In this complete guide, we’re going to walk through everything — the materials you’ll need, the stitches you’ll use, the exact steps to crochet each component of the burger, and how to assemble it all into a finished keychain you’ll be proud to show off (or gift to your most food-obsessed friend). So grab your hook, pull up your favorite playlist, and let’s get crocheting.
Why Crochet Keychains Are Such a Great Project
Before we dive into the how-to, let’s take a moment to appreciate why crochet keychains — and miniature food crochet in particular — have taken the crafting world by storm. These tiny projects are the perfect way to use up yarn scraps. They work up in an hour or two, which means you get that satisfying “I made this!” feeling much faster than you would from a blanket or garment. They make incredible handmade gifts that feel personal and thoughtful without requiring weeks of effort. And they’re endlessly customizable. Once you understand the basic technique, you can adjust colors, sizes, and ingredients to make the burger of your dreams.
The crochet burger keychain is especially beloved because it’s built from individual components — a top bun, a bottom bun, a patty, cheese, lettuce, and tomato — each crocheted separately and then layered together. This makes it a fantastic introduction to amigurumi-style construction, where three-dimensional objects are built by crocheting in the round and stuffing each piece before assembly.
Materials You’ll Need
Getting your supplies together before you start is one of the best habits you can build as a crocheter. Here’s everything you’ll need for this project.
Yarn: You’ll want a small amount of yarn in several colors. The specific shades will make your burger look realistic and delicious. Choose a warm tan or beige for the top and bottom buns, a warm dark brown for the beef patty, bright yellow for the cheese, medium green for the lettuce, and red for the tomato. Worsted weight yarn works beautifully for this project and gives the finished pieces a satisfying, chunky look, but you can absolutely use DK weight for a slightly smaller burger. The brand doesn’t matter much here — this is a great stash-buster project.
Crochet Hook: A 3.5mm to 4mm hook is ideal for worsted weight yarn. You want your stitches to be tight enough that the stuffing doesn’t peek through the gaps, so if your tension is loose, size down.
Polyester Fiberfill: You’ll use this to stuff the buns and the patty. Just a small amount will do — don’t overstuff, or your burger will look more like a balloon than a sandwich.
Yarn Needle: Essential for weaving in ends and for the sewing-together assembly steps.
Scissors: Any sharp pair will work.
Stitch Marker: Helpful for keeping track of where your rounds begin and end when you’re crocheting in the round.
Keychain Ring: A simple split ring or lobster clasp keychain finding, available at any craft store or online.
Black Embroidery Floss or Yarn (Optional): For adding sesame seeds to the top bun, if you want extra detail.
Understanding the Basic Stitches
This pattern uses a handful of fundamental crochet stitches. If you’re already comfortable with these, feel free to skip ahead. If you’re newer to crochet, here’s a quick refresher.
Magic Ring (MR): Also called a magic circle, this is how you’ll start most of your circular pieces. It creates a tight, invisible center for working in the round.
Single Crochet (sc): The foundational stitch of amigurumi. You’ll use this for almost every part of the burger.
Increase (inc): Two single crochets worked into the same stitch, which expands your circle outward.
Decrease (dec): An invisible decrease worked across two stitches, which pulls your circle inward.
Slip Stitch (sl st): Used to finish rounds and join pieces together neatly.
Chain (ch): A basic chain of yarn that can be used for the keychain loop attachment.
All abbreviations in this pattern follow US crochet standards.
Part One: The Bottom Bun
The bottom bun is a slightly flattened disc, and it forms the foundation of your entire burger. Start with your tan or beige yarn.
Round 1: Start with a magic ring. Work 6 single crochets into the ring, then pull the tail to close the center. (6 stitches)
Round 2: Work 2 single crochets into each stitch around. (12 stitches)
Round 3: Single crochet in the first stitch, then 2 single crochets in the next. Repeat this pattern — one regular stitch, then one increase — all the way around. (18 stitches)
Round 4: Single crochet in the first two stitches, then 2 single crochets in the third. Continue this pattern all the way around. (24 stitches)
Round 5: Single crochet in the first three stitches, then 2 single crochets in the fourth. Repeat around. (30 stitches)
Rounds 6 through 8: Single crochet in each stitch around for three rounds, keeping the stitch count at 30.
