 g) for a glossy finish

• Red pepper flakes — a pinch for gentle heat
• Smoked paprika — ½ tsp for light smokiness if cooking indoors

Before You Start: Prep & Packet Fundamentals

Cut Size Matters

Keep steak chunks at ~2 inches and potato pieces at ¾–1 inch. This size sync keeps steak juicy while potatoes soften in similar time. If your potatoes are larger, halve or pre‑microwave them 3–4 minutes (tossing halfway) to jump‑start tenderness.

Foil Strategy

• Use heavy‑duty aluminum foil (or double up regular foil) to prevent tears.
• Make packets roughly 12×16 inches, pile ingredients in the center, then fold long sides together and crimp; roll/press ends to fully seal, leaving a little headspace for steam.
• For grill use, place packets seam‑side up to keep juices corralled.

Seasoning & Oil

Salt draws moisture—great for flavor, but we want a balance. Toss steak and potatoes with oil and spices first, taste a potato piece, then salt to preference. This sequence helps avoid oversalting, especially if you’ll finish with butter or a salty garnish like Parmesan.

Step‑by‑Step Cooking Methods

Universal Toss

1. In a large bowl, combine steak, potatoes, olive oil, garlic, Italian seasoning, onion powder, pepper, and optional smoked paprika/red pepper flakes. Toss to coat evenly.
2. Season with 1–1½ tsp kosher salt to taste. Toss again. If finishing with butter, you can under‑salt slightly now and adjust later.
3. Divide mixture into 4–6 mounds on prepared foil sheets. Dot each with a few small cubes of butter (optional) and sprinkle with a little parsley (save most for garnish).
4. Seal packets tightly, creating a little internal air space for steam.

Oven Method (Weeknight Reliable)

1. Preheat to 425°F / 220°C. Place packets on a rimmed sheet pan for easy handling.
2. Bake 18–22 minutes for medium‑rare to medium steak and tender potatoes. If potatoes are larger than 1 inch, add 3–5 minutes or pre‑microwave as noted above.
3. Rest packets 3 minutes before opening (steam is hot!). Garnish with parsley and a lemon squeeze.

Grill Method (Smoky & Summery)

1. Preheat grill to medium‑high (425–450°F / 218–232°C). Oil grates lightly.
2. Grill packets seam‑side up over direct heat 10–12 minutes, then rotate 180° and grill another 6–8 minutes. For thicker potatoes, move to indirect heat and cook 4–6 minutes more.
3. Rest 3 minutes. Carefully open (away from you), garnish, and serve.

Air Fryer Method (Small Batch, Crisp Edges)

1. Heat air fryer to 400°F / 205°C. Build smaller packets to fit your basket.
2. Air fry 12–16 minutes, flipping once at the 8‑minute mark. Check potatoes for tenderness; add 2–3 minutes if needed.
3. Open, garnish, and serve hot. For extra browning, finish open‑packet 2 minutes.

Doneness Guide & Texture Guardrails

• Medium‑rare steak bites: Pull around 125–130°F / 52–54°C internal; carryover heat inside the packet raises temp a touch during the 3‑minute rest.
• Medium: Aim for 135°F / 57°C before resting.
• Potatoes: Tender when easily pierced with a fork; if not, reseal and cook 3–5 minutes more.
• Juiciness insurance: Keep chunks chunky, don’t overcook, and add a pat of butter or a drizzle of olive oil when serving.

Chef‑Level Tips from the Pros 👨‍🍳👩‍🍳

Gordon Ramsay–Style Heat Discipline

• Big pieces = big payoff: Two‑inch steak cubes retain moisture better than small dice.
• Season in layers: Spice/oil first, then salt, then finish with acid (lemon) and herbs to brighten.

Ina Garten’s Make‑Ahead Ease

• Pre‑packet up to 24 hours: Toss everything except salt and lemon. Refrigerate. Salt just before sealing and cooking.
• Entertaining move: Write guests’ names on packets for easy hand‑off and customized doneness. ✍️

Bobby Flay’s Flame & Finish

• Crust without the mess: After packet cooking, quickly sear steak bites 30–45 seconds in a ripping‑hot skillet with a dab of butter and garlic to add caramelized edges (optional, but wow).
• Smoked paprika + charred lemon: Halve lemons, char cut‑side on the grill, and squeeze over packets.

Ree Drummond’s Family‑Friendly Swaps

• Veggie boosters: Toss in green beans or bell peppers (½‑inch strips) for color and crunch.
• Kid‑pleasing finish: Sprinkle a little shredded cheddar over open packets; close 1 minute to melt.

