📝 Editor's Notes

The "Tomato Onion All-Purpose Sauce: Making Everyday Meals Easier" is a homemade sauce that's easy and healthy to prepare at home, using fresh tomatoes and onions as its main ingredients.

It's characterized by its sweet and sour profile with a deep umami flavor, making it a highly versatile sauce that pairs well with any dish.

This is an 'easy' level recipe that anyone can make without special skills.

If you make a generous batch when tomatoes are in season, from summer to fall, it will be a reliable base for your meals throughout the year.

It will be incredibly useful for those busy days when you still want to ensure a healthy meal.

🛒 Ingredient Tips

The key to this sauce lies in the freshness of the tomatoes and onions.

Choose tomatoes that have smooth, firm skin and feel heavy.

The stem area should be fresh and green.

Avoid any that are too soft or bruised.

For onions, select those with shiny, firm skins and no mold at the root end.

While 3 large onions are suitable, if using small onions, use 4 to fully bring out their sweet flavor, which will deepen the sauce's aroma even further.

Using seasonal tomatoes and onions allows you to maximize the natural flavors of the ingredients without needing artificial sweetness.

🔄 Substitution Guide

If you have a tomato allergy or fresh tomatoes are hard to find, you can use canned tomatoes.

Use 2-3 cans of whole peeled tomatoes (about 400g each).

In this case, the acidity of the tomatoes might be stronger, so increase the amount of sugar slightly or add a tablespoon of honey to balance the flavor.

If bay leaves are unavailable, you can omit them.

However, if you wish to add a herbal aroma, you can add about 0.5 tsp of dried herbs like oregano or basil for an exotic touch.

If using garlic powder instead of fresh garlic, use only about 1/2 tsp.

Remember, however, that using fresh ingredients will yield the deepest and richest flavor.

👨‍🍳 Cooking Points

There are two key cooking points for this recipe.

First, it's crucial to sauté the onions sufficiently to bring out their sweetness.

Sauté them over medium heat for 5-7 minutes until they become translucent and a sweet aroma develops.

Be careful not to sauté over too high heat, as this can burn the onions and result in a bitter taste.

Second, it's important to reduce the sauce sufficiently to achieve the right consistency.

After adding and simmering the tomatoes, season with salt, then reduce the heat to low and continue to simmer for 25-30 minutes with the lid slightly ajar.

Stirring occasionally to prevent sticking to the bottom is essential.

The ideal consistency is when you can push the sauce aside with a spatula and the bottom of the pot is visible for a moment; be careful not to over-reduce it.

👨‍🍳 Directions

1

Wash tomatoes thoroughly under running water, then remove the stems and any bruised or soft spots. If you prefer to remove the skin, blanch them in boiling water for about 30 seconds, then transfer to cold water and peel. Cut the tomatoes into large chunks.

2

Peel the onions, halve them, and then roughly slice them. Mince or slice the garlic.

3

Heat 2-3 tbsp of olive oil in a thick-bottomed pot over medium heat. Sauté the onions for 5-7 minutes until they become translucent and a sweet aroma develops. (Be careful not to sauté over too high heat.)

4

Once the onions are translucent, add the garlic and sauté briefly until fragrant. (Do not sauté for too long to prevent a bitter taste.)

5

Add all the chopped tomatoes, cover the pot, and simmer over medium heat for about 10 minutes. (Do not add water; the tomatoes will release their own moisture.)

6

After 10 minutes, when the tomatoes have softened and liquid has formed, mash the tomatoes with a spatula. (For a smoother sauce, blend briefly with an immersion blender.)

7

Add 1 tsp of salt, reduce heat to low, and simmer for another 25-30 minutes with the lid slightly ajar. (Be sure to stir occasionally to prevent sticking to the bottom.)

8

The sauce is done when the color deepens and it thickens. (When you push the sauce aside with a spatula and the bottom of the pot is visible for a moment, it's the right consistency. Be careful not to reduce it too much.)

9

Taste and adjust seasoning as desired by adding more salt, 0.5 tsp of sugar, black pepper, or 1 bay leaf.

10

Do not cover the finished sauce while hot. Let it cool completely before transferring to a clean container for storage.

💡 Tips

Sautéing the onions sufficiently first to bring out their sweetness helps to mellow the acidity of the tomatoes, allowing you to make a delicious sauce with less sugar.

This sauce can be used in a variety of dishes such as rice, egg dishes (fried eggs, scrambled eggs), meat dishes (pork, chicken), fish dishes (mackerel, Spanish mackerel), noodle dishes (noodles, pasta, ramen), and bread dishes (toast). Adding the sauce to each dish will enhance its taste and flavor.

Since this is a base sauce, it's best not to make it too salty from the start, which allows for greater versatility in various dishes. It's recommended to adjust the seasoning to your liking when serving with a meal.

Tomatoes are acidic, so those with sensitive stomachs or acid reflux should be cautious about consuming large amounts on an empty stomach. Onions can also cause bloating in some people, so try a small amount first.

Sauces stored in the refrigerator should be consumed within 3-5 days. For longer storage, portion the sauce into single servings, spread thinly in zip-top bags, and freeze. This makes it easy to cut off what you need and thaws quickly. (Room temperature storage without professional sterilization is risky.)

📦 Storage & Reuse

The finished sauce must be completely cooled before being stored in a clean, airtight container.

When refrigerated, it can be enjoyed fresh for about 5-7 days.

If you wish to store it longer, it's recommended to divide it into single-serving portions and freeze it.

Frozen, it can be stored for about 1-2 months.

To thaw, simply move it to the refrigerator for natural thawing or gently warm it in the microwave.

Leftover sauce can be mixed with rice, topped on fried eggs for a simple meal, or used as a sauce for chicken or pork dishes, ensuring no waste and delicious enjoyment.

🥢 Who This Is For

This all-purpose sauce is especially recommended for busy working mothers and those who often eat alone.

Preparing it in advance allows for easy use in a variety of dishes, from breakfast to dinner, enhancing your quality of life.

For family meals, it can complete a wonderful dish alongside pork steak or grilled chicken breast.

For children's snacks, serving it on toast or scrambled eggs makes for a highly nutritious option.

It's also a delightful treat when mixed with rice or used as a pasta sauce.
