Bu ekmek çok gevrek, bu yüzden çorbanın yanında güzel gidiyor.

The two bu words do different jobs:

• Bu ekmek = this bread
• bu yüzden = for this reason / therefore / so

So the first bu is a demonstrative adjective pointing to the bread, while the second is part of the fixed expression bu yüzden, which connects the two clauses.

Gevrek means crispy, crunchy, or crisp.

For bread, it usually suggests that the outside has a nice crunchy texture. It is a very natural word for foods like bread, pastry, or simit.

In Turkish, çok is the normal word used to mean very before adjectives.

• çok gevrek = very crispy

So çok works like very here, not like many/much.

Bu yüzden means because of this, for this reason, or more naturally in English, so or therefore.

It connects the first idea to the result:

• Bu ekmek çok gevrek = This bread is very crispy.
• bu yüzden... = so / therefore...

It is a common linking expression in Turkish.

This is because yanında means beside it / next to it / with it, and it usually follows a noun in the genitive form.

So:

• çorba = soup
• çorbanın = of the soup
• yanında = at its side / alongside it

Together:

• çorbanın yanında = with the soup / alongside the soup

This is a very common Turkish structure:

• evin yanında = next to the house
• masanın üstünde = on the table
• okulun önünde = in front of the school

Yanında comes from:

• yan = side
• -ı = possessive ending (its side)
• -nda = locative ending (in/on/at)

So literally, çorbanın yanında is something like at the soup’s side.

But in natural English, it usually means:

• with the soup
• alongside the soup
• next to the soup

Yes, literally gidiyor means is going, but in Turkish iyi/gitmek or güzel gitmek can be used idiomatically for food, drink, clothes, colors, and combinations.

Here güzel gidiyor means something like:

• goes well
• pairs well
• works well

So:

• çorbanın yanında güzel gidiyor = it goes well with soup

This is a very natural Turkish expression.

Both can work, but they feel slightly different.

• gider = aorist/simple present; often used for general truths or habitual statements
• gidiyor = present continuous; often used in modern Turkish for a current situation or a more immediate judgment

In everyday speech, Turkish often uses -iyor forms where English might use a simple present.

So güzel gidiyor here can sound like:

• it goes well
• it’s going well
• it works nicely

If you said güzel gider, it would also be understandable and natural, with a slightly more general feel.

Turkish often leaves out the subject when it is understood from context.

Here the subject is clearly bu ekmek from the first clause, so Turkish does not need a separate word for it.

So the second part is understood as:

• (Bu ekmek) çorbanın yanında güzel gidiyor.
• (This bread) goes well with soup.

This kind of subject-dropping is extremely common in Turkish.

Turkish word order is flexible, but it often puts important descriptive phrases before the verb.

Here:

• Bu ekmek = subject
• çok gevrek = description
• bu yüzden = connector
• çorbanın yanında = with the soup
• güzel gidiyor = goes well

The verb usually comes near the end in Turkish, which is one of the biggest differences from English.

Yes. Yanında can mean both:

• next to / beside
• with / alongside

Examples:

• Okulun yanında bir park var. = There is a park next to the school.
• Balığın yanında salata güzel gider. = Salad goes well with fish.

In your sentence, it is not really about physical location. It means as something served with soup.

It depends on context.

• Bu ekmek can mean this bread in a general sense
• It can also refer to a specific loaf, roll, or bread being served

Turkish does not force the same kind of distinction English sometimes does. The context tells you whether it means bread in general or a particular bread item.

Yes, çorbayla güzel gidiyor is also possible.

• çorbayla = with soup
• çorbanın yanında = alongside the soup / with the soup

The difference is small:

• çorbayla focuses more directly on the pairing
• çorbanın yanında suggests being served next to or together with the soup

Both are natural, but çorbanın yanında sounds especially good for food served as a side.

Yes, it is natural and idiomatic.

Especially natural parts are:

• çok gevrek
• bu yüzden
• çorbanın yanında
• güzel gidiyor

A native speaker might also say:

• Bu ekmek çok gevrek, o yüzden çorbanın yanında güzel gidiyor.
• Bu ekmek çok gevrek; çorbayla çok iyi gidiyor.

But your original sentence sounds perfectly normal.
