You know those last stubborn green tomatoes clinging to your vines before the first frost? I used to watch them wither away sadly – until I discovered green tomato ketchup! This tangy-sweet condiment became my favorite way to rescue those unripe gems. My first batch happened by accident when I panicked during an early freeze warning – now I actually hope for a few green tomatoes each season just to make it.
What makes green tomato ketchup so special? It’s got this bright, slightly tart flavor that regular ketchup can’t match, with warm spice notes that make it incredible on everything from morning eggs to grilled cheese. The first time I tasted it at my neighbor’s farm stand, I nearly dropped my hot dog – who knew something so good could come from “failed” tomatoes?
This recipe transforms what most gardeners consider waste into something magical. That sharp green tomato tang mellows into the perfect balance with brown sugar and spices, creating a ketchup that’ll make you wonder why we ever settled for the plain red stuff.

Why You’ll Love This Green Tomato Ketchup
This isn’t your average ketchup – it’s a flavor revelation that’ll make you rethink everything in your condiment drawer. Here’s why it’s become my go-to:
- That unforgettable tang: The green tomatoes give it a bright, slightly tart kick that regular ketchup just can’t match
- No waste wonder: Turns those end-of-season unripe tomatoes into something spectacular instead of compost
- Easier than you’d think: Just chop, simmer, and blend – no fancy equipment needed
- Make it your own: Dial up the cayenne for heat or add extra cinnamon for warmth
- Miles better than store-bought: Once you taste homemade, you’ll never go back to that overly sweet red stuff
Trust me, your burgers (and breakfasts!) will never be the same.
Green Tomato Ketchup Ingredients
Here’s everything you’ll need to make this magical condiment:
- 2 lbs green tomatoes, chopped (about 4 cups)
- 1 medium onion, chopped (about 1 cup)
- 1/2 cup apple cider vinegar
- 1/2 cup packed brown sugar
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp ground cloves
- 1/2 tsp cinnamon
- 1/4 tsp cayenne pepper
Ingredient Notes
Green tomatoes are essential here – their firm texture and tart flavor create the perfect base. Red tomatoes would make it too sweet and watery. For vinegar, apple cider gives the best flavor, but white vinegar works in a pinch (just use a bit less).
The spice blend is where you can get creative – I sometimes add extra cinnamon for warmth or double the cayenne for heat. Unlike red tomato ketchup, this version stays slightly thicker with more texture from the tomato skins – don’t worry, it blends smooth!
How to Make Green Tomato Ketchup
Ready to turn those green tomatoes into something magical? Here’s exactly how I make my favorite tangy condiment:
- The chop: Toss your chopped green tomatoes and onion into a large pot with the apple cider vinegar. No need to peel – those skins will blend right in later!
- The simmer: Cook over medium heat (that’s about a 5 on my stove) until everything gets nice and soft, about 15 minutes. You’ll know it’s ready when you can easily squish a tomato piece against the pot’s side.
- The blend: Carefully transfer everything to your blender (I use my immersion blender right in the pot) and puree until smooth. Watch out – it’s hot!
- The magic: Return the mixture to the pot and stir in all those wonderful spices – brown sugar, salt, pepper, cloves, cinnamon, and cayenne. This is where the flavor really comes alive!
- The patience test: Reduce heat to low (just barely bubbling) and let it simmer uncovered for 45 minutes, stirring occasionally. The ketchup will thicken and darken slightly – that’s when you know it’s perfect.
Sterilizing Jars Properly
While your ketchup simmers, prep your jars! I wash mine in hot soapy water, then submerge them in boiling water for 10 minutes. For long-term storage, process filled jars in a water bath for 15 minutes – this seals them tight so your ketchup keeps for months. Just listen for that satisfying “pop” as they cool!
Green Tomato Ketchup Storage Tips
Here’s how to keep your precious green tomato ketchup tasting its best:
If you’re planning to use it within a month (trust me, you will!), just pop it in the fridge in an airtight jar. For longer storage, those properly sealed and processed jars can sit happily in your pantry for up to a year – though I doubt they’ll last that long once you start using it!
Watch for any signs of trouble – if the lid bulges, the ketchup changes color, or you see mold, toss it immediately. Properly stored batches should keep that vibrant greenish-gold hue and tangy aroma. A little separation is normal – just give it a stir before using.
Serving Suggestions for Green Tomato Ketchup
Oh, don’t you dare limit this vibrant green tomato ketchup to just burgers – it’s way too special for that! My absolute favorite way is swirled into morning scrambled eggs – the tangy-sweet punch wakes up your taste buds better than coffee. Try it on these:
- Cheese plate superstar: Pair with sharp cheddar or creamy brie for an unexpected flavor combo
- Marinade magic: Brush it on chicken or pork before grilling – the acidity tenderizes while the caramelized sugars create the most incredible crust
- Breakfast game-changer: Drizzle over avocado toast or mix into your breakfast sandwich sauce
- Veggie dip delight: Thin with a little yogurt for the most addictive crudité dip
I even sneak it into meatloaf glaze – once you start using green tomato ketchup, you’ll find endless ways to enjoy it!

Green Tomato Ketchup FAQs
I get asked about this magical green tomato ketchup all the time – here are the top questions from my fellow condiment lovers:
Can I use ripe red tomatoes instead? Oh honey, don’t do it! The magic is in those tart green tomatoes – red ones will make it too sweet and watery. If you’re out of greens, try adding extra vinegar to balance the sweetness, but it just won’t have that signature bright tang we love.
How long does homemade green tomato ketchup last? In the fridge, about a month (if you can resist eating it all). Properly canned jars? A whole year! Just store in a cool, dark place and always check for weird smells or colors before using.
Is this spicier than store-bought ketchup? It’s got more personality! That 1/4 tsp cayenne gives it a gentle warmth, but feel free to adjust – my neighbor Mike doubles it for what he calls “firecracker ketchup.” The cloves and cinnamon add warmth rather than heat, making it way more complex than your average bottle.
