Vegetarian Chorizo Spinach Cheese Puffs

There are some recipes I’m perfectly happy to spend all afternoon making.

Ketchup is not one of them.

If I’m making homemade ketchup, I want something that tastes properly tomatoey, has that familiar sweet-and-tangy flavour, actually sticks to a chip instead of running off it — and doesn’t require me to babysit a slow cooker for twelve hours.

That is exactly why this easy homemade ketchup recipe starts with tomato paste.

You get the concentrated tomato flavour and thick consistency straight away, which means the whole thing can be simmered on the stove in about 15 to 20 minutes.

No peeling tomatoes.

No straining seeds.

No reducing two cans of tomatoes for half a day.

And perhaps most importantly, you control how sweet it is.

Anyone who has made ketchup before will know this is surprisingly important. Tomatoes vary, people’s taste buds vary, and what one person calls perfectly sweet another person calls tomato jam.

So we’ll start modestly and adjust at the end.

Why You’ll Love This Homemade Ketchup Recipe

This is the sort of homemade condiment recipe that’s actually practical enough to make again.

It is:

• Ready in about 20 minutes
• Made from basic pantry ingredients
• Smooth and thick without cornstarch
• Easy to make sweeter or tangier
• Much quicker than ketchup made from crushed tomatoes
• Suitable for small batches
• Freezer-friendly
• Naturally easy to customise

And once you’ve made one jar, you’ll suddenly start wondering what else you could stop buying.

That little homemade-pantry-staple rabbit hole is dangerous.

One minute you’re making ketchup and the next you’re standing over a pot of sauce feeling extremely self-sufficient.

Easy Homemade Ketchup Recipe

Prep time: 5 minutes
Cook time: 15–20 minutes
Total time: About 25 minutes
Yield: Approximately 1 1/2 cups

Ingredients

• 1 cup tomato paste
• 3/4 cup water
• 1/4 cup apple cider vinegar
• 3 tablespoons brown sugar
• 1 tablespoon white sugar, optional
• 1 teaspoon onion powder
• 1/2 teaspoon garlic powder
• 1/2 teaspoon fine salt
• 1/4 teaspoon mustard powder
• 1/8 teaspoon celery salt
• 1/8 teaspoon ground cinnamon
• Tiny pinch ground cloves
• Tiny pinch ground allspice
• Pinch cayenne pepper, optional

How to Make Homemade Ketchup

Step 1: Combine Everything in a Saucepan

Add the tomato paste, water, apple cider vinegar, brown sugar, onion powder, garlic powder, salt, mustard powder, celery salt, cinnamon, cloves, allspice and cayenne if using to a small saucepan.

Whisk until smooth.

It will look slightly thinner than bottled ketchup at this stage. That’s exactly what you want because it thickens as it cooks and then thickens a little more as it cools.

Step 2: Bring It to a Gentle Simmer

Place the saucepan over medium heat and bring the mixture to a gentle simmer.

Once you see small bubbles appearing, reduce the heat to low.

You don’t want ketchup enthusiastically erupting all over your stovetop. Tomato sauce has a remarkable ability to splatter somewhere you didn’t even know was within range.

Step 3: Simmer Until Thick

Cook uncovered for approximately 15 to 20 minutes, stirring regularly.

The ketchup should become darker, glossier and noticeably thicker.

Drag your spoon across the bottom of the saucepan. If the sauce slowly closes over the line rather than immediately flooding back in, you’re getting close.

Step 4: Taste Before Adding More Sugar

Now taste it.

This is important.

If you’d like your homemade ketchup closer to a traditional bottled-ketchup flavour, stir in the additional tablespoon of white sugar.

If you prefer a tangier ketchup, leave it out.

If it needs more acidity, add another teaspoon or two of vinegar.

This is much easier than dumping a huge amount of sugar into the saucepan at the beginning and discovering ten minutes later that you’ve essentially created tomato cordial.

Step 5: Cool

Remove the saucepan from the heat and leave the ketchup to cool.

It will thicken further as it cools.

Transfer to a clean jar or bottle and refrigerate.

What Does Homemade Ketchup Taste Like?

This version is deliberately designed to taste familiar.

You should get:

Tomato first — not sugar.

Sweetness second — enough to balance the vinegar and tomato acidity.

Tanginess from apple cider vinegar.

