는 is the topic marker. In 소고기는, the speaker is setting beef up as the topic and saying something about it.

So the sentence has the feel of:

• As for beef, it’s a little expensive, but...
• Beef is a little expensive, but...

Using 는 can also give a slight contrastive feeling, especially because the sentence compares two ideas:

• it is expensive
• but it makes the soup richer

So 소고기는 sounds natural here because the speaker is discussing beef as a category and then giving a balanced opinion about it.

Both mean beef.

• 소고기 is the more common everyday form in modern Korean.
• 쇠고기 is also correct, but it can sound a bit more traditional or dictionary-like to some learners.

In normal conversation, you will hear 소고기 very often.

Here 조금 means a little or somewhat, so 조금 비싸지만 means it’s a little expensive, but...

It often softens the statement. Instead of saying beef is plainly expensive, the speaker says it is a bit expensive.

Common uses of 조금:

• 조금 비싸요 = It’s a little expensive.
• 조금만 기다리세요 = Please wait a moment / wait a little.
• 물을 조금 마셨어요 = I drank a little water.

So yes, it often means a little, but the exact nuance depends on context.

비싸지만 comes from:

• 비싸다 = to be expensive
• -지만 = but / although

So:

• 비싸다 → stem 비싸-
• 비싸지만 = it is expensive, but...

The ending -지만 connects two clauses that contrast with each other.

Examples:

• 비싸지만 좋아요 = It’s expensive, but it’s good.
• 어렵지만 재미있어요 = It’s difficult, but it’s interesting.

In your sentence, 비싸지만 sets up the contrast:

• beef is a little expensive
• but when you put it in soup, the flavor becomes richer

Because 국 is the place/container that something is put into, not the thing being put.

• 에 marks the location or destination: into the soup
• 넣다 means to put in

So:

• 국에 넣으면 = if/when you put it in soup

If you said 국을 넣으면, that would mean if/when you put in the soup, making soup the object being inserted somewhere else. That is not the intended meaning here.

You can think of it like this:

• 무엇을 넣어요? = What do you put in? → the object would be beef
• 어디에 넣어요? = Where do you put it? → 국에

The beef is understood from context, so only 국에 is explicitly stated.

It certainly can be repeated, and 소고기를 국에 넣으면 is grammatically correct.

But Korean often omits words that are clear from context. Since the sentence already started with 소고기는, listeners naturally understand that the thing being put into the soup is beef.

So:

• 소고기는 조금 비싸지만 국에 넣으면 맛이 진해져요.
• 소고기는 조금 비싸지만 소고기를 국에 넣으면 맛이 진해져요.

Both are understandable, but the first sounds more natural because Korean often avoids repeating obvious information.

-으면 / -면 is a conditional ending meaning if or when.

• 넣다 = to put in
• 넣으면 = if you put it in / when you put it in

In this sentence, it has a general truth kind of meaning:

• If you put beef in soup, the flavor gets richer

It is not only about one single occasion. It sounds like a general cooking fact or recommendation.

Formation:

• consonant-ending stem + -으면
• vowel-ending stem + -면

Examples:

• 먹으면 = if/when you eat
• 가면 = if/when you go
• 읽으면 = if/when you read

Because 맛 is the thing that is becoming rich/thick/strong in flavor, so it functions as the subject of 진해져요.

• 맛이 진해져요 = the flavor becomes richer/deeper

With verbs like 되다, 변하다, 커지다, 작아지다, 진해지다, the thing undergoing the change is usually marked with 이/가.

Compare:

• 맛이 좋아요 = The taste is good.
• 맛이 진해져요 = The flavor becomes stronger/richer.

If you used 맛을, it would suggest that 맛 is the direct object of another action, which is not what is happening here.

진해져요 comes from 진하다, which means to be thick, deep, strong, rich depending on context.

For flavor, 진하다 often means:

• rich
• deep
• strong
• full-bodied

The form 진해지다 means to become rich/deep/strong.

Formation:

• 진하다 → 진해지다 = to become richer/deeper
• 진해져요 is the polite present form of 진해지다

So:

• 맛이 진해져요 = the flavor becomes richer/deeper

This -아/어지다 pattern is very useful:

• 커지다 = to become big
• 작아지다 = to become small
• 약해지다 = to become weak
• 진해지다 = to become rich/strong/deep

Not exactly. They are related, but not identical.

• 국: soup, usually lighter
• 탕: soup as well, often heartier or used in dish names
• 찌개: stew, usually thicker and stronger

So in this sentence, 국 suggests soup, and the idea is that adding beef makes the soup’s flavor richer.

You do not need to memorize a perfect English equivalent for every case, because these categories do not match English exactly. But for learners:

• 국 = soup
• 찌개 = stew

is a good starting point.

진해져요 is in the polite informal style, which is one of the most common spoken styles in Korean.

It is polite enough for everyday conversation and very common in explanations, comments, and recommendations.

Compare:

• 진해져요 = polite
• 진해져 = casual/intimate
• 진해집니다 = more formal

So the whole sentence sounds like a natural, polite statement someone might say in conversation, such as when talking about cooking.

It can be understood as either if or when, depending on how naturally you would say it in English.

Korean -으면/-면 often covers both:

• if
• when

In this sentence, the meaning is closer to a general fact:

• When you put beef in soup, the flavor gets richer
• If you put beef in soup, the flavor gets richer

Both are fine in English. The Korean is not emphasizing uncertainty; it is stating a general result.

A helpful breakdown is:

• 소고기는 = as for beef
• 조금 비싸지만 = it is a little expensive, but
• 국에 넣으면 = if/when you put it in soup
• 맛이 진해져요 = the flavor becomes richer

So the logic is:

As for beef, it’s a little expensive, but if you put it in soup, the flavor becomes richer.

This is very normal Korean sentence structure:

1. topic
2. description
3. condition or background
4. main result

Korean often saves the main point for the end, so learners should get used to waiting for the final verb.
