Ingredients

Alright, gather ’round! You don’t need much for this magic to happen. Here’s what you’ll want to have on hand:

Ground beef: About 8 ounces, which we’ll split into two 4oz portions. I usually go for 80/20 for flavor, but use what you like!

Water or beef broth: Just a couple tablespoons (1 per packet). This little trick helps keep the burgers moist and juicy inside the foil.
Salt and Pepper: To taste, of course. Season that meat!
Diced onion: (Optional, 2 tbsp total). If you love cooked onions on your burger, definitely add these in. They get lovely and tender in the packet.

Sugar-free ketchup: 2 tablespoons (1 per packet). Adds that essential sweet and tangy note without the sugar.
Mustard: 2 tablespoons (1 per packet). Can’t have a cheeseburger without that classic mustard tang!
Cheddar cheese slices: 2 slices (1 per packet). Use your favorite kind of cheddar – sharp, mild, whatever melts your heart!

Low-carb buns or lettuce wraps: (Optional, for serving). You can eat these patties right out of the packet, or serve them up low-carb style!

How to Make It

Okay, let’s get cooking! It’s ridiculously simple, I promise.

First things first, get your air fryer warming up. Set it to 375°F (190°C).
While it’s heating, grab your heavy-duty aluminum foil. You’ll need two pieces, roughly 8×10 inches each. Heavy-duty is key here so it doesn’t tear easily.

In a small bowl, gently combine your ground beef, water or broth, salt, pepper, and the diced onion if you’re using it. Don’t overmix! Just bring it together. Then, form the mixture into two small patties.
Lay out your two pieces of foil flat. Place one patty on one side of each foil piece.
Now for the toppings! Dollop 1 tablespoon of sugar-free ketchup and 1 tablespoon of mustard right on top of each patty.

Place one glorious slice of cheddar cheese over the ketchup and mustard on each patty.
Time to seal the deal! Carefully fold the foil over the patty and all those delicious fillings. Crimp the edges tightly to create a sealed packet. You want to make sure everything is locked inside so it steams and cooks perfectly.
Carefully place your two foil packets into the air fryer basket. Make sure they aren’t overlapping if possible, though with just two, they should fit nicely side-by-side in most baskets.

Cook for 10–12 minutes. The exact time can vary slightly depending on your air fryer and how thick your patties are, but 10-12 minutes is usually perfect for fully cooked, juicy burgers with melted cheese.
Once the time is up, carefully remove the packets from the air fryer. Open them up (watch out for hot steam!). Your cheeseburger patties are ready! Serve them warm – either sliding them out onto a plate, or placing them on your favorite low-carb bun or wrapping them in fresh lettuce.

Substitutions & Additions

Want to mix things up or add your own flair? Go for it! These packets are super flexible.

Cheese Swap: Not feeling cheddar? Try provolone, Monterey Jack, pepper jack for a kick, or even a sprinkle of mozzarella.
Add-ins: Before sealing the packets, you could add cooked, crumbled bacon, sliced mushrooms, diced bell peppers, or a few jalapeño slices for heat.
Sauce It Up: Instead of or in addition to ketchup and mustard, try a sugar-free BBQ sauce, a dollop of mayo, or a sprinkle of garlic powder and onion powder mixed into the meat.

Protein: While this recipe is designed for ground beef, you could potentially adapt it for ground turkey or chicken, though cooking times might vary slightly.

Tips for Success

Just a couple little pointers to make sure your packets turn out perfectly every time:

Use Heavy-Duty Foil: Trust me on this. Regular foil is more likely to tear, and you don’t want any leaks in your air fryer basket!

Seal Tightly: Make sure those edges are crimped well to keep all the juices and cheese locked inside.
Don’t Overstuff: Stick to the portion sizes so the packets seal properly and cook evenly.
Check for Doneness: If you’re unsure, use a meat thermometer. Ground beef should reach an internal temperature of 160°F (71°C).

Watch the Steam: Seriously, when you open these packets, they release a puff of hot steam. Open them carefully away from your face!

Storage Instructions

Got leftovers? (It doesn’t happen often in my house!).

You can store cooked cheeseburger patties from the foil packets in an airtight container in the refrigerator for 3-4 days. To reheat, you can pop them back into a new foil packet or directly in the air fryer (or even microwave) until heated through.

FAQ

Can I use regular ketchup and mustard?: Yes, absolutely, but the recipe won’t be keto or low-carb if you use the sugar-sweetened versions.
Can I make more than two packets at once?: You can, as long as they fit comfortably in your air fryer basket without overlapping too much. If they are too crowded, you may need to cook them in batches for best results.
What kind of ground beef is best?: I like 80/20 for flavor, but leaner options like 90/10 will work too. The broth/water helps keep leaner meats moist.
Can I cook these in a regular oven?: Yes! Preheat your oven to around 400°F (200°C). Place the packets on a baking sheet and bake for 15-20 minutes, or until cooked through. The air fryer is just faster and gets things nicely melty!