At this point, your bottom bun should look like a small, rounded disc. The back of your work (the side facing away from you as you crochet) will form the flat underside of the bun, and the front will be slightly domed. Before you close this piece, stuff it lightly with fiberfill — just enough to give it a gentle puffiness.
Round 9: Single crochet in the first three stitches, then work an invisible decrease over the next two. Repeat this pattern around. (24 stitches)
Round 10: Single crochet in the first two stitches, then decrease. Repeat around. (18 stitches)
Fasten off, leaving a long tail for sewing. You don’t need to close this piece completely — the open side will face upward to receive all the burger layers.
Part Two: The Top Bun
The top bun is made very similarly to the bottom bun but with a slightly more pronounced dome shape. Use the same tan or beige yarn.
Follow Rounds 1 through 5 exactly as you did for the bottom bun, increasing to 30 stitches.
Rounds 6 through 10: Single crochet in each stitch around for five rounds. This extra length creates the taller, rounder shape of the top of a burger bun.
Stuff gently as you close the piece.
Round 11: Single crochet in the first three stitches, decrease. Repeat around. (24 stitches)
Round 12: Single crochet in the first two stitches, decrease. Repeat around. (18 stitches)
Round 13: Single crochet in the first stitch, decrease. Repeat around. (12 stitches)
Round 14: Decrease around. (6 stitches)
Fasten off, leaving a long tail. Use your yarn needle to close the remaining gap by weaving through the front loops of those last 6 stitches and pulling tight.
This is also the piece where you’ll attach your keychain ring. Before you fully close the top of the bun, cut a short length of your tan yarn (about 6 inches), fold it in half, and use a latch hook or your crochet hook to pull the folded loop through the top center stitch. Thread the two tail ends through the keychain ring and tie them off in a secure knot. Alternatively, crochet a short chain of about 6 stitches, fold it into a loop, and attach it to the top of the bun before closing.
If you’d like to add sesame seeds, use a few small straight stitches with white or cream embroidery floss across the dome of the top bun. It’s an optional detail, but it makes a huge difference in how realistic the finished burger looks.
Part Three: The Beef Patty
Use your dark brown yarn for this piece. The patty is a flat, slightly irregular disc — it doesn’t need to be perfectly round, because real burger patties never are.
Round 1: Magic ring, 6 single crochets. (6 stitches)
Round 2: Increase in each stitch. (12 stitches)
Round 3: Single crochet, increase. Repeat around. (18 stitches)
Round 4: Single crochet in the next two stitches, increase. Repeat around. (24 stitches)
Round 5: Single crochet in the next three stitches, increase. Repeat around. (30 stitches)
Rounds 6 and 7: Single crochet in each stitch around.
Round 8: Single crochet in the next three stitches, decrease. Repeat around. (24 stitches)
Round 9: Single crochet in the next two stitches, decrease. Repeat around. (18 stitches)
Add a tiny amount of stuffing — even less than the buns. The patty should be mostly flat with just a hint of thickness.
Round 10: Single crochet in the next stitch, decrease. Repeat around. (12 stitches)
Fasten off and close the remaining stitches with your needle, leaving a long tail for sewing.
Part Four: The Cheese Slice
The cheese is one of the most fun parts because its slightly droopy corners are what give the burger its iconic, appetizing look. Use yellow yarn for this piece.
Unlike the circular pieces, the cheese is worked in rows to create a square shape.
Foundation chain: Chain 14.
Row 1: Single crochet in the second chain from the hook and in each chain across. (13 stitches) Chain 1, turn.
Rows 2 through 13: Single crochet in each stitch across. Chain 1, turn at the end of each row.
After 13 rows, you should have a rough square. Fasten off and weave in your ends. Don’t worry about making this perfectly flat or stiff — the yarn’s natural drape will create that wonderful cheese-melting-over-the-edge effect when you assemble the burger.
Part Five: The Lettuce
Lettuce is where you can really have fun with texture. Use medium green yarn.
