Om morgenen koger jeg to æg, hvis jeg vil have en stor morgenmad.

Because Danish often puts a time expression first when it wants to set the scene: in the morning.

So:

• Om morgenen koger jeg to æg ... = emphasis on when
• Jeg koger to æg om morgenen ... = same basic meaning, but less fronted emphasis

Both are natural. Starting with Om morgenen is very common.

In this kind of time expression, Danish usually uses the definite form for parts of the day:

• om morgenen = in the morning
• om aftenen = in the evening
• om natten = at night

So this is a normal fixed pattern. It does not mean the morning in a very literal English sense; it is just how Danish commonly expresses this idea.

This is because Danish follows the V2 rule in main clauses: the finite verb normally comes in the second position.

In this sentence, Om morgenen takes the first position, so the verb koger must come next:

• Om morgenen | koger | jeg | to æg ...

If the subject comes first, then the order is:

• Jeg koger to æg om morgenen ...

So both are correct, but the word order changes depending on what comes first.

Koger is the present tense of at koge.

• at koge = to boil
• jeg koger = I boil / I am boiling

For many Danish verbs, the present tense is formed by adding -r:

• at have → har
• at ville → vil
• at koge → koger

Here, koger means boil or cook by boiling.

Because æg is one of those Danish nouns whose singular and plural indefinite forms are the same.

• et æg = an egg
• to æg = two eggs

So the number word to tells you it is plural.

The definite plural is different:

• æggene = the eggs

Because hvis introduces a subordinate clause, and subordinate clauses usually have a different word order from main clauses.

In a main clause, Danish follows the V2 rule:

• Jeg vil have en stor morgenmad

But after hvis, the subject normally comes before the finite verb:

• hvis jeg vil have en stor morgenmad

So:

• main clause: verb in second position
• subordinate clause: subject + verb is normal

Here vil have means something like want or want to have.

So jeg vil have en stor morgenmad means:

• I want a big breakfast
• or more literally, I want to have a big breakfast

In everyday Danish, ville have is a very common way to express wanting something. It does not sound strange or overly literal.

Because morgenmad is a common-gender noun, so it takes:

• en in the singular indefinite
• the adjective form stor

So:

• en stor morgenmad

Compare with a neuter noun, where you would get et stort ...

Also, stor morgenmad usually means a substantial or hearty breakfast, not just a physically large one.

Usually it suggests a general or habitual time, something like:

• in the morning
• in the mornings

Because the sentence is in the present tense and describes a repeated kind of situation, it sounds like a habit or usual pattern.

If you wanted to say this morning, Danish would usually use a different expression, such as i morges.

Because hvis jeg vil have en stor morgenmad is a subordinate clause.

In many Danish texts, a comma is placed before subordinate clauses like this. However, Danish also has a comma system where this start comma can be omitted, so you may sometimes see:

• Om morgenen koger jeg to æg hvis jeg vil have en stor morgenmad.

and sometimes:

• Om morgenen koger jeg to æg, hvis jeg vil have en stor morgenmad.

So the comma is normal, but you may encounter both styles.