Note: Tips above are chef‑inspired best practices for home cooks—not direct quotations.

Add‑Ins & Flavor Variations

• 🌶️ Cajun Garlic: Swap Italian seasoning for 2 tsp Cajun seasoning; add a pinch of cayenne.
• 🌿 Rosemary & Thyme: Add 1 tsp chopped fresh rosemary + ½ tsp thyme for a steakhouse vibe.
• 🧈 Garlic‑Herb Butter Finish: Mash 2 Tbsp softened butter with 1 minced garlic clove + parsley; swirl into hot packets at the table.
• 🥓 Steakhouse Bacon: Scatter 2–3 Tbsp crisped bacon bits before sealing for smoky pops.
• 🧀 Parmesan Pepper: Open packets and shower with 2–3 Tbsp finely grated Parm and extra black pepper.

Health Tips & Food Safety 🛡️

• Cross‑contamination: Keep raw steak and ready‑to‑eat garnishes separate; wash boards/knives in hot, soapy water.
• Chill smart: Refrigerate steak until prep; don’t let it sit at room temp longer than 30 minutes.
• Cook temps: Beef is safe to eat at various doneness levels; use a thermometer to avoid overshooting your target.
• Leftovers: Chill within 2 hours; reheat to 165°F / 74°C. Enjoy within 3–4 days.
• Lighter swaps: Use 1 Tbsp oil + 1 Tbsp water or stock, and skip butter. Serve with a big salad for fiber and balance.

Troubleshooting: Exactly How to Nail It

Potatoes Still Firm?

• Pre‑microwave potato quarters 3–4 minutes or cut a little smaller next time.
• Return sealed packets to heat for 3–5 more minutes; avoid opening repeatedly (you’ll vent steam).

Steak Overcooked?

• Shorten cook time by 2–3 minutes and rest longer; carryover heat inside packets is powerful.
• Keep pieces at ~2 inches; smaller pieces cook too fast.

Not Enough Flavor?

• Finish with salt, a squeeze of lemon, and fresh herbs—acidity and freshness wake up richness.
• Add a dab of compound butter or a sprinkle of Parmesan to boost umami.

Make‑Ahead, Storage & Reheating

• Make‑ahead (24 hours): Toss everything but salt and lemon; refrigerate in a covered bowl. Salt just before sealing/cooking.
• Fridge: 3–4 days in airtight containers. Keep juices—they’re flavor!
• Reheat: Low and slow on the stovetop with a splash of water/stock, or covered in a 300°F / 150°C oven until hot. Microwave in short bursts, stirring once.
• Freeze: Best with potatoes slightly underdone; freeze up to 2 months. Thaw overnight and reheat gently.

10 Frequently Asked Questions (FAQs)

1) Can I use a different cut of beef?

Yes. Top sirloin is ideal, but ribeye (richer) or New York strip (tender) also work. Chuck needs longer time and can become stewy in packets, so keep to quick‑cooking cuts.

2) How do I ensure potatoes cook through?

Cut to ¾–1 inch, keep packets sealed, and avoid peeking. For larger potatoes, pre‑microwave or parboil briefly. Yukon Golds and baby yellows cook faster than russets.

3) Can I add vegetables?

Absolutely. Bell peppers, green beans, asparagus tips, or red onion wedges are great. Add denser veg (carrots) only if cut small or par‑cooked.

4) What if I don’t have heavy‑duty foil?

Double up regular foil to prevent leaks. You can also place packets on a baking sheet or grill pan to catch any juices.

5) Can I meal‑prep these?

Yes. Build packets up to 24 hours ahead (hold the salt and lemon), refrigerate, then salt and cook day‑of. Leftovers reheat well with a splash of stock.

6) How do I keep steak juicy?

Keep pieces large, don’t overcook, and rest packets 3 minutes before opening. Finishing with a pat of butter or a drizzle of olive oil helps retain moisture and flavor.

7) Can I make it dairy‑free?

Yes. Skip butter and finish with extra‑virgin olive oil and lemon. The recipe is naturally dairy‑free without the butter option.

8) Are foil packets safe?

Yes. Use food‑safe aluminum foil and avoid direct contact with highly acidic marinades for prolonged storage. For grills, keep flare‑ups under control and avoid puncturing packets.

9) How do I scale for a crowd?

Double or triple the ingredients and make more, smaller packets (they cook more evenly). Stagger packets on the grill or use two oven racks and rotate halfway.

10) What can I serve alongside?

Keep it bright and fresh: lemony arugula salad, grilled asparagus, or a tomato‑cucumber salad. Bread or rice pilaf is great for catching juices.
