Steak and Potato Foil Packets in the Oven (with Broccoli!)

---

As a busy mom juggling a 9-to-5, a baby, video games (yes, I’m a gamer!), and trying to fit in some semblance of self-care, I need dinners that don’t require a lot of hands-on time. That’s where these oven-baked steak foil packets come in clutch.

Here’s why they’re my go-to:

1. Minimal Cleanup – Everything cooks in foil, so there’s literally nothing to scrub. Just toss the foil when you’re done!

2. Hands-Off Cooking – Once you seal the packets and pop them in the oven, you’re done. No stirring, no flipping, no monitoring. The oven does everything.

3. Complete Meal in One – You’ve got protein (steak), carbs (potatoes), and veggies (broccoli, mushrooms, onions) all in one packet. No side dishes needed!

4. Customizable – Everyone can get their own packet customized to their preferences. My husband gets extra mushrooms, I skip them, the kids get less broccoli (we’re working on it!).

5. No Grill Needed – I love grilling, but when it’s freezing outside or raining, the oven is the perfect backup. You still get that tender, juicy steak without standing outside in the cold.

What’s in These Steak Foil Packets?

This recipe is all about simple, hearty ingredients that come together for a satisfying meal:

Protein:

• Top sirloin steak (about 1 lb) – cut into strips for quicker, more even cooking

Vegetables:

• Fingerling potatoes – these roast perfectly in 30 minutes
• Broccoli florets – fresh is best, but frozen works in a pinch
• Mushrooms – adds earthiness and meaty texture
• Yellow onion – sweetens as it cooks and adds flavor

Seasonings & Butter:

• Olive oil – helps everything cook and prevents sticking
• Garlic herb butter – the finishing touch that makes everything irresistible
• Fresh rosemary – aromatic and pairs perfectly with steak
• Dried thyme – classic herb for beef

The secret ingredient: That garlic herb butter at the end! It melts over everything and ties all the flavors together.

How to Make Steak Foil Packets in the Oven (Step-by-Step)

Making these is incredibly simple – even if you’ve never made foil packets before, you’ll nail it on the first try.

Step 1: Prep Your Ingredients (10 minutes)

Potatoes: Keep fingerling potatoes whole if they’re small (1-2 inches), or halve them if larger. They should be roughly uniform size so they cook evenly.

Broccoli: Cut into medium florets (about 1-2 inch pieces). Too small and they’ll overcook; too large and they won’t cook through.

Steak: Slice into 1-inch wide strips. Strips cook faster and more evenly than big chunks, and they’re easier to eat!

Onion: Cut into large chunks (about 1-inch pieces)

Mushrooms: Slice if large, leave whole if small

Step 2: Create Your Foil Packet Base

This is the key to leak-proof packets! Here’s my method:

1. Use TWO sheets of heavy-duty aluminum foil per packet (about 18 inches long each)
2. Cross them in a “T” shape – one vertical, one horizontal
3. Spray the center with nonstick spray (prevents sticking!)

This double-layer method ensures steam stays inside and nothing leaks. Trust me, I learned this the hard way after a packet leaked all over my oven!

Step 3: Layer Your Ingredients

Order matters here! Layer like this for best results:

1. Bottom layer: Potatoes and onions (they take longest to cook)
2. Middle layer: Broccoli and mushrooms
3. Top layer: Steak strips

Why this order? Potatoes need the most heat, and they’re closest to the hot foil. Steak is on top so it doesn’t overcook.

Step 4: Season and Drizzle

• Drizzle 2 tablespoons olive oil over everything
• Season generously with salt and pepper (don’t be shy!)
• You can add garlic powder, onion powder, or your favorite steak seasoning here too

Step 5: Seal the Packets

Here’s how to create a tight seal:

1. Bring opposite sides of foil together and fold down 2-3 times
2. Fold in the ends tightly, creating a sealed pouch
3. Make sure there are no gaps – steam needs to stay inside!