And then those tiny background notes of mustard, celery, cinnamon, clove and allspice that make ketchup taste like ketchup rather than simply sweetened tomato sauce.

The spices should not jump out individually.

If somebody takes a bite and says, “Oh, cinnamon!” you’ve probably gone a little enthusiastic with the cinnamon.

Why Use Tomato Paste for Homemade Ketchup?

This is where my version deliberately takes a different path from many traditional homemade ketchup recipes.

Some recipes start with fresh or canned crushed tomatoes and slowly reduce them until they become thick enough.

That absolutely works.

But tomato paste has already been concentrated.

That means we’re essentially beginning several hours further along in the process.

For a weekday homemade condiment, I’ll happily take the shortcut.

Tomato Paste vs Fresh Tomatoes for Ketchup

Both methods have their place.

Tomato Paste Ketchup

Best when you want:

• Quick ketchup
• Reliable thickness
• Small batches
• Minimal preparation
• Consistent tomato flavour

Fresh Tomato Ketchup

Best when you have:

• A garden overflowing with tomatoes
• Plenty of time
• A food mill or sieve
• An interest in preserving a large batch

Fresh tomato ketchup generally requires considerably more reduction because tomatoes contain so much water.

If I’ve got three kilos of tomatoes threatening to collapse under their own weight on the kitchen bench, that’s when I’m making the long version.

If somebody wants chips tonight, I’m opening the tomato paste.

How to Make Homemade Ketchup Taste More Like Heinz

If you’re specifically chasing that familiar bottled-ketchup flavour, the key is balance rather than adding enormous amounts of sugar.

After the ketchup has simmered, taste it and adjust gradually.

For a sweeter commercial-style flavour:

• Add another 1 tablespoon white sugar
• Add 1 teaspoon vinegar if the sweetness starts overtaking the tang
• Add another tiny pinch of salt if everything tastes muted

Don’t keep adding spice.

The characteristic flavour of bottled ketchup is actually quite subtle.

How to Make Ketchup Less Sweet

This is one of the biggest advantages of making it yourself.

Start with the 3 tablespoons brown sugar only and omit the optional white sugar.

You can even reduce the brown sugar to 2 tablespoons if you prefer very tangy ketchup.

That’s one of the big advantages of homemade ketchup over supermarket versions — you can adjust it to suit your own taste rather than being stuck with whatever sweetness level comes in the bottle.

How to Make Homemade Ketchup Thicker

First, let it cool before deciding it is too thin.

Warm ketchup will always look looser.

If it is still thinner than you’d like after cooling, return it to the saucepan and simmer gently for another 5 minutes.

You shouldn’t need cornstarch for this tomato-paste version.

If your ketchup gets too thick, whisk in water one tablespoon at a time.

That’s far easier to fix than ketchup that’s been watered down too enthusiastically.

How to Make Homemade Ketchup Smoother

Because this recipe uses tomato paste and powdered seasonings, it should already be quite smooth.

For a particularly silky restaurant-style consistency, give it a quick blitz with a stick blender after cooking.

A basic immersion blender is one of those kitchen gadgets that’s surprisingly useful for sauces, soups and dips. You don’t need anything terribly fancy; even an inexpensive stick blender from Amazon will do the job perfectly well.

Can I Use White Vinegar Instead?

Yes.

Apple cider vinegar gives homemade ketchup a slightly rounded flavour, but distilled white vinegar works well too and gives you a sharper, more classic tang.

Use the same quantity.

For refrigerator ketchup, you can also experiment with different vinegars for flavour.

That flexibility changes if you’re canning it, however — more on that below.

Can I Use Honey Instead of Sugar?

For a refrigerated homemade ketchup, yes.

Try replacing the brown sugar with approximately 2 tablespoons honey, then taste once the ketchup has cooked.

Honey is sweeter than brown sugar, so I’d resist replacing it cup-for-cup.

It will also give the ketchup a slightly different flavour, which isn’t necessarily a bad thing.

Spicy Homemade Ketchup

Add:

• 1/4 teaspoon cayenne pepper
• 1/2 teaspoon smoked paprika
• Or a few drops of hot sauce

Start small.

You can always make ketchup hotter.

Removing cayenne after it’s in there requires considerably more advanced kitchen magic.

