Should You Ripen or Cook Your Unripe Tomatoes?
As the end of the growing season approaches, you'll likely have a bounty of green tomatoes that haven't had a chance to turn red. Before deciding on a course of action, first, sort your harvest. Look for tomatoes that are a pale green or have a slight blush—these have the highest potential for ripening off the vine. The deeper green, firmer tomatoes are best suited for recipes where their tart flavor is a feature, not a flaw.
Methods for Ripening Tomatoes Indoors
There are several simple and effective ways to encourage green tomatoes to ripen once you've brought them inside. The process is driven by ethylene gas, a natural plant hormone.
- The Paper Bag Trick: For a small batch, place a few unripe tomatoes in a paper bag or a cardboard box. Add a ripe banana or apple, which are high ethylene producers, and seal the bag loosely to trap the gas. The added fruit will speed up the ripening process dramatically. Check the bag every few days and remove any that have fully ripened or started to spoil.
- The Cardboard Box Method: For a larger harvest, arrange unripe tomatoes in a single layer in a cardboard box, ensuring they don't touch each other. Place layers of newspaper or tissue paper between additional layers of tomatoes to prevent rot from spreading. Store the box in a cool, dark, and dry spot, like a basement or pantry. Temperatures between 60–65°F (15–18°C) are ideal.
- The Upside-Down Plant: If you have an entire plant still laden with green fruit as the first frost approaches, you can pull the whole plant up by the roots. Shake off any excess dirt and hang the plant upside down in a cool, dark, dry place, like a garage. The remaining nutrients in the vine will continue to ripen the fruits over several weeks.
Creative Recipes for Green Tomatoes
For the harder, paler green tomatoes that are unlikely to ripen, their firm texture and tangy flavor make them perfect for cooking. Here are some of the most popular uses:
- Fried Green Tomatoes: A Southern classic, this dish capitalizes on the tomato's firm texture. Sliced and coated in a mix of cornmeal and flour, then pan-fried, they become crispy on the outside and tender on the inside. They are delicious served with a spicy remoulade or a simple ranch dressing.
- Green Tomato Chutney: The natural tartness of unripe tomatoes makes them an excellent base for a sweet and tangy chutney. Cook chopped green tomatoes with apples, onions, vinegar, and a blend of spices like ginger, mustard seed, and turmeric. This preserves your harvest and creates a condiment perfect for cheese boards or curries.
- Green Tomato Salsa Verde: Substitute green tomatoes for tomatillos to make a zesty, fresh salsa. Roast them with garlic, onions, and jalapeños, then blend with cilantro and lime juice for a versatile salsa that pairs well with tacos or grilled meats.
- Pickled Green Tomatoes: For a long-lasting and flavorful treat, pickle sliced or whole green tomatoes. The process is similar to pickling cucumbers, using a brine of vinegar, water, and spices like dill and mustard seed. This is a fantastic way to enjoy your harvest throughout the winter.
Comparison Table: Ripening vs. Cooking
| Feature | Indoor Ripening | Culinary Use (Cooking) |
|---|---|---|
| Tomato Condition | Slightly blushed or fully green, but with some size. | Firm, hard, and unripe. |
| Flavor Profile | Develops into a sweeter, classic red tomato taste. | Retains a tart, acidic, and tangy flavor. |
| Best For | Eating fresh in salads, sandwiches, or sauces. | Frying, pickling, making chutney, or salsa. |
| Timeframe | Takes days to several weeks, depending on the method. | Can be done immediately after harvesting. |
| Yield | Fewer tomatoes may ripen successfully. | All unripe tomatoes can be utilized. |
| Storage Method | Stored in paper bags or boxes in a cool, dark place. | Can be canned, frozen (as puree), or refrigerated. |
Considerations for Preserving Your Harvest
If you're dealing with a large volume of unripe tomatoes, preserving them is a great option. Canning green tomato chutney or pickling slices can extend the life of your harvest for months or even years. Freezing is another simple method. Wash, chop, and blanch the green tomatoes before pureeing and freezing them in airtight containers for use in sauces later.
Conclusion
Unripe tomatoes are far from a lost cause. Whether you choose to ripen them naturally indoors with the help of a paper bag and a banana, or embrace their unique tartness in a new recipe, your end-of-season bounty offers a delicious opportunity. From a classic southern fried delicacy to a tangy, flavorful chutney, the options are plentiful. By sorting your tomatoes and using the right technique, you can save your harvest and enjoy its flavors well into the cooler months.

Frequently Asked Questions
What do unripe tomatoes taste like?
Unripe green tomatoes have a very different flavor profile than their ripe red counterparts. They are firm, tart, and acidic, which is why they are often used in cooked dishes that balance these flavors.
Are all green tomatoes the same?
No. Some tomato varieties are bred to remain green even when ripe, such as 'Green Zebra' or 'German Green'. These are not what's discussed here; this guide refers to standard red tomato varieties picked before they have fully ripened. The key difference is ripeness, not variety.
How can I make green tomatoes ripen faster?
Placing green tomatoes in a paper bag or a closed container with a ripe banana or apple will speed up the ripening process. The ethylene gas released by the ripe fruit triggers ripening in the tomatoes.
Can you eat green tomatoes raw?
It is not recommended to eat unripe green tomatoes raw due to their tartness and texture. Cooking them, however, breaks down their firmness and makes them delicious in various recipes.
What temperature is best for ripening tomatoes indoors?
Tomatoes ripen best indoors at temperatures between 60°F and 65°F. Keeping them in a cool, dry place out of direct sunlight, such as a pantry or basement, is ideal for a slow, even ripening process.
Can I freeze green tomatoes?
Yes, you can freeze green tomatoes. For best results, wash and chop the tomatoes, then puree them before freezing in airtight containers. This can be used later for sauces or stews.
Why are my tomatoes not ripening on the vine?
Several factors can cause tomatoes not to ripen on the vine, including extreme temperatures (too hot or too cold), excessive nitrogen in the soil, or simply an overabundance of fruit on one plant. Moving them indoors can often solve this problem.