The packet should look like a little pillow when you’re done.

Step 6: Bake at 400°F for 30 Minutes

• Place packets on a baking sheet (for stability and to catch any drips)
• Bake for 30 minutes without opening
• Don’t peek! Opening the packet lets steam escape

Step 7: Add Garlic Herb Butter & Rest

While the packets are baking, make your garlic herb butter:

• Mix softened butter with minced garlic, fresh rosemary, thyme, and garlic salt
• When packets come out of the oven, carefully open (watch for steam!)
• Add a heaping spoonful of garlic butter to each packet
• Reseal and let rest for 5-10 minutes

This resting time is crucial! The butter melts and coats everything, the steak reabsorbs juices, and the flavors meld together.

How to Know When Steak Foil Packets Are Done

Since everything’s wrapped up, it can be tricky to know when it’s ready. Here are the indicators:

Visual Check (after 30 minutes):

• Carefully open one packet (watch for hot steam!)
• Steak should be browned on the outside
• Potatoes should look tender and slightly golden

Fork Test:

• Poke a potato with a fork – it should slide in easily with no resistance
• This is your best indicator that everything’s cooked through!

Temperature Check:

• Steak should reach 145°F for medium (use an instant-read thermometer)
• For medium-well, go to 150-155°F
• For well-done, 160°F+

Pro tip: If the steak is done but potatoes aren’t tender yet, remove the steak, reseal just the veggies, and give them another 5-10 minutes.

Oven vs. Grill: Which is Better for Steak Foil Packets?

I get asked this constantly! Both methods work, but here’s the breakdown:

Oven Method (What This Recipe Uses)

Pros:

• Consistent, even temperature – no hot spots
• Weather-proof (works year-round!)
• Hands-off – set it and forget it
• Can make multiple packets at once
• Better for meal prep

Cons:

• No smoky flavor
• Takes up oven space

Best for: Busy weeknights, cold weather, beginners, meal prep

Grill Method

Pros:

• Adds smoky flavor
• Frees up your kitchen
• Perfect for summer entertaining

Cons:

• Harder to regulate temperature
• Requires more attention (flipping, rotating)
• Weather-dependent
• Can create hot spots that burn food

Best for: Summer cookouts, when you want that grilled flavor

How to adapt this recipe for the grill

• Preheat grill to medium heat (about 400°F)
• Assemble packets the same way
• Place on indirect heat (not directly over flames)
• Cook for 25-30 minutes, rotating once halfway through
• Check for doneness and add 5 more minutes if needed

What to Serve with Steak Foil Packets

These are already a complete meal, but if you want to round things out:

Light Additions:

• Simple green salad with vinaigrette
• Crusty bread for soaking up that garlic butter
• Fresh fruit on the side

Make it a Feast:

• Garlic bread (extra butter never hurts!)
• Caesar salad
• Roasted corn on the cob

Drinks:

• Red wine (Cabernet or Malbec pairs beautifully with steak)
• Iced tea
• Lemonade

Honestly though? The foil packets are filling enough that we usually just add a simple salad and call it dinner.

How to Customize Your Steak Foil Packets

This is where you can get creative! Here are my favorite variations:

Different Proteins:

• Chicken: Use boneless, skinless chicken thighs or breasts (cut into strips)
• Shrimp: Needs only 15-20 minutes in the oven
• Salmon: Use thick fillets, reduce time to 20-25 minutes
• Sausage: Smoked sausage sliced into rounds works great

Vegetable Swaps:

• Instead of broccoli: Try green beans, asparagus, or zucchini
• Instead of mushrooms: Bell peppers, cherry tomatoes, or snap peas
• Instead of potatoes: Sweet potatoes (my personal favorite!), baby carrots, or butternut squash cubes

Flavor Variations:

Italian Style:

• Add cherry tomatoes, Italian seasoning, and top with mozzarella in the last 5 minutes

Cajun Style:

• Season with Cajun spice blend, add bell peppers and andouille sausage

Asian-Inspired:

• Use soy sauce instead of olive oil, add ginger and sesame oil, top with green onions

Tex-Mex:

• Season with taco seasoning, add bell peppers, top with cheese and serve with salsa

Storage and Reheating Instructions

These actually reheat beautifully, so don’t hesitate to make extra!