Smoky Ketchup

For burgers and barbecues, add:

• 1/2 teaspoon smoked paprika
• 1 teaspoon Worcestershire sauce

This takes the recipe slightly toward barbecue-sauce territory and is particularly good with grilled meats or potato wedges.

Homemade Curry Ketchup

If you’ve ever eaten German currywurst, you’ll know exactly where this is heading.

Stir approximately 1 teaspoon curry powder into the finished ketchup.

Add a little more if you like a stronger curry flavour.

It’s ridiculously good with fries.

What Can You Use Homemade Ketchup For?

Obviously:

• French fries
• Burgers
• Hot dogs
• Sausage rolls
• Meat pies
• Potato wedges
• Grilled cheese sandwiches
• Chicken nuggets

But ketchup is also an ingredient.

Use it in:

• Meatloaf glaze
• Barbecue sauce
• Cocktail sauce
• Burger sauce
• Sloppy Joes
• Sweet-and-sour sauces
• Marinades
• Homemade salad dressings

That’s why I prefer making it reasonably neutral rather than loading it with unusual spices.

You can always transform it later.

How Long Does Homemade Ketchup Last?

This recipe should be treated as refrigerator ketchup, not shelf-stable preserves.

Transfer the cooled ketchup to a clean airtight container and refrigerate it.

For a conservative home-kitchen approach, use it within approximately 2 weeks.

Always discard homemade condiments if you notice mould, bubbling, an unusual smell or other signs of spoilage.

Can You Freeze Homemade Ketchup?

Yes.

Ketchup freezes quite well.

Portion it into small freezer-safe containers, leaving a little room for expansion.

You can also freeze smaller quantities in silicone ice-cube trays and transfer the frozen portions into a freezer bag.

That’s particularly handy if you mostly use ketchup as an ingredient rather than a dipping sauce.

Can I Can This Homemade Ketchup?

Do not use this particular recipe for shelf-stable water-bath canning.

This recipe is designed for refrigerator storage.

Home canning is one area where I wouldn’t casually alter the vinegar, tomato or vegetable ratios from an untested recipe.

If you want shelf-stable homemade ketchup, use a tested canning recipe from a trusted preserving authority.

Fridge ketchup is forgiving.

Canning chemistry is not a place for creative improvisation.

Fresh Tomato Ketchup for Canning

If you’ve landed here because you’re staring at twenty kilos of garden tomatoes rather than one tin of tomato paste, use a tested preservation recipe instead.

Fresh tomato ketchup is a completely different job from our little weeknight jar of ketchup.

And frankly, if you’re tackling that many tomatoes, I salute you.

Common Homemade Ketchup Problems

My Ketchup Is Too Thin

Simmer it longer.

Keep the saucepan uncovered so water can evaporate.

Remember that it will also thicken as it cools.

My Ketchup Is Too Thick

Whisk in hot water one tablespoon at a time.

My Ketchup Is Too Sweet

Add apple cider vinegar one teaspoon at a time until the flavour balances.

My Ketchup Is Too Sour

Add another teaspoon or two of sugar.

My Ketchup Tastes Flat

Try salt first.

A tiny amount often fixes what seems like an entirely bigger problem.

I Can Taste the Cinnamon or Cloves

Use less next time.

These are background spices and should be barely noticeable individually.

Homemade Ketchup FAQ

Can homemade ketchup be made without sugar?

Yes, although it will taste considerably more acidic than traditional ketchup.

You could make it with no sweetener at all, or use a small amount of honey or another preferred sweetener.

Can I make ketchup without tomato paste?

Yes.

You can use crushed or fresh tomatoes, but they require much longer cooking to reduce their water content.

Does homemade ketchup need refrigeration?

Yes.

This recipe is not commercially processed or shelf stable. Keep it refrigerated.

Can kids eat homemade ketchup?

Of course. Simply omit the cayenne if your family prefers very mild ketchup.

One advantage of homemade ketchup is being able to control the salt, sugar and spice levels.

Why is my homemade ketchup darker than bottled ketchup?

That is normal.

Commercial ketchup is produced under tightly controlled conditions and brands are designed for very consistent colour.

Homemade ketchup often becomes a slightly deeper red as it cooks.

Is Catsup the Same as Ketchup?

For modern cooking purposes, yes.

You’ll still occasionally see the spelling catsup, particularly in older recipes, but both terms generally refer to the familiar tomato condiment.
