during a weekend camping trip to the Appalachian foothills with my daughter and her two little ones, we found ourselves craving something warm, hearty, and easy to make with minimal cleanup. The rain had chased us into the camper, and we huddled around the little air fryer we’d packed more as an afterthought than a plan.
I remembered this old foil-packet method my grandmother used when she’d take us fishing. She’d toss potatoes and sausage into foil and roast them over the fire. That memory lit a spark, and I figured—why not try a low-carb version with what we had on hand?
We had ground beef, a pouch of onion soup mix, a zucchini and squash we picked up from a roadside farm stand, and some shredded cheddar leftover from lunch. My daughter gave me that skeptical “are you sure this is going to work?” look. I just smiled and told her to trust me. As the rain drummed on the camper roof, the air fryer hummed quietly, and the smell that filled our little space was cozy, rich, and downright irresistible.
When we unwrapped those foil packets and steam rose in gentle curls, I saw my grandkids dive in like it was Christmas morning. Simple. Satisfying. And somehow, in that moment—sitting on camping chairs with plastic forks and paper plates—it felt like one of the best meals we’d had all summer.
Short Description
These Keto Cheeseburger Air Fryer Foil Packets are a low-carb, flavor-packed meal with juicy burger patties, tender summer veggies, and melty cheddar—all wrapped in foil and cooked effortlessly in the air fryer.
Key Ingredients
- 1 pound ground beef
- 1 tsp onion soup mix
- 1 zucchini, sliced and halved
- 1 yellow squash, sliced and halved
- 1 cup shredded cheddar cheese
- Salt and pepper, to taste
Tools Needed
- Air fryer
- Mixing bowl
- Measuring spoons
- Knife and cutting board
- Aluminum foil
- Tongs or spatula
Cooking Instructions
Step 1: Preheat the Air Fryer
Set your air fryer to 400°F. This ensures the patties cook evenly and develop a flavorful exterior.
Step 2: Prepare the Beef Patties
In a mixing bowl, combine ground beef and onion soup mix. Use your hands to knead until well mixed. Divide into 4 equal portions and shape into patties.
Step 3: Season the Veggies
Sprinkle the zucchini and yellow squash with salt and pepper. Set aside while you prep the foil packets.
Step 4: Assemble the Foil Packets
Tear 4 long sheets of aluminum foil and lay them flat. In the center of each, add a layer of the seasoned squash and zucchini. Place one beef patty on top. Sprinkle each with shredded cheddar.
Step 5: Fold and Seal
Fold the long sides of the foil over the burger, then roll up the edges tightly to seal each packet. Make sure they’re well-sealed to trap in steam and flavor.
Step 6: Air Fry the Packets
Place the foil packets in the air fryer basket in a single layer. Cook at 400°F for 25 minutes. The burgers should be fully cooked and the veggies tender. If unsure, use a meat thermometer—look for 160°F at the center.
Step 7: Serve and Enjoy
Let the packets cool for a minute before carefully unsealing (steam will escape). Transfer to a plate or enjoy straight from the foil for easy cleanup.

Mistakes to Avoid & Solutions
1. Overpacking foil packets
Too many veggies or thick patties can slow cooking.
Solution: Keep patties ½–¾ inch thick and veggies in a thin layer.
2. Underseasoning the vegetables
Zucchini and squash can taste bland if not seasoned.
Solution: Salt and pepper generously before adding them to the foil.
3. Foil not sealed tightly
Loose packets may leak juices or dry out.
Solution: Double-fold the seams and crimp the ends tightly.
4. Using lean beef only
Extra-lean meat can turn dry.
Solution: Use 80/20 ground beef for juicy results.
5. Opening the packets too soon
Steam can burn or cool the food too quickly.
Solution: Let them rest for 1–2 minutes before unsealing.
Serving and Pairing Suggestions
These foil packets are satisfying on their own, but you can dress them up with:
– A side salad with ranch or vinaigrette
– Cauliflower mash or roasted broccoli
– A drizzle of sugar-free ketchup or mustard
– Served family-style on a big tray at a BBQ
– Packed in a lunchbox with pickle spears on the side
Storage and Reheating Tips
Storage:
Refrigerate leftovers in their foil for up to 3 days. Place packets in an airtight container to prevent moisture loss.
Reheating:
Air fryer: 350°F for 6–8 minutes
Oven: Bake at 350°F in foil for 10 minutes
Microwave: Remove from foil, place in a microwave-safe dish, and heat in 30-second intervals
FAQs
1. Can I use ground turkey instead of beef?
Yes, but add a tablespoon of olive oil to keep it moist, as turkey is leaner.
2. Is the onion soup mix keto-friendly?
Many store-bought mixes have added sugar or starch. Look for a keto version or make your own with dried onion, garlic powder, and herbs.
3. Can I add more vegetables?
Absolutely! Bell peppers, mushrooms, or spinach work great—just keep the total veggie volume moderate.
4. Do I need to flip the packets during cooking?
No flipping needed. The air fryer circulates heat evenly around the packets.
5. Can I prep these in advance?
Yes! Assemble the foil packets and refrigerate for up to 24 hours before cooking.
Tips & Tricks
Use nonstick foil for easy cleanup and no sticking.
Add a small dollop of mustard or hot sauce inside the packet for extra flavor.
Let patties rest at room temperature for 10 minutes before cooking to ensure even doneness.
Don’t open the foil too quickly—let the packets rest a minute for best flavor and moisture.
Cheese tends to stick—sprinkle it closer to the center of the patty, away from edges.
Recipe Variations
1. Spicy Jalapeño Version
Add sliced jalapeños and pepper jack cheese
Mix 1 tsp chili powder into the beef
Top with hot sauce before sealing foil
Cook time remains the same
2. BBQ Ranch Twist
Mix 2 tbsp sugar-free BBQ sauce into the meat
Use colby jack instead of cheddar
Add sliced red onion and a drizzle of ranch dressing after cooking
3. Mushroom & Swiss Style
Swap cheddar for Swiss cheese
Add ¼ cup sautéed mushrooms to each foil packet
Mix a dash of Worcestershire sauce into the ground beef
Final Thoughts
That rainy night in the camper turned into one of those core memories we keep close. Not because the meal was fancy or the day went smoothly, but because it brought us together over something warm and comforting. My daughter still jokes that I can MacGyver a five-star dinner out of anything, but she’s the one who called last week asking for this exact recipe.
The kids remembered it too—“Grandma’s cheeseburger surprise in a pouch,” they call it. It’s funny how food doesn’t just fill our stomachs—it tucks itself into stories we’ll tell again and again. And if a recipe can do that? Well, it’s a keeper.