Refrigerator:

• Let cool completely first
• Store in airtight containers (or leave in foil)
• Keeps for 3-4 days

Freezer:

• Cool completely
• Portion into freezer-safe containers
• Freeze for up to 3 months
• Thaw overnight in fridge before reheating

Reheating:

• Oven (best method): Wrap in foil, reheat at 350°F for 15-20 minutes until warmed through
• Microwave: Transfer to microwave-safe dish, cover, heat in 1-2 minute intervals
• Stovetop: Heat in a skillet with a splash of broth until warmed through

Pro tip: Add a tiny bit of butter or broth when reheating to restore moisture!

Make-Ahead Instructions for Meal Prep

Want to prep these ahead for crazy-busy weeks? Here’s how:

Option 1 – Prep Ingredients:

• Chop all veggies and store in separate containers
• Slice steak and store separately
• Assemble packets the night before or morning of
• Refrigerate until ready to bake
• Add 5 minutes to cooking time if baking from cold

Option 2 – Fully Assemble:

• Make complete packets up to 24 hours ahead
• Refrigerate uncooked
• Bake when ready (add 5 extra minutes)

Option 3 – Cook and Freeze:

• Make the full recipe
• Cool completely
• Freeze individual portions
• Thaw and reheat as needed

I usually do Option 2 on Sunday afternoons – I’ll make 4-6 packets for the week ahead. Then on crazy weeknights, I just pull them from the fridge and pop them in the oven!

Common Problems & Solutions

Problem: Steak is tough

Solutions:

• You overcooked it! Try 145°F for medium instead of well-done
• Cut against the grain when slicing (this is crucial!)
• Use a more tender cut like ribeye or strip steak
• Marinate the steak for 2-4 hours before assembling

Problem: Potatoes aren’t tender

Solutions:

• Cut them smaller (halve or quarter large ones)
• Par-boil for 5 minutes before adding to packets
• Use baby potatoes or fingerlings (they’re more tender)
• Give them an extra 10 minutes in the oven

Problem: Broccoli is mushy

Solutions:

• Cut into larger florets
• Add broccoli halfway through cooking (at 15-minute mark)
• Use fresh instead of frozen

Problem: Everything is dry

Solutions:

• Make sure packets are tightly sealed (steam creates moisture!)
• Add 2 tablespoons chicken broth or water to each packet
• Don’t overbake – check at 25 minutes
• Use more olive oil (up to 3 tablespoons per packet)

Problem: Foil packets leaked

Solutions:

• Use heavy-duty foil (worth the investment!)
• Double-layer your foil in a “T” shape
• Don’t overfill packets
• Seal edges more tightly with multiple folds

Tips for Perfect Steak Foil Packets Every Time

After making these literally hundreds of times, here’s my wisdom:

1. Don’t skip the double-layer foil: Yes, it uses more foil, but leak-proof packets are worth it!

2. Cut ingredients uniformly: Everything should be roughly the same size so it cooks at the same rate.

3. Don’t overcrowd: Leave some space in the packet for steam to circulate. If you have a lot of ingredients, make more packets instead of stuffing them.

4. Use heavy-duty foil: Regular foil tears too easily. Heavy-duty is essential.

5. Add liquid for extra moisture: A splash of chicken broth, wine, or even just water helps create steam.

6. Let them rest: Don’t skip the 5-10 minute rest after adding butter. This makes all the difference!

7. Make extra: These reheat so well, I always make 6 packets even if I only need 2 for dinner. Future me is always grateful!

8. Label packets if customizing: Use a Sharpie on the foil to write whose packet is whose (especially helpful with picky eaters!).