Round 1: Magic ring, 6 single crochets. (6 stitches)
Round 2: Increase in each stitch. (12 stitches)
Round 3: Single crochet, increase. Repeat around. (18 stitches)
Round 4: Single crochet in the next two, increase. Repeat around. (24 stitches)
Round 5: Single crochet in the next three, increase. Repeat around. (30 stitches)
Now here is where the lettuce gets its distinctive ruffled edge. For the next round, work 3 single crochets into every stitch around the edge. This aggressive increase creates a frill that mimics the crinkled, ruffled look of a leaf of iceberg lettuce.
Fasten off, leaving a long tail. This piece stays flat and doesn’t get stuffed.
Part Six: The Tomato
Use red yarn for the tomato. It’s similar to the patty but slightly smaller and thinner.
Round 1: Magic ring, 6 single crochets. (6 stitches)
Round 2: Increase in each stitch. (12 stitches)
Round 3: Single crochet, increase. Repeat around. (18 stitches)
Round 4: Single crochet in the next two, increase. Repeat around. (24 stitches)
Rounds 5 and 6: Single crochet in each stitch around.
Round 7: Single crochet in the next two, decrease. Repeat around. (18 stitches)
Round 8: Single crochet, decrease. Repeat around. (12 stitches)
Add the thinnest whisper of stuffing to give a barely-there dimension, then fasten off and close with your needle.
Assembling Your Crochet Burger Keychain
This is the moment everything comes together, and honestly it’s immensely satisfying to watch the burger take shape in your hands. Lay all your finished pieces out in front of you: bottom bun, tomato, lettuce, cheese, patty, top bun.
Using your yarn needle and the long tails you left on each piece, sew the components together in layers, working from the bottom up. Start by stitching the tomato onto the top surface of the bottom bun, using whipstitch around the outer edge. Next, lay the lettuce on top of the tomato and stitch it in place the same way. Then comes the cheese — drape it across the lettuce and let the corners fall naturally over the edges. Tack it down with just a few stitches in the center and perhaps one stitch on each corner to keep it from shifting. Place the patty on top of the cheese and sew it around its perimeter.
Finally, position the top bun on the patty and sew it down, working all the way around to secure it firmly. Give the entire stack a gentle squeeze to seat all the layers together, and adjust anything that looks off-center.
Your burger keychain is now fully assembled. Your keychain ring should already be attached to the top of the upper bun. If you haven’t done that step yet, now is the time — use a small crochet hook to pull a loop of yarn through the topmost stitch, thread it through your keychain ring, and tie it securely.
Tips for Making Your Burger Even Better
A few tricks can elevate your finished piece from cute to truly impressive. First, pay attention to stuffing — too much and your burger looks like it was inflated, too little and the buns lose their shape. Aim for firm but not taut. Second, when sewing the layers together, it helps to pin them with a few straight pins before committing with your needle. This ensures everything stays centered as you work. Third, if your yarn tends to split while crocheting, try working more slowly and consciously directing the hook under all plies of the stitch. Fourth, blocking — lightly misting your finished pieces with water and allowing them to dry flat — can smooth out any uneven stitches and give your burger a more polished appearance.
Customizing Your Crochet Burger
Once you’ve made the basic version, the possibilities are wide open. Add a sunny yellow half-circle piece for mustard. Make a small white oval with red swirl embroidery for a fried egg. Use orange yarn instead of yellow for cheddar. Give your patty a lighter center and darker edges using a simple color change to simulate a sear. Make a sesame seed bun by switching to a speckled yarn or adding tiny French knots across the top. You can even crochet a slice of bacon using alternating stripes of pink and dark red chain stitches.
These keychains also make wonderful gifts arranged as a “set” — imagine a little burger, a packet of fries, and a tiny drink charm all on the same ring. Once you’ve mastered the technique here, scaling it into a complete fast food meal is absolutely achievable.
A Final Note on Enjoying the Process
Mini crochet projects like this burger keychain are about more than the finished object. They’re about the meditative rhythm of stitching, the thrill of watching something three-dimensional emerge from a flat ball of yarn, and the joy of sharing what you’ve made with people you love. Keep your finished burger in a small zip bag if you’re gifting it, and consider adding a little handwritten tag that says “made with love” — because it genuinely was.
Happy crocheting, and may your burgers be perfectly stacked.
